Myesha has a bag that contains orange chews, lemon chews, and lime chews. She performs an experiment. Myesha randomly removes a chew from the bag, records the result, and returns the chew to the bag. Myesha performs the experiment 17 times. The results are shown below:
A orange chew was selected 12 times.
A lemon chew was selected 2 times.
A lime chew was selected 3 times.

Based on these results, express the probability that the next chew Myesha removes from the bag will be a flavor other than lime as a percent to the nearest whole number.

Answers

The probability that the next chew Myesha removes from the bag will be a flavor other than lime is 82%.

What is probability?

Probability is the measure of the likelihood or chance of an event occurring. It is a numerical value between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain to occur. Probabilities between 0 and 1 represent the degree of uncertainty about whether the event will occur or not.

Out of the 17 times Myesha performed the experiment, a lime chew was selected 3 times. Therefore, the probability that the next chew Myesha removes from the bag will be a lime chew is 3/17.

To find the probability that the next chew Myesha removes from the bag will be a flavor other than lime, we need to subtract the probability of getting a lime chew from 1.

P(flavor other than lime) = 1 - P(lime)

P(flavor other than lime) = 1 - 3/17

P(flavor other than lime) = 14/17

To express this probability as a percent to the nearest whole number, we multiply by 100 and round to the nearest integer:

P(flavor other than lime) = 14/17 x 100

P(flavor other than lime) = 82.35

P(flavor other than lime) ≈ 82%

Therefore, the probability that the next chew Myesha removes from the bag will be a flavor other than lime is approximately 82%.

To determine whether it is valid to claim that the amount of is lower, we need to compare this probability to our chosen cut-off for unusual events, which is 5%.

What is the probability of randomly selecting?

To find the probability of randomly selecting 37 with a mean of   [tex]0.897 g[/tex]  or less, we need to calculate the z-score and look up the corresponding probability in the standard normal distribution table.

Where X is the sample mean   [tex](0.897 g),[/tex] μ is the population mean (0.951 g), σ is the population standard deviation [tex](0.299 g)[/tex]  , and n is the sample size (37).

Drag the number cards so that the values of x are as small as possible

Answers

By dragging the number cards to form the lowest sum possible and substituting that sum into the formula for x, we can make the value of x as small as possible.

The formula for x is x = (a + b + c + d)/4. In order to minimize the value of x, we should aim to make the sum of a, b, c, and d as small as possible. To do this, we can drag the number cards to form the lowest sum possible. For example, if the number cards are 5, 6, 7, and 8, we can drag them to form the sum of 26 (5 + 6 + 7 + 8 = 26). To calculate the value of x, we can substitute the sum of the numbers in the formula and divide it by 4. In this example, x = (26/4) = 6.5. By using this strategy, we can minimize the value of x and make it as small as possible.

is the sample standard deviation of Ervin's

scores?

Answers

The sample standard deviation of Ervin's scores is 41.81.

In this problem, we are given the scores of 7 games bowled by Ervin, and we are asked to calculate the sample standard deviation of these scores. To calculate the sample standard deviation, we first need to calculate the sample mean, which is the sum of the scores divided by the number of games:

mean = (155 + 165 + 138 + 172 + 127 + 193 + 142) / 7 = 138.57

Next, we need to calculate the variance, which is the sum of the squared differences from the mean, divided by the number of games minus one:

variance = [(155-138.57)² + (165-138.57)² + (138-138.57)² + (172-138.57)² + (127-138.57)² + (193-138.57)² + (142-138.57)²] / (7-1) = 1749.62

Finally, we can calculate the sample standard deviation by taking the square root of the variance:

standard deviation = √(variance) = √(1749.62) = 41.81

Mail surveys have the concern of _____ but have the advantage of _____. Group of answer choices low return rate; eliminating interviewer bias interviewer bias; high return rate sampling bias; interviewer bias increasing socially desirable responses; high return rate

Answers

The correct option is a low return rate; eliminating interviewer bias. Mail surveys have the concern of low return rate but have the advantage of eliminating interviewer bias.

A mail survey is a form of a self-administered survey in which the questionnaire is sent to the respondent through the post. Mail surveys are convenient because they allow participants to respond on their schedule and in the privacy of their own homes.

Mail surveys have the concern of a low return rate but have the advantage of eliminating interviewer bias. The concern of mail surveys is a low return rate. One of the greatest advantages of mail surveys is that they do not require any interaction between the researcher and the respondent. Mail surveys' response rate is typically lower than phone or face-to-face surveys. However, it eliminates interviewer bias.

Interviewer bias occurs when the interviewer's characteristics or behavior have an impact on the participant's responses. Interviewer bias can occur in face-to-face interviews or phone surveys. Respondents may attempt to please the interviewer or present themselves in a more favorable light than they otherwise would in order to avoid social disapproval.

What is the answer?

Answers

The area of composite figure composed of a sector and triangle is 95.52 cm²

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables. Equations can either be linear, quadratic, cubic and so on depending on the degree.

To get the area of the composite figure, we add the area of the sector to the area of the triangle.

Area of circle sector = (Ф / 360) * π * radius²

but Ф = 82°, radius = 10 cm, π = 3.14, hence:

Area of circle sector = (82 / 360) * 3.14 * 10² = 71.52 cm²

Area of triangle = (1/2) * base * height

but base = 6 cm, height = 8 cm, therefore:

Area of triangle = (1/2) * 6 * 8 = 24 cm²

Area of composite figure = 24 cm² + 71.52 cm² = 95.52 cm²

The two numbers are x = 3 and y = 8.

Let x and y represent two numbers.

x + y = 16

xy = 24

To solve for the values of x and y, we can use the two equations given. We can first solve for x by dividing both sides of the second equation by y:

xy/y = 24/y

x = 24/y

We can substitute this value for x in the first equation and solve for y:

x + y = 16

(24/y) + y = 16

24 + y^2 = 16y

y^2 - 16y + 24 = 0

(y - 8)(y - 3) = 0

y = 8 or y = 3

Now that we have values for y, we can substitute them into the second equation and solve for x:

xy = 24

x = 3

Answers

The standard deviation of the costs is 37 Dhs

The given mean is 173 and 3% of costs exceed 243. We have to calculate the standard deviation of the cost. Therefore, let's first start by calculating the z-score as follows;z-score formula = `(x - μ) / σ`z-score = `243 - 173 / σ`z-score = `70 / σ`We need to find the standard deviation of the costs. Since the z-score formula includes standard deviation, we can first calculate the z-score and then use it to calculate the standard deviation.Using the z-table, we can find the z-score for 3% = -1.88-1.88 = (243 - 173) / σσ = (243 - 173) / -1.88σ = -70 / -1.88σ = 37.23≈ 37The standard deviation of the costs is 37 Dhs.

What is angle?  

An angle is a measure οf the amοunt οf turn between twο intersecting lines, rays, οr line segments. It is typically measured in degrees οr radians. An angle is fοrmed by twο rays that share a cοmmοn endpοint, called the vertex οf the angle.

In a cοnvex pοlygοn, the sum οf the exteriοr angles is always 360 degrees. This is knοwn as the Exteriοr Angle Sum Theοrem.

Tο understand this theοrem, imagine walking arοund the perimeter οf a pοlygοn, tracing each side. At each vertex, yοu turn an angle tο cοntinue alοng the next side. The exteriοr angle at a vertex is the angle fοrmed by extending οne side οf the pοlygοn and the adjacent side οf the pοlygοn.

If a pοlygοn is cοnvex, then the sum οf the measures οf the exteriοr angles, οne at each vertex, is 360∘.

Tο find the measure οf each exteriοr angle οf a regular pοlygοn, yοu just divide:

would have a cat and dog?

Answers

7 out of the 30 individuals—or 25%—would be predicted to own both a dog and a cat for two events based on laws of probability multiplication.

The probability multiplication method can be used to determine the number of persons who own both a dog and a cat if we assume that owning either one is an independent occurrence.

We are aware that 15 out of the 30 people—or 50%—have cats. Also, 12 out of the 30 people, or 40%, are dog owners. The likelihood of owning both a cat and a dog is just the sum of the probabilities of owning both a cat and a dog if we believe that these events are unrelated:

P(having a dog and a cat) = P(having a cat) * (owning a dog)

P (having a dog and a cat) equals (15/30) * (12/30).

P(having a dog and a cat) = 0.25

7.5 out of the 30 individuals—or 25%—would be predicted to own both a dog and a cat. We cannot allow a fraction of a person to possess both a cat and a dog though, as we are dealing with a discrete number of people. As a result, we can round to the next whole number or down. As there cannot be a half of a person in this situation, we would round down to 7 people having both a dog and a cat.

How to find if there will be enough room for mike

The diagonal of a cuboid is a line segment that connects two opposite corners of the cuboid. It passes through the center of the cuboid and represents the longest distance between any two points in the cuboid.

If the diagonal is less than 13 inch then there will not be enough room if otherwise then there will be enough room

To find the diagonal of a cuboid, you can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

In a cuboid, if we label the length, width, and height

diagonal = √(length^2 + width^2 + height^2)

diagonal = √(10^2 + 8^2 + 12^2)

diagonal = √308

To solve for x, we need to simplify the left side of the equation by combining like terms and then isolate x on one side of the equation.

First, let's combine the like terms:

5x + 3x = 8x

-7 + 27 = 20

So the equation simplifies to:

8x + 20 = 180

Next, let's isolate x by subtracting 20 from both sides:

8x + 20 - 20 = 180 - 20

8x = 160

Finally, we can solve for x by dividing both sides by 8:

8x/8 = 160/8

x = 20

70% of the time, it takes more than 6.04 minutes to find a parking space. Rounded to two decimal places, the answer is 6.04 minutes.

The length of time it takes to find a parking space at 9 a.m. follows a normal distribution with a mean of 5 minutes and a standard deviation of 2 minutes. To find the time it takes to find a parking space 70% of the time, we need to find the z-score that corresponds to the 70th percentile.

Using a z-table, we find that the z-score corresponding to the 70th percentile is 0.52. Using the formula z = (x - μ) / σ, where x is the value we are trying to find, μ is the mean, and σ is the standard deviation, we can plug in the values and solve for x:

0.52 = (x - 5) / 2

x - 5 = 0.52 * 2

x - 5 = 1.04

x = 6.04

Therefore, 70% of the time, it takes more than 6.04 minutes to find a parking space. Rounded to two decimal places, the answer is 6.04 minutes.

Follow through this example before doing the problem.
Jake has enough in the budget to stock 12,000 trout and perch in the lake.
He wants to stock twice as many perch as trout. How many of each fish can
be used under these conditions?
Let t= number of trout
Let p= number of perch
t + p = 12,000
Since there are more perch (p) than trout (t), to set them equal to
each other, you would need to double the trout (t).
2t = p
Now solve for t and p using substitution. Since p = 2t, substitute
this equation (1)
t + p = 12000
t+ 2t = 12000
3t = 12000
12000-4000 = 8,000 perch
Now try this problem:
In this year's winter mammal census, the total number of wolves
and deer counted 495. Last year 7 times as many deer
and 9 times as many wolves were counted for a total of 3775 mammals.
How many of each type of mammal was
counted thi winter?
number of wolves =
number of deer=

Answers

The amounts of each type of animal are given as follows:

Wolves = 340.Deer = 155.

How to obtain the amounts?

The amounts are obtained solving a system of equations, for which the variables are given as follows:

Variable x: number of wolves.Variable y: number of deer.

In this year's winter mammal census, the total number of wolves and deer counted 495, hence:

x + y = 495.

x = 495 - y.

Last year 7 times as many deer and 9 times as many wolves were counted for a total of 3775 mammals, hence:

7x + 9y = 3775.

Replacing the first equation into the second, the value of y is given as follows:

7(495 - y) + 9y = 3775

2y = 310

y = 310/2

y = 155.

Then the value of x is given as follows:

x = 495 - 155

x = 340.

Un granjero tiene pienso para alimentar a sus 12 vacas durante 45 días, si compra 3 vacas más, ¿Cuánto le durará el pienso?

Answers

He can feed 15 cows till 36 days because earlier he feed 12 cows till 42 days. So we see we uses the concepts inversely proportional.

What is inversely proportional?

In this type of proportional is if their are two quantities then if first one is increase then automatically second one is decrease.

Suppose if a, b are two variables , and if they are indirectly proportional then we can write it as a ∝ 1/b , that means xy = k(where k is constant).

Let number of day be x days.

and, total number of cows = 12 + 3 (After he buy 3 more cow)

then, Number of cows and the number of days are inversely proportion.

So, we can write  [tex]\frac{12}{15} = \frac{x}{45}[/tex]

[tex]= x * 15 = 12 * 45[/tex]

[tex]\implies x = 36\ days[/tex]

So, He can feed 15 cows till 36 days.

point) Solve the equation 3x²+26x+48=0 byfactoring.the solution for x1and x2=with x1

Answers

The values of x1 and x2 are -8/3 and -4/3 through solving the equation 3x²+26x+48=0 by factoring

The equation mentioned in the question  is 3x² + 26x + 48 = 0. We need to solve this equation by factoring.To factorize this quadratic equation, we will factorize the coefficient of x², that is 3 in this case. The prime factors of 3 are 3 and 1. Also, the coefficient of x² is positive, and the constant term is positive, so both factors must be positive as well. Therefore, we write 3x² as (3x + p) (x + q), where p and q are two constants.

By multiplying these two factors, we get: 3x² + 3qx + px + pq = 3x² + (3q + p) x + pq .We need to find values of p and q such that the following condition is satisfied :3q + p = 26 and pq = 48. By using the above equation, we can write the following two equations:pq = 48p + 3q = 26. Now, we need to find the value of p and q by solving these equations. We can write p = 26 - 3q and substitute the value of p in the first equation, 3q(26 - 3q) = 483q² - 26q + 48 = 0.By solving this equation, we get the value of q, which is 2/3 or 8.

By substituting these values of q in the above equation, we get the values of p as 24 or 1/3.Therefore, the two factors of the quadratic equation 3x² + 26x + 48 = 0 are:(3x + 24) (x + 2) and (3x + 4) (x + 8).Solving the above two factors, we get x = - 8/3 and x = - 4/3.respectively.

X1=-8 AND X2=-1

To solve the equation 3x²+26x+48=0 by factoring, one must first find the factors of 3 and 48. Here is the solution:

Step-by-step solution:

Given: 3x²+26x+48=0

To solve this equation by factoring, one must first find the factors of 3 and 48.

Factors of 3 = 1, 3.

Factors of 48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48.

Now, to make the sum of the middle term 26x, we need to add 3x and 24x.

3x is a factor of 3x² and 24 is a factor of 48.

3x²+3x+24x+24 = 0

Dividing both sides by 3, we get:

x² + 9x + 8 = 0

Factoring the above quadratic equation, we get:

(x+8)(x+1) = 0

So, x+8=0 or x+1=0

Therefore, x=-8 or x=-1

The solution for x1 and x2 are x=-8 and x=-1 respectively.

Hence, the correct answer is "X1=-8 AND X2=-1".

A shop is having a sale. Each day, prices are reduced by 20% of the price on the
previous day.
Before the start of the sale, the price of a television is £450.
On the first day of the sale, the price is reduced by 20%.
(a) Work out the price of the television on
i) the first day of the sale
ii) the third day of the sale.

Answers

(a) i) The price of the television on the first day of the sale is £360

    ii) The price of the television on the third day of the sale is £288

(a)

i) On the first day of the sale, the price of the television is reduced by 20% of £450, which is:

20/100 × £450 = £90

So the price of the television on the first day of the sale is:

£450 - £90 = £360

ii) On the third day of the sale, the price of the television is reduced by 20% of the price on the second day of the sale. To find the price on the second day, we need to calculate the reduction on the first day and subtract it from the original price:

Reduction on first day = 20/100 × £450 = £90

Price on second day = £450 - £90 = £360

On the second day of the sale, the price of the television is reduced by 20% of £360, which is:

20/100 × £360 = £72

So the price of the television on the third day of the sale is:

£360 - £72 = £288
