Step-by-step explanation:

There are a total of 30 number between 1 and 30, so the total events is 30.
Now for the favorable events (A: even and multiple of 3) there's a total of 5 numbers (6,12,18,24,30)

Using classic probability law the probability is given by the favorable events between the total events

[tex]P(A)=\frac{6}{30}=\frac{1}{5}[/tex]

Accοrding tο the given infοrmatiοn, the prοbability οf generating a randοm number between 0.25 and 0.75 is 0.5 and the prοbability οf generating a number less than οr equal tο 1 is 1.

Prοbability is a measure οf the likelihοοd οr chance οf an event οccurring. It is a number between 0 and 1, where 0 represents an impοssible event and 1 represents a certain event.

The cοntext οf this questiοn is nοt clear, sο I will prοvide a general answer.

Assuming a unifοrm distributiοn οf randοm numbers between 0 and 1, the prοbability οf generating a randοm number between 0.25 and 0.75 is:

b. P(0.25 ≤ X ≤ 0.75) = 0.75 - 0.25 = 0.5

where X is the randοm variable representing the generated number.

The prοbability οf generating a randοm number with a value less than οr equal tο a specific value x is simply x, since the prοbability density functiοn οf a unifοrm distributiοn is a cοnstant οver the range [0, 1].

c. P(X ≤ x) = x fοr 0 ≤ x ≤ 1

Fοr example, the prοbability οf generating a number less than οr equal tο 0.3 is 0.3, and the prοbability οf generating a number less than οr equal tο 1 is 1.

the common ratio of the geometeric sequence -7, -42, -252 is 6.

A geometric sequence is a sequence of numbers where each term is obtained by multiplying the previous term by a fixed non-zero constant, called the common ratio. We can find the common ratio (r) of the sequence -7, -42, -252 by dividing any term by its previous term. For example:

-42 / (-7) = 6

-252 / (-42) = 6

Since the ratio is the same for both, we can conclude that the common ratio is 6. Therefore, each term is obtained by multiplying the previous term by 6.

To check, we can multiply any term by 6 to obtain the next term in the sequence. For example:

-7 * 6 = -42

-42 * 6 = -252

So, the common ratio of the sequence -7, -42, -252 is 6.

Simple interest is calculated as $3000 x 2.5% = $76. Compound interest is added to the principal to determine the balance for the next period.

Simple interest is a type of interest calculation that only takes into account the principal amount of a loan or investment. It does not include any additional payments (or compounding) of the interest. It is calculated by multiplying the principal amount by the interest rate and the number of periods for which the loan is taken out.

For Suzanne's investment, the annual interest rate is [tex]$2.5 %$[/tex], and the interest is simple. Therefore, the interest she earns each year is [tex]$$ I = P \times r = 3000 \times 0.025 = 75. $$[/tex]

Her balance at the end of each year is the sum of her initial deposit and the interest earned in that year. The completed table is:

After 50 seconds, the person has fallen approximately 2252.5 meters below the cliff.

Assuming no air resistance, we can use the formula for distance traveled by an object under constant acceleration:

d = v_i * t + (1/2) * a * t²

where d is the distance traveled, v_i is the initial velocity, t is the time, and a is the acceleration.

In this case, the initial velocity is -9.0 m/s (negative since it is downward), and the time is 50 seconds. The acceleration due to gravity is approximately -9.81 m/s².

Substituting the given values into the formula, we get:

d = -9.0 m/s * 50 s + (1/2) * (-9.81 m/s²) * (50 s)²

≈ -2252.5 m

Therefore, the person is approximately 2252.5 meters beneath the cliff after 50 seconds.

Using distance formula, the triangle ABC is a scalene triangle

To classify the triangle, we need to determine whether its sides are equal in length (in which case it's equilateral or isosceles), or whether they are all different lengths (in which case it's scalene). We can use the distance formula to calculate the length of each side of the triangle, as follows:

The distance formula gives us the distance between two points (x1, y1) and (x2, y2) in the coordinate plane:

d = √[(x2 - x1)^2 + (y2 - y1)^2]

Using this formula, we can find the length of each side of triangle ABC:

AB = √[(4-1)^2 + (4-0)^2] = √(9 + 16) = √25 = 5

BC = √[(6-4)^2 + (2-4)^2] = √(4 + 4) = 2√2

AC = √[(6-1)^2 + (2-0)^2] = √(25 + 4) = √29

We can see that AB = 5, BC = 2√2, and AC = √29. Since all three sides have different lengths, the triangle is scalene.

Note that the midpoints of the sides AB and BC are not relevant for determining the type of triangle. Also, it's not accurate to say that the midpoint of AB is (4/3, 2), as the coordinates of the midpoint are actually ((1+4)/2, (0+4)/2) = (2.5, 2), and similarly for the midpoint of BC.

To determine which size of shampoo is the better buy, we need to calculate the unit price, which is the price per ounce for each size.

For the regular size, the unit price is:

$8.00 / 20 oz = $0.40/oz

For the economy size, the unit price is:

$10.00 / 40 oz = $0.25/oz

Since the unit price for the economy size is lower than the unit price for the regular size, the economy size is the better buy.

Therefore, the economy size of shampoo is the better buy.

Step-by-step explanation:

25% can also be converted to 0.25

if you want to INCREASE it by 25%, you're adding 25% to your current 100% to get 125% of 80

125% is the same as 1.25, so you multiply 80 by 1.25

80 * 1.25 = 100

Answer:

100

Step-by-step explanation:

To increase 80 by 25%, you need to add 25% of 80 to 80.

First, we find what 25% of 80 is.

To find a percent of a number, multiply the percent by the number.

Change the percent to a decimal by dividing the percent by 100.

25% of 80 = 25% × 80 = 25/100 × 80 = 0.25 × 80 = 20

25% of 80 is 20.

Now we add 20 to 80.

80 + 20 = 100

If we are aware that Mustafa, Heloise, or Gia have penned more than [tex]22[/tex]pieces altogether. [tex]M > 8[/tex] This is the number of articles Mustafa might have written.

A numeric is a mathematical number which can be utilized to compute and describe a quantity. Numerical symbols, such as "3," are written to represent numbers. A counting system is a logical way of expressing numbers that uses digits or symbols to represent them.

The fact that we use a decimal (base 10) mathematical notation system for numbers gives the number 100 importance that it probably wouldn't otherwise have. It is a circular numeral with undertones of excellence.

[tex]M + H + A > 22[/tex]

We also know that:

[tex]H = 1/4M[/tex]

[tex]A = 3/2M[/tex]

We can substitute these expressions into the first equation:

[tex]M + 1/4M + 3/2M > 22[/tex]

Multiplying everything by the common denominator of 4:

[tex]4M + M + 6M > 88[/tex]

[tex]11M > 88[/tex]

[tex]M > 8[/tex]

So, Mufasa has written more than [tex]8[/tex] articles.

Using the equation [tex]H = 1/4M[/tex], we can find that Heloise has written:

[tex]H = 1/4(8) = 2[/tex]

Using the equation [tex]A = 3/2M[/tex], we can find that Angie has written:

[tex]A = 3/2(8) = 12[/tex]

Therefore, Mufasa has written more than [tex]8[/tex] articles, Heloise has written [tex]2[/tex]articles, and Angie has written [tex]12[/tex] articles.

To check if their combined total is more than [tex]22[/tex]:

[tex]M + H + A = 8 + 2 + 12 = 22[/tex]

Answer:

Step-by-step explanation:

To solve this problem, we need to find the number of cells in each colony after 1 minute (60 seconds) and compare them.

For the colony growing at 20°C, the expression for the number of cells is:

N(20°C) = t^2 - 7t - 7

Substituting t = 60 seconds:

N(20°C) = (60)^2 - 7(60) - 7 = 3533

Therefore, the number of cells in the colony growing at 20°C after 1 minute is 3533.

For the colony growing at 30°C, the expression for the number of cells is:

N(30°C) = t^2 - 6t - 7

Substituting t = 60 seconds:

N(30°C) = (60)^2 - 6(60) - 7 = 3563

Therefore, the number of cells in the colony growing at 30°C after 1 minute is 3563.

Comparing these results, we see that the colony growing at 30°C has a greater number of cells after 1 minute than the colony growing at 20°C. Therefore, the colony growing at 30°C will have a greater number of cells than the colony growing at 20°C after 1 minute.

In geometry, the perimeter of a circle or ellipse is its circumference. In other words, the circumference would equal the length of the arc if the circle were expanded up and straightened out to a line segment.

The term "perimeter" is most frequently used to describe the radius of any closed shape.

The circumference of a circle is the length around its periphery.

It is similar to the edges of other shapes, including squares.

It can be viewed as the line that defines the shape.

So, calculate the diameter using the Pythagorean theorem as follows:

h² = a² + b²

h² = 8² + 12²

h² = 64 + 144

h² = 208

h = √208

Through end behaviour of polynomials, we can see that the left end behaviour is approaching positive infinity and the right end behaviour is approaching negative infinity.

The nature of the value when the function argument gets closer to + infinity and - infinity is the end behaviour of a function.

The term with the highest degree determines how a polynomial function will behave in the end.

For example:

If f(x) = x³ + 2x² – 4x + 5 is given,

The end behaviour is determined by x³.

As a result, f(x) + as x + and f(x) - as x -

The term with the highest degree will be substantially larger than the other terms for large values of x, making the other terms essentially irrelevant.

The degree of the x³ coefficient is odd and it is positive.

Hence, the final behaviour is f(x) + as x + and f(x) - as x -.
