HELLP An Experiment Consists Of Rolling Two Fair Number Cubes. The Diagram Shows The Sample Space Of

Answers

Answer 1

The probability of rolling 1 and 2 is 1/36 of an experiment consists of rolling two fair number cubes.

Hence, the correct option is A

In the sample space diagram of rolling two number cubes, there are 36 equally likely outcomes since there are 6 possible outcomes for the first cube and 6 possible outcomes for the second cube. The outcome of rolling a 1 and 2 is shown in the sample space diagram and there is only one such outcome.

Therefore, the probability of rolling a 1 and 2 is

P(1 and 2) = (number of favorable outcomes) / (total number of outcomes) = 1/36

So the probability of rolling a 1 and 2 is 1/36.

Hence, the correct option is A

The double dot plot shows the values in two data sets.

Double dot plot shows the values of two data sets. It shows the number line ranges from 10 to 70 showing the following values that appear as dots above the line. For data set A. Two dots above 10. Three dots above 20. Four dots above 30. Two dots above 40. One dot above 50. For data set B. One dot above 30. Three dots above 40. Four dots above 50. Two dots above 60. Two dots above 70.

Compare the data sets using measures of center and variation.

Data set A Data set B
Median $=$
Median $=$
IQR $=$
IQR $=$

Answers

The    median for Data Set A is 30, and

median for Data Set B is 50.

The IQR for Data Set A is 20 (from 20 to 40), also   the IQR for Data Set B is also 20 (from 40   to 60).

What is  the explanation for the above  ?

To find the median we say   ......

For data set A, the median is:

The 6th value is the middle value, since there are 12 total values.

The 6th value =   30 on the number line,

since there are 2 dots above 10, 3 above 20, and 4 above 30.

Therefore, the median of data set A is 30.

For data set B, the median is:

The 7th and 8th values are the middle values, since there are 14 total values.

The 7th and 8th values =  50 on the number line,

since there are 4 dots above 50 and 2 dots above 60.

Hence, the median of data set B is 50.

To find the IQR, we need to find the range of the middle 50% of each data set.

For data set A, the IQR is:

The lower quartile is the 3rd value, which =  20 on the number line.

The upper quartile is the 9th value, = 40 on the number line.

The IQR is the difference between the upper and lower quartiles: 40 - 20 = 20.

For data set B, the IQR is:

The lower quartile is the 4th value, =  40 on the number line.

The upper quartile is the 11th value, = 70 on the number line.

Thus,

The IQR =  70 - 40 = 30.

Thus, data set B has a higher median than data set A,

And see that data set B has a larger IQR than data set A.

(4) Show that there is a nonabelian group of order 63. (Hint: Re- view the example of a group of order 21 from class and see if a you can modify that to find a nonabelian group of order 63 €

Answers

(1,0) has order 1 in C7 and order 1 in C3, and (0,1) has order 7 in C7 and order 1 in C3, we see that ((1,0),(0,1)) has order 7 in G and ((1,0),(1,0)) has order 3 in G. Similarly, ((1,1),(0,1)) has order 7 in G and ((1,1),(1,1)) has order 3 in G.

The group of order 21 is isomorphic to the cyclic group C7 x C3. We can use this group to construct a nonabelian group of order 63 as follows:

Consider the direct product of two groups of order 21: G = (C7 x C3) x (C7 x C3). Since the direct product of two abelian groups is also abelian, we know that G is not abelian if and only if it contains non-commuting elements.

Define two elements a = ((1,0),(0,1)) and b = ((1,1),(0,1)) in G. It can be shown that a and b have orders 3 and 7, respectively, and that they do not commute. Therefore, G is nonabelian.

To see why a and b have orders 3 and 7, respectively, note that the order of (g,h) in G is equal to the least common multiple of the orders of g and h in their respective groups. Since (1,0) has order 1 in C7 and order 1 in C3, and (0,1) has order 7 in C7 and order 1 in C3, we see that ((1,0),(0,1)) has order 7 in G and ((1,0),(1,0)) has order 3 in G. Similarly, ((1,1),(0,1)) has order 7 in G and ((1,1),(1,1)) has order 3 in G.

A bag contains seven red balls numbered 2, 4, 5, 6, 7, 8, 10 and three white balls numbered 1, 3, and 9. If a ball is drawn, what is the probability the ball is white or less than 3? Show all work.

Answers

The probability of drawing a ball that is white or less than 3 is 3/10 or 0.3.

We have,

There are 10 total balls in the bag.

The probability of drawing a white ball is 3/10 since there are three white balls out of ten total balls.

The probability of drawing a ball that is less than 3 is 1/10 since there is only one ball less than 3 (the white ball numbered 1) out of ten total balls.

To find the probability of drawing a ball that is white or less than 3, we need to add the probabilities of these two events occurring:

P(white or less than 3)

= P(white) + P(less than 3) - P(white and less than 3)

Since there is only one ball that satisfies both conditions (the white ball numbered 1), we can calculate P(white and less than 3) as 1/10.

P(white or less than 3) = 3/10 + 1/10 - 1/10

P(white or less than 3) = 3/10

Therefore,

The probability of drawing a ball that is white or less than 3 is 3/10 or 0.3.

- Mistakes made: The currency board system limited the government's ability to manage the money supply and respond to economic shocks. Also, the overvalued peso made Argentina's exports more expensive, which hurt the competitiveness of its industries.

- What happened as a result: Argentina faced a severe recession, high unemployment, and a massive public debt.

needed per person to live in Tyler, Texas?

PLS HELP
It’s just 7th grade math

Answers

To find the minimum monthly amount needed per person to live in Tyler, Texas, we need to add up the weekly expenses and multiply the result by the number of weeks in a month, which is 4.

So, the total weekly expenses are:

Housing $243
Utilities $97
Insurance $192
Transportation $194
Other $149
Taxes $124

Adding these up gives us:

$243 + $97 + $192 + $194 + $149 + $124 = $999

Now, we multiply this by 4 to get the minimum monthly amount needed per person:

$999 x 4 = $3,996

Therefore, the minimum monthly amount needed per person to live in Tyler, Texas is $3,996.

a closed cylindrical can has a fixed surface area s. find the ratio of its height to the diameter of its base that maximizes its volume.

Answers

The ratio of the height to the diameter that maximizes the volume of the cylindrical can is: 0.886 approximately.

Let the radius of the cylindrical can be denoted by r, and its height by h. The surface area of the can is given by:

S = 2π[tex]r^2[/tex]+ 2πrh

Simplifying this expression, we get:

h = (S - 2π[tex]r^2[/tex])/(2πr)

The volume of the cylindrical can is given by:

V = π[tex]r^2[/tex]h

Substituting the expression for h obtained earlier, we get:

V = π[tex]r^2[/tex](S - 2π[tex]r^2[/tex])/(2πr)

Simplifying this expression, we get:

V = (S/2π - [tex]r^2[/tex])πr

To maximize the volume of the cylindrical can, we need to find the value of r that maximizes the above expression. We can do this by differentiating the expression with respect to r, setting it equal to zero, and solving for r:

dV/dr = (S/2π - [tex]2r^2[/tex])π = 0

Solving for r, we get:

r = √(S/4π)

Substituting this value of r back into the expression for h, we get:

h = (S - 4π[tex]r^2[/tex])/(4πr) = (S - S/2)/(2√(S/4π)) = √(Sπ)/2

Therefore, the ratio of the height to the diameter that maximizes the volume of the cylindrical can is:

h/2r = (√(Sπ)/2)/(2√(S/4π)) = √(π/4) = 0.886 approximately.

The most appropriate statistical test to utilize in addressing the hypothesis that older students tend to make more complaints over minor details compared to their younger counterparts would be the chi-square test.

The chi-square test is used to analyze the categorical data and determine whether there is a significant association between two categorical variables. In this case, the two categorical variables would be the age group of the students (older vs. younger) and the frequency of complaints over minor details.

The researchers could collect data by randomly selecting a sample of older and younger students and recording the number of complaints made by each student over minor details. This data could then be organized into a contingency table with rows representing the age group of the students and columns representing the frequency of complaints.

Once the data is organized in this way, the chi-square test can be used to determine if there is a significant association between age group and frequency of complaints.

Approximately 25% of the tomatoes weigh less than which amount?

Answers

Approximately 25% of the tomatoes weigh less than 97.43 grams.

How to obtain probabilities using the normal distribution?

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution of the data-set, depending if the obtained z-score is positive(above the mean) or negative(below the mean).The z-score table is used to obtain the p-value of the z-score, and it represents the percentile of the measure X in the distribution.

The mean and the standard deviation for this problem are given as follows:

[tex]\mu = 95, \sigma = 3.6[/tex]

Approximately 25% of the tomatoes weigh less than the 25th percentile, which is X when Z = 0.675, hence:

0.675 = (X - 95)/3.6

Using this model, estimate the rate oI change of pressure with respect to time after 31 years. Round to the nearest hundredth ( 2 decimal places). ____ millimeters per year

Answers

Rounding to two decimal places, the rate of change of blood pressure with respect to time after 31 years is approximately 0.81 millimeters per year.

The mathematical model relating systolic blood pressure and age is given as P(x)=a+b*ln(x+1), we can differentiate it with respect to time (t) to find the rate of change of pressure with respect to time:

dP/dt = dP/dx * dx/dt

Here dx/dt is the rate of change of age with respect to time, which is simply 1 year per year or 1.

Taking the derivative of P(x) with respect to x, we get:

dP/dx = b/(x+1)

Substituting the given values for a and b, we have:

P(x) = 43 + 25ln(x+1)

dP/dx = 25/(x+1)

Therefore, the rate of change of pressure with respect to time after 31 years is:

6x - 9y = 18

Subtracting the second equation from the first, we get:

17y = 6

y = 6/17

Substituting y in the first equation, we get:

3x + 4(6/17) = 12

3x = 180/17 - 24/17

3x = 156/17

x = 52/17

Therefore, the solution of the given system is x = 52/17 and y = 6/17.

x + y = 3; x – y = 5

Adding the two equations, we get:

2x = 8

x = 4

Substituting x in the first equation, we get:

4 + y = 3

y = -1

Therefore, the solution of the given system is x = 4 and y = -1.

3x + 2y – z = 4; 2x – y + 3z = 4; x + y + 2z = 4

Adding the first and second equations, we get:

5x + y + 2z = 8

Subtracting the third equation from the above equation, we get:

4x + z = 4

Substituting z = 4 - 4x in the third equation, we get:

3x + 2y - (4 - 4x) = 4

7x + 2y = 8

Substituting y = (8 - 7x)/2 in the first equation, we get:

9x - z = 8

Substituting z = 4 - 4x, we get:

x = 4/5, y = 2/5, and z = 4/5

Therefore, the solution of the given system is x = 4/5, y = 2/5, and z = 4/5.

x – y + 5z = -4; 4x – 2y + 3z = 1; 3x – 2y + 6z = 6

Multiplying the first equation by -4 and adding it to the second equation, we get:

16x - 6z = 17

Multiplying the first equation by -3 and adding it to the third equation, we get:

9x + 4z = 18

Multiplying the second equation by 2 and subtracting it from the third equation, we get:

x + 6z = 8

Substituting z = (8 - x)/6 in the above equation, we get:

x = 10/3, y = 8/3, and z = 2/3

Therefore, the solution of the given system is x = 10/3, y = 8/3, and z = 2/3.

x2 + y2 = 13; 2x – 3y = -5

Squaring the second equation and simplifying, we get:

4x2 - 12xy + 9y2 = 25

Adding the above equation to the first equation, we get:

5x2 + 10y2 = 38

The area of a circle can be obtained from the use of formula πr^2

What is the circumference of the circle?

The circumference of a circle is the distance around the circle, which can be found using the formula; C = 2πr

where "C" is the circumference, "π" (pi) is a mathematical constant approximately equal to 3.14, and "r" is the radius of the circle.

Area of the circle = 3.14 * (3)^2 = 28.26 cm^2

C = 2 * 3.14 * 3 = 18.84

2) A = 3.14 * (17)^2 = 907.46

C = 2 * 3.14 * 17 = 106.76

3) A = 3.14 * (324)^2 = 329.624.64

Round the answer to at least three decimal places. A 9896 confidence interval for the proportion of all entering freshmen at this college who scored more than 590 on the math SAT IS 0.283

Answers

The 98% confidence interval for the proportion of all entering freshmen at this college who scored more than 590 on the math SAT is approximately 0.283 to 0.493.

To find the point estimate for the proportion of all entering freshmen at this college who scored more than 590 on the math SAT, we divide the number of freshmen who scored more than 590 by the total sample size.

Point Estimate = Number of freshmen who scored more than 590 / Total sample size

In this case, the number of freshmen who scored more than 590 on the math SAT is 45, and the total sample size is 116.

Point Estimate = 45 / 116 ≈ 0.388

Rounded to three decimal places, the point estimate for the proportion of all entering freshmen at this college who scored more than 590 on the math SAT is approximately 0.388.

To construct a 98% confidence interval for the proportion of all entering freshmen at this college who scored more than 590 on the math SAT, we can use the following formula:

Confidence Interval = Point Estimate ± (Critical Value * Standard Error)

The critical value corresponds to the desired confidence level and is obtained from the standard normal distribution. For a 98% confidence level, the critical value is approximately 2.326.

The standard error can be calculated using the following formula:

Standard Error = sqrt((Point Estimate * (1 - Point Estimate)) / Sample Size)

Using the point estimate from part (a) as 0.388 and the sample size as 116, we can calculate the standard error:

Standard Error = sqrt((0.388 * (1 - 0.388)) / 116) ≈ 0.050

Now we can construct the confidence interval:

Confidence Interval = 0.388 ± (2.326 * 0.050)

Lower Bound = 0.388 - (2.326 * 0.050) ≈ 0.283

Upper Bound = 0.388 + (2.326 * 0.050) ≈ 0.493

Rounded to three decimal places, the 98% confidence interval for the proportion of all entering freshmen at this college who scored more than 590 on the math SAT is approximately 0.283 to 0.493.

Based on the table, the linear equation that represents the change in water’s boiling point for every 1,000-foot change in altitude has a slope of
units.

Answers

The linear equation that represents the change in water’s boiling point for every 1,000-foot change is y = -1.8x + 212.

We have,

From the table,

Take two ordered pairs.

(0, 212) and (0.5, 211.1)

Now,

The slope can be calculated as,

= (211.1 - 212) / (0.5 - 0)

= -0.9/0.5

= -1.8

Now,

The equation can be written as,

y = mx + c

(0, 212) = (x, y)

So,

212 = -1.8 x 0 + c

c = 212

Now,

y = mx + c

y = -1.8x + 212

Thus,

The linear equation that represents the change in water’s boiling point for every 1,000-foot change is y = -1.8x + 212.
