The volume of the prism is 195 cubic meters.

To find the volume of the prism, we need to multiply the length, width, and height of the prism.

Length = 13 m

Width = 3 m

Height = 5 m

Volume = Length x Width x Height

Volume = 13 m x 3 m x 5 m

Volume = 195 cubic meters

The test statistic is 14.5 and the P-value is less than 0.05. Therefore, we have evidence to suggest that the distribution of days of the week of the appointments disagrees with an Even distribution.

To carry out the chi-squared goodness-of-fit test, we need to calculate the expected number of appointments for each day if there were an even distribution. Since there are 5 days of the week, each day would have an expected value of 100 (i.e., 500 appointments / 5 days = 100 appointments per day).

Day | Monday | Tuesday | Wednesday | Thursday | Friday

Observed | 115 | 100 | 115 | 100 | 70

Expected | 100 | 100 | 100 | 100 | 100

To calculate the chi-squared test statistic, we use the formula:

χ2= ∑ (observed − expected)^2 / expected

Plugging in the observed and expected values, we get:

χ2= [(115 - 100)^2/100] + [(100 - 100)^2/100] + [(115 - 100)^2/100] + [(100 - 100)^2/100] + [(70 - 100)^2/100]

  = 2.75 + 0 + 2.75 + 0 + 9

  = 14.5

To find the P-value, we need to use the chi-squared distribution table with 4 degrees of freedom (5 days of the week minus 1 for the expected value). Using the table, we find that the P-value for a chi-squared statistic of 14.5 with 4 degrees of freedom is less than 0.05. Therefore, we reject the null hypothesis that the appointments have an even distribution from Monday through Friday.the test statistic is 14.5 and the P-value is less than 0.05. Therefore, we have evidence to suggest that the distribution of days of the week of the appointments disagrees with an even distribution.

Answer:

r = 7

Step-by-step explanation:

equation of circle is (x - a)² + (y - b)² = r²

where a is x-coordinate of centre of circle, b is y-coordinate of centre of circle, r is the radius. radius = half of diameter.

x² - 8x + y² - 10y = 8

we need to complete the sqaure for both x and y

x² - 8x = (x - 4)² = x² - 8x + 16, which is 16 more than x² - 8x. so we need to subtract that 16.

we now have (x - 4)² - 16.

now do the same with y

(y - 5)² = y² - 10y + 25, which is 25 more than y² - 10y. so we need to subtract 25.

we now have (y - 5)² - 25.

back to our full equation.

(x - 4)² -16 + (y - 5)² - 25 = 8

(x - 4)² + (y - 5)² - 41 = 8

(x - 4)² + (y + 5)² = 49 = r²

radius r = √49 = 7

There are a total of 15 good students, 35 weak and 40 in bad shape if number of good students are fraction of 1/6th of total students.

As we know that the total number of students are 90.

Good students are fraction of 1/6th of total students.

Good students= 1/6x90

Good students=15

There are 40 good students in a whole block, so X = 40.

In the whole grade, average number of students is 1/3 of students in whole grade.

Students in each class = 1/3x90

Students in each class = 30

Students who are not good in economics and government = 90-40

Students who are not good in economics and government = 50

As the total number of students is sum of good students and weak students.

15+Weak students =90-40

15+Weak students=50

Weak students=50-15

Weak students=35

Answer:

Perdón no te puedo ayudar no entiendo

Step-by-step explanation:

To find the average velocity of the particle over the interval [1, e], we need to calculate the net displacement divided by the time interval.

Given the position function x(t) = ln(t), let's find the displacement by evaluating x(e) and x(1):

x(e) = ln(e) = 1

x(1) = ln(1) = 0

So, the net displacement is 1 - 0 = 1.

The time interval is e - 1.

Therefore, the average velocity is:

average velocity = (net displacement) / (time interval)

average velocity = 1 / (e - 1)

The correct answer is B. 1/(e - 1).

All points that lie on the line that passes through point `P` and is perpendicular to line ' t' are: (4, -1) and (6, -5)

The equation of a line in slope intercept form is:

y = mx + c

where:

m is slope

c is y-intercept

Using two coordinates on line t as: (-4, 1) and (2, 4), the slope of the line t is:

Slope = (4 - 1)/(2 + 4)

Slope = 3/6

Slope = 1/2

Equation of line t is:

(y - 1)/(x + 4) = 1/2

y - 1 = x/2 + 2

y = ¹/₂x + 3

Thus, slope of line passing through P and perpendicular to t is: -1/(1/2) = -2

Now, coordinates of point P is (3, 1). Thus:

Equation passing through point P and perpendicular to line t is:

(y - 1)/(x - 3) = -2

y - 1 = -2x + 6

y = -2x + 7

The only coordinates that fits into this are (4, -1) and (6, -5)

The combined length of the two pieces of wire is 3/2 inches or 1 and 1/2 inches.

To find the combined length of the pieces of wire, we need to add the lengths of the two pieces of wire together.

The first piece of wire is 7/8 of an inch long.

The second piece of wire is 5/8 of an inch long.

To add the two fractions, we need to find a common denominator. The smallest number that both 8 and 5 will divide into is 40.

7/8 can be rewritten as 35/40 (multiply the numerator and denominator by 5)

5/8 can be rewritten as 25/40 (multiply the numerator and denominator by 5)

Now we can add the two fractions:

35/40 + 25/40 = 60/40

We cannot conclude that 95% of the population agrees that there is no difference in Taste between Coke and Pepsi.

To calculate the probability that 95% of the population agrees that there is no difference in taste between Coke and Pepsi, we can use the binomial distribution formula.

Let X be the number of students who say there is no difference in taste, and n be the total number of students in the sample. Then, X follows a binomial distribution with parameters n and p, where p is the true proportion of students who say there is no difference in taste.

The point estimate of p is 7/10 = 0.7. The standard error of the proportion can be calculated as the square root of p(1-p)/n = sqrt(0.7*0.3/10) = 0.23.

Using a normal approximation to the binomial distribution, the 95% confidence interval for p is given by:

0.7 +/- 1.96*0.23 = (0.24, 1.16)

Since the interval includes 0.5, which represents the point where the proportion of agreement and disagreement is equal, we cannot conclude that 95% of the population agrees that there is no difference in taste between Coke and Pepsi.

Inverse variation is a relationship between two variables where one variable increases as the other variable decreases, and vice versa.

This means that as one variable doubles, the other variable will decrease by half, or vice versa.

The following are situations that depict inverse variation:

1. When you are traveling at a constant speed, the time it takes to cover a given distance is inversely proportional to the distance. This is because the distance will decrease as the speed increases.

2. If you have a light source, the intensity of the light decreases as you move further away from the source. This is because the distance between the source and the object increases as the intensity of the light decreases.

3. The force of gravity between two objects is inversely proportional to the square of the distance between them. This is because the force of gravity will decrease as the distance between the objects increases.

4. When the temperature of a gas decreases, its pressure increases. This is because the volume of the gas remains constant as the temperature decreases, which causes the pressure to increase according to the gas laws.
