Step-by-step explanation:

The surface area of the cylinder, when the radius is 3 centimeters and the height is 4 centimeters, is approximately 131.88 square centimeters.

Use the provided formula for the surface area of a cylinder:

[tex]\[ SA = 2\pi r (h + r) \][/tex]

Given:

[tex]r = 3 \text{ centimeters}[/tex]

[tex]h = 4 \text{ centimeters}[/tex]

Now, substitute these values into the formula and calculate the surface area:

[tex]SA = 2\pi \times 3 \times (4 + 3)[/tex]

[tex]SA = 2\pi \times 3 \times 7[/tex]

[tex]SA = 6\pi \times 7[/tex]

[tex]SA = 42\pi[/tex]

Now, let's calculate the numerical value:

[tex]SA \approx 42 \times 3.14[/tex]

[tex]SA \approx 131.88 \text{ square centimeters}[/tex]

Therefore, the surface area of the cylinder, when the radius is 3 centimeters and the height is 4 centimeters, is approximately 131.88 square centimeters.

Answer:

-70

Step-by-step explanation:

40-8-102

= 32 - 102

= -70

To evaluate the expression 40 - 8 - 102, subtract 8 from 40 to get 32, then subtract 102 from 32 to arrive at -70.

40 - 8 - 102

To solve this expression, we need to follow the order of operations. In this case, since there are only subtraction operations involved, we can proceed from left to right.

40 - 8 = 32

32 - 102 = -70

This gives us the final answer: -70.

Answer:

We are 95% confident that the true weight of the rock is between 25.2 g and 29.1 g.

Step-by-step explanation:

Hello!

A geology student weighted a rock 5 times and estimated the average weight using a 95% CI [25.2; 29.1]gr

The confidence interval is used to estimate the value of the population mean, it gives you a range of values for it.

The 95% level of confidence of the interval indicates that if you were to construct 100 confidence intervals to estimate the population mean, you'd expect 95 of them to include the true value of the parameter.

So with a 95% confidence level, you'd expect the true average weight of the rock to be included in the interval  [25.2; 29.1]gr

Answer:

The margin of error for the mean is of 165.18 points.

Step-by-step explanation:

We have the standard deviation of the sample, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 81 - 1 = 80

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 80 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 1.9901

The margin of error is:

M = T*s = 1.9901*83 = 165.18.

In which s is the standard deviation of the sample.

The margin of error for the mean is of 165.18 points.

The answer discusses z-scores for SAT scores, calculating scores above the mean, and comparing performance on different tests.

Explanation:

Z-score for SAT score of 720:

Calculate the z-score: z = (720 - 520) / 115 = 1.74.

Interpretation: A score of 720 is 1.74 standard deviations above the mean.

Math SAT score 1.5 standard deviations above the mean:

Calculate the score: 520 + 1.5(115) ≈ 692.5.

The score of 692.5 is 1.5 standard deviations above the mean of 520.

Better performance on math tests:

For SAT: z = (700 - 514) / 117 ≈ 1.59.

For ACT: z = (30 - 21) / 5.3 ≈ 1.70.

Person with a z-score closer to 2 performed better relative to the test they took.

Final answer:

The probability of the spinner landing on an orange section is 1/4 or 0.25, meaning there is a 25% chance it will land on orange.

Explanation:

The question involves calculating the probability of a spinner landing on a specific color. If a spinner has 12 equal-sized sections and three of them are orange, to find the probability of landing on orange, we use the ratio of the number of orange sections to the total number of sections. In this case, there are 3 orange sections and 12 sections in total, so the probability (P) is:

P(orange) = Number of orange sections / Total number of sections

P(orange) = 3 / 12

P(orange) = 1 / 4

Therefore, the probability that the spinner will land on orange is 1/4 or 0.25, which means there's a 25% chance the spinner will land on an orange section.

Answer:

20 seconds

Step-by-step explanation:

The least common multiple of 4 and 5 is 20.  So the two lights will blink at the same time every 20 seconds.

Based on the number of seconds it takes for each light to blink, they will both blink at 20 seconds.

The green light blinks every 4 seconds and the yellow, every 5 seconds.

The time that they will blink together depends on the lowest common multiple of both numbers.

Multiples of 4 = 4, 8, 12, 16, 20

Multiples of 5 = 5, 10, 15, 20

The lowest common multiple is 20 which means they will blink together after 20 seconds.

System of hypothesis

we want to check if the true proportion for the college enrollment is higher thna 0.48, the system of hypothesis are:

Null hypothesis:[tex]p\leq 0.48[/tex]  

Alternative hypothesis:[tex]p > 0.48[/tex]  

The statistic is given by:

[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)  

Replacing the info given we have:

[tex]z=\frac{0.503-0.48}{\sqrt{\frac{0.48(1-0.48)}{700}}}=1.218[/tex]  

Now we can calculate the p value given by:

Answer:

$3,256.2

Step-by-step explanation:

First, we need to get 3% of 3,460. Find the decimal value of 3%:

3% -> [tex]\frac{3}{100}[/tex] -> 0.03

Next, lets multiply 3,460 by 0.03:

[tex]x=3,460(0.03)[/tex]

[tex]x=103.8[/tex]

Now subtract that number from 3,460:

[tex]3,460-103.8=3,356.2[/tex]

Lastly, lets take the $100 fee off of the number we just got:

[tex]3,356.2-100=3,256.2[/tex]

The new amount is $3,256.2

Answer:

3% fee is taken out of an initial amount of $3,460, and then a $100 fee is taken after that, leaving a new amount of $3,256.2.

Final answer:

Mrs. Golden will need 26 squares of silver paper to cover her bulletin board, and there will not be any pieces left over.

Explanation:

To find out how many 1-foot squares Mrs. Golden needs to cover her bulletin board, we first need to calculate the area of the bulletin board. The area of a rectangle can be found by multiplying the length and width. In this case, the length is 6.5 feet and the width is 4 feet, so the area is 6.5 feet x 4 feet = 26 square feet.

Since the silver paper comes in 1-foot squares, we can divide the area of the bulletin board by the area of each square to find out how many squares are needed. In this case, we divide 26 square feet by 1 square foot, giving us a result of 26 squares.

There will not be any pieces left over because 26 squares fully cover the area of the bulletin board. If there were any remaining space, we would need a fraction of a square to cover it.

Answer:

The slope of the line is 2.2 or 11/5

Step-by-step explanation:

I graphed the points on the graph below and found the slope of the line.

The slope of the line is 11/ 5.

The slope is equal to the change in y over the change in x, or rise over run.

m = change in y/change in x

The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).

m = (y₂−y₁)/(x₂−x₁)

Substituting the values of x and y into the equation to find the slope.

m = (5 − ( − 6 ))/(−4−(−9))

m =11/5

Therefore, the Slope of the line is 11/ 5.

Answer:an isosceles triangle cannot be an equilateral triangle

Step-by-step explanation:

An isosceles triangle cannot be an equilateral triangle

Final answer:

An isosceles triangle has at least 2 equal sides and an equilateral triangle has all sides equal. All equilateral triangles are isosceles triangles, but not all isosceles triangles are equilateral triangles.

Explanation:

An isosceles triangle has at least 2 equal sides, while an equilateral triangle has all sides equal. Therefore, the sentence 'All isosceles triangles are equilateral triangles' is not true because not all isosceles triangles have all sides equal. On the other hand, the sentence 'All equilateral triangles are isosceles triangles' is true because every equilateral triangle automatically has at least 2 equal sides. Furthermore, it is possible for an equilateral triangle to not be an isosceles triangle if all three sides are not equal in length. So, the sentence 'An isosceles triangle cannot be an equilateral triangle' is not true.

Answer:

10 green cubes

Step-by-step explanation:

The total number of cubes is 8+2+10 = 20

The probability of drawing a green cube when there is replacement is

P(green) = green cubes/ total

               =2/ 20

              = 1/10

Multiply the probability by the number of draws to get the total number of cubes

1/10 * 100 draws = 10 green cubes

Expect 10 green cube draws in 100 pulls, with 8 red and 10 blue cubes also present.

To calculate the expected number of times a green cube is drawn, we can use the concept of probability.

In each pull, there are 20 cubes in total (8 red + 2 green + 10 blue). So, the probability of drawing a green cube in a single pull is:

[tex]\[ P(\text{green}) = \frac{\text{number of green cubes}}{\text{total number of cubes}} = \frac{2}{20} = \frac{1}{10} \][/tex]

Since each pull is independent and the cubes are replaced after each pull, the probability of drawing a green cube remains the same for each pull.

Therefore, the expected number of times a green cube is drawn in 100 pulls is:

[tex]\[ \text{Expected number of green draws} = P(\text{green}) \times \text{Total number of pulls} = \frac{1}{10} \times 100 = 10 \][/tex]

So, you would expect them to draw a green cube about 10 times in 100 pulls.
