Answer:

169.646

Step-by-step explanation:

The equation for the surface area of a cylinder is $A=2\pi rh+2\pi rx^{2}$ . Plug in 3 for $r$ and 6 for $h$ to solve for surface area.

Answer:

$Min =120, Max= 150$

The first quartile can be calculated with this data:

130, 135, 140, 120, 130, 130

And the middle value is:

$Q_1 = \frac{140+120}{2}=130$

The median is the value in the 6th position from the dataset ordered and we got:

$Median= 135$

The third quartile can be calculated with this data:

135 140 140 143 144 150

And the middle value is:

$Q_3 = \frac{140+143}{2}=141.5$

The five number summary for this case:

Min. 1st Qu. Median Mean 3rd Qu. Max.

120.0 130.0 135.0 135.6 141.5 150.0

The boxplot is on the figure attached

Step-by-step explanation:

We have the following data given:

130, 135, 140, 120, 130, 130, 144, 143, 140, 130, 150

If we sort the values on increasing order we got:

120 130 130 130 130 135 140 140 143 144 150

The minimum and maximum are:

$Min =120, Max= 150$

The first quartile can be calculated with this data:

130, 135, 140, 120, 130, 130

And the middle value is:

$Q_1 = \frac{140+120}{2}=130$

The median is the value in the 6th position from the dataset ordered and we got:

$Median= 135$

The third quartile can be calculated with this data:

135 140 140 143 144 150

And the middle value is:

$Q_3 = \frac{140+143}{2}=141.5$

The five number summary for this case:

Min. 1st Qu. Median Mean 3rd Qu. Max.

120.0 130.0 135.0 135.6 141.5 150.0

Using the mean concept, it is found that the mean difference between the call times and the company's average call time is given by:

C. 0.4

The <em>mean </em>of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.

In this problem:

The four observations are the differences between the time of each phone call and the average time.

They are: {-2.32, -1.55, 4.79, 0.68}

Hence, the mean difference is:

$M = \frac{-2.32 - 1.55 + 4.79 + 0.68}{4} = 0.4$

Hence, option C is correct.

For his birthday, Mr. Robin and four of his friends went to a Math museum to learn about new intergalactic math. They each got a

Helen [10]

Answer: $10

Step-by-step explanation:

Given

Robin and his four friends bought tickets for $\$12$ each

If each one of them bought a calculator then the total spendings are $\$110$

Suppose the cost of each calculator is $\$\ x$

Cost per person is given by $x+\$12$

For the group, it is $5(x+12)$

Equate this to total spendings

$\Rightarrow 5(x+12)=110\\\Rightarrow x+12=22\\\Rightarrow x=\$\ 10$

thus, the cost of each calculator is $\$ 10$

How do you add a picture of a math problem on this app

Dominik [7]

Just save the picture of the math problem to your computer, then when u ask your question, u will see 3 buttions, click the paperclip button to upload the math problem and let it load, sometimes it will load, sometimes not, so ur going to have to click the edit button when your question is on the list, and than click the paperclip button again to upload it one more time and than it will work, u need to hurry up and do it b4 someone answers it and u wont be able to edit it.
