Answer:

13 subs will serve 52 people.

Step-by-step explanation:

We are given the following information in the question:

Number of subs: 3 5 8

People served: 12 20 32

We have to find that how many people with be served by 13 subs.

We can solve this question with the help of ratio.

$\text{Ratio} = \displaystyle\frac{\text{Number of subs}}{\text{People served}}\\\\= \frac{3}{12} = \frac{1}{4}$

The obtained ratio is 1:4, which means that 1 sub can serve 4 peoples.

Let x be the number of people served by 13 subs:

$\displaystyle\frac{1}{4} = \frac{13}{x}\\\\\Rightarrow x = \frac{13\times 4}{1} = 52$

Hence, 13 subs will serve 52 people.

I think its 44. The amount of people increase by 12 every time you add more subs. Hope that helps!

Which sampling method is MOST appropriate in estimating the average number of votes for each candidate in an election across a c

kaheart [24]

Answer:

B. Stratified sampling, because there are specific subgroups to investigate.

Step-by-step explanation:

Stratified Sampling is a sampling method and is used when the population has subgroups with different characteristics. Random sampling is applied in each of the sub-groups <em>proportional </em>to their size and then these samples <em>combined </em>together to create sample of the study.

Since there are three towns with people from different occupations ( retirees,business owners, office workers), it is better to use stratified sampling method.

You're standing on the ground 7777 meters away from the bottom of a tall tower. The tower itself is 346346 meters tall. What is

lys-0071 [83]

Answer:

88.7°

Step-by-step explanation:

First, visualize. Assuming that the tower is at a perfectly 90° angle to the ground, you have a right triangle. We will call this triangle ΔABC where A is where you are, B is the top of the tower, and C is the base of the tower. Now we know the following:

∠A = ?

∠B = ?

∠C = 90

a = 346346

b = 7777

c = ?

Note: Triangles are labeled with three pairs of letters: a, b and c and A, B and C. The lower case letters, a, b and c represent the sides, and the upper case letters are the angles that are directly opposite of those sides. (see attached reference)

c is easy, c is the hypotenuse, so you can use the following equation to find the hypotenuse:

a² + b² = c²

Rearranged:

c = ± $\sqrt{a^{2} +b^{2} }$
