Answer:

y = 300 (2)^x

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

x = 66 minutes *\frac{1period}{22 minutes}= 3

So then we need to replace the value of x =3 and we got:

y= 300 (2)^3 = 2400

Step-by-step explanation:

For this case we have the following function:

y = 300 (2)^x

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

x = 66 minutes *\frac{1period}{22 minutes}= 3

So then we need to replace the value of x =3 and we got:

y= 300 (2)^3 = 2400

A 10-foot ladder leans against a wall. It hits the wall 9 feet up. How far is the base of the ladder from the wall? Apply the Pythagorean Theorem to this problem

triangle

side S1 = 9 feet

hypotenuse H = 10 feet

side S2 - X = ?

the Pythagorean Theorem

H x H = S1 x S1 + S2 x S2 = S1 x S1 + X x X

X x X = H x H - S1 x S1 = 10 x 10 - 9 x 9 = 100 - 91 = 9

X x X = 9

X = 3

How far is the base of the ladder from the wall? 3 feet

check:

H x H = S1 x S1 + X x X

10 x 10 = 9 x 9 + 3 x 3

100 = 91 +9 = 100

Determine whether the selection process for each sample was random or nonrandom.
stepladder [879]

The selection process for each sample was Random, Hence, Random sampling

This is further explained below.

<h3>Determine whether the selection process for each sample was random or nonrandom.?</h3>

Generally,  During physical education classes, students are randomly assigned to teams by selecting names from a hat or bag containing their names on individual pieces of paper.

There is a designated area at a supermarket for shoppers to leave comments. Each week, a satisfied customer will be randomly selected from the feedback forms submitted to win a gift certificate.

Selection bias

For a research project, physicians must first compile a list of patients. The first ten people on the list will be placed in the placebo group.

A clothes retailer conducts surveys of clients who use its store credit card to better understand its clientele.

We collect five soil samples from the biggest farm in a given area to determine the quality of the soil there.

The distinction between random and non-random sampling is explained.

In random sampling, each sample has the same chance of getting the target variable. When a researcher uses a sampling strategy that is not random, the features of the sample chosen are not based on chance but on factors like their own convenience, their own professional judgment, and their own prior experience.

In conclusion,  During physical education classes, students are randomly assigned to teams by selecting names from a hat or bag containing their names on individual pieces of paper.

There is a designated area at a supermarket for shoppers to leave comments. Each week, a satisfied customer will be randomly selected from the feedback forms submitted to win a gift certificate.

at the party 2/5 of the pizzas ordered had pepperoni .The kids ate only 1/3 of the pepperoni pizzas, while the parents ate all o
kodGreya [7K]
Here is the solution for the given problem above.
Given that in the whole pizza, 2/5 of it is pepperoni (which makes 3/5 of the pizza has different flavor). What we are going to find is how much of all the pizza ordered was eaten by the kids, since only 1/3 of the pepperoni pizza is eaten by them. So to solve this, we will multiply 1/3 by 2/5 and the answer would be 2/15. Therefore, the answer is 2/15 of the pizza was eaten by the kids.
