4 0

Answer:

Radius = 7.995944341

Step-by-step explanation:

You use the circumference formula. C=2πr

Since you have the circumference 50.24 cm. You plug in the circumference.

50.24 = 2πr

You divide by 2 and get 25.12.

25.12 = πr

Then, you divide 25.12 by π.

Your answer is

7.995944341 = r

marishachu [46]

Answer:

If David were summarizing the data from his sample, he would use Descriptive statistics. If he wanted to know whether or not his sample results could be generalized to the population, he would use Hypothesis testing statistics.

Step-by-step explanation:

Hello!

There are two types of statistics.

1. Descriptive statistics.

This method allows you to summarize the observed data of a sample, it gives you an idea of the data distribution shape, its variability, most common values, etc... You can summarize the data using numerical measures (for example: mean, median, mode, variance) or graphics (for example histogram, scatterplots, boxplots)

2. Hypothesis testing.

Using this method you can test the results of an experiment, using the previously summarized sample data, and reach a valid conclusion over your claims that can be generalized to the population of study afterward.

I hope it helps!

The cost (c) to hire a dog trainer is varies directly with the amount of time (h) in hours spent training the dog.
NNADVOKAT [17]

Answer:

Part A) The proportional equation is c=55h

Part B) 8 hours of training

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Let

c -----> the cost to hire a dog

h ----> the amount of time in hours

The linear equation is equal to

c=kh

Sue spent $660 on 12 hours of obedience training for her dog Muffin

Find the value of k (constant of proportionality)

k=y/x

substitute the values

k=660/12=55

therefore

The linear equation is

c=55h

For c=\$440

Find the value of h

substitute in the equation and solve for h

440=55h

h=440/55=8\ hours
