Find the area and circumference of each circle.
ale4655 [162]

Area = πr^2

Circumference = 2πr

Blue:

Area = 5^2 = 25π

Circumference = 2 * 5 * π = 10π

Pink:

Area = 6^2 = 36π

Circumference = 2 *6*π = 12π

White:

r = 3

Area = 3^2 = 9π

Circumference = 2 *3 = 6π

Red:

Area = 7^2 = 49π

Circumference = 2 *7 = 14π

A random sample of 10 employees of a company was selected to estimate the mean one-way commute time for all employees at the com
liberstina [14]

Answer:

The margin of error is of 2.262\frac{6}{\sqrt{10}} = 4.29

Step-by-step explanation:

We have the standard deviation for the sample. So the T-distribution is used 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 = 10 - 1 = 9

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.95}{2} = 0.975. So we have T = 2.262

The margin of error is:

M = T\frac{s}{\sqrt{n}} = 2.262\frac{6}{\sqrt{10}} = 4.29

In which s is the standard deviation of the sample and n is the size of the sample.

Emilio has 8 large bottles of soda and 12 large jugs of water. Emilio wants to set up identical tables and have no drinks left o
masya89 [10]

Answer:

4

Step-by-step explanation:

Think about the ratio between the current number of large bottles of soda(8) and the current number of jugs of water (12)

By finding the GCF (Greatest Common Factor) of the two numbers, we can conclude that if both numbers were to be divided by the GCF, 4, we would get a 2:3 ratio.

For every 2 bottles of soda, 3 jugs of water will be placed. Keep doing this until we run out of both sources of liquid, in this case, 4 tables where we would use all the bottles of soda and the jugs of water.
