EXPLANATION

Since the circumference of the circle is 9.42, we can get the diameter by applying the following relationship:

$Circumference=2\pi r=2\pi\frac{d}{2}=\pi d$

Isolating the diameter:

$Diameter=\frac{Circumference}{\pi}$

Plugging in the numbers:

$Diameter=\frac{9.42}{3.14}=3$

Therefore, the diameter is equal to 3 inches.

C= 12r + 2 what is C? What is r?

postnew [5]

Answer:

Unless there is some context behind it, with a picture or something here you are.

Step-by-step explanation:

C=12r+2

So, we have to find out what it could be.

You can plug in anything for r, so I'll make it easy.

r=1

C=12*(1)+2

12*1=12+2=14

C=14.

Find the value of x given in the right triangle

ladessa [460]

Answer:

The formula for this is $c=a^2+b^2$

The value of x would be 7.14 but since it says round to the nearest tenth it would be 7.1 or 7.10

According to a survey of workers, 5/25 of them walk to work, 1/25 bike, 4/25 carpool, and 15/25 drive alone. What percent of wor

KATRIN_1 [288]

Answer: 24%

Step-by-step explanation:

First add up the proportion of people who walk to work and those who bike as well. This will show the proportion of people who walk or bike to work.

This is:

= 5/25 + 1/25

= 6/25

Then convert this to a percentage:

= 6/25 * 100

= 24%

Scoring a hole-in-one is the greatest shot a golfer can make. Once 5 professional golfers each made holes-in-one on the 7th hole

adell [148]

A) Probability that at least one of these golfers makes a hole in one on the 10th hole at the same tournament is

=1−(2493/2494)^5
=1-(0.99)^5
= 1- 0.96
=0.4

b) The probability that all of these golfers make a hole-in-one on the 10th hole at the same tournament
=(1/2494)5

which is nearly zero.

A sport statistician gathered data on the number of points scored in each game by high school basketball players across the coun

Sonbull [250]

For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98

<h3>What is a sample size?</h3>

The sample size is a term used in market research for defining the number of subjects included in a sample size. By sample size, we understand a group of subjects that are selected from the general population and is considered a representative of the real population for that specific study.

Empirical rule states that for a normal distribution, 68% of the values are within one standard deviation from the mean, 95% of the values are within two standard deviation from the mean and 99.7% of the values are within three standard deviation from the mean.

For a population mean of 20.15 and a standard deviation of 3.7

68% are within μ ± σ/√n,

hence,

68% = 20.15 ± 3.7/√20 = (19.32, 20.98)

For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98.
