C = pi×diameter  OR C = 2pi×radius
So...
17.8 = pi×diameter    17.8 = 2pi×radius
17.8/pi = diameter      17.8/2pi = radius
<span>5.66591597407 = diameter or d
</span><span>2.83295798704 = radius or r</span>

What is the mean of the following data values?<br> 22, 37, 49, 15, 92
attashe74 [19]

Answer:

43

Step-by-step explanation:

First, you have to add 22+37+49+15+92 to get 215. To find the mean, you need to divide by how much numbers there are (5).  So 215 divided by 5 is 43!

A set of physics exam scores are normally distributed with a mean of 80 points and a standard deviation of 6
Anuta_ua [19.1K]

Answer:

The proportion of exam scores that are lower than Irina's score is 0.9938

Step-by-step explanation:

<u>Data</u>

  • mean: 80 points
  • standard deviation (sd): 6 points
  • value of interest (x): 95 points

z-score is computed as follows:

z = (x - mean)/sd

z = (95 - 80)/6 = 2.5

We want to find:

P(z < 2.5)

From the table attached:

P(z < 2.5) = 0.9938

Can someone help me find the equation for this line please
pogonyaev

Answer:

y = x + 1

Step-by-step explanation:

The line y = x  goes through the origin, and forms a perfect 45 degree angle with the x axis.

This is that same line, moved upward 1 unit, so the y value comes out 1 unit more.

Also, in y = mx + b form (slope-intercept form), we see slope m = 1 and y-intercept b = 1, so

y = 1x + 1 = x + 1

y = x + 1
