Answer:
d/2=r
Step-by-step explanation:
radius is half the diameter
The nearest one hundred would be 1000.
Hope this helps!!
Variable A is x. Variable B is y. (x,y)
2 , 2, 4, 5, 6, 7, 8, 9
Mean is computed by adding all the numbers in the data set and dividing it by its count.
2 + 2 + 4 + 5 + 6 + 7 + 8 + 9 = 43
43 / 8 = 5.375 rounded to 5.4
SOLUTION
From the given data the mean is 62 and standard deviation is 4
It is required to find the probability that a data value is between 57 and 62
That is:

The z scores is calculated using:

Using the x values it follows:

Also,

Thus the required probability is:
![P(-1.25The proability is:[tex]P(-1.25This can be expressed as percentage as:[tex]P(-1.25\lt z\lt0.75)=66.8\%](https://tex.z-dn.net/?f=P%28-1.25The%20proability%20is%3A%5Btex%5DP%28-1.25This%20can%20be%20expressed%20as%20percentage%20as%3A%5Btex%5DP%28-1.25%5Clt%20z%5Clt0.75%29%3D66.8%5C%25)
Therefore the correct option is C
