The lengths of plate glass parts are measured to the nearest tenth of a millimeter. The lengths are uniformly distributed with v

alues at every tenth of a millimeter starting at 590.2, and continuing through 590.8. Determine the mean and variance of the lengths. (a) mean (in tenths of millimeters) Round your answer to two decimal places (e.g. 98.76). (b) variance (in tenths of millimeters2) Round your answer to three decimal places (e.g. 98.765).

Answer:     \text{Mean length}=590.5\ mm\\\\\text{Variance of the lengths}=0.03\ mm

Step-by-step explanation:

The mean and variance of a continuous uniform distribution function with parameters m and n is given by :-

\text{Mean=}\dfrac{m+n}{2}\\\\\text{Variance}=\dfrac{(n-m)^2}{12}

Given : m=590.2\ \ \ n=590.80

\text{Then, Mean=}\dfrac{590.2+590.8}{2}=590.5\ mm\\\\\text{Variance}=\dfrac{(590.8-590.2)^2}{12}=0.03\ mm

Suppose a kite has diagonals of 10 and 20. Find the perimeter of the quadrilateral formed
Sonbull [250]
I think you can only say that the width of the quadrilateral  will be 5.

OH no  it will be a rectangle and the length will be 1/2 * 20 = 10

so the perimeter is 2*5 + 2*10  = 30 <---- answer

Circle B has a radius of 7.2in. Find the diameter of circle B dilated by a factor of 8.1
Helen [10]
Since the scale factor is greater than 1, this dilation will be an enlargement. Therefore, you multiply 7.2 times 8.1 to get 58.32. This question asks for diameter, so multiply 58.32 times 2 to get 116.64 in.

If angle X has a measure of 40 degrees and angle Y is vertical to angle X what is the measure of angle Y?
erica [24]
If an angle is 70 degrees and there is an angle vertical to it, then that other angle also equals 70 degrees. Therefore, if angle X equals 40 degrees, then angle Y also equals 40 degrees. Hope this helps.
