Answer:

Step-by-step explanation:

1) Find the Mean of all the numbers.

3+4+5+7+10+12+15=56

56/7=8 mean is 8

Now We Calculate Standard Deviation:

S= $\sqrt{(3-8)^2+(4-8)^2+(5-8)^2+(7-8)^2+(10-8)^2+(12-8)^2+(15-8)^2}$

You take each number from the problem i.e 3,4,5...

and then you subtract the mean from it and then square it.

S= $\sqrt{(-5)^2+(-4)^2+(-3)^2+(-1)^2+(2)^2+(4)^2+(7)^2}$

S= $\sqrt{25+16+9+1+4+16+49}$

S= $\sqrt{120}$

S= $\sqrt{120}/7$

7 is the amount of data units given in the problem.

120/7=17.1428571429

$\sqrt{17.1428571429}$ =4.1403933560541

a section in a stained glass window is shaped like a trapezoid. The top base is 4 centimeters and the bottom base is 2.5 centime

dem82 [27]

Hello, so the equation for the area of a trapezoid is A = (a+b)*(h/2)

In which, a is one of the bases, b is the other base, and h is the height. A is the Area. If you wanna solve for height, rearrange the equation to what h equals.

First divide (a+b) from both sides
A/(a+b) = h/2

Now multiply 2 on both sides

2(A/(a+b)) = h

Now you have it rearranged equal to just h. Plug in the values now.

2(3.9/(4+2.5)) = h

2(3.9/(6.5)) = h

2(.6) = h

1.2 = h

The section is 1.2 centimeters tall.
