The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h. A=1/2h(a+b) Solve for h.
Gnom [1K]
Given the formular for relating the <span>area A, the two bases, a and b, and the height, h</span> of a trapezoid is given by

A= \frac{1}{2}h (a+b)

We solve for h as follows:

A= \frac{1}{2}h (a+b) \\  \\ \Rightarrow2A=h (a+b) \\  \\ \Rightarrow h= \frac{2A}{a+b}

Eddi Din [679]

Answer: 0.547

Step-by-step explanation:

As per given , we have

Population mean = \mu=20

Population standard deviation= \sigma=4

Sample size : n= 36

We assume that number of apps used per month by smartphone owners is normally distributed.

Let \overline{x} be the sample mean.

Formula : z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

The probability that the sample mean is between 19.5 and 20.5 :-

P(19.5

[using standard normal distribution table for z]

Hence, the required probability = 0.547
