Second question

The area of a circle: area = pi * r^2

radius = diameter/2 = 94.2 in./2 = 47.1 in.

area = pi * r^2 = 3.14 * 47.1 in. * 47.1 in. = 6966 in.^2

Answer: 6966 in.^2

A psychologist wants to estimate the proportion of people in a population with IQ scores between 80 and 140. The IQ scores of th
ryzh [129]

Using the Empirical Rule, it is found that the proportion of people in a population with IQ scores between 80 and 140 is of 0.95 = 95%.

<h3>What does the Empirical Rule state?</h3>

It states that, for a normally distributed random variable:

  • Approximately 68% of the measures are within 1 standard deviation of the mean.
  • Approximately 95% of the measures are within 2 standard deviations of  the mean.
  • Approximately 99.7% of the measures are within 3 standard deviations of the mean.

Considering the mean of 110 and the standard deviation of 15, we have that:

  • 80 = 110 - 2 x 15.
  • 140 = 110 + 2 x 15.

These values are both the most extreme within 2 standard deviations of the mean, hence the proportion of people in a population with IQ scores between 80 and 140 is of 0.95 = 95%.

ki77a [65]

First, let's find the amount of calories in a 1 inch pizza:

570/6=95

Knowing this, we just multiply the calorie count of a one inch pizza by 14 to find the calorie count of a 14 inch pizza:

14*95=1330

There are 1330 calories in a 14 inch pizza.
