Using the normal distribution, it is found that the prediction is that the largest number of people would receive an IQ score of 100 on that test.
<h3>Normal Probability Distribution</h3>The z-score of a measure X of a normally distributed variable with mean and standard deviation
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
IQ scores have mean of 100, and since in the normal distribution most measures are around the mean, an IQ score of 100 is the prediction.

Answer:
5600 square feet is the area.
Step-by-step explanation:
Perimeter will be = 300 feet
Length of the fence enclosure must be at least 80 feet.
Width of the fence enclosure must be at least 40 feet.
Let x be the length and y be the width of the court.
We get following constraints:
If we calculate the area, we get
And for the perimeter we get:
⇒
Now look at the graph attached, we get point (80,70) as the possible solution.
So, the maximum area occurs when the dimensions are 80 feet by 70 feet.
