Scores on a certain intelligence test for children between ages 13 and 15 years are approximately normally distributed with μ=106 and σ=15. (a) what proportion of children aged 13 to 15 years old have scores on this test above 92 ? (reminder: proportions are between 0 and 1 - don't put in percentages! )

5.762159

step-by-step explanation:

it would be 9 because when it is the nine is over five so that would mean it rounds up to 90 or 9

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .
