A stadium manager recorded the number of ticket resellers he noticed on various game days. He recorded the number of
resellers, x, during each day. The number of resellers observed
was normally distributed with a mean of 12 and a standard
deviation of 7.6.
Find the probability P of seeing at least 5 resellers during a
day. Round your answer to the nearest thousandth (using a z-
score rounded to the nearest tenth).

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
