A blologist is studying rainbow trout that live in a certain river and she estimates their mean length to be 504 millimeters. Assume that the lengths of these rainbow trout are normally distributed, with a standard deviation of 84 millimeters.
Use this table or the ALEKS calculator to find the percentage of rainbow trout in the river that are longer than 483 millimeters. For your intermediate
computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%).

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

step-by-step explanation:

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
