The mean length of six-year-old rainbow trout in the arolik river in alaska is 481 millimeters with a standard deviation of 41 millimeters. assume these lengths are normally distributed. what proportion of six-year-old rainbow trout are less than 516 millimeters long?

0.8023

Step-by-step explanation:

Given :

Assuming these lengths are normally distributed.

The formula to calculate the z-score is given by :-

For x=

The p-value =

Hence, the required probability : 0.8023

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
