Answer:
0.033 is the probability that a teenage boy has a cholesterol level greater than 225.
Step-by-step explanation:
The following information is missing in the question:
Mean, μ = 170
Standard Deviation, σ = 30
Using the given information, we may solve the question as:
We are given that the distribution of distribution of cholesterol levels in teenage boys is a bell shaped distribution that is a normal distribution.
Formula:
a) P( cholesterol level greater than 225)
P(x > 225)
Calculation the value from standard normal z table, we have,
0.033 is the probability that a teenage boy has a cholesterol level greater than 225.
2x+y=-6 the equation has to be in slope form (y=mx+b) the first thing that you have to do is find the slope which you can do fairly easy by moving the 2x to the other side of the equation. Y=-2x-1 then you use that slope and use a different y intercept for the two lines to be parallel
