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.
Um sorry but i think your missing some info! reply to me and i can help with a question
Step-by-step explanation:
option A is correct
as, point S lies on = -7, 4
and point T lies on = 5, 4
so, diameter is 12 so radius = diameter/2 = 12/2 = 6
and center is - 1 , 4 as the diameter lies on 4 in y axis
hope this answer helps you dear...take care and may u have a great day ahead...also may ur exam/test/assignment goes well!.
Given:
Consider the dimensions of the rectangle are and .
To find:
The perimeter in terms of x, of the rectangle.
Solution:
Let the length of the rectangle be and the width of the rectangle is units.
The perimeter of a rectangle is:
Where, l is the length and w is the width of the rectangle.
Substituting and in the above formula, we get
Therefore, the perimeter of the rectangle is units.
