Let X be the hip breadth for men. X follows Normal distribution with mean μ =14.8 and standard deviation σ =1.1
Here we have to find the hip breadth for men that separates the smallest 90% from the largest 10%
That is we have to find X that separates lower 90% area from upper 10%. For that we will first find z such that probability below it is 0.9 and above it 0.1
P(Z < z) =0.9
Using z score table to find z value
We do not have probability value exactly 0.9 so we will take probability close to 0.9 which is 0.8997 and corresponding z score is 1.28
So we have P(Z < 1.28) =0.9
Now using z=1.28, μ =14.8 and σ =1.1 we will find value of x
x = z*σ + μ
= (1.28 * 1.1) + 14.8
x = 16.208 rounding to nearest integer x= 16
The hip breadth that separates lower 90% area from upper 10% is 16 inch
Answer:
The x axis is horizontal (sideways) while the y axis is vertical (up and down)
Step-by-step explanation:
answer :
We find greatest common factor for the given polynomial
The prime factors of
The prime factors of
The prime factors of
the greatest common factor of the terms 36x³ - 22x² - 144x is 2x
Now we check the options that has common factor 2x
–11 = -11
–50xy = - 2* 5 * 5 * x * y that has factor 2x
–40x^2 = -2 * 2 * 5 * 2 * x * x that has factor 2x
24 = 3 * 2 * 6
10y= 5 * 2 * y
she can add to the polynomial that would not change its greatest common factor 2x.
