Engineers want to design seats in commercial aircraft so that they are wide enough to fit 9090​% of all males.​ (accommodating 1
Andru [333]

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

Marya wants to factor the polynomial 36x3 – 22x2 – 144x. Which term can she add to the polynomial that would not change its grea
Aleksandr-060686 [28]

answer : -50xy\ and\ -40x^2

We find greatest common factor for the given polynomial

The prime factors of 36x^3 = 3 * 2 * 3* 2 * x *x *x

The prime factors of -22x^2 = -2 * 11 * x* x

The prime factors of -144x = -2 * 3 * 2 * 2 * 3 * 2 * x

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

-50xy\ and\ -40x^2 she can add to the polynomial that would not change its greatest common factor 2x.
