First what your gonna do is find the slope. So y2-y1/x2-x1 so 17-12/220-120= 5/100 so 1/20. Then you have to put that into slope intercept form. So y=1/20x + b. Then plug in points for x and y. I’ll use 12 and 120. So 12 = 1/20(120)+ b = 12=6+b then subtract 6 from both sides to get b= 6. So your answer is y= 1/20x +6

Marina CMI [18]

Answer:

16

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

y(y² + 4y + 16) - 4x(y² + 4y + 16) ← distribute both parenthesis

= y³ + 4y² + 16y - 4xy² - 16xy - 64x

Compare - axy to - 16xy ⇒ a = 16

About 7% of the population has a particular genetic mutation. 400 people are randomly selected. Find the standard deviation for
Deffense [45]

Answer:

5.10 people

Step-by-step explanation:

Calculation to Find the standard deviation for the number of people with the genetic mutation

Using this formula

Standard deviation = √ ( n * p * q)

Where,

n = 400

p = .07

q = 100%-7% = 93% or .93

Let plug in the formula

Standard deviation =√400*07*.93

Standard deviation =√26.04

Standard deviation = 5.10 people

Therefore the standard deviation for the number of people with the genetic mutation is 5.10 people.
