Time taken by a randomly selected applicant for a mortgage to fill out a certain form has a normal distribution with mean value
Natali [406]

Given:

z = (x - μ)/σ = z value
x = independent variable = 11
μ = mean = 8
σ = standard deviation = 3

Solution:

X ~ N (8, 3)

For day 1, n = 5

P (X < = 11) = P (Z < = 11 – 8 / 3/Sqrt5) = P (Z < =2.23) = 0.987126

For day 1, n = 6

P (X < = 11) = P (Z < = 11 – 8 / 3/sqrt6) = P (Z < =2.45) = 0.992857

 

For both days:

P (X <= 11) = P (X <= 11) = (0.987126) (0.992857) = 0.9801

Jason drew a scale drawing of a city. He used the scale 1 inch : 4 yards. A neighborhood park is 68 yards wide in real life. How
ra1l [238]

Answer:

  17 inches

Step-by-step explanation:

The scale is the same at every distance, so ...

  \dfrac{\text{1 in}}{\text{4 yd}}=\dfrac{w}{\text{68 yd}}\\\\\text{(1 in)}\dfrac{\text{68 yd}}{\text{4 yd}}=w \qquad\text{multiply by 68 yd}\\\\\text{17 in}=w

The park is 17 inches wide on the drawing.

Question 2 pls answer quickk
Otrada [13]

Answer:

Hey there!

First we find the slope: -3-0/10-4, or -3/6. That makes the slope -1/2.

Using point slope form we have-

y-0=-1/2(x-4)

y=-1/2x+2

Let me know if this helps, or if you need any more help :)
