Answer:
y=q(x-r)+p
Step-by-step explanation:
y-y1=m(x-x1)
y-p=q(x-r)
y=qx-qr+p
y=q(x-r)+p

Step-by-step explanation:
Answer:
0.1469
Step-by-step explanation:
Given from the question;
Mean=8.4 hrs=μ
Standard deviation=1.8 hrs=δ
Sample size, n=40
Let x=8.7
z=(x-μ)÷(δ÷√n)
Find z(8.7)
z=(8.7-8.4)÷(1.8÷√40)
z={0.3×√40}÷1.8=1.05409
z=1.0541
Read from the standard normal probabilities table
P(z>1.0541)
=0.1459
To calculate the distance between two points we use this formula:

<h3>______________________</h3>
<h3>We organize the values:</h3>
- x₁ = -5
- x₂ = -3
- y₁ = 8
- y₂ = 0
______________________
We apply the values already obtained to the formula to get the distance:

Round 31.9 up to 32 so you can divide it by 4 to get about 8.
