Answer:
y₂ = 3
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to - 
m = 
with (x₁, y₁ ) = (7, - 6) and (x₂, y₂ ) = (- 5, y₂ )
m =
, that is
= -
( cross- multiply )
4(y₂ + 6) = 36 ( divide both sides by 4 )
y₂ + 6 = 9 ( subtract 6 from both sides )
y₂ = 3

Answer:
0.815
Step-by-step explanation:
First, find the z-scores.
z = (x − μ) / σ
z₁ = (8 − 10) / 1
z₁ = -2
z₂ = (11 − 10) / 1
z₂ = 1
P(-2 < Z < 1) = P(Z < 1) − P(Z < -2)
Use a chart, calculator, or the empirical rule to find the probability.
Using the empirical rule:
P(-2 < Z < 1) = 0.84 − 0.025
P(-2 < Z < 1) = 0.815
Using a chart:
P(-2 < Z < 1) = 0.8413 − 0.0228
P(-2 < Z < 1) = 0.8185
