Answer:
0.28 = (76 - 103)/σ (B)
Step-by-step explanation:
Let X be a random variable for capturing moths every night
Mean(μ) = 103
σ is the standard deviation
Pr(X<76) = 28%
Pr(X<76) = 0.28
For normal distribution, Z = (X - μ)/σ
Pr(X<76) = (X - μ)/σ
0.28 = (76 - 103)/σ
The equation to find the standard deviation is
0.28 = (76 - 103)/σ
I think the best answer would be answer D
Slope formula:
m = y2 - y1 / x2 - x1
Line QR: (2,8) (3,10)
m = 10 - 8 / 3 - 2 = 2 / 1 = 2
Line ST: (0,6) (-2,2)
m = 2 - 6 / -2 - 0 = -4/-2 = 2
