<h2>Given:-</h2>
y = 2x + 50
x = 5
So,
y = 2(5) + 50
y = 10 + 50
y = 60
Hence, option B, y = 60, is correct.

2×3×3×3=54
Answer:
Option A - 4.91
Step-by-step explanation:
The formula for theoretical standard deviation of uniform distribution is;
σ = √{(b-a)^2}/12
Now from the question, b = 38 minutes and a= 21 minutes
Therefore, σ = √{(38-21)^2}/12
= √{17^2}/12 = √289/12 = 4.907 which is approximately 4.91
Wouldn’t the answer be 40 be cause you multiply?
