a) For x = 27:
z = 27-28/2 = -0.5
For x = 31:
z = 31-38/2 = 1.5
From the normal distribution table, P(27 < x < 31) = P(-0.5 < z < 1.5) = P(z < 1.5) - P(z < -0.5) = 0.9332 - 0.3085 = 62.47%
b) For x > 30.2:
z = 30.2-28/2 = 1.1
From the normal distribution table, P(x > 30.2) = P(z > 1.1) = 1 - P(z > 1.1) = 1 - 0.8643 = 13.57%
21 is 25% of 84
21 • 4 = 84
You can check this answer by take 25% of 84.
84 • 0.25 = 21
Answer: C
Step-by-step explanation:
Answer:
I believe it's linear
Step-by-step explanation:
don't quote me on that tho
Since 5/12 equal 0.4166666666...., so then 6 + 0.4166666666.... = 6.4166666666.... ., so 6 5/12 equals 6.4166666666666666........
Hope I'm the brainliest!!!!!
