Answer:
Option 3 and 4.
Step-by-step explanation:
The z score shows by how many standard deviations the raw score is above or below the mean. The z score is given by:

Given that mean (μ) = 82, standard deviation (σ) = 5
1) For x = 74:

Option 1 is incorrect
2) For x < 87

From the normal distribution table, P(x < 87) = P(z < 1) = 0.8413 = 84.13%
Option 2 is incorrect
3) For x = 95:

Option 3 is correct
4) For x < 77

From the normal distribution table, P(x < 77) = P(z < -1) = 0.16 = 16%
Option 4 is correct
5) For x > 92

From the normal distribution table, P(x > 92) = P(z > 2) = 1 - P(z < -2) = 1 - 0.9772 = 0.0228 = 2.28%
Option 5 is incorrect
Answer:
325
Step-by-step explanation:
Just add the number of kids who like chocolate, 175 to the number of kids of like pistachio, 150, and you get 325 children
For the answer to the question above,
Let's use the formula for finding the volume.
(pi) x 2/9 x 2/9 x r^2
(pi) x <u>2</u> x <u>2</u> x r^ 2 x 4h
9 9
simplify and solve.
The the will be
<u>16 </u>(pi) r^2h
81
I hope I helped you in my answer
