We first determine the z-scores for the given x-values of 64 and 96.
For x = 64: z = (64 - 80) / 8 = -2
For x = 96: z = (96 - 80) / 8 = 2
Therefore we find the probability that -2 < z < 2, which is around 0.95. Therefore, out of 100 students, approximately 100(0.95) = 95 students will weigh between 64 and 96 pounds.
Add 2 hundreds and you get 370 then add 4 tens and get 410
The answer is 82 and your welcome
Answer:
arc = 9π units
Step-by-step explanation:
the arc is half the circumference of the circle, then
arc = × 2πr = πr , then
arc = π × 9 = 9π
