SOLUTION:
A normal distribution would model this situation because the distribution is approximately symmetrical, thus the mean, median and mode are approximately the same and the population size is large ( greater than 30).
Answer: 70
Step-by-step explanation:
a^2 + b^2 = c^2
24^2 + b^2 = 74^2
576 + b^2 = 5,476
-576 -576
b^2 =4,900
(square root)
b =70
Answer:
-3
Step-by-step explanation:
A negative plus a positive is like subtraction. But make sure you make your answer negative.
Part A: Square cross-section
Part B: Rectangle cross-section
Its b. Just draw it on graph paper. Its an easy estimate
