Answer:
77 C
Step-by-step explanation:
To find the mean add all the numbers together then divide by the total amount of numbers
39 x 10
= 390
39 x 40 (390 x 4)
= 1,560
39 x 2
= 78
1,560 - 78
= 1,482
ANSWER: 1,482
Answer:
On the graphing calculator, use the function normCdf, where
- lower bound = -9999
- upper bound = 210
- mean = 250
- standard deviation = 46
It will result in normCdf(-9999,210,250,46) ≈ 0.192269 or 19.2269%
