From the table, the experimental Probability of rolling a 1 = 28/200 = 7/50
So for 25 rolls we would expect 7 * 25 / 50 = 3.5
answer: 4 times
To solve for x
x+7y=-4
x=-4-7y
Answer:
STOOPID
Step-by-step explanation:
(1/8), (2/8), (3/8), (4/8), (5/8), (6/8), (7/8)
if u want, 2/8=1/4, 4/8=1/2, 6/8=3/4
Answer:
153.158 ; 177.642
Step-by-step explanation:
Given the following:
Sample mean (m) = 165.40
Sample standard deviation (s) = 21.70
Sample size (n) = 17
α = 98%
Confidence interval = m ± z(SE)
z at 98% = 2.326
SE = s/√n
SE = 21.70/√17 = 5.2630230
Hence,
Confidence interval = 165.40 ± 2.326(5.2630230)
165.40 - 12.241791498 OR 165.40 + 12.241791498
153.158 ; 177.642
