Answer:
B
Step-by-step explanation:
Answer:5
Step-by-step explanation:
27 chairs
5 tables
27/5
=5.4
It’s A. 10 feet is 10/3 yards and if you multiply that by 4 you get 40/3. Simplify the fraction and you get 13 1/3
135 think of if you had 90 dollars and you increased it by 50% you would then have $135
Step-by-step answer:
Given:
mean, mu = 200 m
standard deviation, sigma = 30 m
sample size, N = 5
Maximum deviation for no damage, D = 100 m
Solution:
Z-score for maximum deviation
= (D-mu)/sigma
= (100-200)/30
= -10/3
From normal distribution tables, the probability of right tail with
Z= - 10/3
is 0.9995709, which represents the probability that the parachute will open at 100m or more.
Thus, by the multiplication rule, the probability that all five parachutes will ALL open at 100m or more is the product of the individual probabilities, i.e.
P(all five safe) = 0.9995709^5 = 0.9978565
So there is an approximately 1-0.9978565 = 0.214% probability that at least one of the five parachutes will open below 100m
