Answer:
C.Infinitely many solutions
I solved by substitution
Infinitely many solutions
Answer:
(D) I think
Step-by-step explanation:
Lets look at our answer choices; A.
The intervals are not comparable. The shorter bar spans more than 10 years. When it comes to a horizontal axis it doesn't matter how far it expands,just if it's expanded correctly.
B.The intervals are appropriately labeled. There not it goes from 25 to 50 in just in instant few climbs up.
C.The intervals are not comparable, but the data on the graph is not misleading. It is misleading the graphs are incorrectly labeled.
Which brings us to our answer D.The vertical axis does not have an appropriate scale. it goes from 0-25 25-50 and 50-75 then 75-100. that's a short distance for such numbers that are pretty far apart.
I hope I'm right and I hope this helps:)!
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
Michael's present age is 53
Step-by-step
17-4=13
John is 13
than when John will be 49
u add 4 to 49
4+49=53
so Michael is 53 because he is 4 years older :)
