Answer:
c
Step-by-step explanation:
1/4 + 7/8 =
2/8 + 7/8 Convert the 1/4 to the denominator as 8 so we can add the top number.
9/8 Add the top number.
1 1/8 Simplifly the result.
First thing you have to do is divide up the 3 columns on the right so that all of the squares are the same size. (I did that in black, you can see it on the picture I attached). Then total all of the little squares. I did this in red, and got 50. Now just count up how many of the lighter colored squares you have, I highlighted them in yellow on my picture. I got 14 light squares. So you end up with fourteen light squares out of 50 total squares, which is 14/50. *apologizes for the bad handwriting on the image I did it on phone. If that didn’t help just comment and let me know what’s still unclear.
Cos x = 15÷17
because cos is adjacent side over hypotenuse.
Answer:
Step-by-step explanation:
Given that X, the hip width of men is N(14.2, 0.9)
i.e. we have
is N(0,1)
Seat width an airline uses = 16.7 inches.
a) the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.7 in

b) Here sample size = 126
Each person is independent of the other
the probability that these men have a mean hip breadth greater than 16.7
=
<0.00001
c) part a is important since even a single person not fitting will cause embarassment and leads to customer dissatisfaction.
