Answer:
yes
Step-by-step explanation:
I think I can bravely ignore the Freudian slip and solve this one.
-- If the mean of 5 tests is 90, then all 5 scores add up to (5 x 90) = 450
-- The sum of her first 4 scores is (95+ 90 + 85 + 95) = 365
-- If she has one more test to average 90, then she needs
to score (450 - 365) = <u>85</u> on it.
That looks like choice 'G '.
So you want to find how many miles are being flown in one hour.
There are 60 minutes in one hour so you want to find how many times 15 goes into 60 so you can then multiply that by 115.
60 / 15 = 4.
Now multiply 115 by 4,
115 x 4 = 460
Therefore the plane is flying at B. 460 mph.
Hope I helped!
