Subtract x/a from both sides.
y/b=1-x/a
Multiply by b on both sides.
y=b(1-x/a)
If you want, you can leave it like that or you can distribute the b through.
y=b-bx/a

Step-by-step explanation:
Assume the mattress have no width, only length.
By Pythagoras' Theorem, √(72^2 + 80^2) = 107.6 inches.
The <em><u>correct answer</u></em> is:
1.5% of the scores, or 3 people.
Explanation:
A z-score tells the number of standard deviations a data point is from the mean. Since Bob's score is 2.17 standard deviations above the mean, that means his z-score is 2.17.
Using a z-table, we find the probability that a score would be to the left of, or less than, this value. In the table, this is 0.9850. However, we are interested in the number of people that scored <em>higher</em> than Bob. This means we subtract this from 1:
1-0.9850 = 0.015.
This is the percentage of people that scored higher than Bob. To convert to a percent, multiply by 100:
0.015*100 = 1.5.
To find the number of people that scored higher than Bob, take 1.5% of 200:
0.015(200) = 3.
