First convert the 2 1/2 into eighths to be able to subtract the numbers. That becomes 2 4/8. Next set up the subtraction. 11 1/8 - 2 4/8. Note that 4/8 is bigger than 1/8, meaning we have to borrow 8/8 from 11 making our problem 10 9/8 - 2 4/8. Now we subtract as normal: 10 - 2 = 8; 9/8 - 4/8 = 5/8.
Final answer: 8 5/8 inches
Since the average height is 60 inches and its deviation is 2 inches, one deviation to the right (or higher) is 62 inches (60 + 2). Two deviations is 64 inches, three deviations is 66 inches, and four deviations is 68 inches.
Since the average weight is 100 pounds and its deviation is 5 inches, we repeat the process from finding heights to get to 115 pounds. That takes three deviations.
The MORE deviations away, the more unusual it is. So the height (4 deviations) is more unusual than the weight (3 deviations).
Answer
.50
Step-by-step explanation:
by what your looking at 2 x .50 = 1.00
all you do is multiply
Well you use the same process really. Taking the individual numbers, lining them up and adding them. However, it is much more difficult because there is more to remember and you have to carry over more numbers. <span />
