Mean : m = 2.2
Standard deviation: s = 0.3
m - 1 s = 2.2 - 0.3 = 1.9
m + 1 s = 2.2 + 0.3 = 2.5
For the normal distribution the values less than 1 standard deviation away from the mean account for 68.27 % of the set.
Answer: D ) 68 %
You estimate the product by rounding to the nearest 10:
9 becomes 10 and 54 becomes 50
9 x 50 = 450
You would do 69sq×3.1416. that gives you 14,957.1576 round it to the nearest hundreth, 14,957.16
Steps:
*Find the unit rate*
1) 1,892.5/ 48.5 = 39
*Multiply it by 64*
2) 39 * 64 = 2,496
So, Boyd's car will travel 2,496 miles on 64 gallons of fuel.
