Answer:
1.4%
Step-by-step explanation:
Avery's error was ...
measured - actual = 14.7 in - 14.5 in = 0.2 in
As a fraction of the actual length, that is ...
(0.2 in)/(14.5 in) × 100% ≈ 1.4%
The measurement error was about 1.4%.
Maurine owns three bagel shops. Each shop sells 500 bagels per day. Maureen asks her store managers to use a random sample to see how many whole wheat bagels are sold at each store each day. Shop A has total of 50 bagels in sample and 10 are whole wheat bagels. Store B has a total of 100 bagels in sample and 23 are whole wheat bagels. Shop C has 25 total bagels in sample and 7 are whole wheat bagels.
We find fraction of whole wheat bagels to the sample for each shop using given information
Shop A = 
Shop B = 
Shop C = 
The number of whole wheat bagels for each shop that sells 500 bagels per day
Shop A = 
Shop B = 
Shop C = 
Okay it might not be right but I say B
x + 15 = 24
subtract 15 from both sides
x = 24 - 15 = 9
Use the distributive property.
3(6 + x) = 24
18 + 3x = 24
3x = 6
x = 2
