Answer:
15-3
Step-by-step explanation:
15x3=45 or it could be 3-15
Answer:
37
Step-by-step explanation:
Here, we have two different samples, hence, to obtain the confidence interval, we use the relation for the confidence interval for two sample means ;
(x1 - x2) ± Margin of error
Where, (x1 - x2) = point estimate of the sample mean, this is the difference in mean of the two samples.
From the question ;
x1 = 1150 ; x2 = 1113
Hence, the point estimate is : (1150 - 1113) = 37
8x+30/10
Simplify the Problem
<em><u>8x+3</u></em>
74.75 for 5 gallon unit rate
74.75 / 5 = 14/95
Answer: $14.95 per gallon of paint
Therefore, about 15 dollars per gallon of paint since we need to estimate.
If you multiply 1/4 by 2 it would be 2/8 so if you compare 2/8 and 5/8 she bought 3/8 pounds more
