Answer:
The length is 73 m, and the width is 59 m.
Step-by-step explanation:
perimeter = 2 * length + 2 * width
Let the width = w
length = w + 14
width = w
perimeter = 2 * (w + 14) + 2 * w
perimeter = 2w + 28 + 2w
perimeter = 4w + 28
perimeter = 264
4w + 28 = 264
4w = 236
w = 59
length = w + 14 = 59 + 14 = 73
Answer: The length is 73 m, and the width is 59 m.

Step-by-step explanation:
Answer: A. 0 to 100 per hour
==================================================
Explanation:
The phrasing "Depends on its speed" tells us that the speed is the independent variable, and therefore it's the x variable.
The domain is the set of allowed x values of a function, or allowed inputs. In this case, it appears the car's max speed is 100 mph.
Answer:
H0 : p = 0.75
H1 : p ≠ 0.75
Step-by-step explanation:
The population proportion, P0 = 0.75 ;
Claim is that proportion of customers who use online coupons when making purchases is actually different than P0 = 0.75 (this is the calm) and the difference could be either more or less
Hence, the null hypothesis H0 : says P0 is 0.75 ;
H0 : p = 0.75
The alternative hypothesis, negating the null hypothesis argues that the proportion is not 0.75 (the difference could be either to the right or left).
H1 : p ≠ 0.75
6(4.25) + 3(6.75) = 45.75
She spent $45.75 in total.
