Answer: 15. A. Proportional 16. B. 50 mph
Step-by-step explanation: The price and the number of apples are proportional based on the info you have given us. And B. 50 is correct because 100 miles in 2 hours is 100/2 which equals 50/1 so the unit rate would be B. 50 mph.
Answer:
50
Step-by-step explanation:
all your doing is dividing 100 by 20 and u get 50
Answer: 0.1 or
=
m ≥ 3
m is greather or equal to 3
m + 4 ≥ 7
m ≥ 7 - 4
x is the cherries eaten
0.078
Margin of error = z√(p(1-p)/n)
Given
p-hat = 0.43
n = 270
z at 99% confidence interval = 2.576
Substitute
MOE = 2.576√0.43(1-0.43)/270
MOE = 2.576√0.43*0.57/270
MOE = 2.576√0.2451/270
MOE = 2.576*0.030129
MOE = 0.078
Hence the margin og error is 0.078
Lets see,
.
Hope this helps.
