Answer:
m ≤ 4250
Step-by-step explanation:
What we know:
Mr. Loureiro has to pay $25 plus 10 cents every mile.
The equation becomes 25 + 0.1x = 450
25 + 0.1x = 450
0.1x = 450 - 25
0.1x = 425
x = 4250
So, Mr. Loureiro can travel no more than 4250 mi. (m ≤ 4250)
The answer is 63:)))) promise this is correct 10000%
Answer:
Step-by-step explanation:
Given that confidence level is 95% and sample mean is within 10 minutes of the population mean. i.e. margin of error = 10
Std deviation of population= 211 minutes
Margin of error = Z critical * std error
Std error = sigma/sq rt n = 
Hence we have
\frac{211}{\sqrt{n} }
The minimum sample size is 1710
a) There may not be 1,809 computer users to survey
Answer:
143 oil changes
Step-by-step explanation:
We first find the unit rate.
(91 oil changes)/(7 days) = 13 oil changes/day
Since we want to know the number of oil changes in 11 days, we multiply the unit rate by 11 days.
13 oil changes/day * 11 days = 143 oil changes
Similar to the last problem
y = x + 2
y + 3 = 2x
so we need to find which values fit
