Answer:
if $0.25 for each mile, then $1.00 =1 mile.
so the first day would be = $1=1mile
$n=11 miles
= 1n= 11×1=$ 11
Step-by-step explanation:
and the 2nd day is = 14×1= $14.
So the answer is 14+11=$25.00
Answer: Yes
Step-by-step explanation:
2:3 is the same as (2/3) and 4:6 is the same as (4/6). (4/6) can be reduced by dividing both sides by 1/22: (4/6)*(1/2)/(1/2) = 2/3, They are the same.
Answer:
1509
Step-by-step explanation:
We know that, formula for number of samples is,

When nothing is given, we take
and we know that
.
SE = 0.03 (the true proportion should remain withing 3%)
Putting the values we get,


Therefore, the sample required to estimate the true proportion to within 3 percentage points is 1509.
10% is 90 1% is 9 90x4 is 360 add 9 is 369 nearest hundred is 400 i guess but the answer is deffinately 369
