Answer:
the number of families needed for the survey is 2,157
Step-by-step explanation:
The computation of the number of families needed for the survey is shown below:
Given that
The Standard deviation is $900
Service level = 99%
z value at 99% = 2.58
Expenditures = $50
Based on the above information
The number of families needed for the survey is

= 2,157
Hence, the number of families needed for the survey is 2,157
Exact interest rate means there are 365 days in a year
The formula is
A=p (1+rt)
A=3,250×(1+0.1175×(31÷365))
A=3,282.43

We have the following given
mileage = 70 miles per gallon
distance = 60 km
Required: amount of fuel in gallons
First, we must convert the distance to miles, so
60 km (1 mi/1.6 km) = 37.5 mi
So, the amount of fuel is
37.5 mi / (70 mi/gal) = 0.54 gallons
Answer:
$79.7
Step-by-step explanation:
Total income is $(234.8 + 64 + 20) = $318.8
Now, One-fourth of her income is budgeted for car insurance i.e.
dollars.
And, 1/10 of her income is budgeted for gasoline i.e.
dollars.
Finally, 2/5 of her income is budgeted for savings i.e.
dollars.
Therefore, the remaining amount of her income = $(318.8 - 79.7 - 31.88 - 127.52) = $79.7 is left for her spending. (Answer)
