Answer:
D. Obtain a cluster sample by randomly selecting 20 counties and visiting every restaurant within those counties.
Step-by-step explanation:
Since this executive wants to minimize cost and expenses he should use a cluster sample of 20 counties and using the selected counties as a representative of the whole.

Answer:
The solve of that problem is that Hernry invested $18.000 in stocks and $6.000 in bonds.
Step-by-step explanation:
First, to explain you have to do a multiplication about 6 on three. Like three times more than bonds, the result is 18. Then you have to do a subtraction on $24.000 less $18.000, and the result is $6.000, so six is the amount on bonds. And is three times less than stocks, like the questions ask.
Dunno how to do the linear thing
anyway
9+5=14
14 units=all tents
98=all tents
98=14 units
divide by 14 both sides
7=1 unit
food=9 unit
1 unit=7
times 9
9 unit=63
retail=5 unit
1unit=7
times 5
5 unit=35
a. f+r=98
f/r=9/5 could be the system
b. 63 food tents
c. 35 retail tents
