Question 2 of 10: you have a budget of $3,000 to spend on a survey. if the base cost of the survey is $850 plus $4.50 per person surveyed,
what is the sample size you can afford?
a) 477
b) 500

A)477

Step-by-step explanation:

Subtract 850 from 3,000

2150

Divide 2150 by 4.50 to find out how many people can be surveyed.

Option A.

Step-by-step explanation:

Base cost of the survey is defined by the expression

Base cost C = 850 + 4.5x

where x = number of persons surveyed

If the budget to spend on a survey is = $3000

Then Number of person we can survey can be determined by

3000 = 850 + 4.5x

4.5x = 3000 - 850

4.5x = 2150

x =

x = 477.78

But the number of persons surveyed can not be in fraction.

Therefore, sample size we can afford is 477.

Option A. is the answer.

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
