Answer: A, C, and E

Step-by-step explanation:

Hi, to answer this question we have to analyze the function given:

C(b) = 2.75b + 10

Where:

  • Independent variable: b (number of books)
  • Input = b
  • Output = C = annual cost

So:

A. The number of books purchased is the independent variable. TRUE  

B. The input is the yearly cost. (FALSE, the input is the number of books )

C. The total yearly cost depends on the number of books purchased. TRUE

D. The number of books purchased is determined by the yearly cost. FALSE , the yearly cost is determined by the number  

of books.

11 mushrooms

mixer [17]

How many of the 3271 subjects used at least one prescription​ medication? Round to the nearest integer as​needed.)

Answer:

2902

Step-by-step explanation:

Let the total number of adults within the mentioned age bracket be n=3271

The proportion of adults who used at least one prescription medication be p=88.7%=0.887

The point estimate of population is given by

p=\frac {x}{n} where x is number of individuals in the sample with the specified characteristics and n is the sample size.

Let x be the adults who used at least one prescription medication

0.887=\frac {x}{3271}

x=3271*0.887=2901.377\approx 2902

Carson needs 3 quarts of water to make fruit punch, but has only a l-cup measuring cup.
olga_2 [115]

Answer:

Cups of water she needs to make the punch is 12.

Step-by-step explanation:

Amount of water Carson need to make fruit punch = 3 quarts

2 cups is 1 pint

2  pints is 1 quart

1 pint = 1/2 quarts

2 cups is 1 pint which is 1/2 quarts

So, 1 cup:

1 cup is 1/2 times 2 quarts

1 quart is 1 times 2 times 2 cups equals 4 cups

So, 3 quarts equals 3 times 4 cups which equals 12 cups.

So it is 12 cups.
