U. s census bureau data shows that the number of families in the united states (in millions) in year x is given by h(x)= 51.42 + 15.473 + log x, where x=0 is 1980. how many families were there in 2002? a. 90 million b. 48 million c. 72 million d. 21 million

C. 72 million

Step-by-step explanation:

Put the appropriate value of x into the correct formula and do the arithmetic.

... For the year 2002, x = 2002 -1980 = 22.

Then the population estimate is ...

... h(22) = 51.42 +15.473·log(22)

... = 51.42 +15.473·1.3424

... = 51.42 +20.77

... = 72.19 ≈ 72 . . . . million . . . . . matches choice C.

b). 4320 have a nice day

the answer is 5/14.

hope this .
