Question

Story problem
"According to the US Bureau of the Census, the world population in the year 1950 was A=2555360972, and in 2000 it was B=6079006982 We'll use A and B so we don't have to keep writing those large and idiosyncratic numbers. We usually use y and x in the equation of a line, but in this and the following problem let's use N and t instead. t stands for time and N for the size of the population.
If N(t)=mt+b
such that N(1950)=A and N(2000)=B, then m=[blank]and b=[blank]
Suppose you want to estimate the population in 1975. To that end you compute N(1975) =[blank]

Answer 1

This is the last online homework question that I'm stuck on...
I have no clue how to do it...also I ran out of characters in the question..at the end, it says:
"(Round your answers to the nearest integer. The process illustrated in this problem is called linear interpolation.)"

Answer 2

I just had that same math problem last week for my class :p...

Answer 3

ahaha

Answer 4

lol that was complicated took me a week to come up with the answer. i had to submit it online too lol.

Answer 5

:( hmm does it let you view the answer or no?

Answer 6

at the time yes. but once the deadline day arrives they take it down. which sucked.

Answer 7

:( could you tell me how to do it or something, the deadline is 10/14

Answer 8

It's the formula y=mx+b, and replace with the numbers. You'll have three different answers.

Answer 9

yeah I know, it is still quite hard and I can't get it :/

Answer 10

yeah. im not sure what the results were b/c my deadline was last week and my teacher removed it. and i'm still puzzled with that one. but i do remember that one will be a negative answer. i'm almost certain.

Answer 11

Step 1: draw a picture
How would you find the slope of that line?
