Answer:

f(x) = 7(1.06)^8

Step-by-step explanation:

Given : An initial population of 7 chipmunks increases by 6% each year.

To Find: which function could you use to find the population after 8 years?

Solution:

We are given that the function f(x) = ab^x models this situation

Where a is the initial amount.

b = 1+r

r is the rate of change

x is number of years

Since we are given that initial population is 7

So, a = 7

We are also given that chipmunks increases by 6% each year.

So, r = 6%=0.06

So, b = 1+r = 1+0.06 = 1.06

Now we are supposed to find the function which can be used to find the population after 8 years

So, x =8

Substitute the values in the function:

f(x) = 7(1.06)^8

Thus Option B is correct .

Hence the function which represents the population after 8 years is f(x) = 7(1.06)^8

These both go together
Airida [17]

a) We know that the probability Jane will win is 0.2, and draws is 0.3, which leaves the probability of her losing to be 0.5 (1 - 0.2 - 0.3 = 0.5).

I'll begin by filling in for the first game:

win = 0.2, draw = 0.3, lose = 0.5

Next, we'll fill in for if she wins, draws, or loses the second game. The probabilities would be the same as the first game for the second game.

Win (0.2): win = 0.2, draw = 0.3, lose = 0.5

Draw (0.3): win = 0.2, draw = 0.3, lose = 0.5

Lose (0.5): win = 0.2, draw = 0.3, lose = 0.5

b) To find the probability that Jane will win both games, we need to multiply the probability of Jane winning the first game by the probability of her winning the second game.

0.2 x 0.2 = 0.04

Hope this helps! :)

Hey You! Here's How To Solve This Question:


STEP 1:

60 × 2.5 = 150


STEP 2:

54 × 2.5 = 135


STEP 3:

150 - 135 = 15


So, Darnell read 15 more pages than Fran.
