Answer:

Step-by-step explanation:

He's reading at a rate of 1/3 chapter per night and if there 2 1/3 chapters left to read we can divide the chapters left by his reading rate (2 1/3 ÷ 1/3 = 7 nights).

Another way to solve this problem is to make an equation to show the situation with x being the number of nights reading.

1/3x=2 1/3

<em>Solve for x by dividng 1/3 from each side of the equation.</em>

x=7

So he must read for 7 nights to finish the chapters that are left.

Voting age

Levart [38]

Answer:

$\frac{17}{64}\approx 0.27$

Step-by-step explanation:

We have been given a table to voters and their ages. We are asked to find the probability that a voter is younger than 45.

Voting age Voters

17-29 9

30-44 8

45-64 32

65+ 15

We can see from our given table that age of 17 (9+8) voters is between 17 to 44 years.

To find the probability that a voter is younger than 45, we will divide 17 by total number of voters.

$\text{Total voters}=9+8+32+15=64$

$\text{Probability that a voter is younger than 45}=\frac{17}{64}$

$\text{Probability that a voter is younger than 45}=0.265625$

$\text{Probability that a voter is younger than 45}\approx 0.27$

Therefore, the probability that a voter is younger than 45 is 0.27.
