irina1246 [14]

Answer:

<em>The relative change from Bloomington to Kokomo is  -12.449...%</em>

Step-by-step explanation:

<em>Formula for percentage of relative change = (Amount of relative change/ Initial amount)× 100%</em>

So, the percentage will be:  \frac{-93}{747}\times 100\% =-12.449.... \%

What is the prime factorization of 24?<br>1. 2x2x2x3<br>2. 2x2x3<br>3. 8x3<br>4. 6x4​
nika2105 [10]

Answer:

1. 2x2x2x3

Step-by-step explanation:

Let's do process of elimination.

2. 2x2x3

2x2=4   4x3=12

2 is false.

3. 8x3

8x3=24

3 is true, but 8 is not a prime number.

4. 6x4​

6x4=24

4 is true, but 6 is not a prime number.

This leaves 1. 2x2x2x3.

1. 2x2x2x3

2x2=4    2x3=6     6x4=24

1 is true, and 2 and 3 are prime numbers. So, the answer is 1.

There are 420 students. 63 students were out sick. What percent of the student population is ill?
emmainna [20.7K]
To find the percentage,here's what we can do:
\frac{student \: out \: sick}{original \: population} \times 100\%

The percentage would then be:
=63/420×100%
=3/20×100%
=0.15×100%
=15%

Therefore the answer is 15%.

Hope it helps!
