Answer:

24 : 84 = 2 : 7

Step-by-step explanation:

We can simplify the ratio 24 : 84 by dividing both terms by the greatest common factor (GCF).

The GCF of 24 and 84 is 12.

Divide both terms by 12.

24 ÷ 12 = 2

84 ÷ 12 = 7

Therefore:

24 : 84 = 2 : 7

Many U.S employees received a 3% raise in 2012. Suppose an employee made $47,000 in 2011 and received a 3% raise. What did she m
Hoochie [10]
First lets get 3% into decimal form. 

3% is 3/100  = 0.03

Now multiply 0.03 by 47000 to get how much extra money she was going to get. 

47000 * 0.03 = 1410

Now we just add
47000 + 1410 = 48410 is what she was going to make in 2012

Another way to do this is 

(47000)(1+0.03) = 48410

you would use (1+0.03) which tells you she increased in pay.

20 POINTS WILL MARK BRAINLIEST
Alika [10]

Answer:

Step-by-step explanation:

A.  It says he will get to sit in the front if the number is even

There are 6 sides, three of which are even numbers (2,4,6). So the probability of rolling an even number is 3/6 = 1/2.

Let's make p = 1/2

Jack will get his way half of the time, so we expect him to get the front seat half of the time

If we're talking about 20 days, then n = 20 and

n*p = 20*(1/2) = 20/2 = 10

meaning that Jack would, on average, get the front seat 10 times out of the 20 total.

B. Similar to A

n=100

The probability is still the same because rolling an odd number (1,3,5) is still going to happen 3/6 = 1/2 of the time.

so: n*p means 100 days*1/2 which is 100/2=50 days

Jill get to sit in the front 50 out of the 100 days.

C. For better accuracy, we can at least increase the number of trials so we have more data in able for better accuracy.

As Jill did 100 hundred, we think that she will get closer to the actual frequency. As larger the number of trials, the closer we'll get to the expected probability.
