For this case we have that there are a total of 14 male students and a total of 16 female students. Thus, there is a total of 30 students distributed in the four categories.

On the other hand, we have a total of 8 Junior students.

Then, the probability of selecting a student Junior is \frac {8} {30} * 100 = 26.67

Rounding off we have 27%

Answer:

27%

Answer:

Combine the ones to make 8 ones

Step-by-step explanation:

It seems the most reasonable. (Also, all the other options are wrong-) I just don't see why it's making you go through this process when you can just add 12 + 6 in your head lol.

If the original number is 15 and the new number is 5, what is the percent decrease?
Arlecino [84]
When a quantity grows (gets bigger), then we can compute its PERCENT INCREASE:

[beautiful math coming... please be patient] <span><span>PERCENT INCREASE=<span><span>(new amount−original amount)</span>original amount</span></span><span>PERCENT INCREASE=<span><span>(new amount−original amount)</span>original amount</span></span></span>

Some people write this formula with <span><span>100%</span><span>100%</span></span> at the end,
to emphasize that since it is percent increase, it should be reported as a percent.

So, here's an alternate way to give the formula:

<span><span>PERCENT INCREASE=<span><span>(new amount−original amount)</span>original amount</span>⋅100%</span><span>PERCENT INCREASE=<span><span>(new amount−original amount)</span>original amount</span>⋅100%</span></span>

Recall that <span><span>100%=100⋅<span>1100</span>=1</span><span>100%=100⋅<span>1100</span>=1</span></span> .
So, <span><span>100%</span><span>100%</span></span> is just the number <span>11</span> !
Multiplying by <span>11</span> doesn't change anything except the name of the number!
Hope this helps

Mr. James will solve the equation 150x = 2200 for x in one step. Which proportion is the MOST appropriate step for Mr. James to
scoray [572]

Answer:

14.67

Step-by-step explanation:

Mr. James will solve the equation 150x = 2200 for x in one step. Which proportion is the MOST appropriate step for Mr. James to use?

We have the Equation

150x = 2200

Divide both sides by 150

150x/150 = 2200/150

x = 14.666666667

Approximately x= 14.67
