Answer:

7/15

Step-by-step explanation:

To find the probability the student is a senior

P( senior) = number of seniors / total students

= 14 / ( 14+7+4+5)

= 14/30

= 7/15

Answer:

14/30 or 7/15

Step-by-step explanation:

probability = no. of senior students / total no. of students

probability = 14 / (14+7+4+5)

probability = 14/30

This can be simplified to 7/15.

Hope this helps!

Simplify 2p-24/4p-48. Show your work.<br> The answer is 1/2, exclued 12

Molodets [167]

For this case we have the following expression:
$\frac{2p-24}{4p-48} 

$
Factoring the expression we have:
$\frac{2(p-12)}{4(p-12)}$
We now cancel similar terms:
$\frac{2}{4}$
Finally, simplifying the expression we have:
$\frac{1}{2}$
Answer:
$\frac{1}{2}$

How would I solve this and what’s the answer ?

natali 33 [55]

To solve this you just move the letters and numbers around until you get a different equation that is the same as the original equation.

You can also rule out the last two answers because they don’t have all the values.

P = pie

s=2prh can be written as s/2ph=r if we divide s by 2ph because we need to isolate r because all the answers have r isolated.

So the answer would be b s/2ph=r

Sorry that’s really badly worded and confusing, but I hope it helps.
