You can make an array like eight rows of four
Answer:
![Probability = \frac{11}{40}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B11%7D%7B40%7D)
Step-by-step explanation:
Given
See attachment
Required
The probability that a 7th grader selected will play guitar.
From the attachment, we have:
![7th\ graders =11+8+8+13](https://tex.z-dn.net/?f=7th%5C%20graders%20%3D11%2B8%2B8%2B13)
![7th\ graders =40](https://tex.z-dn.net/?f=7th%5C%20graders%20%3D40)
7th graders that can play guitars are:
![Guitars = 11](https://tex.z-dn.net/?f=Guitars%20%3D%2011)
So, the probability is:
![Probability = \frac{Guitars}{7th\ graders}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7BGuitars%7D%7B7th%5C%20graders%7D)
![Probability = \frac{11}{40}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B11%7D%7B40%7D)
Answer:
36V²+84V+49
Step-by-step explanation:
since it is (7+6V) in two places,therefore
7(7+6v)+6v(7+6v)
49+42v+42v+36v²
36v²+84v+49
Answer:
x = 25
Step-by-step explanation:
Multiplying both sides by 5 (to get rid of the denominator) gives us:
x / 5 * 5 = 5 * 5
x = 25
