Answer:
Step-by-step explanation:
Use the formula to find the z-score, then go to the table that will give you the probability that the value is less than this z-score.
![z=\frac{53-50}{3}=1](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B53-50%7D%7B3%7D%3D1)
The probability that the value lies to the left of 1 on a standard bell curve is 84.1345%, or 84%, the third choice down.
Total number of marbles : 12
amount of blue marbles : 4
4/12 = 1/3 or 33%
the probability of choosing a blue marble 1/3 or 33%
For this case we have the following product:
![(x-4) (x + 3) ](https://tex.z-dn.net/?f=%28x-4%29%20%28x%20%2B%203%29%0A)
We must use the distributive property correctly to solve the problem.
We have then:
![x ^ 2 + 3x - 4x - 12 ](https://tex.z-dn.net/?f=x%20%5E%202%20%2B%203x%20-%204x%20-%2012%0A)
Then, we must add similar terms.
We have then:
Answer:
The final product is given by:
option 2
If the question is how much do they make the answer would be they make 35 dollars because 25 + 40 =65 and 100-65=35
