Answer:
It would be 60
Step-by-step explanation:
So 3(3*5 + 5) so 3*5 would be 15, 15+5=20, and 20*3=60
This is really simple if you can't figure this out, you might as well go back to 1st grade and below

Answer: 127 cookies
Step-by-step explanation:
1. If you look back to the text you will see that 12 is 1 in 1:3:4 and you multiply that by 2. 12 * 2 = 24.
2. Divide 24 by 3 and that gives you 8 than times it by 5 for it to give you 40
3. Divide 36 by 4 and that equals to 9 than multiply it by 7 which that gives you 63
4. Add 24, 40, and 63 for it to give you 127
Thank you for following these steps if it is correct and this is my first time so if I am incorrect I will look upon my mistake and correct and help many of you people who need help

Step-by-step explanation:
Answer:
12.39
Step-by-step explanation:
18% 10.50 = 1.89
10.50+1.89 = 12.39
Answer:
![Var(X) = E(X^2) -[E(X)]^2 = 4.97 -(1.61)^2 =2.3779](https://tex.z-dn.net/?f=%20Var%28X%29%20%3D%20E%28X%5E2%29%20-%5BE%28X%29%5D%5E2%20%3D%204.97%20-%281.61%29%5E2%20%3D2.3779)
And the deviation would be:
Step-by-step explanation:
For this case we have the following distribution given:
X 0 1 2 3 4 5 6
P(X) 0.3 0.25 0.2 0.12 0.07 0.04 0.02
For this case we need to find first the expected value given by:
And replacing we got:
Now we can find the second moment given by:
And replacing we got:
And the variance would be given by:
And the deviation would be:
