Answer:
well you would need to look at how much he gets a weekend, and then worry anout the tips.
Step-by-step explanation:
He gets paid $80 each weekend, and a 15% with tips.
you would need to figure out the tips, by taking the $725 and timesing it by .15 for the percent.
which would be 108.75
you would now take 108.75 and add 80 to get what he made that weekend.
108.75+80 = 188.75 dollars
Answer:
the second i think i dont know for sure
x = 2
Step-by-step explanation:
Since sides have the same base (7), then we can simply write
![{x}^{2} + 11 = 15](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%2011%20%3D%2015)
![{x}^{2} = 4](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%3D%204)
or
![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)

Answer:
The expected value of:
X = 3 green marbles
Step-by-step explanation:
Number of marbles in a bag = 11
Make-up of the bag = 6 red and 5 green marbles
Sussan selects 7 marbles from the bag
The probability of collecting from 5 of the green marbles = 0.45
The probability of collecting from 6 of the red marbles = 0.55
The expected value of X = the probability of selecting a green marble multiplied by the number of marbles selected
= 0.45 x 7
= 3 green marbles
