Answer:
x=11
Step-by-step explanation:
You do 38/3x+3 and 19/x+7 and then cross mulitply and get 57x+57=38x+266. Then yoy subtract 57 from 266 and get 57x=38x+209. Now you have to subtract 38 from 57 and then answer will be 19. So now you have 19x=209. Finally you divide 209 by 19 and get x=11. Good luck!
Answer:
470 zombies
Step-by-step explanation:
To find how many they killed, multiply 724 by 0.65
724(0.65)
= 470.6
Round down to 470, since there can only be a whole number for zombies
So, the player killed approximately 470 zombies

<u>Probabilities</u>
One approach to estimating the probability of occurrence of an event is to record the number of times that event happens (e) and compare it with the total number of trials (n).
The probability can be estimated with the formula:
![\displaystyle P=\frac{e}{n}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20P%3D%5Cfrac%7Be%7D%7Bn%7D)
And the probability that the event doesn't occur is
Q = 1 - P
Paulo arrives on time to school e=53 times out of n=79 times. The probability that he arrives on time is:
![\displaystyle P=\frac{53}{79}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20P%3D%5Cfrac%7B53%7D%7B79%7D)
P = 0.67
And the probability he arrives late is:
Q = 1 - 0.67 = 0.33
