Answer:
7/504
Step-by-step explanation:
there are 504 possibilities of your mom winning and 7 out of tjose are the odds of her winning.
24x + 7=79
subtract 7 from both sides
24x + 7 - 7= 79 - 7
24x= 72
divide both sides by 24
x= 3
CHECK:
24x + 7= 79
24(3) + 7= 79
72 + 7= 79
79= 79
ANSWER: x= 3
Hope this helps! :)
Answer:
C. cos 20/29
Step-by-step explanation:
Cosine is adjacent over hypotenuse, like SohCahToa. Therefore, 20 is the adjacent side and 29 is the hypotenuse (hypotenuse is always the longest side).
The mean is not the same thing as median
mean=78+81+85+87=331
mean=331/4=82.75
median is the middle number, but you have a par set of numbers, so your median will be the middle numbers 78,81,85,87 , which are 81+85=166, 166/2=83
83 is your median
