Answer:
A
Step-by-step explanation:
First you subtract the total budget by what she has already spent:
4994-2105=2889
She has $2,889 left to spend in her budget.
You divide this number by how much a meal costs for one guest.
2889/27=107
This means she can have a max of 107 guests at her wedding, which means your answer would be A
Answer:
Step-by-step explanation:
f(x)= 3x+1 and g(x)= x^2 - 6
we need to find (f*g)(x)
(f*g)(x)= f(x) * g(x)
Plug in the given f(x) and g(x)
Apply FOIL method to multiply it
A) (-8,0)
B) (-2,8)
C) (-2,-6)
Answer:
126
Step-by-step explanation:
To calculate this, we need to assume at least one white marble will be picked... so let's take it out of the bag. Then we need to pick 4 more marbles... it's just then a combination calculation.
How many marbles is there in total? 4 + 3 + 2 + 1 = 10
We do just as if we had removed one white marble from the bag... so that leaves 9 in the bag.
We have to pick 4 out of those 9.... so, it's simple combination calculation:
C(9,4) = 9! / (4! (9--4)!) = 9! / (4! 5!) = 126
Some of those grabs will have 2 white marbles... but we're assured that there are 126 ways to combine the 10 marbles so there's at least one white in the 5 picked (since we forced it in our calculations).
