Answer of your question,
3x+46 = 10x-80
7x = 34
x = 4.85
Answer:
0.089
Step-by-step explanation:
Since there are 9 art majors, the probability of the first student being chosen is 9 out of the 29 students total. The second student is being chosen from a sample of 28 students and 8 art majors.
9/29=.31
8/28= .286
.31 x .286=0.089
You'll need to write your question a bit clearer. It's difficult to understand because a lot of it seems jumbled together.
Answer:
B, E
Step-by-step explanation:
It can be helpful to factor the first two terms:
f(x) = x^2(x -7) +36
This can make it easier to evaluate the function for different values of x.
The answer choices suggest you need to know whether f(5) and f(-14) match the values given here.
f(5) = 5^2(5 -7) +36 = -50 +36 = -14 . . . . matches choice B (and E)
f(-14) = (-14)^2(-14-7) +36 = -21(196) +36 . . . . <em>does not match</em> choice A (or D)
__
The one remaining answer choice we need to consider is C. If we look at f(0) for this equation, we find it is (-5)(-10) +14 = 64, which <em>does not match</em> f(0) = 36 for the function given in the problem statement.
The only true answer choices are B and E.
_____
The remainder theorem tells you that f(a) = the remainder from f(x)/(x -a).
