Choosing blue or red: 3 blue + 4 red = 7 marbles
3 blue + 2 green + 4 red + 1 yellow = 10 marbles
Probability blue or red marble: 7/10
Choosing a marble that isn't blue or red: 2 green + 1 yellow = 3 marbles
Total marbles: 3 blue + 2 green + 4 red + 1 yellow = 10 marbles
Probability non-blue or red marble: 3/10
Answer:
WR = 26
Step-by-step explanation:
Givens
UT = 10
VS = 18
WR = ??
Formula
(WR + UT) / 2 = VS
Solution
Substitute
(WR + 10) /2 = 18
Multiply both sides by 2
(WR + 10/2 * 2 = 18 * 2
Do the multiplication
WR + 10 = 36
Subtract 10 from both sides
WR + 10 - 10 = 36 - 10
WR = 26

Answer:
f(g(2)) = -11
Step-by-step explanation:
f(g(2))=
First we need to find g(2)
g(x) = 3x-4
We let x=2
g(2) = 3(2) -4
6-4
=2
Now we stick the value of g(2) in for x in f(x)
f(x) = -2x^2 - 3
f(2) = -2(2)^2 -3
=-2 (4) -3
= -8 -3
=-11
