If you are looking to find the probability of choosing a blue or red marble, the answer is 9/10 or 90%.
Answer:
Step-by-step explanation:
f(x) = 1/2(4)^x
Plug in 3 for x
f(3) = 1/2(4)³
Cube 4.
4³ = 4 x 4 x 4 = 64
f(3) = 1/2(64)
Multiply 64 with 1/2 (or divide by 2)
f(3) = 64/2
f(3) = 32
Answer:
Y=21
X=8
Step-by-step explanation:
In the middle there is a right angle
therefore 27 +3y=90
Y will be 21
Then x+27+63+8x+18=180
x=8
Hence 8+27+3(21)+8(8)+18=180
Answer:
z=1
Step-by-step explanation:
8(z+3)=32
Multiply 8 into the parenthesis.
8z+24=32
Subtract 24 both sides.
8z=8
Divide 8 both sides.
z=1
