The table below shows the sample space for spinning a 4-part spinner (labeled A, B, C, D) and then a 5-part spinner (labeled V,
W, X, Y, Z). What is the probability of spinning AZ? A B C D V AV BV CV DV W AW BW CW DW X AX BX CX DX Y AY BY CY DY Z AZ BZ CZ DZ 25% 20% 10% 5%
1 answer:
The probability of spinning an A on the first spinner is 1/4 = 0.25
Since there is 1 outcome we want (landing on A) out of 4 total outcomes (A,B,C,D)
Similarly, the probability of landing on Z is 1/5 = 0.20
There is 1 outcome we want (Z) out of five total (V,W,X,Y,Z)
Multiply the two probability values. This multiplication is only possible because the two events are independent. This is an important condition.
So multiplying the values gets us 0.25*0.20 = 0.05 = 5%
Answer: 5%
Side Note: 1/20 = 0.05 = 5%

Sin < O = 10/15 = 2/3
so m < O = 41.8 degrees
m < Y = 90 - 41.8 = 48.2 degrees
Answer:
15
Step-by-step explanation
We divide the amount he's selling them for, by the amount of money he needs to make.
75 divided by 5 equals 15.
He needs to sell 15 sports drinks to make $75.
Answer:
a) next one is previous one -3
b) next one is 3 times previous one
Km pretty sure it’s C (the third one )
So if x people were surveyed,
people owned a bike and
did not.
The difference between them is 72:
x-\frac{1}{8} [/tex] =72
so this means that
x=72
let's simplify:
x=72
and divide by 3:
x=24
and mupliply by 4:
x=96
so 96 people were surveyed
