6. 150 degrees
7. 70 degrees
8. 100 degrees
and are independent and identically distributed with PMF
If , then has range/support
{-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5}
where we can get
- -5 = 1 - 6 in 1 way, hence with probability 1/36
- -4 = 1 - 5 = 2 - 6 in 2 ways, with probability 2/36 = 1/18
- -3 = 1 - 4 = 2 - 5 = 3 - 6 in 3 ways, with probability 3/36 = 1/12
and so on, so that the PMF of is
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 =84
Step-by-step explanation:
25/100*Y = 21
100/25 * 25y/100 =21 *100/25
y = 2100/25
y = 84
