Answer:
OptionB
Step-by-step explanation:
Adding up all 6 probabilities gives a total of 1, which means that this is a valid distribution function. Observing that P(0) = P(5), P(1) = P(4), and P(2) = P(3), this is a symmetric distribution.
Its mean will be in the middle, which is at x = 2.5.
The standard deviation is calculated by multiplying each P(x) by the square of deviation (x - average)^2: (0.032)(0 - 2.5)^2 + (0.152)(1 - 2.5)^2 + (0.316)(2 - 2.5)^2 + (0.316)(3 - 2.5)^2 + (0.152)(4 - 2.5)^2 + (0.032)(5 - 2.5)^2 = 1.242, then taking the square root: sqrt(1.242) = 1.1145.
Answer:
61 years old
Explanation:
You can solve this using an equation. The equation I’m going to use is:
500 - 4x = 256
x will represent the age we are trying to find, so now we will solve to x.
500 - 4x = 256
(- 500 from both sides of the equation)
-4x = -244
(➗-4 on both sides)
x = 61
