Question:
The circumference of a clock is 22 inches. What is the radius of the clock?
Answer:
Radius = 3.5 inches
Solution:
Shape of the clock is circle.
Circumference of the circle = 2πr
Circumference of a clock = 22 inches
⇒ r = 3.5 inches
Hence the radius of the clock is 3.5 inches.
Answer:
a). The mean = 1000
The variance = 999,000
The standard deviation = 999.4999
b). 1000 times , loss
Step-by-step explanation:
The mean of geometric distribution is given as ,
And the variance is given by,
Given :
= 0.001
The formulae of mean and variance are :
a). Mean =
=
= 1000
Variance =
=
= 999,000
The standard deviation is determined by the root of the variance.
= = 999.4999
b). We expect to have play lottery 1000 times to win, because the mean in part (a) is 1000.
When we win the profit is 500 - 1 = 499
When we lose, the profit is -1
Expected value of the mean μ is the summation of a product of each of the possibility x with the probability P(x).
= $ 0.50
Since the answer is negative, we are expected to make a loss.
