Consider the normal distribution curve. A graph shows the horizontal axis numbered 50 to 78. There is no vertical axis. Variance

= 7. A line shows an upward trend from below 50 to 64 and a downward trend from 64 to Over 78. The space beyond 78 is labeled x. Which statements are true about the curve? Check all that apply. The standard deviation of the data is 64. The variance of the data is 49. The median is 64. The data point 75 is less than one standard deviation from the mean. The data point 50 is two standard deviations away from the mean.

Calculate the expected value of playing a lottery ticket game where each ticket costs $5, and the chance of having winning ticke
Amanda [17]

Answer:

$4895

Step-by-step explanation:

P(winning) = 1 / 1000000 = 0.000001

P(not winning) = 1 - 1/1000000 = 0.999999

Winning amount = 4,900,000,000 - 5 = 4899999995

Amount lost = - 5

__ X: - 5 _________ 4899999995

P(X) : 0.999999 ___ 0.000001

Expected value E(x) = Σx * p(x)

E(x) = - 5(0.999999) + 4899999995(0.000001)

E(x) = - 4.999995 + 4899.999995

E(x) = 4895

Hence, expected value is 4895

Why can't you have a shoe size of 4.5 and a height of 72 inches?
liq [111]

Answer:

Ok, lemme say something.

4.5 shoes are for 9 inch feet.

Dont think a 6 foot person is gonna fit tbh.

Step-by-step explanation:

A shoe size is for relation to feet size. Your feet grow from your height too, along with weight. If you are 6 feet, your feet are gonna be more than at least 1 foot.

4.5 shoes are for 9 inch feet

1 foot = 12 inches.

12 > 9.

12-9=3.
