You spin a wheel of fortune that is equally likely to end up pointing to any decimal number between 0 and 1, and you win if it points to a number between 0.50 and 0.55. If you spin this wheel 100 times, the mean and standard deviation of the number of times you win are closest to which of the following? a. 5.0 and 2.18, respectively
b. 10.0 and 3.0, respectively
c. 5.0 and 4.75, respectively
d. You can’t tell because the result of a single spin is not normally distributed

a. 5.0 and 2.18, respectively

Step-by-step explanation:

n = numbers of spins = 100 times

p = 0.55 - 0.50 = 0.05

q = 1 - 0.05 = 0.95

Mean = n x p = 100 x 0.05 = 5

Standard Deviation =

Standard Deviation =

Standard Deviation =

Standard Deviation = 2.1794

Standard Deviation = 2.18

step-by-step explanation:

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
