sweet-ann [11.9K]

Answer:

62.29%

Step-by-step explanation:

The probability of Aya being offered a coupon on at least one of the six days she visits the website is 100% minus the probability that she is not offered a coupon on any of the six days, which is described by a binomial probability with zero successes in six trials with a probability of succes p = 0.15.

P = 1 - (\frac{6!}{(6-0)!0!}* p^0*(1-p)^{6-0})\\P = 1 - (1* 1*(1-0.15)^{6})\\P=0.6229=62.29\%

The probability that Aya will be offered a coupon on at least one of the days she visits the website is 62.29%.

Please help!!
iragen [17]

Answer:

Option (C)

Step-by-step explanation:

Cost of ordering the number of shirts is represented by the function,

f(x) = 12.75x + 3.5

where x = number of players in the bowling team

Since number of players a bowling team can have,

6 ≤ x ≤ 10

Therefore, domain of the function: 6 ≤ x ≤ 10

For x = 6,

f(6) = 12.75(6) + 3.5

     = 80

For x = 7,

f(7) = 12.75(7) + 3.5

     = 92.75

For x = 8,

f(8) = 12.75(8) + 3.5

     = 105.5

For x = 9,

f(9) = 12.75(9) + 3.5

     = 118.25

For x = 10,

f(10) = 12.75(10) + 3.5

      = 127.5 + 3.5

      = 131

Therefore, for the given domain range of the function will be,

Range : {80, 92.75, 105.5, 118.25, 131}

Option (C) will be the answer.

The headlights of an automobile are set such that the beam drops 3 in for each 32 ft in front of the car. What is the angle (giv
Anastaziya [24]

Answer:

0.4476 degrees.

Step-by-step explanation:

Let θ be the angle between the beam and the road. The given values form a right triangle with the distance that the beam drops ( h=3 in) being the side opposite to θ and the distance in front of the car (x=32 ft or x=384 in) being the side adjacent to θ.

Therefore, θ is given by:

tan^{-1}(\theta) = \frac{h}{x}\\tan^{-1}(\theta) = \frac{3}{384}\\ tan^{-1}(\theta) = \frac{1}{128}\\\theta=0.4476^o

The angle between the beam and the road is 0.4476 degrees.
