At a local University, it is reported that 81% of students own a wireless device. If 5 students are selected at random, what is

Sphinxa [80]

Answer:

34.87% probability that all 5 have a wireless device

Step-by-step explanation:

For each student, there are only two possible outcomes. Either they own a wireless device, or they do not. The probability of a student owning a wireless device is independent from other students. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

81% of students own a wireless device.

This means that $p = 0.81$

If 5 students are selected at random, what is the probability that all 5 have a wireless device?

This is P(X = 5) when n = 5. So

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 5) = C_{5,5}.(0.81)^{5}.(0.19)^{0} = 0.3487$

34.87% probability that all 5 have a wireless device

The path of a baseball after it has been hit is modeled by the function h = – 0.0032d2 + d + 3, where h is the height in feet of

aleksandr82 [10.1K]

Answer:

the maximum height of the ball is 81.125 feet above the ground. when the ball is at its peak, the ball is 156.25 feet away from home plate.

Step-by-step explanation:

x = d

y = h

to find the x coordinate of the vertex of a parabola, use the equation

x = -b/2a

y = ax^2 + bx+ c

y = – 0.0032x^2 + x + 3

x = -1 / 2 • - 0.0032

x = 156.25

plug x into original equation to find the the y coordinate of the vertex

y = – 0.0032 • (156.25)^2 + (156.25) + 3

y = – 0.0032 • 24414.0625 + 159.25

y = – 78.125 + 159.25

y = 81.125
