A golfer's bag contains 24 golf balls, 18 of which are ProFlight brand and the other 6 are DistMax brand. Find the probability t

eduard

Answer:

1. Assuming with replacement, the probability is 7.91%; or

2. Assuming without replacement, the probability is 8.64%

Step-by-step explanation:

Total number of golf balls = 24

Let Pr denotes probability, P denotes ProFlights, D denotes DistMax.

The probability of selecting 5 balls can be with or without replacement. Since the question is silent on this, the answers to the methods are provided as follows:

1. Assuming with replacement

Pr(4 P and 1 D) = (18/24) × (18/24) × (18/24) × (18/24) × (6/24)

= 0.75 × 0.75 × 0.75 × 0.75 × 0.25

= 0.0791 = 7.91%

2. Assuming without replacement

Here, we assume that 4 ProFlights are selected first before 1 DistMax is selected, and the probability is as follows:

Pr(4 P and 1 D) = (18/24) × (17/23) × (16/22) × (15/21) × (6/20)

= 0.7500 × 0.7391 × 0.7273 × 0.7143 × 0.3000

= 0.0864 = 8.64%

Therefore, the probability that he reaches in his bag and randomly selects 5 golf balls and 4 of them are ProFlights and the other 1 is DistMax is 7.91% assuming with replacement or 8.64% assuming without replacement.

Enrollment in a school has grown exponentially since the school opened. A graph depicting this growth is shown. Determine the pe

Yanka [14]

Answer:

4.6%

Step-by-step explanation:

Let the horizontal axis be represented by x and the vertical axis be represented by f(x) or y

The general exponential function is of the form:

$f(x) = a(b)^{x}$

Here,

a = value at the starting of the graph

b = growth factor

In order to find the percentage rate of growth, we need to find the value of b, the growth factor. From the graph we can see two points on the graph: (20, 80) and (25, 100). This means for x = 20, value of f(x) is 80. Using this point in the function equation, we get:

$80 = a(b)^{20}$ Equation 1

Using the second point (25, 100) in the function equation, we get:

$100 = a(b)^{25}$ Equation 2

Dividing Equation 2 by Equation 1, we get:

$\frac{100}{80}=\frac{ab^{25}}{ab^{20}}\\\\ 1.25=b^{5}\\\\ b=1.046$

Using the value of b, the function equation becomes:

$f(x) = a(1.046)^{x}$

This means, after every year, the number of enrollments is 1.046 times the previous year. Or in other words, the number of enrollment is 0.046 times more the previous year. This shows the number of enrollments grow by 0.046 every year which is equal to 4.6%

Thus, the percentage rate of growth is 4.6%
