if p(a) = 0.38, p(b) = 0.83, and p(a ∩ b) = 0.57; then p(a ∪ b) =
The value of the union of sets A and B is, P(A ∪ B) is 0.64.
The union of two sets means the total elements in both the sets combined.
Given: sets P(A) = 0.38, P(B) = 0.83, and intersection P(A ∩ B) = 0.57
We need to find the union of P(A ∪ B).
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
Let us substitute the given values in the formula.
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
=0.38+0.83-0.57
=1.21-0.57
=0.64
Therefore, the value of union of sets P(A ∪ B) is 0.64.

(40 POINTS) TRUE OR FALSE? The transformation of the function f(x) = (1/2)^x when it becomes f(x) = (1/2)^x+3 is a horizontal shift of 3 units to the right?
Answer:
False.
Step-by-step explanation:
You can put x=0 into both of the equations to justify. At the first equation, when x=0, f(x)=0. In the second equation, when x=0, f(x)=3. F(x) is the value of y. So, the function has moved 3 units up, not 3 units to the right.

what is the probability a household does not donate to the public television station if the household donates to the public radio station?
We can say that the probability of a household donating to both stations is likely lower than the probability of a household donating only to the public radio station, as donating to both stations would require a higher level of financial commitment.
To determine the probability of a household not donating to the public television station given that it donates to the public radio station, we would need to have data on the number of households that donate to both stations as well as the number of households that only donate to the public radio station. Without this information, it is not possible to calculate the probability.
However, we can say that the probability of a household donating to both stations is likely lower than the probability of a household donating only to the public radio station, as donating to both stations would require a higher level of financial commitment. To answer your question about the probability a household does not donate to the public television station given that they donate to the public radio station, we would need more information. Specifically, we would need the joint probability of donating to both stations and the probability of donating to the public radio station.

The starting price of the toys was $7.50.
What is addition?
Addition is a basic arithmetic operation that combines two or more numbers to get a sum or a total. It is represented by the "+" symbol. When we add numbers, we are finding the total amount when we combine them.
Let's assume the starting price of the toys as "x".
After the first hour, the price of the toys will be "x - 0.25".
After the second hour, the price of the toys will be "x - 0.25 - 0.25 = x - 0.5".
Similarly, after the third hour, the price of the toys will be "x - 0.75".
We can see that the price of the toys decreases by $0.25 every hour. So, after the 8th hour, the price of the toys will be:
x - (0.25 + 0.25 + 0.25 + 0.25 + 0.25 + 0.25 + 0.25 + 0.25)
= x - (8 x 0.25)
= x - 2
We know that after the 8th hour, the price of the toys is $5.50. So we can write:
x - 2 = 5.50
Adding 2 to both sides:
x = 7.50
Therefore, the starting price of the toys was $7.50.

To determine the assignment of employees to jobs that minimizes the total time required to perform the four jobs, we need to consider the time taken by each person to complete each job. Using the given Table 50, we can analyze the data and identify the optimal assignment.
By examining Table 50, we can identify the minimum time taken by each person for each job. Starting with Job 1, we see that Person 4 takes the least time of 16 hours. Moving to Job 2, Person 2 takes the least time of 18 hours. For Job 3, Person 1 takes the least time of 25 hours. Lastly, for Job 4, Person 4 takes the least time of 14 hours.
Therefore, the optimal assignment would be:
- Person 4 for Job 1 (16 hours)
- Person 2 for Job 2 (18 hours)
- Person 1 for Job 3 (25 hours)
- Person 4 for Job 4 (14 hours)
This assignment ensures that the minimum total time is required to perform the four jobs, resulting in a total time of 16 + 18 + 25 + 14 = 73 hours.

How many integers must you pick in order to be sure that at least two of them have the same remainder when divided by 15?
Because of this, we need to choose 16 integers in such a way that we can ensure that when they are divided by 15, at least two of them will provide the same residual.
This is further explained below.
How many integers must you pick in order to be sure that at least two of them have the same remainder when divided by 15?Generally, If you divide a number by 15, the result is a fraction. There are 15 remainders that might occur, and they are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14.
That is to say, if we choose one number and divide it by 15, there is a chance that the remainder may be any of the 15 (0 reminders 14). Therefore, if we choose 15 numbers, we will have the opportunity to pick 15 unique reminders, ranging from 0 to 14.
In conclusion, if we select one more integer, that is we pick 16 integers, then at least two of them would have the same reminder since there are only 15 reminders and 16>15, and by the pigeonhole principle.
Because of this, we need to choose 16 numbers such that we can guarantee that at least two of them will provide the same remainder when they are divided by 15.

How can u find the radius wit the height nd volume
Answer:

Step-by-step explanation:
hope this helps.
A cone with a fixed height of 18 cm is shown on a computer screen. An animator increases the radius r at a rate of 2 cm per minute. Write the function that gives the volume v(r) of the cone as a function of time f(t). Assume the radius is 2 cm at t=1.
Answer:
18.2=36
2.18+38=98
Step-by-step explanation:
The function that gives the volume v(r) of the cone when the height of 18 cm as a function of time is \(24 \pi + 48\pi t + 24\pi t^2\).
Given that:
The height of the cone = 18 cm
The radius of the cone's base at a rate of = 2 cm.
The radius r increases at a rate of 2 cm per minute,
At t = 1,
The radius will be r = 2+ 2t
The volume of the cone is given by \(\dfrac{1}{3} \pi r^3\).
V = \(\dfrac{1}{3} \pi r^3 h\)
= \(\dfrac{1}{3} \pi (2+ 2t)^2(18)\)
= 6\pi (4+ 8t+4t^2)
= \(24 \pi + 48\pi t + 24\pi t^2\)

The point P(2, 9) lies on the curve y = x^2 + x + 3. If Q is the point (x, x^2 + x + 3), find the slope of the secant line PQ for the following values of x.
To find the slope of the secant line PQ, we need to calculate the change in y divided by the change in x between the two points P and Q. The formula for slope is (y2 - y1) / (x2 - x1).
Let's substitute the coordinates of P and Q into the formula:
For x = 3:
P(2, 9), Q(3, 15)
Slope = (15 - 9) / (3 - 2) = 6 / 1 = 6
For x = 4:
P(2, 9), Q(4, 21)
Slope = (21 - 9) / (4 - 2) = 12 / 2 = 6
For x = -1:
P(2, 9), Q(-1, 1)
Slope = (1 - 9) / (-1 - 2) = -8 / -3 = 8/3 or approximately 2.67
