Voting in Seaside's annual school board elections has been going down by 10% from one election to the next. If 990 parents voted this year, how many will vote 4 years from now?
If necessary, round your answer to the nearest whole number.
Answers
Answer:
FV= 676
Step-by-step explanation:
Giving the following formula:
Present value (PV)= 990 parents
Decrease rate (d)= 10% = 0.1 per year
Number of periods (n)= 4
To calculate the future value of votes, we need to use the following formula:
FV= PV / (1 + d)^n
FV= 990 / (1.1^4)
FV= 676
M is the midpoint of AB. If the coordinates of A are (-1,5), and the coordinates of M are (3,3), what are the coordinates of B?
I need the answer asap!
Answers
Answer:
B = (5, 1).
Step-by-step explanation:
From the formula for the midpoint of a line :-
(-1 + x)/2 , (5 + y)/2 = (6/2, 6/2) where x and y are the coordinates of B.
so (-1 + x)/2 = 6/2
-1 + x = 6
x = 5.
and (5 + y)/2 = 6/2
5 + y = 6
y = 1.

a bank has set a standard that mortgage applications be processed within a certain number of days of filing. if, out of a sample of 1000 applications, 75 fail to meet this requirement, what is the epmo metric?
Answers
The Epmo metric is 0.075.
Given in the Question:
We have given there are a sample of 1000 applicants
So, total number of applicants = 1000
In which 75 fail to meet the requirement
So the number of applicants who fail to meet the requirement = 75
Now, we will find the epmo metric.
We will use the formula of epmo metric:
epmo metric = number of applicant to fail to meet the requirements/
total number of applicants
epmo metric = 75/1000
= 0.075
Hence, the epmo metric is 0.075.

You are given 100 cups of water, each labeled from 1 to 100. Unfortunately, one of those cups is actually really salty water! You will be given cups to drink in the order they are labeled. Afterwards, the cup is discarded and the process repeats. Once you drink the really salty water, this "game" stops. i. What is the probability that the įth cup you are given has really salty water?
Answers
The probability that the įth cup you are given has really salty water can be determined by considering the total number of cups and the number of cups that are really salty.
Given that there are 100 cups labeled from 1 to 100, there is only one cup that is really salty. Therefore, the number of cups that are really salty is 1. The total number of cups is 100. Since you drink the cups in order, starting from cup 1 and proceeding to cup 2, cup 3, and so on, the probability of encountering the really salty cup on the įth cup depends on the position of the really salty cup in the order.
If the really salty cup is labeled with the number į, then the probability of encountering it on the įth cup is 1/100. This is because there is only one cup that is really salty out of the 100 cups in total.
Therefore, the probability that the įth cup you are given has really salty water is 1/100.

the perimeter of a rectangle is 24 inches the length and width are positive integers. how many distinct area can the rectangle have?
Answers
The 6 distinct possible areas can the rectangle have.
Given the perimeter of a rectangle, we can find the length (l) and width (w) using the formula:
The perimeter of a rectangle is defined as the sum of all the sides of a rectangle. In case of a rectangle, the opposite sides of a rectangle are equal and so, the perimeter will be twice the width of the rectangle plus twice the length of the rectangle and it is denoted by the alphabet “p”.
Perimeter of a rectangle = 2(Length + Width) square unitsLet us derive the formula for its perimeter and area
2l + 2w = 24
Solving for l and w, we get:
l + w = 12
l and w can be any combination of positive integers that add up to 12. The possible combinations are:
(1, 11), (2, 10), (3, 9), (4, 8), (5, 7), (6, 6)
Therefore, there are 6 distinct possible combinations of length and width for a rectangle with a perimeter of 24 inches, and therefore 6 distinct possible areas.

Answers
The local maximum and minimum values of the function are as follows: maximum at (smaller x value), minimum at (larger x value), and there are no saddle points.
To find the local maximum and minimum values of the function, we need to analyze its critical points, which occur where the partial derivatives are equal to zero or do not exist.
Let's denote the function as f(x, y) = -8 - 2x + 4y - x^2 - 4y^2. Taking the partial derivatives with respect to x and y, we have:
∂f/∂x = -2 - 2x
∂f/∂y = 4 - 8y
To find critical points, we set both partial derivatives to zero and solve the resulting system of equations. From ∂f/∂x = -2 - 2x = 0, we obtain x = -1. From ∂f/∂y = 4 - 8y = 0, we find y = 1/2.
Substituting these values back into the function, we get f(-1, 1/2) = -9/2. Thus, we have a local minimum at (x, y) = (-1, 1/2).
There are no other critical points, which means there are no local maximums or saddle points. Therefore, the function has a local minimum at (x, y) = (-1, 1/2) but does not have any local maximums or saddle points.

Answers
The appropriate test in this scenario is a one-sample t-test for a population mean.
The appropriate test for the researchers' hypothesis that the mean battery life of their new battery is greater than the known mean battery life of their older version would be a one-sample t-test for a population mean.This is because the researchers have a sample of the new batteries, and they want to compare the mean battery life of the new batteries to a known population mean (the mean battery life of the older version). Since the standard deviation of the population is not known, a t-test would be appropriate. Additionally, since the sample size is relatively small (n=32), a t-test is preferable over a z-test.Therefore, the appropriate test in this scenario is a one-sample t-test for a population mean.

We can reduce \(\frac{4}{8}\) to \(\frac{1}{2}\)
Our equation is now \(\frac{6}{d-6} =\frac{1}{2}\)
Now we can cross multiply
Definition - given an equation between two fractions or rational expressions, one can cross-multiply to simplify the equation or determine the value of a variable.
\(d-6=12\)
AddWe are adding because we want our variable to be on one side of the equation
\(d=18\)
To check we can show our equation but instead of d we have 18\(\frac{6}{18-6} =\frac{1}{2}\)

What does the Pythagorean Theorem and its converse state if each triangle is a right triangle?
Answers
The Pythagorean Theorem is a fundamental theorem in Euclidean geometry that relates to the sides of a right triangle.
The Pythagoras Theorem states that : in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of squares of lengths of other two sides.
Mathematically, the Pythagoras Theorem is written as:
⇒ c² = a² + b² ;
where c is = length of the hypotenuse, and a and b are the lengths of the other two sides of the right triangle.
The Converse of Pythagoras Theorem states that : If in a triangle, the square of the length of the longest side is equal to the sum of squares of lengths of other two sides, then triangle is a right triangle.
Both the Pythagorean Theorem and its converse apply only to right triangles, which are triangles that have a right angle .
