The other endpoint of the line segment is (13.8, 6).

The midpoint of a line segment is the point that lies exactly halfway between the two endpoints.

In this case, we have one endpoint, (6.9), and the midpoint (0,-6). Here is how we find the other endpoint:

To find the other endpoint, we need to subtract the midpoint from the given endpoint and then multiply by 2. The midpoint formula is given by:

M = (x1 + x2) / 2 and (y1 + y2) / 2

Where M is the midpoint, (x1, y1) and (x2, y2) are the coordinates of the two endpoints.

So, in our case, the other endpoint will be given by:

(x2, y2) = 2 * (6.9, 0) - (0, -6)

Expanding the expression, we get:

x2 = 2 * 6.9 - 0 = 13.8

y2 = 2 * 0 - (-6) = 6

Therefore, the other endpoint of the line segment is (13.8, 6).

To reach a temperature of 100 degrees the pizza would take 750 minutes.

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula.

Since the pizza was heated at a constant rate, we can model the experiment as a line, where the slope represents how fast the pizza was heated.

The slope is given as:

m = (y2 - y1)/(x2 - x1)

Let

(x1,y1) = (6, 40)

(x2,y2) = (8, 55)

m = (55 - 40) / ( 8 - 6 )

m = 7.5 degrees per minute.

The pizza heats up an average of 7.50 degrees per minute

To reach a temperature of 100 degrees the pizza would take:

(100)(7.50) = 750 minutes.

Hence, to reach a temperature of 100 degrees the pizza would take:

(100)(7.50) = 750 minutes.

The equation expressing the statement is A = k/r, where k is the constant of proportionality. Given that r = 3 and A = 7, the constant of proportionality can be found by rearranging the equation to k = A × r and substituting the given values to calculate: k = 7 × 3 = 21.

The statement "A varies inversely as r" can be expressed mathematically as an equation: A = k/r, where k is the constant of proportionality. This equation states that A is proportional to 1/r, meaning that as r increases, A decreases, and as r decreases, A increases. To find k, we can rearrange the equation to k = A × r and substitute the given values. In this case, if r = 3 and A = 7, then k = 7 × 3 = 21. Therefore, the constant of proportionality is 21. This equation can be used to determine the values of A, given a value of r, or the values of r, given a value of A. For example, if r = 4, then A = k/4 = 21/4 = 5.25. Conversely, if A = 10, then r = k/A = 21/10 = 2.1. This equation can be used to determine the values of A and r for any given situation.

The balance after 3 years can be calculated as follows:

I = P * r * t

Where:

I = interest

P = principal amount (2200)

r = interest rate (0.0295)

t = time in years (3)

So,

I = 2200 * 0.0295 * 3

I = 153.1

The final balance would be:

P + I = 2200 + 153.1

P + I = 2353.1

The final balance after 3 years is $2353.1, which is closest to option B ($2,329.80).

The correct option is (b) as the expected value and variance of daily revenue are 37.5 and 4.5 respectively.

What is meant by variance?

Consider the expected value to be the average value. The expected value of X when it is a discrete random variable is the exact mean of the relevant data.

The difference between the actual numbers and the average should be viewed as the variance. A greater range of values is indicated by a higher variance. A spread of measure for a random variable distribution that quantifies how much a random variable's values deviate from its expected value is called variance. Frequently, V(X) is used to represent the variance of random variable X.

Given,

  Cost of soft drink c = $0.30

   Expected value of the number of cans sold per day E(X) = 125

  Variance of number of cans sold per day V(X) = 50

 So,

    Expected value of daily revenue E(Y) = c *  E(X) = 0.3 * 125 = 37.5

  Variance of daily revenue V(Y) = c² * V(X) = 0.3² * 50 = 4.5

Therefore the expected value and variance of daily revenue are 37.5 and 4.5 respectively. The correct option is (b).

The given data sample of this year’s grants(given in thousands of dollars) in ascending order is :

5 22 23 25 26 27 50 70 90 100

The median of a data set is the middle value when the data is arranged in ascending or descending order. When number of values is even, there are two values in the middle, so we take the average of the two. So the median is

= (26 + 27)/ 2

The first quarter or the lower quartile (Q1), is the value under which 25%, that is first quarter of the data points are found when they are arranged in increasing order. Here Q1 is  0.25*10,  that is 2.5th value, but its not possible. So we should interpolate

Q1 = 22.5

Similarly third quartile, Q3 is the value under which 75% of the data points are found when they are arranged in increasing order. So

Q3 = (70 + 50)/2

Answer:

Step-by-step explanation:

A function is the inverse of another function if it "undoes" the original function. In other words, if you apply the original function to an input and then apply the inverse function to the result, you get the original input.

To find the inverse of a function, you can swap the input and output values of the original function, and then solve for the new input variable. For example, if the original function is f(x) = y, the inverse function would be f^-1(y) = x.

Given the function f(x) = -2, 3, 8, 13, it is not possible to find a simple algebraic inverse function for the given values of x = -1, 0, 1, 2. The inverse of a function is only well-defined if the function is one-to-one, meaning that for every output value, there is only one input value that maps to it. In this case, the function does not appear to be one-to-one, so it does not have an inverse function.

The sum of 45 terms of the arithmetic progression whose sum of 18 th and 28 th terms is 36 is given by 810.

Let the first term of the arithmetic progression be A and the common difference for the same be D.

So 18th term of the progression is = A + (18 - 1) D = A + 17D

28th term of the progression is = A + (28 - 1) D = A + 27D

Given that the sum of the 18th and 18th terms of the progression is 36.

So, A + 17D + A + 27D = 36

2A + 44D = 26

So now the sum of 45 terms of the arithmetic progression is given by,

= 45/2 [2A + (45 - 1)D]

= 45/2 [2A + 44D]

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality.

Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain.

Let x be an even number. Then, x = 2k for some integer k. The negative of x, -x, is equal to -2k, which is also an even number. Thus, the additive inverse of an even number is an even number.

An even number is any number that can be divided by 2 without any remainder, meaning that it can be written in the form x = 2k for some integer k. The additive inverse, or negative, of an even number, x, is -x. By definition, this is equal to -2k. As -2k can still be divided by 2 without any remainder, it is also an even number.

This can also be understood by looking at the positive and negative sides of the number line. If x is an even number, then it is two units away from 0. Therefore, -x is also two units away from 0, which means it is an even number. This shows that the additive inverse of an even number is an even number.

To prove this, we can look at a specific example. Let x = 8. Then, 8 = 2x4. The negative of 8, -8, is equal to -2x4, which is still an even number. Thus, this proves that the additive inverse of an even number is an even number.
