What is the equation of a line that contains point(-2,8) and has a slope of two

We need 42 minimum number integers from 0 to 80 that must be selected in order to be sure of getting at least one that is odd.

We need Pigeonhole Principle which states,

The pigeonhole principle is one of the simplest but most useful ideas in mathematics, and can rescue us here. A basic version says that if (N+1) pigeons occupy N holes, then some hole must have at least 2 pigeons. Thus if 5 pigeons occupy 4 holes, then there must be some hole with at least 2 pigeons.

We know that there are 40 odd integers 1, 3, 5, 7, ....79 and 41 even integers 0, 2, 4, 6, .....80 from 0 to 80 .

So, at most, 41 integers picked out of them. If we pick one more integer after picking all of these then it must be odd integer according to Pigeonhole  Principle. Therefore, we need to at least one more integer from 0 through 80 to be sure that there is at least one odd integer.

So, in total we need to pick at least 41 + 1 = 42 integers from 0 to 80 to be sure of getting at least one that is odd.

The Measure for the Following

m< 1= 72 degree.

m< 2= 72 degree.

m< 3= 58 degree.

Horizontal Angles (Vertically Opposite Angles) The opposing angles created by the junction of two lines are known as vertical angles or vertically opposite angles. A pair of angles that are vertically opposed to one another are always equal.

Given:

In Δ MQP and Δ OQN

<3 = 58 (Alternate Interior Angle)

Now, In Δ OQN Using Angle Sum Property

<2+ <3 + 50= 180

<2 + 58+ 50 = 180

Answer:

The solution to this equation is x=4 (or A)

Step-by-step explanation:

First, you want to remove the parentheses from the equation and distribute 2 through the parentheses:

4x+2x+12=36

Then you collect like terms:

6x+12=36

Then you move the constant to the right-hand side and change its sign:

6x=36-12

Then you subtract the numbers:

6x=24

Then you divide both sides of the equation by 6, which gives you your solution:

x=4

Answer:

The correct answer is A. hire employees.

During a boom, or an economic expansion, businesses typically experience increased demand for their products and services. This often leads to higher profits and sales, and as a result, many businesses will choose to hire additional employees to help meet the increased demand. Hiring employees allows businesses to increase their production and sales, and it can also help them to capitalize on opportunities for growth and expansion.

The other answer choices, cutting jobs (B) and saving cash (C), are not typically associated with a boom. Cutting jobs would be more likely to occur during a recession or a downturn in the economy, when businesses are trying to reduce costs and improve their bottom line. Saving cash, on the other hand, is something that businesses might do during any economic conditions, as it can help them to build up a financial cushion and prepare for unexpected events. However, during a boom, businesses are more likely to focus on expanding their operations and taking advantage of the increased demand for their products and services.

Step-by-step explanation:

Answer:

A.

Step-by-step explanation:

It seems like the most logical answer, as boom usually means it's doing well. When a business is doing well I doubt they would want to cut jobs or have to be worried about saving their extra cash.

Translate vertex W to vertex M. Next, reflect WXY across the line containing line segment WX is MXY

The intersection of two lines, two line segments, or any suitable combination of rays, segments, and lines that results in two straight "sides" coming together at one point is known as an angle's vertex. 1. Translate vertex W to vertex M: Move point W to the right by 4 units, creating point M.

2. Reflect WXY across the line containing WX: Create a line perpendicular to WX, and reflect WXY across it. The resulting figure is MXY.

Answer:

g(f(x)) = x² + 1.

Step-by-step explanation:

To evaluate g(f(x)), we need to first evaluate f(x) and then plug the result into g(x). Since f(x) = x² - 1, we have g(f(x)) = g(x² - 1). Plugging this into g(x), we get g(x² - 1) = (x² - 1) + 2. So the final result is g(f(x)) = x² + 1.

Here's a step-by-step breakdown:

Note that this is only the case if f(x) and g(x) are defined for all values of x. If either function is only defined for certain values of x, then the result of g(f(x)) will depend on the specific input value used.

Potential type of statistical error would be Type I statistical error.

What is statistical error?

The term "error" (also known as "statistical error") refers to the discrepancy between a value obtained through a data gathering procedure and the population's "actual" value. The data are less representative of the population the higher the inaccuracy. Both sampling error and non-sampling error can have an impact on data.

Given that:

two sided test of hypothesis is giving 0.05 level of significance.

and statistic resulting from the analysis was 1.23.

According to statistic result,

the results are not statistically significant because the p-value > 0.05.

A set of statistics exam scores are normally distributed with a mean of 76. 5576. 5576, point, 55 points and a standard deviation of 555 points. 28.34% proportion of exam scores are between 797979 and 86. 586. 0586..

A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. In contrast, a high or low standard deviation indicates that the data points are, respectively, above or below the mean. A standard deviation that is close to zero implies that the data points are close to the mean.

Given,

Mean = 76.55

Standard deviation = 5

To calculate this, we first need to get the Z score mathematically

Z = X - mean/standard deviation

For the 79,

Z = 79 - 76.55/5

Z = 0.49

For the 86.05

Z = X - mean/standard deviation

Z = 86.05 - 76.55/5

Z = 1.9

So, we have

P(0.49 < Z < 1.9)

P( Z < 1.9) - P( Z < 0.49)

Using the table of standard score probability

P(Z < 1.9) = 0.9713

P( Z < 0.49) = 0.6879

P( Z < 1.9) - P( Z < 0.49)

0.9713 - 0.6879

0.2834

The approximate probability that the next 100 sunday customers will spend an average of at most $28 is 0.97725

This theorem limits the central value (mean) of a sample measure to the mean value of the population from which the sample was drawn. There are two versions of this set, average and ratio respectively. This is true only if each sample is the same size and that size matters.

We have given that,

Mean , μ = $32

Standard deviations, σ = $20

sample size, n = 100

The probability that the test 100 sunday customers will spend on average of at most $28.

Using formula,

Standard error = 20/Sqrt(100) = 2

Test- statistic, Z = (x -μ)/S.E

here we have, x = 28 , S.E = 2 , μ = 32

=> Z = ( 28 - 32)/2 = - 4/2 = -2

Now, the approximate probability value, P(X≤ x )

is P(X≤ 28) = P(X - μ / S.E < 28- 32/2) = P(Z≤ -2)

If PQ=3x+8 and QR=2x + 17, the value of x is 31.

When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°. The linear pair postulate or linear pair theorem in mathematics states the same thing mathematically. The sum of the measurements of two angles that make up a linear pair is 180°.

A minimax problem minimizes the maximum value of a number of decision variables and the maximin problem maximizes the minimum value

We know that a minimax problem minimizes the maximum value of a number of decision variables. It is sometimes applied to minimize the possible loss for a worst case (maximum loss) scenario. On the other hand a maximin problem maximizes the minimum value. Generally it is used to maximize the minimum objective (such as profit or revenue) for all potential scenario.

To solve the  optimization problem for maximum :

First we find the derivative of the function.

Set the derivative equal to 0 and solve for x. This gives the x-values of the maximum and minimum points.

Now substitute those values of x back into the function to find the corresponding values of y. This will give the maximum and minimum points of the function.

Therefore, the maximin problem maximizes the minimum value  of a number of decision variables.

Then the prediction of the city is given by the one whose prediction for a input of 2800 square feet gives the least residual relative to 280, that is, the value that has the least absolute difference relative to 280.

For Smaville, the equation is given as follows:

p = 150 + 0.041a.

Hence the estimate of the cost for a estate with 2800 square feet is of:

p = 150 + 0.041(2800) = 264.8.

For Fancyville, the equation is given as follows:

p = 250 + 0.198a
