The total population mean must be close to $47,600 based on statistical inference.

The entire population mean must be close to $47,600. Then the correct option is C.

The mean is the simple definition of the average of a bunch of numbers. In statistics, one of the markers of central tendency is the mean.

The average is referred to as the arithmetic mean.

It's the ratio of the number of real observations to the total number of observations.

The owners of a manufacturing company conducted a survey to determine the mean income of the customers who prefer the company’s brand of clothing.

From a random sample of 100 customers, it was determined that their mean income was $47,600.

Based on statistical analysis, the entire population mean must be close to $47,600.

A statement which proves that the diagonals of square PQRS are perpendicular bisectors of each other is: option D.

Mathematically, the slope of a line is given by the following formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

For line RP, we have:

[tex]Slope = \frac{9\;-\;2}{5\;-\;4}\\\\Slope = \frac{7}{1}[/tex]

Slope RP = 7.

For line SQ, we have:

[tex]Slope = \frac{6\;-\;5}{1\;-\;8}\\\\Slope = \frac{1}{-7}[/tex]

Slope SQ = negative one-sevenths.

For the midpoint, we have:

In order to determine the midpoint of a line segment with two (2) endpoints, we would add each point together and divide by two (2).

Midpoint on x-coordinate = (8 + 1)/2 = 9/2 = 4.5.

Midpoint on y-coordinate = (9 + 2)/2 = 11/2 = 5.5.

In conclusion, a statement which proves that the diagonals of square PQRS are perpendicular bisectors of each other is that the midpoint of both diagonals is (4.5, 5.5), the slope of RP is 7, and the slope of SQ is negative one-sevenths.

Answer:

2, 16, 18.

Step-by-step explanation:

The first number might be 4 , 9, 16 or 25.

The other 2 numbers are factors of 18 so could be:

2, 3, 6, 9 or 18.

If square no. = 4 then sum of other 2 = 32 but no 2 numbers will fit the required result.

If it is 9, the sum = 27 then 9 and 18 will fit but that makes 2 square numbers  so this is not the answer.

If square no. = 16, the sum of other 2 is 20. 2 and 18 will fit this.

Answer:

6 + 4x − x² = 10 − (x − 2)²

the turning point : (2 , 10)

Step-by-step explanation:

6 + 4x − x² =  − x² + 4x + 6

                 = − (x² − 4x) + 6

                 = − (x² − 4x + 4 − 4) + 6

                 = − [(x − 2)² − 4] + 6

                 = − (x − 2)² + 4 + 6

                 = − (x − 2)² + 10

                 = 10 − (x − 2)²

Then the turning point of y is (2 , 10)

Step-by-step explanation:

divide 14 by 7 to get 2. IT is 2 tests a week so multipy 7 by 2 to get 14 then just add 2 to get 16. you added two meaning you added a week because each week is two tests so the answer will be 8 weeks.

Tim have to attend a total of 8 weeks this quarter before he will have taken a total of 16 quizzes.

The unitary method is a process for solving a problem by first finding the value of a unit, and then finding the necessary value by multiplying the single unit value.

According to the problem,

Tim took 14 quizzes over the course of 7 weeks.

∴ Tim can take 1 quiz over the course of [tex]\frac{7}{14}[/tex] weeks

Tim can take 16 quizzes over the course of [tex](\frac{7}{14})[/tex] x 16 weeks = 8 weeks

∴ Tim can take 16 quizzes over the course of 8 weeks.

Answer:

y = - 2x + 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1, 1) ← 2 points on the line

m = [tex]\frac{1-3}{1-0}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2

the line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = - 2x + 3 ← equation of line
