Answer:
The cost of the small package because...
Step-by-step explanation:
Cost of 1 postcards = $0.25
Cost of 4 postcards = 0.25 x 4 = 1
Cost of 1 letter = $0.44
Cost of 5 letters = 0.44 x 5 = 2.2
Cost of 1 large envelope = $0.80
Cost of 2 large envelopes = 0.80 x 2 - 1.6
Cost of 1 small package =$5.10
Since the cost of small package is highest
So, It will increase the mean
So, the cost of the small package will skew the mean

An Electric company attaches support cables to a light pole by 24 feet from the ground and 7 feet from the base of the pole.
How long is each support cable in feet?
Answer:
25
Explanation:
As can be seen from the figure:
The length of each support cable is:
√ 24² + 7² (pythagorean
theorem/
√576 +49
= √625
= √25²
25 feet
so the answer is 25

Which equation represents the graphed function?
A : y = -2x + 3
B : y = 2x + 3
C : y = 1/2x + 3
D : y = -1/2x + 3
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

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. Which conclusion can be made based on this information?
The total population mean must be much greater than $47,600 because there are more people in the total population.
The total population mean cannot be determined by such a small random sample.
The total population mean must be close to $47,600 based on statistical inference.
The total population mean must be much less than $47,600 because, out of a sample of 100, a few people with a very high mean income would skew the data.
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.
What is Mean?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.

Given that y = 6 + 4x-x^2express y in the form a.-(x + b)^2, where a and b are
integers. Hence or otherwise , write the coordinates of the turning point of y
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)

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.

On a coordinate plane, square p q r s is shown. point p is at (4, 2), point q is at (8, 5), point r is at (5, 9), and point s is at (1, 6). which statement proves that the diagonals of square pqrs are perpendicular bisectors of each other? the length of sp, pq, rq, and sr are each 5. the slope of sp and rq is negative four-thirds and the slope of sr and pq is three-fourths. the length of sq and rp are both startroot 50 endroot. the midpoint of both diagonals is (4 and one-half, 5 and one-half), the slope of rp is 7, and the slope of sq is negative one-sevenths.
A statement which proves that the diagonals of square PQRS are perpendicular bisectors of each other is: option D.
How to calculate the slope of a line?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.
