A clothing company is interested in the relationship between the number of sales per month for its employees (y) and price. Based on the collected data, the least-squares regression line is ŷ = 9.74 + 4.89x, where x is the number of dollars by which price exceeds $25. Which of the following statements best describes the meaning of the slope of the least-squares regression line?
Question 3 options:
1)
For each increase in price of $1, the estimated number of sales per month increases by 4.89.
2)
For each increase in price of $1, the estimated number of sales per month increases by 9.74.
3)
For each increase of one sale per month, there is an estimated increase in price of $4.89.
4)
For each increase of one sale per month, there is an estimated increase in price of $9.74.
5)
The slope has no meaning because the units of measure for x and y are not the same.
Answer:
1) For each increase in price of $1, the estimated number of sales per month increases by 4.89
Step-by-step explanation:
Using linear function concepts, it is found that the statement that best describes the meaning of the slope of the least-squares regression line is:
1) For each increase in price of $1, the estimated number of sales per month increases by 4.89.Linear function:A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem, the equation is:
[tex]y = 9.74 + 4.89x[/tex]
The slope is of 4.89, which means that when x(number of dollars by which price exceeds $25) changes by 1, y(number of sales per month) increases by 4.89, hence option 1 is correct.

Given line 1, with coordinates (-7,-3) and (4,7), and line
2 with coordinates (7,-7) and (-3, 4), find the slope of line 2
Answer:
-11/10 (fraction) or -1.1 (decimal)
Step-by-step explanation:
The slope formula is m=(y2-y1)/(x2-x1)
x1 = 7
x2 = -3
y1 = -7
y2 = 4
So, it’s: (4 - (-7))/(-3-7)
= (4+7)/(-3-7)
= (11)/(-10)
= -11/10 or -1.1

The volume of a rectangular pyramid is 120 cm3. If the height of the base is 5 cm and the height of the pyramid is 12 cm, what is the length of the base of the pyramid?
Answer:
1. Volume of a cone: 1. V = (1/3)πr2h 2. Slant height of a cone: 1. s = √(r2 + h2) 3. Lateral surface area of a cone: 1. L = πrs = πr√(r2 + h2) 4. Base surface area of a cone (a circle): 1. B = πr2 5. Total surface area of a cone: 1. A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
Step-by-step explanation:
1. Volume of a cone: 1. V = (1/3)πr2h 2. Slant height of a cone: 1. s = √(r2 + h2) 3. Lateral surface area of a cone: 1. L = πrs = πr√(r2 + h2) 4. Base surface area of a cone (a circle): 1. B = πr2 5. Total surface area of a cone: 1. A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

Expression equivalent to a^2-144b^2
Answer:
(a - 12b)(a + 12b).
Step-by-step explanation:
a^2 - 144b^2
This is the difference of 2 squares identity:
a^2 - b^2 = (a - b)(a + b)
So for the given expression we have:
(a - 12b)(a + 12b).
- (as a is square root of a^2 and 12b is the square root of 144b^2.).

The ratio of the sides of a triangle is 2:5:3. If the perimeter of the triangle is 190 meters, what is the length of the longest side
Answer:
Step-by-step explanation:
Remark
Let x by the multiplying factor to make up 190 m.
2x + 5x + 3x = 190
10x = 190
x = 190/10
x = 19
The longest side is 5x
The longest side = 5 * 19 = 95

Supplementary angles add to 180
So, the angle supplementary to the angle of 112 degrees measures 68 degrees.
If these two lines are parallel, the angles are the same.
So, the triangle has angle measures: 2x, 68, and 68.
2x+68+68=180
2x=44
x=22
