Answer 1
Answer:
1.
(A) y = 0.126X - 7.119
(B) 8.63
X = year, we subtract the year in the data from 1900;
So, for the years we have:
78,79,80,90,91,96,97,107,108,109
Using technology to fit the data above, the regression model obtained is;
y = 0.126X - 7.119
Where x = years
y = minimum hourly wage
The minimum hourly wage in 2025
Year = x = 2025 - 1900 = 125 years
y = 0.126(125) - 7.119
y = 8.631 Predicted Minimum hourly wage = 8.63
2.
(A) y = -0.4931x^2 + 23.3798x + 996.0289
(B) x = 20
y = -0.4931x^2 + 23.3798x + 996.0289
y = -0.4931(20)^2 + 23.3798(20) + 996.0289
y = -0.4931(400) + 467.596 + 996.0289
y = -197.24 + 467.596 + 996.0289
y = 1266.3849
Answer 2
Answer:
A) Y = 0.4931x2 + 23.3798 + 996.0289
B) X = 20

Is it me or does Y have multiple awnser. If not I need help to find the awnser. I know that x=54.
Answers
Answer:
y doesn't have multiple awnser, y = 47.5
Step-by-step explanation:
(y + 7) + (3y - 17) = 180
=> 4y = 190
=> y = 47.5
Answer:
47.5
Step-by-step explanation:
If r is parallel to s, then by the Alternate Exterior Angles Theorem:
x+56 = 3y-17. Additionally, (x+56)° is supplementary to (y+7)° because they make up a line.
So: 180 = x+56 + y+7 or
180-y-7 = x+56
Substitute into x+56 = 3y-17 so that 180-y-7 = 3y-17.
Solve for y to get y = 47.5

A bookstore in the mall is trying to determine how many mall shoppers are interested in purchasing
books as gifts. To obtain a random sample, the manager surveys every third person that enters the
bookstore.
Does the sample represent the population? Why or why not?
Select the option that correctly answers both questions.
O yes, because people who are already searching for books will give the best responses
O yes, because every third person that enters the bookstore is representative of all
shoppers in the mall
O no, because the manager needs to survey every person that enters the bookstore in
order to represent the population
O no, because people in the bookstore are interested in purchasing books, so they do
not represent all shoppers in the mall
Answers
Answer:
O no, because people in the bookstore are interested in purchasing books, so they do not represent all shoppers in the mall
Step-by-step explanation:
In the bookstore, the best method which the store keeper wanted to adopt is actually not a sample representation of the population. This is because, since it would be a survey of those that interested in purchasing books as gifts, it should be able to factor in other purchasers in the mall rather than those who purchase from the bookstore only.
Doing this, would help to give an accurate representation of both group in the survey.
If you were to flip a coin 10 times, do you think it would land on tails exactly 5 times? WHY or WHY NOT?
Answers
Answer:
I think that it could land on tails 5 times but most likely not.
Step-by-step explanation:
There are 11 different possible scenarios for the side of the coin flipped, and out of the 11 outcomes, only one of them results in 5 tails. Based on this, I believe that it is possible to land on tails exactly 5 times, but it would most likely not happen.

. Which set of dimensions below could be the dimensions of the prism?
6 by 8 by 3
5 by 6 by 7
2 by 7 by 11
Volume of a rectangular prism = base area x height
Base area = length x width
6 x 8 x 3 = 144 this is not equal to 154. This is not the correct dimension
5 x 6 x 7 = 210 this is not equal to 154. This is not the correct dimension
2 x 7 x 11 = 154 this is the correct dimension

The number of people who live in a unit of area is called the population density of the area. It usually given as people "per square mile" or "per square kilometer".
A map of the Orchard Hill Neighborhood is shown. The population of the Orchard Hill Neighborhood is 360 people. The lenght of each block is the same and the lenght of 20 blocks is 1 mile.
What is the area in square miles of Orchard Hill?
A. 0.35 square mile
B. 0.03 square mile
C. 0.15 square mile
D. 0.60 square mile
Answers
Answer: 0.03
Step-by-step explanation:
1 block = 1/20 mile = 0.05 miles
4(0.05) = 0.20
3(0.05) = 0.15
A=l•w=0.20(0.15)=0.03
The area of the Orchard Hill is 0.03 square miles if the length of each block is the same and the length of 20 blocks is 1 mile, option (A) is correct.
What is the area of the rectangle?
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
We have:
20 blocks = 1 mile
1 block = 1/20 miles = 0.05 miles
Length of 3 blocks = 3×0.05 = 0.15 miles
Length of 4 blocks = 4×0.05 = 0.20 miles
Area of the Orchard Hill = 0.15×0.20 = 0.03 square miles
Thus, the area of the Orchard Hill is 0.03 square miles if the length of each block is the same and the length of 20 blocks is 1 mile, option (A) is correct.

This arc has the same measurement as the central angle. The central angle is LON where O is the center of the circle.
Point M forms an angle that is 1/2 the central angle when M is on the circumference and opposite the 150o angle. Therefore M is the vertex of a 75 degree angle.
76x - 1 = 75 Add 1 to both sides.

The center of a circle is (3, 2) and a point on the circle is (5, -2). Find the radius and write the equation for the circle.
Answers
Answer:
r = [tex]2\sqrt{5}[/tex]
[tex](x - 3)^{2} + ( y - 2)^{2} = 20[/tex]
Is this a live test question or a homework question?
Step-by-step explanation:
the radius is the distance between (3, 2) and (5, -2)
[tex]r^{2}[/tex] = [tex]{(3 - 5)^{2} + (2 + 2)^{2} }[/tex]
= [tex](-2)^{2} + 4^{2}[/tex]
= 4 + 16 = 20
r = [tex]\sqrt{20 } = 2\sqrt{5}[/tex]
Equation of circle: [tex](x - 3)^{2} + ( y - 2)^{2} = 20[/tex]
Answer:
Radius: [tex]2\sqrt{5}[/tex]
Equation of circle: [tex](x-3)^2+(y-2)^2=20[/tex]
Step-by-step explanation:
The radius of a circle is equal to the distance between the center of the circle and any point on the circle. Therefore, we have:
[tex]r=\sqrt{(5-3)^2+(2-(-2))^2},\\r=\sqrt{2^2+4^2},\\r=\sqrt{20}=\boxed{2\sqrt{5}}[/tex]
The equation of a circle with radius [tex]r[/tex] and center [tex](h, k)[/tex] is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex].
What we know:
radius of [tex]2\sqrt{5}[/tex] center at [tex](3, 2)[/tex]
Substituting known values, we get:
[tex](x-3)^2+(y-3)^2=(2\sqrt{5})^2,\\\boxed{(x-3)^2+(y-2)^2=20}[/tex]
