A computer manufacturer built a new facility for assembling computers. There were construction and new equipment costs. The company paid for these costs and made combined profits of $80 million after 4 years, as shown in the graph:
There is a graph of a line with Years on the x axis and Profits in millions on the y axis that passes through 1, negative 100 and 4, 80.
Which equation most closely represents the line depicted in the graph?
f(x) = 60x − 160
f(x) = −60x + 160
f(x) = −80x + 4
f(x) = 80x − 4
The equation that most closely represents the line depicted in the graph is; f(x) = 60x − 160
How to find the equation of a Graph?We're given a point of the graph (4, 80).
From the complete question seen online, we see that the profits increased $60 million per year. Thus, slope = 60.
Let us write the equation and find x and y intercepts.
y = 60x + b
Thus;
80 = 60*4 + b
80 = 240 + b
b = -160
Thus, the equation that most closely represents the line depicted in the graph is; f(x) = 60x − 160

Answer:
37
Step-by-step explanation:
Since the lines are parallel,
2x + 106 = 180
2x = 74
x = 37
Answer:
x = 37°
Step-by-step explanation:
∠ a = 2x [Corresponding angles]
106° + ∠ a = 180° [Angles on a straight line]
∴ 106° + 2x = 180°
⇒ 2x = 74°
⇒ x = 37°
People were asked if they prefer Pepsi or Coke. The results are in the table below.
Pepsi Coke
Female 23 44
Male 28 39
a) If two people are chosen, what is the probability that they both prefer Pepsi?
b) If one person is chose, find the probability that they are Female or prefer Coke.
Using it's concept, it is found that the probabilities are given as follows:
a) 0.1431 = 14.31%.
b) 0.7910 = 79.10%.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Item a:
The number of people is:
23 + 44 + 28 + 39 = 134.
The number of people that prefer Pepsi is:
23 + 28 = 51.
Hence, for the two people, the probability is:
p = 51/134 x 50/133 = 0.1431 = 14.31%.
Item b:
There are 23 + 44 = 67 females, and 39 males who prefer Coke, hence the probability is:
p = (39 + 67)/134 = 0.7910 = 79.10%.

Median weekly earnings for women with some college for an associate degree.
1980.......$231
2013.............$657
Using today's dollars, the data in the bar graph can be described by the mathematical model
W = 13n + 231,
Where W represents median weekly earnings n years after 1980.
Does the formula underestimate or overestimate the median weekly earnings in 2013? By how much?
Using the given linear function, the formula underestimates the median weekly earnings in 2013 by $3.
What is the linear function for the estimate?The function that estimates the median weekly earnings n years after 1980 is given by:
W = 13n + 231.
2013 is 2013-1980 = 33 years after 2000, hence the estimate is given by:
W = 13 x 33 + 231 = 660.
Since 657 < 660, the formula underestimates the median weekly earnings in 2013 by $3.

At least 3 favour wage and price controls?
Answer:
3/5

A movie theater has a seating capacity of 167. The theater charges $5.00 for children, $7.00 for students, and $12.00 for adults. There are half as many adults as there are children. If the total ticket sales was $ 1198, How many children, students, and adults attended?
Child attend:
Student attend:
Adult attend:
Answer:
Child attend: 58
Studen attend: 80
Adult attend: 29
Step-by-step explanation:
a + c + s = 167 Eq. 1
12a + 5c + 7s = 1198 Eq. 2
a = c/2 Eq. 3
a = adult attend
c = children attend
s = students attend
Replacing Eq, 3 in Eq. 2:
12(c/2) + 5c + 7s = 1198
6c + 5c + 7s = 1198
11c + 7s = 1198
7s = 1198 - 11c
s = (1198 - 11c) / 7 Eq, 4
Replacing Eq, 3 and Eq, 4 in Eq, 1
c/2 + c + (1198-11c) / 7 = 167
7c/14 + 14c/14 + 2(1198-11c)/14 = 2338/14
7c/14 + 14c/14 + 2396/14 - 22c/14 = 2338/14
7c + 14c + 2396 - 22c = 2338
7c + 14c - 22c = 2338 - 2396
-1c = -58
c = -58/-1
c = 58
from Eq. 3
a = c/2
a = 58/2
a = 29
from Eq. 4
s = (1198-11c)/7
s = (1198 - 11*58)/7
s = (1198 - 638) / 7
s = 560/7
s = 80
Check:
from Eq, 1
58 + 29 + 80 = 167
Drag each graph to show which transformation was applied to the original figure.
Each graph is the result of one transformation.
Transformation is a process in which the dimensions or orientation of a given plane shape is changed. The required answers are:
Graph 1: Reflection
Graph 2: Translation
Graph 3: Rotation
Graph 4: Rotation
Graph 5: Translation
Graph 6: Reflection
Transformation is the process in which the dimensions or orientation is a given shape is changed. The major types are reflection, dilation, translation, and rotation.
Reflection is a transformation method in which a given shape is flipped over a given reference point or line. Dilation is a transformation method that involves either increasing or decreasing the length of sides of a given shape.Translation is a transformation method that requires the movement of all points of a shape with respect to a given reference point or line.Rotation is a transformation method that involves the rotation of a given shape at a certain degree clockwise or counterclockwise.Thus the transformation process that was applied to the original figure for each graph is:
Graph 1: Reflection along the y-axis
Graph 2: Translation at 4 units in the -x direction
Graph 3: [tex]90^{o}[/tex] clockwise Rotation
Graph 4: [tex]180^{o}[/tex] clockwise Rotation

A livestock pen is built in the shape of a rectangle that is 3 times as long as it is wide. The perimeter is 56 feet. If the material used to build the pen is $1.50 per foot for the longer sides and $2.75 per foot for the shorter sides (the shorter sides have gates, which increase the cost per foot), find the cost to build the pen.
The cost of the shorter and longer side of the rectangular pen is $19.25 and $31.50 respectively.
Perimeter of rectangleWidth = xLength = 3xPerimeter = 56 feetPerimeter = 2(length + width)
56 = 2(3x + x)
56 = 2(4x)
56 = 8x
x = 56/8
x = 7
So,
Width = x
= 7 feet
Length = 3x
= 3(7)
= 21 feet
Cost of material used for the shorter side = $2.75 × 7
