Lisa and Alice are playing a game. Each player either receives or has to pay play money based on the results of their spin. The table lists how much a player receives or pays for various spins. What color has the greatest amount?
Red
Pays $5
Blue
Receive $4
Yellow
Pay $1
Green
Receive $3
Orange
Pay $2
Answers
Answer:
The amount in table as positive negative numbers: -5, 4, -1, 3, -2.
The spinner lands on red the change to Lisa's amount of money is -$5.
Step-by-step explanation:
Consider the provided table.
Part(A)
The table list how much a player receives or pays for various.
Paying some money is represented by a negative sign while receiving money is represented by a positive sign.
For red they needs to pay $5 which can be written as -5.
For blue they received $4 which can be written as 4.
For yellow they needs to pay $1 which can be written as -1.
For green they received $3 which can be written as 3.
For orange they needs to pay $2 which can be written as -2.
So, the amount in table as positive negative numbers: -5, 4, -1, 3, -2.
Part(B)
Now, we need to describe the change to Lisa’s amount of money when the spinner lands on red.
If spinner lands on red then she needs to pay $5.
Thus, if the spinner lands on red the change to Lisa's amount of money is -$5.

What is Trigonometric function?In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
What is Pythagorean theorem?In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.
Given,
a = 10, b = 2
Draw the figure using the given data
Apply Pythagorean theorem to find the third side or hypotenuse
[tex]c^{2}=a^{2} +b^{2}[/tex]
[tex]c^{2}=10^{2}+2^{2}\\c^{2}=100+4\\ c^{2}=104\\ c=\sqrt{104}[/tex]
c = 10.19 units
We know sin θ = Opposite side / Hypotenuse
Sin A = [tex]\frac{10}{10.19}[/tex]
sin A = 0.98
cos θ = Adjacent side / Hypotenuse
cos A = [tex]\frac{2}{10.19}[/tex]
cos A =0.20
tan θ = Opposite side / Adjacent side
tan A = [tex]\frac{10}{2}[/tex]
tan A = 5
Hence, the Exact values are follows:
sin A = 0.98
cos A = 0.20
tan A = 5

Suppose two angles in a coordinate plane, one measuring 80° and the other measuring 160°, were both rotated 180° about the origin and then
translated 40 units down. Which of these would be a measure of one of the resulting angles? Select all that apply
Answers
Answer:
120 and 40
Step-by-step explanation:
Given
[tex]\angle 1 = 160[/tex]
[tex]\angle 2 = 80[/tex]
Rotation = 180 degrees
Translation = 40 units down
Required
A measure of the resulting angles
180 degrees rotation
Rotation only affects the positioning of angles and does not change the measure of the angles.
So, the measure of both angles remain unchanged.
40 units down translation
This will reduce the measure of both angles by 40 degrees.
So:
[tex]\angle 1 = 160 - 40 = 120[/tex]
[tex]\angle 2 = 80 - 40 = 40[/tex]

A consumer group studied two different manufacturers of cars, J and K, to investigate differences in gas
mileage for cars made by the two manufacturers. For a similar type of car, a random sample of 15 cars
from J and a random sample of 12 cars from K were selected, and the gas mileages, in miles per gallon
(mpg), were recorded. The difference in the sample mean gas mileages was used to construct the 90
percent confidence interval (3.5,5.7).
Assuming all conditions for inference were met, which of the following is a correct interpretation of the
interval?
А
The probability is 0.90 that the difference in sample means for gas mileage for the two
car manufacturers is between 3.5 mpg and 5.7 mpg
B
The probability is 0.90 that the population mean difference in gas mileage for the two car
manufacturers is between 3.5 mpg and 5.7 mpg
About 90 percent of the differences in gas mileage for the two car manufacturers are
between 3.5 mpg and 5.7 mpg.
D
We are 90 percent confident that the difference in sample means for gas mileage for the
two car manufacturers is between 3.5 mpg and 5.7 mpg.
E
We are 90 percent confident that the population mean difference of gas mileage for the
two car manufacturers is between 3.5 mpg and 5.7 mpg.

Answer:
125 square meters
Step-by-step explanation:
Decomposition: Breaking up the shapes, finding their areas individually, and adding up their areas.
Area of a triangle: base * height * 0.5
First, let's look at the area of the top left triangle. The base is 5, while the height is 17. Thus, its area is
5 * 17 * 0.5 = 42.5
The bottom left triangle has a base of 5, and a height of 17, so its area is
5 * 17 * 0.5 = 42.5
The top right triangle has a height of 8 and a base of 5, so its area is
5 * 8 * 0.5 = 20
The bottom right triangle has a height of 8 and base of 5, so its area is
5 * 8 * 0.5 = 20
Now, add up all the areas.
42.5 + 42.5 + 20 + 20 = 125
Thus, the answer is 125 square meters.

[tex] \overrightarrow a= \bigg(\frac{5}{\sqrt 34},\:\frac{3}{\sqrt 34}\bigg)[/tex]
We have to show that [tex] \overrightarrow a[/tex] is an unit vector.
To show this, we will find the modulus of [tex] \overrightarrow a[/tex] and if its value is 1, it will be a unit vector.
So,
[tex] | \overrightarrow a| = \sqrt{\bigg(\frac{5}{\sqrt 34} \bigg) ^{2}+\bigg(\frac{3}{\sqrt 34}\bigg)^{2} } \\ \\ | \overrightarrow a| = \sqrt{\frac{25}{ 34} +\frac{9}{ 34} } \\ \\ | \overrightarrow a| = \sqrt{\frac{25 + 9}{ 34} } \\ \\ | \overrightarrow a| = \sqrt{\frac{34}{ 34} } \\ \\ | \overrightarrow a| = \sqrt{1} \\ \\ | \overrightarrow a| = 1[/tex]
Thus, [tex] \overrightarrow a[/tex] is a unit vector.

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is $ 40. For one performance, 25 advance tickets and 30 same-day tickets were sold. The total amount paid for the tickets was $1075 . What was the price of each kind of ticket?
Set up a set of 2 equations in 2 variables -
Let x = advance ticket cost and y = same-day tickets cost
Then
x+y=40 and
25x+30y=1075 >>>>> 5x+6y=215
x=40-y, so
5(40-y)+6y=215
