I am trying to place the second point at 12.5. My graph only extend to -10.
We have to graph the line y = -2/5*x-5.
To do that, we need two points that belong to the line.
We can give two arbitrary values to x and calculate y using the equation of the line.
For example, for x=0, we get:
[tex]x=0\Rightarrow y(0)=-\frac{2}{5}\cdot0-5=-5[/tex]Then, the point is (0,-5).
Now, if we make x = 5, we can calculate y as:
[tex]x=5\Rightarrow y(5)=-\frac{2}{5}\cdot5-5=-2-5=-7[/tex]Then, we get the point (5, -7).
Using this two points we can graph the line as:
NOTE: In the case that the graph is limited to certain intervals in x or y, we have to try with different values of x until we find two points within the range shown by the graph.
In this case, (0,-5) and (5,-7) will be located within the range shown.

Warren flipped a coin and rolled a 20-sided number cube. What is the probability that his coin landed on tails and his number cube rolled a factor of 20? answer as a simplified fraction.
we have that
the probability that his coin landed on tails is
P=1/2
and
Factors of 20 are ----> 1,2,4,5,10,20
so
The probability that his number cube rolled a factor of 20 is
P=6/20=3/10
therefore
the probability that his coin landed on tails and his number cube rolled a factor of 20 is equal to
P=(1/2)*(3/10)

The probability that P solves the problem = 1/2
The probability that Q solves the problem= 1/4
The probability that both solve the problem = (1/2) x (1/4) = 1/8

A survey claims that the percent of a city's residents that favor building a new football stadium is likely between 52.3% and 61.7%. What was the sample proportion (what percent of the people in the sample survey said that they wanted to build a new stadium )?
The confidence interval for the sample proportion is calculated using the following formula:
[tex]\lbrack p\lbrack\text{hat\rbrack}\pm Z_{1-\frac{\alpha}{2}}\cdot\sqrt[]{\frac{p\lbrack hat\rbrack(1-p\lbrack hat\rbrack)}{n}}\rbrack[/tex]Where p[hat] represents the sample proportion. As you see you add/subtract the margin of error to the sample proportion to determine both bonds of the interval, which means that the sample proportion is in the middle of the interval.
The percent of residents in favor of building a new football stadium is between 52.3% and 61.7% → the sample proportion used to determine this interval is in the middle of both bonds. To calculate the said value you have to find the average of both values:
[tex]52.3\%The sample proportion used to estimate the interval was p[hat]=0.57
4.) Miles has saved about $41. He wants to buy an iPod for $129 in 4 months. How much moneydoes he need to save each month to buy the iPod?
Miles has saved about $41. He wants to buy an iPod for $129 in 4 months.
So first, we need to subtract the amount that he has already saved.
[tex]\$129-\$41=\$88[/tex]Now we need to divide this amount by 4 months.
[tex]\frac{\$88}{4}=\$22[/tex]Therefore, Miles needs to save $22 each month to buy the iPod.

[tex]\det A=a_1a_4-a_2a_3[/tex]Replacing we get:

[tex]A^{-1}=\frac{1}{(4)(1)-(-7)(-2)}\begin{bmatrix}{1_{}} & {7_{}} & {} \\ {2_{}} & {4_{}} & {} \\ {} & {} & {}\end{bmatrix}[/tex]Solving the operations:
[tex]A^{-1}=-\frac{1}{10}\begin{bmatrix}{1_{}} & {7_{}} & {} \\ {2_{}} & {4_{}} & {} \\ {} & {} & {}\end{bmatrix}[/tex]Or:

Selecting a green marble from a bag of 10 different coloredmarbles and then selecting a second green marble without puttingthe first backOD. Owning cows and living on a dairy farm
Independent events are events where one event occurring or not does not affect whether the other one happens.
Pulling two cards out of a deck of cards, when you don't replace the first card, or pulling two marbles from a bag, where you don't replace the first marble, are not independent. By removing the first card/marble, you've change the situation for the second draw.
Using a spinner and rolling a die are totally independent, since they are different objects and what happens on one does not impact what will happen on the other.
And if you live on a dairy farm, that creates a better chance of being involved with dairy production and cows, so those are not independent.
Option A has two independent events.
Which value of x makes the equation 4x+9=x+6 true?
Answer:
x=-1
Explanation:
Given the equation:
[tex]4x+9=x+6[/tex]First, we subtract 9 from both sides.
[tex]\begin{gathered} 4x+9-9=x+6-9 \\ 4x=x-3 \end{gathered}[/tex]Next, we subtract x from both sides.
[tex]\begin{gathered} 4x-x=x-x-3 \\ 3x=-3 \end{gathered}[/tex]Finally, we divide both sides by the number beside x which is 3.
[tex]\begin{gathered} \frac{3x}{3}=\frac{-3}{3} \\ x=-1 \end{gathered}[/tex]The value of x that makes the equation true is -1.
#3 What does the slope tell you about the rate of change in elavation during Ryan’s uphill climb? What was the total elevation change?
Solution
Step 1:
Let find the slope
[tex]\begin{gathered} Slope\text{ = }\frac{Change\text{ in elevation}}{Change\text{ in time}} \\ S\text{lope = }\frac{1500\text{ - 300}}{120\text{ - 0}} \\ Slope\text{ = }\frac{1200}{120} \\ Slope\text{ = 10} \end{gathered}[/tex]His answer and these calculations are correct because he followed all the steps correctly to findtwo points' slope.
Step 2; First we need to determine how many different slopes there are on the given graph. Assume time is represented in minutes and distance is represented in meters. There are three in this graph, one goes from 0 minutes to 120 minutes and the second one is from 120 minutes to 150 minutes. The final one goes from 150 to 180 minutes. To calculate the speed of traveling we convert the distance traveled into a constant period of time i.e. an hour.
Question1
What does the slope tell you about the rate of change in elavation during Ryan’s uphill climb?
The first slope(line) tell us that Ryan travels from 300 meters to 1,500 meters from 0 minutes to 120 minutes.
meaning he traveled 1200 meters in 120 minutes which is equal to 600meters per hour or 0.6km/h.
In the second line, Ryan's travels no distance from 120 minutes to 150 minutes. So he was at rest and did not travel in this period of time.
In the third line (slope) , Ryan travels from 1,500 meters to 300 meters from 150 minutes to 180 minutes. So he traveled 1,200 meters in 30 minutes. This equals 2,400 meters per hour, which is 2.4 kilometers per hour.
Final answer
The slope tell you about the rate of change in the elevation during Ryan's uphill climb that:
Ryan ascends at a speed of 0.6 kilometers per hour for the two hours, takes rest for half an hour and then descends at 2.4 kilometers per hour for the half-hour.
Question 2
What is the total elevation change?
Elevation gain is the total amount you will climb in a day, and elevation loss is the total amount you will descend in a day. For example, if you climb 1000 feet, descend 500 feet, and then climb an additional 300 feet, the elevation gain would be 1300 feet and the elevation loss would be 500 feet.
From the graph?
Elevation gain = 1200 feet
Elevation loss = 1200 feet

As per the unitary method, the number of democrats are 53 and the number of republicans are 47.
Unitary method:
Unitary method is the process of finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given,
The U.S senate has 100 members. after a certain election, there were 6 more democrats than republicans, with no other parties represented.
Here we need to find the number of democrats and the number of republicans.
Let us consider the number of Republican's be "x"
And then the number of Democrats is "x+6".
We know that the total number of members in the senate is 100.
So, it can be written as
x + (x + 6) = 100
2x + 6 = 100
2x = 100 - 6
2x = 94
x = 94/2
Then the value of x is,
x = 47
Therefore, there are 47 republicans in the senate then the number of democrats is
x + 6 => 47 + 6 => 53
