.. You can tell from the point (3, 9) that the only viable choice is selection D.
Center section:
.. When you extend the graph to the y-axis, you see the y-intercept is 10. The slope is negative, so selection B is appropriate.
Right section:
.. The line goes up 3 grid points for each 2 to the right, so the slope is 3/2. In point-slope form the equation of that line can be written as
.. y = (3/2)(x -6) +4 = (3/2)x -9 +4 = (3/2)x -5 = (3x -10)/2 . . . . . selection C

If you take a certain number 2.5 times then add 1.75 and divide the result by 0.8, you’ll get 37.5. What was the original number?
Answers
Answer:
The original number is 11.3
Step-by-step explanation:
Let the number is x and then we form the equation to solve it for the value of x.
1- Number is multiplied by 2.5 then it becomes = 2.5x
2- Then we add 1.75 to the expression then new expression will be = 2.5x + 1.75
3- We divide the result by 0.8 then expression will be = [tex]\frac{2.5x + 1.75}{0.8}[/tex]
4- Now the final expression is equal to 37.5 so the equation will be
[tex]\frac{2.5x + 1.75}{0.8}[/tex] = 37.5
Now we multiply 0.8 in both the sides of the equation
[tex]\frac{2.5x + 1.75}{0.8}[/tex]×0.8 = 37.5×0.8
2.5x + 1.75 = 30
2.5x = 30 - 1.75
2.5x = 28.25
x = 28.25/2.5 = 11.3

What is the interquartile range of the data set? Enter the answer in the box. Key: 1|5 means 15
Answers
28, 40, 43, 43, 45, 50, 50
Total number of values = 7
Since the number of values is odd, the median will be the middle value i.e. 4th value which is 43. Median divides the data in two halves:
1st Half = 28, 40, 43
2nd Half = 45, 50, 50
Q1 or the First Quartile is the middle value of the lower or 1st half which is 40.
Q3 or the Third Quartile is the middle value of the upper or second half, which is 50.
IQR or the Inter Quartile Range is the difference of Q3 and Q1.
So, IQR= Q3 – Q1 = 50 – 40 = 10
Thus, IQR for the given data is 10
The interquartile range(IQR) of the data set is:
10
Step-by-step explanation:The data points according to the stem and leaf plot are as follows:
28 40 43 43 45 50 50
We know that the median of the data is the central tendency of the data and always lie in the middle of the data.
Here looking at the data we have:
Median= 43
Similarly the lower set of data is:
28 40 43
Hence, the first quartile or the lower quartile i.e. [tex]Q_1[/tex] is the median of the lower set of data.
Hence,
[tex]Q_1=40[/tex]
Similarly, the upper set of data is:
45 50 50
Hence, the upper quartile or the third quartile i.e. [tex]Q_3[/tex] is the median of the upper set of data.
Hence,
[tex]Q_3=50[/tex]
The interquartile range(IQR) is calculated as:
[tex]IQR=Q_3-Q_1\\\\IQR=50-40\\\\IQR=10[/tex]

the measure of an angle is 34 degrees what is the measure of its supplement
Answers
We would have to remember that (supplement) angles are always [tex]180[/tex]°. So, sense this would be the case, if that measure of an angle is 34 degrees, we would then obviously subtract it then.
[tex] \left[\begin{array}{ccc}\boxed{\boxed{180 - 34}}\end{array}\right] = \left[\begin{array}{ccc}\boxed{\boxed{146 \ would \ be \ the \ answer}}\end{array}\right] [/tex]
Hope this helps you dear!
The measure of the supplement angle is 146 degrees.
What are supplementary angles?The supplementary angles is defined as when pair of angles addition to 180° then they are called as supplementary angles. There are two types of supplementary angles.
What are Adjacent angles?Adjacent angles is the type of supplementary angles. Adjacent angles have a common side and vertex, for example a corner point. Their points do not overlap in any way. In other terms, adjacent angles is pair of two angles next to each other
Given that the measure of an angle is 34 degrees
Let x = the measure of the supplement angle.
Two angles whose sum is 180 degrees are supplementary.
∴ x + 34 = 180
Then, (180 -34 ) is the supplement of that angle.
The measure of the supplement angle = 146 degrees
Hence, the measure of the supplement angle is 146 degrees.

Answers
Since step 1 is 63,360 and each is 6 higher.
First I will try...
Altitude = 63,360 + 6x
Lets check it with step 1 ...
= 63,360 + 6(1)
= 63,366
wrong.
6 too high
So the formula would be
Altitude = 6x + 63,354
Lets test for known step 5 which the sequence says will be 63,384 ...
= 6(5) + 63,354
= 30 + 63,354
= 63,384
Looks good !
Now...
For step 55 just plug in 55 as X to solve.
= 6(55) + 63,354
then simplify

Maggie and her friend visit a beach that has a shoreline 2 2/5 kilometers long. They walk along 2/3 of it. How many kilometers of the beach shoreline do they walk?
Answers
If we want to find 2/3 of 2 2/5, we can multiply the fractions together.
[tex] \frac{2}{3} * 2 \frac{2}{5} [/tex]
= [tex] \frac{24}{15} [/tex]
= [tex] \frac{8}{5} [/tex]
= [tex]1 \frac{3}{5} [/tex]
This means that Maggie and her friend have walked [tex] 1 \frac{3}{5} [/tex] kilometers of the beach shoreline.
To find out how many kilometers of the beach shoreline Maggie and her friend walk, we need to multiply the length of the shoreline by the fraction they walk along. Maggie and her friend walk 8/5 kilometers of the beach shoreline.
Explanation:To find out how many kilometers of the beach shoreline Maggie and her friend walk, we need to multiply the length of the shoreline by the fraction they walk along.
First, we need to convert the mixed number 2 2/5 to an improper fraction. We can do this by multiplying the whole number (2) by the denominator (5) and adding the result to the numerator (2), then putting the new numerator over the denominator. So, 2 2/5 is equal to (2 * 5 + 2) / 5 = 12/5.
Next, we can multiply the length of the shoreline (2 2/5) by the fraction they walk along (2/3). Multiply the whole number and numerator separately, then add the products and put the result over the denominator.
So, (12/5) * (2/3) = (12 * 2) / (5 * 3) = 24/15 = 8/5.
Maggie and her friend walk 8/5 kilometers of the beach shoreline.

you suspect that an unscrupullous employee at a casino has tampereed with a die. that is, he is using a loaded die. In order to test this claim you roll it 258 times and obtain the folllowing frquencies Category 1 2 3 4 5 6 Frequency 48 52 51 34 48 25 a. Choose the approp. alternative hypotheses to test if the population proportion differ a/all population proportion differ from 1/6 b/ Not ll population proportion are equal to 1/6 b-1 calculate the value of the test statistic(round to at last 4 decimal places) b-2 Approx. the p-value c. at the 10% signifigance level. can you conclude that the die is loaded?
Answers
Therefore for your alternative hypothesis it would need to be: Not all population proportions are equal to 1/6.
b-1. Since we have 6 different outcomes, we will use the chi square test to evaluate the hypothesis. The test statistic is computed by getting the summation of [tex] \frac{ (observed-expected)^{2} }{expected} [/tex] for all the 6 outcomes. In our case the expected proportion would be 1/6 or 0.1667 and the observed values would be the proportions from the 6 outcomes.
[tex] X^{2} = \frac{ (0.1860-0.1667)^{2} }{0.1667} +\frac{ (0.2016-0.1667)^{2} }{0.1667}+\frac{ (0.1977-0.1667)^{2} }{0.1667}[/tex]
[tex]+\frac{ (0.1318-0.1667)^{2} }{0.1667}+\frac{ (0.1860-0.1667)^{2} }{0.1667}+\frac{ (0.0969-0.1667)^{2} }{0.1667}=0.0541[/tex]
ANSWER: The test statistic is 0.0541
b-2. For this problem we just imagine the chi square distribution and the fact that our test statistic is so close to zero so the p-value must be so much greater than 0.10.
Based on other resources, there are choices to this problem so we just choose the option similar to the one we just described.
ANSWER: p-value > 0.10
c. Since the p-value we estimated above is greater than 0.10, we do not reject the null hypothesis. This means that there is NOT enough evidence to reject the fact that the die is a fair die.
ANSWER: No, we cannot conclude that the die is loaded.

= Factoring the expression (r²+7r+10) we get (r+2)(r+5)
Then multiply it with the other numerator, we get
= (r+2)(r+5)(3(r-10)
Then we factorise
= (r²-5r-50) = (r+5)(r-10)
Multiplying it with the other denominator, we have;
= 3(r+5)(r-10)
Therefore dividing
(r+2)(r+5)(3(r-10)/(3(r+5)(r-10) we get;
= r+2
Therefore, the correct answer is r+2
If you eliminate the (r+5),(r-10) and 3, then what is left is (r+2). The answer is r+2.

Formulate a system of equations to represent this situation, with f = the amount of money that Frank spent and r = the amount of money that Rachel spent. Frank and Rachel spent a total of $15.75. If Rachel spends twice as much money as Frank, how much money did they each spend?
A)
B)
C)
D)
Answers
Rachel and Frank spends $10.5 and $5.25 respectively.
It is given to us that
f is the amount of money that Frank spent and
r is the amount of money that Rachel spent.
Frank and Rachel together spent a total of $15.75.
Rachel spends twice as compare to Frank
The equation that represents this situation:
1. f + r = $15.75
2. r = 2f
Substituting r = 2f in equation 1.
f + r = 15.75
f + 2f = 15.75
3f = 15.75
f = 5.25
Substituting f = 5.25 in equation 2.
r = 2f
r = 2(5.25)
r = 10.5
Thus, Rachel spends $10.5 and Frank spends $5.25.
