Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
Answers
The slope of the line = rise/run = 2/3.
How to Determine the Slope of a Line?To determine the slope of a line, we can find the ratio of the rise of the line to that of its run.
Therefore, slope (m) of a line = rise/run.
Rise = vertical distance across the line
Run = horizontal distance across the line
In the graph given, we have:
Rise is the blue line = 6 units
Run is the red line = 9 units
Slope of the line (m) = 6 units/9 units
Slope of the line (m) = 2/3
Therefore, In simplest form, the slope of the line = rise/run = 2/3.

in a recently published sociology article about transportation patterns, a sociologist studied whether families rely on their own transportation instead of public transportation. let the mean number of cars owned by a family be μ. if the sociologist wanted to know if families own, on average, more than 3 cars, what are the null and alternative hypotheses?
Answers
The null hypothesis is [tex]H_0:\mu=3[/tex] and the alternative hypothesis is [tex]H_1:\mu > 3[/tex]
There are two hypothesis considered in a statistical test. They are:
Null hypothesis ([tex]H_0[/tex])Alternative hypothesis ([tex]H_1[/tex])Formulation of null and alternative hypothesis are considered as the first step of a statistical procedure. The whole procedure, then, continues on testing whether to accept or reject these hypotheses.
Null Hypothesis is the actual hypothesis which is tested. Alternative hypothesis, as its name suggests, is the hypothesis accepted when the null hypothesis is rejected in the test carried out.
Here the sociologist is carrying out the test on the mean number of cars, [tex]\mu[/tex].
So to check whether the families own more than 3 cars in average,
the null hypothesis will be ,[tex]\bold{H_0:\mu=3}[/tex]
and the alternate hypothesis will be, [tex]\bold{H_1:\mu > 3}[/tex]
So if the null hypothesis is rejected, then there is the possibility for only more than 3 cars in average.

Step-by-step explanation:
To find the average rate of change from two points: [a, b] we generally use the slope equation, which can be represented as: [tex]\frac{f(a)-f(b)}{a-b}[/tex]
So here let's first calculate f(3) and f(5)

If triangle GHJ is isosceles find the value of x
Answers
Answer:
x = 5
Step-by-step explanation:
Because an isosceles triangle's angles will always add up to 180, it's quite simple plugging in angle J into a formula to find our answer.
Before we begin, recall that the bottom two angles of an isosceles triangle are equal to the other. Thus:
Unknown angle (H) = 14x+1
So...
38 + 14x + 1 + 14 x + 1 = 180
40 + 28x = 180
-40 -40
28x = 180
28x/28 = 180/28
We get:
x = 5
Answer:
[tex]x = 5[/tex]
Step-by-step explanation:
Note that:
Base Angles Of An Isosceles Triangle Are Equal.Calculating For the Value Of X
Since Base Angles are Equal(14x + 1)° + (14x +1)° +38° = 180°
Removing Brackets14x + 1 + 14x + 1 + 38 = 180°
28x + 2 + 38 = 180°
28x + 40 = 180°
collecting like term28x = 180 - 40
28x = 140
x =5
Therefore the value of x is 5

The wavelength of the color red is about 6.5×10^−9 m. The wavelength of the color blue is about 4.75×10^−9 m. Show that the wavelength of red is longer than the wavelength of blue.
Pls answer asap 100 points
Answers
Explanation:
We can substract the wavength of the violet light to the wavelength of the red light:
(6.5 x 10^-7 m) - (4.0 × 10^-7 m) = 2.5 x 10^-7 m
This is the difference between this two values of wavelength.
So the wavelength of red light is 2.5 x 10^-7m longer than violet light.
Step-by-step explanation:
To tell if something is longer than another object is to find the difference between the two objects.
If the difference is < 0, then the object is shorter
If the difference is = 0, then the objects are equal in length
If the difference is > 0, then the object is longer
[tex]6.5 * 10^{-9}[/tex] - [tex]4.75 * 10^{-9}[/tex] = [tex]1.75*10^{-9}[/tex]
The difference is > 0, so the wavelength is longer.

What if the large ferris wheel makes one revolution in 10 seconds and the small wheel makes one revolution in 7 seconds, how many revolutions will each ferris wheel need to complete before you and your sister are at the bottom at the same time?
Answers
For you and your sister to reach bottom at the same time, the large Ferris wheel has to take 7 revolutions and the small Ferris wheel has to take 10 revolutions.
Time taken by the large Ferris wheel to complete 1 revolution = 10 seconds.
Time taken by the small Ferris wheel to complete 1 revolution = 7 seconds.
For them to reach bottom at the same time, we need to calculate their least common multiple.
LCM of 10 and 7 will be :
LCM = 10 × 7 = 70 seconds.
Revolutions taken by large Ferris wheel will be = 70 / 10 = 7 revolutions.
Revolutions taken by small Ferris wheel will be 70 / 7 = 10 revolutions.

Mr. Zuro finds the mean height of all 16 students in his statistics class to be 67.0 inches. Just as Mr. Zuro finishes explaining how to get the mean, Danielle walks in late. Danielle is 63.6 inches tall. What is the mean height of the 17 students in the class?
Answers
Answer:
66.8 inches
Step-by-step explanation:
The mean height of 16 students is 67.0"
Total height of 16 students = 67 x 16 = 1,072"
When Danielle walks into the class an additional height of 63.6" is added to the total and the new total becomes 1072 + 63.6 = 1135.6"
Since there are now 17 students, mean = 1135.6/17 = 66.8"

Now it is given that,
Pages typed by Ingrid = 3
Pages typed by Tanya = 4
So, the ratio of pages, Ingrid : Tanya = 3 : 4
So, If the grid and tanya start typing at the same time Ingrid has typed 11 pages
Thus, dividing the ratio be 3 we get,
3 : 4 = 1 : 1.33
Now for 11 pages multiplying 1.33 with 11 we get,

You average 55 miles per hour while driving to a relative's house. On the return trip, you average 50 miles per hour because of bad weather. The total driving time is 5 hours and 15 minutes. How long does each trip take?
Answers
We conclude that the frist trip takes 2.75 hours and the second one 2.5 hours.
How long does each trip take?
Remember the relation:
Distance = Speed*Time.
Here the total distance of the trip is 55mi + 50mi = 105mi
And the total time is 5 hours and 15 minutes, remember that:
60 min = 1 hour
Then; 15 min = 0.25 hours.
So the total time is 5.25 hours, with that we conclude that the average speed is:
S = 105mi/5.25 h = 20 mi/h
The first trip is 55 miles long, then the time in which it is travelled is:
T = (55 mi)/(20 mi/h) = 2.75 hours
The second trip is 50 miles long, then:
T' = (50mi)/(20 mi/h) = 2.5 hours.
We conclude that the frist trip takes 2.75 hours and the second one 2.5 hours.
