What is the center and variability of the dataset?A stemplot is a type of table where figures are divided into a stem and a leaf. The stem is the first number in the digit while the leaf is the last number. For example in the number 31, 3 would be the stem and 1 would be the leaf.
The range is used to measure variation. The range is the difference between the highest number and the smallest number. The largest number is 85 and the smallest number is 43.
The data would be centered around the median. The median is the number at the center of a dataset. The median is a measure of central tendency.
Median = (sum of numbers + 1) / 2
(26 + 1) / 2
= 27 / 2 = 13.5th number
(66 + 67) / 2 = 66.5

[tex]\huge\boxed{112^\circ}[/tex]
To solve this problem, we need to understand the basic rules of transversals across parallel lines.
When a line crosses another line or lines, it is a transversal.
When the two lines it crosses are parallel, the eight angles formed have interesting properties that we can use.
For this question, we will look at corresponding angles. If two angles meet these two conditions, they are congruent:
Both angles are on the same side of the transversal.One angle is interior (between the parallel lines) and the other is exterior.These two conditions are met for [tex]\angle JIK[/tex] and [tex]\angle GFI[/tex], so they are congruent and their measures are equal.
This means that [tex]m\angle JIK=m\angle GFI=\boxed{112^\circ}[/tex]

3 meters of cloth is the ratio of 3:7
Answers
When given 3 meters of cloth to divide in the ratio 3 : 7 then one part of the division will have 0.9 meters and the other side will have 2.1 meters.
How to use ratio to divide?The ratio is 3 : 7 which means that the 3 meters of cloth should be divided such that one part is 3 to the 7 of the other part.
First, find the denominator:
= (3 + 7)
= 10
The smaller part of the cloth:
= 3 / 10 x 3 meters of cloth
= 9 / 10 meters
= 0.9 meters
The larger part of the cloth:
= 7 / 10 x 3 meters of cloth
= 21 / 10

Finally! After nearly two weeks of manual labor in the Georgia summer heat, all of the moving boxes are unpacked and all of your things have a place. You and your three roommates, Alex, Payton, and Jordan, got so lucky in the real estate department. Your apartment is right in the heart of midtown and in walking distance from the Georgia Tech Engineering building where you take the majority of your classes. Everything is perfect! Well… except one crucial component. The four of you cannot seem to agree on an internet and cable provider!
You have narrowed the list of options down to a few of the best companies. All companies offer exactly what the four of you need to continue being top engineering students.The big difference? The price. Your roommates are math enthusiasts and engineering majors just like you, so you know you need to provide extensive evidence to each of them to help move the decision along.
SignoCable has a program where you are able to waive the installation fee and offers your cable for $210 per month.
Urban Cable is offering a special promotion. They are requiring a $320 installation fee upfront. The month to month payment will be $115 for the first 12 months. After the first year, the monthly fee will increase.
ITP Cable requires a lower installation fee than Urban Cable. After six months with this company, you would have paid $1081 since the beginning of the year, and $1257 after 7 months of paying.
MonstroPin Cable company’s installation fee is $100.50. The total payment in August is $59 more than three times the total payment in February.
You’ve decided it’s up to you to save you and your friends money by presenting them with a clear model of the out of pocket expense for all cable companies. Not only do you plan on making a visual representation for Alex, you will even write a proposal that analyses your findings for Payton and Jordan. You will provide them with indisputable evidence of which cable company will provide the most cost effective service. The service you guys choose now will dictate how fast you can register for classes, when you can stream Game of Thrones, and turn your papers in on time.

Which graph represents a linear function?
Answers
Answer:
y + 2x = 10 (third option)
Step-by-step explanation:
We can see that every time x increases by one, y increases by -2, meaning that the slope is -2.
We also know that the y-intercept is 10 because that is the value of y when x is equal to 0.
Now, we can create the equation using the slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept).
y = -2x + 10
If you look at the third option, that equation is just a rearranged form of our equation (y + 2x = 10).
This means that the third option is correct.
Answer:
C, or y+2x=1-
Step-by-step explanation:
Test them one by one. Put the y into the equation and the x in the equation. Whichever ones always work are the correct answer. Remeber, you have to consider all the possible values of x and y when you test them!

Step-by-step explanation:
For example, 2%, read "percent", is two every hundred. When we have 100 liters of water, 2% is 2 liters. If we have 200 liters of water, then 2% is 4 liters. Converting a percentage into a fraction can be done by dividing by 100, following the definition of a percentage.
You wish to purchase a new car, and can afford monthly repayments of up to $150 per month. You see a car you like for $6,000, and are offered financing to secure the purchase. The terms of the deal are that the loan lasts for 5 years, and the annual interest rate is 15.9%. Can you afford to purchase the car on finance?
Answers
The monthly repayment of $145.59 is less than expected monthly payment of $150, hence, the individual can afford tp purchase the car on finance
How do we determine affordability in this case?
In order to determine whether the individual can afford to purchase the car on finance, we need to ascertain the monthly payment of the loan based on the terms of deal provided which would be compared to the expected monthly repayment of $150 using a financial calculator as below:
N=60(number of monthly payments in years=5*12)
I/Y=15.9/12(monthly interest rate without the % sign)
PV=-6000(loan principal)
FV=0(after 60 monthly payments, the balance would be nil)

Answer:

You have a course average of 79% that is 75% of your grade, and you want to know ...
the least final score for a course average of 75%the best possible course average.Weighted averageThe course average is computed as the weighed average of the course grade so far and the final grade. The weighs are 75% and 25%, respectively. In formula form, the relation between the final grade (f) and the course average (c) is ...
0.75(79) + 0.25f = c
Solving for f, we have ...
f = 4(c -59.25) = 4c -237
a) Best course gradeAssuming the best final grade is 100, the best course grade is ...
c = 0.25(100) +59.25 = 25 +59.25 = 84.25
The best course grade is 84.25%.
b) Least final gradeFor a course grade of 75%, the least final grade necessary is ...
f = 4(75) -237 = 300 -237 = 63
The minimum score on the final for a 75% for the course is 63%.
__
Additional comment
Here we have percentages with two different bases. The course grade percentages have a base of the greatest possible number of credits. The weight percentages have a base of the whole course grade. Working with percentages of percentages can be confusing if the base of the percentage is not clear.
We often find it easier to deal with grades expressed as a number 0 to 100, rather than as a percentage. That is what we have done here (except in the final answers). The final answer expresses the course grade as a percentage so as to be consistent with the problem statement.

75 - (60 - 1.03643D)/D = 1.88079
15 + 1.03643D = 1.88079D

The expressions of the range of temperatures would be 2000 - (-120) found in the thermosphere which is the correct answer would be option (D).
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
The fourth layer of the Earth's atmosphere is the thermosphere. It begins just above the mesosphere and rises to a height of 600 kilometres above the Earth's surface.
As you go in height, the temperature in this layer rises. The range of temperatures is from -120°C to 2000°C.
The range of temperatures found in the thermosphere would be the difference between the final temperature and the initial temperature.
initial temperature = -120°C
final temperature = 2000°C
The range of temperatures = final temperature - initial temperature
The range of temperatures = 2000 - (-120)
Therefore, the expressions of the range of temperatures would be 2000 - (-120) found in the thermosphere.

Assuming the pattern continues, what is the formula for the nth term?
an = 48(4n)

an = 4(48n − 1)
an = 48(0.25n − 1)
Answers
Answer:
(d) 48(0.25^(n-1))
Step-by-step explanation:
The points shown on the graph have y-values that decrease by a factor of 4 as x-values increase by 1. The first couple are (1, 48), (2, 12). You want the formula for the n-th term.
Geometric sequenceThe terms of a geometric sequence have a common ratio (r). If the first term is a1, the general term is ...
an = a1(r^(n-1))
ApplicationThe given sequence has first term a1 = 48. The common ratio is ...
r = 12/48 = 1/4 = 0.25
Using these value in the formula for the general term, we find the n-th term to be ...
an = 48(0.25^(n-1)) . . . . n-th term of the pattern
