Describe some data that when graphed would represent a proportional relationship. Explain your reasoning
Answers
Hope this helps!! :)
Answer:
A proportional relationship is "two quantities vary directly with each other."
Example:
The amount of gasoline you fill in your car and the amount you pay is a proportional relationship.
If 1 gallon of gasoline is $3, then the cost of 3 gallons of gasoline is $9.
Step-by-step explanation:
A relationship is between two quantities.
A proportional relationship is "two quantities vary directly with each other."
Say, if the quantity "x" increases, then the associated quantity "y" also increases.
For example,
y = 2x
Let's find the data.
x y
0 0
1 2
2 4
3 6
As you can see when the value of "x" increases, the value of "y" also increases.
This is called proportional relationship.
Example:
The amount of gasoline you fill in your car and the amount you pay is a proportional relationship.
If 1 gallon of gasoline is $3, then the cost of 3 gallons of gasoline is $9.

L1 and L2 are parallel lines
the equation of L1 is y= 3x + 2
L2 passes through the point (3,4)
find an equation for L2
Answers
y = mx + b
slope(m) = 3
(3,4)...x = 3 and y = 4
now we sub and find b, the y int
4 = 3(3) + b
4 = 9 + b
4 - 9 = b
-5 = b
so ur other line, L2 is : y = 3x - 5 <==
To find the y intercept you have to replace the y and x with the 2 points given and the m with the slope and simplify.
so, y=mx+b
(4)=(3)(4)+b
4=12 +b
8=b
then plug in the intercept and the slope into the slope intercept equation and there is your answer.

Factor expression 42x+49
Answers
Final answer:
To factor the expression 42x+49, we find the GCF which is 7, and express the expression as 7(6x + 7).
Explanation:
The question focuses on the task to factor the expression 42x+49. Factoring is a mathematical process in which we express a number or an algebraic expression as the product of its factors, which are usually simpler or more basic expressions.
To factor the given expression, we look for the greatest common factor (GCF) that both terms share. In this case, the GCF of 42x and 49 is 7. We factor the 7 out:
42x + 49 = 7(6x + 7)
The factored form is 7(6x + 7), which is the simplest form of the expression where 7 is a common factor multiplied by the binomial 6x+7.

Answers
now to split these minutes equally, we will divide them by 7 days of week
daily usage = 190/7 = 27.14 minutes
since we can not talk for 0.14 minutes, therefore,to equally split the remaining minutes, you should speak 27 minutes per day with one extra minutes remaining to be used on the day you choose

Each day, Jake donates money to the global hunger initiative according to how many lunch specials he sells. What is the constant of proportionality in money per lunch special?
Answers
Answer: 1/5
Explanation: Since, according to the given figure,
Jake spends money for 60 lunch special= 12 unit
Therefore, In this case, money per lunch= 12/60=1/5
Jake spends money for 45 lunch special=9 unit
Therefore, In this case, money per lunch= 9/45=1/5
Jake spends money for 30 lunch special=6 unit
Therefore, In this case, money per lunch= 9/45=1/5
Again, Jake spends money for 15 lunch special=3 unit
Therefore, In this case, money per lunch= 3/15=1/5
Thus, from the above explanation it is clear that the money per lunch is same for every condition and is equal to 1/5.
A class is playing a game called “Guess my Number,” in which the number is an integer. The teacher gives these clues for the unknown number. 4 + h ≤ 7 and h + 1 > 3 What is the value of the unknown number, h?
Answers
If you subtract for 4 from 7 in the first expression, then h is less than or equal to 3.
If you subtract 1 from 3 in the second expression then h is greater than 2.
Thus the only value of h possible is 3.
Answer:
the answer is 3
if you subtract for 4 from 7 in the first expression, then h is less than or equal to 3.
If you subtract 1 from 3 in the second expression then h is greater than 2.

The school’s guidance department compares the grade-point averages and standardized state test scores for 10 students in each grade. The table below shows the correlation coefficient for each data set.
Answers
[tex]r^{2}[/tex]
9th grade 0.3 = [tex]0.3^{2}[/tex] = 0.09
10th grade –0.1 = [tex]-0.1^{2}[/tex] = 0.01
11th grade 0.2 = [tex]0.2^{2}[/tex] = 0.04
12th grade –0.8 = [tex]-0.8^{2}[/tex] = 0.64
So 12th grade data set is reasonable but the others are not because they are not remotely close to 1.
The 12th-grade data set represents the linear regression because the value of the correlation coefficient for the 12th-grade students is near the -1 which shows a perfect negative linear regression
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
The correlaton coeffiecient is given as below:
For 9th grade = 0.3
For 10th grade = -0.1
For 11th grade = 0.2
For 12th grade = -0.8
We know that for perfect linear regression the value of the correlation coefficient is 1 or -1
As we can see from the data given the nearest value of the correlation coefficient is -0.8 which is the correlation coefficient for the 12th grade.
Thus, the 12th-grade data set represents the linear regression because the value of the correlation coefficient for the 12th-grade students is near the -1 which shows a perfect negative linear regression.

find the measure of an angle whose supplement measures seventeen times its measure
Answers
lets x = angle
its supplement = 180 - x
x + 17x = 180
18x = 180
x = 10
180 -10 = 170
answer
angle = 10
its supplement = 170
Final answer:
The measure of an angle whose supplement is seventeen times larger than the angle itself is 10 degrees.
Explanation:
We are looking to find the measure of an angle that is said to have its supplement measure seventeen times larger than the angle itself. In terms of mathematical relationships, this means that if we call the angle in question x, then its supplement would be 17x. We know that supplementary angles add up to 180 degrees, hence we can write the equation x + 17x = 180. By solving this equation, we find that 18x = 180, and therefore x = 180÷18 which simplifies to x = 10. So the measure of the angle we are looking for is 10 degrees.

One eighth of a number is less than or equal to 3 what is the inequality
Answers
one eighth of the number = 1/8 x n = n/8
we know that this result n/8) is less than or equal (<=) 3
therefore, the inequality is:
n/8 <= 3
The inequality that represents the scenario given, where one eighth of a number is less than or equal to 3, is X ≤ 24.
Explanation:The problem given can be represented by an inequality. We are told that one eighth of a number is less than or equal to 3. We can express this in equation form as X/8≤3, where X is the unknown number we are trying to figure out.
To solve for X, we can perform the inverse operation of division on both sides of the inequality by multiplying by 8, following the principle of maintaining balance within an inequality. The inequality thus simplifies to X ≤ 24.
