Jordan looks at the line plot. He says the difference between the most capacity and the least capacity is 1/4 gallon. He says he knows the difference without subtracting. Explain Jordan’s mistake and find actual difference between measurements.
Answers
In a line plot the maximum value is the rightmost mark in the line plot; in this case the maximum capacity is 2 1/2. On the other hand the minimum value is the leftmost mark in the line plot, here the minimum is 1 1/2. Let's calculate the difference between them:
[tex]2\frac{1}{2}-1\frac{1}{2}=1[/tex]Therefore, the difference between the maxiimum and minimum capacity is 1.

What is the equation of the
line that goes through
(-1, 3) and is perpendicular
to y = 4x - 7?
Answers
Answer:
Step-by-step explanation:Perpendicular lines have a slope that is the negative reciprocal of the given line.
For example, if a given line has the slope 3/2, the the perpendicular line would have the slope -2/3.
For the given line: y = 4x - 7, the perpendicular line would have a slope of -1/4
There isn't enough info in the question to determine the y-intercept. Literally, any y-intercept could work and the line would still be perpendicular. Is the line supposed to pass through a certain point?
Your answer would be something like: y = -1/4 x + b
b is the y-intercept...if your question paper is multiple choice, choose the answer with the slope of -1/4. If it's supposed to pass through a certain point (x,y) replace x and y with the values in that point and solve for b to get the y-intercept.

Answers
We have to identify the rational number.
Any number that can be expressed as a fraction is a rational number.
In this case the options are:
A. The square root of 3. This does not have a solution with finite number of decimals, so it can not be expressed as a fraction. Then, it is not rational.
B. The square root of 36, unlike the square root of 3, does have a rational solution: 6. So the square root of 36 is a rational number.
C. The square root of 7. This does not have a solution with finite number of decimals, so it can not be expressed as a fraction. Then, it is not rational.
D. The number π has an infinite number of decimals, so it can not be represented as a fraction. Thn, it is not a rational number.

Given{x=7y-9 2x-14y= -18I think the solution is b? Am I correct?
Answers
there are infintely many solutions. The solution set is {(x, y)| x = 7y - 9} or {(x, y)| 2x - 14y = -18 (option B)
Explanation:Given:
x = 7y - 9 . . .(1)
2x - 14y = -18 . . . (2)
To find:
the solution of the system of equations
To determine the value of x and y, we will apply the substitution method:
we will substitute for x in equation (2):
2(7y - 9) - 14y = -18
2(7y) + 2(-9) - 14y = -18
14y - 18 - 14y = -18
14y - 14y - 18 = -18
0 - 18 = -18
-18 = -18
The left-hand side of the equation is equal to the right side of the equation.
when this happens, it is called infinitely many solutions.
Hence, there are infintely many solutions. The solution set is {(x, y)| x = 7y - 9} or {(x, y)| 2x - 14y = -18 (option B)

The solution to the given inequality in interval notation is: -6 ≤ v ≤ 3
How to solve the given inequality?In this exercise, you're required to determine all the values of v that simultaneously satisfy given inequality. First of all, we would have to eliminate the fraction on the left-hand side of the inequality by adding using an appropriate lowest common denominator of 3 as follows:
(2 × |4v + 6|)/3 - 2/1 ≤ 10
[(2 × |4v + 6|) - (3)2]/3 ≤ 10
[(2 × |4v + 6|) - 6]/3 ≤ 10
Cross-multiplying, we have:
(2 × |4v + 6|) - 6 ≤ 10 × 3
(2 × |4v + 6|) - 6 ≤ 30
Adding 6 to both sides, we have:
(2 × |4v + 6|) - 6 + 6 ≤ 30 + 6
(2 × |4v + 6|) ≤ 36
Dividing both sides by 2, we have:
(2 × |4v + 6|)/2 ≤ 36/2
|4v + 6| ≤ 18
Evaluating the absolute value function, we have:
4v + 6 ≤ ±18
For the positive interval, we have:
4v ≤ 18 - 6
4v ≤ 12
v ≤ 12/4
v ≤ 3.
For the negative interval, we have:
4v ≥ -18 - 6
4v ≥ -24
v ≥ -24/4
v ≥ -6
Lastly, we would express the solution as an interval notation as follows:
-6 ≤ v ≤ 3

The value of f(2) would be 80 which is determined by substituting the value of x = 2in the given function f(x) = (x −2)(2x³ + 10x² + 16x + 34) + 80.
What is a function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
The given function below is:
f(x) = 2x⁴ + 6x³ −4x² +2x + 12
f(x) = (x −2)(2x³ + 10x² + 16x + 34) + 80
We have to determine the value of f(2).
⇒ f(x) = (x −2)(2x³ + 10x² + 16x + 34) + 80
Substitute the value of x = 2 in the given function,
⇒ f(x) = (2 −2)(2(2)³ + 10(2)² + 16(2) + 34) + 80
⇒ f(x) = (0)(2(2)³ + 10(2)² + 16(2) + 34) + 80
⇒ f(x) = 0 + 80

Given that Yasir received a 50% increase in his allowance this year. He now receives £33 a week.
The weekly allowance for last year will be calculated as,
1.5 x (X) = £33
