By looking at the given graphs, we conclude that the set of data with the strongest linear association is the one in the top right.
What is the linear association?
Linear association is a measure of "how much" a set of data behaves like a line.
So, we just need to see which of the given sets of data behaves more like a line (we can compare with the shown lines).
As you can see, in the only set where almost all the points lie in the graphed line is in the top right graph. In the other 3, we can see points outside of the line.
So the set of data with the strongest linear association is the one in the top right graph.

What does a correlation coefficient mean?
A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another. In positively correlated variables, the value increases or decreases in tandem.
What is a perfect correlation?
A relationship between two variables, x, and y, in which the change in the value of one variable is exactly proportional to the change in the value of the other. That is, knowing the value of one variable exactly predicts the value of the other variable (i.e., rxy = 1.0).

A circle with radius 9 has a sector with a central angle of 120°.
What is the area of the sector?
Answers
120º is 1/3 of a complete revolution of 360º. So the area of this sector should be 1/3 the area of the complete circle.
A circle with radius 9 has area 9^2 π = 81π.
So the sector has area 81π/3.
Put another way: The area A of a circular sector and its central angle θ (in degrees) occur in the same ratio as the area of the entire circle with radius r according to
A / θ º = (π r ^2) / 360º
==> A = π/360 θ r ^2
In this case, r = 9 and θ = 120º, so
A = π/360 * 120 * 81 = 81π/3
A line is drawn through (-7, 11) and (8, –9). The equation
y - 11 = - 4(x + 7) is written to represent the line. Which
equations also represent the line? Check all that apply.
3y = - 4x + 40
4x + y = 21
4x + 3y = 5
-4x + 3y = 17
Answers
The options A and C represent the same line as the given equation.
A: 3y = - 4x + 40
C: 4x + 3y = 5
To verify which equations represent the same line as the given equation y - 11 = -4 (x + 7), we can first convert the given equation into slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.
Given equation:
y - 11 = -4 (x + 7)
Expanding and rearranging:
y - 11 = -4x - 28
y = -4x - 28 + 11
y = -4x - 17
Now, let's compare this equation with the options:
A. 3y = -4x + 40
To convert it to slope-intercept form:
y = [tex]-\frac{4}{3}x + \frac{40}{3}[/tex]
B. 4x + y = 21
To convert it to slope-intercept form:
y = -4x + 21
C. 4x + 3y = 5
To convert it to slope-intercept form:
3y = -4x + 5
y = [tex]-\frac{4}{3}x + \frac{5}{3}[/tex]
D. -4x + 3y = 17
To convert it to slope-intercept form:
3y = 4x + 17
y = [tex]\frac{4}{3}x + \frac{17}{3}[/tex]
Comparing all the equations with the original equation y = -4x - 17, we find that options A and C have the same slope-intercept form as the original equation.
The question is:
A line is drawn through (-7, 11) and (8, –9). The equation y - 11 = - 4(x + 7) is written to represent the line. Which equations also represent the line? Check all that apply.
A. 3y = - 4x + 40
B. 4x + y = 21
C. 4x + 3y = 5
D. -4x + 3y = 17
The only equation that represents the same line as the given equation y - 11 = - 4(x + 7) is -4x + 3y = 17, as it has the same slope and y-intercept when simplified.
To determine which equations also represent the line through the points (-7, 11) and (8, -9), we must ensure they have the same slope and y-intercept as the given line equation y - 11 = - 4(x + 7). First, we simplify the given equation to the slope-intercept form (y = mx + b):
y = -4x - 28 + 11
y = -4x - 17
The slope (m) is -4, and the y-intercept (b) is -17. Now, let's compare the other equations:
3y = - 4x + 40
y = - 4/3x + 40/3Slope: -4/3 (doesn't match)Y-intercept: 40/3 (doesn't match)4x + y = 21
y = -4x + 21Slope: -4 (matches)Y-intercept: 21 (doesn't match)4x + 3y = 5
3y = -4x + 5y = -4/3x + 5/3Slope: -4/3 (doesn't match)Y-intercept: 5/3 (doesn't match)-4x + 3y = 17
3y = 4x + 17y = 4/3x + 17/3Slope: 4/3 (matches)Y-intercept: 17/3 (matches after converting the fraction)The only equation that has both the slope and y-intercept identical to the given line's equation after simplification is -4x + 3y = 17.

Tarzan is swimming east at 2.4 m/s across a river that is 1660 meters wide and
flows north at 5.2 m/s
What is tarzan’s final rate of swimming?
Answers
Tarzan’s final rate of swimming is 4.83 minutes.
What is velocity?Velocity is the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference.
Now it is given that,
Tarzan is swimming east at Velocity, Vt = 2.4 m/s
River's Velocity flowing north, Vr = 5.2 m/s
Width of river = 1660 meters
So, resultant speed of Tarzan, V = √(Vt² + Vr²)
⇒ V = √(2.4² + 5.2²)
⇒ V = √(5.76 + 27.04²)
⇒ V = √32.8 m/s
⇒ V = 5.73 m/s
Thus, rate of swimming = Width / V
⇒ rate of swimming = 1660 / 5.73 s
⇒ rate of swimming = 289.70 s
or, rate of swimming = 4.83 minutes
Thus, Tarzan’s final rate of swimming is 4.83 minutes.

What is mathematical function?A mathematical phrase, rule, or law that establishes the link between an independent variable and a predictor variables (the dependent variable).
In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences. German mathematician Paul Dirichlet initially offered the standard concept of function in 1837. When Nick checked his work it did not match the standard form function.

Nick wrote the function p(x) = 17 + 42x – 7x2 in vertex form. His work is below.
p(x) = –7x2 + 42x + 17
p(x) = –7(x2 – 6x) + 17

When Nick checked his work it did not match the standard form function. Analyze Nick’s work. What was his mistake?
In step 1, he did not put the function in standard form correctly.
In step 2, he should have also factored –7 from the constant term, 17.
In step 3, he did not subtract –7(9) to keep the function equivalent.
In step 4, he did not write the perfect square trinomial correctly as a binomial squared.
Nick made mistakes in converting to standard form, factoring constants correctly, maintaining equivalence, and writing perfect square trinomials. Correcting these steps will yield an accurate transformation of the equation.
Let's break down the steps Nick likely took and identify where he went wrong in putting the quadratic equation into its standard form.
Step 1: Initially converting the equation to standard form. For the equation x² + 4x + 21 = 0, the equation was already in standard form, so no changes were necessary here. It’s possible that Nick incorrectly adjusted coefficients, which led to errors.Step 2: Factoring out terms. If Nick had an equation like -7x² + 17 = 0, he should have factored out -7 from both the x² term and the constant term, resulting in -7(x² - 17/7) = 0. Missing this step would lead to misrepresentation of the equation.Step 3: Ensuring equivalence. Nick should have subtracted -7(9) correctly to maintain the function's equivalence throughout the transformation.Step 4: Writing the perfect square trinomial correctly. To complete the square, for example, (x + 2)² should be correctly represented as a binomial squared. Not doing so indicates an error in the transformation process.In summary, Nick’s mistakes include incorrect standard form conversion, improper factoring of constant terms, failing to maintain equivalence, and incorrect representation of perfect square trinomials.

Answer:
A is 29 miles and B is 18 miles
Step-by-step explanation:
Set up 2 equations involving A and B and solve simultaneously, that is
5A + 2B = 181 → (1)
2A + 3B = 112 → (2)
Multiply (1) by 3 and (2) by - 2 to eliminate B
15A + 6B = 543 → (3)
- 4A - 6B = - 224 → (4)
Add (3) and (4) term by term to eliminate B
(15A - 4A) + (6B - 6B) = 543 - 224, that is
11A = 319 ( divide both sides by 11 )
A = 29
Substitute A = 29 into either of the 2 equations and solve for B
Substituting into (1)
5(29) + 2B = 181
145 + 2B = 181 ( subtract 145 from both sides )
2B = 36 ( divide both sides by 2 )
B = 18
Thus
Route A is 29 miles long and Route B is 18 miles long.

Mikayal spent 3/8 of her savings at the store. She spent $60. How much money was in her savings before she went to the store ?
Answers
Answer:
225
Step-by-step explanation:
60 divided by 3/8 is 225
Final answer:
Mikayla spent 3/8 of her savings which was $60, so by setting up a proportion and solving it, we find that she had $160 in her savings before she went to the store.
Explanation:
Mikayla spent 3/8 of her savings which was $60. To find out how much money she had before going to the store, we can use a simple proportion. We know that the part Mikayla spent ($60) corresponds to 3/8 of her total savings. To find the whole, we set up a proportion:
3/8 = $60/Total Savings
Now, we will solve for the 'Total Savings' by multiplying both sides of the equation by the reciprocal of 3/8, which is 8/3:
Total Savings = $60 × (8/3)
Total Savings = $60 × 8 ÷ 3
Total Savings = $480 ÷ 3
Total Savings = $160
Therefore, Mikayla had $160 in her savings before she went to the store.
