A. Bike riding makes people want to vacation at home
B. Vacationing makes people want to rife their bikes
C. The correlation is due to a third variable: cost of milk

A study of several cities shows a positive correlation between the percent of people biking to work and the percent of people spending their vacation time at home.
Which statement is most likely true?
A. Bike riding makes people want to vacation at home
Have a wonderful day if you need any other questions from this test let me know!!!!!!!
Final answer:
The correct answer for the correlation coefficient of -0.32 is B. There is a weak negative association.
For the correlation between biking and vacationing at home, the likely third variable is cost of gas, choice D: The correlation is due to a third variable: cost of gas
Explanation:
The correlation coefficient measures the strength and direction of the relationship between two variables. In this case, the correlation coefficient is -0.32, which indicates a weak negative association between the variables. A negative correlation means that as one variable increases, the other variable tends to decrease. So, option B - There is a weak negative association between the variables - is true.
For the second question, based on the information given, it is most likely that option D - The correlation is due to a third variable: cost of gas - is true. This means that the positive correlation between the percent of people biking to work and the percent of people spending their vacation time at home is likely influenced by the cost of gas as a third variable.

Evaluate the function rule for the given value.
y = 15 • 3x for x = –3
Is the answer -135?
Answer: Yes
Step-by-step explanation:
Hi, to answer this question we have to substitute x =-3 on the function given, and solve for the variable y.
y = 15 • 3x
Replacing the value of the variable x by -3:
y = 15 • 3(-3)
Multiplying
y = 15 .-9
y = -135
It is correct, the answer is y= -135

A. x+y=70
y=2x-425
B. x-y=425
y=2x-70
C.x+y=425
y=2x-70
D. x+y=425
y=2x+70
Answer:
Option C is correct
[tex]x+y = 425[/tex]
[tex]y = 2x-70[/tex]
Step-by-step explanation:
Here, x represents Kathryn's score and y represents Michael's score.
As per the statement:
Michael and Kathryn bowl together and their combined total score for one game was 425 points.
⇒[tex]x+y = 425[/tex]
It is also given that Michael's score was 70 less than twice Kathryn's.
⇒[tex]y = 2x-70[/tex]
Therefore, the system of equations models the problem is:
[tex]x+y = 425[/tex]
[tex]y = 2x-70[/tex]

Which of the following statements are true of a transversal?
It is a line.
It is parallel to other coplanar lines.
It intersects two or more coplanar lines.
It bisects line segments.
It can be perpendicular to other lines.
Definition: A transversal is a line that crosses at least two other lines.
Main properties:
It is a line (A is true).It is not parallel to other coplanar lines, because it crosses them (B is false).It intersects two or more coplanar lines (C is true).It bisects line segments (D is false).It can be perpendicular to other lines, it can be perpendicular to lines which it crosses (E is true).Answer: true are options A, C and E.
A transversal in Mathematics is a line that intersects two or more lines at different points, but does not necessarily have to be parallel or bisect these lines. It can, however, be perpendicular to them.
Explanation:In the subject of Mathematics, a transversal refers to a line that intersects two or more coplanar lines at different points. Therefore, the statement 'It is a line' and 'It intersects two or more coplanar lines' are true for a transversal.
The term transversal doesn't necessitate that it be parallel to other coplanar lines, nor does it indicate that it bisects line segments, so these statements are false. However, a transversal can be perpendicular to other lines if it intersects them at 90-degree angles.

You are buying potato chips at the grocery store. You have a manufacturers coupon for a $1.00 off and the store is offering 20% off if you buy 2 bags. You decide to buy 2 bags of potato chips. How do you compute your final cost?
A. Subtract $1.00 off each bag and then multiply by .20
B. Multiply each bag by .20, subtract $1.00 off of each bag, and then add them together.
C. Add the two bags together, multiply by .80, and then subtract $1.00.
D. Subtract $1.00 from the first bag, then add them together, and then multiply by .80.
Answer:
The correct option is: C. Add the two bags together, multiply by .80, and then subtract $1.00.
Step-by-step explanation:
First you need to add the prices of two bags for getting the total sales price.
Now, the store is offering 20% off, that means you need to pay 80% of the total sales price. For finding the amount, we need to multiply the total sales price by 0.80
Then, you have a manufacturers coupon for a $1.00 off. So, for fining the final price, you need to subtract that $1.00 from the last result.
Thus, the correct option will be......
C. Add the two bags together, multiply by .80, and then subtract $1.00.
What is the measure of ∠XYZ
The measure of angle ∠XYZ is 66°.
Given:
∠W + ∠X = ∠XYZ (Sum of opposite interior angles is equal to the exterior angle)
Let's solve for x:
2x + 12 + 2x + 14 = 5x + 16
4x + 26 = 5x + 16
26 - 16 = 5x - 4x
10 = x
Now substitute the value of x into the equation for ∠XYZ:
∠XYZ = 5x + 16
∠XYZ = 5 * 10 + 16
∠XYZ = 50 + 16
∠XYZ = 66°
Therefore, the measure of ∠XYZ is 66°.

What is the axis of symmetry of the function f(x) =-(x+9)(x-21)
Answer:
x = 6
Step-by-step explanation:
The given equation is [tex]f(x)=-(x+9)(x-21)[/tex]
We write the equation in standard form of parabola [tex]f(x)=ax^2+bx+c[/tex] using FOIL
[tex]f(x)=-(x+9)(x-21)\\\\f(x)=-(x^2-21x+9x-189)\\\\f(x)=-x^2+12x+189[/tex]
Now, we know that the axis of symmetry passes through the vertex. Hence, in order to find the vertex of the parabola, we find the x coordinate of the vertex.
x coordinate of the vertex is [tex]-\frac{b}{2a}[/tex]
Here, a = -1 b = 12
[tex]-\frac{b}{2a}\\\\=-\frac{12}{2\cdot(-1)}\\\\=-(-6)\\\\=6[/tex]
Therefore, the axis of symmetry is x = 6

Angle θ lies in the second quadrant, and sin θ = 3/5
Answer:
sin θ [tex]=\frac{3}{5}[/tex]
It is given that , Angle θ lies in the second quadrant.
In the right triangle, Perpendicular =3 units, and Hypotenuse = 5 Units
As, sinθ is positive in second Quadrant also.That is , sin(π-θ )=sin θ
Also, [tex]sin(\frac{\pi}{2}-\Theta)=cos\Theta[/tex]
[tex]sin (\Theta) = 3/5\\\\ (\Theta) =sin^{-1} \frac{3}{5} {\text{or}} (\Theta) =\pi -sin^{-1} \frac{3}{5}\\\\cos(\frac{\pi}{2}-\Theta)= \frac{3}{5}\\\\ \frac{\pi}{2}-\Theta=cos^{-1}[\frac{3}{5}]\\\\ \Theta= \frac{\pi}{2}-cos^{-1}[\frac{3}{5}][/tex]
So, [tex]\pi-\Theta= \frac{\pi}{2}+cos^{-1}\frac{3}{5}, {\text{or}}\pi -sin^{-1} \frac{3}{5}[/tex]
are values of theta which lies in second quadrant.

You invest $5,000 in a savings account that earns 6% interest each year.
A. How much money do you have in your savings account after the first year?
B. How much money do you have in your savings account after the second year?
After the first year, with an initial investment of $5,000 and an annual interest rate of 6%, the total amount in the savings account is $5,300. After the second year, the total amount in the account increases to $5,618.
Explanation:You are investing $5,000 in a savings account with an annual interest rate of 6%. The amount of interest you earn each year is calculated using the formula: principal amount *(interest rate/100).
A. After the first year, you would have:
Interest = $5,000 * (6/100) = $300
Therefore, the total amount in the savings account after one year is $5,000 + $300 = $5,300.
B. For the second year, we apply the same formula to the updated balance from the first year:
Interest = $5,300 * (6/100) = $318
Therefore, the total amount in the savings account after two years is $5,300 + $318 = $5,618.
