The scatter plot below shows the average number of customers who visit a food truck per day, depending on the number of days the food truck stays in the same location. Which statement best describes the association between the number of days the food truck is in the same location and the number of customers who visit the food truck per day?
A.There is no association.
B.There is a nonlinear association.
C.There is a positive linear association. D.There is a negative linear association.
Answer: There is a positive linear association
Step-by-step explanation:
The best fitted statement is
There is a positive linear association.
What is Linear Association?A straight-line link between two variables is referred to statistically as a linear relationship (or linear association).
If one variable increases roughly at the same rate as the other variables change by one unit, the relationship is said to be linear.
The scatter plot below shows the average number of customers who visit a food truck per day, depending on the number of days the food truck stays in the same location.
As, If the slope is positive, then there is a positive linear relationship, i.e., as one increases, the other increases.
If the slope is negative, then there is a negative linear relationship, i.e., as one increases the other variable decreases.
Here, the slope seems to be positive.
Thus, this is positive linear Association.

Robert sketches two rectangular prisms, A and B. Prism A's side lengths are 5 centimeters, 6 centimeters, and 7 centimeters. Prism B's side lengths were twice those of prism A's: 10 centimeters, 12 centimeters, and 14 centimeters. Robert says the surface area of prism B is twice the surface area of prism A. Is he correct? If he is not, how many times as great as prism A's surface area is prism B's surface area?
Robert is 1.___; the Surface area of A is ____ square centimeters. The Surface area of B is _____square centimeters. B's surface area is ____ times as great as A's.
Answer:
4 times greater
Step-by-step explanation:
Prism A
SA = 2 (lw+wh+lh) where l is length w is width and h is height
SA = 2 ( 5*6+ 6*7+ 5*7)
SA = 2(30+42+35)
SA = 2(107)
SA =214
Prism B
SA = 2 (lw+wh+lh) where l is length w is width and h is height
SA = 2 ( 10*12+ 12*14+ 10*14)
SA = 2(120+168+140)
SA = 2(428)
SA =856
Robert is not correct
856/214 =4
Prism B is 4 times greater
Answer:
Prism B's surface area is 4 times Prism A's.
The surface area of Prism A is 214 square centimeters.
The surface area of Prism B is 856 square centimeters.
Step-by-step explanation:
To find the surface area of a rectangular prism, use this formula:
[tex]A=2(wl+hl+hw)[/tex]
Where w is the width, h is the height, and l is the length.
Substitute the values given for Prism A and Prism B into the formula to find each prism's surface area:
Prism A:
[tex]A=2(5 * 6+6 * 7+5 * 7)\\A = 2 (30 + 42 + 35)\\A = 214[/tex]
Prism B:
[tex]A=2(10*12+12*14+14*10)\\A = 2 (120 + 168 + 140)\\A = 856[/tex]
Prism B's surface area is 4 times Prism A's.
The surface area of Prism A is 214 square centimeters.
The surface area of Prism B is 856 square centimeters.

Hey there! I'm happy to help!
In a 30-60-90 triangle, the shorter leg is always 1/2 of the hypotenuse. This can be proven using many different methods and there a lot of interesting videos out there about it. This is useful in geometry, trigonometry, and more.
So, if we know that the shortest leg is 12, we can make the following equation. We will have h represent the hypotenuse.
1/2h=12
Now, we simply divide both sides by 1/2 (which is the same as multiplying both sides by two.
h=24
Therefore, the hypotenuse is C) 24.

what is the inverse function of f(x)= x/x-2?
Answer:
[tex]f^{-1}(x)=\frac{2x}{x-1}[/tex]
Step-by-step explanation:
Start by replacing f(x) by the variable "y" and solving for x in the equation:
[tex]f(x)=\frac{x}{x-2} \\y=\frac{x}{x-2}\\(x-2)\,y=x\\xy-2y=x\\xy-x=2y\\x(y-1)=2y\\x=\frac{2y}{y-1}[/tex]
Now do the final replacement using the inverse function notation, and replacing "y" with "x":
[tex]x=\frac{2y}{y-1} \\f^{-1}(x)=\frac{2x}{x-1}[/tex]
The inverse of the function f(x)= x/x-2 is; f-¹(x) = 2x/(x-1)
Since the function can be rewritten as;
y = x/x-2By making x the subject of the function;
yx - 2y = x x (y -1) = 2yx = 2y/(y-1)By swapping x and y; we then have;
y = 2x/(x-1)The inverse function is therefore; f-¹(x) = 2x/(x-1)

Equation of a parallel line ?
Equation of a perpendicular line ?
Explain how you know if two lines are parallel or perpendicular based on their equations
Answer:
1) y=1/2x+12
2)y=-2x+13
3) Parallel lines have same slope, different y intercept and perpendicular lines have opposite reciprocal slopes.
Step-by-step explanation:
Answer:
Below in bold.
Step-by-step explanation:
Y = mx + b is the slope-intercept form of a straight line where m = the slope of the line and b is the y-intercept.
Parallel lines have the same slope so the equation of a line parallel to
y = 1/2x + 13 could be y =1/2x + 10 as they have the same slope of 1/2.
Equations which are perpendicular:
If the slope of one is m then the slope of the perpendicular equation is -1/m.
So for y = 1/2 x + 13 an equation perpendicular could be y= -(1 / 1/2) + 13
= y = -2x + 13

As per the given data:
We are given 2 graphs in the diagram.
We are also given the equation of f(x) with its graph.
Furthermore, we have to find out the equation of g(x) from its graph.
We can see that the blue graph is just the red graph with its axis moved 2 units to the right.
We can find the horizontal transformation by:
g(x) = f(x - h)
Where h is the number of units we shift (to the right).
Since we shifted two units to the right, h = 2.
So, our new function will be:
g(x) = (x - 2)²
The correct option is B.

Answer:
<2 and <4 = 74 degrees
Step-by-step explanation:
<7=<1, alt exterior angles
<1=<3, opposite angles
<1+<2= 180
since angle one is 106 just subtract 106 from 180 and you get 74= <2
<2 and <4 are opposite angles so they are congruent
therefore, <2 and <4 = 74 degrees.

Answer:
112°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
16x is an exterior angle of the triangle, thus
16x = 7x - 1 + 8x + 8, that is
16x = 15x + 7 ( subtract 15x from both sides )
x = 7
Thus
16x = 16 × 7 = 112
The exterior angle is 112°
