Adam would like to buy a used car, and collected several data to evaluate the best model (such as age, price, weight, etc.) Thanks to a scatterplot, he established that the relation between age and weight is somewhat linear. He calculated that the correlation between age and weight is 0.512. Describe the association.
Answer: There is a strong association between age and weight.
Step-by-step explanation:
The correlation coefficient (r) is used to describe the relationship between two variables.
[tex]-1\leq r\leq1[/tex]
If r lies between -1 to -0.5 or 0.5 to 1, then there is strong association between them.
Here, Variables: Age and weight.
correlation coefficient = 0.512
That means, there is a strong association between age and weight.
Write the equation in slope-intercept form. y=7(x+2)+3x
A. y=10x+14
B. y=−10x+14
C. y=9x+15
D. y=−9x+15
Answer: y = 10x+14 (choice A)
===================================
Work Shown:
y = 7(x+2)+3x
y = 7x+7*2+3x ..... distribute
y = 7x+14+3x
y = (7x+3x)+14
y = 10x+14
This is in y = mx+b form with m = 10 as the slope and b = 14 as the y intercept.
Answer: The answer is A (y=10x+14)

y - 6 + x; use x = 6, and y = -2
Answer:
If you want y-6+x solved, it's -2
Step-by-step explanation:
Substitute 6 for x and -2 for y and you get (-2 - 6 + 6 =?). -2 - 6 = -8. -8 +6 = -2.
Simple way to do this is the given -6 and the 6 cancel out and that leaves the -2 from the y.

Answer:
There is one solution (4,0)
Step-by-step explanation:
First, we will try to solve this system of equations.
I will rearrange 2x-5y=8 to isolate -5y.
The new equation would be 5y=2x-8.
Now we will add
2x -8 = 5y
with
-2x+8=5y
We get 0 = 10y
Divide by 10 and we get y = 0.
Now that we know the value of y, lets solve for x.
2x-8=5(0)
2x-8=0
Add 8
2x=8
Divide by 2 to isolate x
x = 4.
x=4 and y=0
The solution is (4, 0)

Step-by-step explanation:

[tex]a.\: \frac{1}{12}[/tex]
Step-by-step explanation:
The probability he will roll an odd number on the first roll is [tex]\frac{1}{2}[/tex] as there are three odd numbers and three even numbers on a fair six-sided dice.
The probability he will roll the number 4 on the second roll is [tex]\frac{1}{6}[/tex] as out of the six numbers, only one is the number 4.
Therefore the probability of both happening is [tex]\frac{1}{2}\cdot \frac{1}{6}=\fbox{$a.\: \frac{1}{12}$}[/tex].

BC = 200/7 ≈ 28.57
Step-by-step explanation:
Set up a proportion to solve for the missing side length.

The supply and demand for vintage vinyl records are shown. Where is the equilibrium point.
Answer:
The point where the demand curve and the supply curve meets
Step-by-step explanation:
The equilibrium point is the point at which the quantity of vintage vinyl supplied and the quantity demanded is equal at a particular price.
From the graph, the equilibrium point is the point at which the demand curve and the supply curve intersects.
So, the equilibrium point if vintage vinyl is at the point somewhere between the price of 20 and 30, and the point where the quantity is somewhere between 50 and 100.

Anna is selling boxes of cookies and tubs of popcorn for a Student Council fundraiser. On Monday, she made $40 selling 4 boxes of cookies and 2 tubs of popcorn. On Tuesday, she made $35 selling 1 box of cookies and 3 tubs of popcorn.
Write a system of equations to represent the cost of a box of cookies, x, and the cost of a tub of popcorn, y.
Answer:
5 boxes of cookies and 5 tubs of popcorn = $75
Step-by-step explanation:
To find y divide what is sold by 4 boxes of cookies and x by 2 tubs of popcorn.
The solution is
The cost of box of cookies x = $ 5
The cost of tub of popcorn y = $ 10
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the cost of cookies be = x
Let the cost of popcorn be = y
And ,
On Monday, Anna made $40 selling 4 boxes of cookies and 2 tubs of popcorn
Substituting the values in the equation , we get
4x + 2y = 40 be equation (1)
And ,
On Tuesday, Anna made $35 selling 1 box of cookies and 3 tubs of popcorn
Substituting the values in the equation , we get
x + 3y = 35 be equation (2)
On simplifying both equations , we get
Multiply equation (2) by 4 , we get
4x + 12y = 140 be equation (3)
Subtracting equation (1) from equation (3) , we get
10y = 140 - 40
10y = 100
Divide by 10 on both sides of the equation , we get
y = $ 10
So , the cost of tub of popcorn is $ 10
Substituting the value of y in equation (2) , we get
x + 3y = 35
x + 30 = 35
Subtracting 30 on both sides of the equation , we get
x = $ 5
So , the cost of box of cookies is $ 5
Hence , the cost of cookies is $ 5 and cost of popcorn is $ 10
