MAKING AN ARGUMENT Your friend says that the data in the table show a negative correlation because the dependent variable $y$ is decreasing. Is your friend correct? Explain.

yes; Because both variables are decreasing, the data shows a negative correlation.

no; Because both variables are decreasing, the data show a positive correlation


yes; Because at least one variable is decreasing, the data shows a negative correlation.


no; Because the dependent variable is not decreasing at a constant rate, the data show no correlation.

Answer:

Jiri's age = 27

Step-by-step explanation:

Let's use x for Jiri's age.

Jiri's age = x

And because Pamela is 8 years older:

Pamela's age = x + 8

Since their ages added up equal 62, the equation will be:

x + x + 8 = 62

2x + 8 = 62

2x + 8 - 8 = 62 - 8

2x = 54

2x/2 = 54/2

x = 27

And because Jiri's age is x, Jiri's age will therefore be 27.

Hope this helped!

Answer:

Jiri is 27 years old.

Step-by-step explanation:

Step 1: Declare variables

Since Pamela is 8 years older than Jiri. Then, Pamela’s age is [tex]\displaystyle{8+x}[/tex] years old.

Step 2: Form an equation

The sum of their ages together equals to 62. Therefore, we can express in mathematics/equation of [tex]\displaystyle{x+8+x=62}[/tex] (sum of Jiri’s age and Pamela’s).

Step 3: Solve for x-term - add like terms (x-term)

[tex]\displaystyle{2x+8=62}[/tex]

Step 4: Subtract both sides by 8

[tex]\displaystyle{2x+8-8=62-8}\\\\\displaystyle{2x=54}[/tex]

Step 5: Divide both sides by 2

[tex]\displaystyle{\dfrac{2x}{2}=\dfrac{54}{2}}\\\\\displaystyle{x=27}[/tex]

Since Jiri’s age is defined as [tex]x[/tex] years old. Therefore, Jiri’s age is 27 years old.

Here, we need to apply basic mathematical operations and solve the given linear equation. We get the value of a = -4.

Linear equations are expressions that involve variables and constants raised to the power of 1 (i.e., the exponent is 1) and are represented as a straight line when graphed on a coordinate 2D axis. A linear equation can be written in the form ax+ b = c where x is a variable and a,b, and c are constants .

Linear equations can have one variable (univariate) or multiple variables (multivariate). Also, these variables should not be squared, cubed, or raised to the power of any constant other than 1. For example,

1. 2x+5=0 (univariate)

2. 4z+2w=5x(multivariate)

The question given to us is an univariate linear equation where to have to apply basic rules of mathematics. Firstly we need to divide 56 by 14 which gives us 4. The negative sign gives our answer as -4.

Answer:

Slope = (3/5)

Step-by-step explanation:

Point 1: (5, 3); Point 2: (10, 6)

            (x₁, y₁)               (x₂, y₂)

       y₂ - y₁        6 - 3           3

m = ----------- = ----------- = ---------

       x₂ - x₁        10 - 5          5

y - y₁ = m(x - x₁)

y - 3 = (3/5)(x - 5)

y - 3 = (3/5)x - 3

  +3               +3

-----------------------------

y = (3/5)x

Answer:

Slope = (-1/3)

Step-by-step explanation:

Point 1: (-6, 6); Point 2: (6, 2)

            (x₁, y₁)                (x₂, y₂)          

        y₂ - y₁         2 - 6          -4            -4 ÷ 4         -1

m = ------------ = ----------- = ---------- = -------------- = -------

        x₂ - x₁        6 - (-6)      6 + 6        12 ÷ 4           3

y - y₁ = m(x - x₁)

y - 6 = (-1/3)(x + 6)

y - 6 = (-1/3)x - 2

7. [tex]\frac{u}{10}=100[/tex] then multiply both sides by 10: [tex]u=100*10 \\u=1000[/tex]

8. [tex]28+r=128[/tex] subtract 28 from both sides: [tex]r=100[/tex]

Answer:

The point would be (2.5,8.75)

Because we know the customer paid $8.75, we use the y-axis to find this point. Then we'll find where the line meets 8.75 on the y-axis. This is at 2.5. We know that points are in the order of (x,y) therefore the point is (2.5,8.75)

Answer:14

Step-by-step explanation:

abcd = wxyz

ad/dc=wz/yz

12/3=4

56/yz=4

yz=14

Answer:

The Point in the coordinate plane is A(-5,-4)

Perpendicular or shortest Distance from line y=3 that is (-5,3) to point (-5,-4) is

When it is reflected through the line, y=3, the coordinate of point A (-5,-4) changes to (-5,3+7)= B(-5,10).

Now, the Point B is translated by the rule , (x,y)—->(x+6,y),

So,the point B is translated to, (-5+6,10)=(1,10)

(1,10) is the glide reflection of point A(-5,-4).

Answer:The lengths of AB and EF are 10 and 2 respectively

If the triangle ABC and DEF are similar, based on the similarity theorem of a triangle;

AB/DE = BC/EF

5x/4 = 5/x

5x² = 20

x² = 20/5

x² = 4

x = 2

Since the value of x is 2, length of AB is 5x = 5(2) = 10

Since EF = x, hence EF = 2

The lengths of AB and EF are 10 and 2 respectively

Step-by-step explanation:

[tex](3*2)+(6*2)[/tex]

Answer: The ratio is 18:3

Step-by-step explanation:

Answer:  6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18/3

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.

Barry is given 0.4 and 0.9 cents

He already has 6.30 in his bank

0.4+0.9 = 1.3

add the money he was given to the bank

1.3 + 6.3 = $7.60

Barry has $7.60 in total.

Henry buys two candy bars, one is worth 3.20 and the other is 1.60

add them up to get the total

3.20 + 1.60 = 4.80

Henry has $8.50

8.50 - 4.80 = $3.70

Henry has $3.70 left over from the $8.50

Beth buys a bouncy ball worth 1.20 and pen that is 5 times that amount.

this put into an equation is

Answer:

-2/3

Step-by-step explanation:

You are looking the change in y over  the change in x.

for y, if you go from -5 to -7, how much did it change?  -2

-7 -(-5) = -7 + 5 = -2

Now look the the x's.  If you from 6 to 9 how much did you change?

3

9-6 = 3

-2/3

Answer:

-2/3

Step-by-step explanation:

A slope is [tex]\frac{Change in Y}{Change in X}[/tex] and we can see that when the x value increases by 3, the y value decreases by 2. So if we plug that in, we get -2 for the Change in Y and +3 for the Change in X. Which results in the slope being [tex]-\frac{2}{3}[/tex]
