When two variables move together, they are said to be negatively correlated?.

Step-by-step explanation:

Let's set up an algebraic equation to reflect the ratio of milk to water. We know that for every 1/3 cup of milk, we have 1/4 cup of water, so we can take:

1/3*m=1/4*w

How might we make that 1/3 cup into 1 cup of milk? We multiply by 3! What we do to one side we have to do to the other otherwise we change the equation (and break math), so we will multiply both sides by 3.

(1*3)/3*m=(1*3)/4*w

3/3*m=3/4*w

m=3/4w

Answer:

2,700

Step-by-step explanation:

A=2(wl+hl+hw)=2·(20·30+15·30+15·20)=2700

The values of the variables will be a=3 b=4 and c=81

It is given that

[tex]\dfrac{3^{8} }{3^{4} } = a^{b}=c[/tex]

now we can write that

[tex]3^{8}\times3^{4} =a^{b}[/tex]

[tex]3^{8-4} = a^{b}[/tex]

[tex]3^{4}=81 = a^{b} =c[/tex]

So from the above expression, we can see that a=3 b=4 and c=81

Thus values of the variables will be a=3 b=4 and c=81

Answer:

[tex]y=13x-35[/tex]

Step-by-step explanation:

Use the point-gradient form of a linear equation:  [tex]y-y_1=m(x-x_1)[/tex]

(where [tex]m[/tex] is the gradient and [tex](x_1,y_1)[/tex] is a point on the line)

Given:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-4=13(x-3)[/tex]

[tex]\implies y-4=13x-39[/tex]

[tex]\implies y=13x-35[/tex]

Answer:

[tex]y=13x-35[/tex]

Step-by-step explanation:

[tex]m=13[/tex]

[tex](x_{1},y_{1})=(3,4)[/tex]

[tex]y-y1=m(x-x1)[/tex]

[tex]y-4=13(x-3)[/tex]

[tex]y-4=13x-39[/tex]

[tex]y=13x-35[/tex]

Answer:

x = 3.75

Step-by-step explanation:

Replace y with the y equation.

So..

4x - 2(x + 1.75) = 4

Answer:

(3.75, 5.5)

Step-by-step explanation:

Adding x (3.75) to 1.75 gives 5.50 (5.5). If this is correct, then 4 x 3.75 + 2 x 5.5 = 4

The system of equations represents the situation is x + y = 24 and 1.25x + 0.75y = 25  

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represents the number of spinners and y represents the number of cubes.

There are 24 students in the class and the teacher spent a total of $25, hence:

x + y = 24  (1)

and;

1.25x + 0.75y = 25   (2)

The system of equations represents the situation is x + y = 24 and 1.25x + 0.75y = 25

The solution to the differential equation is:

[tex]g(x) = x^2*sgn(x)[/tex]

We want to solve:

g'(x) = 2*|x|

If we integrate g(x), we will get:

[tex]\int\limits {2*|x|} \, dx[/tex]

Remember that:

Then:

[tex]g(x) = \int\limits {2*|x|} \, dx = 2*(\frac{x^2}{2}*sgn(x)) + C[/tex]

Where sgn(x) is the sign of the value x, and C is a constant of integration.

We also know that g(0) = 0, then:

[tex]g(0) = 2*(\frac{0^2}{2}*sgn(0)) + C = C = 0[/tex]

So we conclude that C = 0.

Then the function is:

[tex]g(x) = x^2*sgn(x)[/tex]

Just by looking at the data, you can see the higher temps in Barstow are more consistent than that of those in Kingman.

If the equal is 55x + 35y = 200

If the car spends 3 hours at 55 miles per hour, then it drove:

  55(3) + 35y = 200

     35y =35

        y = 1.

There the drive spent 1-hour driving at 35 mph.

Answer:

1. x=22  2. x= 28

Step-by-step explanation:

1. The total of angles in a triangle add up to 180˚.

93+65= 158

180-158=22

This means that x = 22

2. Angles on a straight line add up to 180.

180-125=55

180-83=97

55+97=152

180-152=28

This means that x = 28
