If there is a relationship between dependent and independent variables represented in a scatterplot, The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right.

The independent variable is the one that influences the dependent variable. If there is a relationship between them, it doesn't matter the direction of the points in the scatterplot, but the correlation coefficient.

If the points go up from left to right, the correlation is called direct correlation (increasing the value of the independent variable will increase the value of the dependent variable).

If the points go down from left to right, the correlation is called inverse correlation (increasing the value of the independent variable will decrease the value of the dependent variable)

Have a nice day.

if it takes 10 minutes for 15 machines to make 5 widgets, how many minutes would it take 5 machines to make 15 widgets
pshichka [43]

The number of minutes it will take 5 machines to make 15 widgets is 90 minutes

Given that :

The time taken to make a widget is directly proportional to the number of widgets made and inversely proportional to the number of machines utilized.

Using the variation protocol defined :

Let :

n = number of widgets made

n = number of widgets made m = number of machines used

n = number of widgets made m = number of machines used t = time taken

Hence, from joint variation :

t α n α 1/m

t = kn/m

Where k = constant of proportionality :

Solving for k

When t = 10, n = 5, m = 15

10 = (k × 5) / 15

15 × 10 = 5k

150 = 5k

k = 150 / 5

k = 30

Equation becomes :

t = 30n/m

Solve for t ;

When m = 5 ; n = 15

t = (30 × 15) / 5

5t = 450

t = 450 / 5

t = 90

Hence, it will take 90 minutes.

Allushta [10]

Answer: =3x^2-15x+7

Step-by-step explanation:

\left(5x^2-8x+2\right)-\left(7x+2x^2-5\right)

=5x^2-8x+2-\left(7x+2x^2-5\right)

=5x^2-8x+2-7x-2x^2+5

=3x^2-15x+7
