Solve the equation 13-2x=-7
patriot [66]
Subtract 13 from both sides.

-13
-7 = -20

-2x = -20

Divide by 2 on both sides.
Remember: Negative divided by a negative makes a positive.

-2/-2 = 1
-20/-2 = 10

Your answer:
x = 10

A student is assessing the correlation between the number of workers in a factory and the number of units produced daily. The ta
lukranit [14]

The number of units produced increases from 2 to 452 as the number of factory workers increases from 0 to 90, which gives;

Part A:

  • Yes there is a strong positive correlation

Part B:

  • The function is <em>y</em> = 5•x + 2

Part C:

  • The slope indicates the number of units produced by each worker daily

  • The y-intercept indicates that two units can be produced without workers.

<h3>How can the existence of a correlation and the best fit function for the data be found?</h3>

Part A:

The correlation is the relationship between variables based on statistical data.

From the given table, the difference between consecutive terms of the <em>x </em>and y-values are constant, therefore as the x-values increases, the corresponding y-value increases.

Change in x-values, ∆x = 10 - 0 = 20 - 10 = 30 - 20 = 10

Change in y-values, ∆y = 52 - 2 = 102 - 52 = 152 - 102 = 50

Therefore;

  • There is a strong positive correlation between the number of workers, <em>x</em>, and the number of units produced, <em>y</em>.

Part B:

Given that the rate of change of the x-values is constant, and the rate of change of the y-values is a constant, the function relating the <em>x </em>and y-values is a linear function, which can be found as follows;

Slope of the equation, <em>m </em>= ∆y/∆x

Which gives;

m = 50/10 = 5

y - 2 = 5•(x - 0)

The function that best fits the data is therefore;

  • y = 5•x + 2

Part C:

The slope of the function is the coefficient of the variable <em>x </em>in the equation, <em>y </em>= m•x + c

  • The slope of the plot, 5, indicates that each worker produces 5 units daily

The y-intercept of the function is the value of the constant term, c, in the equation, y = m•x + c

  • The y-intercept of the linear equation, y = 5•x + 2, which is 2, indicates that the initial number of units of products at the factory before workers arrive is 2.
