Answer:

C) -0.89 is correlation coefficient.

Step-by-step explanation:

Given: data on graph.

TO find : what is the correlation coefficient of the linear fit of the data shown below, to the nearest hundredth.

Solution : We have given a graph

We can see from the graph in which values on x axis is increase and values on  y axis decreases , as we can say correlation coefficient  is negative but not perfect negative .

Therefore, C) -0.89 is correlation coefficient.

<u>Algebra I</u>

Equality Properties

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

[Standard Form]   -5x - 4y = -12

<u>Step 2: Rewrite</u>

  1. Add 5x to both sides:                    -4y = 5x - 12
  2. Divide -4 on both sides:                y = -5/4x + 3

<u>Step 3: Identify</u>

<em>Break apart the function.</em>

Slope <em>m</em> = -5/4

y-intercept <em>b</em> = 3

The figure below is made up of two rectangles.
Dmitry [639]

Answer:

Total area of figure = [3x² + 7x + 6] feet²

Step-by-step explanation:

By dividing both rectangle by vertical line;

Given:

Length of big rectangle = (x + 3) feet

Width of big rectangle = (x + 2) feet

Length of small rectangle = 2x feet

Width of small rectangle = (x + 1) feet

Find:

Total area of figure

Computation:

Area of rectangle = Length x width

Total area of figure = Area of big rectangle + Area of small rectangle

Total area of figure = [(x + 3)(x + 2)] + [(2x)(x + 1)]

Total area of figure = [x²+ 2x + 3x + 6] + [2x² + 2x]

Total area of figure = [3x² + 7x + 6] feet²
