Answer:
The numerical value of the correlation between number of classes skipped and grade index is 0.60.
Step-by-step explanation:
In statistics R² is a measure that is used to determine the proportion of variation in the dependent variable that can be explained by the independent variable. The value of R² is compute by squaring the correlation coefficient (<em>r</em>) between the dependent and independent variable.
In this case the dependent variable is the grades and the independent variable is the number of classes skipped.
The R² between the grades and the number of classes skipped is 36% or 0.36.
Compute the value of <em>r</em> as follows:
Thus, the correlation between number of classes skipped and grade index is ±0.60.
Answer:
Region B & C
Step-by-step explanation:
Usually, in inequality graphs, the solutions are usually located in the shaded region of the graph.
Also, we make the boundary line thick if the points on that line also contain solutions to the inequality.
In this question, the boundary line of function g(x) is thick and the shaded region is B and C.

Answer:
x = 0
Step-by-step explanation:
Step 1: Write equation
4x - 5 - 2x = x - 5
Step 2: Solve for <em>x</em>
- Combine like terms: 2x - 5 = x - 5
- Subtract x on both sides: x - 5 = -5
- Add 5 to both sides: x = 0
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
4(0) - 5 - 2(0) = 0 - 5
0 - 5 - 0 = -5
-5 = -5
First, we can convert feet to inches 1 foot=12 inches 7 feet=84 inches Next, we find out inches per hour 84 inches/27 1/2 hours ----------- -------------- 27 1/2 27 1/2 =3.054 inches/hour
