Answer:
A) Negative Correlation. B) C. C) B
Step-by-step explanation:
<h2>A:</h2>
As the line of best fit is travelling downwards, it is a negative correlation, if the line of best fit is travelling upwards, it is a positive correlation, if the points on the graph are all over the place, there is no correlation.
<h2>B:</h2>
As there are only three types of correlation, the strongest is always the positive.
<h2>C:</h2>
The answer is B because there is no correlation and that means that there shouldn't be a line of best fit.
Answer:
Step-by-step explanation:
We can simply divide both sides of the equation by (1 + rt) and we get the answer.
Answer:
Length = 34 and Width = 30
Step-by-step explanation:
This is a simple system of equation that is mainly solved using substitution, so keep in mind the following key points:
- Rectangle's Perimeter is 128 ft.
- "the garden is 4 feet longer than it is wide," this simply means that the Length is 4 feet longer than the Width: which algebraically translates to
- Perimeter formula for Rectangle is
First, we find the Width by plugging the given values in the formula:
All we did here was substituting 4 + W for L to find the Width.
Now, to find the Length we plug in the value of W and solve for L:
Tip: always sketch a rough geometrical diagram of word problems, it helps. (Refer to the diagram attached)
