For one year:
0.08(1800) + 1800
But because it is 5 years:
5(0.08(1800)) + 1800
0.4(1800) + 1800
We can make it simpler:
1.4(1800)
Multiply:
2520
YOU NOW HAVE $2520
Answer:
<h3>Part A</h3>
- <em>The graph is attached</em>
<h3>Part B</h3>
For zero number the cost is zero and the rate of change is 25.
- 0 - 0, 1 - 25, 2 - 50, 3 - 75, 4 - 100
This is the indication of the proportional relationship
<h3>Part C</h3>
- It is a constant change as the difference is same for each step - 25
- The ordered pair (1, 25) shows the unit rate is $25 per pair of shoes
<h3>Part D</h3>
- Constant of proportionality is 25
<h3>Part E</h3>
<u>The equation is:</u>
where y - cost, x - number of pairs of shoes, 25 - constant of proportionality
Given:
Scatter plot of weight loss plan.
To find:
how many pounds were lost per month with 4 hours of weekly.
Solution:
Take any two points on the trend line.
Let the points are (3, 4) and (5, 7).
Slope of the line:
m = 1.5
Using point-slope formula:
Add 4 on both sides.
Approximate equation of a line is y = 1.5x - 0.5
Substitute x = 4.
y = 1.5(4) - 0.5
y = 6 - 0.5
y = 5.5
Which is nearly equal to 6.
Also see in the scatter plot, y-value for the corresponding value of 4 in x-axis is 6.
Hence 6 pounds lost per month with 4 hours of weekly aerobic activity.
Answer:
The time spent studying is the response variable.
Step-by-step explanation:
The response variable, also known as the dependent variable is the main question which the experiment wants to provide an answer for. Usually, the predictors determine or affect the response variable. In the study where Teresa investigates the effect of grade level on time spent studying, the response variable is the time spent studying, while the predictor which is the grade level provides an explanation as to the time spent studying.
The changes or variations on time spent studying depends on the grade level. This means that the grade level provides an explanation of the length of time dedicated to studying.
