Let's consider that Susan's graph represents a linear equation. We can then perform linear interpolation. Let y denote the charge for 10 hours of work:
(7-10)/(7-11) = (168-y)/(168-264)
y = $240
For Jim’s Lawn care, calculate the consistent slope utilizing the points (1,20) and (2,40):
m = (20 - 40)/(1-2) = 20
Since the y-intercept is zero, the resulting linear equation is:
y = 20x
Substituting x = 10 hours yields,[
y = 20(10) = $200
The variance between the two amounts then becomes:
Difference = $240 - $200 = $40
For a defined population, does a parameter ever change?
Response: For a fixed population, a parameter remains constant.
This is because when determining the parameter, every unit within the population is considered. Thus, a parameter will not differ.
In the case of taking three samples of the same size from a specific population, can we end up with three different values for the same statistic?
Response: Sample data can differ between samples, therefore corresponding sample statistics can also show variation among samples.
As we calculate sample statistics, we focus only on portions of the population. Each sampling from the population carries the potential for differing data. Consequently, statistics derived from samples may vary from one sample to another.
Answer:
700/1=700
This ratio indicates it is 700 times greater, hence we multiply by 700
700 x 0.72 = 504
504 pounds

Step-by-step explanation:
Answer:
A. True
Step-by-step explanation:
The Triangle Inequality Theorem establishes that the sum of two sides must exceed the length of the third side. Let’s verify this.
a + b
9 + 1 = 10>9
a + c
9 + 9 = 18>1
c + b
9 + 1 = 10>9
11,000 multiplied by 16% equals $1,750, which when multiplied by 4 gives a total of $7,040.
Therefore, after 4 years, the car's value is $11,000 - 7,040 = $3,960.
