Answer:
The function is .
The slope is .
The y-intercept is .
Step-by-step explanation:
Our aim is to calculate the values <em>m</em> (slope) and <em>b</em> (y-intercept) in the equation of a line :
We have the following data:
To find the line of best fit for the points given, you must:
Step 1: Find and as it was done in the table below.
Step 2: Find the sum of every column:
Step 3: Use the following equations to find <em>b</em> and <em>m</em>:
Step 4: Assemble the equation of a line
The graph of the regression line is:
G(x) can be obtained from F(x) by shifting F(x) 4 units to the right and 1 unit upwards.
Shift towards right can be obtained by subtracting 4 from the x in the function and the upward shift can be obtained by adding 1 to the function.
So,
G(x) = F(x-4) + 1
Thus,
G(x) = (x-4)² + 1
So, the correct answer to this question is option B
Answer:
negative number
Step-by-step explanation:
negative numbers are the opposite of real numbers . for example
-5 -4 -3 -2 -1 0 1 2 3 4 5
Answer:
30/40, 75/100, 9/12, 15/20, 24/32
Step-by-step explanation:
all you have to do is multiply the numerator and the denominator by the same number. for example, 3*5 = 15 and 4*5 = 20 so you get 15/20.
Given the equation: f(p) = 1000p
Since: p = number of days = 150
Then f(p) would be the amount that the house was sold for after being on the market for "p" days. Applying that p = 150; then f(150) means that the house was sold for $150,000 after being on the market for an average of 150 days.
So the answer is 150
