Answer:
You would need to score a 93% to have an average of 90.
Step-by-step explanation:
Well, to check my work you would need to find the average.
So, 93 + 92 + 88 + 87 = 360. Then you divide by four; 360 / 4 = 90. ^^
Hello,
f(x)=2x^3-x^2-4x+9=(((0+2)x-1)x-4)x+9
f(3)=(((0+2)*3-1)*3-4)*3+9=((2*3-1)*3-4)-3+9=(5*3-4)*3+9=11*3+9=33+9=42
or
f(3)=2*3^3-3^2-4*3+9=2*27-9-12+9=54-12=42

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:
