We start to solve this by looking for the formula that let us calculate an average value, this formula would be:
where Save is the average score and s is the score of each exam, Since we know the value of the score Save and 4 of the exams we can replace them in the formula, like this:
And we can solve for s5, which is the score that we need to find, like this:
Then, Pedro must have a 55 score on the fifth test
Answer:
1. What is the y-intercept? y = 4
2. What is the maximum point? 4
3. What are the x-intercepts? (write the negative one first) x = -2 and x = 2
Step-by-step explanation:
In simple terms, the y-intercept is the part (s) where the graph hits the vertical line.
The maximum point is the highest point of the graph, coincidentally the maximum point on this graph is right on the y-intercept.
In simple terms, the x-intercept is the part (s) where the graph hits the horizontal line.
Answer:
Yes!
Step-by-step explanation:
Because it passes the vertical line test.
0.36 if you round up to the hundredths
