Ari’s teacher says he may have his report grade based on either the mean or the median of his last six test scores.
viva [34]

The mean would be the best! The mean is when you add up all of those grades and divide by the amount of exams.

If you're solving it,

504 is the total divided by 6 tests would be 84.

2. Which of the following methods can't be used to find the zeros of a function?
ser-zykov [4K]

Answer:

The correct option is;

Substitute x = 0 in the function  and solve for f(x)

Step-by-step explanation:

The zeros of a function are the values of x which produces the value of 0 when substituted in the function

It is the point where the curve or line of the function crosses the x-axis

A. Substituting x = 0 will only give the point where the curve or line of the function crosses the y-axis,

Therefore, substituting x = 0 in the function  can't be used to find the zero's of a function

B. Plotting a graph of the table of values of the function will indicate the zeros of the function or the point where the function crosses the x-axis

C. The zero product property when applied to the factors of the function equated to zero can be used to find the zeros of a function

d, The quadratic formula can be used to find the zeros of a function when the function is written in the form a·x² + b·x + c = 0
