The first step is to calculate the total score needed after the fourth test to determine how much she needs to achieve on her next test.

Given that Mean = (Sum of Scores)/number of tests

we can apply that formula to find the necessary total score.

82 = (Sum of Scores)/4

Thus, 82 × 4 = 328

Therefore, she should have a total score of 328 after four tests

The score required on the fourth test = Total Score Needed - (sum of scores from the first three tests)

= 328 - (72 + 97 + 82) = 77

Thus, she requires a score of 77 on the next test to achieve a mean of 82 and qualify for the team

Which polynomial function could be represented by the graph below?
AnnZ [12381]
According to the graph, which depicts a parabola, we can determine that the function will be quadratic. First, we identify the zeros as x=2 and x=4. Next, we can form the function using a point to solve for 'a'. For instance, at x=3 and y=-3, we can find 'a.' Plugging back into the equation, we can perform necessary multiplications to reach the final function.
