Hello there!
The mean score means the average, or the sum of the scores divided by how many scores there were in total.
Let's find the mean first to get it out of the way.
37 + 73 + 77 + 84 + 85 + 115 = 471.
471 / 6 = 78.5
Your mean is 78.5, or 79 when estimated.
The median is the middle number in a sequence listed from least to greatest. It's actually pretty simple to find. I use a pretty easy method to finding it.
First, set the numbers from least to greatest.
37, 73, 77, 84, 85, 115.
Eliminate the first and last numbers.
73, 77, 84, 85.
Repeat the process.
77, 84.
Since there are no middle numbers left, we must average the two numbers.
Add 77 to 84 and divide by 2.
77 + 84 = 161
161 / 2 = 80.5
Your median is 80.5
Our mean is 78.5 or 79, and our median is 80.5 or 81.
The median actually scores better, as it gives us a closer number to the center of what we're dealing with.
I hope this helps!
The ratios are not equivalent.
ANSWER
EXPLANATION
The equation of a parabola in factored form is
where 'a' is the leading coefficient and 'm' and 'n' are the zeros.
From the question, the zeros of the parabola are 6 and −5.
This implies that,
We plug in these zeros to get:
If (-1, 3) is a point on the graph of this parabola,then it must satisfy its equation.
We substitute x=-1 and y=3 to obtain:
The first choice is correct.
