A + b = 1013;
a - b = 9;
2a = 1022 => a = 511; b = 502;
The statement that correctly compares the students’ test scores is that the median of Jen's score is greater than the median of Ron's score.
<h3>How to find mean and median?</h3>
Jen and Ron each took five tests. There test score are as follow:
- Jen: {45, 91, 84, 66, 74}
- Ron: {70, 95, 99, 69, 72}
Let's find the mean and median of the test score to compare them correctly
Jen: {45, 66, 74, 84, 91}
mean of Jen score = 45 + 66 + 74 + 84 + 91 / 5
mean of Jen score= 360 / 5
mean of Jen score = 72
Median of Jen score = 74
Ron: {69, 70, 72, 95, 99}
mean of Ron score = 69 + 70 + 72 + 95 + 99 / 5
mean of Ron score = 405 / 5
mean of Ron score = 81
median of Ron score = 72
Therefore, the median of Jen's score is greater than the median of Ron's score.

<u>Answer:</u>
The expression that represents "the sum of x and 8" is x + 8
<u>Solution:</u>
Given, a sentence “the sum of x and 8”
Now, we have to write an expression that represents the above given line and check the correct option.
So, now, let us take the given expression and convert it into the polynomial form.
Take, “the sum of x and 8" → sum of x and 8 → x + 8.
Here "+" denotes sum or addition.
Hence, expression for “the sum of x and 8” is x + 8 and option c is correct.
