Step-by-step explanation:
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.

Answer:
heres a example
Step-by-step explanation:
A sports club needs to raise at least $500 by selling chocolate bars for $2.50 each. Sebastian wants to know how many chocolate bars, c, the sports club must sell in order to reach its goal. Which of the following must be true about the inequality and the resulting graph?
they must sell at least 200 choc bars
c=choc bars
2.5c>or=500
divide both sides by 2.5
c>or=200
Answer:
x=2 and y=-1. The steps--
Step-by-step explanation:
<em>FIRST STEP: </em>SUBSTITUTE -4y with the definition in y=2x-5. This makes the first equation -3x-4(2x-5)=-2
<em>SECOND STEP: </em>DISTRIBUTE -4 throughout the parenthesis, making the equation -3x-8x+20=-2.
<em>LAST STEP: </em>SOLVE by combining like terms, -3x-8x, to make -11x, and subtracting 20 from each side, to make -11x=-22. Then divide both sides by -11, making x=2. From there, you solve that y=2(2)-5, solving that y=4-5, y=-1.
Therefore, x=2 and y=-1
