The upper quartile for NFC is 3 points higher than that of AFC.
<h3>What is the difference in the upper quartiles?</h3>
A box plot is used to study the distribution and level of a set of scores. The scores are distributed into 4 groups. Each group has a value of 25%
On the box, the third line on the box represents the upper quartile. 75% of the scores represents the upper quartile.
Upper quartile for AFC : 26
Upper quartile for NFC : 23
Difference = 26 - 23 = 3

A cheap way to go about it is, use the LCD and multiply both sides by it.
now, notice the denominators, x, 4, 4x, clearly the LCD is 4x, so let's multiply both sides by that, to do away with the denominators,
Hi , if we want to find the M.A.D of the numbers shown , then we have to add them .
275+252+248+240+240+225+215+214+189+184=2,282
Then we have to divide the number by the total of numbers that we have.
2,282 ÷ 10 =228.2
Then we have to subtract 228.2 by each number that we have.
228.2-275=-46.8
228.2 - 252=-23.8
228.2 - 248=-19.8
228.2 - 240=-11.8
228.2-240=-11.8
228.2-225=3.2
228.2-215=13.2
228.2-214=14.2
228.2-189=39.2
228.2-184=44.2
Then we add those numbers , that gives us 0 , if you don't work with negatives numbers then your answer would be 228 , finally we divide that number by the total of numbers that we have , your answer is 22.8 , if you do work with negative numbers then your answer is 0.
Answer:
Number 1 is 12.
Step-by-step explanation:
{Solve by cross multiplication}
17 • x = 3 • (80 - x)
{Multiply 3 by distribution,}
17x = 240 - 3x
{Add 3x to both sides of the equation,}
20x = 240
{Divide through out by 20,}
20r/20 = 240/20
x = 12
Thus there were 12 pens :)
