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.
A. If it has a 60% mark up price of $120 that would be $60 so the total would be $180. B. If there selling the bike at what the store is selling it for it would be $126 because 30% of $180 is $54 so subtract $54 from $180 and you will get $126 C. The store would make a total profit of $6.
Answer should be A, I hope this helps! Btw you shouldn't be asking about something thats on a test haha but thats fine! We all do it sometimes!

Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>let's solve:</h3>
to find <u>how far the ladder is from the foot of the </u><u>wall </u>
we will use tan function because we are given opposite and angle
we need to find adjacent
let adjacent be BC
we will use a little bit algebra to figure out BC
