Answer:
Lin was better than Clare
Step-by-step explanation:
<h3>Given</h3>
<u>Clare
</u>
-
mean: 2,000 grams
- MAD: 275 grams
- median: 2,000 grams
- IQR: 500 grams
<u>Lin
</u>
-
mean: 2,000 grams
- MAD: 225 grams
- median: 1,950 grams
- IQR: 350 grams
<h3 /><h3>Question</h3>
- Which student was better at estimating the mass of the objects?
<h3 /><h3>Solution</h3>
<u>Comparing data for both Clare and Lin, we can see that:</u>
- mean - is same 2000 grams for both
- median - almost same, 2000 grams vs 1950 grams
- MAD - 275 grams vs 225 grams
- IQR - 500 grams vs 350 grams
<u>Conclusion</u>
- Lin was better at estimating than Clare
<u>Reason</u>
- Both students had measures of center (mean and median) very close to 2000 grams
- Lin got less variable responses as both the MAD and IQR were lower than Clare got
Answer: J. A translation of △XYZ to the right.
Step-by-step explanation:
I'll explain each bullet point one by one. A good hint is to pay attention to where the letters are.
-J is correct because the figure was shifted to the right.
-K is incorrect because if it was a reflection across the x-axis, the figure would be in Quadrant 3, or the bottom left.
-L is incorrect because if you pay attention to the letters, they are in the exact same place. If it was a reflection across the y-axis, the X' and Y' would switch places if you know what I mean.
-M is incorrect because if the figure was rotated 90°, point Z' would be furthest from the x-axis. In other words, the triangle would have been pointing up and not down.
-N is incorrect because if the figure was rotated 180° clockwise, the figure would have been in Quadrant 4, or the bottom right.
Given this information, the most appropriate answer is J.
I hope this helps! Pls give brainliest!! :)
They bought 5 trophies total
1st trophy cost $37.50
($18.50+$12.50+$4+$2.50=$37.50)
Each additional trophy cost $15
($12.50+$2.50=$15)
They spent $97.50 total
$97.50-$37.50=$60
Additional trophies $15
$15*X=$60
4 trophies=$60+$37.50 for 1st trophy
$60+$37.50=$97.50

Answer:
Step-by-step explanation:
<u>7.5% less than 120 </u>
- 120 - 7.5% of 120 =
- 120(1 - 7.5/100) =
- 120*0.925 =
- 111
