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

Can someone tell me what’s going on here
lora16 [44]

Answer:

c = 105 degres

Step-by-step explanation:

When two lines cross like that and form an x, the opposite sides are equal (so the angle below the 75 degree one is also 75 degees). Using this, you can figure out the rest.

If both the top an bottom are equal, you know that 150 degres are taken (75+75) and you know that there can only be 360 degres in total here, so you subtract 150 from 360 and get 210. Now you know that the last two sides together are 210, and since they are equal, you divide it by two to get 105 degrees.
