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

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

A number, n, is multiplied by - 5/8. The products is - 0.40 What is the value of n? It would also help if you would explain how

Kay [80]

I'm not sure if those numbers are negatives or thats just a hyphen but:

N(-5/8)=-0.40

Division is always the opposite of multiplication

-0.40/(-5/8)=0.64

N=0.64

What number must you add to complete the square?<br><br> x^2 + 8x = -3

KonstantinChe [14]

<span>x^2 + 8x = -3
</span><span>x^2 + 8x + 16 = -3 + 16
using a^2 + 2 a b + b^2 = (a+b)^2
</span><span>
</span>x^2 + 8x + 16 = 13

<span>(x +4)^2 = 13

answer : 16 is the number </span><span>you must add to complete the square</span>

shutvik [7]

Answer:

Statements 2, 4, and 5

Step-by-step explanation:

15≥22+x

okay so that's

22+x≤15

and that is

x≤-7
