Answer:
Mean: 17
Median: 16
Mode: 10
Step-by-step explanation:
8, 10, 10, 11, 16, 17, 19, 21, 41
Median: (the middle number in the number list/data set) 16
Mode: 10
Mean: 8 + 10 + 10 + 11 + 16 + 17 + 19 + 21 + 41 = 153/9 = 17
<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>We know that:</u>
<u>Surface area is the area of the faces of the cuboid.</u>
<u>Work:</u>
- => 2(7 x 4) + 2(5 x 4) + 2(5 x 7)
- => 2(28) + 2(20) + 2(35)
- => 56 + 40 + 70
- => 166 units²
Hence, <u>Option C is correct.</u>
Hoped this helped.

Hello from MrBillDoesMath!
Answer:
3
Discussion:
Let the number be "n",
2n + 15 = 21 => subtract 15 from both sides
2n = 21 - 15 = 6 => divide both sides by 2
n = 6/2 = 3
Check: Start with 3. Double it (gives 6), add 15 to it ( 6 + 15) which gives 21/
Thank you,
MrB
