In order to get the results shown,
the calculations must be done incorrectly. Ordinarily, instructions to round to a particular precision should be applied only to the final result(s). Here, you are expected to round every intermediate result. (This is generally considered to be WRONG!)

The numbers in the column

are simply the squares of the numbers in the column to its left. Round the squares to tenths. Their sum should be the value indicated in the bottom row.
The standard deviation is the square root of the variance,
√(99667.2) ≈
315.7

Answer:
<u>The equations for each function:</u>
- A(t) = 60 - 6t
- B(t) = 42 - 3t
<em>The lines plotted, see attached</em>
<u>The point at which both the snowmen have same height:</u>
- 60 - 6t = 42 - 3t
- 6t - 3t = 60 - 42
- 3t = 18
- t = 6
<u>The required interval is </u>
Answer:
578
Step-by-step explanation:
118 + 560 = 678
678 - 100 = 578
578 is your answer
20% of 16 which is. 10%=1.6 and another that would = 3.12
