Answer:
Mean = 6
Median = 6.5
Mode = 7
Step-by-step explanation:
4, 5, 6, 7, 7, 7,
Mean: Add all numbers then divide by numbers added
36/6 = 6
Median: Number in the middle
6 + 7 = 13 13/2 = 6.5
Mode: The number that appears most often in a set
there are 3 sevens
Answer:
1) ≤ 200 (less than or equal to 200 lb because Imani cannot have more than 200)
2) ≥ 45 (greater than or equal to 45 miles because Johnathan's drive is 45 miles or more)

Answer: Choice A) 212 square meters</h3>
========================================================
Explanation:
14.10 has four sig figs. The 0 at the end is significant. This measurement is accurate to the hundredths place. If the author wrote 14.1, then it would be accurate to the tenths place with three sig figs.
15.0 has three sig figs. The 0 is significant. If they wrote 15 or 15. then we'd be dealing with 2 sig figs instead; however they placed the 0 there to tell the reader "this measurement is accurate to the tenths place"
---------------------
Multiply the values given
14.10*15.0 = 211.5
Round that to three sig figs. We pick the smaller sig fig count to round to since we cannot be certain it is accurate to four sig figs. In a sense, we pick the weakest link and use that to determine rounding when it comes to multiplication and division.
This means 211.5 rounds to 212
If you would like to calculate 0.4 * x - 0.8 - 3 * x + 0.5 * x - 1.2, you can do this using the following steps:
0.4 * x - 0.8 - 3 * x + 0.5 * x - 1.2 = (0.4 * x - 3 * x + 0.5 * x) - 0.8 - 1.2 = - 2.1 * x - 2
The correct result would be - 2.1 * x - 2.
