1) Find the Mean (Ungrouped) Earthquake Strengths Twelve major earthquakes had Richter magnitudes
shown here.
7.0, 6.2,7.7, 8.0, 6.4,6.2,7.2,5.4,6.4,6.5,7.2,5.4

6.633...

Step-by-step explanation:

(7.0 + 6.2 + 7.7 + 8.0 + 6.4 + 6.2 + 7.2 + 5.4 + 6.4 + 6.5 + 7.2 + 5.4) / 12

6.6333333

The mean is an average, so you add all the numbers together and divide by the number a values added together.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
