Answer:
S1 is congruent to S2
Step-by-step explanation:
60 degrees
100+120+80+x=360
300+x=360
x=60
s=10
Basically, the range rule-of-thumb is that the range is generally about four times the standard deviation.
<u>First, we find the range:</u>
Range=Maximum-Minimum
Range=100-60
Range=40
<u>Next, divide the range by 4 to get the standard deviation</u>
Range=4(Standard Deviation)
40=4(Standard Deviation)
10=Standard Deviation
Therefore, s=10, which is the standard deviation
Explanation:
The original set
{78, 55, 22, 16, 84, 75, 33, 69, 58, 59}
sorts to
{16, 22, 33, 55, 58, 59, 69, 75, 78, 84}
The min and max are 16 and 84 respectively
Midrange = (min + max)/2 = (16+84)/2 = 50
