Answer:
<ADC=131°
Step-by-step explanation:
<ADC= <ADB+<BDC
We need to substitute the angle measures and simplify to get:
<ADC=89+42
This simplifies to give us:

The correct answer from the given options is the first choice.
Answer:
<em>The answer to your question would be D.</em>
<em>D. Range: 20</em>
<em>Mean: 10</em>
<em>Median: 9</em>
<em>Mode: none</em>
Step-by-step explanation:
1, 2, 3, 8, 9, 12, 14, 20, 21
Range: 21 - 1 = 20
Mean: 1 + 2 + 3 + 8 + 9 + 12 + 14 + 20 + 21 = 90/9 = 10
Median: 9
Mode: there are no mode in the following given data set.
Yes, it is. The reason is that 0.4 is equal to 0.40, which is greater than 0.04.
no?? 0 out of anything would just be zero! it could be a 0 or a 000.00/anything and the answer would still be zero!
it's rational, but not reasonable ;)
8*t^2 / 13*s is the correct answer
Hope this helps!
