Answer:
x = 8
Step-by-step explanation:
Chords AB and BD form an inscribed angle so <ABD = 5x
also given mAD = 80
Since inscribed angles are half the measure of their intercepted arc, angle <ABD is equal to 1/2(80 degrees), which is 40 degrees.
Now you have:
<ABD = 40
5x = 40
x = 8
Answer
x = 8
Answer:
C $126,720
Step-by-step explanation:
First hour: 1280 tickets
Second hour: 20% more than 1280 tickets
20% of 1280 = 0.2 * 1280 = 256
1280 + 256 = 1536
Second hour: 1536 tickets
First & second hour tickets:
1280 + 1536 = 2816
Total sales:
2816 * $45 = $126,720
Answer: C $126,720
i assume the line plot is the % difference, the original 95% vs 92% has a difference of 3%,
the 10 random values center around 3% and 3% has the most occurrences of the 10.
the average value for the 10 is 2.9%, so that is within .1 of the original 3%
so it should be significant, not sure what criteria you are supposed to use?
is there a p or z test involved?
Hope this helps!
