First, we have to calculate the percentage that Sally got in the quiz: 22/40x100%=55%
The percentage of the questions she got wrong: 100%-55%=45%
Answer:
B is going to be half the intercepted arc
<ABC = 80
<CAB = 55
mARC(AB) = 90
mARC(BC) = 110
Step-by-step explanation:
Answer:
(a) Hypergeometric distribution
(b) 0.785384...
Step-by-step explanation:
(a) looking at the question, we see that
, suppose Evans studied s key terms, this implies that he has not studied 100 - s key terms. Suppose
if X = k, then k out of the s key terms he had studied appeared. But 10 - k out of 100 - s key terms he hasn't studied appeared. Thus X is an Hypergeometric distribution, X~HGeom(s, 100 - s, 10) with PMF:

1 ton = 2000 pounds
2000*16=32000ounces
32000/5 = 6400 parts
