Answer:
<ABC = 27
< BAC = 126
Step-by-step explanation:
<C = <B since it is an isosceles triangle. We know this since AC - AB
<C = 27 so <ABC = 27
The sum of the angles of a triangle = 180
A + B+ C = 180
A + 27+27 = 180
A + 54 =180
A = 180-54
A =126
< BAC = 126
HI!
First of all, there are total 12 + 2 + 6 = 20 pairs of socks.
Probability of getting a pair of white socks the first time is 12/20.
Probability of getting a pair of gray socks without replacement, if first one was white, is 2/19
Therefore the probability t<span>hat she will take a white pair and gray pair</span> without replacement is 6/95 (I multiplied the two probabilities)
Let me know if there are any other questions!
The answer is b because 95 confidence is interval for the mean lifespan
Answer:

Step-by-step explanation:
2 3/5 can be changed into 2.6 and then you multiply it by 8. if you need to put it back into fraction form from 20.8 it would be 20 4/5
