Answer:
x = 10
Step-by-step explanation:
In the last step, you can see that the fraction 
has been multiplied by its reciprocal 
, making it cancel out. The reciprocal has been multiplied to both sides, so all you need to do is multiply 
· :
6 · 5 = 30
3 · 1 = 3
<u><em>So now you should have the fraction:</em></u>
x = 
<u><em>But, you can still simplify the fraction by dividing 30 by 3:</em></u>
x = 10
ABC is a isosceles triangle
AC = BC
so
<A = <B
2x - 20 = x + 8. solve for x
subtract x to both sides
2x - 20 - x = x + 8 - x
x - 20 = 8
add 20 to both sides
x - 20 + 20 = 8 + 20
simplify
x = 28
<A = <B = 28 + 8 = 36
<C = 180 - 2(36)
<C = 180 - 72
<C = 108
Answer
B. 108 degrees
The mean : 2.5 million
S D = 0.6 million
2.5 - 2 · 0.6 = 2.5 - 1.2 = 1.3 million
2.5 + 2 · 0.6 = 2.5 + 1.2 = 3.7 million
Chebyshev theorem : at least 3/4 of the data lie within 2 standard deviations of the mean.
