<h3>
Answer: 0.93</h3>
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.2 + 0.8 - 0.07
P(A or B) = 0.93
Simple ....
we know to find slope is (y1-y2)/(x1-x2)
if we plug in what we know......
(-8,-6),(2,-3)
(-6--3)/(-8-2)
it turns into...
(-6++3)/(-8+-2)
(-3)/(-10)= 3/10
Thus, your answer is that she made no mistake. (C)
Since the golden ratio is approximately 1.618033989 which fits what you provided, then rounded to the nearest thousandth would be 1.618
Angles 2 and 4, and Angles 3 and 5 are supplementary. Supplementary means two angles add up to 180 degrees (aka a straight line).
