Notice y° and y° and 50°, are all three angles in a flat-line, namely "linear angles", and since a flat-line is always 180°.
B. I=PRT is the simple interest formula. 120 days is 4 months, or 1/3 of a year.
I=(4,000)(0.05)(0.33333)
I=$66.67
As this is probability, we can use the next formulas and tell how is this going to be:
P(A) = student on the dean's list
<span>P(B) = student taking calculus </span>
<span>P(A n B) = 0.042 </span>
<span>P(A) = 0.21 </span>
<span>So, P(B) = 0.042/0.21 </span>
<span>= 0.2
So the probability here is of 0.2</span>
So use -a/b and you get 6x as the slope and the parallel line would have the same slope
