Answer:
C.
Step-by-step explanation:
Let , and . From statement we know that , which is equivalent to the following linear algebraic formula:
(1)
(2)
Then, the coordinates of point B on AC are:
Which means that correct answer is C.
This would not be binomial; the probabilities are not independent, since the balls are drawn without replacement.
A: 292892 b: 2972 c: 9272726: d: 196373
The answer is B, hope this helped
The 3 inside angles of a triangle need to equal 180 degrees. Looking at the larger outside triangle the top angle is 30 and the lower right angle is 60.
30 + 60 = 90
The lower left angle needs to be 180 - 90 = 90 degrees.
That angle is split into two angles with one given as 70.
This means X needs to be 90 - 70 = 20 degrees.
x = 20
