Answer:
50%
Step-by-step explanation:
So, we divide by another 2! to cancel out double counting of two T's. Finally, if we divide all 6 different ways of getting exactly 2 heads (and 2 tails) in 4 flips by all possible outcomes 2 * 2 * 2 * 2 = 16 we would get the probability of exactly 2 heads in 4 flips.
The line and parabola intersect at about x=-2 and x=1.5 so the solution is A. x = -2
I can’t see the picture very well
Answer:
32
Step-by-step explanation:
15x+19=2(10x+2)
15x+19=20x+4
19-4=20x-15x
15=5x
x=3
PQ=QN
10x+2=
10(3)+2=
30+2=
32
Area of a circle is simple pi*r^2=A so rewriting the equation to solve for r^2 leads to r^2 = A/pi so plugging in numbers 682 for A and pi is just pi you get 682square meters/pi = r^2
