Based on her results, if she flipped the coins another 50 times, she should expect to flip heads 20 times. If Jessica flips a coin 100 times and gets 40 times heads and the next time she flips a coin 50 times she should get 20 because, 100 divide 2 is 50 so you would have to divide 40 with 2 and get the answer of 20.
Answer:
B and D
Step-by-step explanation:
Answer:
Step-by-step explanation:
1) isosceles= two sides are congruent
2) 9x-13=4x+2
-4x
5x-13=2
+13
5x=15/5
X=3
Answer is c
15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2
The correct answer is 42x^4-24x^3+12x^2
