When you flip a coin twice, you have a 50/50 chance of it land on heads or tails.
The possible combinations for fliping a coin twice:
HH (heads/heads both times)
T/H(Tails/Heads)
H/T(Heads/Tails)
or the one you're looking for...
T/T (Tails/Tails both times)
You have a 1/4 chance of getting tails both times.
Answer:
h(x)=x²+6 and g(x)=8x-5
prove that hg(x)=19
Step-by-step explanation:
step 1: hog(x)=h[g(x)]
step 2: h(8x-5)
step 3: h(8x-5)= (8x-5)²+6
step 4: (8x-5)(8x-5)+6
step 5: 16x² +15x +6
Answer:
-b
Step-by-step explanation:
-(a+b) = -a - b
-a -b + a = -b
( the -a + a cancel each other out )
