The probability of all possible outcomes is always 1, meaning 100%.
In this case the probability of rolling a 1,2,3,4,5, or 6 is:
1/6+1/6+1/6+1/6+1/6+1/6
6(1/6)
6/6
1
Answer:
see below
Step-by-step explanation:
If suffices to look at the last term. It must simplify to 4/(3w²), so the exponents of z must match in numerator and denominator, and the ratio of constants must reduce to 4/3.
The exponents of z have the right values in choices B and D, but the ratio of constants only matches in choice D. Looking at the rest of choice D, we see that we can factor 6w²z² from both numerator and denominator, then factor 2 from the remaining numerator to make it match the desired form.

(-2) + 6 + 1 = 1 + 6 + (-2)
-2 + 7 = 7 - 2
5 = 5
6 1/10 + 5 9/12 = 11 17/20
20+2x=3x subtract 2x from both sides
20=x after 20 miles the total cost for both companies will be the same
PROOF
20+2(20)=3(20)
20+40=60
60=60
