First you need to know some rules 2 numbers that are the same with coefficients divided : you differentiate those coeff
and multyplied :you sum up them
12x^8/3x^3= 4x^8-3=4x^5
20^2x=20^x*20^x
m^5*m^-7=m^5-7=m^-2
Answer:
3, -1
Step-by-step explanation:
Change 25% to .25. Multiply .25 by 50 to get 12.5. Subtract 12.5 from 50 to get $37.50
Step-by-step explanation:
The ways to get a total of four or less with two fair dices are:
(1,1)
(1,2)
(1,3)
(2,1)
(2,2)
(3,1)
out of 36 possible outcomes, so the probability is
P(<=4) = 6/36 = 1/6
