Answer:
0.2109 or 21.09%
Step-by-step explanation:
In order to maintain the same price after two days, the stock must go up (U) on two days and go down (D) on two days, the sample space for this event is:
S={UUDD, UDUD, UDDU, DDUU, DUDU, DUUD}
There are 6 equally likely possible outcomes. The probability that the price of the stock will be the same as it is today is:

The probability is 0.2109 or 21.09%.
Like terms are going to have the EXACT same variables....or they can just be constants with no variables.
x^2 and 3x^2 are like terms
x^2 and x^3 are not like terms
8 and 9 are like terms
8x and 9y are not like terms
so ur like terms in ur problem are : 2y^3 and y^3
Answer:
Probably y=2x+60
Step-by-step explanation:
It seemed to fit best, dont count on my answer tho, not 100% sure :(
When I put the line through the points, the y intercept was around 50/60 and the slope is positive so it eliminated a few answers. then I chose y=2x+60 since that slope seemed more correct than a slop of 8.
