The average rate of change is the slope.
The slope is equal
, if we were to do that for each set of points, we get the slope is always 8.
Thus the average rate of change is 8.
Answer: x = 2
Step-by-step explanation:
You need to subtract the 9from both sides to cancel out the 9 on the side of the x
Then you divide -18/-9 and you get +2

Begin by computing the number of all the possibilities:
It is given by the following formula:

Computing the number of favorable cases:
Exactly one pair of socks with the same color means either one magenta pair,
or one cyan pair, or one black pair or one white pair:
Number of possibilities with one magenta pair means"a magenta pair plus two socks with different colors from three possibilities" means 3 possibilities.
Same computation for the other colors.
Adding we get:

By definition, the probability of an event is the number of favorable cases over the number of possible cases:
The probability is
Answer:
1) 75 copies were sold
2)expected wage=720
Step-by-step explanation:
in this equation, y represents wages and x represents number of copies sold
lets take the trendline, y=6x+120
since the amount earnt is $570, we can take this to be our y variable
570=6x+120
450=6x
x=75
1) 75 copies r sold
2) this time we substitue the 100 for x
y=6(100)+120
y=600+120
y=720
2) expected wage=720
