Answer:
The probability of both points falling in the same row or column is 7/19, or approximately 37%
Step-by-step explanation:
The easiest way to solve this is to think of it rephrased as "what is the probability that your second point will be in the same row or column as your first point". With that frame of reference, you can simply consider how many other points are left that do or do not fall in line with the selected one.
After selecting one, there are 19 points left.
The row that the first one falls in will have 3 remaining empty points.
The column will have 4 remaining empty points.
Add those up and you have 7 possible points that meet the conditions being checked.
So the probability of both points falling in the same row or column is 7/19, or approximately 37%
Answer:
See, that doesn't make sense.
First of all, 4 is the only number equal to 4. Sp, it'd be 9+4 = 13
Then I'm assuming you're also subtracting 4 from 13, so the answer would be 9.
Hope this helped, have a nice day.
The solution of the system of equation is the intersection point of the two quadratic equations, so we need to equate both equations, that is,

So, by moving the term -3x^3+20 to the left hand side, we have

Then, in order to solve this equation, we can apply the quadratic formula

In our case, a=5, b=-3 and c=-30. So we get

which gives

By substituting these points into one of the functions, we have

and

Then, by rounding these numbers to the nearest tenth, we have the following points:

Therefore, the answer is the last option
Step-by-step explanation:
the slope = 5/3
through (1, -1)
the equation :
y -(-1) = 5/3 (x -1)
y+1 = 5/3 x -5/3
y = 5/3 x -5/3 -1
y = 5/3 x - 8/3 or y = 5/3 x - 2⅔
21+21= 42 cookies minus 4 = 38 cookies
38/3= 12.66(round down to 12)
