Answer:
Step-by-step explanation:
Sample space is a set of possible outcomes of a random experiment.
A random experiment is an experiment whose outcomes can not be predicted.
Number of red balls = 6
Number of green ball = 1
Number of blue ball = 1
Let R denotes red ball, B denotes blue ball and G denotes green ball.
Sample space =
The lowest point on a quadratic function is the minimum. Not all quadratic functions have minimums.
So your friend bought 1 set of brush and 5 bottles of paint
you bought 2 brushes and 7 bottles of paint
1 bottle=3.69
friends cost+your cost=51.69
total you bought 3 brushes and 12 bottles
each bottle is 3.69
12*3.69=44.28
totalcost=51.69=3brushes+12bottles
51.69=3brushes+44.28
minus 44.28 from both sides
7.41=3brushes
divide both sides by 3
2.47=1brush
1 set of paint brushes=$2.47
