Answer: 0.2308
Step-by-step explanation:
A new bag of golf tees contains 10 red tees,10 orange, 10 green tees, and 10 blue tees. You empty the tees into your golf bags.What is the probability of grabbing out two tees of the same color in a row for you and your partner?
# of ways to succeed:: 4(10C2) = 4*45 = 180 ways
# of random pairs:: 40C2 = 780
P(2 of same color) = 180/780 = 0.2308
Therefore your answer is 0.2308
I hope this helps! :)

Answer:
x = 8
Step-by-step explanation:
because wy bisects XZ , XY and ZY are equal so ..
2x+3=3x-5
then x is 8❤

-5x = -17 - 13
-5x = -30
x = -30/-5
x = 6
Answer:
Her mistake is on line 2, setting the equations equal to each other.
Step-by-step explanation:
It appears that she misunderstood the requirements of question: find the intersections of the graphs of the two equations. The first one is a quadratic equation, (mentally picture that as a parabola). The second equation is linear. (Mentally picture that as a straight line with a slope of -2) They should have 2 points of intersection. When she combined them, she created a new quadratic equation and solved to "find the zeroes" where the parabola intersects the x-axis.
