Answer:
53.57%
Step-by-step explanation:
We have to calculate first the specific number of events that interest us, if at least 3 are girls, they mean that 2 are boys, therefore we must find the combinations of 3 girls of 5 and 2 boys of 3, and multiply that, so :
# of ways to succeed = 5C3 * 3C2 = 5! / (3! * (5-3)!) * 3! / (2! * (3-2)!)
= 10 * 3 = 30
That is, there are 30 favorable cases, now we must calculate the total number of options, which would be the combination of 5 people from the group of 8.
# of random groups of 5 = 8C5 = 8! / (5! * (8-5)!) = 56
That is to say, in total there are 56 ways, the probability would be the quotient of these two numbers like this:
P (3 girls and 2 boys) = 30/56 = 0.5357
Which means that the probability is 53.57%
First, you would have to make the number of hours the x value and total cost the y value in the graph. Then, you would take however many hours to replace x, let’s say 5, and replace it for x in the equation y=8x+12, giving you y=8*5+12. You would then solve it by multiplying 8 and the x value, 5, giving you 40 in this example, and then adding 12, giving you 52 dollars for 5 hours.
To draw the line on the graph, you would start 0 hours with 12 dollars, 1 hour for 20 dollars, 2 hours for 28 dollars, and so on, adding 8 each time you add an hour.
Answer:
do this by first finding the greatest common factor of 0 and 23, which is 23
Then, we divide both 0 and 23 by the greatest common factor to get the following simplified fraction 0/1

$16.67 would be the price of each pencil. You divide 50 by 3 and get 16.6 repeating so you round it up to 16.67
