Michael is organizing a game of chance for his class. he asks each student to pick a ribbon from a bag and then put it back into the bag. the bag has 12 yellow ribbons, 7 red ribbons, and 3 blue ribbons. if jane picks a ribbon, what is the probability that the ribbon will be yellow and what is the likelihood of this event?

The probability that the ribbon will be yellow is 0.54 and the event is likely to happen.

Step-by-step explanation:

Given: The total number of ribbons is in the bag= 12+7+3=22

If Jane picks a ribbon, what is the probability that the ribbon will be yellow is given by:-

We can see that probability that the ribbon will be yellow is between 0.5 and 1.

Therefore, the event is likely to happen.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
