A researcher is studying whether babies are able to identify a color accurately when given four choices. She wants to build a model that simulates the results of the study, assuming the baby is guessing and has a 25% chance of choosing the correct color.
Which model could be used to simulate the baby guessing the correct color?
O A Flip a coln. Landing on heads indicates a correct guess.
B. Roll a six-sided number cube. Rolling a 1 or 2 indicates a correct guess.
OC Spin a spinner divided into four equal sections. Landing on section 1 Indicates a correct guess.
D. Choose two marbles from a bag of 6 green and 6 red marbles. Choosing one marble of each color indicates a correct guess.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

question: how many people can she serve?

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
