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.
Garth
Which model could be used to simulate the baby guessing the correct color?
O A Flip a coin. Landing on heads indicates a correct guess.
3. Roll a six-sided number cube. Rolling a l 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.

Cost = $86.67

Step-by-step explanation:

Given

Yards = 4⅓ (missing part of the question)

Cost per yard = $2.00

Required

Determine cost of chains produced in 10 minutes

If 4⅓ yards is made in a minute, then

4⅓ * 10 yards are made in 10 minutes

Total = 4⅓ * 10

Total = 13/3 * 10

Total = 130/3 yards

Cost of a yard of chain is $2.00.

Cost of 130/3 yards would be:

Cost = $2.00 * 130/3

Cost = $260.00/3

Cost = $86.67 (approximated)

Hence, the required cost is approximately $86.67
