What is the mean for this list of numbers? 4, 8, 12, 13 Answer and Explain how you got the answer

9.25

Step-by-step explanation:

Add up all of the numbers and then divide that answer by how many numbers you added up

Mean = 9.25

Step-by-step explanation:

Mean = (sum of numbers)/( how many numbers)

There are 4 numbers: 4, 8, 12, 13

Mean = (4 + 8 + 12 + 13)/4

Mean = 37/4

Mean = 9.25

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
