CHEGG Currently in a classroom, there are four students ages 6, 7, 8, and 9. If two new students ages 6 and 9 walk into the room, what happens to the mean and standard deviation of the ages?

∠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°

answer: huh

step-by-step explanation:

6 and 24

step-by-step explanation:

6 x 4 = 24
