--- What is the range of the following numbers?
12, 20,18,25,6

A. 5
B. 16 1/5
C. 18
D. 19
E. 25

D

Step-by-step explanation:

The range is subtracting the largest number and the smallest number.

largest number: 25

smallest number: 6

Range: 25 - 6 = 19

∠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: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
