find mean median mode class interval 0 10 is 5 10 to 20 is 3 20 to 30 is 4 30 to 40 is 3 40 to 50 is 3 50 to 60 us 4 60 to 70 is 7 amd 70 to 80 is 9 plz give answer asap ​

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
