Answer:
16 and 48
Step-by-step explanation:
let the 2 integers be x and 3x ← ratio 1 : 3
Then
3x - x = 32 ← difference between the integers
2x = 32 ( divide both sides by 2 )
x = 16
and 3x = 3 × 16 = 48
Since magnitude of difference is 32
We can also express the difference as
x - 3x = 32
- 2x = 32 ( divide both sides by - 2 )
x = - 16
and 3x = 3 × - 16 = - 48
The 2 integers are 16 and 48 or - 16 and - 48
First we find the mean (average)
(90 + 82 + 88 + 78 + 93) / 5 = 431/5 = 86.2
now we find the absolute value of the difference of the data points and the mean
90 - 86.2 = 3.8....| 3.8 | = 3.8
82 - 86.2 = -4.2...| -4.2 | = 4.2
88 - 86.2 = 1.8....| 1.8 | = 1.8
78 - 86.2 = -8.2 | -8.2| = 8.2
93 - 86.2 = 6.8....| 6.8| = 6.8
now we find the mean (average) of those values
(3.8 + 4.2 + 1.8 + 8.2 + 6.8) / 5 = 24.8 / 5 = 4.96 <== the MAD
∠A= 112.5°, ∠B=67.5°, ∠C is 67.5° and ∠D 112.5°.
Answer:
The number between -1 and 1 is 0 ( zero)
