Answer:
Mean = 12.85714
Median = 15
Range = 15
Step-by-step explanation:
Mean:
5 + 15 + 10 + 20 + 15 + 10 + 15 = 90
90 / 7 = 12.85714
Median:
5, 10, 10, 15, 15, 15, 20
Median = 15
Range:
20 - 5 = 15
Step-by-step explanation:
Given that,
Perpendicular = 17 units
Hypotenuse = 25 units
We need to find the value of x.
Using Pythagoras theorem to find x.
Hypotenuse² = base²+perpendicular²
25² = x² + 17²
x = 18.3 units
So, the value of x is equal to 18.3 units. No, the sides do not form a Pythagorean triplet.
3*3=9
3 *-8i = -24i
8i *3 =24i
8i*-8i = -64i^2 or i^2 =-1. -64*-1=64
-24i + 24i =0
9+64= 73

= 
Answer:
x < 2
Step-by-step explanation:
8x -1 < 15
8x -1 (+ 1) < 15 (+ 1)
8x < 16
x < 2
