Answer:
± 8i
Step-by-step explanation:
note that 
= i
using the rule of radicals
• 
×

, hence
= ± 
= ± 
× = ± 8i
Answer:
Option B
Both distributions are nearly symmetric, so the mean and the standard deviation are the best measures for comparison.
Step-by-step explanation:
No. The absolute value of any number is always positive, as that is its 'absolute value'.
All we need to do is plug in the values and check.
15*60 + 10 * 20 ≥ 1100.
Is this statement true?
15 * 60 = 900
20 * 10 = 200
900+200 = 1100
Is the statement 1100≥1100 true?
Yes! So, (60, 20) is a solution because 1100 is greater than or equal to 1100.
