Answer:
B and C
Step-by-step explanation:
The 2 smallest numbers have to add up to be bigger then the largest number in the set for it to be a triangle! I hope this helps!
The mean = 2,000
s = Sigma ( standard deviation ) = 300
M - 2 s = 2,000- 2 * 300 = 2,000 - 600 = 1,400
M + 2 s = 2,000 + 2 * 300 = 2,000 + 600 = 2,600
Answer.
Useful life of light bulbs within 2 standard deviations of the mean is:
A ) Between 1,400 and 2,600 hours
To be able to quickly solve this, we can temporarily make 5.47 into 547
Now, we can divide 547 by 12.
Now, we can round up from 45.5 to get 46.
However, we originally moved our decimal 2 places over, so now we must move it 2 places again.
46 ⇒ 0.46
The correct answer is $0.46
