Answer:
31 deaths per month
Step-by-step explanation:
12 months in a year
372 / 12 = 31
6.4 is the answer hope this helps
If you mean h(4)
h(4)=(4)*2 -5(4)
=8-20
=-12
The answer will be-12
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
3 : 4 : 5 = 3² : 4² : 5² = 9 : 16 : 25
The answer is B.
Hope this helps.
