Answer:
a) 0.4164
Step-by-step explanation:
Mean lifespan (μ) = 18.8 days
Standard deviation (σ) = 2 days
For any given lifespan 'X', the z-score is:

For X=12.04 days:

A z-score of -3.38 falls in the 0.036-th percentile of a normal distribution.
For X=18.38 days:

A z-score of -3.38 falls in the 41.68th percentile of a normal distribution.
The probability that a butterfly lives between 12.04 and 18.38 days is

In any triangle, the smallest side and smallest angle are opposite one another.
so in triangle DFG the shortest side is DG because it is opposite 52 degrees
in triangle EFG the shortest side is EG because it is opposite 47 degrees
I AM USING THE NUMBER IN THE DIAGRAM. i ASSUME THEY ARE CORRECT?
DG< EG
Answer:
6 minutes
Step-by-step explanation:
1 cube= 1 unit
1 Rod (Long)= 10 units
10 Rods (Longs)= 1 flat (1 flat=100 units)
10 flat =1 cube(1 cube=1000 units)
83×10= 830
2×10=20
830×20= 16,600
Just wanted to add more to help you understand why 83 is multiplied by ten and 2 is multiplied by 10. Its because when we use Base ten blocks, tens represent 1 Rod (Long)= 10 units. Hope it helps more.
The answer should be $1,255.50
