A.) It will take you 1,000,000 / 19 = 52,631.58 minutes = 52,631.58 / 60 = 877.19 hours = 877.19 / 24 = 37 days to spend $1 million.
b.) A penny is 1.55 mm thick, thus 1 million penny will be 1 million x 1.55 = 1,550,000 mm high.
c.) A quarter is 1.75 mm thick, thus 1 million quarter will be 1,000,000 x 1.75 = 1,750,000 mm high.
d.) 1000 mm = 1 m
Therefore, $1 million worth pennies will be 1,550,000 / 1,000 = 1,550 m high.
e.) $1 million worth quarters will be 1,750,000 / 1,000 = 1,750 m high.
I'm good at ratio tables. I'm actually doing one now.. If you still need help you can ask.
Answer:
x = 2
Step-by-step explanation:
Answer:
0.28 = (76 - 103)/σ (B)
Step-by-step explanation:
Let X be a random variable for capturing moths every night
Mean(μ) = 103
σ is the standard deviation
Pr(X<76) = 28%
Pr(X<76) = 0.28
For normal distribution, Z = (X - μ)/σ
Pr(X<76) = (X - μ)/σ
0.28 = (76 - 103)/σ
The equation to find the standard deviation is
0.28 = (76 - 103)/σ
