Answer:
0.000 000 000 000 000 000 000 000 000 01 g/cm³
or
10 fg/km³
Step-by-step explanation:
10^-29 is 1 in the 29th decimal place to the right of the decimal point.
An appropriate set of SI prefixes can be chosen so that the number isn't so difficult to write accurately. Using femtograms per cubic kilometer, we find that the equivalent number is ...
... (10^-29 g/cm³)×(1 fg/(10^-15 g))×(1 cm/(10^-5 km))³ = 10^(-29-(-15)-3·(-5)) fg/km³
... = 10 fg/km³
The value of x is 5. To find this distribute 1/3 and then add like terms.
Answer:
Mean = 160 births
Variance = 156.8 births
Standard deviation = 12.522 births
Step-by-step explanation:
The mean number of births resulting in twins is given by the sample size (n=8000 births) multiplied by the probability of twins in any birth (p=2%).
In a binomial distribution like this one, the variance is given by:
The standard deviation is simply the square root of the variance:
