Answer:
$203 billion
Step-by-step explanation:
984-781=203
B. 60 inches to 76 inches
C. 64 inches to 72 inches
D. 52 inches to 84 inches
If the mean height of the population is 68 inches and the standard deviation is 4 inches, 99.7% of the population will have a height within ranges of; 52 inches to 84 inches.
In statistics, Standard deviation is a measure of the variation of a set of values.
σ = standard deviation of population
N = number of observation of population
X = mean
μ = population mean
We know that at 99.7% the measurements would be within 2 standard deviations of the mean.
Mean of 68 inches
Standard Deviation of 4
The lower range = 68– 4(4)= 52 inches
The upper range = 68+ 4(4) = 84 inches
Thus, the option (D) 52 inches to 84 inches is correct after using the empirical Rule.

Answer:
Step-by-step explanation:
An average family of four (also living in Phoenix, AZ) uses 325,851÷365 gallons of water per day
then
An average family of four (also living in Phoenix, AZ) uses 892.74247 gallons of water per day
therefore
the number of families of four can one golf course provide water for :
80 000 000÷892.74247=89611.509
the number of families of four can one golf course provide water for :
[rounded to the nearest ten] 89610.

Answer:
Step-by-step explanation:
Givens
This situation can be described by the following equation
Where indicates the number of families that could use the 80 million galons of water.
Let's solve for
Therefore, around 250 families can be provided with one golf course.
