Answer:
Statistical sampling is drawing a set of observations randomly from a population distribution. ... By repeating the sampling operation a large number of times, perhaps 1000, we decrease the sampling error and increase the quality of the estimates.
Answer:
the second one
Step-by-step explanation:
Answer:
Alvin invested $110 at rate of 7% and invested $870 at rate of 5%
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem
Let
x------> the amount of money invested at rate of 5%
At rate of 7%
we have
At rate of 5%
we have
substitute in the formula
therefore
Alvin invested ($870-$760)=$110 at rate of 7%
Alvin invested $870 at rate of 5%
Well, keep in mind that the domain of a function is the entire set of possible values of the independent variable. To make it more clear, the domain is the set of all possible x-values, which will make the function work, and with real y-values as the output. So, the range would be the set of all of the second elements of an ordered pair (y-coordinates).
If you made a T chart like the picture you have above, you would have to put x (age of person) and y (books read).
So,
x = age of person
y = books read
