Answer:
2/5
Step-by-step explanation:
first, we convert the mixed fractions to improper fractions,
so then we find what
=
and that equals , which equals
. We can simplify that to 2/5

Answer:
So, the population mean is 3.66.
Step-by-step explanation:
We will calculate the average value by summing all the values and dividing by the size of sample.
We have population contains six members, with values 1,1,2,3,5,10.
Therefore, n=6.
We use the formula to calculate the population mean:
So, the population mean is 3.66.
Answer:
Step-by-step explanation:
First of all, to keep our numbers manageable, we are going to let year 2001 = 0 so year 2012 = 11. The coordinates that result from these years/population numbers are (0, 22200) and (11, 13950). Since this linear, we can plug those 2 coordinate pairs into the slope equation to find the rate at which the population is decreasing in people per year:
That means that the town is losing people at the rate of 750 per year. We can use that slop along with one of the coordinate points to write the linear equation representing this situation:
and
y = -750x + 22200. That answers part A.
Now for B we need to find y when x = 13 (remember we let year 2001 = 0, so year 2014 = 13):
y = -750(13) + 22200 so
y = 12450 people in the year 2014
