The problem is an arithmetic sequence with:
a₁ = 206,300
an = 208,400
n = 2013 - 2000
n = 13
To find the annual increase, use this following formula
an = a₁ + d(n - 1)
d represents the annual increase
Input the numbers
an = a₁ + d(n - 1)
289,400 = 206,300 + d(13 - 1)
289,400 = 206,300 + 12d
289,400 - 206,300 = 13d
83,100 = 12d
12d = 83,100
d = 83,100/12
d = 6,925
The annual increase is $6925
Answer:
x=9
Step-by-step explanation:
logx (531441) = 6
Changing this to an exponential
x^6 =531441
Take the 6th root of each side
(x^6)^1/6 = (531441)^1/6
x =9
Answer: 10 bags
Step-by-step explanation:
First we must calculate the field area. Assuming it is a rectangle then its area equals the product of its length times its width

You use 8 pounds of fertilizer per 1,000 square feet
So the amount of fertilizer you should use is:

As the fertilizer comes in bags of 50 pound then you need

Since you can not buy 9.2 bags then we round up to the next whole number.
Finally you need 10 bags of fertilizer
To summarize a set of data using an interval scale, you would use a box plot.
