Step-by-step explanation:
The average rainfall when you add all 10 years of rainfall up and divide by 10 is an average of 59.946 inches of rain each year. The equation for the data is y = -0.53x + 64.45, this means that the rainfall is getting less each year at a -0.53 inches of rain each year.
x = year (2004 would be 4, etc)
Answer:
Step-by-step explanation:
The continuous compound formula is
where P is the principle or starting value, r is the growth rate in decimal form, and t is the time in years. For us:

which would probably round to just 3848 people.
Answer: y = 1/4x - 4
Step-by-step explanation: write it in slope intercept form y = mx + b
Answer:
A solution to a system of equations means the point must work in both equations in the system. So, we test the point in both equations. It must be a solution for both to be a solution to the system. Hope this helps.
To find the percentage of a number, first, convert it to a decimal and then multiply.
To convert a percentage to a decimal, move the decimal point over 2 spaces to the left. That makes 80% = 0.80
Then multiply 0.80 by 30.
0.80 • 30 = 24
