Answer:
7
4
Step-by-step explanation:
The <u>actual values</u> are shown on the given graph as <u>blue points</u>.
The <u>line of regression</u> is shown on the given graph as the <u>red line</u>.
From inspection of the graph, in the year 2000 the actual rainfall was 43 cm, shown by point (2000, 43). It appears that the regression line is at y = 50 when x is the year 2000.
⇒ Difference = 50 - 43 = 7 cm
<u>In 2000, the actual rainfall was </u><u>7</u><u> centimeters below what the model predicts</u>.
From inspection of the graph, in the year 2003 the actual rainfall was 44 cm, shown by point (2003, 40). It appears that the regression line is at y = 40 when x is the year 2003.
⇒ Difference = 44 - 40 = 4 cm
<u>In 2003, the actual rainfall was </u><u>4</u><u> centimeters above what the model predicts.</u>
Answer:
I give you an example
the formula said x^m/x^n= x ^(m-n)
if m=n
x^m/x^m=1
but x^(m-m)=x^0=1

Answer:
310.23
Step-by-step explanation:
circumference is radius * 2
to get radius from circumference, divide circumference by 2
18.84 / 2 =9.42
area for circle:
pi * r^2
3.14 * 9.94^2
3.14 * 98.8
310.23
