So if x= number of trees, and y= rental applications, the owner wants to see if increasing x will increase y. The correlation coefficient is between -1 and 1. If the number of trees really does have a positive impact on rental applications, the correlation coefficient would be close to 1. If there is absolutely no relationship, the coefficient would be near zero. If planting trees causes a DECLINE in rental applications, the coefficient would be close to -1.

abruzzese [7]

Answer:

Ella sold the each print for the cost of $57.21.

qwelly [4]

Answer: 708017151.707 m^3

Step-by-step explanation:

Volume of a sphere has the equation of

V=4/3(pi)r*r*r=4/3(pi)r^3

r=553 m

4/3(pi)553*553*553=4/3(pi)553^3=4/3(pi)169112377

=676449508/3(pi)=225483169.333(pi)=708017151.707 m^3

Where pi=3.14
