M= 1/2
to find this you plug in the points into the the formula m=y2-y1 / x2-x1
m=3-6 / -4-2
m=-3 / -6
this simplifies to m=1/2
Answer:
308.2 - 293.8 = 14.4 km
14.4 - 2.3 = 12.1
So the library is 12.1 km from the park.

Answer:
4 and then 5
Step-by-step explanation:
4 times 4 is 16 and 5 times 5 is 25, the sqaure root of 20 is in between those two values.
Answer:
a) The new correlation coefficient should be the same: R = 0.72
Step-by-step explanation:
The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables.
It is a relative dimensionless measure, so it does not depend on the units of measurement of the variables involved.
If the variables are correlated in centimeters and kilograms, they will also be correlated in inches and pounds, and with the same relative magnitude.
So the answer is
a) The new correlation coefficient should be the same: R = 0.72
