Rikki decided to collect data determine if a runners time and speed are correlated. She determined the data to have a correlation coefficient of -0.5 what does this r value indicate A-no correlation
B-a strong positive correlation
C-a weak positive correlation
D-a negative correlation

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
