Answer:
-22.5
Explanation:
Use the average rate of change equation
f(b)-f(a) / b-a
f(b) = f(0) = 3(.25)^0 = 3
f(a) = f(-2) = 3(.25)^-2 = 48
(3-48)/ 0-(-2)
(-45) / 2
-22.5
Compute the correlation coefficient for the data set. (2,19), (3,22), (4,26), (5,20), (6,35), (7,30), (9,40), (10,42), (11,35)

Answer:
The correlation coefficient of the data is 0.8679.
Step-by-step explanation:
The formula to compute the correlation coefficient is:
From the data provided compute the values of ∑ XY, ∑ X, ∑ Y, ∑ X² and ∑ Y².
The values are computed in the table below.
Compute the correlation coefficient as follows:
Thus, the correlation coefficient of the data is 0.8679.
Answer:
a. 337/365 or 92.3%
Step-by-step explanation:
There are 365 days in a year. There are 28 days in February. So the number of non-February days is 365 − 28 = 337. The probability that a randomly selected person is not born in February is therefore 337/365 or 92.3%.
