Answer:
See below
Step-by-step explanation:
B) The correlation coefficient is
, which can be determined by plugging the data into a TI-84 calculator.
C) A correlation coefficient of
indicates that the correlation between the independent and dependent variable (x and y in this case) is moderately strong with a positive correlation. The closer
is to 1, the stronger the positive correlation. The closer
is to -1, the stronger the negative correlation. If
is closer to 0, then there's no correlation.
Step-by-step explanation:
Slope = -5/5 = -1
Answer:

Step-by-step explanation:
Given,
Red marbles = 3,
Green marbles = 10,
So, the total marbles = 3 + 10 = 13,

Since, here replacement is not allowed,
Thus, the probability of getting a green marble and a red marble
= first red and second green + first green second red




Note : The probability of getting a green marble first and a red marble second
= 


The slope of function A is the coefficient of x, which is 6.
The slope of function B is the rise divided by the run, which is 3/1 = 3.
The appropriate choice is ...
... c) Slope of Function A = 2×Slope of Function B
