Answer: The description are as follows:

Step-by-step explanation:

Correlation coefficients is a statistical measure that measures the relationship between the two variables.

(a) r = 1, it means that there is a Perfect positive relationship between the two variables. If there is positive increase in one variable then other variable also increases with a fixed proportion.

(b) r = -1, it means that there is a perfect negative relationship between the two variables. If there is positive increase in one variable then other variable decreases with a fixed proportion.

(c) r = 0, this is a situation which shows that there is no relationship between the two variables.

(d) r = 0.86, this is a situation  which shows that there is a fairly strong positive relationship between the two variables.

(e) r = 0.06, it is nearly zero which represents that either there is a very minor positive relationship between the two variables or there is no relationship between them.

(f) r = -0.89,  this is a situation  which shows that there is a fairly strong negative relationship between the two variables.

Is g(x) = (x-1)(x+1)(x-3i)(x+3i) the factored form of f(x) = x^4+8x^2-9
user100 [1]

Answer:

Yes

Step-by-step explanation:

(x-1)(x+1)(x-3i)(x+3i)

FOIL ( x-1) (x+1) = x^2 -x+x-1 = x^2 -1

FOIL (x-3i)(x+3i) = x^2 +3ix -3ix -9i^2 = x^2 -9(-1) = x^2 +9

(x-1)(x+1)(x-3i)(x+3i) = (x^2 -1) (x^2 +9)

FOIL again

x^4 +9x^2 -x^2 -9

x^2 +8x^2 -9

This is the factored form
