Answer:
x^3-3x=0
+3x
x^3=3x
ok so that means that that number cubed is the same as a number squared so
x = 0
x = -sqrt(3)
x = sqrt(3)
im going say the answer is mostly likely 0 but it could be the other ones

Answer:
Option A
Step-by-step explanation:
Given that in a study of the relationship between geographical mobility (number of times a person has changed residences) and number of friends, Pearson's r^2 is reported as .40.
r square, being the coefficient of determination explains the variablity of one variable due to the variability of the other. Here Mobility explains 40% variation in the number of friends is right answer.
Option B is wrong because r = ±6324, so cannot say positive or negative.
Similarly option c is wrong because we are unsure whether negative correlation. Option d is wrong since 16% is not right .
6×100
6×90
