Answer:
Option A is correct.
Step-by-step explanation:
Correlation coefficients tell us how strongly the two variables are associated.
A positive correlation is a relation when both the variables move together in the same direction. Like if value of first increases the other also increases.
When the correlation coefficient is greater than 0, this means that both variables are correlated.
So, the answer here will be :
A. There is a linear relationship between the variables, and whenever the value of one variable increases, the value of the other variable increases.
Answer:
Step-by-step explanation:
Answer:
the probability that at least one envelope is a yellow envelope is 16/21
Step-by-step explanation:
The probability that at least one envelope is a yellow envelope is P(Y);
P(Y) = 1 - P(Y)'
P(Y)' is the probability that no envelope is a yellow envelope.
Given;
red envelope = 1
blue envelopes = 3
green envelopes = 2
yellow envelopes = 3
Total = 9
Number of non-yellow envelope = 9 -3 = 6
(6 envelope are not yellow)
P(Y)' = P1 × P2 × P3
Since there is no replacement;
P(Y)' = 6/9 × 5/8 × 4/7
P(Y)' = 5/21
From equation 1;
P(Y) = 1 - 5/21
P(Y) = 16/21
the probability that at least one envelope is a yellow envelope is 16/21.
Answer:
(4,6)
Step-by-step explanation:
quadrant 1 always has positive coordinates so the only one with all positive coordinates is (4,6)
Maybe u add them up does it say area if so its multiply from it says a diff word I forgot it's subtract
