Answer:
7/78 as decimal is approximately: 0.08974
Hello from MrBillDoesMath!
Answer:
88
Discussion:
Order of operations has multiplication\division performed before addition\subtraction. So our equation is interpreted as
(y/8) + 19 = 30 => subtract 19 from both sides
(y/8) = 30 - 19 = 11 => multiply both sides by 8
(y/8) 8 = 8 * 11 =>
y = 88
Thank you,

Answer:
(I suppose that we want to find the probability of first randomly drawing a red checker and after that randomly drawing a black checker)
We know that we have:
12 red checkers
12 black checkers.
A total of 24 checkers.
All of them are in a bag, and all of them have the same probability of being drawn.
Then the probability of randomly drawing a red checkers is equal to the quotient between the number of red checkers (12) and the total number of checkers (24)
p = 12/24 = 1/2
And the probability of now drawing a black checkers is calculated in the same way, as the quotient between the number of black checkers (12) and the total number of checkers (23 this time, because we have already drawn one)
q = 12/23
The joint probability is equal to the product between the two individual probabilities:
P = p*q = (1/2)*(12/23) = 0.261

Answer:
Coefficient of Correlation
Step-by-step explanation:
Coefficient of Correlation is a value that ranges between -1 to 1, which is used to denote the closeness or linear relationship between two variables.
The closer the value of the coefficient is to -1 or 1, the stringer the relationship that exists between two variables.
A negative value suggests a negative relationship. Which means, as one variable decreases, the other variable increases.
A positive coefficient of correlation shows a positive relationship between two variables. Which means, as one variable increases, the other also increases.
If the Correlation coefficient is 0, it means there's no relationship between the variables.
