Answer:
Third one one
(1 x^8/ 2^2y^5)^3
Step-by-step explanation:
Quotient of power: a^m/a^n = a^(m-n)
[(x^3y^-2) /(2^2x^-5y^3)]^3 = (x^8/ 2^2y^5)^3
So. It's third option
Answer:
3. B.
1. 3551.
Step-by-step explanation:
3. For two equations to have infinite solutions, the equations must be the same.
y = -5x + 6
5x + y - 6 = 0
Multiply the whole thing by 2.
10x + 2y - 12 = 0
B.
1. Michelle rides roller coasters 3 times and plays the super swing 5 times, which means that A = 3 and B = 5.
Marty rides the roller coasters 5 times and plays the super swing 1 time. That means C = 5 and D = 1.
So, your answer will be 3551.
Hope this helps!
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.
Slope of a line is calculated by dividing the change in y by the change in the horizontal component, x. That is most commonly known as "rise over run". Now, considering a horizontal line, there is no "rise" because the rate of change in y is zero. Therefore, the slope is zero.
