Answer:
x = ±2
Step-by-step explanation:
3x ^2 -4 = 8
Add 4 to each side
3x ^2 -4+4 = 8+4
3x^2 =12
Divide each side by 3
3x^2 =12
3x^2/3 = 12/3
x^2 = 4
Take the square root of each side
sqrt(x^2) = ±sqrt(4)
x = ±2

Answer:
positive association
linear association
Step-by-step explanation:
It is said that two variables A and B are related when the distribution of the values of one of the two variables differs according to the values of the other.
That is, when variable A grows then variable B also grows. This is known as positive correlation
When variable A grows then variable B decreases. This is known as negative correlation.
In the scatter plot you may notice that when variable A increases then variable B also increases, in an approximately linear relationship. Therefore it can be said that there is a positive and linear association.
The answer is the fourth and fifth option.
Answer:
M
Step-by-step explanation:
337 / 25 = 13.48
Round to the nearest whole number = 13

Answer:
Step-by-step explanation:
This triangle is a 45-45-90 triangle.
By using the image I posted, we can find x easily.
So, we have 
as one of the sides.
They hypotenuse, which is x is just 
Simplify and we get x =
