Answer:
Step-by-step explanation:
given that the following linear regression prediction equation: Y = 12 + –1x
Here slope = -1
Whenever regression slope is negative, we can say that the two variables x and y are negatively correlated.
In other words, when y increases x decreases and vice versa.
The relationship between the variables is negative or inverse.
The graph of this line with negative slope shows the line as moving from top left to bottom right
Here slope = -1
Hence for unit increase in x, there is one unit increase in y.
Answer:
8 x 8 x 8 x 8 = 4096
Step-by-step explanation:
Its an exponent which means you multiply 8 by itself 4 times to get 4096.
Answer:
obtuse angle
Step-by-step explanation:
Answer:
x=9
Step-by-step explanation:
so the angles of a triangle add up to 180 and since it shows two angles of 60 which makes 120, you have 60 more degrees which means A has to be 60 degrees. so if all of the angles are the same then the side lengths are the same so since it already shows one side =9 then x=9
