Answer:
Yes, it is a linear function
Step-by-step explanation:
The given equation, .8x + 1.5y = -6, is a linear function.
It is in the format of the linear equation Ax + By = C.
In this equation, 0.8 is A, 1.5 is B, and -6 is C.
So, it is a linear function.
Answer:
-1.3333
-1/2
3.25
Step-by-step explanation:
Ion need an explanation
First you would figure out what "x" equals. And then you would replace the "x" in your problem to figure out what the answer is.
The standard deviation of a sample is proportional to 1/√N where N is the sample size. In this case we are decreasing N by half, so we can write:
1/√(N/2) = √2 / √N
If we say that our standard deviation is proportional to 1/√N, the difference that occurred from decreasing the sample size by half resulted in an increase in the standard deviation by a factor of √2.
Therefore, the standard deviation is multiplied by √2.
Answer: - 35 / 12
Step-by-step explanation:
-2 1/4 - 2/3
= -9/4 - 2/3
= - 35 / 12
