Answer:
Yes
Step-by-step explanation:
Yes, because there is a constant rate of change. It is and will always be constantly increasing by 1.5.
To be a linear line you have to have a constant rate of change.
<span>The mean of a set of data is 148.87 and its standard deviation is 68.29. Find the z score for a value of 490.19
the z-score is given by:
z=(x-</span>μ<span>)/</span>σ
plugging in the values in the expression we get:
z=(490.19-149.87)/68.29
z=340.32/68.29
z=4.9835
Answer:
The solution to the system of equations be:

Hece, option B is correct.
Step-by-step explanation:
Given the system of equations

Multiply x − 3y = 6 by 2: 2x-6y=12

so




so the system of equations becomes

Solve 8y = -8 for y

Divide both sides by 8





subtract 6 from both sides


Divide both sides by 2


Therefore, the solution to the system of equations be:

Hence, option B is correct.
667.302 would be the correct answer, I did it in a calculator
