Answer:
D (-1, 5)
Step-by-step explanation:
In reflection along the x-axis,
x-coordonate remains unchanged and y-coordinate gets multiplied by -1
Once you have found the value of one of the variables(let's say x), you can substitute the value of the variable(x) into the variable(x) of one of the original equations to find the second variable.
9000 x .08 = 720
720 x 5= 3600
9000-3600= 5400
5,400
Answer:
The standard deviation is 5.29 kg.
Step-by-step explanation:
The standard deviation is the square root of the variance. Mathematically, we have that:

In this problem, we have that:

So
