What volume error (in ml, round to the nearest tenth) would occur in the measuring of 4 ml of a liquid ingredient if the improperly calibrated measuring device created a 12 % error in all measurements?

0.5 mL

Step-by-step explanation:

If the device wasn't properly calibrated, in volume the number can be estimated with a 3 rule:

100%4mL

12%x=12*4/100=0.48≈0.5mL rounding to the nearest tenth

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
