Answer:
Step-by-step explanation:
Given that there are two machines available for cutting corks intended for use in wine bottles.
X1 = diameter of I machine and X2 = diameter of II machine
X1 is N(3.04, 0.02) and X2 is N(2.9, 3.1)
Acceptable is mean =3 and std dev = 0.1
a) 
b) 
Both are certain events.

1) As we can see this is a Linear Equation written in the Slope-intercept form:

Note that "m" stands for the slope of the line, i.e. the measure of how steep a line is.
In the given equation, we can state that the slope is always accompanying the "x" therefore, the slope is m= 7
2) In addition to this, the y-intercept also called the Linear Coefficient is given by the letter"b" and represents the y-coordinate that the graph intercepts. Thus the y-intercept is -6
So we can state the following as the answers:

And that is the answer
Answer: Donna is wrong. Mean weight is 7.1kg
Step-by-step explanation:
Calculate the mean for the bricks:
4 bricks have a mean weight of 5kg = 4 * 5
5 bricks have a mean weight of 9kg = 5 * 9
1 green brick is 6kg
= (4 * 5 ) + ( 5 * 9) + 6
= 71kg
Mean = 71 / (4 + 5 + 1)
= 7.1 kg
