Determine the percentage of the tip
First, we calculate the amount paid



The percentage of the tip is then calculated using:





Answer:
0.15866 is the probability of the average fracture strength of selected 100 pieces of glasses that of exceed 14.3.
Step-by-step explanation:
Given that, the strength of a tempered(x) a glass has average 14.1 and has standard deviation 2.
, 
n=number of selected pieces= 100.
The probability that the average fracture strength of 100 pieces of this glass exceed 14.3 is



= 1 - 0.84134
=0.15866.

Answer:
3.166
Step-by-step explanation:
It is not fully done but I put it to the thousandths if you want full answer, it is 3.16666667
Part a= cuboid
Part b= To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.*I tried my best sorry*
