Answer:
0.9783 = 97.83% probability that a can that gets shipped for use will be of perfect shape
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Shipped for use
Event B: Perfect shape
Probability of being shipped for use:
Perfect shape(0.9 probability) or unnoticeable dent(0.02 probability). So

Being shipped for use and being in perfect shape.
0.9 probability, so 
What is the probability that a can that gets shipped for use will be of perfect shape?

0.9783 = 97.83% probability that a can that gets shipped for use will be of perfect shape
So, 932.4miles (.75)=699.3miles are the miles that she wants to drive by the start of three days. so each day is 25% because of 75%/3=25%
In two days it will be 50% so, .50(932.4miles)=466.2 miles is the answer.
-4.6+1.8 is -2.8
You have to do simple math
The area of a circle is given by:

Where r is the circle's radius. In this case we have a diameter of 8cm so the radius 4cm. Using pi=3.14 we have that the area of the circle is:

So the area is 50.24 cm^2.
Answer:
We know that the figure has a symmetry
angle 1 = angle 2
angle 1 =180°-(18°+90°) = 180° - 108°=72°
Therefore, <em><u>angle 2 =72°</u></em><em><u>.</u></em>
