Answer:
65.22% probability that it is in compliance of both safety and sanitary standards
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Number of restaurant in compliance of both safety and sanitary standards.
First I will find those not in compliance, using a Venn's set.
Set A: Violation of sanitary standards.
Set B: Violation of safety standards.
<em>5 were in violation of sanitary standards, a total of 6 were in violation of safety standards, and 3 were in violation of both.</em>
This means that
<em>At least one:</em>
So
8 are in violation of at least one of these standards.
So 23-8 = 15 are in compliance of both safety and sanitary standards.
What is the probability that it is in compliance of both safety and sanitary standards?
15 out of 23
15/23 = 0.6522
65.22% probability that it is in compliance of both safety and sanitary standards

Answer:
Surface Area= 498 cm²
Step-by-step explanation:
To calculate the surface area of this composite shape, work out the area of each face and add them together (break this composite figure into two shapes)
- Calculate the areas of the different sized faces
7 x 7 = 49
12 x 7 = 84
12 x 7 = 84
- Now, multiply these areas be number of corresponding faces
49 x 2 = 98
84 x 2 = 168
84 x 2 = 168
- Add these areas together
98 + 168 + 168 = 434
Now do the same for the shape above it
2 x 2 = 4 → 4 x 2 = 8
2 x 7 = 14 → 14 x 2 = 28
7 x 2 = 14 → 14 x 2 = 28 = 64
Add the surface areas together : 434 + 64 = 498 cm²
