Answer:
the number of dreams that include people you know out of 28 is 21
Step-by-step explanation:
Here is the complete question:
It is believed that about 
of our dreams involve people that we know.
So the expression to describe the number of dreams that feature people you know if you have "d" dreams is:
Now using the above expression we can predict number of dreams that include people you know out of 28. Here 28 represents number of dreams i.e. "d". So expression becomes:
Now simplify the above expression:
= 
= 
= 
Hence the number of dreams that include people you know out of 28 is 21
Because this is a two-way table, the answer would be that 166 people were polled in total. Why? Well, there are lots of corresponding patterns leading up to this answer. We can easily find the answer by looking at the problem two different ways:
1st way: Identifying the missing solution by rows.
27 + 21 = 48 and 42 + 76 = 118, so we can find the missing value by adding 69 and 97 to get 166.
2nd way: Identifying the missing solution by columns.
27 + 42 = 69 and 21 + 76 = 97, so we can find the missing value by adding 48 and 118 to get 166, our missing solution.
Your final answer: 166 people were polled. Your answer would be D. If you need to better understand this, let me know and I will gladly assist you.
Answer:
a) 
= 1 x 1 x 1 x 1 x 1 = 5
b) 2 x 2 x 2 x 2 x 2= 
= 32
c) 
= 20 x 20 x 20 = 8000
d) 7 x 7 x 7 x7 = 
= 2401
