Two is equivalent to twenty and 84
0.2 is a decimal between 0.25 and 0.125
Step-by-step explanation:
Let S be the set of all the stores in the sample, A be the set of stores dealing with Asian companies and E but the set of stores dealing with European companies
i. The set of stores that deal with European or Asian companies is A ∪ E. The inclusion-exclusion principle states that |A ∪ E| = |A| + |E| - |A ∩ E| = 266 + 308 - 103 = 471. So P(A ∪ E) = 471/500 = 0.942
ii. E' = S - E. |S-E| = 500 - 308 = 192. So P(E') = 192/500 = 0.384
iii. |A - E| = |A| - |A ∩ E| = 266 - 103 = 163. So P(A - E) = 163/500 = 0.326
iv. Stores that do not deal with only one type of company, must deal with both Asian and European companies. We are given that |A ∩ E| = 103. So P(A ∩ E) = 103/500 = 0.206
Easy, right?
Then mark as brainlist!
The first thing you should know is the following conversion:
1h = 60min
What you can do to solve the problem is the use of a rule of three:
60 ---> 3.8
165 ---> x
Clearing the value of x we have:
x = (165/60) * (3.8) = 10.45
x = 10.45 mi
answer
she can walk 10.45 mi in 2 hours 45 minutes
