How can data be described by a single number

Mathematics
1 answer:
SpyIntel [72]3 years ago
3 0

Answer:

the arrangement of the values of a data set. measures of center [measures of central tendency] describes how data looks at the center; summarizes all of its values with a single number.

Step-by-step explanation:

Data that cannot be described using a single number are often shoehorned into random vectors of real-valued random variables, although there is an increasing tendency to treat them on their own. No seriously there is lol

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $22 monthly fee
vladimir2022 [97]
Company a = 22 + 0.07m
company b = 8 + 0.12m

We are looking for the time when the prices are equal. i.e. the price of company a = the price of company b

company a = company b
22 + 0.07m = 8 + 0.12m
22 - 8 = 0.12m - 0.07m
14 = 0.05m
m = 14/0.05
m = 280

Therefore, the two companies will cost the same if you talk for 280 minutes
