The arithmetic mean provides a single measure for a certain population, also called the average.
The sum of a set of numbers divided by the total number of numbers in the set is known as the arithmetic mean or arithmetic average in mathematics and statistics.
The ratio of the total number of observations divided by the sum of all the given observations is known as the arithmetic mean. For instance, if the data set contains 5 observations, it is possible to get the arithmetic mean by adding all 5 of the given observations and dividing by 5.

Answer:
The watch is cheaper in Geneva, Switzerland by a value of £20
Step-by-step explanation:
To get the city in which the watch is cheaper, what we need to do is to express the price of the watch in the same currency.
Since pounds is also used in the b part of the question, it would be easier working with it.
In Geneva, the price of the watch is 193.75 CHF
from our conversion formula;
£1 = 1.55 CHF
£x = 193.75 CHF
We cross multiply to get the value of x
(193.75 * 1)/1.55
= 193.75/1.55 = £125
We can see that the watch costs less in Geneva and higher in Manchester
By how much is it cheaper?
We can calculate this by subtracting the value in Geneva from the value in Manchester
That would be 145-125 = £20 cheaper

Answer:
3
Step-by-step explanation:
15/3=5
9/3=3
18/3=6
answer is 3 I believe.
It has been to us that there are a total number of 220 people.
The box plot has been shown to us. We know that in a box plot from the Lower Quartile to the Median the data is 25% of the total amount of data. Likewise, from the Median to the Upper Quartile it is 25% again and from the Upper Quartile to the last data. It is again 25%.
Now, as per the box plot given to us, 6 hours is the Lower Quartile, therefore, more than 6 hours at the computer will have 25%+25%+25%=75% of the total people. The number of total people is 220. Therefore, the number of people who spend more than 6 hours at a computer will be:
75% of 220=
Thus, Option A is the correct option.
