An average of 145 people visited a 4-day exhibition on the first 3 days. Another 205 people visited the exhibition on the fourth

Alenkinab [10]

Answer:

160 visitors.

Step-by-step explanation:

Given:

An average of 145 people visited a 4-day exhibition on the first 3 days, <u>means here average people visited in 3 days is given 145.</u>

Average = 145

Number of people, n = 3

Another 205 people visited the exhibition on the fourth day.

To find:

What is the average number of visitors per day ?

Solution:

<u>First of all we will find total number of people visited in 3 days:-</u>

As we know:

$Average=\frac{Sum\ of\ observation}{number\ of\ observation}$

$145=\frac{Sum\ of\ observation}{3}\\$

Multiplying both sides by 3

$145\times3=\frac{Sum\ of\ observation}{3}\times3\\435=Sum\ of\ observations$

Thus, we found that total number of people visited in 3 days is 435 and as 205 people visited in fourth day, then total number of people increased to

435 + 205 = 640

Now, sum of total observations( total number of people ) = 640

And number of observation ( number of days ) = 4

Now, we will calculate average number of visitors visit per day :-

$Average=\frac{Sum\ of\ observation}{number\ of\ observation}$

$=\frac{640}{4} \\=160\ visitors$

Thus, the average number of visitors per day is 160 visitors.

kykrilka [37]

Answer:

Step-by-step explanation:

We need to know how many hours left she needs to work, not how many weeks because it is for one week. It is not money because her requirment is not about how much money you make per week. It is also not jobs because in the requirements, there is nothing that talks about jobs.
