Answer:

Step-by-step explanation:

There are 40 trials, 16 out of those 40 trials resulted in two heads and one tail, which is what we are trying to find out of 120..

To do that, find 16/40 which gives you 0.4%

Next multiply 0.4% by 120 and you will get 48.

Answer:

The approximate number of employees who completed web analytics training are 245 .

Step-by-step explanation:

Formula

$Percentage = \frac{Part\ value\times 100}{Total\ value}$

As given

A survey of 600 randomly selected employees in Company X found that 150 of them completed web analytics training.

Part value = 150

Total value = 600

Putting in the above formula

$Percentage = \frac{150\times 100}{600}$

$Percentage = \frac{15000}{600}$

Percentage = 25%

Thus this shows that 150 employees who completed web analytics training from 600 employees are 25% .

As given

If there were 980 employees in the company .

Total value = 980

Percentage = 25%

Putting all the values in the formula

$25 = \frac{Part\ value\times 100}{980}$

$Part\ value= \frac{980\times 25}{100}$

$Part\ value= \frac{24500}{100}$

Part value = 245

Therefore the approximate number of employees who completed web analytics training are 245 .
