Find the mean ,median and mode of the weights of people shown

Step-by-step explanation:

Given

Solving (a): The mean

This is calculated using:

Hence:

Solving (b): The median

Arrange in ascending order

So, the position of the median element is:

The 5th element is 76kg

Hence:

Solving (c): The mode

In the given data

Because it has a frequency of 2 (the highest), others have 1

they will manufacture 8496 cars

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
