Afactory requires 84 machines to produce a given number of articles in 32 days. how many machines would be required to produce the same number of articles in 21 days?

56 Machines

Step-by-step explanation:

To solve this problem we need to use the rules of ratio and proportion.

We have:

84 Machines : 32 Days

x : 21 Days

Let x = number of machines required

84:32 can also be

x : 21 can also be

Now we can solve for x by first cross multiplying.

=

32x = (84)(21)

32x = 1764

Now to find for x, we have to divide both sides by 32

x = 55.125

Now since we cannot have 1/8th of a machine we round up to 56.

We need 56 machines to produce the same number of articles in 21 days.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
