Paul [167]

If the mean of the data set is 32.6. Then the number of pages he read in 5 days is 163.

Mean is simply defined as the average of the given set of numbers. The mean is considered as one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.

Han recorded the number of pages that he read each day for five days.

If the mean of the data set is 32.6 pages. Then the total number of the pages he read till now, will be

Let the total number of the pages be x. Then we have

$\rm \dfrac{x}{5} = 32.6\\\\x \ = 5 \times 32.6 \\\\x \ = 163$

A laboratory technician needs to make a 63-liter batch of a 20% acid solution How can the laboratory technician combine a batch

Gre4nikov [31]

Let x be the volume (liters) of pure (at 100%) acid needed
Let y be the volume (liters) of the other acid (at 10%) needed
The final solution will be:
a) x+ y = 63 liters, AND their respective concentration in acid: is
100% x & 10% :y that will generate 63 liters at 20%
b) x +0.1 y = 63x 0.2 = 12.6

Let's solve this system of 2 equations:

x + y =63
x + 0.1 y = 12.6

Solving it will give you:

x= 7 liters at 100%
y = 56 liters at 10%
