The mean of the data set(9,5,y,2,x)is twice the data set (8,x, 4,1,3).What is (y-x)

pantera1 [17]

Answer:

y - x = 16

Step-by-step explanation:

Explanation:-

Step(i):-

Given data set A is 9,5,y,2,x

Mean of the Data set A

= $\frac{9 + 5 + y + 2 +x}{5}$

= $\frac{16 +x+y}{5}$

Given data set B is 8, x, 4, 1, 3

Mean of the Data set B

= $\frac{8+ x+4+1+3}{5}$

Step(ii):-

Mean of the Data set A = 2 X Mean of the Data set B

$\frac{16 +x+y}{5} = 2 X \frac{16+x}{5}$

On simplification , we get

16 +x + y = 2( 16 +x)

16 + x + y = 32 + 2 x

16 + x + y - 32 - 2 x = 0

y - x -16 =0

y - x = 16

20 liters of mixture contain milk nad water in the ratio 5:3 of 4 liters of the mixture are replaced by 4 liters of milk find th

pantera1 [17]

Answer:

7:3

Step-by-step explanation:

5 + 3 = 8

The ratio is

5 milk : 3 water : 8 total

Milk is 5/8 of the total.

Water is 3/8 of the total.

The 20-liter mixture contains:

5/8 * 20 = 12.5 liters of milk, and

3/8 * 20 = 7.5 liters of water

4 liters of the mixture contain:

5/8 * 4 = 2.5 liters of milk, and

3/8 * 4 = 1.5 liter of water

When you remove 4 liters of the mixture from 20 liters of the mixture, you end up with

12.5 L - 2.5 L = 10 L milk, and

7.5 L - 1.5 L = 6 L water

Now you add 4 liters of milk. Now you have

10 L + 4 L = 14 L milk

6 L water

The new ratio of milk to water is 14:6 = 7:3
