The ratio of two computers is 3:2.
serious [3.7K]

Answer:

1. $82,500

2. 169 : 110

Step-by-step explanation:

The computation is shown below:

Given that

1. Ratio between two computers is 3:2

And the first computer cost is $55,000

Let us assume the price of the second computer be x.

As we know that

Product of extremes = Product of mean.

2 : 3 :: 55000 : x .

Now cross mutiplication is to be done

2x = $55,000 × 3

x = $1,650,000 ÷ 2

= $82,500

2. Now if the price of the 2nd computer rised by $2,000

So the new cost would be

= $82,500 + $2,000

= $84,500

Now the ratio would be

= $55,000 :  $84,500

= 169: 110

What is the difference between the mean and the median of the data set? {22, 8, 10 ,18 ,12, 20} 0 2 4 6
NikAS [45]

Answer:

Option A - 0

Step-by-step explanation:

Given : Data set {22, 8, 10 ,18 ,12, 20}

To find : What is the difference between the mean and the median of the data set?

Solution :

Data set in increasing order {8, 10 ,12,18, 20,22}

Mean is defined as the division of sum of set values by total number of values.

M=\frac{\sum x}{n}

Substitute the values we get,

M=\frac{8+10+12+18+20+22}{6}

M=\frac{90}{6}

M=15

So, The mean of the set is 15.

Median of even numbers is the average of two middle terms.

m=\frac{3rd+4th}{2}

m=\frac{12+18}{2}

m=\frac{30}{2}

m=15

So, The median of the set is 15.

Now, The difference of the mean and the median of the set is

d=M-m

d=15-15

d=0

Therefore,Option A is correct.

The difference of the mean and the median of the set is 0.
