A scientist has two solutions, which she has labeled Solution A 60% and Solution B 75% Each contains salt. She knows that Solution A is salt and Solution B is salt. She wants to obtain ounces of a mixture that is salt. How many ounces of each solution should she use

The correct answer is:

$2 per share.

Explanation:

He paid $12000 total, at a rate of $8 per share. This means he bought 12000/8 = 1500 shares.

He sells these 1500 shares for $15000; this means he received 15000/1500 = $10 per share.

This means he made 10-8 = $2 profit per share.

Answer:

$2

Step-by-step explanation:

Cost of 1 share = $8

He bought Shares for amount $12,000

So, He bought number of shares =

                                                       =

Now he sold 1500 shares for amount $15000.

So, S.P. of 1 share =

                              =

So, S.P. of 1 share = $10

C.P. of 1 share = $8

So, profit = S.P. - C.P.

                = $10-$8

                =$2

Thus he made $2 as profit on each share.

Answer:

Hence,

Mean=15.9

Median=16

Interquartile=14.5

Step-by-step explanation:

On arranging our data in the increasing order we get the data set as:

5   5   8   8   13   14   16    16    19    22   23   27   31

Now we find the mean as:

Now, we know that the median is the central tendency of the data and lie in the middle of the data.

Hence, by looking at the data we see that the middle value of the data is 16.

Hence, Median=16.

Now, the lower set of data is:

5   5   8   8  13   14

Now, the lower quartile is calculated as:

The middle value of the lower set of data is:

8     8

Hence, the lower quartile is middle of 8,8.

i.e.

similarly the upper set of data is:

16    19    22   23   27   31.

Similarly the upper quartile is calculated as:

Hence, interquartile range (IQR) is calculated as:

Hence,

Mean=15.9

Median=16

Interquartile=14.5
