Answer:

fourth option

Step-by-step explanation:

The mean is calculated as

mean = \frac{sum}{count}

         = \frac{15+16+21+23+25+25+25+39}{8}

        = \frac{189}{8}

       = 23.6 ( to 1 dec. place )

The median is the middle value of the data set. If there is no exact middle then it is the average of the values either side of the middle.

15  16  21  23  25  25  25  39

                    ↑ middle

median = \frac{23+25}{2} = \frac{48}{2} = 24

The mode is the value that occurs most often, that is 25

Thus

mean = 23.6 , median = 24 , mode = 25

I need help<br> With this plz

Answer:

The discount is the same.

Step-by-step explanation:

We need to find the ratios of both discounts.

41/50 = 61.5/75

If the question is True, this means that the ratios should be the same. So we have to cross multiply to find the answer.

75*41 = 50*61.5 = 3075

These two multiplication problems both equal 3075. Since the ratios are equal, the discounts are also equal.

In Scott’s backyard, he has a windmill that makes 5 ¾ of a turn every hour. How many turns does it make for 1 ½ hours?
DanielleElmas [232]

Answer: 8 5/8 turns

Step-by-step explanation:

Hi, to answer this question we have to simply to multiply the number of turns that the windmill makes per hour (5 3/4) by the time asked (1 ½ hours).

Mathematically speaking:

5 3/4 x 1 1/2 = (5x4+3)/4 x (1x2+1)/2 = 23/4 x 3/2= 69/8 or 8 5/8 (mixed form)

In conclusion, the windmill makes 8 5/8 turns in 1 1/2 hours.
