Question

Find the mean, median, mode, and range of these numbers 75,95,90,95,60,95,75,95,90
Plzzzzzz

Answer 1

Mean: 85 5/9

Median: 90

Mode: 95

Explanation:

~ Part I ~

1. To find the mean, let us take the average of the numbers through the addition of these values divided by the number of numbers:

75 + 95 + 90 + 95 + 60 + 95 + 75 + 95 + 90/9 = 770/9 = 85 5/9 (85.55.....)

~ Part 2 ~

1. Now let us arrange these numbers from least to greatest:

75 , 95 , 90 , 95 , 60 , 95 , 75 , 95 , 90 ⇒ 60,75 , 75 , 90 , 90 , 95, 95, 95,95

3. The median of this set would now be the middle number, which, (in this case) is ⇒ 90

~ Part 3 ~

1. The mode is known to be the number repeated most often, and from the previous question we see the numbers arranged in a benficial manner. Now we can straight away see that the number repeated the most is ⇒ 95

Answer 2

Answer:mean=85 5/9 mode=95 median=90

Explanation:

Mean=(75+95+90+95+60+95+75+95+90)➗9

mean=770 ➗ 9

Mean=85 5/9

Mode=95

To get median we first arrange in ascending order of magnitude

60,75,75,90,90,95,95,95,95

The middle number is the median which is 90
