What is the mean and median of the lengths . <br> 10,31,36,36,38,42,47,48,49,and 52
Olin [163]

Answer:

Mean = 38.9  Median = 40

Step-by-step explanation:

When you find mean, you must add all the numbers together then divide by the amount of numbers.

10+31+36+36+38+42+47+48+49 + 52

==> 389

There are 10 numbers.

389 / 10

==> 38.9

To find median, you have to either find the middle number or find the two numbers that makes it equal. Since this range set is even, we use the second option.

(x + y ) / 2

38 + 42

==> 80

Divide by 2

80 / 2

==> 40

I need help. Please. Thank you.
Bond [772]

Answer:

Some answers include 42, 48, 54, etc.

Step-by-step explanation:

Since the number must be divisible by 2: the number must be even.

For a number to be divisible by 3, the sum of the digits must be divisible by 3.

4+2=6 which is divisible by 3

4+8=12 which is divisible by 3

5+4=9 which is divisible by 3

You can extend this logic for any number from 40 up to 99 since your number must be two digits and greater than 40.

If this helped, a brainliest would be greatly appreciated!
