B.16 because 800 divided by 50 is 16
Answer: mean=87, median=87.5 and range=18
Step-by-step explanation:
Mean:
First add all the numbers
78+95+77+92+87+79+94+86+88+94 = 870
Then you divide the answer by counting the numbers
870÷10
=87
Median:
First arrange the numbers in ascending order (from smallest to largest)
77, 78, 79, 86, 87, 88, 92, 94, 94, 95
pick the two middle numbers which is 87 and 88
then you do ![\frac{87+88}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B87%2B88%7D%7B2%7D)
= 175÷2
= 87.5
range = Largest number - smallest number
= 95-77
= 18
6 ft into meters would be 1.829, rounding to to nearest tenth would be 1.8
B - 8x
To find this, combine like terms.
8x - 2x is 6x, then add the two x's on the side to bring it back to 8x.
Hope this helps!
