$315, i cant give a thorough explanation since i did it all in my head but basically amal gets 5 portions of the money and Salma gets 9, meaning she gets 4 more, so if 4 portions is $252 then it cant be any of the others since they are too low or way too high, $315 is the only reasonable one.
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
QUESTION :-
what is the value of x to the nearest whole number?
ANSWER :-
![\cos( \theta) = \frac{base}{hypotenuse} \\ \cos(30) = \frac{x}{24} \\ \frac{ \sqrt{3} }{ \cancel2} = \frac{x}{ \cancel{24}} = \frac{x}{12} \\ 1.732 = \frac{x}{12} \\ 12 \times 1.732 = x \\ x = 20.7](https://tex.z-dn.net/?f=%20%5Ccos%28%20%5Ctheta%29%20%20%3D%20%20%20%5Cfrac%7Bbase%7D%7Bhypotenuse%7D%20%20%5C%5C%20%20%5Ccos%2830%29%20%20%3D%20%20%5Cfrac%7Bx%7D%7B24%7D%20%20%5C%5C%20%20%5Cfrac%7B%20%5Csqrt%7B3%7D%20%7D%7B%20%5Ccancel2%7D%20%20%3D%20%20%5Cfrac%7Bx%7D%7B%20%5Ccancel%7B24%7D%7D%20%20%3D%20%20%5Cfrac%7Bx%7D%7B12%7D%20%20%5C%5C%201.732%20%3D%20%20%5Cfrac%7Bx%7D%7B12%7D%20%20%5C%5C%2012%20%5Ctimes%201.732%20%3D%20x%20%5C%5C%20x%20%3D%2020.7)
