The average mean is equal to the sum of numbers divided by the total numbers, which means that the mean of 230 with 80 numbers gives that the sum is 230*80 = 18400, if you apply the formula described in the beginning. Since 4 numbers are known and are<span> 145,156,210, and 255, their sum is </span>766. The sum of the list is equal to the sum of the numbers without the sum of 4 known numbers, so it's equal to 18400 - 766 = 17634, from which we can see that the Mean = (Sum Of List)/(80 - 4)
= 17634/76
= 232.02
Answer:
94.4$
Step-by-step explanation:
3x6%= 18%
using cross multiplication you can find 18% of 80
18/100=x/80 =14.4$
then you add the 18% of 14.4$ to the original 80$ which comes out to 94.4$
Hope this helped you out a little!
192 quarts there are 4 quarts in 1 gallon
3/4 x 21
=
3/4 x 21/1
=
63/4
I think to solve for this problem we need to subtract the given amounts.
19 - (-39) = 19 + 39 = 58
