So ur numbers are : 3,3,4,5,5,5,6,8,8
and the median (middle number) is 5 <==
because 2 dots above the 3 means u have 2 threes....and 1 dot above the 4 means there is 1 four..and so on
The unit rate is going to be calories per serving....calories / serving
Food A :
150 / (3/4) =
150 * 4/3 =
600/3 =
200 calories per serving
Food B :
250 / (2/3) =
250 * 3/2 =
750/2 =
375 calories per serving
Therefore, Food A has fewer calories per serving <==
Answer:
x = 25
Step-by-step explanation:
.20x + .68(120 - x) = .54(120) (Distribute .68 to 120 and -x)
.20x + 81.6 - .68x = .54(120) (multiply .54 and 120)
.20x + 81.6 - .68x = 69.6 ( add .20x and -.68x)
-.48x + 81.6 = 69.6 ( subtract 81.6 on each side)
-.48x = -12 (divide -12 by -.48)
x = 25
1/4 of 20 is 5.
You divide 20 by 4.
Then you get 5, which is your final answer.
Have a nice day!
