If you would like to know how much do two apples cost, you can calculate this using the following steps:
o ... the cost of one orange
a ... the cost of one apple
1 * o + 1 * a = $1.05
2 * o + 3 * a = $2.75
_______________
o + a = 1.05 ... o = 1.05 - a
2 * o + 3 * a = 2.75
2 * (1.05 - a) + 3 * a = 2.75
2.1 - 2 * a + 3 * a = 2.75
a = 2.75 - 2.1
a = $0.65
o = 1.05 - a = 1.05 - 0.65 = $0.4
2 * a = 2 * 0.65 = $1.3
The correct result would be: Two apples cost $1.3.
Answer:
four sixths + three fifths.
Step-by-step explanation:
1 8/30 = 38/30.
4/6 + 3/5
= 20/30 + 18/30 = 38/30.
8, 11, 12, 13, 16, 42
Add together and divide by 6 to get the mean.
102/6 = 17
Find the middle of the data for the median.
(12 + 13)/2 = 12.5
The mean is 17, the median is 12.5, and the mean is more affected by the outlier. 17 (the mean) is not a good measure of center.
