Answer:
Claire's lemonade is stronger
Step-by-step explanation:
Jennie's lemonade
2/2=1
3/2=1.5
Claire's lemonade
3/3=1
4/3=1.334
Jennie's lemonade has more water in the lemonade per lemon, so Claire's is stronger.
I don't know if I used proportions though.
Hope I did this correctly!

Answer:
<em>Tommy earned $55</em>
Step-by-step explanation:
<u>Proportions</u>
Tommy and Mark made $88 raking leaves for Mrs. Bopp. They were paid the same rate and Tommy raked for 5 hours while Mark raked for 3 hours.
The total time both raked is 5+3=8 hours. The rate Mrs. Bopp paid them was $88/8 = $11 per hour.
Tommy raked 5 hours, so he earned 5*$11 = $55
Tommy earned $55
Using statistical concepts, it is found that the mean is most affected by extreme values.
-----------------------
- The mean of a data-set is the <u>sum of all values divided by the number of values</u>, and thus, if an extreme measure is included in the data-set, it will be included in the calculation of the mean.
- The median is the measure that <u>separates the upper 50% of the data-set from the lower 50%</u>. If an outlier is included, it may have an small effect on the data-set, as the value of the middle may change, but the change will be small compared to the mean, thus, the mean is most affected.
