The range of given data set is 90.
Step-by-step explanation:
We are given the following data:
20.9, 33.1, 21.8, 58.5, 23.5, 110.9, 30.4, 24.9, 74.1, 60.3, 40.4, 45.4
When this data is arranged in ascending order, we get:
20.9 , 21.8 , 23.5 , 24.9 , 30.4 , 33.1 , 40.4 , 45.4 , 58.5 , 60.3 , 74.1 , 110.9
Range is a measure of dispersion and can be easily calculated.
Formula:
Thus, the range of given data set is 90.
Answer:
The money Rachael plan to collect for the shelter is <u>$345</u>.
Step-by-step explanation:
<u><em>There are some data missing in the question, so below is the complete question:</em></u>
Rachel is collecting donations for the local animal shelter. So far she has collected $245, which is 70% of what she hopes to collect. How much money does Rachel plan to collect for the shelter?
Now, to find the money Rachael plan to collect for the shelter.

The amount far she has collected = $245.
Percentage of amount she hopes to collect = 70%.
Now, to get the total money Rachael plan to collect:
<em>Dividing both sides by 0.70 we get:</em>
Therefore, the money Rachael plan to collect for the shelter is $345.
