The transformation is B- vertically stretched
Answer:
a) 21+30+10+4+19+31+7+17+4=148
148 divided by 10= 14.8
b) 148+17=165
165 divided by 11= 15
Step-by-step explanation:
In math, the mean is the average of a set of numbers. To find the mean of a data set, add up all of the numbers in the set, and then divide that total by the amount of numbers in the set.
Answer:
960
Step-by-step explanation:
The Original is unknown.
528 is only 55% of the original value (as 45% was removed).
It is called the Unitary Method What i am going to do now:
<em>528/55 = 9.6</em>
We divided by 55, as we wanted to be left with only 1% of the orignal so we can times by 100, and get 100% of the original value.
So now we know that 1% of the total is 9.6.
To find 100%, we times this value by 100, and therefore we get:
<em />
<em>9.6 x 100 = 960</em>
This is our answer. If you still don't understand what I have done here, search google for the unitary method and there are plenty of videos on google for further understanding.
