Answer:
The value of Mode is 2.43
Step-by-step explanation:
- To find the mode of the given data first we have to arrange it in a increasing order then find out mean and median of the given data
- 0.7,1.7,3,3.2,4.1,5.9,6.6,8.9 is in increasing order
- For finding the median we need to take the average of 4th and 5th terms because we have the no of terms in the sequence is even not odd so we need to take the average the 4th term=3.2 and the 5th term =4.1
- so average =(3.2+4.1)/2=3.65
- so the median is equal to 3.65
- For mean we have to take the average of the data
- so mean= sum of all data /no of data
- mean =(0.7+1.7+3+3.2+4.1+5.9+6.6+8.9)/8=4.26
- so by using the formula we can get mode
- <em>Mode=3×Median-2×Mean</em>
- Mode=3×3.65-2×4.26=2.43
- ∴The value of Mode is given as 2.43
U could use a protractor to help u
all u gotta do is measure it then minus the entire thing from 15
hope this helps u :)
Divide 252 by 21.
21 times 12 = 252
12 is 9 units shorter than 21.
so the answer is 12 inches by 21 inches
you work backwards from the area
area = width times length
a = wl
we know w is 9 units shorter than the length
so now we have the equation 252=(l-9) times l
plug in 21 for l and then solve there is your answer.
