Answer:

Step-by-step explanation:

d=rt We need to solve for r and to do this we need to isolate r

to isolate r we must move t to the other side of equal sign because you are multiplying rt you will divide on the other side (cause you always do the opposite operation on the other side)

so it will look like rt/d=r and this is your answer d=rt/t

and prob. 2

21-p=2l+2w we need to isolate w to solve for w

so first move 2l to the other side and it becomes negative

21-p-2l=2w

now that we are multiplying with 2 we need to isolate w , to do this we need

to divide 2 by all the equation on the other side

21-p-2l

_____ =W

2l + -1 + -L =W

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
Mode=3×Median-2×Mean
Mode=3×3.65-2×4.26=2.43
∴The value of Mode is given as 2.43
