Answer:
π/36 sec-1
Step-by-step explanation:
From the question we are given the formula below
s = rwt ..........eqn(1)
Where s= π/3m, r=3 m, t= 4 sec
We were not given value of " w" which implies we are required to find out values of" w"
We can make " w " the subject of the formula from eqn(1)
s = rwt
w= s/(rt)........eqn(2)
Then substitute for the values in eqn(2)
w= (π/3m ) / ( 3m × 4 sec)
= π/36 sec-1
Hence, the value of the
missing variable is π/36 sec-1
Answer:
Stem Leaf
5 | 7
6 | 3 3 5 8 8
7 | 0 0 2 3 4 6 7 7 8 8 9
8 | 1 2 7
9 | 0 7 7
10 | 9
11 | 4 6 8
Notation: 5|7 means 5.7 and 11|4. means 11.4
Step-by-step explanation:
For this case we have the following data:
5.7 7.2 7.3 6.3 8.1 6.8 7.0 7.6 6.8 6.5 7.0 6.3 7.9 9.0 8.2 8.7 7.8 9.7 7.4 7.7 9.7 7.8 7.7 11.6 11.4 11.8 10.9
The first step on this case is order the dataset on increasing way:
5.7 6.3 6.3 6.5 6.8 6.8 7.0 7.0 7.2 7.3 7.4 7.6 7.7 7.7 7.8 7.8 7.9 8.1 8.2 8.7 9.0 9.7 9.7 10.9 11.4 11.6 11.8
Then we can construct the stem leaf plot like this:
Stem Leaf
5 | 7
6 | 3 3 5 8 8
7 | 0 0 2 3 4 6 7 7 8 8 9
8 | 1 2 7
9 | 0 7 7
10 | 9
11 | 4 6 8
Notation: 5|7 means 5.7 and 11|4. means 11.4
