Answer:
m = 2
Step-by-step explanation:
∠ GLI = 90°
∠ GLH + ∠ HLI = ∠ GLI , that is
9m + 25m + 22 = 90
34m + 22 = 90 ( subtract 22 from both sides )
34m = 68 ( divide both sides by 34 )
m = 2
Then
∠ HLG = 9m = 9 × 2 = 18°
Answer:
square root of 3 is 1.7 so put it closer to 2
square root of 8 is 2.8 so put it closer to 3
square root of 23 is 4.7 so put it closer to 5

Answer:
Assuming population data

Assuming sample data

Step-by-step explanation:
For this case we have the following data given:
736.352, 736.363, 736.375, 736.324, 736.358, and 736.383.
The first step in order to calculate the standard deviation is calculate the mean.
Assuming population data

The value for the mean would be:

And the population variance would be given by:

And we got 
And the deviation would be just the square root of the variance:

Assuming sample data

The value for the mean would be:

And the population variance would be given by:

And we got 
And the deviation would be just the square root of the variance:

Answer:
100
Step-by-step explanation:
0.5 / 0.005 = 100
Answer:
It will take the apprentice 24 days working alone
Step-by-step explanation:
Let the number of days it takes the apprentice be x
It will take the landscaper x/3 ( since he is three times faster)
The rate for both will be 60/6 = 10 sq m per day
Rate for apprentice is 60/x
rate for the boss is 60/x/3 = 180/x
Adding the rates together;
60/x + 180/x = 10
240/x = 10
240 = 10x
x = 240/10
x = 24 days
