How to determine relationship between two variables with standard deviation?

luda_lava [24]

Standard deviation is the average distance between two points on the graph. If the standard deviation (sd) is high, then the variables relationship is more spread out and unlike one another. The smaller the sd, the closer and less varied the variables are.

Joe can clear a lot in 2.5 hours. His partner can do the same job in 7.5 hours. How long will it take them working together?

irina [24]

Answer:

The time required by both persons to complete the work T = 1.458 hours

Step-by-step explanation:

Given data

Time required by Joe to clear a lot $T_1$ = 2.5 hours

Time required by his partner to clear a lot $T_2$ = 2.5 hours

Time required by both persons to complete the work by working together

$T = \frac{T_1 T_2}{T_1 + T_2}$

$T = \frac{(2.5)(3.5)}{2.5 + 3.5}$

T = 1.458 hours

Therefore the time required by both persons to complete the work T = 1.458 hours
