A. The answer is yes, because the distribution is approximately a bell curve.
The solution is
and 
Step-by-step explanation:
The expression is
and 
Using substitution method we can solve the expression.
Let us substitute
in 

Expanding and simplifying the expression, we get,

Let us use the quadratic equation formula to solve this equation,

Thus,
and 
Substituting y-values in the equation
, we get the value of x.
For
⇒ 
For
⇒ 
Thus, the solution set is
and 
The angles go in the same order as the sides across from them.
AB is the smallest side so angle C is across from it.
BC is the middle length so angle A is the middle angle. AC is the longest side so angle B is the largest angle.
Answer:
0.9538
Step-by-step explanation:
The computation of the proportion of variation in labor hours is explained by the number of cubic feet moved is shown below:
Here the R^2 coefficient of determination, would be determined and applied the same
R^2 = 1 - SSE ÷ SST
= 1 - 123.97 ÷ 2685.9
= 0.9538
