Answer:
upper control limit = 6.058
lower control limit = 0.442
Step-by-step explanation:
Given that:
The numbers of sample n Mogul executives took = 8 Eagletrons at a time.
They find out that the average sample mean is 88.50 mph and;
the average range is 3.25 mph.
From the tables:
Control Limit = = 3.25
Therefore; the upper control limit and the lower control limit can be computed as follows:
upper control limit =
upper control limit = 1.864(3.25)
upper control limit = 6.058
lower control limit =
lower control limit = 0.136(3.25)
lower control limit = 0.442
Using logarithmic laws: log(a) + log(b) = log(ab)
log₄ (x + 9) + log₄ (x + 21) = log₄ [(x + 9)(x + 21)] = 3
Since we want the equation in terms of x, the next intuitive step is take 4 to the power of both sides, because the left hand side will simplify easily.
Solving the quadratic we get:
BUT, for the logarithmic equation to be defined, x > -9, so x≠ -25
Thus, the only solution is x = -5.
Answer:
