Answer:
Lower control limit: 310
Upper control limit: 550
Step-by-step explanation:
The problem states that the average chicken breast contains 430 calories, and the standard deviation in caloric content of the chicken breast population is 30 calories.
a) What are the lower and upper control limits for this chart if these limits are chosen to be four standard deviations from the target?
The lower control limit is the mean subtracted by four standard deviations. So 430 - 4*30 = 310;
The upper control limit is the mean added four standard deviations. So 430 + 4*30 = 550;
Answer:
see below
Step-by-step explanation:
y = a cos ( bx)
The amplitude is |a|
y = -2cos (3x) so the amplitude is |-2| = 2
The period is 2pi/b
period is 2pi/3
Answer:
3 + 3/4x
Step-by-step explanation:
it is 3 up and 4 left so y over x for the the slope. mx +b
Here's the equation for one year:
0.04(15000) + 15000
Because it is 9 years:
0.36(15000) + 15000
We can make it simpler:
1.36(15000)
Multiply:
20400
Their balance is $20400
