Answer:
Number of month in first gym = 7
Number of month in second gym = 5
Step-by-step explanation:
Given:
First gym member ship cost = $75 per month
Second gym member ship cost = $50 per month
Total spending = $775
Computation:
Number of month in first gym = a
Number of month in second gym = b
So
a + b = 12....eq1
75a + 50b = 775 ....eq2
From eq 1 and 2
a = 7 month
b = 5 month
Number of month in first gym = 7
Number of month in second gym = 5
At x = -2, there is a blue dot, which is a local minimum, because it is below the x axis.
The dot is located at y = -4
The answer is Yes there is a local minimum at x = -2
The local minimum is y = -4
Answer:
Total money get from soda cans = $259.2
Step-by-step explanation:
Given:
Number of soda cases = 18
Number of soda can in each case = 24
Price of each soda can = $0.60
Find:
Total money get from soda cans
Computation:
Total money get from soda cans = Number of soda cases x Number of soda can in each case x Price of each soda can
Total money get from soda cans = 18 x 24 x 0.60
Total money get from soda cans = $259.2
Answer:
The 95% confidence interval for the true mean length of the shafts is ($3402.08, $4142.75).
Step-by-step explanation:
A (1 - <em>α</em>)% confidence interval for true mean (<em>μ</em>), when the population standard deviation is known is:
If the population standard deviation is not known, then the confidence interval for true mean is:
A 95% confidence interval for true mean is an interval estimate of the population mean. The interval has 0.95 probability of consisting the true value of the population mean.
It is provided that the 95% confidence interval for mean, based on a sample of size 30 is ($3402.08, $4142.75).
This interval implies that the true mean value is between $3402.08 and $4142.75 with 95% confidence.
Thus, the 95% confidence interval for the true mean length of the shafts is ($3402.08, $4142.75).
