This is called system of equations.
Step-by-step explanation:
This combines two equations and then lines them up to a system.
Answer:
The 95% confidence interval is ( 27.126 , 34.674)
Step-by-step explanation:
Given
The t critical value at 0.05 level = 2.023 for the df = 39
Confidence interval = 95%
Mean
Substituting the given values we get -
Hence, the 95% confidence interval is
( 27.126 , 34.674)
Answer:
16
Step-by-step explanation:
6+8+10+20=44+16= 60 divided by 5 is 12
Answer:
Step-by-step explanation:
This is an Annuity question. It is asking for recurring monthly payment(PMT). <em>You can use a financial calculator to solve it. I am using (Texas Instruments BA II plus)</em>
Since the payments occur monthly , adjust the interest rate to monthly rate and multiply 40 years by 12 since we have 12 months in a year<em>.</em>
Total duration of investment ; N = 40*12 = 480
Interest rate; I/Y = 5.75% /12 = 0.4792%
Future value; FV = 6,000,000
Present value ; PV = 0
then CPT PMT = 3,222.912
Therefore $3,222.91 should be deposited each month to achieve the goal.
Answer: ok so for 5 and 125 it is 65 and 25
for 1 and 9 it is 5 and 3 and for 4 and 9 it is 13/2 and 6
