Step-by-step explanation:
Answer:
75.36 is the answer.
Step-by-step explanation:
trust me bro.
6x^2-12x=-34
x^2-2x=-34/6
x^2-2x=-17/3
x^2-2x+1= -17/3+1/1
x^2-2x+1= -14/3
(x-1)^2= -14/3
x-1= √-14/3
Final answer: No solution (you cannot find the root of a negative number)
Answer: (145820, 170180)
Step-by-step explanation:
Formula for confidence interval for population mean ( when population standard deviation is unknown ) :

, where n= sample size
= sample mean
s= sample standard deviation
= two-tailed t-value for significance level of (
).
We assume that the salary of CFA charterholders is normally distributed .
Let x represents the salary of CFA charterholders .
As per given , we have
n= 36

Degree of freedom : df = 35 [ df= n-1]
s= $36,000
Significance level : 
Using t-distribution table ,

95% confidence interval for the average salary of a CFA charterholders :-

Hence, the 95% confidence interval for the average salary of a CFA charterholder : (145820, 170180)
