Answer:
x= 12/5 so A
Step-by-step explanation:
10^4+6x=8 that’s one equation I made up :)
Answer:
$393.50+/-$19.72
= ( $373.78, $413.22)
Therefore, the 95% confidence interval (a,b) = ($373.78, $413.22)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = $393.50
Standard deviation r = $50.30
Number of samples n = 25
Confidence interval = 95%
z value(at 95% confidence) = 1.96
Substituting the values we have;
$393.50+/-1.96($50.30/√25)
$393.50+/-1.96($10.06)
$393.50+/-$19.7176
$393.50+/-$19.72
= ( $373.78, $413.22)
Therefore, the 95% confidence interval (a,b) = ($373.78, $413.22)
Answer:
Step-by-step explanation:
Given
Required
Determine the quotient
See attachment for complete process.
First, divide 125x^3 by 5x
Write 
at the top
Multiply 
by
Subtract from 125x^3 - 8
i.e.
Step 2:
Divide 50x^2 by 5x
Write 
at the top
Multiply by
Subtract from 50x^2 - 8
i.e.
Step 3:
Divide 20x by 5x
Write 
at the top
Multiply by
Subtract from 20x - 8
i.e.
Hence:
