<h2>1986, 1996</h2>Step-by-step explanation:
Given, Annual passenger revenue for the years 1980 to 2000 id=s modeled with the formula .
Here, is the annual revenue in millions of dollars,
is the number of years since January 1, 1980.
Revenue in a year was $ 790 million.
So,
So, after 6 yrs and 16 yrs from January 1, 1980, the Passenger revenue equals $ 790 million.
∴ Passenger revenue equals $ 790 million in 1986 and 1996.
Answer:
•Lower confidence limit = $155.2109
•Upper confidence limit ,= $174.5891
Step-by-step explanation:
We are given:
U = 17
x' = $165.40
S.d = $21.70
a = 10℅ (90℅ confidence interval)
For s.d(x'), we have:
S/√u =
= 5.2630
Therefore, S.E (x') = $5.2630
At a= 0.10 (90℅ confidence level)
and degree of freedom = 16 (17-1)
90℅ confidence interval all around sample mean, will be:
(x' ± ; a S.E (x')
= (165.4±(174.6)(5.2630)
(165.5±9.189)
($156.2109, $175.5891)
Answer:
or
Step-by-step explanation:
The question is
Find the slope intercept form of the line parallel to the line 5x+8y=120 passing through (4,5)
step 1
Find the slope of the given line
we have
isolate the variable y
The slope of the given line is m=-5/8
step 2
Find the slope of the line parallel to the given line
we know that
If two lines are parallel, then their slopes are the same
so
The slope of the parallel line to given line is m=-5/8
step 3
Find the equation of the line into slope intercept form
The equation of the line into slope intercept form is equal to
we have
m=-5/8 and point (4,5)
substitute and solve for b
