Answer:
Margin of Error = 5.4088 ;
Confidence interval = (30.1 ; 40.9)
Interval estimate are almost the same
Step-by-step explanation:
Given that :
Population standard deviation, σ = 9.3
Sample size, n = 8
Xbar = 35.5
Confidence level = 90%
The confidence interval:
Xbar ± Margin of error
Margin of Error = Zcritical * σ/sqrt(n)
Zcritical at 90% = 1.645
Margin of Error = 1.645 * 9.3/sqrt(8) = 5.4088
Confidence interval :
Xbar ± Margin of error
35.5 ± 5.4088
Lower boundary = (35.5 - 5.4088) = 30.0912 = 30.1
Upper boundary = (35.5 + 5.4088) = 40.9088 = 40.9
(30.1 ; 40.9)
T distribution =. (30.5 ; 40.5)
Normal distribution = (30.1, 40.9)
Answer:
The equation of the line in standard form is
Step-by-step explanation:
The equation of the line in point slope form is
we have
so
step 2
Find the equation of the line in standard form
The equation of the line in standard form is
where
A is positive integer
B and C are integers
we have
Multiply by 4 both sides to remove the fraction
Step-by-step explanation:
So base on your question that ask to provide and end point of the four statement you give:
1.Endpoint(-1,9), midpoint:(-9,-10) - (-17, -29)
2.Endpoint(2,5), midpoint(5,1) - (4,5)
3.Endpoint(9,-10), midpoint(4,8) - i cant determine sorry
4.Find the point that is one-fourth of the way from (2,4) to (10,8) - also i cant.
If you’re solving for Y it will be
Y=-16/13+8x/13
If you’re solving for X it will be
X=2+13y/8
