Answer:
The confidence interval is (24116.3878,24883.6122).
Step-by-step explanation:
We are given the following information in the question:
Population mean, 
= $23,500
Sample mean,
= $24,500
Sample standard deviation,s = $2,800
Sample size, n = 146
Confidence interval:
Putting the values, we get,
The confidence interval is (24116.3878,24883.6122).

i know that one for a fact u just have to mutiply
Battery is down currently = 2/5
Battery drains at the rate of 1/9 every hour.
Remaining battery life of Vera = 1 -2/5 = 3/5
Let y we the number of hours battery will last.
So, 1/9 y = 3/5
y = 27/5
y = 5 + 2/5 hours
y = 5 hrs and 24 mins
So battery will last another 5 hrs and 24 mins.
hope this helps:)
The answer is 9y^2x(the 2 goes on top were the arrow is ) Hope this was helpful!
Answer:
Circumcenter of a triangle is formed by joining the perpendicular bisectors of three sides of triangle.
As we draw perpendicular bisectors of three sides, they will intersect at one point(say O) which lies inside the circle.
From that point of intersection, draw a circle touching each of the vertex of a triangle and we get a circumcircle. And O becomes centre of the circle.
Hence, circumcenter lies inside the triangle.
