Thats an exponential function The variable x is an exponent so that is why its called exponential.
Answer:
We have to find the 90% confidence interval for the mean
Given sample size
Sample mean
Population standard deviation
Here the confidence level is 90% then
And
The 90% confidence interval is
Here is the critical value at 0.05
From the tables
Now the 90% confidence interval is =
=
=(3840.44, 4133.56)
Hence the 90% confidence interval for the mean is (3840.44, 4133.56)
This is a 30-60-90 triangle
opposite side of rigt angle=2x
opposite side of 60 degrees is x√3
opposite sides of 30 degree is x
the right angle is at the base of the building so therefor
200=x
2x=distance from surveor to top of building and x√3=height of building
x=200
200√3≈346.41
the answer is 346.41 feet
11/3, 1.3, 1.34 Is the correct way to put it. PLZ give me the Brainliest answer. :)
A = pi r^2
A = 5^2 pi
A = 25 Pi
so semi-circle = 25 pi / 2
answer is a) 25 pi / 2 m^2
