Answer: 2.5
Step-by-step explanation:
Let be the population mean .
Then, Null hypothesis :
Alternative hypothesis :
We assume that this is a normal distribution.
Given : Sample size : n=25 , since the sample is small (n<30) so we cannot apply z-test . Thus the test is t-test.
Sample mean :
Population standard deviation :
The test statistic for population mean is given by :-
i.e.
Hence, the observed critical value = 2.5
Answer:
292.45 m
Step-by-step explanation:
Both disk are at an angle of 38.48°
From the image below we calculate as,
For disk B, direct distance is 1.296 km from receiver = 1296 m
Vertical height from ground will be = 1296 x sin38.48 = 806.42 m
For disk A, direct distance is 826 m from receiver
Verival height above ground = 826 x sin38.48 = 513.97 m
Difference in height between disks is 806.42 - 513.97 = 292.45 m
Answer:
Step-by-step explanation:
We have to find the points that are on the graph by finding the order pair (x, y) We are given the x value, so substitute x in the given equation f(x) and find y.
The graph is a line
