x in (-oo:+oo)
h/j = 15 // - 15
h/j-15 = 0
h*j^-1-15 = 0
x należy do R

Formula for the area of a circle: A = pi * r^2
A semi-circle is half of a circle. So, we will need to divide the area of the total circle by 2 to find the area of a semi-circle.
r = d / 2
r = 6 / 2 = 3
A = pi * 9
A = 9pi
Semi-circle:
A = 9pi / 2
A = 4.5 pi cm^2 or 14.14 cm^2
Hope this helps!! :)

Answer: The hypothesis test is left-tailed test.
The parameter tested here is population mean.
Step-by-step explanation:
Given : The null and alternative hypotheses are as follows:


We can see that the parameter tested here is population mean.
Also, the type of test depends on the alternative hypothesis.
Since the alternative hypothesis is left-tailed so the hypothesis test is left-tailed test.
