Answer:
A. Assuming that the mean weights of wolves in the populations are equal, the probability of obtaining a test statistic that is greater than 2.771 or less than −2.771 is 0.01.
Step-by-step explanation:
Answer: 20.71 m
Step-by-step explanation:
Given
the length of the poles are 25m and 35 m
The length of the cable is 23 m
Suppose the distance between them is x
From the figure, apply Pythagoras theorem
Distance between Poles is 20.71 m
Answer:
D
Step-by-step explanation:
Let's start by crossing everything out!
12/3 can be crossed out to 4.
a^3/a^2 can be crossed out to a.
b^6/b^4 can be crossed out into b^2.
c^5/c^5 is just 1.
So which the results we got, we can multiply them, so that it is 4ab^2.
4ab^2 is our final answer!
Answer:
we have the expression as;
1/sin u cos u
Step-by-step explanation:
tan u = sin u/cos u
cot u = cos u/sin u
Thus;
sin u/cos u + cos u/sin u
The lcm is sin u cos u
Thus, we have that;
(sin^2 u + cos^2 u)/sin u cos u
But ; sin^2 u + cos^2 u = 1
so we have ;
1/sin u cos u
