Answer:
accept Null hypothesis at ∝ = 0.05
Step-by-step explanation:
To test the hypothesis that: X is b( 3, 0.3 ) ( Null hypothesis )
Let X = number of heads out of three spins
In three spins there were 4 outcomes
Ao = 0 , A1 = 1 , A2 = 2 , A2 = 3 { 0,1,2,3 } outcomes in three spins
next: lets determine the probability of each result
attached below is the detailed solution
H0 : pi = pio
where i = 0,1,2,3
Answer:
C. 33 square feet.
Step-by-step explanation:
to get the area of irregular polygon.
divide the area into two parts (see attached image)
total area = A1 + A2
where A = 1/2 base x height
total area = ( 1/2 * 6 * 8) + (1/2 * 6 * 3)
total area = 24 + 9
total area = 33 square feet.
therefore the answer is C. 33 square feet.
Answer:
Yes, f(x) = is a constant function.
Step-by-step explanation:
A function is defined to be a relation from 1 set of numbers to another set of numbers.
The main condition for a relation to be a function is that for every number in the domain there should be a <u>unique image</u>
Here the given function is f(x) =
This function is a constant function and gives the value 0.75 for all values of x.
Hence the graph would be a straight line parallel to the x-axis passing through y = 0.75.
Hence the f(x) = 0.75 is a function.
Starting from the fundamental trigonometric equation, we have
Since , we know that the angle lies in the third quadrant, where both sine and cosine are negative. So, in this specific case, we have
Plugging the numbers, we have
Now, just recall that
to deduce
