Answer:
The answer is B
Step-by-step explanation:
Answer:
option A
Step-by-step explanation:
To Test
H₀ : μ = 3.75
H₁ : μ ≠ 3.75
now,
If μ = 3.95 then it means H₀ is not true.
then the probability is rejecting the null hypothesis.
Hence, the probability is the power of the test against the alternative μ=3.95
The correct answer is option A
Answer:
b = -9
Step-by-step explanation:
The function is given as :

The axis of symmetry for this function is x = 3/2
It is required to find the value of b. The axis of symmetry of a parabola is a vertical line that intercepts its vertex at its horizontal coordinate. It can be given by :

Putting x = 3/2 and a = 3 we get :

So, the value of b is -9.
Left to right because in order of operations PEMDAS, The multiplication and division it's which one is first (which is which one is on the left)
