Answer: OPTION B
Step-by-step explanation:
You can observe in the graph of the function given, it begins to decrease from --3π/2 to -π/2. Then it increases again to y=3, where it reaches it maximum point, this is when x=kπ/2 (With k an odd integer: 1,3,5,7...)
Finally, it begins to decrease again from π/2 to 3π/2.
Therefore, the answer is the option B.
Answer:
np = 81 , nQ = 99
Step-by-step explanation:
Given:
X - B ( n = 180 , P = 0.45 )
Find:
Sampling distribution has an approximate normal distribution
Computation:
nP & nQ ≥ 5
np = n × p
np = 180 × 0.45
np = 81
nQ = n × (1-p)
nQ = 180 × ( 1 - 0.45 )
nQ = 99
