What are the period and amplitude of the function?A) period 3, amplitude 1.5
B) period 3, amplitude 3
C) period 4, amplitude 1.5
D) period 4, amplitude 3

Answers

Answer 1

Answer:

Answer:

Option: A is the correct answer.

A) Period: 3 , amplitude : 1.5

Step-by-step explanation:

We know that Period of a function is the smallest value such that the function repeats after a fixed time.

and also the amplitude of the function is the height above or below the mid-line.

After looking at the graph we see that the period of the function is: 3

Since the function is repeating itself after every x=3.

Also, the mid-line of the function is: y= -0.5.

Hence, the height above the mid-line is: 1+0.5 = 1.5

Hence, amplitude= 1.5

Answer 2

Answer: period 3, amplitude 1.5

What is the unitary method?

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given here, the baby's weight as 6.6 lbs and 1 lb=0.45 kg

Thus 6.6 lbs=6.6×0.45

= 3.0 ( approx)

Hence, The correct weight of the baby is given by option B) 3.0 kg

/_A and /_B are vertical angles. If m_A = (2x – 4) and mZB = (x + 1)º,then find the value of x.

Answers

1. Set each equation to each other. 2x-4=x+1
2. Subtract x from 2x. 2x-x-4=x-x+1
3. Add 4 to both sides. x-4+4=1+4
4. Answer to value of x=5.

To determine whether voters would be willing to vote for a tax increase to improve the city's schools, the board of education surveys 500 parents of children in the city's schools. Why is this sample likely to be biased?

A.The entire population of the city was not surveyed.

B.Parents of school children are too busy to be bothered with surveys.

C.There are not enough people in the sample.

D.Parents of school children are more likely to be willing to pay more to improve schools.

Answers

B.

This is because, the people who conduct the survey and came to the conclusion of B are making an assumption that they are too busy. This is biased because from the point of view of THEM or even the education board, this could be manipulated in such a way that is not factual.

So in a nutshell, B is bias because it is not 100% factual. Remember, it's all about perspective.
