If you use Desmos it'll give you these points:
  (-2,0)
  (-2,2)
  (-2,-2)
Since it's perfectly straight line, all the points with begin with -2. It's the same for graphs like y=-2, which would make them all end in -2. Hope this helped!

Answer:

The test statistic = -0.93

Step-by-step explanation:

The test statistic is given by the formula

z = (X₁ - X₂) ÷ √(σₓ₁² + σₓ₂²)

where X₁ = proportion of data of South Korean tourists = (57/134) = 0.425

X₂ = proportion of other country tourists = (72/150) = 0.48

σₓ₁ = standard error in data 1 = √[p(1-p)/n]

= √(0.425 × 0.575/134) = 0.0427

σₓ₂ = standard error in data 2 = √[p(1-p)/n]

= √(0.48 × 0.52/150) = 0.0408

z = (X₁ - X₂) ÷ √(σₓ₁² + σₓ₂²)

z = (0.425 - 0.48) ÷ √(0.0427² + 0.0408²)

z = -0.055 ÷ 0.0590586996

z = -0.9313

Hope this Helps!!!

Which of the following functions illustrates a change in amplitude?
Pachacha [2.7K]

Hey there! :)

Answer:

C.

Step-by-step explanation:

For a graph to have a change in amplitude, there must be a coefficient in front of the equation, or the 'a' value.

Recall that the transformation form of a trigonometric graph is:

y = ±a(cos(b(x-h))+k

Where 'a' is the amplitude

'b' changes the period

'h' is a horizontal shift

'k' is a vertical shift

We can look at each choice and eliminate:

A. There is only a coefficient of -1 in front of the equation, which simply results in a reflection over the x-axis. This is incorrect.

B. This equation contains a b value of 2. This changes the period of the graph, not the amplitude. This is incorrect.

C. This equation contains a coefficient, or 'a' value of -2. The amplitude is changed by a factor of 2. This is correct.

D. This graph only contains a vertical shift of 1 unit up. This is incorrect.

Therefore, C is the correct answer.
