The transformations that maps image onto itself are D) reflect over the y axis and then reflect again over the y axis.

Complete question

Which sequence of a transformation will result in an image that maps onto itself? A) rotate 180 degrees counterclockwise and then reflect across the x axis b) reflect over the y axis and then reflect over the x axis c) rotate 180 degrees counterclockwise and then reflect across the y axis d) reflect over the y axis and then reflect again over the y axis

Step-by-step explanation:

Reflecting a figure across the y axis then repeating the same procedure will take you to the original position. This means mapping the figure onto itself.When coordinates(x,y) are reflected on the y axis the image coordinates are (-x,y) thus repeating this will form the second image coordinates as (x,y).

The confidence interval for the difference p1 - p2 of the population proportion is (0.063, 0.329)

<h3>How to determine the confidence interval?</h3>

The given parameters are:

n₁ = 93; n₂ = 80

p₁ = 0.814; p₂ = 0.618

The critical value at 95% confidence interval is

z = ±1.96

So, we have:

$CI = (p_1 - p_2) \pm z * \sqrt{\frac{p_1(1 - p_1}{n_1} + \frac{p_2(1 - p_2)}{n_2}}$

Substitute known values in the above equation

$CI = (0.814 - 0.618) \pm 1.96 * \sqrt{\frac{0.814 * (1 - 0.814)}{93} + \frac{0.618 * (1 - 0.618)}{80}}$

Evaluate

$CI = 0.196 \pm 1.96 * \sqrt{0.001628 + 0.00295095}$

This gives

CI = 0.196 ± 0.133

Expand

CI = (0.196 - 0.133, 0.196 + 0.133)

Evaluate

CI = (0.063, 0.329)

Hence, the confidence interval is (0.063, 0.329)

Ok, 20 points for this one

arsen [322]

Answer:

Step-by-step explanation:

2 angles are added to result in = 180°

therefore

180 = 97 - 3x + 69 + 5x

180 = 166 + 2x

2x = 180 - 166

2x = 14

x = 14 ÷ 2

The value of x = 7

What is the distance between the points (2, -3) and (-6, 4) on the coordinate

VikaD [51]

Answer:

C) 10.63 units.

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the two points (2, -3) and (-6, 4). Let (2, -3) be (<em>x₁, y₁</em>) and let (-6, 4) be (<em>x₂, y₂</em>). Substitute:

$d=\sqrt{(-6-2)^2+(4-(-3))^2}$

Simplify:

$d=\sqrt{(-8)^2+(7)^2}$

Evaluate:

$d=\sqrt{64+49}=\sqrt{113}\approx10.63\text{ units}$

Our answer is C.
