find the scale, k, of H(3,4) if H'(9,12) after going through the transformation (x,y) ---> (kx,ky) centered at the origin

stiks02 [169]

The value of scale k is 3

Step-by-step explanation:

In order to find the scale , we can either divide the coordinates of H' by the original point or compare both the points to find the original ordered pair.

Given

H(3,4)

H'(9,12)

The coordinates of H are multiplied with some integer k to form H'

So,

For x-coordinate:

3k = 9

k = 9/3 = 3

For y-coordinate:

4k = 12

k = 12/4 = 3

Hence,

The value of scale k is 3

Answer:

Relative frequencies

Growth mind set fixed mind set Total

Attendance

every practice 0.7 0.3 1

missed at-least

one practice 0.1344 0.8656 1

Step-by-step explanation:

Growth mind set fixed mind set total

Attendance

every practice 28 12 40

missed at-least

one practice 9 58 67

Relative frequencies

Growth mind set fixed mind set Total

Attendance

every practice $\frac{28}{40} = 0.7$ $\frac{12}{40} = 0.3$ 1

missed at-least

one practice $\frac{9}{67} = 0.1344$ $\frac{58}{67} = 0.8656$ 1

Final answer:-

Relative frequencies

Growth mind set fixed mind set Total

Attendance

every practice 0.7 0.3 1

missed at-least

one practice 0.1344 0.8656 1
