ValentinkaMS [17]

9514 1404 393

Answer:

D'(2, -1)

Step-by-step explanation:

Dilation about the origin by factor k multiplies each coordinate by that factor:

(x, y) ⇒ (kx, ky)

For k = 1/3, this is ...

(x, y) ⇒ (x/3, y/3)

D(6, -3) ⇒ D'(6/3, -3/3) = D'(2, -1)

The table below shows the preferences of 86 members of the national honor society at Mosley high school

Otrada [13]

Prefers sports = 37
Prefers movies = 28
Total students = 86
We will calculate the percentage for each case:
sports:
N = (37/86) * (100) = 43.02%
movies:
N = (28/86) * (100) = 32.56%
Therefore, the highest percentage is found in students who prefer sports.
Answer:
No, the percentage of students who prefer sports is higher than the percentage of students who prefer movies
