Of the second grade students at Hirsch Elementary, 16/20 like stuffed animals. Of the students who like stuffed animals, 4/12 prefer shaggy ones. What fraction of second grade students like shaggy stuffed animals?

4 / 15

Step-by-step explanation:

Fraction that likes stuffed animal = 16/20

4/12 of fraction who like stuffed animals prefer shaggy ones ;

Fraction of second grade that like stuffed shaggy animals ;

4/ 12 of 16/20

(4 /12) * (16 / 20)

(4 * 16) / (12 * 20)

= 64 / 240

= 4 / 15

The slope is -1

Step-by-step explanation:

Given ABC is an isosceles right triangle in which has a slope of -1 and mABC = 90°. Now, ABC is dilated by a scale factor of 1.8 with the origin as the center of dilation, resulting in the image A'B'C'.

As we know that the slope is equal to

And also in dilation only the the length of sides increases or decreases by same factor which results in same angle i.e tan remains same.

Hence, slope never changes in dilation.

Therefore, slope is -1
