Help me please

We can eliminate 0.6, since that would result in a smaller shape, not a larger.

If the scale factor was 2, then each coordinate for every point on the original shape would be multiplied by 2.

For example, (3,3) would become (6,6), but it didn't.  So that rules out the scale factor of 2.

If the scale factor was 1.5, then each coordinate for every point on the original shape would be multiplied by 1.5.

For example, (3,3) would become (4.5,4,5), and that checks out.  

Then (4,4) would become (6,6), and that also checks.

And (5,3) would become (7.5, 4.5), and that looks right.

Finally, (2,5) would become (3, 7.5) and that also look good.

I'd say the scale factor is 1.5.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
