Kara was making decorations for a school dance. She has a small figure to use for a pattern, but needs the actual
decorations to be much larger. Which scale factor might she use to make her decorations?

k = 5

Step-by-step explanation:

When a certain number is multiplied by a scale factor , the  final number is given by

and the final number will be:

- Larger than the original number if

- Smaller than the original number if

In this problem, the number represents the size of the decoration.

If we apply the 4 scale factors given, we have:

- If , then : this means that the final decoration is larger than the original decoration --> this is the correct option

- If , then : so the final decoration has same size as the original decoration

- If , then : so the final decoration is smaller than the original decoration

- If , then , so the final decoration is smaller and inverted

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

7
