1st choice: If the flower is a rose (total rose = 105), there are 45 yellow ones, so P(yellow|rose) = 45/105 = 3/7. P(yellow) = total yellow / total = 135 / 315 = 3/7. Therefore, these are equal, and this statement is not true.
2nd choice: P(hibiscus|red) = red hibiscus / red = 80 / 120 = 2/3. P(hibiscus) = hibiscus / total = 210 / 315 = 2/3. This is true.
Therefore the second statement is true.

A square has side length 3.4 cm. The side length of the enlargement is 17 cm. Determine the scale factor.
lora16 [44]

Answer:

The scale factor is <u>5</u>

Step-by-step explanation:

To find the scale factor, we divide 17 by 3.4 to find how much it was enlarged by.

17/3.4 = 5

We do this becuase when finding the scale factor, we take the dilated shape/side length and divide it by the original shape/side length.

Describe how you know that (8+9)+3 is equivalent to 8+(9+3). What is the benefit to using this property
NISA [10]

Answer:

Associative property of addition

Step-by-step explanation:

The associative property of addition is as follows :

a+(b+c) = (a+b)+c

We have,

a = 8, b = 9 and c = 3

So,

Using above property,

(8+9)+3 = 8+(9+3)

20 = 20

Hence, this is the required solution.
