Answer:
3
Step-by-step explanation:
<u>1) Find two corresponding lengths between the image and the pre-image</u>
Pre-image (bottom side) = 3 units
Image (bottom side) = 9 units
We can use any corresponding lengths for this step.
<u>2) Divide the length of the side from the image by the length of the side from the pre-image</u>
9 units ÷ 3 units
= 3
Therefore, the scale factor of the dilation is 3.

(Fog) = f(g(x))
g(-2)=-2+4=2
f(2)=2^2 +3 = 4+3 =7
Answer: d = 1/3
Step-by-step explanation: 48y = 48/4 = 12. So, 2d(18) is equal to 12. 12/18 is 2/3 so 2d has to equal 2/3. That means d = 1/3.
Given:
40 people
box plot data:
minimum age : 20
Q1: 28
Median: 34
Q3: 42
maximum age: 48
Q1 represents 25% of the data set.
40 x 25% = 10
There are 10 people who are aged 28 and below.
1st quartile is equal to 25% of the data set, the median is equal to 50% of the data set, 3rd quartile is equal to 75% of the data set.
4/10 would be 2/5 in simplest form.
I hope this helps! (:
