The unsorted stem-and-leaf diagram would look like this:

5 | 6, 3, 5, 0, 2

3 | 2, 7, 3, 3, 4

2 | 6, 9, 1, 1

1 | 7, 1, 1, 6, 8

4 | 4, 2, 4, 3, 4

Basically, you separate the given set of numbers by their whole number part (the digit before the decimal) and list the numbers' fractional part (digit after the decimal) in the order you see them.

The sorted diagram would then be

1 | 1, 1, 6, 7, 8

2 | 1, 1, 6, 9

3 | 2, 3, 3, 4, 7

4 | 2, 3, 4, 4, 4

5 | 0, 2, 3, 5, 6

The graph shows two lines, A and B. A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line

mixas84 [53]

( Part A: Ok 2,6 and 6,2 and 0,3 and 4.5,6 you can add 2,6 and every other number with part b which is 2,6 +0,3= 2,3 and also 2,6+4.5,6= 6.5,12 and you can do the same with 6,2 and you will get 6,5 and 10.5,8)
(Part B: 2,3^6.5,12^6,5^10.5,8)

The triangles below are similar because of the:

STALIN [3.7K]

Answer:

ΔABC and ΔXYZ are SIMILAR by SSS property of similarity.

Step-by-step explanation:

SSS Similarity Theorem:

Two triangles are said to be similar if their CORRESPONDING SIDES are proportional.

In ΔABC and ΔXYZ, if $\frac{AB}{XY} = \frac{BC}{YZ} = \frac{AC}{XZ}$ , then △ABC∼△YZX

Here, in ΔABC and ΔXYZ

AB = 9, BC = x , AC = 12

Similarly, XY = 3, YZ = 2, ZX = 4

Here,

$\frac{AB}{XY} = \frac{9}{3} = 3\\\frac{BC}{YZ} = \frac{x}{2} \\\frac{Ac}{Xz} = \frac{12}{4} = 3$

⇒ Corresponding sides are in the ratio of 3, if BC =6 units

Hence, if BC = 6 units, then the ΔABC and ΔXYZ are SIMILAR by SSS property of similarity.
