How can the commutative property be used to write multiplication sentences

Mathematics

Using the commutative property means that you could do 5x4=20 and flip it around so it’s 4X5 the answer would still be 20 but in a different order

The vertices of shape K are at (4,7), (7, 7), (7,4) and (5, 5).
son4ous [18]

Answer:

To find the scale factor of the enlargement, compare the distance between a pair of corresponding points from both shapes.

<u>Shape K</u>

A = (4, 7)

B = (7, 7)

C = (7, 4)

D = (5, 5)

Horizontal distance between A (4, 7) and B (7, 7) = 3 units

<u>Shape L</u>

A' = (0, 11)

B' = (9, 11)

C' = (9, 2)

D' = (3, 5)

Horizontal distance between A' (0, 11) and B' (9, 11) = 9 units

9 ÷ 3 = 3

Therefore, Shape L is an enlargement of Shape K by scale factor 3.

To find the center of dilation (enlargement), draw two lines through 2 corresponding points (e.g. A and A',  B and B') - the point of intersection of these lines is the center of dilation.

Therefore, the center of enlargement is (6, 5)  (refer to the second attached image).

In the data set below, what is the variance?
GaryK [48]

Answer:

Step-by-step explanation:

First the mean= (1+6+7+2+9)/5=25/5=5

The Variance is taking the difference by subtracting , square it, and then average the result:

1-5=-4         -4²=16

6-5=1           1²=1

7-5=2           2²=4

2-5=-3          3²=9

9-5=4            4²=16

                    Total: 16+1+4+9+16=46

Variance= 46/5=9.2
