Answer:

The Communicative Property

Step-by-step explanation:

The <em>communicative property </em>of multiplication allow us to change the numbers' orders in a equation and still get the same product.

I hope this helps.

Answer: Commutative property of multiplication.

Step-by-step explanation:

Hi, the answer is Commutative property of multiplication.

The commutative property states that if we change the order of the numbers in the multiplication, the result does not change at all.

17 × 15.56 = 15.56 × 17

The numbers in each side of the equality are placed in opposite order, but the both sides are equal to 264.52.

Feel free to ask for more if it´s necessary or if you did not understand something.

yan [13]

5:2:1

If the shortest piece, 1, is 120cm, just multiply it by 2, then 5

120 x 2 = 240cm (the 2 in 5:2:1)
120 x 5 = 600cm (the 5 in 5:2:1)

<h2>Answer with explanation:</h2>

Given : Raymond wants to estimate the percentage of parents that use cloth diapers. He asks a randomly selected group of 200 parents whether or not they use cloth diapers.

The parameter are the number which are used to represents the quantity of a particular characteristic in entire population.

We know that to estimate the percentage of success we use the proportion of success parameter "p".

Hence, the parameter here is "p" , the proportion of parents that use cloth diapers.

Write the point-slope form of the equation of the line through the given point with the given

Marina86 [1]

Question 3)

Given

The point (1, -5)

The slope m = -5/6

Using the point-slope form of the equation of a line

$y-y_1=m\left(x-x_1\right)$

where

m is the slope of the line

(x₁, y₁) is the point

In our case:

m = -5/6

(x₁, y₁) = (1, -5)

substituting the values m = -5/6 and the point (1, -5) in the point-slope form of the equation of the line

$y-y_1=m\left(x-x_1\right)$

$y-\left(-5\right)=-\frac{5}{6}\left(x-1\right)$

$y+5=-\frac{5}{6}\left(x-1\right)$

Thus, the point-slope form of the equation of the line is:

$y+5=-\frac{5}{6}\left(x-1\right)$

Question 4)

Given

The point (-1, 5)

The slope m = -7/2

In our case:

m = -7/2

(x₁, y₁) = (-1, 5)

substituting the values m = -7/2 and the point (-1, 5) in the point-slope form of the equation of the line

$y-y_1=m\left(x-x_1\right)$

$y-5=-\frac{7}{2}\left(x-\left(-1\right)\right)$

$y-5=-\frac{7}{2}\left(x+1\right)$

Thus, the point-slope form of the equation of the line is:

$y-5=-\frac{7}{2}\left(x+1\right)$
