Which expression uses the commutative property to make it easier to evaluate

Basile [38]

Let's begin by listing out the given information:

The commutative property states that for addition, the order in which we add numbers does not change their sum & for multiplication, the order in which we multiply does not change their product.

Mathematically expressed as:

$\begin{gathered} x+y+z=y+z+x \\ x\cdot y\cdot z=y\cdot z\cdot x \end{gathered}$

Therefore, the commutative property of this is:

$\begin{gathered} \frac{4}{3}\cdot\frac{1}{5}\cdot18=\frac{4}{3}\cdot18\cdot\frac{1}{5} \\ \Rightarrow\frac{4}{3}\cdot18\cdot\frac{1}{5} \\ \end{gathered}$

Therefore, Option D is the correct answer

Suppose that Professor Rodgers needs one small group of students from his class to participate in a focus group. There are 11 st

irinina [24]

Answer:

(A) 165

(B) 330

Step-by-step explanation:

Total number of students in the class = 11

(A) How many different combinations of 3 selected students can he create?

ⁿCₓ = n! ÷ [(n - x)! x!]

n = 11, x = 3

11! / [8! 3!] = 165

<em>HINT: 8! or 8 factorial represents [8x7x6x5x4x3x2x1]</em>

(B) How many different combinations of 4 selected students can he create?

ⁿCₓ = n! ÷ [(n - x)! x!]

n = 11, x = 4

11! / [7! 4!] = 330

<em>Same hint applies here, for all numbers with the factorial sign.</em>

Find the odds for and the odds against the event rolling a fair die and getting a 1, a 4,or a 5

slega [8]

Answer:

Odds for = Odds against = 1/2

Step-by-step explanation:

In a fair die, we have {1, 2, 3, 4, 5, 6} and $n(S) = 6$

{1, 4, 5} and {2, 3, 6} constitute the entire sample space.

So, Probability of getting a 1 or a 4 or a 5

= Probability of getting a 1 +

Probability of getting a 4 +

Probability of getting a 5

= $\frac{1}{6} + \frac{1}{6} + \frac{1}{6}$

= $\frac{3}{6} = \frac{1}{2}$

Therefore, Odds for 1 or 4 or 5 = $\frac{1}{2}$ .

Since, Probability of getting a number between 1 and 6 is 1 and Probability of getting a number from 2 or 3 or 6 = $\frac{1}{2}$ , we have:

Probability of not getting a 1 or 4 or 5 = 1 - $\frac{1}{2}$

= $\frac{1}{2}$

Hence, odds for and odds against = $\frac{1}{2}$

Answer:

(-4,2)

Step-by-step explanation:

Just had the test for this thing lol.

so what you do is find the point Y.

then subtract 1 from it's x axis then add 2 to it's y axis.

work

before: (-3,0)

-1. +2

after. (-4,2)

hope this helps!
