Answer: Comparison Postulate

This is the idea that exactly one statement shown below is true

a > b

a = b

a < b

So if you compare two numbers, then either the left value is larger, the left is smaller, or the the left is the same as the value on the right.

Answer:

$\displaystyle (3, 6)$

Step-by-step explanation:

{x -4y = −21

{8y - x = 45

_________

$\displaystyle \frac{4y}{4} = \frac{24}{4} \\ \\$

$\displaystyle y = 6$ [Plug this back into both equations above to get the x-coordinate of 3]; $\displaystyle 3 = x$

the numbers 2-12 are written on cards and placed in the bag.what is the probability of picking an even number then replacing it

lorasvet [3.4K]

We have the cards numbered as 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12.

Sample number is, n(S)=11.

We pick a card and want to get even number like 2, 4, 6, 8, 10, and 12.

Probability of picking an even number would be :-

P(even numbers) = $\frac{6}{11}$

Now we replace the card and want to get a 7 in second attempt.

Probability of picking a 7 would be :-

P(number 7) = $\frac{1}{11}$

Now Probability of this event = P(even numbers) × P(number 7)

Probability = $(\frac{6}{11} )(\frac{1}{11} ) = \frac{6}{121}$

So final answer is $\frac{6}{121}$ .

2/5 of what is 2/3? i need so much help

AlladinOne [14]

The answer is 4/15

2/5 * 2/3 = 2 · 2/5 · 3 = 4/15

Multiply the numerators and denominators together. Keep the result fraction to the smallest possible denominator GCD(4, 15) = 1. It cannot further simplify the fraction result by canceling in the following intermediate step.

In other words, two fifths times two thirds equals four fifteenths.
