Answer:

D. √27 +3>17/2

Step-by-step explanation:

The square root of 27 is 5.196, added by 3 equals 8.196.

But 17/2 as a decimal equals 8.5, 8.196 > 8.5 is not true.

Consider the set of whole numbers from 1 to 10. List the numbers that meet the condition: less than six or even

choli [55]

Answer:

1, 2, 3, 4, 5, 6, 8, 10

Step-by-step explanation:

The important point in the condition is the or, meaning either the number must less than six or the number must be even. Even if both the condititons are met it, will be acceptable but not necessary.

The set of numbers we are working with : {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Out of these, numbers less than six : {1, 2, 3, 4, 5}

and the even numbers (divisible by 2) are : {2, 4, 6, 8, 10}

So the required list of numbers (removing doubles) : {1, 2, 3, 4, 5, 6, 7, 10}

How to write all real numbers in set notation?

laila [671]

Hi, this is the notation for inclusion of all real numbers.

$x \in \mathbb{R}$

We can also state numbers which are positive or negative with a sign on top of the R notation like so:

$x \in \mathbb{R}^{+} \text{ or } x \in \mathbb{R}^{-}$
