Orígenes de los números naturales

nikdorinn [45]

The natural numbers are presumed to have started before recorded history when humans began to count things. The Babylonians developed a place-value system based on the numerals for 1 (one) and 10 (ten). The ancient Egyptians added to this system to include all the powers of 10 up to one million.

When rolling two six-sided number cubes, what is the probability of getting a sum of at least 5? 5/18 1/3 13/18 5/6

VashaNatasha [74]

The sample space for two six sided cubes =

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

Now the favourable events are those where the sum is greater than or equal to 5.

It means

(1,4) (1,5) (1,6)

(2,3) (2,4) (2,5) (2,6)

(3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

It means

favourable events = 30

and total possible events = 36

So probability = 30/36 = 5/6

Hence 4th option is the correct one.

Which of the following could be an example of a function with a range (-∞,a] and a domain [b, ∞) where a < 0 and b < 0?

aleksandrvk [35]

Answer:

$f(x) = - \sqrt{x - b} + a$

Step-by-step explanation:

We have to choose the function from the given options which have a range (-∞, a] and a domain [b,∞) where a < 0 and b < 0.

I think the function is $f(x) = - \sqrt{x - b} + a$ ......... (1)

Here, x - b must be greater than equal to zero for the function to be real.

Hence, x - b ≥ 0

⇒ x ≥ b

So, the domain is [b, ∞).

Now, putting x = b in the equation (1),we get f(x) = a and putting x = ∞, we get f(x) = - ∞.

Therefore, the range of the function is (-∞, a]. (Answer)

What is the relationship between a linear pair and supplementary angles

lidiya [134]

Answer:

Relationship between a linear pair and supplementary angles is " If two angles form a linear pair then they are supplementary."

Step-by-step explanation:

Supplementary angles are two angles whose sum is 180°.

Linear pair is a pair of two angles that forms a straight line.

We have to find the relationship between a linear pair and supplementary angles.

Since A linear pair forms a straight line so angle formed at any point on the straight line is 180°, thus forms supplementary angles.

Thus, Relationship between a linear pair and supplementary angles is " If two angles form a linear pair then they are supplementary."
