What is theoretical probability of rolling a number greater than 4 on a standard number cube

1 answer:

8 0

So cube faces were numbered 1, 2, 3, 4, 5 and 6.

There are 6 faces in total and there are two faces greater than 4 (face 5 and 6).

So that would be (desired outcomes) / (total outcomes) = 2 / 6 = 1/3

So theoretical probability of rolling a number greater than 4 is 1/3.

Hope this helps.

The sum of two consecutive natural numbers is 525.<br> Find the numbers.

Luda [366]

Answer:

262 and 263 are consecutive natural numbers whose sum is 525.

Step-by-step explanation:

Natural number are a subset of real numbers consisting in positive integers (i.e. 1, 2, 3, 525) and two natural numbers are consecutive when distance between each other is equal to 1. ( $|x-y| = 1$ , $\forall\,x,y \in \mathbb{N}$ ) We can interpret the statement mathematically by means of the following expression:

$x + y = 525$

$x = n$

$y = n+1$

Where $x$ , $y$ , $n$ $\in \mathbb{N}$ .

This system is reduced to a single equation and solved afterwards:

$n +(n+1) = 525$

$2\cdot n + 1 = 525$

$2\cdot n = 524$

$n = 262$

Now we evaluate $x$ and $y$ to obtain the natural numbers:

$x = 262$

$y = 263$

262 and 263 are consecutive natural numbers whose sum is 525.

Simplify the expression. 5/8*(18*3+(-22))+(-45)

lubasha [3.4K]

Using PEMDAS
(Parenthesis)(Exponents)(Multiplication/Division)(Addition/Subtration)
So:
$\frac{5}{8} * ((54-22)-45) = \frac{5}{8}*(32-45) = \frac{5}{8}(-13)$
$= \frac{-65}{8}$ $= -8.125$

Some find slope please?

Andre45 [30]

Answer:

3/4

Step-by-step explanation:

Use slope formula y2-y1 over x2-x1

9-3=6

5--3 becomes 5+3 which equals 8

so 6/8

which when simplified is 3/4.
