Answer:

-5x/2 = 10

x = -4

Step-by-step explanation:

Let the unknown number be represented as x.

Negation of the product of five times the number is - 5x

Negation of the product of five times a number divided by two is ten.

Expressing this in equation format:

-5x/2 = 10

=> x = -(10 * 2)/5 = -20/5 = -4

Hence the unknown number is -4.

Validation:

-5 * (-4) / 2 = 20/2 = 10

The given equality is satisfied when the value of unknown variable x = -4

Answer:

-(5*-4)/2 = 10

Step-by-step explanation:

The product of 5*-4 = -20

-20/2 =-10

This product itself is negative (the but outside the parentesis there is a negative sign (the negation of this product) (-,- =+)

-(5*-4)/2 = 10

The total length of the segment AD will be 52 units.

The complete question is given below:-

The figure shows segment A D with two points B and C on it in order from left to right. The length of segment A B is 22 units, the length of segment BC is 19 units, and the length of segment C D is 11 units. What will be the total length of the segment AD?

<h3>What is the length?</h3>

The measure of the size of any object or the distance between the two endpoints will be termed the length. In the question the total length is AD.

Given that:-

Segment AD with two points B and C on it in order from left to right.
The length of segment AB is 22 units, the length of segment BC is 19 units, and the length of segment C D is 11 units.

The total length will be calculated as:-

The total length will be equal to the sum of all the segments of line AD. It will be the sum of AB, BC and CD.

AD = AB + BC + CD

AD = 22 + 19 + 11

AD = 52 units

Therefore the total length of the segment AD will be 52 units.

A random variable x takes four possible values, 0, 2, a, and b, where a and b are unknown numbers. if pr[x = 0] = 0.2, pr[x=2] =

Alexus [3.1K]

$\displaystyle\sum_{x\in\{0,2,a,b\}}\mathbb P(X=x)=1$
$\mathbb P(X=0)+\mathbb P(X=2)+\mathbb P(X=a)+\mathbb P(X=b)=1$
$0.2+0.4+0.3+\mathbb P(X=b)=1$
$\implies\mathbb P(X=b)=0.1$

$\mathbb E(X)=\displaystyle\sum_{x\in\{0,2,a,b\}}x\mathbb P(X=x)=2.8$
$0\mathbb P(X=0)+2\mathbb P(X=2)+a\mathbb P(X=a)+b\mathbb P(X=b)=2.8$
$0.8+0.3a+0.1b=2.8$
$0.3a+0.1b=2$

$a+b=6\implies0.3a+0.1b=0.2a+0.1(6)=2$
$0.2a+0.6=2\implies0.2a=1.4\implies a=7$
