A work survey found that 8 out of every 10 employees went on vacation last summer. If 3 employees' names are randomly chosen, with replacement, what is the probability that all 3 employees went on vacation last summer?

The result of multiplying the numbers 234 x 0.35 is 81.9

The numbers are given as:

234 and 0.35

Express the numbers in a product expression

So, we have

234 x 0.35

Express 234 as 200 + 34

So, we have

234 x 0.35 = (200 + 34) x 0.35

Expand the bracket

So, we have

234 x 0.35 = 200 x 0.35 + 34 x 0.35

Evaluate the product

So, we have

234 x 0.35 = 70 + 11.9

Evaluate the sum

So, we have

234 x 0.35 = 81.9

Hence, the result of multiplying the numbers 234 x 0.35 is 81.9

According to the Multiplication Property for Equations, an equation can be multiplied as well as divided by the exact number upon every of the equation's sides without changing the solution.

If a = b, then a/c = b/c where c is greater than zero. In other words, if two expressions are equal and subsequently multiply or divide (except for 0) the same constant by both, the two sides will remain equal.

Answer:

Step-by-step explanation:

We know that two vertical angles are equal to each other.

Then

First, We have to solve the equation 5y + 10 = 2y + 16  for y.

After that ,we can easily find the measure of the angles by substituting y by its value in their expression.

SOLVING THE EQUATION :

5y + 10 = 2y + 16

⇔ 5y - 2y = 16 - 10

⇔ 3y = 6

⇔ y = 2

Determining the measure of the angles :

angle 1 → 5(2) + 10 = 20

angle 2 → 2(2) + 16 = 20

A quadrilateral (square) may always be used to create a square in a circle. Because squares have right angles at each vertex, every pair of opposing angles in a square is complementary and inscribed in a circle. This is an unavoidable characteristic of squares.

If the form in question is a square, each pair of adjoining angles is supplementary and inscribed in a circle. This is owing to the presence of right angles at each vertex of the square. This means that the assertion can never be proven false.

To form a system with an infinite number of solutions, the equation -4x + 6y = 3 must be combined with D. 0.75 + x = 1.5 y.

A system of equations is a set of two or more equations which includes common variables.

To form a system with an infinite number of solutions, the lines should be the same or overlapping. These lines must have the same slope and y-intercept. The equations of these lines must be the multiple of one another.

Given the equation -4x + 6y = 3, rewrite this in the form c + ax = by(same as the form of the choices).

-4x + 6y = 3   ⇒   3 + 4x = 6y

To make 6y into 1.5y, divide both sides by 4.

3 + 4x = 6y   ⇒   0.75 + x = 1.5 y

Hence, the equation -4x + 6y = 3 must be combined with 0.75 + x = 1.5 y to form a system with an infinite number of solutions.

The components of the two vectors are added and subtracted to produce the addition and subtraction vector PQ. i.e. →PQ = →Q + →P and →PQ = →Q - →P

A vector, which denotes the mathematical and geometrical direction of the provided quantity, is a quantity with both magnitude and direction.

For example : Velocity, Displacement etc.  

Let's start by assuming that,

P(x,y,z) and Q(u,v,w)

Now, we need to find the vector addition and subtraction

Addition of vectors to give →PQ

→PQ = →Q + →P

= (ui + vj + wk ) + (xi + yj + zk)

= (ui + xi ) +(vj  + yj) + (wk +zk)

= (u+x) i + (v + y) j + (w + z)k

= →PQ

Similarly, Subtraction of vectors to give →PQ

→PQ = →Q - →P

= (ui + vj + wk ) - (xi + yj + zk)

= (ui + vj + wk  - xi - yj - zk)

= (ui - xi ) +(vj  - yj) + (wk -zk)

= (u-x) i + (v - y) j + (w - z)k

= →PQ

For example : Let P(1,2,1) and Q ( -1, -2,4)

Then, Addition →PQ = →Q + →P

= (1i + 2j + 1k ) + (-1i + (-2)j + 4k)

=  (1-1) i + (2 -2) j + (1 + 4)k

= oi+0j +5j

= 5j

Subtraction →PQ = →Q - →P

= (1i + 2j + 1k ) - (-1i + (-2)j + 4k)

=  (1+1) i + (2 +2) j + (1 - 4)k

= 2i+4j -3j

Hence, the vector PQ addition and subtraction is given by the addition & subtraction of the components of the two vectors.

When only three sides are provided without any information regarding the angle, such as a = 5 m and b = 9 m, c = 6m we can either create no triangle or create an unique triangle. Hence, either 0 or 1 Triangle.

For example :

How many different triangles may be formed with side lengths of 5m,9m and 6 m ?

Create a triangle with the following measurements: 5 meters, 9 meters , and 6meters, by protractor-adjusted to the given length of sides. You have constructed a triangle.

We can only create one triangle here, as no choice can be made in the given length of side as they are prefixed.

This implies that you cannot chose the side length independently. So, only one triangle which is unique will be formed. Hence, 0 or 1 triangle is formed
