In the first reaction, Gold (Au) gets 3 electrons and became Gold. In the second reaction, Iodine (I) loses 2 electrons and became Iodine.

<h3>What are cations and anions?</h3>

When the atom loses the election then it is called a cation and when it gains the electron is called an anion.

Two reactions are given.

First reaction;

Au³⁺ + 3e⁻ ⇒ Au

In the first reaction, Gold (Au) gets 3 electrons and became Gold.

Second reaction;

2I⁻ ⇒ I₂ + 2e⁻

In the second reaction, Iodine (I) loses 2 electrons and became Iodine.

More about the cation and the anion link is given below.

The solution to an inequality is (–∞, 6.5]. Is 6.5 a solution to the inequality? Explain your answer. The solution includes numb
Korvikt [17]

Answer:

Because a bracket is used, the solution includes 6.5

The solution includes numbers from negative infinity to 6.5

Step-by-step explanation:

we know that

If the solution for an inequality is (–∞, 6.5]

then

x\leq 6.5

The solution is all real numbers less than or equal to 6.5

so

Because a bracket is used, the solution includes 6.5

The solution includes numbers from negative infinity to 6.5

The average age of online consumers a few years ago was 24.1 years. As older individuals gain confidence with the​ Internet, it
love history [14]

Answer:

The correct option is (C).

Step-by-step explanation:

A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.  

It is a hypothesis of no difference.

It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.

Whereas the alternative hypothesis is a contradicting statement tot he null hypothesis. It is denoted by Hₐ.

In this case we need to test whether the average age of online consumers has increased or not.

From previous data we know that the average age of online consumers a few years ago was 24.1 years.

A one-sample mean test can be used to determine whether the mean age has increased or not.

The hypothesis for the test can be defined as follows:

<em>H₀</em>: The average age of online consumers is 24.1 years, i.e. <em>μ</em> = 24.1.

<em>Hₐ</em>: The average age of online consumers is more than 24.1 years, i.e. <em>μ</em> > 24.1.

Thus, the correct option is (C).

find the minimum value of p=10x+26y the constraints are x+y less than or equal to 6, 5x+y greater than or equal to 10, x+5y grea
bagirrra123 [75]

Answer:

Minimum value of p=10x+26y is 80 at (1.5,2.5)

Step-by-step explanation:

We are given

The objective function is, Minimize p=10x+26y

With the constraints as,

x+y\leq 6\\5x+y\geq 10\\x+5y\geq 14

So, upon plotting the constraints, we see that,

The boundary points of the solution region are,

(1,5), (1.5,2.5) and (4,2).

So, the minimum values at these points are,

Points                              p=10x+26y    

(1,5)                                  p=10x\times 1+26\times 5         i.e. p = 140

(1.5,2.5)                            p=10\times 1.5+26\times 2.5    i.e. p= 80

(4,2)                                 p=10\times 4+26\times 2          i.e. p = 92

Thus, the minimum value of p=10x+26y is 80 at (1.5,2.5).
