Median age is the age that divides a population into two numerically equally sized groups - that is, half the people are younger than this age and half are older. It is a single index that summarizes the age distribution of a population.
The linear function that calculates the expected distance from the sun of the Voyager-2 spacecraft in x years after 1990 is given by:
y = 3.3x + 30.6.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, we have that the distance increases 33 AU each 10 years, hence the slope is given by:
m = 33/10 = 3.3.
Hence:
y = 3.3x + b.
When x = 28, y = 123, hence we use it to find b as follows:
123 = 3.3(28) + b
b = 30.6.
Hence equation to calculate the expected distance from the sun of the Voyager-2 spacecraft in x years after 1990 is given by:
y = 3.3x + 30.6.

The answer to this question is NONE OF THE ABOVE
you would take each answer and add 2 to the end of it, then factor
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.
