Answer:
C) 9n - 3
Step-by-step explanation:
<em>make an expression</em>
2n - 1 - (-7n + 2)
<em>open the parenthesis</em>
2n - 1 + 7n - 2
<em>combine like terms</em>
9n - 3
Sorry I don’t know the sender maybe someone else can answer
1. When determining the average change in a data set
2. When the data is skewed. You'll need to relocate your central station of data. Because the skewed data is dragging all your data away from its true typical value.(If the data is correct then the answers of mean, median, and mode should almost be identical.)
3. Determining the most common category, typically based on data points or a graph (example: transport)
Hope this helps!! :)
Given a polynomial functin
ax^2+bx+c, the highest degree is 2
given another polynomial say ax^3+bx^2+cx+d, the degree of the polynomial is 3.
From the above we can conclude that the degree of a polynomial is its highest power.
From the function given:
5+7x^9+12x-5x^7+3x^2
The highest power is 9, thus it is a polynomial of degree 9.
The coefficient of the term of degree 9 is 7.
The answer is 7.
Answer:
A
Step-by-step explanation:
Start with the 3.
You know that there is a difference of 4 between (say) 2 and 5. The 3 is a sign that the sequence is increasing. The members of the sequence are going up.
n - 1 means that the nth terms is calculated as an and uses the number of terms to be n-1. That means that the first term is a1 which is the starting point of the sequence.
The answer is an = a1 + (n-1)*d
d = 3
a1 = - 7
So let's try the formula out.
a4 = -7 + (4 - 1)*3
a4 = -7 + 3 * 3
a4 = -7 + 9
a4 = 2
Is 2 the 4th term in the series? Yes it is!
