Answer:
D. (4, 5)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define systems</u>
y = x + 1
y = 1/2x + 3
<u>Step 2: Solve for</u><u><em> x</em></u>
- Substitute in <em>y</em>: x + 1 = 1/2x + 3
- Subtract 1/2x on both sides: 1/2x + 1 = 3
- Subtract 1 on both sides: 1/2x = 2
- Divide both sides by 1/2: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x + 1
- Substitute in <em>x</em>: y = 4 + 1
- Add: y = 5
<u>Step 4: Graph</u>
<em>We can confirm our answer.</em>
Answer:

Step-by-step Explanation:
The 44th percentile,
, of the given data can be calculated using the kth formula for percentile given as:

where,
i = the ranking or the position of the percentile = ?
k = the percentile = 44
n = total number of the given data values = 23
Plug in the values into the formula to find "i"




Since "I", 10.56, is not an integer, round the number down, and round it up to the nearest integer, then look for the position each occupy in the ordered data set, and find their average.
Thus,


The data occupying the 10th position on the data set = 28.7
11th = 31.1

Answer:
3±95√3 is simplified as 167.5495 or - 161.5495
Step-by-step explanation:
Given expression;
3±95√3
This expression can be simplified as;
3±95√3 = 3 + 95√3 or 3 - 95√3
= 3 + 95(1.7321) or 3 - 95(1.7321)
= 3 + 164.5495 or 3 - 164.5495
= 167.5495 or - 161.5495
Therefore, 3±95√3 is simplified as 167.5495 or - 161.5495
