Brandon's ratio of total cholesterol to HDL cholesterol using the given information in its simplest form is 55 : 7
<h3>Ratio</h3>
This is the comparison between two or more quantities.
- Total cholesterol = 275 mg/dL
- HDL cholesterol = 35 mg/dL
Brandon's ratio of total cholesterol to HDL cholesterol
275 : 35
= 275 / 35
= 55 : 7
Therefore, the Brandon's ratio of total cholesterol to HDL cholesterol using the given information in its simplest form is 55 : 7

Answer:
Shirt: $45 , Tie: $12
Step-by-step explanation:
Let s be the price of the shirt
Let t be the price of the tie
Given the information from the question,
s + t = 57 - Equation 1
s - t = 33 - Equation 2
We will use substitution method to find the prices.
We will rearranging equation 1.
s = 57 - t
We will substitute s into equation 2.
57 - t - t = 33
57 - 2t = 33
-2t = 33 - 57
-2t = -24
t = -24 / -2
= 12
We now substitute t into Equation 1.
s + 12 = 57
s = 57 - 12
= 45
From here we know, the shirt costs $45 and the tie costs $12
The sample correlation coefficient r is equal to 0.9962
<span>The linear correlation coefficient is positive. -1 </span>≤ r ≤ + 1.
0.9962 is nearer to +1. Thus, the linear correlation is positive.
