Answer:
Option B. y = 1.81x + 44.36
Step-by-step explanation:
The graph represents a scatter plot with a positive correlations and has a positive y-intercept.
By drawing the best line to fit the data the y-intercept will be approximately at the midpoint of 45 and 50
We will check which option is true:
A. y = 4.25 x
The equation of option A represents a line pass through the point (0,0)
Which mean y-intercept is 0 and this is wrong.
B. y = 1.81x + 44.36
According to the best line to fit the data option B is true.
Also by substitution with x = 2
y = 1.81 * 2 +44.36 = 47.98
which is near to the actual point on the graph (50)
C. y = 1.81 x ⇒ Wrong ⇒ same explanation of option A
D. y = 4.25 x + 50 ⇒ Wrong
Because the y-intercept will be approximately at the midpoint of 45 and 50
<u>So, The answer is option B. y = 1.81x + 44.36</u>
The nurse is using Deductive reasoning.
Deductive reasoning is a valid form of proof. Here, a person makes conclusions based on previously known facts. It is process of reasoning from one or more statements to reach a logically certain conclusion. If all the parameters are true and the terms are clear then the conclusion reached is necessarily true.
<h3>Answer: Net Increase of 26%</h3>
===================================================
Explanation:
If it increases by 5%, then we use the multiplier 1.05
Think of it like saying 100% + 5% = 1 + 0.05 = 1.05
Similarly, an increase of 20% means we involve 1.20
Combine those multipliers to get: 1.05*1.20 = 1.26
This is a net increase of 26%
Interestingly, we get fairly close to 25% which is what many students might go for (since 5 + 20 = 25). This is a beginner's trap.
----------------
An example:
Let's say the temperature is 20 degrees Celsius (68 degrees Fahrenheit)
An increase of 5% means it moves to 1.05*20 = 21 degrees C
A 20% increase means we go to 1.20*21 = 25.2 degrees C
The shortcut would be to do a 26% increase to get 1.26*20 = 25.2 to help confirm we have the correct combined increase.
