Answers:
- C) 5/14
- A) 2/16
===========================================
Explanations:
- We have 5+9 = 14 people who don't have a dog. Of this total, 5 have a cat. So that's where 5/14 comes from. We ignore the top row because we know 100% that this person doesn't have a dog (based on what the "given" says).
- Focus on the top row. This is because we're given or told that the person completed the hw. We have 2 people who failed the test out of 14+2 = 16 people who did the hw. The fraction 2/16 reduces to 1/8, but it appears your teacher doesn't want you to reduce.
Answer: C.) The coefficient of determination is 0.215. 21.5% of the variation is explained by the linear correlation, and 78.5% is explained by other factors.
Step-by-step explanation:
Given that :
Number of observations = 40
Linear Correlation Coefficient (R) = 0.464
The Coefficient of determination ( R^2) =?
The Coefficient of determination (R^2) is the squared value of the linear correlation Coefficient value (R) . The value value ranges from 0 to 1 and depicts the proportion of the variation in the dependent variable that can be accounted for by the independent variable.
For the scenario given above,
The Coefficient of determination (R^2) = 0.464^2 = 0.215296 = (0.215296 * 100%) = 21.5%
This means that 21.5% of the variation can be explained by the relationship between both variables while (100% - 21.5% = 78.5%) can be explained by other factors.
P=pounds
So we have the equation 4.3p+1.7p=41.94
combine like terms and we have 6p=41.94
divide both sides by 6 and we get p=6.99
$6.99 is your answer! :D
The ranking of best beers at the Portland Brewfest in a natural and ordered manner is an example of <u>an ordinal scale.</u>
Ordinal scale of measurement is the second level of measurement that defines a variable.
Ordinal scale shows order and ranking between variables that are being defined.
The ranking of best beers is simply natural and ordered into categories. This shows magnitude and rank among variables. This makes it an example of <em>ordinal scale.</em>
Therefore, the ranking of best beers at the Portland Brewfest in a natural and ordered manner is an example of <u>an ordinal scale.</u>
