Answer:
Qualitative data is information about qualities; information that can't actually be measured. Some other aspects to consider about qualitative data:
- Represented through pictures that explore the data in a visual way
- Visual representations focus on the themes found in the data
- Can also be displayed graphically as a pie chart or bar graph, the same as quantitative data, however, this can be tricky and can be done incorrectly easily
Answer:
The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates. The second example is not a function, because it contains the ordered pairs (1,2) and (1,5). These have the same first coordinate and different second coordinates.
Answer:
False
Step-by-step explanation:
False because you plug in 2 for d and makes the equation 81 + 2x2 > 90 then it`s just simple math 2x2 is 4 making it 81 + 4 > 90 and the answer is 85 > 90 which is false
Suppose you performed a regression analysis. The mse for this scenario is 0.105
Regression is a statistical method used in finance, making an investment, and different disciplines that attempt to determine the electricity and man or woman of the relationship between one established variable (commonly denoted through Y) and a sequence of different variables (called independent variables).
We are able to say that age and peak can be described through the usage of a linear regression version. because someone's peak will increase as age will increase, they have got a linear courting. Regression fashions are commonly used as statistical proof of claims regarding regular statistics.
"Regression" comes from "regress" which in turn comes from Latin "regresses" - to head returned (to something). In that feel, regression is the approach that permits "to head again" from messy, hard-to-interpret data, to a clearer and more significant version.
y ypred (y-ypred)^2
1 1.1 0.01
1.5 1.3 0.04
2.8 3.2 0.16
3.7 3.7 0
The error sum of the square is given by
ESS = (y- )
ESS=0.21
The mean square error is given by
ESS MSE = ESS/dfe
MSE = \frac{0.21}{2}
MSE = 0.105

Product factor is an expression in where you multiply the same value digit many times.
Exponent is the expression in where you convert product factor expression into a shorter expression
For example of product factor:
=> 9 x 9 x 9 x 9 x 9 x 9 x 9 x 9 x 9
As you can see, 9 is multiplied many times, that makes it longer.
Now, let’s make this product factor shorter using exponent.
=> since 9 is multiplied 9 times the exponent expression is:
=> 9 9 in where 9 is the base and the other 9 is called exponent.
