Answer:
Step-by-step explanation:
You need to assume that the slope between the dependent Varian and the numerical independent variable is zero.
In regression analysis, to find the effect of one independent variable on the dependent variable, there has to be no interference from the other independent variables whether they be categorical (dummy) or numerical independent variables.
A dummy variable is one which takes on the value of 0 or 1, to represent the absence or presence (respectively) of a given category which is expected to influence the dependent variable.
When a dummy independent variable is included in a regression model, to know the effect of that dummy or category (e.g. day =1, night =0) on the dependent variable, the influence of the numerical independent variable has to be removed temporarily.
In a regression equation,
Y=a+bX+cK
Y is the dependent variable
a is the intercept on the vertical axis on the graph
b is the slope between the dependent variable Y and the independent numerical variable X
c is the slope between the dependent variable Y and the dummy variable K
Answer:
2.54 , 2 , 1/4 , -1.79 , -4
Step-by-step explanation:
Answer: 4 hours
Step-by-step explanation:
4 Hours
Explanation:
Make h = hours
You add the $55 extra cost for the assistant
$125h + $55 = $555
Use additive inverse to isolate the term with the variable
$125h + $55 - $55 = $555 - $55
Use multiplicative inverse to isolate the variable
=
Hours would be: 4 Hours.

The answer is 6/8 or 3/4. if she ate 1/4 then her family is left with 3/4. In 1/8, you multiply by 2 to get the denominator(4) to 8, you also multiply the top(3) by 2. so when you multiply it you get 6/8.
So it's a scale. On your graph, there should be units, or little squares made up of lines. For example, if you have a square that's one unit/line on each side, in real life it's going to be 2cm on each side. If you draw a square that's 4 lines/units on each side, it means that it's 8cm on each side, because that's 2cm for each little line.
