The time (minutes) vary directly with the number of walls and inversely to the number of people.
m = kw/p, where m = minutes, w = walls, and p = people
60 = 5k/7
420 = 5k
84 = k m = 10(84)/10
m = 84
It takes 84 minutes for 10 people to paint 10 walls.
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
This is a trick question. DFG is the isosceles right triangle so DGF=FDG=45 degrees. We have triangle DEF congruent to DGF, side-side-side. So EDG=90 degrees, so ADG=90 (they're supplementary). That's the measure of the arc AG.
Answer: 90 degrees
Answer:
10 ( 12p - 6k)
Step-by-step explanation:
4p x 3 = 12p
2k x 3 = 6k
you cannot subtract 12p and 6k bcuz they do not have the same variables.
The answer should be -4x^2+16
