Answer:
multiply the percent
20%=0.2
130x0.2=26
26 copies were already made
130-26=104
104 more copies need to be made
Step-by-step explanation:
Answer:
a=4m
b=63x¹2 - 35x6 maybe you formatted/typed this wrong, but this is impossible..?
c=4
Answer:
a)D. Since the company wants to predict revenue from advertising expenditure, the explanatory variable is advertising expenditure.
b)B. Since the company wants to predict revenue from advertising expenditure, the response variable is revenue
c)C. Since advertising expenditure is the explanatory variable, it should be plotted on the x-axis.
Step-by-step explanation:
a) The explanatory variable is the independent variable (the difference between explanatory an indepent is that independent means that it doesn´t depend of any variable at all and in the explanatory variable we are not 100% sure)
In this case, the company wants to know if the money they spend in advertising is related to the company's revenue. So , in this case the explanatory variablle is the money they spend in advetirsing while the dependent variable is the revenue ( that will increase or decrease depending on the money spent)
b) The response variable ist he dependent variable so like it was explained in a) is revenue.
c) In a cartesian graphic on the x axis we always draw the independent variable, so in this case we will draw the money spent in advertising.
<u>ANSWER</u>
<u>EXPLANATION</u>
We have
.
Expressing in terms of means we should rewrite the relation such that will remain on one side of the equation while and any other constant will be at the other side.
To make the subject, we add to both sides of the equation.
.
we now multiply the whole equation by the reciprocal of the coefficient of , which is .
This implies that;
This simplifies to;
Answer:
False
Step-by-step explanation:
Given a line with slope m then the slope of a line perpendicular to it is
= -
Given a line with m =
Then the slope of the line perpendicular to it is
= - = -
