A regression analysis between sales (in $1000) and advertising (in $) resulted in the following least squares line: Y= 32 + 8X. This implies that an increase of $1 in advertising is expected to result in an increase of $40 in sales.( why? could you help explain to me thank you so much)
Answers
Answer:
Step-by-step explanation: This is a question under linear regression analysis.
The question is trying to relate sales (in $1000) and and advertising.
Both sales and advertising are variables and are connected by the equation
Y = 32x + 8
Which is a linear regression equation of 2 variables.
Where x is the independent variable which represents advertising in this case and Y is the dependent variable which represents sales.
At $1 of adverts, we have $40 of sales.
We just simply put the fact that x = $1 (advertising) into the linear regression equation, we have the value of Y ( sales)
Y = 32(1) + 8
Y = 32 + 8
Y = $40.

Throughout the US presidential election of 2012, polls gave regular updates on the sample proportion supporting each candidate and the margin of error for the estimates. This attempt to predict the outcome of an election is a common use of polls. In each case below, the proportion of voters who intend to vote for each candidate is given as well as a margin of error for the estimates. Indicate whether we can be relatively confident that candidate A would win if the election were held at the time of the poll. (Assume the candidate who gets more than of the vote wins.)

Answer:
(0, 0) s the solution of y-4 < 3x-1 as it satisfies the inequality.
Hence, option C is true.
Step-by-step explanation:
Given the point (0, 0)
a)
Putting the point (0, 0) the inequality
y+4 < 3x-1
0+4 < 3(0)-1
4 < -1
This is false as -1 can not be greater than 4
b)
y-1 < 3x-4
Putting the point (0, 0) the inequality
0-1 < 3(0)-4
-1 < -4
This is false as -1 can not be lesser than -4
c)
y-4 < 3x-1
Putting the point (0, 0) the inequality
0-4 < 3(0)-1
-4 < -1
This is true as -4 is lesser than -1
d)
y+4 < 3x+1
Putting the point (0, 0) the inequality
0+4 < 3(0)+1
4 < 1
This is false as 4 can not be lesser than 1
Therefore, (0, 0) s the solution of y-4 < 3x-1 as it satisfies the inequality.
Hence, option C is true.

Step-by-step explanation:
The total number of miles hiked will be the sum of the numbers of miles hiked each day. Each day, the number of miles hiked can be computed by multiplying time by speed:
distance = speed × time
So, the total number of miles hiked is ...
total miles = miles on day 1 + miles on day 2 . . . . . (sum, not a difference—eliminates choice B)
total miles = (speed on day 1)×(time on day 1) + (speed on day 2)×(time on day 2) . . . . . (sum of products—eliminates choices C and D)
Choice A correctly describes the computation.
