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.
Answer:
x=wp/5
Step-by-step explanation:
20 hours because 1 mile is 1 hour so 4 miles is 4 hours so if you times the 5 days by the 4 miles/ hours you get 20 hours in 5 days.
5. they give dimes of 2 identical sides 25 & 5
25/5 = 5 so ABC is 5 times larger so 12 x 5 = 60
6. V= L x W x H/3 = 6.2 x 4.5 x 5.3 = 147.87/3 = 49.29 cubic cm
7 add both losses 3 and a half + 3 and a half = 728 and a half - 7 = 21 and a half
