Answer:
Depreciation rate = 16.32%
Step-by-step explanation:
First we calculate the annual depreciation of the car
Annual Depreciation = (Cost of car – Net Scrap Value of car)/Useful Life
Details
Cost of Car= $14850
Net scrap Value of car= $3,960
useful Life=4
Thus: Annual Depreciation = ($14850-$3,960)/4
= $2,722/year (Annual Depreciation)
Rate = Annual Depreciation/Cost of car X 100%
= $2,722/$14,850 X 100%
Depreciation rate = 16.32%
Answer:
The answer is x = 25%
Step-by-step explanation:
84 represents 100% of the questions.
63 represents x% of the correct answers.
x = (63x100)/84
x = 6300/84
x = 75% correct answers.
percentage of the wrong answers:
100% - 75% = 25%
Answer:
a)
The sample is 60 rewards members for the makeup company
b)
Appropriate population is the entire members of the makeup company
c)
(Email showing new products or emails showing products that were on sale) are the predictor variables and its categorical
d)
the recipient clicked through to the website or not; is the response variable and its also categorical
Step-by-step explanation:
Given the data in the question;
a) What is the sample?
The sample is 60 rewards members for the makeup company
b) What would be an appropriate population to draw inference to based on this sample?
Appropriate population is the entire members of the makeup company.
c) What is the predictor variable? Is it quantitative or categorical?
The predictor variable is type of emails i.e (email showing new products or emails showing products that were on sale).
This categorical.
d) What is the response variable? Is it quantitative or categorical?
The response variable is; the recipient clicked through to the website or not.
This is also categorical.
Answer:
It should be 245 m
Step-by-step explanation:
Separate it like this:
chop of the rectangle part and find the area of that and then add it to the trapezoid part
10*20 = 200.
Area of a trapezoid = 5+10/2 *6.
5+10 = 15. 1
5/2 = 7.5.
7.5*6 = 45.
45 + 200 = 245
The other answer here, by Nicholasrichar, has the correct answers,
but it's a pain to follow through step-by-step because of the formatting
problem. Here's my solution, leading to the same answers:
P = cost of pancakes
cost of omeletto, = P+1.50
4 omelettes = 4P + 6
3 pancakes = 3P
Total cost of food = 7P + 6
After 7% tax = 1.07(7P + 6)
After tip = 1.07(7P + 6) + 3.50
Eliminate parentheses: 1.07(7P) + 1.07(6) + 3.50 =
7.49P + 6.42 + 3.50 =
Total cost of breakfast: 7.49P + 9.92 .
Having a "range" between $25 and $40 is really two inequalities:
First inequality: $25 < 7.49P + 9.92
Subtract 9.92 from each side: 15.08 < 7.49P
Divide each side by 7.49: $2.013 < P
An order of pancakes costs more than $2.01 .
Second inequality: 7.49P + 9.92 < $40
Subtract 9.92 from each side: 7.49P < 30.08
Divide each side by 7.49 : P < $4.016
An order of pancakes costs less than $4.02.
The price range of an order of pancakes is $2.01 < Pancakes < $4.02 .
