(8x2)3 if that is meaning 8 times 2??
can be simplified to 48
The percent of markup is 20%
Step-by-step explanation:
Selling price of the drink = $1.50
Cost of the drink last year = $1.25
Percent of markup = (selling price - cost) (100)/cost
Percent of markup = (1.50 - 1.25)(100) /1.25
= 0.25(100) /1.25
= 25/1.25
= 20%
The percent of markup is 20%
Answer:
(−14.850850 ; 0.565135)
Step-by-step explanation:
Confidence interval :
Xd ± Tcritical * Sd/√n
Population 1 :30 35 23 22 28 39 21
Population 2 : 45 49 15 34 20 49 36
d = -15,-14,8,-12,8,-10,-15
The mean of d, Xd = Σx / n = - 7.14285714
The standard deviation of the difference, Sd = 10.4948967 (using calculator)
Sample size, n = 7
Tcritical at 90%, df = 7 - 1 = 6
Tcritical = 1.943176
Confidence interval :
- 7.14285714 ± 1.943176 * 10.4948967/√7
Confidence interval :
- 7.14285714 ± 7.7079925
(−14.850850 ; 0.565135)
We are given an equation d = 5h, where d is the depth of snow and h is the number of hours of a snowstorm.
We need to find the number of hours of a snowstorm that accumulate the snow to 1 centimeter.
In order to find the number of hours that accumulate the snow to 1 centimeter, we need to plug d=1 in the given equation.
On plugging d=1, we get
1= 5h.
Dividing both sides by 5, we get
1/5 = h.
<h3>Therefore, it would take 1/5 hour for 1 centimeter of snow to accumulate in Harper's yard</h3>
I am sorry I cannot solve this problem.
However, I have a tip: if you are gonna give
problems as hard as these, you might wanna offer more than just 5 points. Or you can just waste your points and get a zillion non-helpful answers like this one.
