Answer:
7.41, 7.6, 745
Step-by-step explanation:
Okay, i don't want to give you the direct answer because i want you to know how to do it ... First you multuply $4.30 x .4 and you will get a number... remember that number in your head and subtract it from the original amount of $4.30... then once you get the number from subtracting the discount, multiply that number by .6..... then with that number, add the sales tax and there is your answer!
Substitution
Step 1: Solve for x or y in either of the two equations. In the equations that you are given, y is already solved for you.
Step 2: Plug in 2x + 6 into the opposite equation.
2x + 6 = -3x + 16
- 6 - 6
------------------------------
2x = -3x + 10
+ 3x + 3x
------------------------------
5x = 10
------ ------
5 5
x = 2
Step 3: Plug in the x value into either equation.
y = 2(2) + 6
y = 4 + 6
y = 10
The final answer gets expressed as a coordinate pair: (x,y) (2,10)
I hope this helps you :)
Answer:
I believe its because it going agents the wind
The frequency of A's would be 16.
The following would be the relative frequencies after the initial .08.
.18, .45, .15, .14.
To find the frequency of A, start by subtracting all of the other values from the total number. There are 200 total students, so subtract the other grade ranges.
200 - 36 - 90 - 30 - 28 = 16.
Now to find all of the frequencies, just divide each value by the total (200).
36/200 - .18
90/200 = .45
30/200 = .15
28/200 = .14
