Ok
First find something that will help you
($12 per hours)
(X is hours)
(Y is the money)
Next
To find y you must multiply each hours to $12.
Last:
X : 0 1 2 5
Y : ? ? ? ?
———————
X : 0(12) = 0 ( 0 hrs = $0)
1 (12) = 12 ( 1 hrs = $12)
2 (12) = 24 ( 2hrs = $24)
5(12) = 60 ( 5 hrs = $60)
Answer
0 = $0
1 = $12
2 = $24
5= $60
Equation ( I am not sure but I tried )
12x = y(total cost)
I hope this helped and was right,
Have a nice day.
Answer:
(2, - 3 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 13 → (1)
x + 2y = - 4 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = - 4 - 2y → (3)
Substitute x = - 4 - 2y into (1)
2(- 4 - 2y) - 3y = 13 ← distribute and simplify left side
- 8 - 4y - 3y = 13
- 8 - 7y = 13 ( add 8 to both sides )
- 7y = 21 ( divide both sides by - 7 )
y = - 3
Substitute y = - 3 into (3) for corresponding value of x
x = - 4 - 2(- 3) = - 4 + 6 = 2
Solution is (2, - 3 )

Answer:
14.69 seconds
Step-by-step explanation:
The weighted mean is used to calculate the mean of numbers which don't have the same "weight" or statistical relevance. In this case, that relevance is based on the sample size of each group from which the mean reaction times were obtained.
For all three samples, the weighted mean is obtaining by multiplying each one of the mean reaction times by its <em>n value, </em>adding them, and dividing that result by the sum of all n values.
