Answer:
A. 12 + (-9)
Step-by-step explanation:
adding 8 to 4 is 12 and 9 remains as it is.
They will have the same amount of money saved in 4 days
2x + 3y = 12
I am going to put this in y = mx + b form, where m is ur slope and b is ur y intercept.
2x + 3y = 12
3y = -2x + 12
y = -2/3x + 4......slope is -2/3 and y int is (0,4)
x int can be found by subbing in 0 for y and solving for x
2x + 3y = 12
2x + 3(0) = 12
2x = 12
x = 6.....so x int is (6,0)
start at y int (0,4).....and since the slope is -2/3, come down 2 spaces, and to the right 3 spaces, then down 2 spaces, to the right 3 spaces....keep doing that and u should cross the x axis at (6,0)
Answer/Step-by-step explanation:
a. The order pair are:
(1, 6) => when x (distance) = 1, y (price) = 6
(3, 8) => when x (distance) = 3, y (price) = 8
(5, 10) => when x (distance) = 5, y (price) = 10
(7, 12) => when x (distance) = 7, y (price) = 12
{(1, 6) (3, 8), (5, 10), (7, 12)}
b. The graph represents a function because every domain value (x-value) has only one range value (y-value) that is related to each.
Answer:
Thus, the lower-2 sigma limit is 23.17
Step-by-step explanation:
We are given the following in he question:
Average complaints per month = 35
A 2-sigma control limit is used.
We have to find the lower control limit.
Putting values, we get,
Lower limit:
Thus, the lower-2 sigma limit is 23.17
