Answer:
(18,0)
Step-by-step explanation:
2x + 3y – 36 = 0
The x intercept is when y = 0
Solve for x
2x + 3*0 – 36 = 0
2x +0 -36 = 0
2x -36 =0
Add 36 to each side
2x-36+36 = 36
2x = 36
Divide each side by 2
2x/2 = 36/2
x = 18

Answer:
Increase by 5% ;
Remain unchanged
Step-by-step explanation:
Given that:
Raise received by all workers = 5%
Since the raise in salary cuts across all employees, then the average or mean salary will also increase by the same amount.
y = m ± c
y = new mean ; m = initial mean ; c = increase
The standard deviation on the other hand isn't affected due to change in a constant value. That is the standard deviation of a. Constant value is Zero. Hence, the standard deviation remains unchanged.
B. 3:4 = 9:12
