eight values have a mean of 7. a ninth value is added. the new mean is 9. what is the new value
Answer:
25 because the 8 values must times with 7 and will get 56. when the ninth value added , let the ninth value as y , 56+y , the new mean is 9 . so it will be like this , 56+y over 9 times with 9
Find the equation of the line that passes through the points (1, 6) and (2, 8).
By substitution in this equation, show that (3, 10) also lies on this line.
Answer:
y = 2x + 4
Step-by-step explanation:
y2 - y1/ x2- x1
= 8 - 6 / 2 - 1
= 2
So now our equation is y = 2x + b (from y = mx+b). Now plug in the coordinates to find the y-intercept.
y = 2x + b
8 = 2(2) + b
8 = 4 + b
4 = b
The y-intercept is 4.
If we put one of the values like the x in the equation, we should get the y value.
y = 2x + 4
y = 2 (3) + 4
y = 6 + 4
y = 10
(3,10)

Lead-the-market pay strategies. An employer may choose to establish an internal compensation strategy that is in excess of the pay rates in the prevailing marketplace. This compensation strategy may increase the supply of candidates, increase selection rates of qualified acpplicants, decrease employee turnover, increase morale and productivity, or prevent unionization efforts. However, prior to implementing a lead compensation strategy, an organization should carefully consider what benefits it expects to realize from such a strategy, keeping in mind that this type of structure has the greatest propensity of increasing overall labor costs.

5x + 5x = 10x
Combine like terms: 5x + 5x = 10x
10x = 10x
Add '-10x' to each side of the equation.
10x + -10x = 10x + -10x
Combine like terms: 10x + -10x = 0
0 = 10x + -10x
Combine like terms: 10x + -10x = 0
0 = 0
Step-by-step explanation:
Answer: 5x+5x=10x²
10x=10x²
10x²+ -10x²=0
10x+-10x²=0
10x(1+ -1x)=0
