Answer:
The graph in the attached figure
Step-by-step explanation:
we have
1)
-----> For the interval (-∞,-1)
Note The value of x=-1 is a open circle ( is not included)
This is a vertical parabola open upward
The vertex is a minimum
The vertex is the point (-2,0)
2)
----> For the interval [-1,1]
Note The value of x=-1 and x=1 are closed circle ( both values are included)
This is an absolute function open upward
The vertex is the point (0,1)
3)
-----> For the interval (1,∞)
Note The value of x=1 is a open circle ( is not included)
The value of f(x) is negative for all values of x
therefore
The graph in the attached figure
Answer:
<h2>-7</h2>
Step-by-step explanation:

22% is 0.22 in decimal form
0.22×45= $9.90 markdown so 45-9.90= $35.10 is the sales price
Answer:
40%
Step-by-step explanation:
Subtract 1,400 by 1,000 then divide by 1,000
Number employees N = 600
Then
Probability of Single + College degree = ?
Probability of single S = 100/600 = 1/6
Probability of College graduate G = 400/600 = 2/3
So then probability of both S and G is
Prob Single or Graduate = 1/6 + 2/3 = 1/6 + 4/6 = 5/6
. = 0.833
Then answer is
Probability of Single or Graduate = 5/6= 0.8333
Is also 83.33%
