1) |x| is the absolute value function. Its vertex is at (0,0).
2) |x-1| has the same graph as does y = |x|, except that the vertex is shifted 1 unit to the left.
3) -3|x-1| has the same graph as the previous result, except that we must reflect the previous graph in the x-axis.
4) Replace the solid lines you used in this graph with dashed ones.
5) Shade the area beneath y = -3|x-1|
In summary:
the desired graph is the shaded area below the inverted v-shaped graph of
y = -3|x-1|. Its vertex is at (-1,0).
Answer:
12.5%
Step-by-step explanation:
when converting a decimal to a fraction, multiply 100.
First put the equation into standard form by isolating y:
y=-0.5x+5
To convert x to have no coefficients, the coefficient is really 1, so multiplying everything by -2 and you get
-2y=x-10
Answer:
Step-by-step explanation:
Given that a survey was conducted that asked 1004 people how many books they had read in the past year.
Results are:
x bar =12.5
s = 16.6
n = 1004
Std error of sample = 
Since population std dev is not known t critical value can be used for confidence interval.
df = 1004-1 =1003
t critical = 1.96
Margin of error 
Confidence interval lower bound 
Upper bound
