Answer:
B
Step-by-step explanation:
Add 3.5 to 14.9------------
6 and 10 because 6 times 10 is 60 and 6 plus 6 plus 20 plus 10 is 32
Out of 960 calculators, 8 were found be to defective
Probability:
0.00833...
As a Percent:
0.00833....× 100
0.833%
To the nearest tenth of percentage:
0.833% ≈ 0.8%
To solve the problem shown above you must apply the following proccedure:
1. You have the following function given in the problem:
<span> f(x)=x3–3x–2
2. When you give values to the x and plot each point obtained, you obtain the graph shown in the figure attached.
3. Based on the graph and analizing the alternate form:
f(x)=(x-2)(x+1)</span>²
As you can see, there is two roots x=-1, then, you can conclude that the correct answer is the option b, which is:
b) -1<span>
