Answer:
if you are taking the test k12 just took it and got Minimum=24Q1=30Median=32Q3=40Maximum=42
Step-by-step explanation:
Every time you roll you have a 1/6 chance so rolling 4 times you have a 6x4= 24 and 1x4=4 so you have a 4/24 chance of getting a 6
Answer:
Option B.
Step-by-step explanation:
If the value of function is 0 at x=c, then c is a root or zero of the function. It means the graph of function intersect x-axis at its zeroes.
From the given table it is clear that the value of function are
x | f(x) | Sign
2.0 | 2.8 | Positive
2.5 | 1.1 | Positive
3.0 | –0.8 | Negative
3.5 | –1.2 | Negative
4.0 | –0.3 | Negative
4.5 | 0.7 | Positive
The sign of values of function changes in interval 2.5-3.0 and 4.0-4.5.
It means, the graph of function must intersect x-axis in interval 2.5-3.0 and 4.0-4.5. So, the zeros of the function lie between 2.5 and 3.0 and between 4.0 and 4.5.
Therefore, the correct option is B.
Answer:
<em>The minimum average cost is $2.80 when 163 players are built</em>
Step-by-step explanation:
<u>Average Cost Function</u>
<em>We'll assume the given function as the total cost to produce x players, and NOT the average cost since that is a different definition, as shown below.</em>
The cost C to produce x DVD/Blu- ray players is given by the equation
The Average Cost function is defined as
To find the extreme value of the average cost, we must take the first derivative of the function
Equating to 0
Solving for x
The second derivative is
For x=163 the second derivative is positive, thus x=163 is a minimum value. Let's compute the minimum average cost
The minimum average cost is $2.80
You would mark 2 on the number line (open circle) and draw the rest of the line going < that way.
