Answer:

→6²=36

→7²=49

→36 < 39 < 49

→6²< 39 < 7²

$\rightarrow 6< \sqrt{39}$

The data set shown below represents the number of times some families went out for dinner the previous week. 4, 2, 2, 0, 1, 6, 3

mestny [16]

Answer:

The correct options are:

Four families said they ate out twice the previous week.
One family said they ate out 5 times the previous week.
The median best represents the data set.

Step-by-step explanation:

We are given a data set as:

4, 2, 2, 0, 1, 6, 3, 2, 5, 1, 2, 4, 0, 1

On arranging this data set in the frequency table we get:

Number of times they went for dinner Number of families

0 2

1 3

2 4

3 1

4 2

5 1

6 1

Hence, the range of the number line is between 0 to 6.

Also there are 4 dots above 2.

Hence, Four families said they ate out twice the previous week.

Also there is one dot above 5.

Hence, One family said they ate out 5 times the previous week.

The data set is not symmetrical since the median is 2 and the data points to the left and to the right do not have symmetry.

Hence, the data set is not symmetrical.

Also we know that the median of the data is the central tendency of the data and always best represents the data.

Hence, The median best represents the data set.

You are having a conference call with theCEO of a paper company. You have interrupted the number of trees cut down verses profit

Yanka [14]

You can answer this by first attempting to simplify the polynomial to find the roots. Here I attempt to simplify it by using division.

$p(x)=-x^{4}+x^{3}+7x^{2}-x-6$
$p(x)=(x-3)(-x^{3}-2x^{2}+x+2)$
$p(x)=(x-3)(x+2)(-x^{2}+1)$

Now let us try setting p(x)=0 to compute for where the company will break even.

$p(x)=(x-3)(x+2)(-x^{2}+1)$

$x_{1} -3=0$
$x_{1}=3$

$x_{2} +2=0$
$x_{2} =-2$

$- x_{3} ^{2}+1=0$
$x_{3} ^{2}=1$
$x_{3} =1$ or $x_{3} =-1$

Now we have four roots, of which none is repeating so therefore we know that the graph will pass by the x-axis four times. The first term of the polynomial is negative and the degree is positive so the graph will start as an increasing line and it will end decreasing.

We can also quickly see that the y-intercept is (0,-6) since it is the only constant term in the function.

Knowing all these, you can tell the CEO that the graph will start at the bottom, pass by (-2,0), increase then decrease until it passes (-1,0) to which it will continue decreasing until it passes (0,-6) where it will increase until it crosses the x-axis again at (1,0) and then finally make one last increase and decrease until it passes (3,0) and then continue to decrease forever.

Since there are no negative trees to cut, you know that the company will break even when the number of trees cut is equal to 1 or 3.
