It could be in inches or feet. because inches can be converted to feet, and feet can be converted to inches.

You can use feet or inches because they are both on the diagram and they are both a part of the same measuring system. If you use inches, you would be using larger numbers, but if you used feet, you would be using fractions.

I hope this helps!

Answer:

Median = 13

Step-by-step explanation:

We are given the following data:

16, 15, 13, 12, 17, 14, 11, 9, 11

Formula:

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$

Sorted data: 9, 11, 11, 12, 13, 14, 15, 16, 17

Median =

$=\dfrac{9+1}{2}^{th} = 5^{th}\text{ term} = 13$

Thus, the median of the given data is 13.

Write the range of the function using interval notation.

nalin [4]

Given:

The graph of a function.

To find:

The range of the given function using interval notation.

Solution:

Range: The set of y-values or output values are known as range.

From the given graph, it is clear that the function is defined for $0$ and the values of the functions lie between -2 and 2, where -2 is excluded and 2 is included.

Range $=\{y|-2$

The interval notation is:

Range $=(-2,2]$

Therefore, the range of the given function is (-2,2].

Which of the following tables shows the correct steps to transform x^2+6x + 8=0

Vlad1618 [11]

Perhaps the most concise way to factor is by "completing the square" which is how the quadratic formula is derived...

x^2+6x+8=0 move constant to other side, subtract 8 from both sides

x^2+6x=-8, halve the linear coefficient, square it, then add that to both sides, in this case (6/2)^2=3^2=9

x^2+6x+9=1 now the left side is a perfect square of the form

(x+3)^2=1 take the square root of both sides

x+3=±√1 subtract 3 from both sides

x=-3±√1

x=-3±1

x=-4 and -2

Since the zeros occur when x=-4 and -2 the factors of the equation are:

(x+2)(x+4)
