In the original set of numbers, the median is six
But, if six was added to the set, then the median would be six
So the median wouldn't decrease at all

The median is the middle number of all the numbers in the data set which are in numerical order.

1st put them in numerical order and close one off from each end until you get to the middle

1 3 4 5 5 7 9 9 9 9

Because there is an even number, there are two numbers so you have to take the average.

(5+7)/2 = 6

For the new number group, add 6 to the list

1 3 4 5 5 6 7 9 9 9 9

Cross one off from each side until you get the middle and the new median is also 6.

Therefore, the median did not decrease, it stayed the same.

Solve each equation by graphing the related function. If th equation has no real number solution, write no solution. X^2 + 7 = 0

Brrunno [24]

Answer:
The equation x² + 7 = 0 has no solution

Explanation:
1- using graph:
To solve the equation means graphically means to find the x-intercepts.
The attached image shows the graph of the given function.
We can note that there are no x-intercepts. This means that the given function has no real solutions

2- using algebra:
To solve the equation algebraically means to find the values of x that would make the equation equal to zero.
Solving the given equation, we would find that:
x² + 7 = 0
x² = -7
x = <span>± </span>√-7
The square root of a negative number will always give imaginary values. This means that the equation has no real solutions

Hope this helps :)

trapecia [35]

Use function notation to represent this statement:

At 1 p.m., there were 257 visitors in the museum.

Answer: V(4)=257

Explanation: It says that the Museum opens at 9 so it would be 4 hours. And the 257 is the number of visitors at that time.

Use properties of exponents to rewrite the following expressions as a number or an exponential expression with

Lerok [7]

Answer:

[(2)^√3]^√3 = 8

Step-by-step explanation:

Hi there!

Let´s write the expression:

[(2)^√3]^√3

Now, let´s write the square roots as fractional exponents (√3 = 3^1/2):

[(2)^(3^1/2)]^(3^1/2)

Let´s apply the following exponents property: (xᵃ)ᵇ = xᵃᵇ and multiply the exponents:

(2)^(3^1/2 · 3^1/2)

Apply the following property of exponents: xᵃ · xᵇ = xᵃ⁺ᵇ

(2)^(3^(1/2 + 1/2)) =2^3¹ = 2³ = 8

Then the expression can be written as:

[(2)^√3]^√3 = 8

Have a nice day!
