If BD = 4, AD = x-6, and CD = x, what is the length of CD?

Mathematics

8 0

Answer:

The length of CD is 8 units

Step-by-step explanation:

<u><em>The complete question in the attached figure</em></u>

we know that

According to the Right Triangle Altitude Theorem,

(BD)^2 = (AD)(CD)

substitute the given values

(4)^2 = (x-6)(x)

16=x^2-6x\\x^2-6x-16=0

solve the quadratic equation by graphing

The solution is x=8 or x=-6

see the attached figure N 2

Discard the negative length.

therefore

The length of CD is 8 units

THe chart for my last post
nydimaria [60]

Answer:

Median : 23

Mode: 11 and 24

Range: 28

Step-by-step explanation:

A stem-and- leaf plot is a very special table where each " value" is split into a stem.

Basically the stem is the foirst value of the number and the leaves are the last digits.    

<u><em>Example:</em></u> A stem of 1 and a leaf of 1 has a value of 11.

               A stem of 1 and a leaf of 2 has a value of 12.

In this case the numbers in the plot are:

11, 11, 12, 13, 14, 15, 22, 23, 24, 24, 27, 32, 35, 37, 39

The questions are :

<h3><u><em>1.</em></u> What is the median? </h3><h3><u><em>2.</em></u> What is the mode ?</h3><h3><u><em>3. </em></u>What is the range ?</h3>

To answer the first question, you need to list them in order.

Then find the center of those numbers. Cross out one number from the left and the right and keep doing it until there is only one ot two numbers.

<u><em>One number- that is the median</em></u>

<u><em>two numbers left - find the mean of the two numbers and that is the median</em></u>

So in this case the median is 23 crossing out seven numbers on each side.

To answer the second question, you need to find the number that comes up the most. In this case, 11 and 24.

To answer the third and last question, you need to find the mininum value and the maximum and find the difference.

In this case, 11 and 39, the difference is 28.
