Answer:

Mean:7 Median:6

Step-by-step explanation:

Okay so the Median is 6, and the mean is correct.

Median:

3, 3, 5, <u>6,</u> 6, 10, 16.

Your median is 6.

Mean:

Yes, your mean is 7.

Example:

I will put an example on median and mode below this so you can see how you were right and how I got the median.

Step-by-step explanation:

                                                    MEAN

First, add all the values together and divide by the number of values in the set. Imagine 3 people donated money to red cross. Their names are Allisa, John, and Thomas. Allisa gave 20 dollars, John gave 35, and Thomas gave 20. Next, you add the amount of money they donated, which is 70. Then you divide 70, the amount of money, by 3, because thats the amount of people that donated. Then you get a mean of 23.

To put it simpler,

add the values.

then, add the amount of whatever carries that value, such as people.

after, you devide the value and the amount of people or etc.

when you finish, your mean will be what you have divided.

Another example would be this.

There are several whales out in the ocean. One is the Cuvier's beaked whales, which can swim as deep as 2,992 m. Another whale, named the sperm whale, can swim down to at least  1,000 m.

So, what is the mean?

Once again, first, we add the value, which in this case, is how deep the whales can dive. We then get 3992 m.

Next, we add the amount of whatever carries that value, which in this case are whales.

after, you devide the value by the amount of whales.

when you finish, you will get 1996

                                                    MEDIAN

Arrange your numbers in numerical order. If they were scrambled like this, 9, 7, 3, 9, 6, 1, 5, rearrange them like this. 1, 3, 5, 6, 7, 9, 9.  

When you do this, check how many numbers are in that row. In this case, the amount is 7, which is odd.

If you have an odd number like in the example above, select the number in the middle, which in our case, its 6. ( 1, 3, 5, 6, 7, 9, 9 )  So your median would be six, since median means "the middle number"

If you have an even number, add them together then divide by 2. Heres an example. 1, 3, 5, 6, 7, 9, 9. (1, 3, 5, 8, 12, 9, 9, 12) You would add 8 and 12. Your answer would be 20. So now, you divide 20 by 2. 20 divided by 2 is 10, so your median would be 10.

I did not plagerise this, I made these example up myself and solved them the way they are supposed to be and used these examples on another question similar to this.

in a AP the first term is 8,nth term is 33 and sum to first n terms is 123.Find n and common difference​
allsm [11]

I believe there is no such AP...

Recursively, this sequence is supposed to be given by

\begin{cases}a_1=8\\a_k=a_{k-1}+d&\text{for }k>1\end{cases}

so that

a_k=a_{k-1}+d=a_{k-2}+2d=\cdots=a_1+(k-1)d

a_n=a_1+(n-1)d

33=8+(n-1)d

21=(n-1)d

n has to be an integer, which means there are 4 possible cases.

Case 1: n-1=1 and d=21. But

\displaystyle\sum_{k=1}^2(8+21(k-1))=37\neq123

Case 2: n-1=21 and d=1. But

\displaystyle\sum_{k=1}^{22}(8+1(k-1))=407\neq123

Case 3: n-1=3 and d=7. But

\displaystyle\sum_{k=1}^4(8+7(k-1))=74\neq123

Case 4: n-1=7 and d=3. But

\displaystyle\sum_{k=1}^8(8+3(k-1))=148\neq123

PLZZZZ HELPP WILL GIVE BRAINLIEST
liberstina [14]

Answer:

HL

Step-by-step explanation:

Since both triangles are right angle triangles that means one angle is 90°. other two sides are given congruent .

that means lengths of hypotenuse and the leg of the one right angle triangle is equal to the corresponding other hypotenuse and leg of other triangle.

This fulfills the condition of HL congruency.

Determine how many zeros, how many real or complex, and find the roots for f(x) = x3 − 5x2 − 25x + 125.
miskamm [114]
We can write this as:-

P(x) = + x^3 - 5x^2 - 25x + 125
There are 2 changes of real sign so by Descartes Rule of  signs there are either 2  positive real roots or 0 positive roots.

P(-x)  = - x^3 - 5x^2 + 25x + 125 
There is just one change of sign  so  there is exactly 1 real negative root.

125 is a multiple of 5 so By rational root theorem  5 could be  a positive root.

P(5) =  125 - 125 - 125 + 125  = 0   so one zero is  5
if we divide   the polynomial by (x - 5) we get the quadratic
x^2 - 25 
(x + 5)(x - 5) = 0

x = 5,-5

so the roots are 5 (multiplicity 2)  and -5.
2 real positive zeroes  and one real negative zero
