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.

For questions 13 – 15, find x so that q || r. State the converse used.
Grace [21]

Answer:

13. x = 7 ; Converse : Alternate interior angles are equal .

14.  x=12; Converse used : Linear pair

15.  x = 23; Converse: Corresponding angles are equal

Step-by-step explanation:

13.

Refer the attached figure

Given: q || r

\angle CBE =\angle DEB (Alternate interior angles )

So,  15x+3=108

15x=108-3

15x=105

x=\frac{105}{15}

x=7

So, x = 7 ; Converse : Alternate interior angles are equal .

14.

Refer the attached figure

Given q||r

\angle PQT = \angle STQ (Alternate interior angles

So,\angle PQT = \angle STQ=11x-28

Now\angle UTQ + \angle STQ = 180^{\circ}(Linear pair)

So,7x-8+11x-28=180

18x-36= 180

18x=216

x=\frac{216}{18}

x=12

So, x=12; Converse used : Linear pair

15.

Refer the attached figure

Given q||r

\angle BDC+\angle CDE = 90+2x

\angle BDE=\angle PBC(corresponding angles)

90+2x=5x+21

90-21=5x-2x

69=3x

23=x

So, x = 23; Converse: Corresponding angles are equal

An individual saves $5000 in a bank account at the beginning of each year for 10 years.
frozen [14]

Answer:

a) Amount saved if the interest is compounded annually is $5832

b) Amount saved if the interest is compounded semi-annually is $5849.5

Step-by-step explanation:

Principal Amount P = 5000

Time t = 10 years

Annual interest i = 8% = 0.08

We need to find amount saved if interest is compounded a) annually b) semi-annually

a) Amount saved if the interest is compounded annually

If interest compounded annually, n= 1

Using Formula: A=P(1+\frac{r}{n})^{nt}

Putting values:

A=P(1+\frac{r}{n})^{nt} \\A=5000(1+\frac{0.08}{1})^{1*2}\\A=5000(1+0.08)^2\\A=5000(1.08)^2\\A=5000(1.1664)\\A=5832

So, Amount saved if the interest is compounded annually is $5832

b) Amount saved if the interest is compounded semi-annually

If interest compounded semi-annually, n= 2

Using Formula: A=P(1+\frac{r}{n})^{nt}

Putting values:

A=P(1+\frac{r}{n})^{nt} \\A=5000(1+\frac{0.08}{2})^{2*2}\\A=5000(1+0.04)^4\\A=5000(1.04)^4\\A=5000(1.1699)\\A=5849.5

So, Amount saved if the interest is compounded semi-annually is $5849.5
