Answer:

10) 10v^2-19v+6

11) 15x^3-7x^2-29x+20

Step-by-step explanation:

Well first let's make the box.

10)

Look at the image below ↓

10v^2-19v+6

11)

Look at the image below ↓

15x^3-7x^2-29x+20

<em>Thus,</em>

<em>number 10 is </em>10v^2-19v+6 <em>and number 11 is </em>15x^3-7x^2-29x+20<em>.</em>

Paul [167]

If the mean of the data set is 32.6. Then the number of pages he read in 5 days is 163.

<h3>What is Mean?</h3>

Mean is simply defined as the average of the given set of numbers. The mean is considered as one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.

Han recorded the number of pages that he read each day for five days.

If the mean of the data set is 32.6 pages. Then the total number of the pages he read till now, will be

Let the total number of the pages be x. Then we have

\rm \dfrac{x}{5} = 32.6\\\\x  \ = 5 \times 32.6 \\\\x  \ = 163

More about the mean link is given below.

Homework Progress<br> 0<br> Find the nth term of the following sequence: 4 7 12 19 28
just olya [345]

<em>Answer:</em>

n²+3

<em>Explanation:</em>

The differences between the terms are not the same, so this is not "linear". Knowing that the sequence may have started with a 1, you can try subtracting the first number with a number to get 1, and use that number to subtract the rest.

4 - 3 = 1
7 - 3 = 4
12 - 3 = 9
19 - 3 = 16
28 - 3 = 25

In this case, subtracting 3 to all the numbers gave us perfect squares! So this means the nth term has to do with squaring the number and adding three afterward! This can be checked.

√1 = 1
√4 = 2
√9 = 3
√16 = 4
√25 = 5

As we found the values of these terms by subtracting three first and then finding its square root, the nth term will be the opposite; squaring and then adding three! Again, this can be checked!

1² + 3 = 4
2² + 3 = 7
3² + 3 = 12
4² + 3 = 19
5² + 3 = 28

Hope this helps !! :D
