Answer:

8.8n² + 2n + 0.1

Step-by-step explanation:

For this expression, all you have to do is combine like terms, which means to combine terms with n² with each other, terms with n with each other, and so on.

7.8n² + 0.5 + 9n - 0.4 - 7n + n²

Now, put the n² terms, n terms, and constants (no n) with each other.

7.8n² + n² + 9n - 7n + 0.5 - 0.4

Now you can add and subtract to combine like terms.

7.8n² + n² + 9n - 7n + 0.5 - 0.4

8.8n² + 2n + 0.1

And that's your answer.

1. nth term=3n-1

  20th term=3(20)-1=60-1=59

2. nth term=-2n-4

   20th term=-2(20)-4=-40-4=-44

3. nth term=\frac{2}{3}n-\frac{2}{3}

   20th term=\frac{2}{3}(20)-\frac{2}{3}=\frac{40}{3}-\frac{2}{3}=\frac{38}{3}

4. nth term=-\frac{1}{3}n+\frac{11}{15}

   20th term=-\frac{1}{3}(20)+\frac{11}{15}=-\frac{20}{3}+\frac{11}{15}=-\frac{89}{15}

A frequency distribution is a tabular summary of data showing the a. number of items in several classes. b. relative percentage
Viefleur [7K]

Answer:

The answer is a: Number of items in several classes.

Step-by-step explanation:

Frequency distributions are tables that represent the number of times a specific data, number object etc appears in a sample. So for example if we have this data

2,2,4,4,6,6,6,8,8,10

The frequency distributions is

Number   frequency

2                  2

4                  2

6                  3

8                   2

10                  1

The other options are identical (c and are the same as percentages can be expressed as fractions. Relative percentages or fractions are  tables that express the weight that each category has in the entire data. An example for our data would be: (10 are the total number of obs)

Number             Fraction/%

2                          2/10 or 20%

4                         2/10 or 20%

6                          3/10 or 30%

8                           2/10 or 20%

10                            1/10 or 10%

What are these four? 3, 3, 4, and 4??
Leokris [45]

For 4. (Apples to balloons) it is really simple. All you have to do is count the amount of balloons and apples and turn into a ratio, which is a basically a fraction. The answer for that would be 4:2


For the other 4, im not sure what the answer is as i cant really see it that well.

3 and 3 are pretty easy too. All you need to do is find a common factor. For the first number 3, 6 and 8 can both be divided by 2. The will turn it in 3/4, which is as simple as the number can get. The next one can also be divided by 2, which will turn it into 5/7. Once again, this is as simple as it can get.

Answers:

3. 3/4

3. 5/7

4. ? (couldn't see it)

4. 4:2
