Yea I can help you with these problems I’ve done this a long time ago and so far I remembered how to do this. So for number 1. X=4 in this problem so we need to substitute x into 4 and recreate this expression: 4+1=5, and yes it is a solution. As for number 2, w would equal to 2 so 13-2=10 isn’t a solution because 13-12 is actually 11, so this is a false. Now number 3, v would equal to 10 so you’d have to replace 10 into this expression; so it’s going to be 2(10)=12 which isn’t a solution because 2 times 10 equals to 20. Now for number 4, p would have to equal to 7, here is the expression; 14/7=2, is a solution because if you’re going to check it do 7(2) and it would actually equal to 14 so yes it is a solution. Now for number 5 you would have to equal w to 3 so do this in an expression; 8+3=11, and yes that is a solution because you can check it as 11-3 which would equal to 8. Now for number 6 t would have to equal to 5 so replace t into 5 which the expression is going to be; 4(5)=20 so yes it is a solution because you can check it by doing 20/5=4. Now for number 7 s would have to equal to 3 so in this expression would have to be; 12/3=4 and yes that is a solution because you can check it by doing 3 times 4 which would equal to 12. Now for the last problem 8, d would have to equal to 8 so you replace d into 8 which the expression is going to be; 6+8=14, it’s not going to be 6+8=15 because it doesn’t equal to that since if you want to check the right answer just subtract 14 by 8 and you would get 6. So the last problem isn’t going to be a solution.

(a) $x^{-5}$

(b) $3x^{-7}$

Solution:

To write each of the given expression in the form $ax^n$ :

(a) $\frac{x^3}{x^8}$

Using exponential rule: $\frac{a^x}{a^y}=a^{x-y}$

$$\frac{x^3}{x^8}=x^{3-8}$

$$\frac{x^3}{x^8}=x^{-5}$

(b) $\frac{6x}{2x^8}$

Divide numerator and denominator by the common factor 2, we get

$$\frac{6x}{2x^8}=\frac{3x}{x^8}$

Using exponential rule: $\frac{a^x}{a^y}=a^{x-y}$

$$=3x^{1-8}$

$$\frac{6x}{2x^8} =3x^{-7}$

Divide numerator and denominator by the common factor 7, we get

$$\frac{28x^6}{21x^2}=\frac{4x^6}{3x^2}$

Using exponential rule: $\frac{a^x}{a^y}=a^{x-y}$

$$=\frac{4}{3}x^{6-2}$

$$\frac{28x^6}{21x^2}=\frac{4}{3}x^4$

__________ statistics consists of organizing and summarizing information collected, while (descriptive / inferential / quantita

SpyIntel [72]

Answer:

Descriptive statistic, Inferential statistic

Step-by-step explanation:

Descriptive Statistic:

The process of summarizing a data to get insight about the data.
it consist of measure of central tendency and measure of spread.
It can be about the entire population or a sample of the population.
It helps to understand the feature of the data

Inferential statistic:

It is the method of making generalizations about the entire population based on the sample.
It help us to make prediction about the population parameter with the help of sample statistic.
This is done with the help of estimation and hypothesis testing.

Thus, the correct answer is:

Descriptive statistics consists of organizing and summarizing information collected, while inferential statistics uses methods that generalize results obtained from a sample to the population and measure the reliability of the results.

Answer: 8 22 7 13 from top to bottom

Step-by-step explanation:

On the first row, the number of 2-player games is 1 meaning 2 players are playing meaning 48 are left to play the 6-player games so 8 is the number

On the second, the number of 6-player games is 1 meaning 6 players are playing meaning 44 are left to play the 2-player games so 22 is the number

On the third, the number of 2-player games is 4 meaning 8 players are playing meaning 42 are left to play the 6-player games so 7 is the number

On the fourth, the number of 6-player games is 4 meaning 24 players are playing meaning 26 are left to play the 2-player games so 13 is the number
