.

Answer:

This is known as Data dredging.

Step-by-step explanation:

In order for any statistical analysis to be significant, a researcher has to first generate a hypothesis.

Data dredging is trying to uncover patterns in data that can be presented statistically without devising a clear hypothesis by use data mining. It is also referred to as data fishing or p-hacking.

In this case any correlation (relationship between cause-effect)will be purely by chance.

Therefore, the investigator is Data dredging

Multiply and simplify: –3x2y2 • x4<br> –3x5y2<br><br> 9x5y2<br><br> –3x6y2<br><br> –3x5y6

Contact [7]

Answer:

Multiplying and simplifying the term $-3x^2y^2 \:.\: x^4$ we get $\mathbf{-3x^6y^2}$

Option C is correct option.

Step-by-step explanation:

We need to multiply and simplify: $-3x^2y^2 \:.\: x^4$

Simplifying the term:

$-3x^2y^2 \:.\: x^4$

While multiplying, the variables with same bases are multiplied: $a^m\:.\:a^n=a^{m+n}$

In the given question only x^2 and x^4 are variables with same bases, So we get:

$=-3(x^{2+4})y^2\\=-3x^6y^2$

So, multiplying and simplifying the term $-3x^2y^2 \:.\: x^4$ we get $\mathbf{-3x^6y^2}$

Option C is correct option.

What is the relationship between the values of the given digits 7's in 7'700

GaryK [48]

Step-by-step explanation:

The given number is 7700.

We need to find the relationship between the values of the digit 7s in it.

The digit in the extreme left is 7 and second no is again 7.

The place value of first 7 is 7000

The place value of second 7 is 700.

Taking ratio of place value of 7 in first 7 and for second 7 as follows :

$R=\dfrac{7000}{700}\\\\R=10$

So, value of first 7 is 10 times that of the value of second 7.
