Answer: The two numbers are 151 and 66.

Step-by-step explanation: We are to find the two numbers whose sum is 217 and difference is 85.

Let, 'x' and 'y' represents the two numbers, where x > y.

Then, according to the given information, we have

$x+y=217~~~~~~~~~~~~(i)\\\\x-y=85~~~~~~~~~~~~~(ii)$

Adding equations (i) and (ii), we get

$x+x=217+85\\\\\Rightarrow 2x=302\\\\\Rightarrow x=\dfrac{302}{2}\\\\\Rightarrow x=151,$

and from equation (i), we get

$y=217-x=217-151=66.$

Therefore, x = 151 and y = 66.

Thus, the two numbers are 151 and 66.

A new operation is defined by a△b=a^2-b/b-a^2. 4△3.

dmitriy555 [2]

As the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1

As per the question statement, we are given a new mathematical operation a△b=a^2-b/b-a^2 and we are supposed to find the value of 4△3 using the same operation.

Given, a△b=a^2-b/b-a^2

now 4△3 = (4^2-3) / (3-4^2)

4△3 = (16-3) / (3-16)

4△3 = 13 / -13

4△3 = -1

Hence, as the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1.

Mathematical operation: An operator in mathematics is often a mapping or function that transforms components of one space into elements of another.

stich3 [128]

Answer-

A. strong negative correlation.

Solution-

Direction of a relationship

Positive- If one variable increases, the other tends to also increase. If one decreases, the other tends to also. It is represented by positive numbers(i.e 0 to 1).
Negative- If one variable increases, the other tends to decrease, and vice-versa. It is represented by negative numbers(i.e 0 to -1)

Strength of a relationship

Perfect Relationship- When two variables are linearly related, the correlation coefficient is either 1 or -1. They are said to be perfectly linearly related, either positively or negatively.
No relationship- When two variables have no relationship at all, their correlation is 0.

As in this case, correlation coefficient was found to be -0.91, which is negative and close to -1, so it is a strong negative correlation.
