You are analyzing a scatter plot that has a negative correlation. What is true of the of the x and y values?

Answers

Correlations on a scatter plot can either be positive or negative. When it has a negative correlation, it means the x values increases as the y values decreases.

There are basically two types of correlation on the scatter plot

Positive correlation
Negative correlation

A positive correlation is such that as x increases, y also increases.

However, a negative correlation is such that as x increases, y decreases.

Hence, we can conclude that the x and y values of a scatter plot with negative correlation are in opposite direction.

See attachment for a scatter plot with negative correlation.

The sum of two numbers is 38. The greater number is 5 more than twice the lesser number. What is the greater of the two numbers?

Answers

Have the first number be x and the other number be y.

Write the first equation: The sum is 38:

x+y=38

Then the second equation: x is 5 more than than 2y:

x=2y+5

Take the first equation and make it y=38-x

Then substitute it in for the 2nd equation to find x:

x=2(38-x)+5

x=76-2x+5

3x=81

x=27

Then substitute that into the 1st equation to find y:

(27)+y=38

y=11

The first number (x) is greater than the second number (y) because 27 is greater than 11

Factor the expression completely.

Help plsss

Answers

Answer:

Step-by-step explanation:

Given that,

xy^5-x⁴y

First we look for what is common, so x and y are common to both expression

So, let bring xy out

xy(y⁴-x³).
