Answer:
The following tells what variable terms are and a explanation. I hope this is helpful
Step-by-step explanation:
Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables. ... In , the terms are: 5x, 3y, and 8. When a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.
Correlation coefficients are expressed by a number between -1 and 1.
If the value is -1 or 1 it indecates a perfect (negative and positive) correlation.
If the value is 0 indicates null correlation.
As the correlation value for you data set is -0.833 it is very close to the -1. It indicates a good correlation in the data. Then, the value you predicted is reasonably close to the actual value.
Answer:
-3
Step-by-step explanation:
-3x - 4 < 5
-3x < 9
x < -3
Answer:
Step-by-step explanation:
For the first one, in any triangle, we have the sum of two sides is greater than the third side. Hence, we have 3 inequalities: 
, which give us 
. We conclude that 
.
For the second question, we have 
, and similarly we can show that 
. Hence, 
.
The third question is not very clear.
