Answer:
a) response variable
Step-by-step explanation:
The response variable is the variable that depends on other variables such as the independent or explanatory variable, it is the variable that is being tested. The response variable is also called the dependent variable.
In linear regression, the y variable is referred to as the response variable while the x variable is referred to as the explanatory or independent variable.
In this case the y variable is "the number of times they cough in a day" and this variation depends on the x variable "number of cigarettes a person smokes in a day".
Answer:
see explanation
Step-by-step explanation:
For a given scale factor k
If k > 1 then expansion
If k < - 1 then expansion in the opposite direction
If 0 < k < 1 or - 1 < k < 0 then contraction
k = - 2 ← expansion in opposite direction
k = 1.5 ← expansion
k =
← contraction
k = -
← contraction
Answer:1.85+x=5.30
Step-by-step explanation: ez
Answer
The difference is -5
Because
In the number line
-3 is in the negative side and
2 is in the positive side
So difference means minus
So,
-3-2
=-5
Remember
- - = + (but the answer should have - sign)
- + = - (the greatest number's sign will be taken)
++ = -
+ - = -
