Answer:
if the scatter plot has a curve like the one attached does then it is quadratic regression.
Step-by-step explanation:
Exponential growth is a specific way that a quantity may increase over time. ... Described as a function, a quantity undergoing exponential growth is an exponential function of time, that is, the variable representing time is the exponent (in contrast to other types of growth, such as quadratic growth).
Exponential growth is a specific way that a quantity may increase over time. It occurs when the instantaneous rate of change (that is, the derivative) of a quantity with respect to time is proportional to the quantity itself.
This means if it has a curve that doesn't represent same value proportions to another axis. that is different to exponential then we say it is quadratic regression.
The formal term to describe a straight line graph is linear, whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship.
Answer:
Here, x represents the weekly sale
As per the statement:
A salesperson earns $320 per week plus 8% of her weekly sales.
"8% of her weekly sales" means
then;
the expression which represents her earning =
"At least" means
then;
the sales necessary for the salesperson to earn at least $1000 in the one week
⇒
Subtract 320 from both sides we have;
Divide both sides by 0.08 we get:
Therefore, the sales necessary for the salesperson to earn at least $1000 in the one week is: greater than or equal to $8500 i.e
