The given graph shows the cost for renting a post hole digger from a local hardware store. We have to determine the rate of change or cost per day.
Let us consider any two points.
Let us consider (1,30) and (2,60)
We have to determine the rate of change which is basically termed as "slope".
Rate of change is expressed as a ratio between a change in one variable relative to a corresponding change in another variable.
Therefore, rate of change or cost per day =
Change in y 
Change in x
= 
= 30
Therefore, the rate of change or cost per day is $30 per day.
Answer:
a) numerical discrete, b) categorical, c) numerical continuous, d) numerical continuous, e) categorical
Step-by-step explanation:
Categorical variables are those that represent attributes. For example, the colors of a model of car. It could be black, white, or red. It represents an attribute that can’ t be measured, only can be classified. Categorical variables can be classified into two types: nominal and ordinal. The categorical nominal variables don’ t follow a natural order, like the “b” statement. Babies could be boys or girls. When they have a hierarchy they are ordinal, for example, the “e” statement. They have an order. The firstborn is before than the middle child.
When the variable can be measured, it is a numerical variable. If the variable can be measured on a continuous scale, like “c” and “d” statement, then it is a continuous numerical variable. You can find any value on the scale. For example, the amount of fluid could be 250 ml, 250.1 ml, 249.5 ml.
If the variable can also take some finite variables, then it is a numerical discrete variable. These variables represent counts, as in the “a” statement, the number of students in a class.
I’m confused there are no numbers ?
Answer:
Step-by-step explanation:
ur mom
Answer:
the solution is (5,5)
Step-by-step explanation:
if you plug in (5,5) where the x and y are you will find that the equation will balance out.
