Answer:
The probability of picking at least three boys is 
.
Step-by-step explanation:
We have to choose 5 people to form a student government.
We have to pick 5 people out of 7 girls and 5 boys.
What is the probability that at least 3 boys are a part of the student government?
The probability of picking 5 people out of 12 girls and boys = 
The probability of picking at least 3 boys excludes the probability of picking 3 girls. The probability of picking 3 girls = 
The probability of picking at least 3 boys = 1 - = 
The probability of picking 5 people and the probability of picking at least 3 boys = × =
Answer:
3rd one
Step-by-step explanation:
Range goes to the y-values
The y values are 16 19 and 16
So the range will be (16,19)
The answer is the fourth choice
Only 19 is a function because a function only has one y value for every x value. For the other graphs, there are at least two y values for each x value.
Answer:
a relationship ( model equation)
Step-by-step explanation:
the relationship specifies how the dependent variable relies on the independent variable.This helps in manipulating of the variable to see its effect/outcome.The relationship can be mathematical or logical ; it can also be a set of algorithm (program) which can be worked on using the independent variables as inputs. Usually the independent variables influence the dependent variables.
