Answer:
1/5
Step-by-step explanation:
The Constraint is ; those who rode the bus, hence it is conditional because we aren't focused on students, only students who rode the bus.
Now we want the frequency of those who were late Given that they rode the bus : for these we have 3 students
Total number of students who rode the bus , total possible outcome = 15
Hence, the conditional frequency = (number who rode bus and were late / otal number who rode the bus)
Hence, we have ; 3 / 15 = 1 / 5
A: 14/16 that is the answer
Answer:
The value of Discriminant of the function is -92
It has ZERO distinct real number zeros.
Step-by-step explanation:
Given:

Which is a Quadratic Equation in the general form of

where a,b and c are constants.So on comparing the given equation with general form we get,

Formula for discriminant we have

now for zeros we have

on substituting these values we get

or

the term
is imaginary
hence the zeros are not real number
Answer:
1 hour and 7.5 minutes
Step-by-step explanation:
We have the following information:
Jose makes 1 / 1.5 of the job per hour. It is his rate of work in addition to that the partner makes 1 / 4.5 of the job per hour. It is his rate of work.
Thus:
1 / 1.5 + 1 / 4.5 = 1 / x
0.8898 = 1 / x
x = 1 / 0.8888
x = 1.125
Hence, it will take 1 hour and 7.5 minutes for them to complete the job working together.
No, 1 is not a composite number because it needs one positive factor other than 1 and itself
