Answer:
(a)
degree is 4
it is binomial
(b)
degree is 2
it is trinomial
(c)
degree is 3
it is monomial
Step-by-step explanation:
(a)
we are given function as
Degree:
we know that degree is highest exponent value
so, degree is 4
Number of terms:
we can see that there are two terms
so, it is binomial
(b)
we are given function as
Degree:
we know that degree is highest exponent value
so, degree is 2
Number of terms:
we can see that there are three terms
so, it is trinomial
(c)
we are given function as
Degree:
we know that degree is highest exponent value
so, degree is 3
Number of terms:
we can see that there are one term
so, it is monomial

Answer:
0.1333 = 13.33% probability that bridge B was used.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Arrives home by 6 pm
Event B: Bridge B used.
Probability of arriving home by 6 pm:
75% of 1/3(Bridge A)
60% of 1/6(Bridge B)
80% of 1/2(Bridge C)
So
Probability of arriving home by 6 pm using Bridge B:
60% of 1/6. So
Find the probability that bridge B was used.
0.1333 = 13.33% probability that bridge B was used.
Answer:
Step-by-step explanation:
we are given
y varies directly as x
so, we can write equation as
where
k is constant of proportionality
We have
at x=-1 , y=6
so, we can use it to find k
so, we get
now, we can plug it back
now, we can plug x=5
and we get
