Answer:
The inequality required to express the above condition is x ≥ 18.75
Step-by-step explanation:
Renata and her family go through an average of more than 15 cans of sparkling water each day.
The number of cases of 24 cans of sparkling water.
We can take the number of cases to be x.
Each case is said to cost $3.50.
An inequality for the number of cases that Renata's family go through in 24 days can be written as
x ≥ ⇒ x ≥
⇒ x ≥ 18.75
Therefore the inequality required to express the above condition is
x ≥ 18.75
Answer:
a)
b)
c)
d)
e) The intersection between the set A and B is the element c so then we have this:
Step-by-step explanation:
We have the following space provided:
With the following probabilities:
And we define the following events:
A= [a,b,c], B=[c,d,e]
For this case we can find the individual probabilities for A and B like this:
Determine:
a. P(A)
b. P(B)
c. P(A’)
From definition of complement we have this:
d. P(AUB)
Using the total law of probability we got:
For this case , so if we replace we got:
e. P(AnB)
The intersection between the set A and B is the element c so then we have this:
