Jolly had 12 burgers from the start.

if his five friends ate 2, you'd multiply that and get 10, then you add how many Jolly ate, which is 12.

Answer:

12 burgers

Step-by-step explanation:

Let Jolly had x burgers. If he eats two burgers then remaining burgers = (x-2)

Now he divides these remaining burgers among his five friends. Then each friend gets 2 burgers.

So the equation will be

\frac{(x-2)}{5}=2

We further simplify this equation to get the value of x.

(x-2) = 2 × 5

(x-2) = 10

x = 10 + 2

x = 12

Therefore, there were 12 burgers.

Let AA and BB be events such that P(A∩B)=1/73P(A∩B)=1/73, P(A~)=68/73P(A~)=68/73, P(B)=21/73P(B)=21/73. What is the probability
krok68 [10]

Answer:

P(A \cup B) = \frac{5}{73} +\frac{21}{73} -\frac{1}{73}=\frac{25}{73}

Step-by-step explanation:

Let A and B events. We have defined the probabilities for some events:

P(A') =\frac{68}{73} , P(B) =\frac{21}{73} , P(A \cap B) =\frac{1}{73}

Where A' represent the complement for the event A

The complement rule is a theorem that provides a connection between the probability of an event and the probability of the complement of the event. Lat A the event of interest and A' the complement. The rule is defined by: P(A)+P(A') =1

So for this case we can solve for P(A) like this:

P(A) = 1-P(A') = 1-\frac{68}{73}=\frac{5}{73}

And now we can find P(A \cup B) using the total probability rul given by:

P(A \cup B) = P(A)+P(B) -P(A \cap B)

And if we replace the values given we got:

P(A \cup B) = \frac{5}{73} +\frac{21}{73} -\frac{1}{73}=\frac{25}{73}

And that would be the final answer.

ValentinkaMS [17]

Answer:

a. 40

Step-by-step explanation:

Given

g(x)=2x and h(x)=x^2+4

(h\circ g)(x)=h(g(x))

(h\circ g)(x)=h(2x)

We plug in 2x into  h(x)=x^2+4.

(h\circ g)(x)=(2x)^2+4

(h\circ g)(x)=4x^2+4

We now substitute x=-3.

(h\circ g)(-3)=4(-3)^2+4

(h\circ g)(-3)=36+4=40

The correct choice is A.
