AHHHHHHHHHHHHHHH SOMEONE ANSWEER THIS PLEEASEEE NEED ANSWER ASP 20 pts!! Please answer!!! I literally don't get this ;c so PLEAS
Blababa [14]

Answer:

P(A\textrm{ and }B)=\frac{3}{14}

Step-by-step explanation:

Given:

P(A)=\frac{4}{7}

P(B|A)=\frac{3}{8}

We know that, conditional probability of B given that A has occurred is given as:

P(B|A)=\frac{P(A\cap B}{P(A)}. Expressing this in terms of P(A\cap B), we get

P(A\cap B)=P(B|A)\times P(A)

Plug in the known values and solve for P(A\cap B). This gives,

P(A\cap B)=P(B|A)\times P(A)\\P(A\cap B)=\frac{3}{8}\times \frac{4}{7}\\P(A\cap B)=\frac{12}{56}=\frac{3}{14}

Therefore, the probability of events A and B occurring is \frac{3}{14}.

irina1246 [14]

Answer:

See below.

Step-by-step explanation:

2( x+3) = 5(x-4)

Okay, So To Find The Mean, We Need To Look At The Values.
-588,-838,-691,-818,-846,-725,-605,-732,<span>-750
</span>So, We Add Them, Then Divide.
-588+-838+-691+-818+-846+-725+-605+-732+-750
---------------------------------------------------------------------
                                      9
This Is -732.555556.Rounded Is -733
Now, The Median. The Middle Value. 
The Middle Value Is -846.
So, The Mean Is A, 113 Points Higher.
