Find the difference ( 9/4​x+6) − (− 5/4​x−24)=​

Answer:

=\frac{7}{2}x+30

Step-by-step explanation:

So we have the equation:

(\frac{9}{4}x+6)-(-\frac{5}{4}x-24})

First, distribute the negative on the right:

=(\frac{9}{4}x+6)+(\frac{5}{4}x+24})

Combine like terms:

=(\frac{9}{4}x+\frac{5}{4}x})+(6+24)

Add:

=\frac{14}{4}x+30

We can reduce our fraction by dividing both layers by 2. Thus:

=\frac{7}{2}x+30

So this would be our answer :)

Joe owns a stock which has probability .5 of going up. This morning, he bought a ticket in a lottery game which gives him a prob
Anit [1.1K]

Answer:

The probability that Joe's stock will go up and he will win in the lottery  is 0.00005.

Step-by-step explanation:

Let the events be denoted as:

<em>X</em> = the stock goes up

<em>Y</em> = Joe wins the lottery

Given:

P (X) = 0.50

P (Y) = 0.0001

The events of the stock going up is not dependent on the the event of Joe winning the lottery.

So the events <em>X</em> and <em>Y</em> are independent of each other.

Independent events are those events that can occur together at the same time.

The joint probability of two independent events <em>A</em> and <em>B </em>is,

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

Compute the value of P (<em>X ∩ Y</em>) as follows:

P(X\cap Y)=P(X)\times P(Y)=0.50\times 0.0001=0.00005

Thus, the probability that Joe's stock will go up and he will win in the lottery  is 0.00005.
