= 2x + 11

Steps

(8x+9) -(6x-2)

Remove ( a ) = a

8x + 9 - 6x + 2

Simplify

8x+ 9 - 6x + 2: 2x + 11

= 2x + 11 <----- your answer

A movie-theater employee notes an inverse relationship between the theater's popcorn sales and its nacho sales. On a given night
mario62 [17]

Using proportions, it is found that $1,225 is earned from nachos.

  • This question is solved by <em>proportions</em>, using a rule of three.
  • The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.
  • When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?

The <em>rule of three</em> is:

$1,540 - $1,330

$1,672 - $x

Applying line multiplication:

1672x = 1540 \times 1330

x = \frac{1540 \times 1330}{1672}

x = 1225

$1,225 is earned from nachos.

Suppose A and B are mutually exclusive events, and that P(B)=0.03 and P(A OR B)=0.52. Find P(A)
Angelina_Jolie [31]

Answer:

P(A) = 0.49

Step-by-step explanation:

Given:

A and B are mutually exclusive events.

P(B) = 0.03

P(A or B) = 0.52

If two events A and B are mutually exclusive events, then there are no elements common in both the events. So, the probability of their intersection is 0.

Now, as per probability addition theorem:

P(A or B) = P(A) + P(B) + P(A and B)

For mutually exclusive events, P(A and B) = 0. So,

P(A or B) = P(A) + P(B) + 0

P(A or B) = P(A) + P(B)

Plug in the given values and solve for P(A). This gives,

0.52 = P(A) + 0.03

P(A) = 0.52 - 0.03

P(A) = 0.49

Therefore, the probability of occurrence of event A is P(A) = 0.49.
