Answer:

The responsess to the given question can be defined as follows:

Step-by-step explanation:

$P(medication\ used) = 0.007 \\\\P( drug \not\ used ) = 1 - 0.007 = 0.993\\\\P(test\ positive | medication \ used) = 0.96 \\\\ P(test \ negative | medication \ used) = 1 - 0.96 = 0.04\\\\$

$P(Point | Non-used\ medication )=0.93\\\\ P(Point |No\ medication ) = 1 - 0.93 = 0.07$

As per the given info we draw the tree diagram which is defined in the attachment file.

$P ( test \ is\ positive ) = P( medication \ used ) \times P( Test \ positive | medication \ used ) + P( medication not \ used ) \times P( Test\ positive | medication \ not \ used )$

$= ( 0.007 \times 0.96 ) + ( 0.993\times 0.07 )\\\\= 0.0762$

$P( medication \ used | test\ positive )= \frac{\textup{P( medication used ) *P( Test positive given medication used )}}{\textup{P( medication used )}}$

$= \frac{( 0.007\times 0.96 )}{0.0762}\\\\= 0.0882$

On saturday, you bowl at mar vista bowl, where renting shoes costs $2 and each game bowled is $3.50. on sunday, you bowl at pinz

ExtremeBDS [4]

Given, at Mar Vista bowl the cost of renting shoes = $2.

The cost for each game bowled = $3.50

There are g games given. So the cost for g games bowled = $ $(3.50)(g)$ = $ $(3.50g)$

The total amount soent at Mar Vista Bowl = $ $(2+3.50g)$

At Pinz, the cost for shoe rental = $5.

The cost for each game bowled = $3.25.

So the cost for g game bowled = $ $(3.25)(g)$ = $ $(3.25g)$

Total amount spent at Pinz = $ $(5+3.25g)$

Given, the amount spent ateach of the places is same.

so we can write the equation as,

$2+3.50g = 5+3.25g$

We will move 3.25 to the left side by subtracting it from both sides. we will get,

$2+3.50g-3.25g = 5+3.25g-3.25g$

$2+0.25g = 5$

Now we will move 2 to the right side by subtracting 2 from both sides. We will get,

$2+0.25g-2 = 5-2$

$0.25g = 3$

Now to get g we will divide 0.25 to both sides. We will get,

$\frac{0.25g}{0.25}= \frac{3}{0.25}$

$g =\frac{3}{0.25}$

$g = 12$

So we have got the required answer.

The number of games bowled = 12.

$\dfrac{x}{ - 3} < - 4 \\\\ x > 12$

P. S. The inequality sign changed or flipped when there's a negative figure involved.

Hope this helps. - M
