Grumpy Corp drug tests all of the recent college graduates it hires each year. The drug test currently used correctly determines

Vedmedyk [2.9K]

Answer:

Hence, the probability of a Negative test is $P(T^C)=0.5904$ .

Step-by-step explanation:

(a)

Let $D=$ Drug user and $T=$ Test positive

Probability of drug users $P(D)=36\%=0.36$

$P(\frac{T}{D})=96\%=0.96$

$P(\frac{T^c}{D^c})=90\%=0.90$

(b)

Find the Probability of a Negative test,

$P(T^C)=P(\frac{T^C}{D^C})\cdot P(D^C)+P(\frac{T^C}{D})\cdot P(D)$

$\Rightarrow P(T^C)=0.9\cdot(1-0.36)+(1-0.96)\cdot 0.36$

$\Rightarrow P(T^C)=0.9\cdot 0.64+0.04\cdot 0.36$

$\Rightarrow P(T^C)=0.576+0.0144$

$\Rightarrow P(T^C)=0.5904$

A family went to a baseball game. The cost to park cars was $5 and the cost per ticket was $21. Write a linear function in the f

Sophie [7]

Answer:

The total cost $y$ in dollars of going to the baseball game for $x$ people of a family can be given as:

$y=21x+5$

Step-by-step explanation:

Given:

At a baseball game:

Cost of car parking = $5

Cost per ticket = $21

To write an equation in the form of $y=mx+b$ representing the total cost of going to the baseball game.

Solution:

The total number of people in the family is = $x$

Using unitary method to find the cost of tickets for $x$ persons.

If 1 ticket costs = $21

<em>Then, $x$ tickets will cost in dollars</em><em> = </em> $21x$

Fixed rate for car parking = $5

Thus, the total cost $y$ in dollars of going to the baseball game for $x$ people of a family can be given as:

$y=21x+5$
