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

The temperature was 78°F at 3 P.M. Each hour for
polet [3.4K]

Answer:

  66 °F

Step-by-step explanation:

At 4 P.M., the temperature had decreased by 3° from the temperature at 3 P.M., so was ...

  4 P.M. temp = 78 °F -3° = 75 °F

This was repeated until 7 P.M.

  5 P.M. temp = 75 °F -3° = 72 °F

  6 P.M. temp = 72 °F -3° = 69 °F

  7 P.M. temp = 69 °F -3° = 66 °F

The temperature at 7 P.M. was 66 °F.

__

Of course the repeated subtraction can be simplified using multiplication. The subtraction of 3° four times is equivalent to the subtraction of . . .

  (3°)(4) = 12°

That is, the temperature at 7 P.M. is ...

  78 °F -3°×4 = 78 °F -12° = 66 °F

Answers and work for answers please
larisa [96]

Answer:

1) 5 2) 6 3) 1.25 or -1.75

Step-by-step explanation:

1. x^2 - 25 = 0

x^2 - 25 = 0

First, add 25 to both sides!

x^2 = 25

Now square root both sides.

x = 5

2.  (x-2)^2 = 16

First, square root both sides.

(x-2) = 4

Add 2 on both sides.

(x) = 6

x = 6

3. Quadratic Formula = -b ± \sqrt{b^{2}-4ac } / 2a

Substitute in:

-6 ±\sqrt{7^{2} -4(2)(6)} / 2(2)

-6±\sqrt{49 - 48} / 4

Both forms:

-6 + \sqrt{1} / 4

5 / 4 = 1.25

Negative:

-6 - 1 / 4

-7 / 4 = -1.75

What is the property of the equation 3x+5 - 5 = 20-5
Shalnov [3]

Answer:

x=5

Step-by-step explanation:

We simplify the equation to the form, which is simple to understand

3x+5-5=20-5

We move all terms containing x to the left and all other terms to the right.

+3x=+20-5-5+5

We simplify left and right side of the equation.

+3x=+15

We divide both sides of the equation by 3 to get x.

x=5
