We first group the like terms
-9h + 12h - 6 + 40 = 22
We now make h the subject
-9h + 12h = 2 + 6 - 40
Evaluate
3h = -12
h = -12/3

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,

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

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

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

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

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

Y= -x + 2 and y= 3x - 4
As these both equal y, you know that they both equal each other so
-x + 2 = 3x - 4

A taxi service charges a flat fee of $1.25 and $0.75 per mile. if henri has $14.00, which of the following shows the number of m

andrey2020 [161]

Option m = 17

y = total cost of the service
m = number of miles run

y = 1.25 + 0.75 m

Equal the cost to the amount available by Henri

14 = 1.25 + 0.75m

Solve for m

m = (14 - 1.25)/0.75 = 12.75 / 0.75 = 17 miles.
