If is -(-13/12) then A. -13/-12

If is -13/12 then B. 13/-12

$-\dfrac{-13}{12}=\dfrac{-13}{-12}=\dfrac{13}{12}\\\\\dfrac{-13}{12}=-\dfrac{13}{12}=\dfrac{13}{-12}$

Please calculate the probability using the following equations (in document)

labwork [276]

Substitute u = t ³/2592 and du = t ²/864 dt. Then

$P(T)=1-\displaystyle\int_0^T f(t)\,\mathrm dt=1-\displaystyle864\left(1.1574\times10^{-3}\right)\int_0^{\frac{T^3}{2592}}e^{-u}\,\mathrm du$

The probability that a 12 hour surgery is successful is P (12), so letting T = 12 gives

$P(12)\approx1-\displaystyle\int_0^{\frac23}e^{-u}\,\mathrm du\approx e^{-\frac23} \approx \boxed{0.5134}$

Given: y= 2x + 1 and - 4x + y = 9, solve the system by substitution

kicyunya [14]

Answer:

x=-4 y=-7

Step-by-step explanation:

-4x+y=9 get y alone

add 4x both sides

y=4x+9

insert into y=2x+1

2x+1=4x+9

subtract 1 both sides

2x=4x+8

subtract 4x both sides

-2x=8

divide by -2

x=-4

y=2x+1

y=2(-4)+1

y=-8+1

y=-7

check

-4(-4)+(-7)=9

-16+(-7)=9

9=9

x=-4

y=-7
