If x = 2z and y = 3z, find z

LenKa [72]

Answer:36

Step-by-step explanation:

Let name the missing angle in the triangle w.

We know that x+z+w=180

We also know that z+w=3z=y.

That means that w=2z.

x=2z, so, 2z+2z+z=180

z=36

Write the equation of the line that satisfies the following conditions:

eduard

Answer:

a. $y=-x+-5$

b. $y=\frac{4}{3}x+\frac{5}{3}$

Step-by-step explanation:

to solve part a we have the slope of the line and a point, so we use the point-slope equation

$y=m(x-x_{1})+y_{1}$

where $m$ is the slope: $m=-1$ , and $(x_{1},y_{1})$ is the point, so in this case the point is $(0,-5)$ thus $x_{1}=0$ and $y_{1}=-5$ .Thus the equation is:

$y=-1(x-0)+(-5)$

$y=-x+-5$

And for part b we have two points. With the two points we can find the slope and then use the point-slope equation again.

To find the slope we use:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

for the points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ . Since we have the poits: $(1,3)$ and $(-2,-1)$

$x_{1}=1\\y_{1}=3\\x_{2}=-2\\y_{2}=-1$

Thus, the slope:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{-1-3}{-2-1}$

$m=\frac{-4}{-3}$

$m=\frac{4}{3}$

and now using the point-slope equation:

$y=m(x-x_{1})+y_{1}$

$y=\frac{4}{3}(x-1)+3\\y=\frac{4}{3}x-\frac{4}{3} +3\\y=\frac{4}{3}x+\frac{5}{3}$

An ion channel can be in either open (O) or closed (C) states. If it is open, then it has probability 0.1 of closing in 1 micros

iragen [17]

Answer:

a) P (COO) = 0,135

b) P ( SISI) = 0,00015

Step-by-step explanation:

a) the probability of an ion channel in open position is 50 % 0,5

the probability of an ion channel in close position is 50 % 0,5

probability for the following sequence of states COO

to be closed 0,5 (C)

from (C) to pass to open 0,3 (O)

and to stay O is 0,9

Then the probability of the sequence of states COO is

P (COO) = 0,5 * 0,3 * 0,9

P (COO) = 0,135

b) If people are either infected or susceptible, then

Probability of an individual infected is 0,5

Probability of an individual susceptible is 0,5

to pass from susceptible to infected is 0,05

to pass from infected to susceptible is 0,12

then

P ( SISI) = 0,5 * 0,05*0,12*0,05

P ( SISI) = 0,00015

probability for the following sequence of states COO
