Answer:

Step-by-step explanation:

let E be the event : “the patient shows improvement”

D be the event : “the patient was given the drug”

here we are in a conditional probability situation:

Let E/D be the event “a patient shows improvement ,if it is known that the patient was given the drug”

$p\left( E|D\right) =\frac{p\left( E\cap D\right) }{p\left( D\right) }$

$=\frac{270}{800}$

$=0.3375$

Answer:

.3375

Explanation:

Total people who were given drug: 800

Total people who showed improvement: 270

Probability:

$\boxed{ \sf \dfrac{favorable \ outcomes }{total \ possible \ outcomes}}$

<em>insert values</em>

$\rightarrow \sf \dfrac{270}{800}$

<em>simplify</em>

<em /> $\rightarrow \sf \dfrac{27}{80}$

<em>in decimals</em>

$\rightarrow \sf 0.3375$

Tell whether the relation is a function (3,-2)(0,1)(1,0)(-2,-1)(2,-1)

GREYUIT [131]

Have a look at the first elements of each point: {3, 0, 1, -2, 2}. Since these are all different, no one x value has more than one y-value associated with it, and thus (3,-2)(0,1)(1,0)(-2,-1)(2,-1) is a function.

Find an equation for the line that passes through the points (-1,2) and (5,5)

sesenic [268]

Answer:

-The equation for the problem:

$y = \frac{1}{2}x + \frac{5}{2}$

Step-by-step explanation:

-First, you need determine the slope of a line:

$m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ (where $(x_{1},y_{1})$ is the first coordinate and $(x_{2},y_{2})$ is the second coordinate).

-Use both points $(-1,2)$ and $(5,5)$ for the formula:

$m = \frac{5-2}{5+1}$

$m = \frac{3}{6}$

$m = \frac{1}{2}$

-After you have found the slope, use the point-slope formula and use the slope $\frac{1}{2}$ and the first coordinate, which is $(-1,2)$ , to solve the equation and put it in slope-intercept form:

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

$y-2 = \frac{1}{2} (x+1)$

-Solve:

$y-2 = \frac{1}{2} (x+1)$

$y-2 = \frac{1}{2}x + \frac{1}{2}$

$y = \frac{1}{2}x + \frac{5}{2}$

So, therefore the equation is $y = \frac{1}{2}x + \frac{5}{2}$ .
