Mathematics

Answer:

<h2>d)  .3375</h2>

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} .
