Pulse rates (in beats per minute) were collected on a sample of 36 men. The five number summary for the data is as follows: Lo:

algol13

Answer:

27 men had a pulse rate between 56 & 100.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 36

Five number summary:

Lowest value: 56

Lower Quartile: 71

Median: 80

Upper Quartile: 100

Highest value: 140

We have to find the number of men that had a pulse rate between 56 & 100.

56 is the lowest value of data and 100 is the third quartile of data.

Now, the third quartile give 75 percentile of data, thus, 75% of data lies between lowest value and the third quartile.

Thus, 75% of men have a pulse rate between 56 & 100.

Number of men that had a pulse rate between 56 & 100 =

$75\% \times n\\\\=\dfrac{75}{100}\times 36 = 27$

Thus, 27 men had a pulse rate between 56 & 100.

Given g(x)=3/x^2+2x find g^-1(x)

attashe74 [19]

Answer:

Inverse function is: $g^{-1}x=\frac{-x\pm\sqrt{x(x+3)}}{x}$

Step-by-step explanation:

Given Given the function $g(x)=\frac{3}{x^2+2x}$

we have to find the inverse function of g

To find inverse following steps are:

Step 1: Replace g(x) with y

Step 2: Replace every x with a y and every y with x

Step 3: Solve the equation obtained from Step 2 for y.

Step 4: Replace y with g−1(x).

$g(x)=\frac{3}{x^2+2x}$

To find the inverse, let $y=\frac{3}{x^2+2x}$

Now, solve for x

$y(x^2+2x)=3$

$yx^2+2yx-3=0$

$x=\frac{-2y\pm\sqrt{4y^2-4y(-3)}}{2y}$

$x=\frac{-2y\pm\sqrt{4y^2+12y}}{2y}$

$x=\frac{-2y\pm2\sqrt{y^2+3y}}{2y}$

$x=\frac{-y\pm\sqrt{y(y+3)}}{y}$

Replace every x with a y and every y with x , we get

$y=\frac{-x\pm\sqrt{x(x+3)}}{x}$

Replace y with g−1(x).

$g^{-1}x=\frac{-x\pm\sqrt{x(x+3)}}{x}$

So inverse function is: $g^{-1}x=\frac{-x\pm\sqrt{x(x+3)}}{x}$
