11.

Given:

$y=x^2$

Differentiate with respect to x, we get

$\frac{dy}{dx}=2x$

The given point is (3,9)

Substitute x=3 in the derivative, we get

$\frac{dy}{dx}=2\times\times3=6$

Hence the slope is 3.

12.

Given:

$y=x^2+4$

Differentiate with respect to x, we get

$\frac{dy}{dx}=2x+0$

The given point is (0,4)

Substitute x=0 in the derivative, we get

$\frac{dy}{dx}=2(0)+0=0$

Hence the slope is 0.

The following data give the annual salaries (in thousand dollars) of 20 randomly selected health care workers. 50 72 56 38 46 65

Afina-wow [57]

Answer:

So, the interquartile range is IQR=22.5.

Step-by-step explanation:

Let us write the numbers in ascending order:

34, 37, 38, 40, 44, | 46, 50, 51, 55, 56, |

57, 61, 62, 65, 65, | 68, 68, 72, 73, 76.

We calculate quartile 1:

$Q_1=\frac{44+46}{2}=45$

We calculate quartile 2:

$Q_2=\frac{56+57}{2}=56.5\\$

We calculate quartile 3:

$Q_3=\frac{65+68}{2}=67.5\\$

We calculate the interquartile range:

$IQR=Q_3-Q_1\\\\IQR=67.5-45\\\\IQR=22.5$
