(x) basically means y, and f'(x) means dy/dx. The x can have a value, so for example, f(x) = 2x + 1, then f(1) = 3.

Find the distance between the pair of points. Round your answer to the nearest hundredth. (-8,19) and (3,5)
Amiraneli [1.4K]

Answer:

<h3>The answer is 17.80 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-8,19) and (3,5)

The distance between them is

d =  \sqrt{ ({ - 8 - 3})^{2}  +  ({1 9 - 5})^{2} }  \\  =  \sqrt{( { - 11})^{2}  +  {14}^{2} }  \\  =  \sqrt{121 + 196}  \\  =  \sqrt{317}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 17.804493...

We have the final answer as

<h3>17.80 units to the nearest hundredth</h3>

Hope this helps you

Construct a 99% confidence interval for the population standard deviation of white blood cell count (in cells per microliter). A
kogti [31]

Answer:

The correct option is 1.148 < σ < 6.015

Explanation:

The 99% confidence interval for the standard deviation is given below:

\sqrt{\frac{(n-1)s^{2}}{\chi^{2}_{\frac{0.01}{2} }} }

Where:

\chi^{2}_{\frac{0.01}{2} }=18.548

\chi^{2}_{1-\frac{0.01}{2}}=0.676

Therefore, the 99% confidence interval is:

\sqrt{\frac{(7-1)2.019^{2}}{18.548} }

1.148

Therefore, the option 1.148 < σ < 6.015 is correct
