How do you find slope? Example: y=7x-4

1 answer:

6 0

This equation is written in slope-intercept form (y=mx+b), which means that the equation will give you the slope and y-intercept. The variable m is the slope, and b is the y-intercept.

Investigators conducting a study regarding the effects of water pollution and peptic ulcer disease obtained the following data:

natima [27]

Answer:

Kindly check explanation

Step-by-step explanation:

The prevalence per 1000 among the exposed :

Total number of diseases among those exposed = 60 + 238 = 298

Prevalence per 1000 among the exposed :

(298 / 9000) * 1000 = 33.11

Prevalence per 1000 among the non exposed :

((90 - 60) + (268 - 238)) / 3000

(60 / 3000) * 1000 = 20

Incidence rate per 1000 among the exposed :

238 / 5940 * 1000

0.0400673 * 1000 = 40.07

Incidence rate per 1000 among the unexposed :

((90 - 30) / (3000-30)) * 1000

(60/2970) * 1000 = 20.2

What is the derivative of arcsin(6x)

schepotkina [342]

$\bf sin^{-1}(6x)\\\\
-----------------------------\\\\
\textit{using the chain-rule}\implies \cfrac{d}{dx}\left[ sin^{-1}(6x) \right]\implies \cfrac{1}{\sqrt{1-(6x)^2}}\cdot 6\\\\ \cfrac{6}{\sqrt{1-36x^2}}$
