Answer:

85%

Step-by-step explanation:

The probability of finding our satisfactory service in the three visits in a row would be the multiplication of the probability of each event.

The event is always the same. 95% of the service will be satisfactory. That is a probability of 95/100

Then the final probability would be:

<em>(95/100) * (95/100) * (95/100) = 0.85 </em>

In other words, the probability that a customer who visits three times will find our service satisfactory is 85%

MariettaO [177]

Answer:

Height = 8 cm

You will need this formula (see attached):

Volume = [PI * 8 * (2² + 2*4 + 4²)]  / 3

Volume = [3.14159265 * 8 * (4 + 8 + 16)] / 3

Volume = 234.57 cubic centimeters

Tan^2x+sec^2x=1 for all values of x. <br> true or false?
amid [387]

This is not true.

\tan^2x+\sec^2x=\dfrac{\sin^2x}{\cos^2x}+\dfrac1{\cos^2x}=\dfrac{1-\cos^2x+1}{\cos^2x}=2\sec^2x-1

2\sec^2x-1=1\implies\sec^2x=1\implies\sec x=\pm1\implies x=n\pi

where is n is any integer. So suppose we pick some value of x other than these, say x=\dfrac\pi4. Then

\tan^2\dfrac\pi4+\sec^2\dfrac\pi4=1+2=3\neq1
