Answer:
Step-by-step explanation:
Given
Required
Determine the period
A sine function is represented as:
Where
By comparing:
and
So:
So, we have:
Hence, the period of the function is
1 Simplify 7x+16+47x+16+4 to 7x+207x+20<span> 7x+20=x<span>7x+20=x</span></span>
2 Subtract 7x from both sides<span> 20=x-7x<span>20=x−7x</span></span>
3 Simplify <span>x-7x<span>x−7x</span></span> to <span>-6x<span>−6x</span></span>
<span>20=-6x<span>20=−6x</span></span>
4 Divide both sides by −6 -20/6=x
5 Simplify 20/6 to 10/3 -10/3=x
6 Switch sides
x=-10/3<span><span><span> </span></span></span>
Answer
The probability that among four randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.979.
Step-by-step explanation:
Since 62% of Internet users are more careful about personal information when using a public Wi-Fi hotspot.
Therefore, the Probability of 62% of Internet users are more careful about personal information when using a public Wi-Fi hotspot is, p=0.62.
We have to find the probability that at least one user is more careful about personal information when using wi-fi hotspot.
Probability of internet users are not more careful about personal information when using a public wi-fi hotspot, i.e
Use Binomial Distribution, i.e,
p=0.62, q=0.38, n=4.
Required Probability
or

=1-0.02085136=0.97914864
Therefore, the probability that at least one users more careful about personal information when using wi-fi hotspot, i.e 0.979(approx).
RESULT:
<u>The result should not be impacted by this because volunteers are likely to have the most relevant responds.</u>
