Based on a​ poll, 60​% of Internet users are more careful about personal information when using a public​ Wi-Fi hotspot. What is
skad [1K]

Answer:

The probability that at least one of them is careful about personal information is 0.9744.

If the survey subjects volunteered to​ respond, then this a voluntary sampling and the estimated probability p may be biased, as only the people interested in the topic participate.

Given the subject of the survey, it is estimated that the ones who answered the survey are more careful about personal information and then the propability p is biased to a higher level than it should be if the sample was random.

Step-by-step explanation:

We can model this with a random variable, with sample size n=4 and probability of success p=0.6.

The probability that k individuals are more careful about personal information when using a public​ Wi-Fi hotspot in the sample is:

P(x=k)=\dbinom{n}{k}p^k(1-p)^{n-k}=\dbinom{4}{k}\cdot0.6^k\cdot0.4^{4-k}

We have to calculate the probability that 1 or more are more careful about personal information when using a public​ Wi-Fi hotspot. This can be calculated as:

P(x\geq1)=1-P(x=0)\\\\\\P(x=0)=\dbinom{4}{0}\cdot0.6^{0}\cdot0.4^{4}=1\cdot1\cdot0.0256=0.0256\\\\\\P(x\geq1)=1-0.0256=0.9744

The probability that 1 or more individuals in the sample are more careful about personal information when using a public​ Wi-Fi hotspot is 0.9744.

PLEASE HELP!!!! WILL GIVE BRAINLIEST!!
Lelechka [254]

Answer:

14

Step-by-step explanation:

The expression is h = 17 + x/6

Replace x by -18

● h = 17 + x/6

● h = 17 + (-18/6)

● h = 17 +(-3)

● h = 17 -3

● h = 14

So the output when x = -18 is 14

How do I solve the inequality?
timurjin [86]
Hello,

if 20+1/2x>0 then |20+1/2x|=20+1/2x
thus 20+1/2x>6
==> 1/2x>6-20
==>x>2*(-14)
==>x>-28

if 20+1/2x<0 then |20+1/2 x|=-(20+1/2 x)
thus -(20+1/2 x)>6
==>20+1/2x<-6
==>1/2 x <-6-20
==>x<2 *(-26)
==>x< -52

Sol =(-infinity, -52[ ∪ ] -28, +infinty)
