Answer:

0.9451

Step-by-step explanation:

Remaining question? <em>"How is the result affected by the additional information that the survey subjects volunteered to​respond?"</em>

Probability that at least 1 user is more careful about personal information when using a public Wi-Fi hot spot is:

P(X≥1) = 1 − P(X<1)

= 1 − P(X=0)

= 1 - [(3,0) (0.62)^0 (1-0.62)^3-0

= 1 - 0.054872

= 0.945128

= 0.9451

Thus, the probability that among three randomly selected Internet users; at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.9451

X + 5 &lt; –4<br><br> Solve for x.<br> Answer must be simplified.
Monica [59]

Answer:

x < -9

Step-by-step explanation:

Hi there,

To isolate the variable x, you do the same steps like solving a regular equation.

x + 5 < -4      ← subtract 5 from both sides to make x by itself

x < -9            ← final answer (already in simplest form)

Hope this explanation helps. Cheers.

I need help :( (please explain how you got your answer too)

Answer:

a. fly = 5.7

b. fly = 7.5

Step-by-step explanation:

a.

hoist/fly = 1 / 1.9

The new hoist is 3. To get this you have to multiply 1 by 3. That means you have to multiply 1.9 by 3 too.

1.9 * 3 = 5.7

b.

hoist/fly = 3/5 (this is the new ratio)

4.5 / 3 = 1.5

5 * 1.5 = 7.5
