g Based on a​ poll, 61​% of Internet users are more careful about personal information when using a public​ Wi-Fi hotspot. What

is 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? How is the result affected by the additional information that the survey subjects volunteered to​ respond? The probability that at least one of them is careful about personal information is nothing. ​(Round to three decimal places as​ needed.) How is the result affected by the additional information that the survey subjects volunteered to​ respond? A. It is very possible that the result is not valid because not everyone uses public​ Wi-Fi. B. It is very possible that the result is not valid because the sample may not be representative of the people who use public​ Wi-Fi. C. The result should not be impacted by this because there is no reason to lie when responding. D. The result should not be impacted by this because volunteers are likely to have the most relevant responses.

Answer: P (atleast one is careful) is

1 - 0.012 =0.988

B) It is very possible that the result is not valid because the sample may not be representative of the people who use public​ Wi-Fi

Step-by-step explanation:

P(not careful) =1 - 0.67 = 0.33

P (4 all not careful) = (0.33)^4 =0.012

P (atleast one is careful) = 1 - 0.012 =0.988

6⋅7-3^2⋅9+4^3 what is the value?
zalisa [80]

\textsf{Hey there!}

\mathsf{Equation: 6 \times 7- 3^2 \times9+4^3}

\mathsf{3^2 = 3\times3=9}

\mathsf{4^3= 4\times4\times4=16\times4 = 64}

\mathsf{6\times7 = 42}

\mathsf{9\times9= 81}

\mathsf{New\ equation: 42 - 81 + 64}

\mathsf{42 -81= -39}

\textsf{New equation: -39 + 64}

\mathsf{SOLVE\ ABOVE\ \uparrow\ \& you\ will\ have\ your\ answer\ to\ this\ problem}

\mathsf{-39 + 64 = 25}

Find angle measures of 4, 5, and 6
Cloud [144]

Answer:

ok

Step-by-step explanation:

ok so the sum mustbe 36

and as this is a parallelogram that means opposite angle are the same and so one of the is 125that means that the opposite is 125 too, the sum is 250

360-250=110 and as one of the side must sum up to the half of 110 which is 55 and substract (55-22=33)

4=33

so is 5 =33

6=22

Inverse of y equals 12 to the x
e-lub [12.9K]

Answer:

f^{-1}(x) = log_{12}(y)

Step-by-step explanation:

We have the following function

y = 12^x, and we need to find the inverse function.

To find the inverse function we should solve the equation for "x". To do so, first, we need to:

1. Take the logarithm in both sides of the equation:

lg_12 (y) = log _12 (12^x)

(Please read lg_12 as: "Logarithm with base 12")

From property of logarithm, we know that lg (a^b) = b*log(a)

Then:

lg_12 (y) = x*log _12 (12)

We also know that log _12 (12) = 1

Then:

x = log_12(y).

Then, the inverse of: y= 12^x is:

f^{-1}(x) = log_{12}(y)

What is the 214 term in the sequence 7,10,13,16?
mixer [17]
We can figure this out using the explicit formula.

f(n)=f(1)+d(n-1)

n represents the term we are looking for.
f(1) represents the first term in the sequence, which in this case, is 7.
d represents the common difference, which in this case, is +3.

f(n) = 7 + 3(n - 1)
f(n) = 7 + 3n - 3
f(n) = 4 + 3n

Now, we can input 214 for n and solve.

f(214) = 4 + 3(214)
f(214) = 4 + 642
f(214) = 646

The 214th term in this sequence is 646.
