Based on a poll 62% of internet users are more careful about personal information when using a public wifi hotspot. What is the probability that amoung three randomly selected internet users at least one is more careful about personal information when using pubblic wifi hotspot?

Answers

Answer 1

Answer:

0.9451

Step-by-step explanation:

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

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

Answers

Answer:

It is better to to buy from At Food Lion

Step-by-step explanation:

At Harris Teeter: 7 picture frames cost $15

Cost per picture frames = Total cost of picture frames / number of picture frames

= $15 / 7

= $2.14 per picture

At Food Lion: 9 picture frames cost $17

Cost per picture frames = Total cost of picture frames / number of picture frames

= $17 / 9

= $1.89 per picture

The cost of pictures frames Amat Food Lion is cheaper than at Harris Teeter

Kailey correctly graphed the opposite of –3.3 on the number line.

A number line going from negative 5 to positive 5. Point A is between negative 4 and negative 3, point B is between negative 3 and negative 2, point C is at 3.3, and point D is at 3.9.

Which point could be the point Kailey graphed?
A
B
C
D

Answers

Point a because -3 is between -4 and -3

Answer:

C

Step-by-step explanation:

The opposite of  negative 3.3 is positive 3.3 or just 3.3 so therefore the answer would be C as it is slightly ahead of 3 on the number line but not so far as to indicate anything larger.

B.) Reading 250 pages in 5 hours

What is coordinate geometry?

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that each of the options below describes a relationship that you need to graph in a coordinate plane.

The relationship showing the slope of 50 is:-

Driving 450 miles in 9 hours,

Slope = 450 / 9 = 50

Reading 250 pages in 5 hours

Slope = 250 / 5 = 50

Find x and y intercepts!! show work plzzz

Answers

Answer:

(-15, 0) --> x intercept

(0, 15) --> y intercept

Step-by-step explanation:

First, you need to find the equation of the line:

gradient equals 1 --> (6 - 11)/(-9 - (-4))

y = x + c

sub point (-9, 6)

6 = -9 + c

c = 6 + 9

c = 15

Equation of line: y = x + 15

x-intercept is when y = 0

0 = x + 15

x = -15 (that's the x-intercept)

(-15, 0)

y-intercept is when x = 0

y = 0 + 15

y = 15 (this is the y-intercept). The y-intercept is also the contant 'c'

Given A(2, 3), B(8, 7), C(6, 1), which coordinate will make line AB perpendicular to line CD?
D(9, 3)
D(4, 4)
D(3, 3)
D(8, 4)​

Answers

Answer:

The correct option is;

D(4, 4)

Step-by-step explanation:

The given coordinates of the points are, A(2, 3) B(8, 7), C(6, 1), therefore, the coordinates of the point D that will make CD perpendicular to AB will have a slope = -1/m, where, m = the slope of the line segment AB

The formula for finding the slope, m, of a segment, given the coordinates of two points on the straight line segment (x₁, y₁), (x₂, y₂)

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Therefore, for, the segment AB, we have;

m = (7 - 3)/(8 - 2) = 4/6 = 2/3

m = 2/3

Therefore, to make the segment AB perpendicular to the segment CD, the slope of the segment CD will be -1/m = -1/(2/3) = -3/2

The equation of the segment CD in point and slope form is therefore;

y - 1 = -3/2×(x - 6)

y - 1 = -3·x/2 + 9

The standard form of the equation of the segment CD is therefore;

y = -3·x/2 + 9 + 1 = -3·x/2 + 10

y =  -3·x/2 + 10

The point that satisfies the above equation is the point (4, 4) because;

4 =  -3 × 4/2 + 10

The correct option is therefore, D(4, 4).

Segment SW=8 because of the perpendicular bisector theorem. It states that if a point lies on the perpendicular bisector of a segment, then it is equidistant from the endpoints of that segment (i.e., equal length). This makes Segment SW=8

A)  The equation that represents the cost of a pair of swim trunks is;

B) The cost of a pair of swim trunks is; $28.33

How to solve Algebra Word Problems?

Algebraic word problems are defined as questions that require translation of sentences to equations, and thereafter solving those equations.

Let the cost of one pair of swim trucks be s.

We are told that Each beach towel costs $3 less than a pair of swim trunks. Thus;

Cost of each beach trunk = (s - 3)

Jarvis bought 2 beach towels and 3 pairs of swim trunks at a retail store. Thus, we have;

2(s - 3) + s = 79

2s - 6 + s = 79

3s = 79 + 6

3s = 85

s = 85/3

s = $28.33

For which values of x will the rational expression below be unidentified? (x-1)(x+1)/x+2​

Answers

Answer:

C

Step-by-step explanation:

Given

[tex]\frac{(x-1)(x+1)}{x+2}[/tex]

The denominator of the rational function cannot be zero as this would make it undefined.

Equating the denominator to zero and solving gives the value that x cannot be, that is

x + 2 = 0 ⇒ x = - 2 ← excluded value

Answer:

C. -2

Step-by-step explanation:

Any number divided by 0 is undefined. So, find the value of x that will make the denominator(x + 2)  equal to 0:

x + 2 = 0

Subtract 2 from both sides of the equation to find the value of x:

x = -2

The only value of x that could make the denominator 0 is x = -2.
