Annette [7]

There is 15 bars in each case.

Subtract 8 from 143 and you get 135.

Divide 135 by 9 and you get 15 :)

The faces of a tetrahedron die are numbered 1 to 4. if each of the 4 sides is equally likely to land down, what is the probabili
Hoochie [10]

The probability distribution for the face landing down =  4/15

<h3>What is the probability?</h3>

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

<h3>According to the given information:</h3>

If we assign 1 probability x

then 2 has probability  1/2 x.

Similarly,

then 3 has probability = 1/2((1/2)*x) = (1/4)*x

so

then 4 has probability = 1/2((1/4)*x) = (1/8)*x

These probabilities need to sum to 1.

Hence:

                x+\frac{1}{2} x+\frac{1}{4} x+\frac{1}{8} x=1

or equivalently

                   (15/8)*x = 1

                       x = 8/15

the probability distribution for the face landing down  = (1/2)*(8/15)

                                                                                         = 8/30

                                                                                         =  4/15

I understand that the question you are looking for is:

A tetrahedral die has four faces, numbered 1-4. If the die is weighted in such a way that each number is twice as likely to land facing down as the next number (1 twice as likely as 2, 2 twice as likely as 3, and so on) what is the probability distribution for the face landing down?

Two planes are 2725 miles apart and are traveling toward each other one plane is traveling 110 mph faster than the other plane T
Licemer1 [7]

Answer:

therefore x  = 600 mph

therefore the speed of the other plane  y = x - 110 = 600 - 110 = 490 mph

Step-by-step explanation:

i) Two planes are 2725 miles apart and are travelling towards each other.

ii) One plane is travelling 110 mph faster than the other plane.

iii) the planes pass each other in 2.5 hours

iv) let the speed of one plane be x mph

v) let the speed of another plane be y mph

vi) therefore x  - y = 110 mph

vii) and also x + y = 2725/2.5 = 1090

viii) adding the equation in vi) to the equation in vii) we get 2x  = 1200

    therefore x  = 600 mph

ix) therefore the speed of the other plane  y = x - 110 = 600 - 110 = 490 mph

One a piece of paper graph this system of inequalities y&lt;-1/3x+3, y&gt;3x+2
kolbaska11 [484]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y < -\frac{1}{3}x+3 ----> inequality A

The solution of the inequality A is the shaded area below the dashed line y=-\frac{1}{3}x+3

The slope of the dashed line is negative

The y-intercept of the dashed line is 3

The x-intercept of the dashed line is 9

y > 3x+2 ----> inequality B

The solution of the inequality B is the shaded area above the dashed line y=3x+2

The slope of the dashed line is positive

The y-intercept of the dashed line is 2

The x-intercept of the dashed line is -2/3

The solution of the system of inequalities is the shaded area between the two dashed lines

see the attached figure
