Troyanec [42]

The correct answer is option B which is P ( A|B) will be ( 4 / 9 ).

<h3>What is probability?</h3>

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Given that:-

  • A locker combination consists of two nonzero digits, and each combination consists of different digits. Event A is defined as choosing an odd number as the first digit, and event B is defined as choosing an odd number as the second digit.

The total sample will have 9 numbers

S = { 1,2,3,4,5,6,7,8,9} = 9

Even Number = { 2,4,6,8} = 4

Odd Number  = { 1,3,5,7,9} = 5

P ( A ) = ( 4 / 9 )

P ( B ) = ( 5 / 9 )

The probability will be calculated as:-

P( A:B ) = \dfrac{P(A)\times P(B)}{P(B)}

P( A:B ) =\dfrac{( 5/9 ) ( 4/9 )}{5 / 9 }

P( A:B ) = 4 / 9

Therefore the correct answer is option B which is P ( A|B) will be ( 4 / 9 ).

Can someone please ecplain transformations for me including rotation.!!!!
bekas [8.4K]
Rotations, reflections, translations, and dilations are all different types of transformations. Rotations rotate or turn the shape around the axis. Reflections mirror the shape across the axis. Translations move the shape up, down, left, or right. Dilations make the shape a different size.

Rudik [331]

Answer:

La situación está representada por el siguiente sistema:

y = 20+2\cdot x

y \ge 50

Donde:

x - Cantidad de rosas vendidas semanalmente.

y - Ganancia semanal, medida en dólares.

Step-by-step explanation:

De acuerdo con el enunciado, Nita gana una cantidad fija cada semana por pasear al perro de su vecino, con un monto de $ 20, mientras que gana en función de la cantidad de rosas a vender, con un valor unitario de $ 2. Si ella desea ganar al menos $ 50, por tanto, se requiere construir el siguiente sistema, conformado por una ecuación y una inecuación:

y = 20+2\cdot x (1)

y \ge 50 (2)

Donde:

x - Cantidad de rosas vendidas semanalmente.

y - Ganancia semanal, medida en dólares.

The voltage V in a simple electrical circuit is slowly decreasing as the battery wears out. The resistance R is slowly increasin
wariber [46]

Answer:

dI/dt= -0,000127 A/s

Step-by-step explanation:

From Ohm's Law we have V = IR . deriving on both sides of equality

dV/dt = dI/dt R + I dR/dt . clearing,   dI/dt = 1/R (dV/dt - I dR/dt)

replacing  by the values ​​of the statement

dI/dt = 1/400Ω (-0,05 V/s - 0,02 A 0,04Ω/s) . making calculations

dI/dt = -0,0508V/s / 400Ω = -0,000127 V/sΩ. simplifying the units

dI/dt = -0,000127 A/s

SOMEONE PLEASE HELP ME WITH THIS ASAP!
bonufazy [111]

Answer:

y=20

Step-by-step explanation:

0.6(y-10)=6

0.6y-6=6

0.6y=6+6

0.6y=12

y=12/0.6

y=20

the mistake is added 10 to both sides
