We are drawing two cards without replacement from a standard​ 52-card deck. find the probability that we draw at least one red c
alina1380 [7]
The probability of drawing only one red card in two draws without replacement is given by:
P(1\ red)=\frac{26C1\times26C1}{52C2}=0.51
The probability of drawing two red cards in two draws without replacement isgiven by:
P(2\ red)=\frac{26C2\times26C0}{52C2}=0.245
The events 'draw one red card' and 'draw two red cards' are mutually exclusive. Therefore the probability of drawing at least one red card is 0.51 + 0.245 = 0.755.

Una persona asegura que su casa tiene forma rectangular y que el perímetro de la misma es de 18 m y que además, su área es de 21
leva [86]

Considerando las fórmulas para el perímetro y el área de un rectángulo, hay que se chega en una <u>eccuación cuadrática sin solución</u>, o sea, las medidas no son posibles y la persona estaba mintiendo.

<h3>¿Cuál es la fórmula para el perímetro y el área de un rectángulo?</h3>

Considerando que las dimensiones son l y w, hay que:

  • El perímetro es: P = 2(l + w).
  • El área es: A = lw.

El <u>perímetro es de 18 m</u>, o sea:

2(l + w) = 18

l + w = 9

l = 9- w.

El <u>área es de 21 m²</u>, o sea:

lw = 21

(9- w)w = 21

-w² + 9 - 21 = 0

w² - 9w + 21 = 0

El discriminante es dado por:

D = 9² - 4 x 1 x 21 = -3.

El discriminante negativo implica que la <u>eccuación cuadrática no tiene solución</u>, o sea, las medidas no son posibles y la persona estaba mintiendo.

Bas_tet [7]

Answer:

Step-by-step explanation:

on the edge of a cliff overlooking the Pacific ocean. You see a sailboat down in the water below you. The angle of depression to the sailboat is 28◦ . A quick tells you that the cliff you’re standing on is 150ft. How far away from the boat are you, in feet, rounded to one decimal place?(30pts)

We solve using the Trigonometric function of TANGENT

tan 28 = 150/x

Look at the picture to see the question.
Andru [333]

Answer:

y = 5/7x + 5

Step-by-step explanation:

If you replace the x and y in the equation with points x and y of point (35, 30) and change the 10 to b you can solve for b which is the what changes from the original equation to this one.

30 = 5/7(35) + b

30 = 25 + b

5 = b

Since the equations are parallel they have the same slope.

This is the equation for a parallel line that passes through point (35, 30):

y = 5/7x + 5

Hope this made sense! Please give Brainliest!
