Use inverse operations to find the inverse of y = 27x?<br> The inverse of y = 27x3 is y =
VLD [36.1K]

Answer:

  y = (∛x)/3

Step-by-step explanation:

To undo the multiplication by 27, you multiply by its inverse:

  (1/27)y = (1/27)(27x^3)

  y/27 = x^3 . . . . . . . . . . . simplify

To undo the cube, you take the cube root:

  (∛y)/(∛27) = ∛(x^3)

  (∛y)/3 = x

Apparently, you want the inverse function, so you swap the variables:

  y = (∛x)/3

_____

You can swap the variables at the beginning or end. It doesn't matter. If you do it at the beginning, you have ...

  x = 27y^3

and you're solving for y. You use the same inverse operations that we used above.

A special deck of cards has ten cards. Four are green, three are blue, and three are red. When a card is picked, its color of it
nata0808 [166]

Answer:

P(A) = 3/20

Step-by-step explanation:

P(A)=P(blue)P(head)=(3/10)(1/2)=3/20

as there are 10 cards in total, out of which 3 are blue so the probability to get the blue card is, P(blue) = 3/10. and the probability of getting a head when a coin is tossed is P(head) = 1/2.

So in total

P(A) = P(blue)*p(head) = (3/10)*(1/2) = 3/20 = 0.15
