1.3. If Sara draws a red ball and DOES NOT RETURN it, and then she goes to draw a green

dimulka [17.4K]

Answer:

Dependent Event

Step-by-step explanation:

Assume that are 10 balls, such that:

$Red = 6$

$Green = 4$

If the balls are replaced after taken, the probability is:

$Pr(Red) = 6/10$

$Pr(Green) = 4/10$

This is referred to as independent event; because each selection do not affect the next or previous selection

However, if the balls are not replaced, the probability is:

$Pr(Red) = 6/10$

$Pr(Green) = 5/(10 - 1) = 5/9$

We subtracted 1 because there is a reduction in the number of balls when the red ball is not returned.

This is referred to as independent event; because a selection affects the next selection

Use the shell method to find the volume of the solid generated by revolving the region bounded by the line y=x+2 and the parabol

Viktor [21]

Answer:

8 π or

25.13 unit^3 to the nearest hundredth.

Step-by-step explanation:

(A)

The height of the shell is (2 + x - x^2) and the radius is (2 - x).

V = 2π ∫(2 - x)(x + 2 - x^2) dx between the limits x = 0 and x = 2.

= 2π ∫ (2x + 4 - 2x^2 - x^2 - 2x + x^3) dx

= 2π ∫ (x^3 - 3x^2 + 4 ) dx

= 2π [ x^4/4 - x^3 + 4x ] between x = 0 and x = 2

= 2 π [4 - 8 + 8 )

= 2 π * 4

= 8π

= 25.13 unit^3 to the nearest hundredth.
