Answer:

0.321 (Answer D)

Step-by-step explanation:

Note that the event "A and Y" happens 9 times. That's 9 times out of (6+9+8+5) outcomes, or 28 outcomes.

Hence, P(A and Y) = 9/28, or 0.321 (Answer D)

Find a parametrization, using cos(t) and sin(t), of the following curve: The intersection of the plane y= 5 with the sphere

Elenna [48]

Answer:

The parametrization, of the given curve is $x = 10 cos(t) \ \ ,z = 10 sin(t)$

Step-by-step explanation:

From the question we are given the function

$x^2 + y^2 + z^2 = 125$

At y= 5

$x^2 + 5^2 +z^2 =125$

$x^2 + z^2 = 100$

$x^2 + z^2 = 10^2$

Converting the above to it polar equation we have

$x = 10 cos(t) \ \ ,z = 10 sin(t)$
