Which of the following expressions will produce the area of one petal of the curve r = 5 cos 3θ? A) 6 times the integral from 0 to pi over 3 of sine squared of 3 times theta, d theta
B) 6 times the integral from 0 to pi over 6 of 25 times the cosine squared of 3 times theta, d theta
C) 25 times the integral from 0 to pi over 6 of cosine squared of 3 times theta, d theta
D) the integral from 0 to 2 times pi over 3 of the cosine of 3 times theta, d theta

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
