A single card is drawn form a standard 52 card deck. Let D be the event that the card drawn is red., and let F be the event that

andrezito [222]

<h2>Answer:</h2>

Hence, the probability is:

0.8846

<h2>Step-by-step explanation:</h2>

D be the event that the card drawn is red.

and F denote the event that the card drawn is a face card.

We are asked to find:

P(D'∪F')

We know that D' denote the complement of event D

and F' denote the complement of event F.

Hence, we have:

$P(D'\bigcup F')=(P(D\bigcap F))'\\\\i.e.\\\\P(D'\bigcup F')=1-P(D\bigcap F)$

D∩F denote the event that the card is a red card and is a face card as well

Since there are 6 cards which are face as well as red cards out of a total of 52 cards.

Hence, we get:

$P(D'\bigcup F')=1-\dfrac{6}{52}\\\\i.e.\\\\P(D'\bigcup F')=\dfrac{52-6}{52}\\\\i.e.\\\\P(D'\bigcup F')=\dfrac{46}{52}\\\\P(D'\bigcup F')=0.8846$

Question 3<br> Find the measure of the given arc.<br> mWVY

forsale [732]

Given:

m(ar XW) = 47.3°

To find:

The measure of arc WVY

Solution:

In the given figure XW and XY are equal arcs.

m(ar XY) = m(ar XW)

m(ar XY) = 47.3°

Measure of complete circle = 360°

m(ar WVY) + m(ar YX) + m(ar XW) = 360°

m(ar WVY) + 47.3° + 47.3° = 360°

m(ar WVY) + 94.6° = 360°

Subtract 94.6° from both sides.

m(ar WVY) + 94.6° - 94.6° = 360° - 94.6°

m(ar WVY) = 265.4°

The measure of arc WVY is 265.4°.

If it is 10:00 am at your location when it is noon along the prime meridian, what is your longitude

Rudiy27

Every 15 degrees along the line of longitude is equivalent to a time difference of 1 hour.

Given that <span>it is 10:00 am at your location when it is noon along the prime meridian</span>, this means that you are 2 hours behind the prime meridian.

The prime meridian is 0 degrees and you are 2 x 15 = 30 degrees west of the prime meridian.

Therefore, your longitude is 30 degrees west.
