Answer:

The probability is 12/32

Step-by-step explanation:

If there are 12 red marbles and 20 yellow marbles, then there will be a 12/32 chance that you pick a red marble

This is because out of 32 marbles, you have 12 red marbles that you could pick, which gives you a 12/32 chance that you will pick a red marble. This can also be said as a 37.5% chance.

One small tank takes twice as long to fill a tank as a larger pipe does. If it takes the two pipes 40 minutes to fill the tank w

Gala2k [10]

Um... it'll take each pipe 80 mins, bcz if together they take that long, then to find the pipes time separately, you just multiply it by two to show it doing the work the other pipe did as well. Is that what you wanted??

Find the component form of the vector that translates P(4,5) to p'.

Veronika [31]

Answer:

Component form : (-7 , 2)

Step-by-step explanation:

P(4 , 5) = P'(4 +x , 5+y) = P'(-3 , 7)

4 + x = -3

x = -3 - 4

x = -7

5 + y = 7

y = 7 - 5

y = 2

Vector form : -7i + 2j

Component form : (-7 , 2)

Adrianna sold her DVD that cost $20 with an 8% markup. How much did Adrianna make with the 8% markup?

djverab [1.8K]

Let’s find 1% of the markup first.
20 x 0.01 = $0.20
$0.20 x 8 = $1.60 markup.
$20 + $1.60 = $21.60 total.

Adrianna made $21.60 total, including markup.

Hope that helped! :)

A card is drawn at random from a well-shuffled pack of 52 cards. Find the probability that the card drawn is neither a red card

Reil [10]

Number of red cards including 2 red queens = 26
Number of black queens = 2
Therefore, number of red cards including 2 red queens and 2 black queens = 26 + 2 = 28
Number of cards neither a red card nor a queen = 52 - 28 = 24

$P = \frac{ Number \: of \: favourable \: outcomes}{ Total \: numer \: of \: possible \: outcomes}$

$P (neither \: a \: red \: nor \: a \: queen \: card \: ) = \frac{24}{52} = \frac{6}{13}$
