A basket contains 2 cartons of white milk, 3 cartons of chocolate milk, and 3 cartons of strawberry milk. A carton of milk is pulled out of the carton without replacement. Then another carton of milk is pulled out without replacement. What is the probability of pulling out 1 carton of chocolate milk followed by another carton of chocolate milk?

Answers

Answer: 3/8.

Step-by-step explanation: You have to write a fraction with the amounts of milk in the denominator and the amount of chocolate in the numerator.

Answer:

3/28

Step-by-step explanation:

Total number of cartons:

2 + 3 + 3 = 8

Let cm be the chocolate milk, there are 3 cartons of cm.

The probability of the first pull of cm is:

P(cm) = 3/8

Then we have 7 total left and 2 cm.

The probability of the second cm is:

P(cm) = 2/7

Now the probability of the two pulls:

P(cm and cm) = 3/8*2/7 = 3/28

what is half of 3/4 teaspoon

One method of finding the answer in the fraction form of 3/8 is

to multiply the fraction 1/2 by 3/4 ,

or, we can divide 3/4 by 2

i.e. 1/2 × 3/4

as, half = 1/2

so, we get,

=> 3/ 2×4

=> 3/8

=>0.375

Hence, One half of 3/4 teaspoon is equal to 3/8 or 0.375 teaspoons.

PLS HELP- Richard and Teo have a combined age of 33. Richard is 15 years older than twice Teo's age. How old are Richard and Teo?

Answers

Answer:

Teo= 9

Richard= 24

Step-by-step explanation:

x= Richard

y= Teo

33-15= 18

18÷2= 9

15+9=24

Teo is 6 years old and Richard is 27 years old.

What is the equation?

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

Let x be Teo's age, then Richard's age is 15 years older than twice Teo's age, or 15 + 2x. The combined age of Richard and Teo is 33, so we can write an equation:

x + (15 + 2x) = 33

Simplifying and solving for x, we get:

3x + 15 = 33

3x = 18

x = 6

So Teo is 6 years old and Richard is 15 + 2(6) = 15 + 12 = 27 years old.

The family’s leaders have pulled off three of the great marketing triumphs of the modern era: The first is selling OxyContin; the second is promoting the Sackler name; and the third is ensuring that, as far as the public is aware, the first and the second have nothing to do with one another.

To the extent that the Sacklers have cultivated a reputation, it’s for being earnest healers, judicious stewards of scientific progress, and connoisseurs of old and beautiful things. Few are aware that during the crucial period of OxyContin’s development and promotion, Sackler family members actively led Purdue’s day-to-day affairs, filling the majority of its board slots and supplying top executives. By any assessment, the family’s leaders have pulled off three of the great marketing triumphs of the modern era: The first is selling OxyContin; the second is promoting the Sackler name; and the third is ensuring that, as far as the public is aware, the first and the second have nothing to do with one another.

If you head north on I-95 through Stamford, Connecticut, you will spot, on the left, a giant misshapen glass cube. Along the building’s top edge, white lettering spells out ONE STAMFORD FORUM. No markings visible from the highway indicate the presence of the building’s owner and chief occupant, Purdue Pharma.

Originally known as Purdue Frederick, the first iteration of the company was founded in 1892 on New York’s Lower East Side as a peddler of patent medicines. For decades, it sustained itself with sales of Gray’s Glycerine Tonic, a sherry-based liquid of “broad application” marketed as a remedy for everything from anemia to tuberculosis. The company was purchased in 1952 by Arthur Sackler, thirty-nine, and was run by his brothers, Mortimer, thirty- six, and Raymond, thirty-two. The Sackler brothers came from a family of Jewish immigrants in Flatbush, Brooklyn. Arthur was a headstrong and ambitious provider, setting the tone—and often choosing the path—for his younger brothers. After attending medical school on Arthur’s dime, Mortimer and Raymond followed him to jobs at the Creedmoor psychiatric hospital in Queens. There, they coauthored more than one hundred studies on the biochemical roots of mental illness. The brothers’ research was promising—they were among the first to identify a link between psychosis and the hormone cortisone—but their findings were mostly ignored by their professional peers, who, in keeping with the era, favored a Freudian model of mental illness.

Concurrent with his psychiatric work, Arthur Sackler made his name in pharmaceutical advertising, which at the time consisted al

A pet store owner, Byron, needs to determine how much food he needs to feed the animals. Byron knows that he needs to order the same amount of bird food as hamster food. He needs four times as much dog food as bird food and needs half the amount of cat food as dog food. If Byron orders 600 packages of animal food, how much dog food does he buy? Let b represent the number of packages of bird food Byron purchased for the pet store.

Answers

Answer:

300 bags of dog food

Step-by-step explanation:

4b + 2b + b + b = 600

(dog) + (cat) + (bird) + (hamster) = 600

8b = 600

b = 75

Byron purchased 75 bags of bird food. He needs 4 times that of dog food. So, he purchased 300 bags of dog food.
