Answer from: lolweapon

the 5-pound bag for $2.75 has the lowest price per pound.

Step-by-step explanation:

At the grocery store, she sees a 10-pound bag of potato for $5.90. It means that the cost per pound of potato is

5.9/10 = $0.59

She a 5-pound bag for $2.75. It means that the cost per pound of potato is

2.75/5 = $0.55

She sees a 11/2 pound bag for $0.99. It means that the cost per pound of potato is

5.5/0.99 = $5.56

Therefore, the 5-pound bag for $2.75 has the lowest price per pound.

5 pound bag.

Step-by-step explanation:

We have been given that Rachel sees a 10-pound bag for $5.90, a 5-pound bag for $2.75 and a 1 1/2 pound bag for $0.99. We are asked to find the lowest price per pound.

Let us find unit price per each bag.

$\text{Unit price for 10 pound bag}=\frac{\$5.90}{\text{10 pounds}}$

$\text{Unit price for 10 pound bag}=\frac{\$0.59}{\text{pound}}$

$\text{Unit price for 5 pound bag}=\frac{\$2.75}{\text{5 pounds}}$

$\text{Unit price for 5 pound bag}=\frac{\$0.55}{\text{ pound}}$

$\text{Unit price for 1 1/2 pound bag}=\frac{\$0.99}{1\frac{1}{2}\text{ pounds}}$

$\text{Unit price for 1 1/2 pound bag}=\frac{\$0.99}{1.5\text{ pounds}}$

$\text{Unit price for 1 1/2 pound bag}=\frac{\$0.66}{\text{ pound}}$

Upon comparing all bags, we can see that 5 pound bag costs $0.55 per pound of potato. Therefore, 5-pound bag has the lowest price per pound.

Answer from: Quest

a) one student is chosen from classroom a, then a student is chosen from classroom b.

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b. this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes. this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes. this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes. this makes them dependent events.
