If tomatoes are $3.22 per pound and Nico spends $5.76 on tomatoes, how many pounds did he purchase?
juin [17]

In order to find out the amount of pounds of tomatoes purchased:

  • We have to know how much one pound is ($3.22 per pound)

  • Total Nico spent ÷ Price per pound

    So it would be

  • 5.76 ÷ 3.22 = 1.78881987578

Rounding our decimal number:

  • If we round to our nearest tenths it would now be 1.8

Answer:

Therefore, the total number of pounds Nico purchased for $5.76 is 1.8lb.

A box has 1 red marble, 3 blue marbles, and 4 green marbles. Maya draws a blue marble randomly from the box, replaces it, and th
allochka39001 [22]

Answer:

\dfrac{9}{64}

Step-by-step explanation:

Sampling with replacement means that we choose a marble, note its colour, put it back and shake the box, then choose a marble again.

There are 1+3+4=8 marbles in total. The probability that the first chosen marble is blue is \dfrac{3}{8}. then Maya replaces this marble and the probability of choosing the second blue marble is the same. Using the product rule, the probability of drawing 2 blue marbles in a row is

\dfrac{3}{8}\cdot \dfrac{3}{8}=\dfrac{9}{64}.

Help please................
Zinaida [17]
The answer is yes she incorrectly graphed using the points (-2,4) instead of the point (4,-2). This is the answer because if you solve the equation given you should get y=-3/5x+2/5 so a and e will be wrong and if you plug one of the points in you will give a untrue statement so its not d so you are left with b and c so you plug in the end request and you get a true statement with b equaling -2 if you plug in 4 in for x
