Answer:

7,500 seconds

Step-by-step explanation:

First you must find how many 10,000 points are in 5 million:

5,000,000 ÷ 10,000 = 500

Then, multiply that number by 15 seconds. To find how long it will take. And that will give you the answer:

500 x 15 = 7,500 seconds

Hope this helps you out! : )

You could set up the equation as X^2=4X (3), and then simplify the equation to X^2 =12X, you can divide X from both sides, leaving you with X=12

Here are the prices for cans of juice that are the same brand and the same size at different stores. Which store offers the best

Hitman42 [59]

Answer:

Store Z

Step-by-step explanation:

Store X: 4 cans for $2.48, so 2.48/4= $0.62 per can

Store Y: 5 cans for $3.00, so 3.00/5= $0.60 per can

Store Z: $0.59 per can

Store Z offers the best deals since it cost less than the other

Please answer There is a bag filled with 3 blue and 5 red marbles. A marble is taken at random from the bag, the colour is noted

Misha Larkins [42]

Answer:

$\frac{15}{28}$ is the required probability.

Step-by-step explanation:

Total number of Marbles = Blue + Red $= 3 + 5 = 8$

Probability of getting blue $= \frac{3}{8}$

Probability of not getting a blue $=\frac{5}{8}$

To get exactly one blue in two draws, we either get a blue, not blue, or a not blue, blue.

<u>First Draw Blue, Second Draw Not Blue:</u>

1st Draw: $P(Blue) = \frac{3}{8}$

2nd Draw: $P(Not\:Blue)=\frac{5}{7}$ (since we did not replace the first marble)

To get the probability of the event, since each draw is independent, we multiply both probabilities.

$P(Event)=\frac{3}{8}\cdot \frac{5}{7}=\frac{15}{56}$

<u>First Draw Not Blue, Second Draw Not Blue:</u>

1st Draw: $P(Not\:Blue)=\frac{5}{8}$

2nd Draw: $P(Not\:Blue)=\frac{3}{7}$ (since we did not replace the first marble)

To get the probability of the event, since each draw is independent, we multiply both probabilities.

$P(Event)=\frac{5}{8}\cdot \frac{3}{7}=\frac{15}{56}$

To get the probability of exactly one blue, we add both of the events:

$\frac{15}{56}+\frac{15}{56}=\frac{15}{28}$
