A bag contains 4 b l u e marbles, 3 w h i t e marbles, and 10 r e d marbles. If a marble is drawn from the bag, replaced, and an

lawyer [7]

Answer:

40/289

Step-by-step explanation:

We can see these two events are independent as Regina replaced marble after drawing one marble.

We can find possible outcomes by adding number of blue, red and yellow marbles.

possible outcomes= 4+3+10= 17

Let us find probability of getting a blue marble on first draw.

$P( blue\ marble)= \frac{4}{4+3+10} = \frac{4}{17}$

Now we will find probability of getting red marble.

$P(red/marble)= \frac{10}{17}$

We can find probability of getting a blue marble and then red marble by multiplying both probabilities.

$P(\text{ Blue then red})=\frac{4}{17}* \frac{10}{17} =\frac{40}{289}$

Jody practiced a piano piece for 500 seconds bill practiced a piano piece for 8 minutes who practiced longer explain

Mrac [35]

Answer:

Jody

Step-by-step explanation:

You can either convert 500 seconds to minutes or 8 minutes to seconds to compare. I'll do both.

There is 60 seconds in a minute. To find the total minutes of 500 seconds, divide 500 by 60 → 8.3, which means that Jody practiced for 8.3 minutes.

To find the total seconds of 8 minutes, multiply 60 seconds per minute by 8 minutes → 60 * 8 = 480 seconds which means that Bill practiced for 480 seconds.

Now you can compare. Jody practiced for 500 seconds, or 8.3 minutes. Bill practiced for 480 seconds, or 8 minutes. Jody practiced longer.
