7 0

Answer:

Step-by-step explanation:

Let's first arrange it in ascending order :

340, 480, <u>560</u>, 680, 700

<u>560</u> is clearly the median.

Now add an additional score of 700 to the data :

340, 480, <u>560, 680</u>, 700 ,700

<u>560, 680</u> is separating both halves but is not the median

Median = (560+680)/2

             = 1240 / 2

Median  = 620

aalyn [17]

Answer:

A store receives a shipment of 5,000 MP3 players. In a previous shipment of 5,000 MP3 players, 300 were defective. A store clerk generates random numbers to simulate a random sample of this shipment. The clerk lets the numbers 1 through 300 represent defective MP3 players, and the numbers 301 through 5,000 represent working MP3 players. The results are given.

948 628 87 4,987 938 468 3,589 298 2,459 2,286

Based on this sample, how many of the MP3 players might the clerk predict would be defective?

The manager would expect

defective players in the shipment.

A card is chosen at random from a deck of 52 cards. What is the probability that a king or queen is chosen?
Slav-nsk [51]

The answer is B) 2/13.

An easy way to figure this out is to find what the unsimplified probability would be:

Since there are 8 kings and queens in total, the number is:

8/52

But, since these are both even numbers, they can be simplified.

1/4 x 8 = 2

1/4 x 52 = 13

2/13

Since 13 is a prime number, the answer cannot be simplified anymore.
