Which data set could be represented by the box plot shown below?
Step2247 [10]

Answer:

  (D)

Step-by-step explanation:

The box plot is a visual representation of the 5-number summary of the data. It shows the extremes, the quartiles and the median.

__

Each data set has 11 elements, sorted into increasing order.

<h3>extremes</h3>

The first and last elements of the data set correspond to the ends of the whiskers, so you are looking for a set that ranges from 3 to 18. (This eliminates choice B.)

<h3>median</h3>

The median will be the middle element, the 6th from either end. The vertical line in the box identifies its value as 10. (This eliminates choice A.)

<h3>quartiles</h3>

The first quartile is the middle element of the bottom half of the data set (what remains after the median and above elements are removed). There are 5 elements in the bottom half, so the first quartile is the 3rd one. It is signified by the left end of the box in the box plot. Its value is 7. (This eliminates choice C.)

Similarly, the third quartile is the 3rd element from the right end of the data set. The value 13 in choice D matches the right end of the box in the box plot.

The box plot represents the data set in Choice D.

BC=<br> Round to the nearest hundred
Vera_Pavlovna [14]

Answer:

2.3 units

Step-by-step explanation:

The unknown side is opposite the given angle 50 degrees, and the length of the hypotenuse is 3 units.

Since sin Ф = opp / hyp, we have here sin 50° = x/3, or x = 3 sin 50°.

Using a calculator, we find that the sine of 50° is 0.776.

Therefore, x = 3(0.766) = 2.298 units, or approximately 2.3 units

Marta_Voda [28]

Answer:

The number of pink pens can be 19 .

Step-by-step explanation:

Total Number of pens = 20

Let x be the number of pink pens

We are supposed to find If the probability of choosing a pink pen is close to 1, how many pink pens would you expect to see in Amanda's bag

Probability of choosing a pink pen = \frac{\text{Number of pink pens}}{\text{Total Number of pens}}

Probability of choosing a pink pen =\frac{x}{20}

ATQ

\frac{x}{20}≈1

x≈20

So, the number of pink pens can be 19 .
