Answer:

1. The median number is 14.

2. The most number of movies watched is 20.

3. 6 friends watched betwixt 14-18 movies.

4. 50% watched 6-18 movies.

5. The lower quartile is 6 and it consists of all values from 2-6.

Step-by-step explanation:

It is best to learn from the answers on your own. Also, it is always divided into four sections, each section has 25% of the data, the middle box part has 50% of the data. The median of the whole set lies in the box(the dot). The lower dot is the average of all values under the median. The higher dot is the average of all the values above the median. These dots also mark the range of each quartile(max and minimum). And the dots at the end mark the lowest and highest values recorded when they gathered the data.

Answer: 14, 20, 6, 50, 6

Step-by-step explanation:

Question 1

The median number is the number in the middle, so where the center line is in the middle of the two boxes

median = 14

Question 2

The most number of movies watched is equal to the value that is furthest to the right which is the rightmost dot

most number of movies watched = 20

Question 3

between 14-18, you see that it takes up one box. Each box and whisker takes up 25% or one quarter of data.

so this is 0.25 * 24 total friends = 6 friends

you can also do 24/4 = 6 friends to get the same answer

Question 4

between 6 and 18 takes up two boxes and each box is 25% (a quarter) so the total is

25 + 25 = 50%

Question 5

the lower quartile is where the lowest 25% of data is, so it is where the leftmost edge of the first box is, or where 6 is

so 6 movies watched

What is the solution to the problem expressed to the correct number of significant figures? 15. 11 (142 × 16. 5) = ? A. 2,358 B.

The solution to the problem expressed 2358.

<h3>What is the meaning of significant figure?</h3>

Significant figure It is defined as the minimum number of digit us needed to express a number in scientific notation.

Therefore we get,

$15.11+(142\times16.5)$

First we have to multiply the given digits as per rule.

$=15.11+2343$

Now we will add both the digits, we get

$=2358.11$

As per given expression, we conclude that the number of significant figure is 4.

So, the answer will be, 2358.

Therefore, the correct option is, 2358.

Answer:

$A=\pi \frac{d^2}{4}$

Step-by-step explanation:

The typical equation for the area of a circle is $A=\pi r^2$ . Since the answer choices are in terms of d, the diameter of the circle, you will need to find r in terms of d.
