<h3>What is the Box-and-whisker Plot?</h3>
The box-and-whisker plot is a plot that displays the minimum, maximum, median, lower and upper quartile of a data, which is termed as the five-number summary of a data.
Given the data, 20, 23, 28, 14, 13, 24, 18, 11, find the five-number summary:
- Minimum - 11
- Lower Quartile - 13.5
- Median - 19
- Upper Qaurtile - 23.5
- Maximum - 28
Therefore, the box-and-whisker plot of the data, showing the five-number summary, is shown in the image atatched below.

<span>Let the age of the 4th person be F
Sum of the 1st four in line: 4(23), or 92
Sum of 1st 3: 92 - F (excludes the 4th person's age)
Sum of the last 3 in line: 3(34), or 102
</span><span>Sum of last 2: 102 - F (excludes the 4th person's age)
Sum of all 6: 6(27), or 162 (INCLUDES 4th person's age)
We now get: F + 92 - F + 102- F = 162
- F + 194 = 162
- F = 162 - 194
- F = - 32
F, or 4th person's age = -32/-1, or 32

Answer:
a)
Step-by-step explanation:
Square root of 75 (√75) is regarded as a surd function because the value inside the square root sign is not a perfect square. In that case the given value will be splitted into the product of a largest perfect square and a prime number as shown:
√75 = √3×25
√75 = √3×√25
√75 = √3 × 5
√75 = 5√3
a) Based on the above calculation, it can be inferred that his reasoning is incorrect. The value of 3 was supposed to be inside a square root not a whole number i.e √3 × √25
b) Since √75 = 5√3
√75 = 5 × 1.7321
√75 = 8.6605
√75 = 8.661 {to nearest thousand}
Angle KLM=angleNML=90°
the sum of angles in a triangle is 180°
since: angle2=angle3=x
angle1=angle4=y because
180°-90°-x=180°-90°-x
I think the last one
hope this help
