Answer:
P(marks ≥ 20) = 0.4
Step-by-step explanation:
Marks gotten by the 5 students are;
15, 14, 20, 17, 25
Marks more than or equal to 20 are 2 in number namely 20 and 25.
Thus, probability of getting marks more than or equal to 20 is;
P(marks ≥ 20) = 2/5
P(marks ≥ 20) = 0.4
Answer:
15cm and 12cm
Step-by-step explanation:
From the question,The ratio of the length and breadth of a rectangle is 5 to 4
We assume The Lenght of the field= 5x
The breadth = 4x
Area= (5x × 4x)= 180
20x^2= 180
X^2=
X= √9
X=3cm
The Lenght of the field= 5×3= 15cm
The breadth = 4×3=12cm

Answer:
See numbers for each part of the box-whisker plot below
Step-by-step explanation:
the left whisker should start at the value 63 (the minimum)
The first Quartile (beginning of the box on the left is at the point 68.5.
The median is the value: 73 (notice this is the actual value at the middle of the list)
The third Quartile (end of the right hand box) is at the point 84.5
the end of the right hand side whisker is at the maximum of your list: 92
