Part A. For finding the quartiles, box plot would be the best to represent the range of scores of the students.
Part B. The first step is to order the data: 2 3 3 3 3 4 5 6 7 8 14. Next, you will find the median. The median is 4. So, second the quartile = 4 The median splits the remaining data into two sets. The first set is 2 3 3 3 3 and the median of this set is 3. So, first quartile = 3. The second set is 5 6 7 8 14 and the median of this set is 7. And the third quartile = 7
I did this test today i know
1 gallon = 16 cups. so 16x3.5=56. so 56 cups
= 12 + (- 6)(n - 1 )
This is an arithmetic sequence with n th term
= 
+ (n - 1)d
here d = - 6 - 0 = 0 - 6 = 6 - 12 = -6 and = 12, hence
= 12 + (- 6)(n - 1)
use this formula to find the 30 th term
= 12 + (- 6 × 29) = 12 - 174 = - 162
Answer:
Step-by-step explanation:
Since each tank is cylindrical, we would apply the formula for determining the total surface area of a cylinder which is expressed as
Total surface area = 2πr² + 2πrh
Where
r represents the height of the cylinder.
h represents the height of the cylinder.
π = 3.14
From the information given,
Height = 1.9
Diameter = 1.4
Radius = diameter/2 = 1.4/2 = 0.7
Total surface area = 2 × 3.14 × 0.7² + 2 × 3.14 × 0.7 × 1.9 = 3.0772 + 8.3524 = 11.4296 m²
Total surface area of the 3 cylinders = 11.4296 × 3 = 34.29 m²
Since a tin of paint covers 5 m², the number of tins paints that Tim will need to buy is
34.29/5 = 6.858
Since the tins of paint must be whole numbers, he needs to buy 7 tins of paints.
