Using the table below, find the mean and median of the set of data.
Note: Round all numbers to the nearest tenth.
Answers
Using their concepts concept, we have that:
a) The mean of the data-set is of 81.6.
b) The median of the data-set is of 80.
What is the mean?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
In this problem, there are 2 + 8 + 6 + 3 + 9 = 28 observations, hence the mean is:
M = (70 x 2 + 75 x 8 + 80 x 6 + 85 x 3 + 90 x 9)/28 = 81.6.
What is the median?The median of a data-set is the 50th percentile, the value that separates the median in two halfs.
This data-set has an even number of elements, hence the median is the mean of the 14th and 15th elements, as 28/2 = 14. Both elements are 80, hence the median is of 80.

11. Write four solutions for each of the following equation: (i)7x + 2y = 9 (ii) 2x = -5y
Answers
The solutions of the equations are (0,4.5), (1, 1), (2, -2.5) & (3, -6) and (0,0), (1, -0.4), (2, -0.8) & (3, -1.2)
How to determine the solutions?Equation 1
7x + 2y = 9
Make y the subject
2y = 9- 7x
Divide by 2
y = 4.5 - 3.5x
Let x = 0, 1, 2 and 3
y = 4.5 - 3.5 * 0 = 4.5
y = 4.5 - 3.5 * 1 = 1
y = 4.5 - 3.5 * 2 = -2.5
y = 4.5 - 3.5 * 3 = -6
Hence, the solutions of the equation are (0,4.5), (1, 1), (2, -2.5) and (3, -6)
Equation 2
2x = -5y
Make y the subject
y = -0.4x
Let x = 0, 1, 2 and 3
y = -0.4 * 0 = 0
y = -0.4 * 1 = -0.4
y = -0.4 * 2 = -0.8
y = -0.4 * 3 = -1.2
Hence, the solutions of the equation are (0,0), (1, -0.4), (2, -0.8) and (3, -1.2)

Answers
Step by step
First find the least common multiple (LCM) of the 3 nuts. First I checked to see if 26 was a multiple of 78 and 52, yes it is! 26 is the LCM.
26/26 = 1 almond per bag
52/26 = 2 peanuts per bag
78/26 = 3 pecans per bag.
So all 26 bags will contain 1 almond, 2 peanuts and 3 pecans.

A company wishes to manufacture a box with a volume of 40 cubic feet that is open on top and is twice as long as it is wide. Find the width of the box that can be produced using the minimum amount of material.
Answers
The width of the box is 3 ft that can be produced using the minimum amount of material.
What are the volume and surface area of a box?Consider a box with length 'l', width 'w' and height 'h',
Volume V = l × w × h
Surface area S = 2(lw + wh + hl)
Calculation:It is given that,
Volume of the box V = 36 cubic feet and l = 2w
Using the formulae,
V = 2w × w × h = 2w²h ...(1)
S = (2w² + 2wh + 4wh) = 2w² + 6wh ... (2) (here only single lw is considered since it is open top)
From equation (1),
36 = 2w²h
⇒ w²h = 18
⇒ h =18/w²
equation (2) becomes
S = 2w² + 6w(18/w²) = 2w² + 108/w ...(3)
So, for a minimum amount of material, the width of the box is,
On differentiating the surface area w.r.t 'w'
S' = 4w - 108/w²
For a minimum amount, substituting S' = 0 we get,
0 = 4w - 108/w²
⇒ 4w = 108/w²
⇒ 4w³ = 108
⇒ w³ = 27
∴ w = 3 feet
Therefore, the width of the given box is 3 feet.

y = A · cos (2π · x/T) + B (1)
Where:

Answers
The correct statements are Neither was correct and Joe used the height and radius to calculate the slant height.
How to find the square inches of paper needed.The square inches of paper needed A = surface area of cone + area of overlap
Surface area of cone
The surface area of the cone is given by A = πr[r + √(h² + r²)] where
r = radius of cone = 2 in and h = height of cone = 6 in.So, A = πr[r + √(h² + r²)]
A = π × 2 × [2 + √(6² + 2²)]
A = π × 2 × [2 + √(36 + 4)]
A = π × 2 × [2 + √40]
A = π × 2 × [2 + 2√10]
A = 2π[2 + 2√10]
A = 4π + 4π√10
The area of overlap
The area of overlap A' = wL where
w = width of overlap = 1/2 in and L = slant height of cone = √(h² + r²)So, A' = wL
A' = w[√(h² + r²)]
A' = 1/2[√(6² + 2²)]
A' = 1/2[√(36 + 4)]
A' = 1/2[√40]
A' = 1/2 × 2√10
A' = √10
So, the number of square inches of paper needed is A" = A + A'
= 4π + 8π√10 + √10
Since the number of square inches of paper needed is 4π + 4π√10 + √10
So, the correct statements are Neither was correct and Joe used the height and radius to calculate the slant height.
