A bakery in Hong Kong regularly orders carton of cranberries from Australia. The net weight (in ounces) of
cranberries of a random sample of 20 cartons were as follow:
160 170 170 190 210 240 240 240 270 280
290 290 300 420 500 520 530 610 630 650
(c) The bakery orders the cranberries from Australia with currency exchange rate of AUD 1 to HKD 5.8.
For each ounce of Australia cranberries costs AUD 2 and the fixed shipping fee of each carton is HKD
80. Find the mean, standard deviation, range, and third quartile of the payment (in HKD) of ordering a
carton of cranberries from Australia to Hong Kong.
Answer:
i) Mean = 1933.1817
ii) Range = 5684
iii) Third quartile = 6054
Step-by-step explanation:
Given data :
currency exchange rate : 1 AUD = 5.8 HKD
cost of each ounce = 2 AUD
Fixed shipping cost for each carton = 80 HKD
number of cartons = 20
next determine the total cost of the 20 cartons in HKD
= ∑(weight in ounce * cost of each ounce *exchange rate) +fixed shipping cost
= ∑ ( 160*2*5.8 + 80 ) + -------------- + (650 *2*5.8 + 80 ) ----------------- ( 1 )
= 81756 HKD
i) find the mean value ( X )
= Total cost / number of cartons
= 81756 / 20 = 4087.8
ii) Find the standard deviation
= [tex]\sqrt{\frac{(1936-4087.8)^2+-----+(7620-4087.8)^2}{20-1} }[/tex] note: std = √∑(xi-X )^2 / (n-1)
= 1933.1817
iii) Find the range
Range = highest cost - lowest cost ( values gotten from equation 1 )
= 7650 - 1936
= 5684
iv) Determine the third quartile
third quartile = 6054
attached below is the detailed solution
Solve for the unknown in the following diagram. Round the answer to two decimal places.
in
Answer:
172.27 in
Step-by-step explanation:
Apply the Sine Rule
Sine Rule is given as:
[tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]
c = x = ?
C = 180 - (52 + 48) = 80° (sum of triangle)
b = 130 in.
B = 48°
Plug in the values
[tex] \frac{130}{sin(48)} = \frac{x}{sin(80)} [/tex]
Multiply both sides by sin(80)
[tex] \frac{130*sin(80)}{sin(48)} = x [/tex]
172.274641 = x
x = 172.27 in. (to 2 decimal places)

Two cars start towards each other from points 200 miles apart. One car travels at 40 miles
per hours and the other travel at 35 miles an hour. How far apart will the two cars be after
four hours of continuous travelling?
(a) 20
(b) 40
(c) 75
(d) 100
Answer:
D) 100
Step-by-step explanation:
Solution: After four hours, one car travels 40 x 4 = 160 km, and the other car travels 35 x 4 = 140 km. Therefore, the two cars are 160 + 140 - 200 = 100 km apart

If an equilateral triangle has a height of 8 metres find the length of each side. Round your answer to 2 decimal places.
Answer:
9.24 m to 2 DP's.
Step-by-step explanation:
Consider the right triangle formed from a side , altitude and 1/2 the base.
By pythagoras:
x^2 = 8^2 + (0.5x)^2 where x is the length of each side.
x^2 - 0.25x^2 = 64
0.75x^2 = 64
x^2 = 64/0.75 = 85.3333.
x = 9.2376 m.

Figure o of a tile pattern has 3 tiles. This pattern grows
by 5 tiles each figure.
Answer:
Figure 0 = 5 tiles
Figure 1 = 5 + 7 = 12 tiles
So, the equation is:
y = 7x + 5
because, it adds 7 tiles in every new figure.
The equation is y = 7x +5.
Answer is y = 7x +5

The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
The amount to deposits so that after 5 years, 10,000 is the amount is
$7,440.94
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
r = 6%
n = 2
A = $10,000
t = 5 years
A = P [tex](1 + r/n)^{nt}[/tex]
P = 10,000 / [tex](1 + 0.03)^{10}[/tex]
P = 10,000 / [tex](1.03)^{10}[/tex]
P = $7,440.94
Thus,
The amount to deposits so that after 5 years, 10,000 is the amount is
$7,440.94
