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
<u>i) find the mean value ( X ) </u>
= Total cost / number of cartons
= 81756 / 20 = 4087.8
ii) Find the standard deviation
= note: std = √∑(xi-X )^2 / (n-1)
= 1933.1817
<u>iii) Find the range </u>
Range = highest cost - lowest cost ( values gotten from equation 1 )
= 7650 - 1936
= 5684
<u>iv) Determine the third quartile </u>
third quartile = 6054

Answer:
$0.1
Step-by-step explanation:
From the information given, you know that Mikayla and Weatha spent the same amount of money and because of that you can write the following:
6.25+75x=4.75+90x, where x is the price of a small piece of candy
Now, you can solve for x:
6.25-4.75=90x-75x
1.5=15x
x=1.5/15
x=0.1
According to this, the answer is that a small piece of candy costs $0.1.
Answer:
414 have a great day :)
Step-by-step explanation:
(54−32)(9.2)
=(54−9)(9.2)
=(45)(9.2)
Sale price = original price - discount
discount = 44% of original price = 44% of $37 = 0.44 x 37 = $16.28
Sale price = $37 - $16.28 = $20.72
