Answer:
i ) $96120
ii ) Singular adult fee in 2012: $186.91
Step-by-step explanation:
( i )
To find the costs of all 560 peoples you:
Multiply the amount of people by the fee,
440 × 198 = $87120
120 × 120 = $9000
Add these go get the sum of member fees: $96120
( ii )
First calculate what 1% of the adult fee would be:
198 ÷ 100 = 1.98 = 1%
Then calculate what 0.1% of the fee:
1.98 ÷ 10 = 0.198 = 0.1%
Now multiply 5 by the value of 1% to get 5% :
5 × 1.98 = 9.9
Then multiply 6 by the 0.1% to get 0.6% :
0.198 × 6 = 1.188
Add these numbers together to get:
1.188 + 9.9 = $11.088 = 5.6%
Due to the fact this question is referring to money we will round this number 2 decimal places (as money does not exceed 2dp)
$11.09
We now subtract this from the 2013 fee to find out the 2012 fee
$198 - $11.09 = $186.91
$186.91 was the cost of a singular adult fee in 2012
Answer:
a. 0.58
b. 0.78
Step-by-step explanation:
a. The probability of egg come from B1 or B2
P(B1) = 3000/10000 = 0.3
P(B2) = 4000/10000 = 0.4
P(P1 ∪ B2) = 0.3 + 0.4 -(0.3)(0.4)
P(P1 ∪ B2) = 0.7 - 0.12
P(P1 ∪ B2) = 0.58
b. The probability that the market received an egg that is acceptable
P(received an egg that is acceptable) = P(B1 acceptable) + P(B2 acceptable) + P(B3 acceptable)
P(received an egg that is acceptable) = 0.80*3000 + 0.90*4000 + 0.60*3000 / 10000
P(received an egg that is acceptable) = 2400 + 3600 + 1800 / 10000
P(received an egg that is acceptable) = 7800 / 10000
P(received an egg that is acceptable) = 0.78
