Answer:
£100.98
Step-by-step explanation:
Step 1: find total price of tickets
Total price of tickets = 6 adults (£12) + 3 child (£6) = 6(12) + 3(6)
= 72 + 18
Total of tickets = £90
Step 2: Find the extra added 10% booking fee
Booking fee added = 10% of £90
= 10/100 × 90
= 0.1 × 90
Adding booking fee = £9
Step 3: Calculate the added 2% that would be added for using credit card
Cheryl would be paying £99 with her credit card (price of tickets + added booking fee = £90 + £9)
2% of £99 = 2/100 × 99
Added credit card charges = 0.02 × 99 = £1.98
Step 4: Calculate the total charge to be paid by Cheryl if she uses her credit card for the payment
Total charge = cost of tickets + added booking fee + credit card charges
= £90 + £9 + £1.98
= <em>£100.98</em>
Answer:
Option A is right
Step-by-step explanation:
Given that approximately 52% of all recent births were boys. In a simple random sample of 100 recent births, 49 were boys and 51 were girls. The most likely explanation for the difference between the observed results and the expected results in this case is
A) variability due to sampling
-- True because there is a slight difference whichmay be due to sampling fluctuations.
B) bias
False because given that 100 random births selected
C) nonsampling error
False. There is no chance for systematic error here.
d) Confounding: There is no confounding variable present inchild birth since each is independent of the other
e) a sampling frame that is incomplete
False because the sampling is done correctly.
Answer:
78
Step-by-step explanation:
Triangle = 18
Rectangle = 42
Other triangle = 18
18 + 18 + 42 = 78
We need to find the expression for " number_of_prizes is divisible number_of_participants". Also there should not remain any remainder left. On in order words, we can say the reaminder we get after division is 0.
Let us assume number of Prizes are = p and
Number of participants = n.
If we divide number of Prizes by number of participants and there will be not remainder then there would be some quotient remaining and that quotent would be a whole number.
Let us assume that quotent is taken by q.
So, we can setup an expression now.
Let us rephrase the statement .
" Number of Prizes ÷ Number of participants = quotient".
p ÷ n = q.
In fraction form we can write
p/n =q ; n ≠ 0.
