Answer:
The probability that a randomly selected consumer will recognize Amazon is 0.988.
Step-by-step explanation:
The data given in the question is
Total number of consumers = 795 + 10 = 805
Consumers who knew of Amazon = 795
Consumers who did not know of Amazon = 10
The formula for calculating probability of an event A is:
P(A) = No. of favourable outcomes/Total no. of possible outcomes
P(Recognize Amazon) = No. of Consumers who knew Amazon/Total no. of consumers
P(Recognize Amazon) = 795/805
= 0.98757
P(Recognize Amazon) ≅ 0.988
The probability that a randomly selected consumer will recognize Amazon is 0.988.
If you're multiplying by 10, you're moving the decimal point to the right, the same with any multiplication in the 10's, so 100, 1,000, etc. This is because you are making the number 10 times larger, so if you had 3.4, the 4 is in the 1/10 column so multiplying by 10 would put it in the units column, making the number 34.
On the other hand, dividing by the 10's makes the decimal point move to the left because you are making the number 10 times smaller, so if the units column is worth 1, then 10 times less than that is 1/10, which is the first decimal place.
I hope this helps! I tried to explain it well but let me know if you still don't understand or if I've confused you in any way :)
We divide by 2 on both sides.
We get the final answer as
x = 5/2 = 2.5
Answer:
a) £320
b) £720
c) 2 days
Step-by-step explanation:
The question is all about inputting values and finding a result or rearranging and finding a result.
a) d = 6. C = 50(6)+20 = 320
b) d = 2x7 (7 days a week) C = 50(2x7) + 20 = 720
c) C = 120 ... 120 = 50d+20
100 =50d d = 100/50 = 2
