Let me help you visualize this one.
Let's say we have 12 chickens.
OOOOOOOOOOOO
We divide this group in half (1/2 who tried to cross the road.)
OOOOOO
And here, we need to get 3/4 of the 6 left.
3/4 can be represented as 0.75 of 1.
6 times 0.75 equals to 4.5.
OOOOC (Woah, that chicken is split in half!)
What fraction is 4.5 of the original amount?
Well, that's for you to find out! Good luck in solving this question.
Answer:
The total number of train tickets Aaron can buy=4
Step-by-step explanation:
a). Determine first expression
Let the number of each mode of transport be as follows;
bus ticket=b
train ticket=t
b). Determine the second expression
Let the total cost be expressed as shown;
total cost=(cost per bus ticket×number of bus tickets)+(cost per train ticket×number of train tickets)
where;
total cost=$520
cost per bus ticket=$64
number of bus tickets=b=3
cost per train ticket=$82
number of train tickets=t
replacing;
(64×3)+(82×t)=520
192+82 t=520
82 t=520-192
82 t=328
t=328/82=4
t=4
The total number of train tickets Aaron can buy=4
Answer:
Step-by-step explanation:
Given given that
- Lower confidence interval = 7.1
- Upper confidence interval = 7.5
- As such, We are 95% confident that it's somewhere between 7.1 and 7.5 hours per night
Average value = LCI + UCI /2 = 7.1 + 7.5 / 2
= 7.3hours per night, so we are 95% confident that it's somewhere between 7.1 and 7.5 hours per night which is eventually 7.3hrs per night.

A because 2(1)/(5) is less than 2(3)/(5).
