Answer:
Sam gets £30 and Bethan gets £24.
Why?
When dealing with ratios, add up the numbers in the ratio.
5 + 4 = 9
Now, divide the total amount of money by that number.
£54/9 = 6
Now you have the base rate. Multiply each quantity in the ratio by this number.
5*6 = 30
4*6 = 24
Now, the ratio is (in euro) 30:24. This means that Sam has £30 and Bethan has £24.
Check:
30 + 24 = 54
It would be 2 6/7
the reason why it is right because i am so smart and i am in school...
I’m pretty sure that’s probably a nickel
4 sqrt(400) / 4 sqrt(5)
sqrt(400) =20
4 *20
--------
4 sqrt(5)
the 4's on the top and bottom cancel
20
--------
sqrt(5)
I was taught never to leave a sqrt in the denominator
so you need to multiply by sqrt (5) in the numerator and the denominator
20* sqrt(5)
--------
sqrt(5)* sqrt(5)
20* sqrt(5)
--------
5
= 4 sqrt(5)
A. Mean
Mean = Total / How many numbers there are
City A- Add all the numbers:
4 + 3.5 + 5 + 5.5 + 4 + 2 = 24
There are 6 numbers.
24 / 6 = 4
Mean = 4 for City A
City B- Mean:
Add all the numbers:
5 + 6 + 3.5 + 5.5 + 4 + 6 = 30
There are 6 numbers.
30 / 6 = 5
Mean = 5 for City B
B. MAD(Don't know this part)
C. Median
City A- Median:
There are 2 middle numbers.
They are 5 and 5.5
5 + 5.5 = 10.5
10.5 / 2 = 5.25
Median = 5.25 for City A
City B- Median:
The 2 middle numbers are 3.5 and 5.5
3.5 + 5.5 = 9
9 / 2 = 4.5
Median = 4.5 for City B.
Answers:
a. The mean for City A is 4. The median for City B is 5.
b. Don't know MAD
c. The median for City A is 5.25. The median for City B is 4.5
Hope this helped☺☺
