Number of bikers: b
miles ridden by each biker: 50
number of miles ridden by the team: 50b
Condition: 50b ≥ 560
=> b ≥ 560 / 50
=> b ≥ 11,2
Given that b refers no number of persons it has to b an integer and b has to be at least 12
=> b ≥ 12.
If there would be 11 bikers the team only could complete 11*50 = 550 miles, so they cannot complete the required 560 miles.
Answer: b ≥ 12
Answer:
The total amount repayable will be £8,280.24.
Step-by-step explanation:
Use the attached formula
Answer:
The correct statement is:
On average, the height of a garden gnome varies 3.2 inches from the mean of 6 inches.
Step-by-step explanation:
We are given a data of 11 gardens as:
2 9 1 23 3 7 10 2 10 9 7
Now on removing the outlier i.e. 23 (since it is the very large value as compared to other data points) the entries are as follows:
x |x-x'|
2 4
9 3
1 5
3 3
7 1
10 4
2 4
10 4
9 3
7 1
Now mean of the data is denoted by x' and is calculated as:
Hence, Mean(x')=6
Now,
∑ |x-x'|=32
Now mean of the absolute deviation is:

This means that , On average, the height of a garden gnome varies 3.2 inches from the mean of 6 inches.
Let call it x
x/4=4/2
->x=8
It is helpful to estimate quotients when the number is very big.
