Answer:
The mean of of the sample mean of these quality checks is 10 and the standard deviation is 0.7155.
Step-by-step explanation:
To solve this question, we use the central limit theorem.
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
In this problem, we have that:
The mean of of the sample mean of these quality checks is 10 and the standard deviation is 0.7155.
Answer:
Correct answer: r = 5%
Step-by-step explanation:
Given:
L = 4,500 Loan
t = 4 years time to repay
I = 900 Interest
r = ? simple interest rate
The formula for calculating simple interest is:
I = (L · r · t) / 100
r = ( I · 100) / L · t
r = (900 · 100) / 4,500 · 4 = 90,000 / 18,000 = 5 %
r = 5 %

Answer:
100:59
Step-by-step explanation:
For every pound a company spends on advertising, it spends £0.59 on its website.
Amount Spent on Advertising = £1
Amount Spent on Website = £0.59
Therefore:
Amount Spent on Advertising : Amount Spent on Website
= 1 : 0.59
Multiply both sides by 100
= 100: 59
The ratio of the amount spent on advertising to its website as a ratio in its simplest form is 100:59 in its simplest form.
