In a basket, 5/9 of the fruits are apples and the rest are oranges. 3/10 of the apples are green in colour. There are 15 green apples. How many fruits are there in the basket?
Answer: 478
Step-by-step explanation:
The formula to calculate the standard error of the population mean is given by :-
, where
is the standard deviation and 'n' is the sample size.
Given: Mean : 
Standard deviation : 
Sample size : 
Now, the value of the standard error of the average annual salary is given by :-

Hence, the standard error of the average annual salary = 478
For this case we must propose an algebraic expression associated with:
"four times a difference of a number and seven is 12"
So we have to:
Four times a difference of a number and seven is represented as: 
So we have the expression is:

We apply distributive property to the terms within parentheses:

We add 28 to both sides:

We divide between 4 on both sides:
