Given:
Julia and Rasheed are mixing yellow paint and blue paint to make green paint.
The mixture needs to be 60% blue paint and 40% yellow paint.
They need to make 3 gallons of the green paint.
Now, to find the quantity of yellow paint they should use.
As,
60% + 40% = 100%
So, we get the ratio of blue paint to yellow paint:
= 
= 
= 
Thus, the ratio of blue paint : yellow paint is 3:2.
<em>They need to make total 3 gallons of green paint.</em>

Answer: 
Step-by-step explanation:
Given : A random sample of 700 home owners in a particular city found 112 home owners who had a swimming pool in their backyard.
i.e. n= 700 and x= 112
Sample proportion : 
z-value for 95% confidence interval : 
Now, the 95% confidence interval for the true percent of home owners in this city who have a swimming pool in their backyard will be :-
Hence, 95% confidence interval for the true percent of home owners in this city who have a swimming pool in their backyard :
Answer:
c. Weight is input, height is output
Step-by-step explanation:
It is given here that "Height is a function of Weight".
which means
Thus, value of Height is depend on the value of Weight.
Thus, Weight is input variable and Height is output variable.
Hence option (c) is correct.
Further,
The variable that we can change is called the Input variable.
The Output variable depends upon the input variable, as we change the value of the input variable the value of the output variable is also get changed.
12.99+ 3.75x= total. therefore, 12.99+3.75(4)= 27.99
