Step-by-step explanation:
Answer:
for sample = xbar
population = μ
Step-by-step explanation:
The arithmetic mean for sample can be represented by xbar and it can be calculated as
xbar=∑xi/n
Where xi represents data values and n represents number of data values in a sample.
The arithmetic mean for population can be represented by μ and it can be calculated as
μ=∑xi/N
Where xi represents data values and N represents number of data values in a population.
Answer:
1 cup of blue paint required 5 cups of yellow paints
<em />
Step-by-step explanation:
Given
2 cups of blue = 10 cups of yellow
Required
Determine the number of cups of yellow for 1 cup of blue paint
The given parameter shows a linear relationship between paints of blue and paints of yellow
We have:
2 cups of blue = 10 cups of yellow
Multiply both sides by 0.5
0.5* 2 cups of blue = 0.5* 10 cups of yellow
1 cup of blue = 5 cups of yellow
Hence;
<em>1 cup of blue paint required 5 cups of yellow paints</em>
