A simple algebraic equation can be utilized to solve this question. Ayana needs yards of blue fabric for each scarf.
Step-by-step explanation:
Step 1; Assume the amount of purple fabric to be x for each scarf and the amount of blue fabric required for each scarf to be y. It says a total of six scarves are needed. It is given that a total of 10 yards of fabric is used i.e. the total of purple fabric and the blue fabric. So we can create an equation for this. As 6 scarves are needed we substitute x and y as 6x and 6y.
Total fabric used= 6x + 6y = 10 yards.
Step 2; It is given that for each and every scarf 1 yards of purple fabric is needed. So for 6 scarves a total of 6 * 1 yards is needed. So 6x becomes 6 * 1 yards.
6x = 6 * 1 yards = 6 * = yards of purple fabric.
Step 3; Now we solve for the amount of blue fabric needed.
6y = 10 - = =
But the yards is for 6 scarves to we divide it by 6 to get the material needed for a single scarf
y = /6 = * = = yards = 0.4166 yards of blue fabric for each scarf.
Answer:
0.3
Step-by-step explanation:
The margin of error is calculated as ...
(standard deviation)/√(sample size) × (z*-score)
where the z*-score is chosen based on the desired confidence level.
Here, you have ...
- standard deviation = 2.7
- √(sample size) = √225 = 15
- z*-score for 90% confidence level = 1.645
Putting these values in the above expression for margin of error gives ...
2.7/15·1.645 = 0.2961 ≈ 0.3

Number 2 depends because u might be lookin for the zeros or an intersection. If u lookin for the zeros u look at the x intercept.
