Answer: .28
Step-by-step explanation: First turn the mixed number into an improper fraction. so 3x2+1=7, 7 is the the top and the bottom stays the same (2) so it would now be 7/2 divided by 5 which would equal .28

Answer: Estimated the standard deviation α = 5.35
Step-by-step explanation:
According to Empirical rule, the largest value is approximately:
ц + 3α
And the smallest value is approximately:
ц + 3α
Based on the given figures in the question, we can say
ц + 3α = 140.6
ц - 3α = 108.5
Now subtracting these two; we have
ц + 3α - ( ц - 3α ) = 140.6 - 108.5
ц + 3α - ц + 3α = 32.1
6α = 32.1
α = 32.1 / 6
α = 5.35
Estimated the standard deviation α = 5.35
Answer: 6
Step-by-step explanation:
Since Pam has 4 yards of fabric and she needs 2/3 yards of fabric for each curtain, the number of curtains that Pam can make with the fabric she has will be the total yards of fabric that she has divided by the fabric needs for each curtain. This will be:
= 4 ÷ ⅔
= 4 × 3/2
= 6
Therefore, she will make 6 curtains
The ratio House blend/Organic Free Trade blend is the same and must remain the same.
So, the proportion is:

Where x is the unknown amount of the Organic Free Trade blend.
So, from the proportion, we have:

Answer: 156 pounds of Organic Free Trade blend
