The interval of filled bags is at confidence interval of 95%.
At 95% confidence interval, Z=1.96 (from Z tables).
But,
Z= (x-mean)/sd => 1.96 = (x-450)/20 => x (upper limit)= 20*1.96+450489 bags
Lower limit or minimum number bags to avoid replace= 450-1.96*20 =411 bags
Answer: 3 pounds of apple pie
Step-by-step explanation:
If there are 8 pies and each one weighs 6 ounces, then we can multiply 6 and 8 to get a total of 48 ounces. Then we would convert ounces to pounds. 48 ounces is 3 pounds.
So to find the perimeter of a square, we must add all of the sides together.
We know that a square's sides are all equal in length and that a square has 4 sides. So that means we need to add 4.7 four times to get the perimeter.
4.7 + 4.7 + 4.7 + 4.7 = 18.8
So the perimeter of the square is 18.8 cm.
Hope I helped!
