Answer:
About 300 of every 1,000 cars assembled should have one or more defects
Step-by-step explanation:
From the sample of 100 cars, we can estimate the total number of defective cars, using a rule of three.
In this question:
For each 100 cars, 30 defective.
How many defective for 1000?
100 cars - 30 defective
1000 cars - x defective
![100x = 30*1000](https://tex.z-dn.net/?f=100x%20%3D%2030%2A1000)
Simplifying by 100
![x = 30*10](https://tex.z-dn.net/?f=x%20%3D%2030%2A10)
![x = 300](https://tex.z-dn.net/?f=x%20%3D%20300)
About 300 of every 1,000 cars assembled should have one or more defects
We are given the equation:
h = 22,000 – 480 t
where h is height . The plane will land when h = 0,
therefore:
0 = 22,000 – 480 t
480 t = 22,000
t = 45.83 minutes
<span>hence the plane will land after 45.83 minutes</span>
Answer:
You can make pancakes 15 times.
Step-by-step explanation:
Assuming you meant 2/3 cup and not 23! In that case the answer would be 15. Divide 10 by 2/3 to get there!
