Answer:
base: 4 units; height: 3 units
Step-by-step explanation:
It is easy enough to count the grid squares to see how many units long each side is. Similarly, the distance from the point to the base can be counted on the graph.
The square pyramid has a base that is 4 units on each side. The height of each triangular face is 3 units.
Answer:
0.7755
Step-by-step explanation:
If 120 CDs are defective, the number of non-defective CDs in the batch is:
![n=1950-120\\n=1830](https://tex.z-dn.net/?f=n%3D1950-120%5C%5Cn%3D1830)
In order for the batch to be accepted, all of the 4 CDs in the sample must not be defective, the probability of that happening is:
![P=\frac{1830}{1950}*\frac{1829}{1949} *\frac{1828}{1948} *\frac{1827}{1947}\\P=0.7755](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B1830%7D%7B1950%7D%2A%5Cfrac%7B1829%7D%7B1949%7D%20%2A%5Cfrac%7B1828%7D%7B1948%7D%20%2A%5Cfrac%7B1827%7D%7B1947%7D%5C%5CP%3D0.7755)
The probability that the entire batch will be accepted is 0.7755.
