A cube is a square shape, so both sides ( length and width) of a face would be the same.
Find the length of the side by finding the square root of the area of the face:
Length = √400 = 20 cm.
Volume is Length x Width X height.
Volume = 20 x 20 x 20 = 8,000 cm^3
Answer:
oop lol i must be a rat then
Step-by-step explanation:
Answer: D. A single number calculated from the sample that estimates a target population parameter is called a point estimator.
An interval estimator is a range of numbers that contain the target parameter with a high degree of confidence.
Step-by-step explanation:
When we evaluate an range of values for an unknown population parameter, then it is known as interval estimation .
A single number evaluated from the SAMPLE that estimates an unknown population parameter is known as a point estimator.
The general difference between point and interval estimator is the point estimator is a single value of target parameter while interval estimator is a range of numbers to estimate the values about the unknown population.
