Solution:
A plane is a two Dimensional figure.
The Intersection of two planes that do not coincide is always a line.
Consider two planes ,A and B, Following are the possibilities
1. They may be parallel to each other.→→→ No curve obtained
2. The planes A and B can Coincide with each other.→→→Intersection is a plane.
3. The planes A and B are intersecting.→→→→Intersection is a line.
Answer:
4m/s
Step-by-step explanation:
Velocity = ds/dt
= (change in displacement) ÷ (change in time)
= slope of the function
= 4
Let x = the unknown number to get x = 6
Answer:
n-5=2n+9
Step-by-step explanation:
Using sampling concepts, the population and the sample are given as follows:
d. population: 6,000 batches of 100 cards sample: every 100th batch.
<h3>What is sampling?</h3>
It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a <u>group containing elements of a population</u>. A sample has to be representative of the population, that is, it has to involve all segments of the population.
For example:
I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So I ask, lets say, 1000 randomly selected New York state residents whether they are Buffalo Bills fans, and then:
- The population is: All New York State residents.
- The sample is the 1000 randomly selected New York state residents.
Hence, in the situation described the population is the 6,000 batches of 100 cards, while the sample is every 100th batch, hence option d is correct.
