I would say that x is not equal to 1
This is the concept of algebra, given that the area of a rectangular pool is (15x-9), the possible dimensions of the pool by factoring will be:
Area=length×width
Area=(15x-9)
factoring the above we get:
Area=3(5x-3)
therefore the possible dimension will be:
length=5x units
width=3 units
Answer:
<h2>
2/81</h2>
Step-by-step explanation:
Probability is defines as the likelihood or chance that an event will occur.
Probability = expected outcome of event/total outcome.
Since a single die with 9 sides was rolled, the total event outcome will be 9*9 = 81
Expected outcome will be the event that the sum of the two rolls equals 3. The possible outcomes are {(1,2), (2,1)}. The expected outcome is 2
Probability that the sum of the two rolls equals 3 = 2/81
Answer:
Statistical inference refers to using a sample of measurements and making generalizations about the important aspects of a population.
Step-by-step explanation:
Statistical inference:
- Statistical inference is use of statistics to draw conclusions about some unknown parameters of a population based on a random sample from that population.
- With the help of sample statistic of a sample drawn randomly from the population, we approximate some properties of population.
- This is known as statistical inferences.
- It is an important method to analyze properties of a population based on the sample.
