Answer:
1/4
Step-by-step explanation:
Answer: A
Step-by-step explanation: when Constructing a confidence interval, it is important to take note of the margin of error which is given by the formulae below
Margin of error = critical value × σ/√n.
Where n is the sample size.
As we can see that the critical value is a constant and the population standard deviation.
Hence there is an inverse relationship between margin of error and sample size, which implies that a large sample size produces a small margin of error.
If the margin of error is small, it means the sample size will increase the like hood that the sample is a good representation of the population.
Answer:
Pentane
Explanation:
The plant grow 3.6 centimeter in 18 days and the student written it incorrectly as 1.44 days.
Division:
Division is the process of breaking a number up into equal parts, and finding out how many equal parts can be made. It is a reverse process of multiplication.
Given:
The ratio of growth for a plant is 0.2 centimeters per 0.5 day.
A student found the number of days for the plant to grow 3.6 centimeters to be 1.44 days.
Here we have to verify if the student is found the correct value or not.
For one day the plant grow 0.2 centimeter.
So, for 3.6 centimeter it will take
=> 3.6 / 0.2
=> 18
So, for 3.6 centimeter it will take 18 days.
So, here the student written it incorrectly as 1.44 days.

Answer:
1/36
Step-by-step explanation:
The probability that the first roll is a 2 is 1/6.
The probability that the second roll is a prime number is 3/6.
The probability that the third roll is more than 4 is 2/6.
The probability of all 3 is (1/6)(3/6)(2/6) = 1/36.
