Answer:
whats the question
Step-by-step explanation:
You can write 1/4 as a decimal, equivalent fraction, and a percent.
To change 1/4 into a decimal, divide the numerator by the denominator. You will get 0.25. To make 1/4 into a percent, multiply the decimal by 100 or just move the decimal two places to the right. The percent is 25%. To make 1/4 into another equivalent fraction, multiply the numerator and denominator by the same number. For example, you can multiply the numerator by 2 and the denominator by 2. So, another equivalent fraction for 1/4 is 2/8.
Hope it helps :)

Answer:
0.99865
Step-by-step explanation:
The question above is modelled by gaussian distribution. Gaussian distribution is also known as Normal distribution.
To solve the above question, we would be using the z score formula
The formula for calculating a z-score
z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
In the above question,
x is 115 liters
μ is 100
σ is the population standard deviation is unknown. But we were given variance in the question.
Standard deviation = √Variance
Variance = 9
Hence, Standard deviation = √9 = 3
We go ahead to calculate our z score
z = (x-μ)/σ
z = (115 - 100) / 3
z = 15/ 3
z score = 5
Using the z score table of normal distribution to find the Probability of having a z score of 5
P(x = 115) = P(z = 5) =
0.99865
Therefore the probability that this year it will produce 115 liters of wine = 0.99865
