Answer:
2.5%
Step-by-step explanation:
The percentage of people taking the test who are above 698 is ___%
Empirical rule formula states:
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ
From the question, we have:
Mean of 514 and a Standard deviation of 92
Hence:
μ ± xσ
514 ± 92x = 698
514 + 92x = 698
92x = 698 - 514
92x = 184
x = 184/92
x = 2
Hence, the data is correct and it is 2 standard deviation from the mean. Therefore, 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
The question is asking us to find the percentage of people taking the test who are above 698 is calculated as:
100 - 95% /2
= 5/2
= 2.5%
The percentage of people taking the test who are above 698 is 2.5%
Answer: 13 & 1/2 cups of sugar
Whole part = 13
Fractional part = 1/2
===================================================
Explanation:
4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5
1 batch = 3 cups sugar
4.5*(1 batch) = 4.5*(3 cups sugar)
4.5 batches = 13.5 cups of sugar
The decimal number 13.5 converts to the mixed number 13 & 1/2 which is the same as writing 13 1/2
