Answer:
x=30
Step-by-step explanation:
Please note, that you have a flowchart helping you solve the task - the answer to "how to solve this quesiton" is literally given below the question.
They say that if you first divide x by 2, then add 8, you get 23.
That means that (going backwards) if you start with 23 and subtract 8, then multiply by 2, you get x.
23-8 = 15
15 * 2 = 30
x = 30.
The answer of this problem is 3+3+1
Answer:
Step-by-step explanation:
The empirical rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean. The empirical rule is further illustrated below
68% of data falls within the first standard deviation from the mean.
95% fall within two standard deviations.
99.7% fall within three standard deviations.
From the information given, the mean is 500 and the standard deviation is 100.
95% of the scores of students would fall within two standard deviations.
2 standard deviations = 2 × 100 = 200
500 - 200 = 300
500 + 200 = 700
Therefore, the probability that a randomly selected student math score is between 300 and 700 is
95%
