<span>if it is travelling 20 feet in 1/5 of a second that means that in 1 second (which is 5 times as much as 1/5 of a second) it will do 5 times 20 feet hence 100 feet. Then in 3 seconds it will do 300 feet</span>
Ax + z = aw - y
Ax + z - aw = -y
- Ax - z + aw = y <==
Given Two-thirds of the students in a class are wearing blue jeans
.Or
Of students wear blue Jeans.
Number of students wearing red shirts is Two-sixths of the students who are wearing blue jeans .
Number of students wearing red shirts = ![\frac{2}{6} of\frac{2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B6%7D%20of%5Cfrac%7B2%7D%7B3%7D%20%20%20)
Simplifying we have:
Fraction of the students in the class are wearing blue jeans red shirts =![\frac{2}{9}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B9%7D%20%20)
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%
