Answer:
18 gallons
Step-by-step explanation:
divide 300 by 15 you 150 or 15 again then add 1 gallon per every twenty miles
thus your answer is 18 gallons of gas
Answer: -6 is your answer
M<K and m<M should be the same size, and m<L and m<N should also be the same size as each other. I would go with C.
Answer:
The upper 20% of the weighs are weights of at least X, which is , in which is the standard deviation of all weights and is the mean.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Upper 20% of weights:
The upper 20% of the weighs are weighs of at least X, which is found when Z has a p-value of 0.8. So X when Z = 0.84. Then
The upper 20% of the weighs are weights of at least X, which is , in which is the standard deviation of all weights and is the mean.
