Arandon sample of monthly gasoline bills for a company's 15 sales persons are: $216 $254 $247 $257 $231 $265 $221 $226 $228 $252 $235 $265 $272 $285 $266.what is the mean? what is the median? what is the value of quartile 3? what is the value of the modethe range is equal to? what is the value of the standard deviation? what is the value of the coefficient of variation? do not express the answer as a percent, leave it as a ratio? are the numbers skewed positively, negatively or are they symmetrical? (for your answer enter only one word: positively, negatively or symmetrical. what is the value of the coefficient of skewness using pearson's coefficient of skewness? what is the value of quartile 2?

Mean = $248

Median = $252

Quartile 3 = $265

Mode = $265

range = $69

Standard deviation= 20.126

Coefficient of variation = 8.115

Negatively

Coefficient of skewness = -0.596

Quartile 2 = $252

the correct answer is d

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
