1. Given the lengths: <span>3, 4, 5, 5, 6, 7, 8, 9, 10 The median of the data, will be the middle number. From the data shown the middle number is: B] 6
2. The mean is more affected by outliers since it takes into account all the values in a given set of data. Thus existence of outliers will greatly affect the mean. Hence the correct answer is A]
3. Given the math test scores of Mrs. Hunter's class, the range is given by: Range=(maximum value)-(minimum value) thus: Maximum value=100 Minimum value=48 therefore plugging in the formula: Range=100-48=52 Answer: B]
4. From the given heights of 13 plants: </span><span>6, 9, 10, 10, 10, 11, 11, 12, 12, 13, 14, 16,17. </span>The IQR is given by: IQR=(upper quartile)-(lower quartile) upper quartile=(14+13)/2=13.5 lower quartile=(10+10)/2=10 thus IQR=13.5-10=3.5 Answer: A]3.5
To figure out the cost for 180 packages, you must first calculate how many packages they bought for $72. Since each case holds 12 packages, for $72, the company bought 24 packages (12×2). Then you have to divide 24 into 180 to figure out the cost for those 180 packages and get 7.5. To get the cost of the 180 packages, you must multiply 7.5 (the number of 24 packages that go into 180) by 72 (the cost of one group of 24 packages). You then get 540. The company must pay $540 for the 180 packages.
for 8, it's 6 squared plus 9 squared, which is 117. now, 15 squared is 225. 225 is bigger than 117, which makes it obtuse. if the two results equaled each other, it would be a right triangle. if the 2 smaller numbers when squared were bigger than the hypotenuse squared, then it would be acute
