Find the mean, median, mode, and range of these numbers 75,95,90,95,60,95,75,95,90

Mean=85.56, median=90, mode=95 and range=35

Step-by-step explanation:

To calculate the mean is the same as the average value in a data set. Median is data value separating the upper half of a data set from the lower half. The median is the data value separating the upper half of a data set from the lower half. The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number from the largest number.

answer: t=3

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
