Step-by-step explanation:
t - 4t² + 2t³ = t(1 - 4t + 2t²)
= t(2t² - 4t +1)
≠≠≠≠ t(2t - 1)(t -1)
used a graphing calculator to find the roots
Find the mean of the following data set: 40, 58, 37, 23, 66, 42, 35, 37, 51, 42, 56, 37, 61, 52.

Answer:
45.5
Step-by-step explanation:
To find the mean is to find the average number of the data set.
In order to do this you add up all of the numbers, then divide it by the value how many numbers are in the set.
40+58+37+23+66+42+35+37+51+42+56+37+61+52= 637/14=45.5
