Explanation:
_____________________________________
From the stem-and-leaf plot provided, we can write the following values from the data set, from least to greatest:
____________________________________
{15, 18, 46, 50, 50, 50, 50, 57} ;
____________________________________
To calculate the mean, we take the sum of all the values in the data set; that is, we add up all the values in the data set; and we divide that sum total by the number of values in the data set.
In our data set, we have EIGHT (8) values.
To calculate the mean:
_________________________
{15 + 18 + 46 + 50 + 50 + 50 + 50 + 57} / 8 = the mean {our answer}.
________________________________________________________
→ {15 + 18 + 46 + 50 + 50 + 50 + 50 + 57} / 8 =
→ {336} / 8 = 42 .

The answer is: " 42 " .

Answer: sorry I don’t understand the question
Step-by-step explanation:
1. Check all polynomials that are perfect square trinomials:9x2 − 6x + 1
16x2 + 24x + 9
2. Factor completely: x2 − 8x + 16
(x − 4)(x − 4)
3. Factor completely: 16x2 + 40x + 25
(4x + 5)(4x + 5)
4. Rhett decides to build a square room for his movie and music collection. If the area of the room is 9x^2 − 6x + 1 square feet, what is the length of one side of the room?
(3x − 1) feet
5. Given the following perfect square trinomial, fill in the missing term. (Do not type the variable in the blank.)
