Answer:
And based on this the best answer would be:
a. mean = 4; standard deviation = 2.68
Step-by-step explanation:
For this case we have the following data given:
1,5,8,5,1
We can find the sample mean with the following formula:
And replacing we got:
And for the deviation (assuming that the correct approximation is the deviation for a population) we can calculate the deviation with the following formula:
And replacing we got:
And based on this the best answer would be:
a. mean = 4; standard deviation = 2.68

Answer:
x = 11, y = 3
Step-by-step explanation:
(13x - 19) and (9x + 25) are corresponding angles and congruent, thus
13x - 19 = 9x + 25 ( subtract 9x from both sides )
4x - 19 = 25 ( add 19 to both sides )
4x = 44 ( divide both sides by 4 )
x = 11
Then
13x - 19 = 13(11) - 19 = 143 - 19 = 124
(17y + 5) and 124 are alternate angles and are supplementary, thus
17y + 5 + 124 = 180, that is
17y + 129 = 180 ( subtract 129 from both sides )
17y = 51 ( divide both sides by 17 )
y = 3
Answer:
y - 1 = 2(x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 2 and (a, b) = (- 2, 1), thus
y - 1 = 2(x - (- 2)), that is
y - 1 = 2(x + 2) ← in point- slope form
Answer
-3m + 17
Step-by-step explanation:
A coefficient is a number that goes in front of the variable, so -3 would go in front of m. A constant is just a number on it's own, so it would be +17
