Answer:
x² - 6x + 9
Step-by-step explanation:
(x - 3)² = x² - 6x + 9
Answer:
cos(O) = 39 / 89
Step-by-step explanation:
Given:
ΔOPQ, where
∠Q=90°
PO = 89
OQ = 39
QP = 80
cosine of ∠O?
cos(O) = Adjacent / Hypotenuse
cos(O) = 39 / 89
Answer:
y = x/3 + 7
Step-by-step explanation:
Use the equation: y - y1 = m(x - x1)
Plug in the given values into the equation:
y - 5 = (1/3)(x + 6)
Simplify the right side:
y - 5 = (x/3) + 2
Finally, add 5 to both sides:
y = x/3 + 7
Answer:
20
Step-by-step explanation:
Answer:
Assuming population data
Assuming sample data
Step-by-step explanation:
For this case we have the following data given:
736.352, 736.363, 736.375, 736.324, 736.358, and 736.383.
The first step in order to calculate the standard deviation is calculate the mean.
Assuming population data
The value for the mean would be:
And the population variance would be given by:
And we got
And the deviation would be just the square root of the variance:
Assuming sample data
The value for the mean would be:
And the population variance would be given by:
And we got
And the deviation would be just the square root of the variance:
