Step-by-step explanation:
The following prices for the same make and model used guitar for his work are :
$699.20,$700.30,$680.50,$700.30, and $800.25.
Mean of ungrouped data = sum of observations/total no of observations
For median, arrange the given data in ascending order.
$680.50, $699.20, $700.30, $700.30, $800.25
Median = middle value
Median = $700.30
The value that comes most often is called mode.
$700.30 comes two times. So, mode is $700.30
Hence, Mean = $716.11, median = $700.30 and mode = $700.30

Answer:
the angle between their paths is <em>100.8°</em>
Step-by-step explanation:
From the given information, you can construct a triangle, just like the one in the figure.
We will use the <em>Cosine Rule</em> which is:
c² = b² + a² - 2 b c cos(θ)
where
- c = 16 miles
- b = 8 miles
- a = 12 miles
Therefore,
2 b c cos(θ) = b² + a² - c²
cos(θ) = (b² + a² - c²) / 2 b c
θ = cos⁻¹( (b² + a² - c²) / (2 b c) )
θ = cos⁻¹( (8² + 12² - 16²) / 2(8)(16) )
<em>θ = 100.8°</em>
<em></em>
Therefore, the angle between their paths is <em>100.8°</em>
The domain for which the function is defined is given by:
D. .
The domain of a function is the set that contains all possible input values for the function.
A square root is only defined for non-negative values, hence:
.
.
The intersection of these two domains is , hence option D is correct.
