The domain and range is [-4, 4] and [0, 4]
<h3 /><h3>What is Domain and range?</h3>
The domain of a function is the set of values that we are allowed to plug into our function.
The range of a function is the set of values that the function assumes.
x² + y² = 16
y = √16 - x²
For domain under root should not be negative quantity,
16 - x²≥0
16≥x²
So, x≤4 or x≥4
Thus, the domain is [-4, 4]
Range:
y is maximum at x=0, y=4
y is minimum at x=4, y=0
Thus, range = [0, 4]

Answer:
58.29 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A =
h (a + b) , substitute given values into formula
A =
× 6.7 × (7 + 10.4)
= 3.35 × 17.4
= 58.29 cm²
Answer:
11
Step-by-step explanation:
The focal length is 14, and thus the sum of the lengths of the blue and red segments is also 14.
Answer:

And replacing we got:

And for this case the standard error assuming normality would be given by:

And replacing we got:

Step-by-step explanation:
For this problem we know the following notation:
represent the sample size selected
represent the number of airplane travelers who after a flight would fly that airline again
The estimated proportion for this case would be:

And replacing we got:

And for this case the standard error assuming normality would be given by:

And replacing we got:
