Answer:
One-sample Z-test
Step-by-step explanation:
As the sample size is greater than 30, assuming the data is a simple random sample, and that the data has a normal distribution, the sociologist should conduct a one-sample z-test to calculate the p-value.
Answer:
Add both of the function together.
Step-by-step explanation:
s(x) + a(x) = 450 + 6(x - 2)

Answer:
<h3>
The answer is <u><em>
four</em></u>
.</h3>
Step-by-step explanation:
Each family gets four kilograms of apples because 16 divided by 4 is four. To show this, you can get 16 dots, draw 4 circles and add a dot into each circle representing 1 kilogram, once you've run out of dots in each circle, you will see the total of 4 dots in each circle.
The area of the square as a function of radius is given as A(r) = 2r^2
As given in the question a square is inscribed in a b. So the diagonals of the square will be the diameter of the circle.
The formula for the diagonals of the square is,
D = s√2
Where, s = side of the square
And the formula for the diameter of the circle is,
D = 2r
Where r = radius of the circle
As, Diagonals of the square = Diameter of the circle
Thus, s√2 = 2r
s = 2r/√2
s = r√2 (1)
Now, the formula of the area of the square is,
A = s^2
Putting the value of s from equation (1) in the above formula we get
A = (r√2)^2
A = 2r^2
Hence the area of the square as a function of radius is given as A(r) = 2r^2
