Random sampling is when you select a random group of people for something.
Ex. Out of a population of 259,096 people, a random sample of 400 people are choosen.
Answer:
x = 40
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 30² = 50²
x² + 900 = 2500 ( subtract 900 from both sides )
x² = 1600 ( take the square root of both sides )
x =
= 40
It is C.8 lines just count how many lines the shape has
f(x) = (x- zero) * (x -zero)
f(x) = (x--2) (x-8)
f(x) = (x+2) (x-8)
if you need it multiplied out
f(x) = x^2 +2x -8x-16
f(x) = x^2 -6x-16
Answer:
1884 flowers
Step-by-step explanation:
Radius of the garden=150 ft
To determine the number of flowers needed to surround the circular garden, we first find the perimeter.

Since the flowers are spaced every 6 in, we need to convert from inch to feet because we cannot divide different units.
Now, 12 Inch =1 Feet
Therefore, 6 Inch =0.5 feet
To determine the number of flowers, we simply divide the perimeter by 0.5 ft.
Number of flowers=942/0.5
=1884 flowers
