Answer:
Angles on a straight line add up to 180°
Therefore, the interior angle D of the triangle = 180 - 150 = 30°
Draw a horizontal line of 8 cm - label DE.
Measure an angle of 30° from point D and draw a line.
Measure an angle of 90° from point E and draw a line.
These 2 lines will intersect at point F.
Erase the part of the lines that extend past the point of intersection.
The first thing you need to know is f is the greatest common factor
here they are asking you for 3x meaning you power ( ^) can't go greater than 3
here are two forms
5x^2+8x^3+1
another one
2z^3-y^2+6
hope this helps
This is a quadratic equation with a general equation of ax^2 + bx + c.
The quadratic formula can help to get the roots of the equation. We know the highest degree of that equation is 2; so there will be also two roots.
The quadratic formula is
x = [-b ± √(b^2 - 4ac)] / 2a
With a = 1, b = 7, c = 2,
x = {-7 ± √[(7)^2 - 4(1)(2)]} / 2(1) = (-7 ± √41) / 2
So the two roots are
x1 = (-7 + √41) / 2 = -0.2984
x2 = (-7 - √41) / 2 = 0.2984
This is also another way of factorizing the equation
(x + 0.2984)(x + 0.2984) = x^2 + 7x + 2
Answer:
The answer is "Option a, Option b, and Option d".
Step-by-step explanation:
In the given question it is used to stratifying the sampling if the population of this scenario it flights takes off when it is divided via some strata.
-
In option a, In this case, it stratified the sampling, as the population of planes taking off has been divided into the days of the week.
-
In option b, It also used as the case of stratified sampling.
-
In options c, it is systematic sampling, that's why it is wrong.
-
In option d, It is an example of stratifying the sampling.
