Knowing that you need a sample pool of 1019 students to ultimately get about 500 students in your sample, you are in a position
Allushta [10]

Answer:

Sampling interval = 9.323

Step-by-step explanation:

Given that:

Population size, N = 9500

Require sample, n = 1019

Sampling interval :

Population size / required sample size

Sampling interval = 9500 / 1019 = 9.3228

Interpretation :

In other to obtain a sample of 1019 drawn systematically from the population, a sample will be drawn at every 9.323 units from the population of 9500

I need help with these 4 questions on my math homework! I have some examples with it but I still don't know how to do them... (S
lesya [120]

Step-by-step explanation:

For equation N°2

-x-3 = 0\\

Solving algebraically:

-x + x -3 = x (Sum x on both sides of the equation)

-3 = x\\


Resolving graphically:

x = -2 --------- - (- 2) -3 = -1 pto (-2, -1)

x = -4 ---------- - (- 4) -3 = 1 pt (-4.1)

x = -3 --------- - (- 3) -3 = 0 pt (-3.0) Solution

The graphic is shown in the attached image. The red dot in the graph represents the solution


For equation N° 4

9x +3 = 0\\

Solving algebraically:

9x+3 -3 = -3 (Sum -3 on both sides of the equation)

9x =-3


\frac{9x}{9}=\frac{-3}{9} (divided by 9 on both sides of the equation)

x =\frac{-3}{9} (simplifies the fraction)

x =\frac{-1}{3}


Resolving graphically:

x = 1 --------- 9 (1) +3 = 12 pt (1.12)

x = -1 --------- 9 (-1) +3 = -6 pto (-1, -6)

x = -1 / 3 -------- 9 (-1/3) +3 = 1 pt (-1 / 3.0) Solution

The graphic is shown in the attached image. The red dot in the graph represents the solution


For equation N°. 6.

4x + 11 = 4x-24\\

Solving algebraically:

4x -4x +11 = 4x -4x-24 (Sum -4x on both sides of the equation)

11 = -24 The equation is not met, the x are eliminated, therefore, it has solution


For equation N°. 8

-6x +3 = -6x + 5\\

Solving algebraically:

-6x + 6x +3 = -6x + 6x +5 (Sum 6x on both sides of the equation)

3 = 5 The x are eliminated, 3 is not equal to 5, the equality is not met. The equation has no solution.
