Parallel Lines Cut by a Transversal: Maze

CaHeK987 [17]

Start from Start Here square, the pointer to the next question to resolve is given by the solution to the equation in the current square

The values of the Maze are as follows;

x = 10
x = 8
x = -9
x = 5
x = 11
x = 3
x = -5
x = 9
x = 7
x = -7

Reason:

The solutions are;

10·x + 15 = 12·x - 5 by alternate interior angles theorem

∴ x = 10

6·x + 6 = 5·x + 14 by alternate exterior angles theorem

∴ x = 8

x + 109 = 100 by corresponding angles theorem

∴ x = -9

11·x + 5 + 120° = 180° by same side interior angles theorem

∴ x = 5

11·x - 1 = 10·x + 10 by corresponding angles theorem

∴ x = 11

35·x + 5 = 110 by corresponding angles theorem

∴ x = 3

x + 85 + x + 105 = 180 by same side interior angles theorem

∴ x = -5

7·x - 3 + 12·x + 12 = 180° by same side interior angles theorem

∴ x = 9

19·x - 3 = 130 by alternate interior angles theorem

∴ x = 7

x + 67 = 60 by alternate interior angles theorem

x = -7

Suppose that in a random sample of size 200, standard deviation of the sampling distribution of the sample mean 0.08. researcher

sertanlavr [38]

Answer:

400

Step-by-step explanation:

The computation of the sample size needed is shown below:

Since at the sample size of 200 there is a standard deviation of 0.08

But when the standard deviation is 0.04 so the sample size is 400

As sample standard deviation would be inversely proportional to the square root of the sample size

Find all solutions of the given system of equations (If the system is infinite many solution, express your answer in terms of x)

lisov135 [29]

Answer:

(a) The system of the equations $\left \{ {2x-3y\:=3} \atop {4x-6y\:=3}} \right.$ has no solution.

(b) The system of the equations $\left \{ {4x-6y\:=10} \atop {16x-24y\:=40}} \right.$ has many solutions $y=\frac{2x}{3}-\frac{5}{3}$

Step-by-step explanation:

(a) To find the solutions of the following system of equations $\left \{ {2x-3y\:=3} \atop {4x-6y\:=3}} \right.$ you must:

Multiply $2x-3y=3$ by 2:

$\begin{bmatrix}4x-6y=6\\ 4x-6y=3\end{bmatrix}$

Subtract the equations

$4x-6y=3\\-\\4x-6y=6\\------\\0=-3$

0 = -3 is false, therefore the system of the equations has no solution.

(b) To find the solutions of the system $\left \{ {4x-6y\:=10} \atop {16x-24y\:=40}} \right.$ you must:

Isolate x for $4x-6y=10$

$x=\frac{5+3y}{2}$

Substitute $x=\frac{5+3y}{2}$ into the second equation

$16\cdot \frac{5+3y}{2}-24y=40\\8\left(3y+5\right)-24y=40\\24y+40-24y=40\\40=40$

The system has many solutions.

Isolate y for $4x-6y=10$

$y=\frac{2x}{3}-\frac{5}{3}$
