What is the value of x?

KiRa [710]

<h3>✽ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ✽</h3>

➷ Since vertical angles are equal, we know this:

3x + 50 = 6x - 10

Now we just need to solve for x.

Subtract 3x from both sides:

50 = 3x - 10

Add 10 to both sides:

60 = 3x

Divide both sides by 3:

x = 20

The area of a regular hexagon inscribed in a circle with radius 2 is . Round your answer to the nearest tenth.

Verdich [7]

Answer:

10.4 to nearest tenth.

Step-by-step explanation:

If we draw lines from the centre of the circle to each vertex of the hexagon we get 6 equilateral triangles of side length 2.

Altitude of each triangle = sqrt(2^2 - 1^2)

= sqrt3.

So the area of 1 triangle = 1/2 * 2 * sqrt3

= sqrt3

Therefore the area of the hexagon = 6 * sqrt3

= 6sqrt3

= 10.3923

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tail

aleksandrvk [35]

Answer: The hypothesis test is left-tailed test.

The parameter tested here is population mean.

Step-by-step explanation:

Given : The null and alternative hypotheses are as follows:

$H_0:\mu=6$

$H_1:\mu$

We can see that the parameter tested here is population mean.

Also, the type of test depends on the alternative hypothesis.

Since the alternative hypothesis is left-tailed so the hypothesis test is left-tailed test.
