Answer:

- 2 ÷ 3 = - 0.667 and 3 ÷ (- 2) = - 1.5.

- 12 ÷ (- 4) = 3 and - 4 ÷ (- 12) = 0.333.

16 ÷ 8 = 2 and 8 ÷ 16 = 0.5.

Division is not commutative.

Step-by-step explanation:

We have to find the quotients in each group as given in the attachment.

- 2 ÷ 3 = - 0.667 and 3 ÷ (- 2) = - 1.5. So, - 2 ÷ 3 ≠ 3 ÷ (- 2)

- 12 ÷ (- 4) = 3 and - 4 ÷ (- 12) = 0.333. So, - 12 ÷ (- 4) ≠ - 4 ÷ (- 12)

Now, 16 ÷ 8 = 2 and 8 ÷ 16 = 0.5. So, 16 ÷ 8 ≠ 8 ÷ 16

From the above examples, we can say division is not commutative. (Answer)

A carpenter cuts the corners of a rectangle to make the trapezoid shown.

lozanna [386]

The value of x in the trapezoid is 11.

<h3>Properties of an isosceles trapezoid</h3>

The base angles are the same
The sum of opposite angles is 180° or supplementary.
The diagonals are the same in length.

Therefore, the angle 9x and 7x + 4 are supplementary.

Hence,

9x + 7x + 4 = 180

16x + 4 = 180

16x = 180 - 4

16x = 176

x = 176 / 16

x = 11

Answer:

We need a sample size of at least 101

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.99}{2} = 0.005$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.005 = 0.995$ , so $z = 2.575$

Now, find the margin of error M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

What sample size is needed to estimate the true average speed to within 2 mph at 99% confidence?

We need a sample of at least n.

n is found when M = 2. So

$M = z*\frac{\sigma}{\sqrt{n}}$

$2 = 2.575*\frac{7.8}{\sqrt{n}}$

$2\sqrt{n} = 2.575*7.8$

$\sqrt{n} = \frac{2.575*7.8}{2}$

$(\sqrt{n})^{2} = (\frac{2.575*7.8}{2})^{2}$

$n = 100.85$

Rounding up

We need a sample size of at least 101

Find the exact values of cos 3 pi/4 radians sin 3 pi/4 radians.

Liula [17]

If you consult the unit circle, you will see that:

$cos(\frac{3\pi}{4}) = -\frac{\sqrt{2}}{2}\\\\sin(\frac{3\pi}{4}) = \frac{\sqrt{2}}{2}$

3pi/4 in degrees is 3pi/4 * 180/pi = 3/4 * 180 = 135 degrees. And please refer to the attachment to how you can obtain the values above.

Now, lets multiply it together.

$-\frac{\sqrt{2}}{2} \cdot \frac{\sqrt{2}}{2} =\\\\-\frac{2}{4} =\\\\ \boxed{\bf{-\frac{1}{2}}}$

So, <span>cos(3pi/4)sin(3pi/4) = -1/2</span>
