Base on the question where as asking what point would be the center or the rotation if the triangle is rotated 180 degree and the pre image should touch the original image more that ones, base on that, the possible answers would be point D, E and F, if they are in the center of the triangle

Can someone help me out

12345 [234]

Answer:

g - 16 is the answer

Step-by-step explanation:

−2 (3g−8g+8) − 9g

Distribute:

= (−2) (3g) + (−2) (−8g) + (−2) (8) + −9g

= −6g + 16g + −16 + − 9g

Combine Like Terms:

=−6g + 16g+ −16+ −9g

= (−6g+16g+−9g) + (−16)

=g+−16

Answer:

=g−16

A researcher conducted an Internet survey of 500 students at a particular college to estimate the average amount of money studen

bonufazy [111]

Answer:

The margin of error is $ME = 2.2962$

Step-by-step explanation:

From the question we are told that

The number of student is $n = 500$

The highest amount is $A =$ $200

The lowest amount is $B =$ $75

The sample mean is $x =$ &140

The Standard deviation of this set is mathematically evaluated as

$s = \frac{A-B}{4}$

Substituting values

$s = \frac{200-75}{4}$

$s = 31.25$

The margin of error (ME) is mathematically evaluated as

$ME = t_{n-1}__{\alpha }} * \frac{s}{\sqrt{n} }$

Where $t_{n-1}__{\alpha }}$ is the critical value for $\alpha = 0.05$ i.e the significance level

From the critical value table this is $t_{n-1}__{\alpha }} = 1.649$

So

$ME = 1.649 * \frac{31.25}{\sqrt{500} }$

$ME = 2.2962$

Step-by-step explanation:

$\frac{\pi}{2} = 90$

its 1/4 of the circle

circle circumference:

$8 \times \pi$

we need 1/4 of it, so its

$2 \times \pi = 6.28$
