Answer:

b) The yellow rectangle was translated right 5 units and reflected over the x-axis.

d) The yellow rectangle was translated right 5 units and up 3 units.

Step-by-step explanation:

Translation in geometry describes a function that moves an object a certain distance without altering it. The object is not rotated, reflected or re-sized after translation. Every point of the object is moved in the same direction through the same distance.

Reflection is a rigid transformation in which the given object is flipped across a line to create its image. Each point of the image maintains their distance from the line as in the object. In reflection, every point of the object changes initial location.

The options that describe the transformation are: The yellow rectangle was translated right 5 units and reflected over the x-axis, and the yellow rectangle was translated right 5 units and up 3 units.

Restless Leg Syndrome and Fibromyalgia

Anna11 [10]

Answer:

The probability that a person with restless leg syndrome has fibromyalgia is 0.183.

Step-by-step explanation:

Denote the events as follows:

F = a person with fibromyalgia

R = a person having restless leg syndrome

The information provided is as follows:

P (R | F) = 0.33

P (R | F') = 0.03

P (F) = 0.02

Consider the tree diagram attached below.

Compute the probability that a person with restless leg syndrome has fibromyalgia as follows:

$P(F|R)=\frac{P(R|F)P(F)}{P(R|F)P(F)+P(R|F')P(F')}$

$=\frac{(0.33\times 0.02)}{(0.33\times 0.02)+(0.03\times 0.98)}\\\\=\frac{0.0066}{0.0066+0.0294}\\\\=0.183333\\\\\approx 0.183$

Thus, the probability that a person with restless leg syndrome has fibromyalgia is 0.183.

Mario compared the slope of the function graphed below to the slope of the linear function that has an x-intercept of 1 and a y-

Lelu [443]

Answer:

The slope of the function graphed is less than the linear function that has an x-intercept of 1 and a y-intercept of -2.

Step-by-step explanation:

It is given that x-intercept is 1 and y-intercept is -2.

Now, the coordinate of the point is (1,0) and (0,-2).

We know that,

Slope = $\dfrac{y_2-y_1}{x_2-x_1}$

$S_1=\dfrac{-2-0}{0-1}$

$S_1 = \dfrac{-2}{-1}$

$S_1=2$

Now, Slope of the graph given

Co-ordinate is (-5,0) and (1,2).

Using the formula of slope

$S_2 = \dfrac{2-0}{1-(-1)}$

$S_2 = \dfrac{2}{1+1}$

$S_2 = \dfrac{2}{2}$

$S_2 =1$

Now, $S_1>S_2$

Hence, the slope of function graphed is less than linear function that has an x-intercept of 1 and a y-intercept of -2.

Bill is bisecting an angle with technology Which of the following describes his next step?

maw [93]

Answer:

Mark point E where the circle intersects segment BC

Step-by-step explanation:

Apparently, Bill is using "technology" to perform the same steps that he would use with compass and straightedge. Those steps involve finding a point equidistant from the rays BD and BC. That is generally done by finding the intersection point(s) of circles centered at D and "E", where "E" is the intersection point of the circle B with segment BC.

Bill's next step is to mark point E, so he can use it as the center of one of the circles just described.

___

Comment on Bill's "technology"

In the technology I would use for this purpose, the next step would be "select the angle bisector tool."

We know a or b != 0

but a-b==0 so both are the same unknown number

b/a must = 1

a/b is equivalent to b/a as a/b=1 as well.

So the last answer choice.
