What set of reflections and rotations would carry rectangle abc do onto itself

1 answer:

3 0

The correct answer for this question is "reflect over the y-axis, reflect over the x-axis, rotate 180°." In order to get to the expected transformation, first, flip it over the y-axis which cost 90 degrees of rotation. Then lastly, flip shape from 2nd quadrant over the y-axis. It will now be coincide with the transformation at the 3rd quadrant. Could I be brainlest... I'm a middle schooler who did this so...

Please help @musiclover10045 I have been stuck on this problem like forever

a) ABD and CBD are Supplementary angles and need to equal 180 degrees

Subtract 117 from 180 for CBD:

CBD = 180 - 117 = 63 degrees

b) In triangles the the shortest side would be opposite the shortest angle.

Since angle D is 56 degrees ( the smallest inside angle) then side BC would be the shortest side.

c) The side opposite the largest angle would be the longest.

Angle B is 63 degrees ( the largest) so side CD is the longest.

Question

Suppose that a committee is studying whether or not there is excessive time waste in our judicial system. It is interested in the mean amount of time individuals spend at the courthouse waiting to be called for jury duty. The committee randomly surveyed 81 people who recently served as jurors. The sample mean wait time was 4 hours with a sample standard deviation of 1.2 hours. Define the random variables X and $\bar{X}$ in words.

Answer:

(B)

X is the amount of time an individual waits at the courthouse to be called for service.
$\bar{X}$ is the mean wait time for a sample of individuals.

Step-by-step explanation:

The random variable X is the amount of time for which each of the prospective juror waits at the courthouse before being called for service.

$\bar{X}$ is the mean wait time for a the given sample of individuals. In the case given,

Which equation is in slope-intercept form and represents a line with slope 0 through the point (2, 3)?

Westkost [7]

Y = mx + b
slope(m) = 0
(2,3)...x = 2 and y = 3
now u sub
3 = 0(2) + b
3 = b

equation is : y = 0x + 3...or just simply, y = 3
