Answer:

D) a 360° clockwise rotation about the center of the parallelogram will take the parallelogram <em>PQRS </em> onto itself.

Step-by-step explanation:

The parallelogram <em>PQRS </em>is in quadrant III (3) of the coordinate plane.  If the image is reflected over the line x = -5 or y = -5, it would be the mirror image of itself and would move either left (x = -5) or down (y = -5) over the lines.  A 180°  rotation about the center of the parallelogram would move the object to quadrant I (1).  However, a 360° clockwise rotation about the center of the parallelogram would cause the object to make a full circle and take the  parallelogram <em>PQRS </em> onto itself.

When number is multiplied by 4 subtracting from 68, the result obtained is the same as three times the sum of the number and 4 f
Artemon [7]

Answer:

Let the no.be X

when multiplied by 4 = 4X

68-4X=3(X+4)

68-4X=3X+12

collecting like terms together,

7X=56

therefore; X=8

hence ,the number is 8.

A dumpling machine automatically inserts mixed vegetables and meat filled wontons into a plastic package. Past experience reveal
Tanya [424]

Answer:

c. 0.810

Step-by-step explanation:

Given, total % of satisfactory packages = 90% = 0.90

Now, since selecting a satisfactory package is independent of any other trials (i.e. all the selection trials are independent to each other)

Hence, Probability of selecting two packages that re satisfactory

P(Selecting 2 satisfactory packages) = (0.90)^2

P(Selecting 2 satisfactory packages) = 0.90*0.90

P(Selecting 2 satisfactory packages) = 0.810

Note: We are selecting product since the chance of selecting in each trials are independent.
