Answer:

B. As coupon use increases, the amount of savings increases.

Step-by-step explanation:

We have been given a scatter plot and we are asked to choose the correct statement from our given choices.

We can see from our scatter plot that if we will draw a line of best fit, we can see that all the data points will be approximately equidistant from that line except some outliers.

We can also see that our given data trend has a positive relation as number of coupons are increasing, the amount of savings are also increasing.

Since the amount of savings increases with the increase in use of coupons, therefore, option B is the correct choice.

in the figure below trianglePQM and triangleQRP are right triangles. the measure of lineQM is 6 and the measure of lineQP is 8.
Kipish [7]

Answer:

Option 4 is correct. The length of PR is 6.4 units.

Step-by-step explanation:

From the given figure it is noticed that the triangle PQR and triangle MQR.

Let the length of PR be x.

Pythagoras formula

hypotenuse^2=base^2+perpendicular^2

Use pythagoras formula for triangle PQM.

PM^2=QM^2+PQ^2

PM^2=(6)^2+(8)^2

PM^2=36+64

PM^2=100

PM=10

The value of PM is 10. The length of PR is x, so the length of MR is (10-x).

Use pythagoras formula for triangle PQR.

PQ^2=QR^2+PR^2

(8)^2=QR^2+x^2

64-x^2=QR^2                   .....(1)

Use pythagoras formula for triangle MQR.

MQ^2=QR^2+MR^2

(6)^2=QR^2+(10-x)^2

36=QR^2+x^2-20x+100

36-x^2+20x-100=QR^2        .... (2)

From equation (1) and (2) we get

36-x^2+20x-100=64-x^2

20x-64=64

20x=128

x=6.4

Therefore length of PR is 6.4 units and option 4 is correct.

Which system about this figure is true?
jok3333 [9.3K]

Answer:

1) It has rotational symmetry with an angle of rotation of 90 degrees.

  TRUE, it has rotational degree, FALSE, angle of rotation is 180 degrees

2)It has no reflection symmetry.  FALSE

3)It has reflection symmetry with many planes of symmetry. TRUE

4)  It has no rotational symmetry. FALSE

Step-by-step explanation:

Rotational Symmetry is when an object is rotated around a center point (turned) a number of degrees and the object appear the same.

Symmetry Order = Number of turns it takes to get to its similar position.

Reflected Symmetry : When a line is drawn which divides the shape in to two equal halves it is called reflective symmetry.

Consider the given figure:

1) It has rotational symmetry with an angle of rotation of 90 degrees.

  TRUE, it has rotational degree.

FALSE,  it regains its identical shape in 90 degrees, it is in  180 degrees.

2)It has no reflection symmetry.

FALSE, the given figure has reflection symmetry along both horizontal and vertical axis.

3)It has reflection symmetry with many planes of symmetry.

TRUE, it has inflectional symmetry in Horizontal as well a in vertical plane.

4)  It has no rotational symmetry.

FALSE, it has a rotational  symmetry of ORDER 2
