Answer:

D. is used to reveal an underlying pattern in the data.

Step-by-step explanation:

Smoothing a time series is achieved when a computer uses some pre-programmed calculation methods to remove noise from large volumes of data. Smoothing helps a user detect patterns in a set of data, thus making it possible to make future predictions. For example, smoothing can be used in the prediction of the rise and fall of stock prices. This helps the traders to have an idea of what to expect in the cost of trading.

Although smoothing reveals the patterns in a set of data, it provides no explanation as to why it is so. It is left to the researcher to draw conclusions as to the reasons for the patterns.

For this question, we can use the same side interior angle theorem.

Angles 1 and 2 are same side interior angles, which means that they are the interior angles on the same side.

To find the angle measure of the angles, we can plug in the value we have.

A=6x+18

A=6(10)+18

A=60+18

A=78

B=9x+12

B=9(10)+12

B=90+12

B=102

To find if the oars are parallel, we can use the same side interior angle theorem, which states that if the same side interior angles are supplementary, the lines are parallel.

78+102=180

Seeing as the angles are supplementary, the oars are parallel to each other.

Hope this helps.

頑張って!

Joe has 4 less than 7 times as many shirts as Mark. Together, Joe and Mark have 140 shirts. How many shirts does Joe have? How m
lara [203]

Answer:

Mark has 18 shirts

Given that together they have 140 shirts.

x + 7x - 4 = 140

8x = 140 + 4

8x = 144

x = 144/8

x = 18

Joe has 122 shirts

7x - 4

7 × 18 - 4

126 - 4

= 122

Are these shapes congruent?
Vladimir [108]

Answer:

No

Step-by-step explanation:

In order for the shapes to be congruent, corresponding parts must be congruent.  The corresponding angles are NOT congruent, so the shapes are not congruent.

.Solve 2x−1<4 or −5x−3>−3 and write the solution in interval notation.
nevsk [136]

The interval notation is { 5/ 2 < x > 0 }

<h3>How to determine the value</h3>

Given the inequalities;

  • 2x−1<4
  • −5x−3>−3

To determine the value of x, we have;

2x - 1 < 4

collect like terms

2x < 4 + 1

2x < 5

Make 'x' the subject

x < 5/ 2

−5x −3 > −3

collect like terms

-5x > -3 + 3

-5x > 0

x > 0

Thus, the interval notation is { 5/ 2 < x > 0 }
