<h2>Answer:</h2>

The average distance each data value in the set is from the mean is:

                                    2.8

<h2>Step-by-step explanation:</h2>

We are asked to find the Mean absolute deviation i.e. MAD of the data set.

The data set is:

2010,2002,2005,2007,2001

Mean of the data is:

Mean=\dfrac{2001+2002+2005+2007+2010}{5}\\\\\\Mean=\dfrac{2025}{5}\\\\\\Mean=2005

Now, the absolute difference is:

|2010-2005|=5\\\\|2002-2005|=3\\\\|2005-2005|=0\\\\|2007-2010|=3\\\\|2001-2005|=4

Now, the mean of these absolute deviation i.e. MAD is:

MAD=\dfrac{5+3+0+2+4}{5}\\\\\\MAD=\dfrac{14}{5}\\\\\\MAD=2.8

              Hence, the answer is:

                      2.8

Which angles below are complementary?
tigry1 [53]

9514 1404 393

Answer:

  ∠KXN and ∠QXT

Step-by-step explanation:

The measure of each angle is the difference of the scale values that the rays intercept. (The same scale needs to be used for each ray.) Of course, complementary angles have a sum of 90°.

Here, we'll refer to angle aXb as "ab".

  NP = 95 -35 = 60

  PQ = 35 -20 = 15  . . .  not complementary to NP

__

  KN = 165 -95 = 70

  QT = 20 -0 = 20  . . .  complementary to KN   ⇒ your answer

__

  JK = 180 -165 = 15

  PQ = 35 -20 = 15  . . . not complementary to JK

__

  JK = 15

  NK = KN = 70  . . .  not complementary to JK

Degree of the polynomial (2x^3)-(x^2+11) .
WARRIOR [948]

First, distribute the terms.

1(2x^3) = 2x^3

-1(x^2+11) = -x^2-11

Standard form:

2x^3 - x^2 - 11

Since there is a 3, the degree of polynomial is cubic.

Suppose the x intercept of the graph of y=f(x) are 2 and 3. what are the x-intercepts of y=8f(x)
Yuliya22 [10]

We are given: Function y=f(x).

First x-intercept of the y=f(x) is 2.

x-intercept is a point on x-axis, where y=0.

Replacing y by 0 and x by 2 in above function, we get

0=f(2)

Second x-intercept of the y=f(x) is 3.

Replacing y by 0 and x by 2 in above function, we get

0=f(3)

We are given another function y=8f(x).

Here only function f(x) is being multiplied with 8.

That is y values of function should be multiply by 8.

Because we have y value equals 0. On multiplying 8 by 0 gives 0 again and it would not effect the values of x's.

Therefore,

x-intercepts of y=8f(x) would remain same, that is 2 and 3.

Help pls look at the picture
Alika [10]

Answer:

Option A: -\frac{4}{3} is the correct answer.

Step-by-step explanation:

Given that:

Slope of the line = \frac{3}{4}

Let,

m be the slope of the line perpendicular to the line with slope \frac{3}{4}

We know that,

The product of slopes of two perpendicular lines is equals to -1.

Therefore,

\frac{3}{4}.m=-1\\

Multiplying both sides by \frac{4}{3}

\frac{4}{3}*\frac{3}{4}m=-1*\frac{4}{3}\\

m = -\frac{4}{3}

-\frac{4}{3} is the slope of the line perpendicular to the line having slope \frac{3}{4}

Hence,

Option A: -\frac{4}{3} is the correct answer.
