Answer:

As both the standard deviation and the mean have the desired values, the tool passes the technical control.

Step-by-step explanation:

Mean:

The mean is the sum of all values divided by the number of values.

[tex]M = \frac{199+204+201+197+195+204+200}{7} = 200[/tex]

The mean is in the desired range.

Standard deviation:

The standard deviation is the square root of the sum of the difference squared between each value and the mean, divided by the number of values.

[tex]S = \sqrt{\frac{(199-200)^2+(204-200)^2+(201-200)^2+(197-200)^2+(195-200)^2+(204-200)^2+(200-200)^2}{7}} = 1.18[/tex]

As both the standard deviation and the mean have the desired values, the tool passes the technical control.

Answer:

It is not a polynomial function, because it includes a negative exponent.

Answer:

Step-by-step explanation:

Leading coefficient = 9

It is in standard form.

It is degree 4

It is a polynomial (I don't think there is a special name for degree 4). Time to eat crow. A 4th degree Polynomial is a quartic.

I didn't notice the power is -2. I am incorrect in telling you it was a polynomial (function). As I noted below, more crow to eat. Please give the Brainliest to the other responder

Answer:

(x + 5)^2 + (y + 1)^2 = 2^2

Step-by-step explanation:

I see that the instructions here call for "completing the square."

We need to rewrite x^2 + y^2 + 10x + 2y + 22 = 0 in the standard equation-of-a-circle formula (x - h)^2 + (y - k)^2 = r^2.

Start with x^2 + y^2 + 10x + 2y + 22 = 0,  Group x terms together, then y terms:

x^2 + 10x   + y^2 + 2y = -22

Going through the steps of completing the square, we insert additional constants:

x^2 + 10x + 25 - 25 + y^2 + 2y + 1 - 1 = -22, or

 x^2 + 10x + 25   + y^2 + 2y + 1 = + 25 + 1 - 22 = 4

Rewrite x^2 + 10x + 25 as (x + 5)^2, and y^2 + 2y + 1 as (y + 1)^2

after which the original equation becomes  (x + 5)^2 + (y + 1)^2 = 2^2

Answer: The pair of corresponding angles are ∠2 and ∠14 , ∠3 and ∠7 . Option (B) and (D) is correct . When two lines are parallel to each other and cross by another line i.e is called the Transversal , the angles lies in the matching corners are called corresponding angles.

hope it helps!!

From the options given, the angles that are pairs of corresponding angles given in the image are:

Corresponding angles will always lie on the same transversal and occupy the same relative position on the two different parallel lines that are intersected by the transversal.

Answer:

Option B

Step-by-step explanation:

Average rate of change of a function 'f' in the interval x = a and x = b is given by,

Average rate of change of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

Given function is,

g(x) = [tex]\frac{5}{x-1}+2[/tex]

We have to calculate the rate of change in the interval [-4, 3],

Average rate of change = [tex]\frac{g(3)-g(-4)}{3-(-4)}[/tex]

g(3) = [tex]\frac{5}{3-1}+1[/tex]

       = 2.5 + 1

       = 3.5

g(-4) = [tex]\frac{5}{-4-1}+1[/tex]

       = -1 + 1

       = 0

Average rate of change = [tex]\frac{3.5-0}{3+4}[/tex]

                                        = [tex]\frac{3.5}{7}[/tex]

                                        = [tex]\frac{1}{2}[/tex]

Therefore, Option B will be the answer.

Answer:

Step-by-step explanation:

1)

Given that:

The joint pmf  [tex]p_{X,Y(a,b)}=\left \{ {{\dfrac{1}{4a} \ for \ 1 \le b \le a \le 4 } \\ \\ \atop {0} \ \ \ \ \ \ otherwise} } \right.[/tex]

To emphasize that this is a joint pmf;

We will notice that it obeys two conditions;

Except that X and Y are integer value variables with 1 ≤ b ≤ a ≤ 4 and X = 1, 2, 3, 4 and Y = 1, 2, 3, 4 respectively, according to the condition Y ≤ X

The  table below shows the joint probabilities as a result of this:

              y = 1         y = 2        y = 1         y = 4          Total

x = 1          [tex]\dfrac{1}{4}[/tex]             0                0             0               [tex]\dfrac{1}{4}[/tex]

x = 2         [tex]\dfrac{1}{8}[/tex]             [tex]\dfrac{1}{8}[/tex]                 0             0               [tex]\dfrac{1}{4}[/tex]

x = 3        [tex]\dfrac{1}{12}[/tex]           [tex]\dfrac{1}{12}[/tex]               [tex]\dfrac{1}{12}[/tex]              0              [tex]\dfrac{1}{4}[/tex]  

x = 4        [tex]\dfrac{1}{16}[/tex]           [tex]\dfrac{1}{16}[/tex]               [tex]\dfrac{1}{16}[/tex]              [tex]\dfrac{1}{16}[/tex]             [tex]\dfrac{1}{4}[/tex]

Total       [tex]\dfrac{25}{48}[/tex]            [tex]\dfrac{13}{48}[/tex]             [tex]\dfrac{7}{48}[/tex]                 [tex]\dfrac{3}{48}[/tex]           1

In the table, it is obvious that each respective value of the probability is positive and the addition of all the values sums up to unity (1).

Hence, the given probability shows that it is indeed a pmf(probability mass function).

(b)

Marginal Pmf of x = [tex]\dfrac{sum \ of \ all \ prob. \ of (x,y)}{y}[/tex]

Marginal Pmf of y =  [tex]\dfrac{sum \ of \ all \ prob. \ of (x,y)}{x}[/tex]

Thus, we can locate the respective values of the marginal probability in the last row as well as the last column in the explained table above.

(c)

To find P(X=Y+1):

P(X = Y + 1) = P(X = 2,3,4)

⇒ 1 - P(X=1)

[tex]\implies 1 - \dfrac{1}{4} \\ \\ \implies \dfrac{4-1}{4} \\ \\ \implies \dfrac{3}{4}[/tex]

Step-by-step explanation:

The equation in vertex form is ...

  H(x) = 5(x^2 -2x) = 5(x^2 -2x +1) -5

  H(x) = 5(x -1)^2 -5

The only value of x that will make H(x) = -5, is x=1.

Answer:

Step-by-step explanation:

8x+9/x^2-13x+42

Write  8 x  as a fraction with denominator 1

8x+9/x^2-13x+42

then we multipuly 8x/1  by x^2/x^2

To Find Surface Area:

So Surface area is found according to this equation SA=2lw+2lh+2hw

6and 1/2 times 2 is 13 that would be the 2 sides

then you do 3 times 6 1/2 which is 19 1/2, which is the top and bottom

finally you do 3 times 9 1/5 which is 27 3/5.

Now since 1/2 and 1/5 are not the same, we find the LCM or Least Common Multiple, which is 10 so 1/2 is multiplied by 5 which is 5/10 and 3/5 is multiplied by 2 which makes 6/10.

Adding 5/10 and 6/10 is 11/10 or 1 1/10

13+6+9=28

28+1 1/10 = 29 1/10

and finally because we did surface area it is 29 1/10 CM^2

__________________________________________________________

To Find Volume:

The Equation used to find volume is l*w*h

The Length is 6 1/2

Height is 9 1/5

width is 3

First, lets again convert the fractions

5/10 and 6/10

6 5/10 times 9 6/10 is 62.4

62.4 times 3 is 187.2

The .2 and be put into 2/10 or 1/5  so the FINAL answer is 187 1/5

Another way to check this is

6*9*3=162

1/5*1/2
