Answer:

B, Supplementary

Step-by-step explanation:

Two angles are supplementary when both of them add up to ONLY 180.

Answer:

the answer is supplementary

Answer:

So we are told they are congruent: Hence

Answer and Step-by-step explanation:

Due to the transversal line from point D to point B, angle ABC and angle CDE are congruent. To find x, we set them equal to each other.

61 = 2x

Divide each side by 2.

30.5 = x

Answer:

104 is the answer to the question

Step-by-step explanation:

10(11)-6=110-6=104

Answer:

3.5325

Step-by-step explanation:

V = 3.14*(.75^2)(2)

You divide the diameter by 2 to get the radius which is 1.5/2 =.75

r=.75

h=2

and you use the equation for volume of cylinder which is V = pi x radius squared x height

Answer:

1.17126x 10*2

Step-by-step explanation:

Answer:

x must be 13

Step-by-step explanation:

Represent the nine scores by a, b, c, d, e, f, g, h, i.

Write the following equation to indicate that the average of these nine scores is 8:

a+b+c+d+e+f+g+h+i

----------------------------- = 8, or a+b+c+d+e+f+g+h+i = 72 if we multiply both

               9                      sides of this equation by 9.

Next, we add scores x and x+ 1 to

a+b+c+d+e+f+g+h+i  +  x + x + 1

and divide the result by 11, as there are now 11 scores instead of just 9:

a+b+c+d+e+f+g+h+i  +  x + x + 1

----------------------------------------------

                        11

Earlier, we saw that a+b+c+d+e+f+g+h+i = 72.  We can now replace

a+b+c+d+e+f+g+h+i in the above fraction by 72:

 72 + 2x + 1

------------------- = 9 (as the new average is 9)

         11

Multiplying both sides of this equation by 11 results in:

73 + 2x = 99, or  2x = 26.

Then x must be 13, and x + 1 must be 14.

Answer:

[tex]x=11[/tex]

Step-by-step explanation:

The sum of all the angles in a triangle is always 180 degrees.

Hence,

[tex](7x-17)+42+78=180[/tex]

Remove the brackets:

[tex]7x-17+42+78=180[/tex]

Add/Subtract the numbers:

[tex]7x+103=180[/tex]

Subtract 103 from both sides:

[tex]7x+103-103=180-103[/tex]

[tex]7x=77[/tex]

Divide both sides by 7:

[tex]\frac{7x}{7}=\frac{77}{7}[/tex]

[tex]x=11[/tex]

Answer:

X = 11

Step-by-step explanation:

This triangle will add up to 180 degrees

Our angles we have right now our 42 and 78 I add those up so I know how much the missing angle will have to equal to add up with the others to equal 180 so 42 + 78 = 120

So our other angle will have yo equal 60 so we have to find out what multiplied by 7 subtracted by 17 equals 60 well 7 x 11 = 77 and 77 - 17 = 60 so x = 11

Given:

The degree of the polynomial = 3

Leading coefficient = 1

Zeros of the polynomial are 5 and 4i.

To find:

The expanded form of the polynomial.

Solution:

According to the complex conjugate root theorem, if a+ib is a zero of a polynomial, then a-ib is also a zero of that polynomial.

Here, zeros of the polynomial are 5 and 4i. It means the third zero of the polynomial is -4i. So, the factors of the polynomial are [tex](x-5),(x-4i),(x+4i)[/tex].

The required polynomial is the product of its all factor and a constant which is equal to the leading coefficient. Here, the constant is 1. So, the required polynomial is

[tex]P(x)=1(x-5)(x-4i)(x+4i)[/tex]

[tex]P(x)=(x-5)(x^2-(4i)^2)[/tex]

[tex]P(x)=(x-5)(x^2+16)[/tex]             [tex][\because i^2=-1][/tex]

[tex]P(x)=(x-5)(x^2+16)[/tex]

On further simplification, we get

[tex]P(x)=x^3+16x-5x^2-80[/tex]

[tex]P(x)=x^3-5x^2+16x-80[/tex]

Therefore, the required polynomial P is [tex]P(x)=x^3-5x^2+16x-80[/tex].

Answer: [tex]\dfrac{14}{55}, \dfrac{13}{55}[/tex]

Step-by-step explanation:

Given

There are 8 red and 4 blue beads

Three beads were taken from the box

(i)No of ways of choosing three red beads out of 12 beads is [tex]^8C_3[/tex]

Total no of ways [tex]^{12}C_3[/tex]

Probability is

[tex]P=\dfrac{^8C_3}{^{12}C_3}=\dfrac{8\times 7\times 6}{12\times 11\times 10}=\dfrac{2\times 7}{11\times 5}\\P=\dfrac{14}{55}[/tex]

(ii)atleast two beads refers to minimum two beads

There can be two possibilities (2B,1 R), (3B, 0R)

[tex]\Rightarrow P=\dfrac{^4C_2\times ^8C_1}{^{12}C_3}+\dfrac{^4C_3}{^{12}C_3}\\\\\Rightarrow P=\dfrac{6\times 8}{220}+\dfrac{4}{220}=\dfrac{52}{220}\\\\\Rightarrow P=\dfrac{13}{55}[/tex]

Answer:

P = 2/3 = 0.67

Step-by-step explanation:

Assuming that X1 + X2 = 7

The total number of outcomes such that X1 + X2 = 7 are:

X1 = 3, X2 = 4

X1 = 4, X2 = 3

X1 = 1, X2 = 6

X1 = 6, X2 = 1

X1 = 2, X2 = 5

X1 = 5, X2 = 2

So there are 6 total outcomes such that X1 + X2 = 7

Now, the probability that X1 = 4 is equal to the quotient between the number of outcomes where X1 = 4 (only one outcome) and the total number of outcomes (6)

Then:

p = 1/6

And the probability that X2 = 4 is calculated in the same way, then the probability is:

q = 1/6

Now, the probability that X1 = 4 or X2 = 4 is the sum of both probabilities we've found above, then:

P = p + q = 1/6 + 1/6 = 2/6 = 2/3 = 0.67

Answer:

(3, - 1 )

Step-by-step explanation:

Given the 2 equations

3x + y = 8 → (1)

7x - 4y = 25 → (2)

Multiplying (1) by 4 and adding to (2) will eliminate the y- term

12x + 4y = 32 → (3)

Add (2) and (3)  term by term to eliminate y

19x + 0 = 57

19x = 57 ( divide both sides by 19 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (1)

3(3) + y = 8

9 + y = 8 ( subtract 9 from both sides )

y = - 1

solution is (3, - 1 )

Answer:  x = 9

Step-by-step explanation:

The sum of three interior angles of a triangle is 180°.

(9x - 3)  + (6x)  + 48° = 180°

9x - 3 + 6x + 48 = 180

15x + 45 = 180

15x = 135

x = 9
