Answer:

Answer: X is equal to -1

Step-by-step explanation:

1-2(2X+1)=1-(X-1)

1-4X-2=1-X+1

-1-4X=2-X

-4X+X=2+1

-3X=3

X=-1

Answer:

C) is the correct answer

Step-by-step explanation:

In order to find an average, you need to add x, y, and z and then divide them by 3 because there are 3 test scores, and x, y, and z represent the grades for each test. This is why C) x+y+z/3 is correct.

Answer:

a. mean = 1000

standard deviation = 4358.9

b. expected value of average damage bar Y = 1000

probability bar y exceeds 2000 = 0.011

Step-by-step explanation:

we have p1 = 95%, y1 = 0, p2 = 5%, y2 = 20000

Mean = (0.95 * 0) + (0.05 * 20000)

= 1000

var(y) = E(y²) - E(Y)²

= we solve for E(y)²

= 0²*0.95 + 20000²*0.05

= 0 + 20000000

then the variance of y = 20000000 - 1000²

=20000000-1000000

= $19000000

standard  deviation is the square root of variance

= √19000000

= 4358.9

2.

a. Expected value of average is also the mean = 1000

b. we are to find probability that barY exceeds 2000

[tex]z=\frac{2000-1000}{\sqrt{19000000/100} }[/tex]

= 1000/435.889

= 2.29

1-p(z≤2.29)

= 1 - 0.989

= 0.011

so the probability that barY exceeds 2000 is 0.011

Answer:

B

Step-by-step explanation:

diameter = hyp

hyp = (8^2 + 10^2)^1/2

[tex]= 2\sqrt{41}[/tex]

area of semicricle = pi r^2 /2

= 82 pi

area of triangle = 1/2 bh

= 1/2 x 8 x 10

= 40

area of shaded = area of semicricle + area of triangle

= 297.3

the answer is B

Answer:

daffodil = $13 Tulip = $7

Step-by-step explanation:

6t + 12d = 198

7t + 6d = 127

6t = 198 - 12d

t = 33 -2d

substitute

7(33-2d) + 6d = 127

231 -14d +6d = 127

- 8d = -104

d =13

6t + 12(13) = 198

6t +156 = 198

6t = 42

t = 7

Answer:

55°

Step-by-step explanation:

The angle is part of a 90° angle, so you do 90°-35° to get 55°.

Give branliest please. :)

Answer:

90 degrees - 35 degrees = x degrees, this will give you 55 degrees

Answer:

71 degrees, Acute angle

Step-by-step explanation:

From the question, the equation for the Angle is given to be 19x-5, given in degrees and they want to find the value of the angle when the variable X is equal to 4.

All we need to do is change X with 4 in this equation to get

(19x4)-5) Now we just need to do some basic arithmetic to find out the value.

(76-5)=71, So 71 degrees. Now let's classify all the types of angles

1-89 degrees is a acute angle

90 degrees Is a right angle

91-179 is a obtuse angle

180 is a Straight angle

181-359 is a reflex angle

360 is a full turn.

Notice how our 71 degree angle falls into the category of a acute angle (1-89)

So our final Answer is that the angle is 71 degrees and a acute angle.

Answer:

∠ P = 71° and is acute

Step-by-step explanation:

Acute angle is between 0° and 90°

Right angle = 90°

Obtuse angle is between 90° and 180°

Straight angle = 180°

Given

∠ P = 19x - 5 ← substitute x = 4

      = 19(4) - 5 = 76 - 5 = 71° ← acute angle

Answer:

Step-by-step explanation:

Length (L) = 8cm

Breadth (B) = 4cm

Height (H) = 3cm

........................................

Volume = L × B × H

Answer:  Where is question?

Step-by-step explanation:

Answer:

C. [tex]\ln z = 5.6157 + i\,\pi[/tex]

Step-by-step explanation:

Let [tex]z = a + i\,b[/tex], [tex]\forall\, a, b\in \mathbb{R}[/tex], the natural logarithm of a this number is:

[tex]\ln z = \ln \|z\|+i\, \theta[/tex] (1)

Where:

[tex]\|z\|[/tex] - Norm of the complex number, no units.

[tex]\theta[/tex] - Direction of the complex number, in radians.

The norm and direction of the complex number are both defined by:

[tex]\|z\| = \sqrt{a^{2}+b^{2}}[/tex] (2)

[tex]\theta = \tan^{-1}\left(\frac{b}{a} \right)[/tex] (3)

If we know that [tex]z = -274.7 +\,i \, 0[/tex], then the natural logarithm of this number is:

[tex]\|z\| = 274.7[/tex], [tex]\theta = \pi\,rad[/tex]

[tex]\ln z = \ln \|z\|+i\, \theta[/tex]

[tex]\ln z = 5.6157 + i\,\pi[/tex]

Hence, correct answer is C.

Answer: <LMJ and < KJM

Step-by-step explanation:

Answer:

Step-by-step explanation:

20 = 5y

4=y

x+3y = 2(x+y-1)

x+3y = 2x +2y -2

x+3(4) = 2x + 2(4) -2

x +12 = 2x +8 -2

12-8+2 = 2x -x

6 =x

The values of x and y that makes the polygon a parallelogram is 6 and 4 respectively.

A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal, and opposite angles equal.

Given is a polygon,

We know opposite sides of a parallelogram are equal,

Therefore,

5y = 20

y = 20/5

y = 4

And,

Putting y = 4, in x+3y = 2(x+y-1)

x+12 = 2(x+3)

x+12 = 2x+6

x = 12-6

x = 6

Hence, The values of x and y that makes the polygon a parallelogram is 6 and 4 respectively.
