Follow the directions to convert the analog sound wave into a digital signal. The lines on the grid intersect at various points (x, y). For each whole-number value of x, find the intersection point that is closest to the wave. Draw a small circle on that point, and record its y-value. The circles for the x-values 0 through 3 are already done for you. Draw circles for the x-values 4 through 18. In a textbox, write down all 19 y-values obtained by sampling the wave.

Answer:

y=2x-8

Step-by-step explanation:

y=Mx+k

Plug in(3,-2)(6,4)

3m+k=-2

6m+k=4

First function multiply by 2,we got:

6m+2k=-4

6m+k=4

k=-8

Y=Mx-8

Plug in any points that is in the question, I use(6,4)

4=6m-8

m=2

Y=2x-8

Answer:

y = 2x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, - 2) and (x₂, y₂ ) = (6, 4)

m = [tex]\frac{4+2}{6-3}[/tex] = [tex]\frac{6}{3}[/tex] = 2, then

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (6, 4 ), then

4 = 12 + c ⇒ c = 4 - 12 = - 8

y = 2x - 8 ← equation of line

Step-by-step explanation:

y = 3*x  + 4

y = 3*x -   7

Each one of the above equations is the equation for a straight line.

The solution for such a system is the point P ( x₀ , y₀ ) which coordinates belong to both straight lines. According to this, there is only one solution for that system ( only one point of intersection). The intersection of a pair of straight lines either can occur or not depending on the slope of the lines, if they have the same slope they are parallel, then they did not touch each other ever. How can m,  be identified in the straight line equation??,   just by looking at the coefficient of x.  

The two equations have slope 3 they are parallel then there is not a solution ( there is not a common point to both equations)

Step-by-step explanation:

X 0 1 2 3 4

P(X) 0.1 0.2 0.4 0.2 0,1

a) Find the probability of 1 tire with low air pressure P (1) :

From probability distribution table Given :

P(1) = 0.2

b) Find the probability of more than 2 tires having low air pressure P (more than 2) =

P(x > 2) = p(3) + p(4)

P(x > 2) = 0.2 + 0.1 = 0.3

c) P (all 4 tires)

From the table :

P(x = 4) = 0.1

d) Compute the expected number of tires with low air pressure.

E(X) = Σx * p(x)

E(x) = (0*0.1) + (1*0.2) + (2*0.4) + (3*0.2) + (4*0.1) = 2

Answer:

Angle measure KRQ is 146 degrees

Step-by-step explanation:

Here, we want to find the measure of the indicated angle

From what we have in the question;

angle measure KRQ is corresponding to angle measure KNM

Mathematically, when two angles are corresponding to each other, their values are equal

What this means is that the value of the measure of KRQ is 146 degrees too

9514 1404 393

Answer:

  x = 25; ∠3 = ∠6 = 60°

Step-by-step explanation:

Angles 3 and 6 are alternate interior angles, so are congruent.

  2x +10 = 3x -15

  25 = x . . . . . . . . . . . add 15-2x

  2x +10 = 2(25) +10 = 60

The measures of angles 3 and 6 are 60°.

The number 2 or 6 would be rolled 200 times.

Important information:

Number cube has six numbers 1, 2, 3, 4, 5, 6. So, the probability of getting either 2 or a 6 is:

[tex]P(2\cup 6)=\dfrac{2}{6}[/tex]

[tex]P(2\cup 6)=\dfrac{1}{3}[/tex]

The expected value of getting a 2 or a 6 would be rolled is:

[tex]E(2\cup 6)=600\times P[/tex]

[tex]E(2\cup 6)=600\times \dfrac{1}{3}[/tex]

[tex]E(2\cup 6)=200[/tex]

Therefore, the number 2 or 6 would be rolled 200 times.

Answer:

672 square inches

Step-by-step explanation:

i took the test and got this question right

The area of Mason's birdhouse is 664 square inches.

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

For the area of Mason's birdhouse,

We need to calculate the surface area of all the sides and add them up.

Now,

The birdhouse has six sides.

= a top, bottom, front, back, left, and right side.

The top and bottom of the birdhouse are both rectangles with dimensions 10 inches by 8 inches.

So,

The area of each rectangle.

=  10 in × 8 in

= 80 square inches

So,

The total area of the top and bottom of the birdhouse.

= 2 × 80 square inches

= 160 square inches

Now,

The front and back of the birdhouse are both rectangles with dimensions 10 inches by 14 inches.

The area of each rectangle.

=  10 in × 14 in

= 140 square inches

The total area of the front and back of the birdhouse.

= 2 × 140 square inches

= 280 square inches

Now,

The left and right sides of the birdhouse are both rectangles with dimensions 8 inches by 14 inches.

The area of each rectangle.

= 8 in × 14 in

= 112 square inches

The total area of the left and right sides of the birdhouse.

= 2 × 112 square inches

= 224 square inches

Now,

The total surface area of Mason's birdhouse.

= 160  + 280 + 224

= 664 square inches.

Thus,

The area of Mason's birdhouse is 664 square inches.

Answer:

x = 25/2

Step-by-step explanation:

We may apply the property of triangles that says the three angles must add up to 180 degrees.  Therefore:

x + 4 + x + 61 + 90 = 180

2x + 65 = 90, or

2x = 25, and so x = 25/2
