The complete table of values of the linear equation is

x | y

0 | 1

1 | 4

2 | 7

3 | 10

-1 | -2

The ordered pairs are (x, y) = (0, 1), (1, 4), (2, 7), (3, 10) and (-1, -2)

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The linear equation of the function is given as

y = 3x + 1

On the incomplete table of values, we have the following x values

x = 0, 1, 2, 3, -1

Next, we substitute x = 0, 1, 2, 3, -1 in the equation y = 3x + 1

So, we have:

y = 3 x 0 + 1 = 1

y = 3 x 1 + 1 = 4

y = 3 x 2 + 1 = 7

y = 3 x 3 + 1 = 10

y = 3 x -1 + 1 = -2

So, the complete table of values of the linear equation is

x | y

0 | 1

1 | 4

2 | 7

3 | 10

-1 | -2

When represented as ordered pairs, we have

(x, y) = (0, 1), (1, 4), (2, 7), (3, 10) and (-1, -2)

Triangles are known to be three-sided polygons having three vertices. It is one of the basic geometric forms. The name for a triangle with vertices A, B, and C is triangle ABC.

We must think about the triangle inequality theorem, which states that the total of the lengths of any two sides of a triangle must be greater than the length of the remaining side, to figure out which measurements can produce more than one triangle.

Answer:

  (b) 27°

  (c) 34°

  ( ) 27°

Step-by-step explanation:

Angle relations involving lines, parallel lines, and triangles come into play here.

The interior angles at W and Y will be the supplement of the exterior angles at those points. The sum of interior angles is 180°.

  (180° -6x) +90° +(180° -4x) = 180°

  270° = 10x . . . . . . . . . add 10x and simplify

  27° = x

The vertical angles at S are congruent. This tells us ...

  3x +∠PSQ = 4x

  ∠PSQ = x

The sum of angles in triangle PSQ is 180°, so we have ...

  x +x +(180° -68°) = 180°

  2x = 68° . . . . . . . . add 60°-180°

  x = 34° . . . . . . . . . divide by 2

Angles BAD and EDF are corresponding angles, hence congruent. The sum of angles in triangle BAD is 180°.

  2x +2x +72° = 180°

  4x = 108° . . . . . . subtract 72°

  x = 27° . . . . . . . . divide by 4

Answer:

We have two consecutive even integers:

a and b.

We know that we can write a even integer as:

a = 2*n

where n is an integer.

Then the consecutive integer to a, b, will be:

b = 2*n + 2.

Then the sum of a and b is:

a + b = 2n + 2n + 2 = 4*n + 2 = 2*(2n + 1) = k.

The next two consecutive integers greater than b will be:

c = 2n + 4

d = 2n + 6

then:

c + d = (2n + 4) + (2n + 6) = 4n + 10 = k + 4.

Question:

The scatter plot shows the maximum noise level when different numbers of people are in a stadium. The linear model is given by the equation y=1.5x + 22.7 where y represents maximum noise level and x represents the number of people, in thousands, in the stadium.​​​​​​

A sports announcer states that there are 65,000 fans in the stadium. Estimate the maximum noise level. Is this estimate reasonable? Explain your reasoning.

Answer:

\(y = 97522.7\)

Step-by-step explanation:

Given

\(y = 1.5x + 22.7\)

\(x = 65000\)

Required

Find y

Substitute 65000 for x in the given equation

\(y = 1.5 * 65000 + 22.7\)

\(y = 97500 + 22.7\)

\(y = 97522.7\)

It is reasonable because as the population increases, the noise level also increases

the answer is b

Factory A sent 14 loads of rice to Store 1

Factory A sent no loads of rice to Store 2

Factory B sent 6 loads of rice to Store 1

Factory B sent 16 loads of rice to Store 2

Let

    A1 = Loads sent from Factory A to Store 1

    A2 = Loads sent from Factory A to Store 2

    B1 = Loads sent from Factory B to Store 1

    B2 = Loads sent from Factory B to Store 2

Then, the equations describing the scenario are;

    \(A1+A2=14\)

    \(B1+B2=22\)

    \(A1+B1=20\)

    \(A2+B2=16\)

    \(200A1+350A2+300B1+250B2=8600\)

The simultaneous equations can be expressed in matrix form thus:

\(\left[\begin{array}{ccccc}{A1}&{A2}&{B1}&{B2}&{}\\1&1&0&0&14\\0&0&1&1&22\\1&0&1&0&20\\0&1&0&1&16\\200&350&300&250&8600\end{array}\right]\)

Reducing the matrix:

Step 1:

\(R_3 \leftarrow R_3 - R_1\\R_5 \leftarrow R_5 - 200R_1\)

\(\left[\begin{array}{ccccc}{A1}&{A2}&{B1}&{B2}&{}\\1&1&0&0&14\\0&0&1&1&22\\0&-1&1&0&6\\0&1&0&1&16\\0&150&300&250&5800\end{array}\right]\)

Step 2:

Switch \(R_4\) and \(R_2\)

\(\left[\begin{array}{ccccc}{A1}&{A2}&{B1}&{B2}&{}\\1&1&0&0&14\\0&1&0&1&16\\0&-1&1&0&6\\0&0&1&1&22\\0&150&300&250&5800\end{array}\right]\)

Step 3:

\(R_3\leftarrow R_3+R_2\\R_5 \leftarrow R_5-150R_2\)

\(\left[\begin{array}{ccccc}{A1}&{A2}&{B1}&{B2}&{}\\1&1&0&0&14\\0&1&0&1&16\\0&0&1&1&22\\0&0&1&1&22\\0&0&300&100&3400\end{array}\right]\)

Step 4:

\(R_4\leftarrow R_4+R_3\\R_5 \leftarrow R_5-300R_3\)

\(\left[\begin{array}{ccccc}{A1}&{A2}&{B1}&{B2}&{}\\1&1&0&0&14\\0&1&0&1&16\\0&0&1&1&22\\0&0&0&0&0\\0&0&0&-200&-3200\end{array}\right]\)

Step 5:

Switch \(R_4\) and \(R_5\)

\(R_4\leftarrow R_4 \times \frac{1}{-200}\\R_1 \leftarrow R_1-R_2\)

\(\left[\begin{array}{ccccc}{A1}&{A2}&{B1}&{B2}&{}\\1&0&0&-1&-2\\0&1&0&1&16\\0&0&1&1&22\\0&0&0&1&16\\0&0&0&0&0\end{array}\right]\)

Step 6:

\(R_1 \leftarrow R_1 + R_4\\R_2\leftarrow R_2 - R_4\\R_3 \leftarrow R_3-R_4\)

So,

\(A1=14\\A2=0\\B1=6\\B2=16\)

From the above calculations, we see that

Factory A sent 14 loads of rice to Store 1

Factory A sent no loads of rice to Store 2

Factory B sent 6 loads of rice to Store 1

Answer:

The expected value of this policy to the insurance company is $206.97

Step-by-step explanation:

Probability that Person doesn't die = 0.999563. Profit = Revenue - Cost; Profit = $290 - 0 = $290

Probability that Person dies = 1 - 0.999563 = 0.000437. Profit = Revenue - Cost; Profit = $290 - $190,000 = -$189,710

Expected Value E(X) = ∑xp(x)

E(X) = $290*(0.999563) + (-$189,710* 0.000437)

E(X) = $289.87327 - $82.90327

E(X) = $206.97

Thus, the expected value of this policy to the insurance company is $206.97

Answer:

∠ BDC = 29°

Step-by-step explanation:

the sides of a rhombus are congruent, so CD = ED and Δ EDC is therefore isosceles with base angles congruent , then

∠ BCD = ∠ BED = 61°

• the diagonals are perpendicular bisectors of each other , then

∠ CBD = 90°

the sum of the 3 angles in Δ BCD = 180°

∠ BDC + ∠ CBD + ∠ BCD = 180°

∠ BDC + 90° + 61° = 180°

∠ BDC + 151° = 180° ( subtract 151° from both sides )

∠ BDC = 29°

Answer:

2500

Step-by-step explanation:

Dimensions of first level

Length = Breadth = 75 ft (since it is a square)

It is assumed that a person will occupy \(2.25\ \text{ft}^2\)

Area of first level

\(75\times 75=5625\ \text{ft}^2\)

When the area of the level is divided by the area of one person then we will get the number of people that can occupy the room or the number of tickets that can be sold.

\(\dfrac{5625}{2.25}=2500\)

The number of tickets that can be sold for the first level is 2500.

The answer is B because different X values cannot have the same y values. For example in A the x values, -2 and 0, have the same y value 4. That's not possible.

Although C also has a similar problem ALL of the X values have the same y value meaning that the function is an undefined function which is still a type of function. Its basically a function where all the y values are the same.
