The price elasticity of demand for the parakeet chow is 1.33.

Price elasticity of demand is the change in product quantity demanded to change in price.

From the question:

[tex]\%\ Change\ in \ quantity=\frac{30000-40000}{30000}= -33.3\%\\\\\%\ Change\ in \ price=\frac{20-16}{16}= 25\%\\\\PED=|\frac{\%\ Change\ in \ quantity}{\%\ Change\ in \ price} |=|\frac{-33.3\%}{25\%}|=1.33[/tex]

Answer:

how to understand the problem is picture the shape as a house and try to figure out what to do next

Step-by-step explanation:

Using the percentage concept, it is found that 25% of 6th graders are involved in the yearbook club.

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

[tex]P = \frac{a}{b} \times 100\%[/tex]

In this problem, 10 out of 10 + 24 + 6 = 40 6th graders are involved in the yearbook club, hence the corresponding percentage is given by:

[tex]P = \frac{10}{40} \times 100\% = 25\%[/tex]

Answer:

x( x - 5)( x + 2)

Step-by-step explanation:

The polynomial is x^3 - 3x^2 -10x. Since each term has at least one x, we can factor out an x.

This gives us x( x^2 - 3x - 10).

Now, we may factor the second degree polynomial.

_ × _ = -10? (or a × c, where ax^2 + bx + c?)

_ + _ = -3? (or b?)

Well, -5 times 2 equals 10, and -5 plus 2 equals -3.

We use these values to factor further.

So, our final answer becomes x( x - 5 )( x + 2 ).

You can check this by simply multiplying and distributing the terms!

Answer:

the container will hold 3m cudic meters

Answer:  161 m^2

Step-by-step explanation:

The surface area composes of 4 triangles and 1 square.

The side length of the square is 7 m, so the area is 49 m^2 because the area of a square is the side length^2.

Each of the triangles has a base of length 7 m and a height of 8 m, so the area of each triangle is 7m*8m/2 = 28 m^2 because the area of a triangle is the base*height/2.

Since there are 4 triangles, the total surface area of the 4 triangles is 28 m^2 * 4 = 112 m^2.

Adding that to the area of the square, we get 49 m^2 + 112 m^2 = 161 m^2

Answer:

The 90% confidence interval is  [tex] 0.0097 <  p_1 -p_2 < 0.0773 [/tex]

Step-by-step explanation:

From the question we are told that

   The first  sample size is [tex]n_1 =  620[/tex]

    The number of chips that failed is  k = 125

   The second sample size is [tex]n_2  =  820[/tex]

    The number of chips that fail is  [tex]u  = 130[/tex]

Generally the confidence level is  90% , hence the level of significance is  

    [tex]\alpha =  (100 - 90)\% [/tex]

=>  [tex]\alpha = 0.10 [/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.645[/tex]

Generally the first sample proportion is  

       [tex]\r p _1 =  \frac{125}{620}[/tex]

=>     [tex]\r p _1 = 0.202[/tex]

Generally the second  sample proportion is  

       [tex]\r p _1 =  \frac{130}{820}[/tex]

=>     [tex]\r p _1 = 0.1585[/tex]

Generally the standard error is mathematically represented as

[tex]SE =  \sqrt{\frac{\r p_1 (1 - \r  p_1)}{n_1} +\frac{\r p_2 (1 - \r  p_2)}{n_2}  }[/tex]    

=> [tex]SE =  \sqrt{\frac{0.202(1 - 0.202)}{620} +\frac{0.1585 (1 - 0.1585)}{820}  }[/tex]  

=>  [tex]SE = 0.0206[/tex]  

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } * SE[/tex]

=>     [tex]E = 1.645 * 0.0206[/tex]

=>    [tex]E =0.0338[/tex]

Generally 95% confidence interval is mathematically represented as  

      [tex](\r p_1 -\r p_2) -E <  p_1 - p_2 <  (\r p_1 -\r p_2) +E [/tex]

=>    [tex](0.202 -0.1585) -0.0338 <  p_1 - p_2 < (0.202 -0.1585) +0.0338 [/tex]

=>    [tex] 0.0097 <  p_1 - p_2 < 0.0773 [/tex]

There is 12 inches in total, given that one piece is 5 inches longer, the other part of the 5 inches would be 7 inches which is the longer side.

5 inches would be the shorter side.

Answer:

2x - 3y = 6

[tex]x = 3 + \frac{3y}{2}[/tex]

[tex]y = 2 + \frac{2x}{3}[/tex]

4y - x = 12

[tex]x = 12 + 4y\\y = 3 + \frac{x}{4}[/tex]

Step-by-step explanation:

Divide both sides of the equation to "solve for x and y."

Answer:

-1 and 3

Step-by-step explanation:

The roots of the quadratic function can be determined by [tex]f(x')=0[/tex] where x' is the roots of the quadratic function. In that graph, x = -1 and x = 3 makes the value of f(-1) = 0 and f(3) = 0. So, x = -1 and x = 3 are the roots of the f(x).

Step-by-step explanation:

1. A+B=Just add the J hat with J hat and add the I hat with the I hat.

[tex](3i + ( - 1)i + ( - 2) + ( - 4)j = 2i - 6j[/tex]

A-B=

[tex]3 - ( - 1)i + ( - 2) - ( - 4)j = 4i + 4j[/tex]

2. Take the magnitude of A+B

[tex]2 {}^{2} + ( - 6) {}^{2} = {r}^{2} [/tex]

[tex]40 = {r}^{2} [/tex]

[tex]r = \sqrt{40} [/tex]

So the magnitude is root of 40.

So the magnitude of A+B is

The magnitude of A-B

[tex] {4}^{2} + {4}^{2} = 4 \sqrt{2} [/tex]

So the magnitude is

[tex]4 \sqrt{2} [/tex]

c. To find direction, we need to find the angle.

Use this rule,

[tex] \tan(x) = \frac{bj}{bi} [/tex]

For A+B, we get

[tex] \tan(x )= \frac{ - 6}{2} [/tex]

[tex] \tan(x) = - 3[/tex]

Since this is a southeast, the degree is 288.43.

The direction is southeast, 288.43 degrees

For A-B, we get

[tex] \tan(x) = \frac{4}{4} [/tex]

[tex] \tan(x) = 1[/tex]

Since this is northeast, the degree is 45 degrees.

The direction is northeast, 45 degrees.

Answer:

x=12 pls give brainliest

Step-by-step explanation:

Answer: x = 12, Angle 1 = 38°

Step-by-step explanation: Complimentary angles add up to 90°.

Add the two angles and set them equal to 90°:

(3x + 2) + (4x + 4) = 90

Add like terms:

7x + 6 = 90

Subtract 6 from both sides:

7x = 84

Divide both sides by 7:

x = 12

Now, to get Angle 1, plug x in:

Angle 1 = 3(12) + 2

Angle 1 = 38°

Answer:

y = 2x + 4

Step-by-step explanation:

the equation of a line in point- slope form is

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

here m = 2 and passes through point (0, 4 ) ⇒ c = 4

y = 2x + 4 ← equation of line

Answer:

y = 2x + 4

Step-by-step explanation:

General form of linear equation:  y = mx + c

where m is the gradient and c is the y-intercept

Given gradient = 2  

⇒  m = 2  

⇒  y = 2x + c

y-intercept is when x = 0

Given (0, 4), so y = 4 when x = 0

⇒ c = 4

⇒ y = 2x + 4

Answer:

  x = 6

Step-by-step explanation:

Using the relationships between the entries in the table, you can find x two different ways.

The numbers down the Total column add to give the one at the bottom:

  0.1 + 0.09x = 0.64

  0.09x = 0.54 . . . . . . . subtract 0.1

  x = 6 . . . . . . . . . . . . divide by 0.9

__

The product of the numbers in the first two columns is the number in the third. On the bottom row, this means ...

  (2 +x)(0.08) = 0.64

  2 +x = 8 . . . . . . . . . . . divide by 0.08

  x = 6 . . . . . . . . . . . subtract 2
