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=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:

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 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]

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

Divide the number of defective by the total number of batteries then multiply by 100 to get the percent.

18/150 = 0.12

0.12 x 100 = 12%

Answer: 12%

Answer: Y= 2/3x + 9

Explanation: The equation is in slope-intercept form, y=mx+b. Since it is parallel to the equation, it has the same slope (2/3x) and since b is the x intercept, b is 9.

The equation in slope-intercept form for the line that is parallel to y=(2/3)x-10 and x-intercept at 9 is y =

What is a Linear Equation of a line?

A linear equation is an algebraic equation of the form y=m x + b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept

Parallel lines have the same slope.

Given data ,

The x-intercept is obtained when we set the value y = 0

As the x-intercept is 9 , therefore the point representing the x-intercept will be: ( 9 , 0 )

Now , the equation of line is given by y = m x + c

And , y = ( 2 / 3 ) x - 10

Since the lines are parallel , they will have same slope

So , the equation in slope intercept for the line will be

y = ( 2 / 3 ) x + 9

Hence the equation of line will be y = ( 2 / 3 ) x + 9

Answer:

180 in²

base b = 2 ft = 2*12 in = 24 in

height h = 15 in

Area = bh/2 = 24 * 15/2 = 180 in²

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

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.
