Answer:0.75

Step-by-step explanation:

Answer: 3/4

Step-by-step explanation:

9 inches to feet is 0.75

0.75 as a fraction is 3/4

Answer:

for class A

mean ={3+4+8(5)+6+7)/12}=5hours

mean absolute deviation (MAD) for A

=[|5-3|+|5-4|+8|5-5|+|5-6|+|5-7|]/12=6/12=1/2

for class B

mean =4 hours given

mean absolute deviation (MAD) for B

=[|4-7|+|4-8|+8|4-9|+|4-10|+|4-11|]/12=60/12=5

Answer:

Step-by-step explanation:

we are given some data 3,4,5,5,5,5,5,5,5,5,6,7

we want to figure out the MAD (Mean absolute deviation) of the given database

remember that,

[tex] \rm\displaystyle \: MAD = \frac{1}{n} \sum_{i = 1} ^{n} |x_{i} - m(x)| [/tex]

where m(X) represents the mean of the given database and [tex]|x_{i}-m(X)|[/tex] tells us to subtract every data with the got mean and n represents the number of data

let figure out m(X)

[tex] \rm\displaystyle \: m(x) = \frac{3 + 4 + 5(8) + 6 + 7 }{12} [/tex]

simplify multiplication:

[tex] \rm\displaystyle \: m(x) = \frac{3 + 4 + 40 + 6 + 7 }{12} [/tex]

simplify addition:

[tex] \rm\displaystyle \: m(x) = \frac{60}{12} [/tex]

simplify substraction:

[tex] \rm\displaystyle \: m(x) = 5[/tex]

let's figure out [tex]\sum[/tex] and [tex]|x_i-m(X)|[/tex]

[tex] \displaystyle\begin{array} {|c |c| } \hline |x_{i} - m(x) | & \displaystyle\sum_{i = 1} ^{n} |x_{i} - m(x) | \\ \hline |3 - 5 | & 2 \\ \hline | 4 - 5 | &1 \\ \hline |5(8) - 5(8)| &0 \\ \hline |6 - 5|&1 \\ \hline |7 - 5| &2 \\ \hline \\ \text{total} & 5 \\ \hline\end{array}[/tex]

last part let's figure out MAD

[tex] \displaystyle \: MAD = \frac{5}{12} [/tex]

simplify division:

[tex] \displaystyle \: MAD = 0.42[/tex]

likewise class-2

given database 7,8,9,9,9,9,9,9,9,9,10,11

figure out m(X)

[tex] \rm\displaystyle \: m(x )= \frac{7 + 8 + 9(8) + 10 + 11}{12} [/tex]

simplify multiplication:

[tex] \rm\displaystyle \: m(x )= \frac{7 + 8 + 72 + 10 + 11}{12} [/tex]

simplify addition:

[tex] \rm\displaystyle \: m(x )= \frac{108}{12} [/tex]

simplify division:

[tex] \rm\displaystyle \: m(x )= 9[/tex]

likewise

figure out [tex]\sum[/tex] and [tex]|x_i-m(X)|[/tex]

[tex] \displaystyle\begin{array} {|c |c| } \hline |x_{i} - m(x) | & \displaystyle\sum_{i = 1} ^{n} |x_{i} - m(x) | \\ \hline |7 - 9 | & 2 \\ \hline | 8- 9 | &1 \\ \hline |9(8) - 9(8)| &0 \\ \hline |10 - 9|&1 \\ \hline |11- 9| &2 \\ \hline \\ \text{total} & 5 \\ \hline\end{array}[/tex]

figure out MAD

[tex] \displaystyle \: MAD = \frac{5}{12} [/tex]

simplify division:

[tex] \displaystyle \: MAD = 0.42[/tex]

Answer:

A11 = 230.66015625

Step-by-step explanation:

hi!

the first thing that you have to do when solving for the 11th term in a geometric sequence is to find the common ratio!

I did this by dividing 6/4 = 3/2 (I did multiply this by 6 to test if it was correct, and it was)

the next thing you can do is use this formula:

An = A1*r^(n-1)

An = the nth term of the sequence

A1 = the first term in the sequence

r = common ratio

n = the number of term that you are solving for

A11 = 4*(3/2)^(11-1)

A11 = 4*(3/2)^10

A11 = 230.66015625

Answer:

The answer is x = -11

Answer:

8x+207=6x+185

8x-6x=185-207

2x=-22

divide by 2

x=-11

Answer:

Perimeter of rectangle = 4x + 80

Area = x² + 40x + 384

Step-by-step explanation:

Perimeter of rectangle = 2*(length + width)

                                      = 2* (x + 24 + x + 16)

                                      = 2*( x +x + 24 + 16)    {Combine like terms}

                                      = 2* (2x + 40)

Use Distributive property : a*(b +c) = a *b + a*c

                                     = 2*2x + 2*40

                                     = 4x + 80

Area of rectangle = length * width

                             = (x + 24) (x + 16) {use FOIL method}

                            = x*x + x*16 + 24*x + 24*16

                             = x² + 16x + 24x + 384  {Combine like terms}

                             = x² + 40x + 384

Pregunta completa:

Una caja contiene lápices azules y rojos. ¿Cómo se interpreta que la relación entre

los lápices azul y rojo en la caja es 3: 1?

A Hay tres lápices rojos y un lápiz azul.

B Hay tres lápices azules y un lápiz rojo.

C Hay tres veces más lápices rojos que azules.

D Hay tres veces más lápices azules que rojos.

Responder:

B Hay tres lápices azules y un lápiz rojo.

Explicación paso a paso:

Si se le da eso; La relación entre los lápices azul y rojo es de 3: 1

El primer número en la expresión de razón representa el color del lápiz indicado primero en la expresión

Por lo tanto ;

Lápiz de color azul = 3

Lápiz de color rojo = 1

Por lo tanto, hay tres lápices azules y un lápiz rojo.

Answer:

5 feet high

Step-by-step explanation:

A= LxW

Yx4= 20

  /4    /4

Y= 5ft

It is 5ft high

Answer:

The length is 9 feet and the width is 4 feet.

Step-by-step explanation:

Let the dimensions be L (the length)  and L - 5 (the width).

From the given information the area is:

A = L(L - 5)

When L becomes L + 3 and width becomes (L - 5) -1  = L - 6 we have:

A = (L + 3)(L - 6) so

L(L - 5) = (L + 3)(L - 6)

L^2 - 5L = L^2 - 3L - 18

-2L  = -18

L = 9

so the width = 9 - 5 = 4.

Answer:

+4√5

Step-by-step explanation:

Note that this is a right triangle.  Therefore, the lengths of the three sides are related through the Pythagorean Theorem:  a^2 + b^2 = c^2, where c is the length of the hypotenuse.  

Thus, x^2 + 19^2 = 21^2, or, after solving this for x^2,

x^2 = 441 - 361 = 80

x is therefore +√80, or +4√5.

Answer:

50

Step-by-step explanation:

All angles around a circle is 360°

/_ 2 = 130°

/_ 1 = 130° (Vertically opposite angles)

= 130° + 130° = 260°

all angles = 360°

= 360° - 260° = 100°

= 100° ÷ 2

= 50°

= /_ 3 and /_ 4 = 50°

Verification = 130° + 130° + 50° + 50° = 360°

Answer:

Decrease

Step-by-step explanation:

50 is bigger than 20, so it's decreasing and the units are the same.

Answer:

1 batch

Step-by-step explanation:

Farah needs 4 and 4/5 pounds of tomatoes & and additional 5 and 3/5 pounds of tomatoes to make soup.

4.8 + 5.6 = 10.5 pounds per soup

10.5*2 = 21 > 20 pounds

Farah would need one more pound of tomatoes in order to make 2 batches of soup. Therefore she can only make 1 batch.

4*2/2= 4

So 4units^2 is the area

Answer:

4 unit²

Step-by-step explanation:

Here,

base = 2

height = 4

Area of the triangle = 1/2 x base x height

= 1/2 x 2 x 4

= 4 unit²
