Answer:

7.855 inches

Step-by-step explanation:

The formula to find the length of an arc is :

Arc Length = $\frac{\theta}{360}$ × 2 π r

Here,

Θ ⇒ size of the angle ⇒ 30°

r ⇒ radius ⇒ 15 inches

<u>Let us solve it now.</u>

Arc length = $\frac{\theta}{360}$ × 2 π r

Arc length = $\frac{30}{360}*2*\pi*15$

Arc length = $\frac{30*2*\pi*15}{360}$

Arc length = $\frac{2827.8}{360}$

Arc length = 7.855 inches

Let me know if you have any other questions. :)

How to solve this problem

lozanna [386]

Answer:

Step-by-step explanation:

We are given the equation 3 - 4x - 2 = 2x - 11;

$3 - 4x - 2 = 2x - 11,\\3 - 2 = 6x - 11,\\1 = 6x - 11,\\12 = 6x,\\\\x = 2\\Conclusion, x = 2$

1&3\\
p&36
\end{array}\implies \cfrac{1}{p}=\cfrac{3}{36}\implies \cfrac{1\cdot 36}{3}=p$

A professora Luísa observou que o numero de meninas de turma dividido pelo numero de meninos dessa turma e 0,48. Qual e o menor

saw5 [17]

Respuesta:

37 estudiantes

Explicación paso a paso:

El número de niños dividido por el número de niñas = 0,48

Dejar :

x = número de niños; y = número de niñas

Tenemos ;

x / y = 0,48

Conversión a decimal;

0.48 es equivalente a 48/100

Reduciendo a la forma más simple:

48/100 = 12/25

Comparando:

x / y = 12/25

x = 12; y = 25

El menor número posible de estudiantes:

x + y = 12 + 25 = 37 estudiantes

How do you Calculate the mean,median and mode in grouped data.

Dmitrij [34]

Answer:

The mean:

data: 3,6,9,10

You first add all of the numbers together.

3+6+9+10= 28

There 4 numbers in the data set, so you divide 4 by the sum of all of the numbers.

28/4= 7

So the mean is 7.

The median:

data: 3,6,9,10

first put all of the numbers in numerical order.

3,6,9,10

Then you find the middle number in the data set.

3,6,(the middle number here),9,10

to find the middle number, do the mean of 6 and 9

The mean of 6 and 9 is 7.5

So, 7.5 is the median

another example: 3,4,7,9,13

The middle number is 7

so 7 is the median

The mode:

data: 3,6,9,10

The mode is the number that is repeated the most

in this data, there is no mode.

but in this data: 4,4,6,9,11

4 is the mode because it was repeated the most
