What is the radius and diameter of the following circle? 11 cm

yanalaym [24]

Answer:

Diameter is 11cm, and the radius is 5.5

Step-by-step explanation:

To get the radius, just divide the size of the circle by 2

Diameter is the same size as the circle

Find the x- and y- intercepts of y = |x+1| -3 Someone help me please

zepelin [54]

Answer:

x-intercepts: (-4,0) and (-2,0) y-intercepts: (0,-2)

Step-by-step explanation:

x-intercept:

y = |x+1| - 3

0 = |x+1| - 3

3 = |x+1|

The numbers -4 and 2 are the x-intercepts because if you add -4 and 1, you get the absolute value of -3, which is 3. If you add 2 and 1, you get the absolute value of 3, which is 3.

y-intercept:

y = |x+1| - 3

y = |0+1| - 3

y = |1| - 3

y = 1 - 3

y = -2

1, 3, 6, 10, 15 is it arithmetic, geometric or neither

Gekata [30.6K]

The given sequence is neither arithmetic nor geometric.

Further explanation:

In order to check whether a sequence is geometric or arithmetic we have to find the common ratio and common difference respectively

Common difference is the deifference between cunsecutive terms of a sequence while common ratio is the ratio between two consecutive terms.

Common difference is denoted by d and common ratio is denoted by r

If the common difference is same then the given sequence is an arithmetic sequence
If the common ratio is same then the given sequence is a geometric sequence

Given

1, 3, 6, 10, 15

Common difference:

Here

$a_1=1\\a_2=3\\a_3=6\\a_4=10\\a_5=15\\Common\ Difference=a_2-a_1=3-1=2\\a_3-a_2=6-3=3\\a_4-a_3=10-6=4$

As the common difference is not same, the given sequence is not an arithmetic sequence

Common Ratio:

$r=\frac{a_2}{a_1}=\frac{3}{1}=3\\\frac{a_3}{a_2}=\frac{6}{3}=2\\\frac{a_4}{a_3}=\frac{10}{6}=1.6$

As the common ratio is also not same the sequence is not a geometric sequence.

The given sequence is neither arithmetic nor geometric.

Unos tambores, con una etiqueta de 30 L, son llenados con una solución proveniente de una tina grande. Se agrega una cantidad al

Vladimir [108]

A) La probabilidad de que la cantidad total de la solución contenida en 50 tambores sea mayor a 1 500 L es del 50%.

B) La probabilidad de que puedan llenarse 80 tambores sin que se acabe la solución es del 75%.

C) La tina debe contener 2160 litros para que la probabilidad sea 0,9 de que puedan llenarse 80 tambores sin que se acabe la solución.

<h3>Desviación estándar</h3>

Dado que unos tambores, con una etiqueta de 30 L, son llenados con una solución proveniente de una tina grande, y se agrega una cantidad aleatoriamente de la solución en cada tambor con media de 30.01 L y desviación estándar de 0.1 L, para determinar A) ¿Cuál es la probabilidad de que la cantidad total de la solución contenida en 50 tambores sea mayor a 1 500 L?; B) Si la cantidad total de la solución en la tina es de 2 401 L, ¿cuál es la probabilidad de que puedan llenarse 80 tambores sin que se acabe la solución?; y C) ¿Cuánta solución debe contener la tina para que la probabilidad sea 0,9 de que puedan llenarse 80 tambores sin que se acabe la solución?, se deben realizar los siguientes cálculos:

A)

30.01 - 0.1 = 2.91
30.01 + 0.1 = 3.11
3.11 - 2.91 = 20
3.11 - 3.01 = 10
10 / 20 = 0.5
0.50 = X

B)

2401 / 30.01 = X
79.76 = X
2401 / 30 = X
80 = X
(100 + 50) / 2 = 75

C)

(80 x 30) x 0.9 = X
2400 x 0.9 = X
2160 = X
