The complement of event E, E°, is {14, 15, 16, 17}. The probability of event E° is 1/3, as all outcomes in the sample space are equally likely, with a probability of 1/12.

E° is the complement of event E. It is the set of all outcomes that are not in event E and can be expressed as E° = {14, 15, 16, 17}.The probability of event E° is calculated by summing the probabilities of all outcomes in the event, P(E°) = P(14) + P(15) + P(16) + P(17). Since all outcomes in the sample space are equally likely, the probability of each outcome is 1/12. This means that the probability of event E° is calculated as follows:

P(E°) = 1/12 + 1/12 + 1/12 + 1/12 = 4/12 = 1/3.

Therefore, The complement of event E, E°, is {14, 15, 16, 17}. The probability of event E° is 1/3, as all outcomes in the sample space are equally likely, with a probability of 1/12.

Answer:

Step-by-step explanation:

Since the sequence is an arithmetic sequence

For an nth term in an arithmetic sequence

A(n) = a + ( n - 1)d

where a is the first term

n is the number of terms

d is the common difference

From the question

d = 6

a = 2

n = 12

So the 12th term of the sequence is

A(12) = 2 + (12-1)6

= 2 + 11(6)

= 2 + 66

Answer:

y = -x + 1

Step-by-step explanation:

We're putting it into the form y=mx+b where m is the slope, and b is the y-intercept.

When two lines are parallel, they have the same slope, so the slope is going to be -1.

New equation: y = -x + b.

Now, you know that (4, -3) is a solution so you can plug in x = 4 and y = -3, then see what value of b make the equation true.

-3 = -4 + b

add 4 to both sides

1 = b

This means that the equation is y = -x + 1

Answer:

Twenty - percent pounds

Answer:

Because they are both using (g units rates).

Step-by-step explanation:

The required value of  b is 24 cm.

Given that, in a right-angled triangle, hypotenuse = 26 cm, perpendicular = 10 cm and base = b cm

Pythagoras theorem states that \(hypotenuse^{2} = base^2+perpendicular^{2}\).

That implies, \(26^2 = b^2+10^2\).

By substituting the square values gives,

676 = \(b^2\) + 100.

By subtracting 100 from both sides gives,

576 = \(b^2\).

The above equation can be expressed as

\(24^2 = b^2\)

By taking square root on both sides gives,

24 = b

Therefore, the required value of  b is 24 cm.

Answer:

While statistics are extremely valuable, they are also notorious for being a means that people use to make false and misleading arguments. Also far too often statistics are obtained by taking a sample from a larger group and assuming the whole group has the same characteristics as the sample.

A sample provides a smaller set of the population for review, that delivers data that is useful to represent the whole population. Surveying a smaller sample, as opposed to the entire population, can save precious time for researchers and offer urgent data.

(a) The probability of at most 4 customers arriving in any given minute is 0.835.
(b) The probability of at least 3 customers arriving in an interval of 2 minutes is 0.668.

Step by step explanation:
(a) To find the probability of at most 4 customers arriving in any given minute, we need to use the Poisson Distribution formula: P(X ≤ x) = Σ (e-λ λk) / k!
where λ is the mean number of customers arriving in one minute, which is 1.5.
Therefore, P(X ≤ 4) = Σ (e-1.5 (1.5)k) / k! = 0.835.

(b) To find the probability of at least 3 customers arriving in an interval of 2 minutes, we need to use the same Poisson Distribution formula.
This time, λ = 3 (the mean number of customers arriving in two minutes).
Therefore, P(X ≥ 3) = 1 - Σ (e-3 (3)k) / k! (where k ranges from 0 to 2)
= 1 - (0.224 + 0.452 + 0.224) = 0.668.

P(even) = 2/4 = 1/2 (there are 2 cards with even numbers out of 4)

Therefore,

P( 1 or even) =P(1) + P(even)

= 1/4 + 1/2

Answer:

1921.68 \(ft^{3}\)

Step-by-step explanation:

V = pi*r*r*h

= 3.14*6*6*17

= 1921.68

The radius of the circle is approximately 10.17 units (rounded to two decimal places).

To find the radius of the circle, we need to use the formula that relates the central angle to the length of the arc and the radius of the circle. The formula is given as:

arc length = radius x central angle

In this case, the arc length is given as 24.4 and the central angle is given as 2.4 radians. Substituting these values in the formula, we get:

24.4 = r x 2.4

Solving for r, we get:

r = 24.4 / 2.4

r ≈ 10.17

The maximum area is the highest possible area of the fence

The maximum area is 100 squared units

The perimeter is given as:

\(P = 40\)

This is calculated as:

\(P=2 \times (L + W)\)

So, we have:

\(2 \times (L + W) =40\)

Divide both sides by 2

\(L + W =20\)

Make L the subject

\(L =20 -W\)

The area of the fence is:

\(A = L \times W\)

So, we have:

\(A = (20 -W) \times W\)

\(A = 20W -W^2\)

Differentiate

\(A' = 20 -2W\)

Set to 0

\(20 -2W = 0\)

Solve for W

\(2W = 20\)

\(W = \frac{20}{2}\)

\(W = 10\)

Recall that:

\(A = (20 -W) \times W\)

\(A = (20 -10) \times 10\)

\(A = (20 =10) \times 10\)

\(A = 100\)

Hence, the maximum area is 100 squared units

Answer:

El precio de cada kilogramo de naranja y de manzana es 0.9 soles y 2 soles respectivamente.

Step-by-step explanation:

Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.

Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.

En este caso, se debe plantear un sistema de ecuaciones. Se determinan las variables:

Juan el primer día gastó 8,90 soles en total al comprar 1 kg de naranjas y 4 kg de manzanas; y el segundo día gastó 24,50 soles al comprar 5 kg de naranjas y 10 kg de manzanas. Entonces el sistema de ecuaciones a resolver es:

\(\left \{ {{x+4*y=8.90} \atop {5*x+10*y=24.50}} \right.\)

Se decide resolver el sistema a través del método de sustitución, que consiste en despejar una de las incógnitas en una de las ecuaciones y sustituir su valor en la siguiente. En este caso despejando la variable x de la primera ecuación se obtiene:

x= 8.90 - 4*y

Reemplazando esta expresión en la segunda ecuación se obtiene:

5*(8.90 -4*y) + 10*y=24.50

Resolviendo se obtiene:

5*8.90 -5*4*y + 10*y=24.50

44.5 -20*y + 10*y=24.50

-20*y + 10*y=24.50 -44.5

-10*y= -20

y= (-20)÷ (-10)

y= 2

Reemplazando el valor de y obtenido en la expresión x= 8.90 - 4*y se obtiene:

x= 8.90 - 4*2

x= 8.90 - 8

x=0.9

The latest time for pickup, found by converting the 150 minutes maximum time provided by the school, from minutes to hours is about 5:45 pm

Minutes can be converted into hours by dividing the number of minutes by 60, which is the number of minutes in an hour.

The time that school ends = 3:15 pm

The latest time for pick up after school care = 150 minutes after school ends

Therefore, the latest time for pick up after school care = 3:15 pm + 150 minutes

60 minutes = 1 hour

150 minutes = (1/60) × 150 = 2.5

The latest for pick up = 3:15 pm + 2.5 hours = 5:45 pm

An independent basic service set (IBSS) does not consist of any access points.

In an IBSS, devices such as laptops or smartphones connect with each other on a peer-to-peer basis, forming a temporary network. This type of network can be useful in situations where there is no existing infrastructure or when devices need to communicate with each other directly.

Since an IBSS does not involve any access points, it is not limited by the number of access points. Instead, the number of devices that can be part of an IBSS depends on the capabilities of the devices themselves and the network protocols being used.

To summarize, an IBSS does not consist of any access points. Instead, it is a network configuration where wireless devices communicate directly with each other. The number of devices that can be part of an IBSS depends on the capabilities of the devices and the network protocols being used.
