For an electric network with three switches ( two are in series and one in parallel), the probability that the system is working is equal to the 0.644 or 64.4 %.

We have, an electric network has 3 switches aligned as present in above figure. Switches present in upper side in network or in series are switch 1 and switch 2 and switch present in parallel is switch 3. The probability that one out of three is turn on = 60% = 0.60

We have to determine probability that the system is working. System is working when all switches are on. Letvus consider the events,

A = Switch 1 is turn on

B = Switch 2 is turn on

C= Switch 3 is turn on

Now, probability that switch 1 is turn on P( A) = 0.60

Probability that switch 2 is turn on P( B)

= 0.60

Probability that switch 3 is turn on P(C)

= 0.60

We know if two events A and B are independent then, we have P(A∩B) = P(A) × P(B)

Here, Switch 1 and switch 2 are independent so, P( A∩B) =0.60 × 0.60

= 0.36

Probability that the system is working =

[(switch 3 is turn on ) or (switch 1 is turn on and switch 2 is turn on)]

= P( C∪( A∩B))

= P(C) + P(A∩B ) - P ( C∩ (A∩B))

= 0.60 + 0.36 - P(C) × P(A∩B)

= 0.96 - 0.6 × 0.36

= 0.96 - 0.216

= 0.644

Hence, required probability is 0.644.

Answer: The value of f(-1) is equal to 5(-1)^2 + (-1) + 4 = -5 + (-1) + 4 = -2

Step-by-step explanation:

To evaluate f(-1), we substitute -1 for x in the function f(x)=5x^2+x+4. This gives us f(-1)=5(-1)^2+(-1)+4. We simplify this by applying the exponent first, so (-1)^2=1. Then we substitute the result in the function, which gives us f(-1)=5(1)+(-1)+4. Now we can simplify it by adding and subtracting the values which gives us f(-1)=5+(-1)+4=8.

Answer:

5)

x=13.856

y=8

6)

u=4

v=3.464

Step-by-step explanation:

5)

y=hypothesis * sin(opposing angle)/sin(angle opposite of hypothesis)

y = 16*sin(30)/sin(90)

y=8

x=hypothesis * sin(opposing angle)/sin(angle opposite of hypothesis)

x=16*sin(60)/sin(90)

x=13.856

6)

sinA/(opposite of angle A) = sinB/(opposite side of angle B) = sinC/(opposite of side of angle C)

sin(90)/u= sin(30)/2

u *sin(30) = 2* sin(90)

u *sin(30) = 2

u=2/sin(30)

u=2/0.5

u=4

sin(60)/v= sin(30)/2

v *sin(30) = 2* sin(60)

v *sin(30) = 2 * 0.866

v * sin(30) = 1.73

v = 1.73/sin(30)

v = 3.464

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[5] x = 8 and y =  13.856

[6] v = 4 and u = 3.464

-------------------------------------------------------------------------------------------------------------

[5]

sin60° = x/16 = 1/2

x = 16/2 = 8

There are nC2 different votes possible, where n is the number of bands on the list and nC2 represents the number of ways to choose 2 bands out of n.

To calculate nC2, we can use the formula for combinations, which is given by n! / (2! * (n-2)!), where ! represents factorial.

Let's say there are m bands on the list. The number of ways to choose 2 bands out of m can be calculated as m! / (2! * (m-2)!). Simplifying this expression further, we get m * (m-1) / 2.

Therefore, the number of different votes possible is m * (m-1) / 2.

In the given scenario, we don't have the specific number of bands on the list, so we cannot provide an exact number of different votes. However, you can calculate it by substituting the appropriate value of m into the formula m * (m-1) / 2.

After evaluating the double integral, the result, 0.27, is determined by the stated statement.

In mathematics, an integral is either a number representing the region beneath a function's graph over a certain interval or maybe a new function, the inverse of which comprises the original result (indefinite integral). The value produced after integrates or adding the words of a function that is split into an unending number of terms is referred to as an integral value in general.

The double integral is an example.

\(\iint_D\left(x^2+2 y\right) d A\) where d is enclosed by the lines y = x & y = x³.

In the region D, x varies from 0 to 1, and y varies from y = x³ to y = x

\(\therefore \iint_D\left(x^2+2 y\right) d A=\int_{x=0}^1 \int_{y=x^3}^x\left(x^2+2 y\right) d y d x\)

\(=\int_{x=0}^1\left[x^2 y+y^2\right]_{x^3}^x d x\)

\(=\int_{x=0}^1\left[x^2\left(x-x^3\right)+\left[x^2-\left(x^3\right)^2\right]\right] d x=\int_{x=0}^1\left[x^3-x^5+x^2-x^6\right] d x\)

\(\left.=\frac{x^4}{4}-\frac{x^6}{6}+\frac{x^3}{3}-\frac{x^7}{7}\right]_0^1\)

The measurement that is closest to the value of x, in centimeters, is given as follows:

14.3.

In this problem, we have a right triangle, in which the legs, which are the sides between the angle of 90º, are of 11.9 cm and 7.9 cm.

Then the hypotenuse x, which is the segment connecting both legs, is obtained using the Pythagorean Theorem.

The Pythagorean Theorem states that the measure of the hypotenuse squared is equals to the sum of the squares of the measures of each side.

Then the length of x is calculated as follows:

x² = 11.9² + 7.9²

x = square root of (11.9² + 7.9²)

x = 14.28.

Closest to 14.3, rounding to the nearest tenth, meaning that the third option is correct.  

We suppose that 11.9 cm and 7.9 cm are the measures of the legs.

The height of the hot air balloon is 1514.54 feet approximately.

Step-by-step explanation:

Consider the provided information.

The angle of elevation from the top of a 95-foot tall building to a hot air balloon in the sky is 76. If the horizontal distance between the building and the hot air balloon is 354 feet, find the height of the hot air balloon

The figure is shown below:

Let the height of the balloon is AD, the height of the building is BC.

Draw a line BE parallel to CD.

Therefore, AD=x+95, BC=95 and BE=CD=354 ft

Now in triangle \(ABE\).

\(\tan\theta=\dfrac{\text{Opp}}{\text{Adj}}\)

\(\tan76^{\circ}=\dfrac{AE}{BE}\)

\(AE\approx 4.01\times 354\)

\(AE\approx 1419.54\)

The height air balloon is 1419.54+95 =1514.54 ft

Hence, the height of the hot air balloon is 1514.54 feet approximately.

Solution a needed 70 ounces and solution b needed 50 ounces

What does "1 ounce" mean?

One ounce weighs 437.5 grains or 28.349 grams and is a sixteenth of a pound (avoirdupois) of weight.

One ounce, abbreviated "oz," equals 480 grains, or 31.103 grams, and is one-twelfth of a Troy or Apothecaries' pound in weight. abbreviation for fluid ounce. a tiny amount or percentage.

So, let x=the of ounces of the 50% acid solution. The total volume after both are mixed is 100 ounces so the amount of the 20% solution will be 120-X. The equation will therefore be:

50% * x + 20% * (100-x) = 41% * 100

Dropping the ‘%’ we get

50x + 2000 - 20x = 4100

30x = 2100

x = 2100/30 = 70

Hence 70 ounces will be needed

Solution a = 70 ounces

Step-by-step explanation:

Perimeter: the boundary that surrounds a shape

1) Find the perimeter of the semicircle using this formula: \(\frac{1}{2} *2\pi r\), where \(r\) is the radius, and π is 3.14 (according to the question).

1.1) We need to find the radius first.

Radius = Diameter ÷ 2

So, 10 ÷ 2 = 5

1.2) Input the values into the semicircle formula.

\(\frac{1}{2} *2(3.14)(5)\)

1.3) solve for the perimeter of the semicircle.

\(\frac{1}{2} *31.4\)

= 15.7

2) Find the perimeter of the triangle and the rectangle.

= \(6 + 12.2 + 14 + 14\)

= 46.2

3) Add them.

= \(46.2 + 15.7\)

= 61.9 ft

3) Round the answer (61.9) to the nearest hundredth (according to the question).

= 61.90 ft

As per the total length of the arc of a semicircle, the outer perimeter of this figure is 61.9 feet.

A semicircle that has a radius of 'r' units, has the total length of it's arc is

= πr units

In the given figure, the semicircle has a diameter = 10 feet.

Therefore, the radius of the semicircle

= 10/2 feet

= 5 feet

Now, the total length of it's arc is

= πr units

= 3.14 × 5 feet

= 15.7 feet

Therefore, the outer perimeter of this figure is

= (12.2 + 6 + 14 + 15.7 + 14) feet

= 61.9 feet
