If a shuttle was launched every day, about 1 failures would one expect in 300 years.

Finding an estimate or approximation—a value that can be used for a purpose despite the possibility of incomplete, uncertain, or unstable input data—is the process of estimation. Despite this, the value is still useful because it was created using the most up-to-date data.

Here,

There are about 110,000 days in 300 years, so the expected number of failures is about 10/11 ≈ 1.

This assumes the launch conditions are identical for each of the launches, or that whatever variation there might be has no effect on the probability. These are bad assumptions.

If a shuttle was launched every day, one might anticipate one failure every 300 years.

The probability that at least 1 of them is a universal donor 20.1%

A probability is a numerical representation of the possibility or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Mathematics' study of random events is known as probability, and there are four primary forms of probability: axiomatic, classical, empirical, and subjective. Since probability is the same as possibility, you might argue that it is the likelihood that a specific event will occur.

According to the given equation:-

The probability that at least one of every three is O-negative is 20.1%

Note that the question is unfinished. The following question is similar:

Type O-negative individuals can donate blood to anyone. In other words, O-negative blood can be transfused to any patient. Only 7.2% of Americans have blood that is O-negative. What is the likelihood that at least one of the ten Americans we randomly choose donating blood is a universal donor?

Detailed explanation:

7.2%, or 0.072, of the population has O-negative blood.

Probability of not being O-negative is equal to 1 - P(O-negative), which is 1 - 0.072, or 0.928.

Using the multiplication rule, calculate the likelihood that 10 persons are O-negative.

Probability that 10 is not zero = (P (not O-negative) ¹⁰ = (0.928) (0.928) ¹⁰ =0.4737

Therefore, the probability that at least one is O-negative is given by the formula: 1 - P(not O-negative) = 1 - 0.4737 = 0.5263.

P(at least 1 in 10 being O-negative) = 52.63% in percentage

to 3 arbitrary donors

likelihood of 3 not - (P) negative (not O-negative) ³ = (0.928) (0.928) ³ = 0.7991

As a result, the likelihood that at least 1 is O-negative is equal to 1 - P(3 not O-negative) = 1 - 0.7991 = 0.2009.

P(at least 1 out of 3 being O-negative) = 20.1% in percentage

Answer:

Step-by-step explanation: The number of yellow sweets is 28. Step-by-step explanation: Ratio of red to yellow sweets is 3:7. Total sweet is 40. total ratio is 3 + 7 = 10.

1260 tickets were sold on the first game

For the second game, the ratio of the number of sold tickets to number of unsold tickets is 13:2

Total ratio = 13+2 = 15

There were 240 unsold tickets for the second game. Let total number of tickets for the second game be x

This means that

240 = 2/15 × x

2x/15 = 240

2x = 15 × 240= 3600

x = 3600/2 = 1800

1800 tickets were sold for the second game. Assuming total number of tickets for the first game is equal to total number of tickets for the second game. Therefore,

Total number of tickets sold for the first game is 1800

The ratio of sold tickets to unsold tickets for the first game was 7:3.

Total ratio = 7+3 = 10

Number of sold tickets for the first game would be

7/10 × 1800 = 12600/10

Step-by-step explanation:

Answer:

21.475 minutes  

(Rounded) 21 minutes

Step-by-step explanation:

T(t)  =  TA  + (T0 - TA)e^(-kt)

We know that after 12 minutes...

140  = 70  + ( 165 - 70)e^(-k* 12)    

1 ) Simplify and subtract 70 from both sides

70 = ( 95)e^(-12k)      

2 ) Divide both sides by  25

70/95  = e^(-12k)      

3 ) Take the Ln of both sides

Ln (70/95) =  Ln e^(-12k)    

and we can write  Ln (70/95)  = (-12k)  Ln e

[ Ln e  =1, so we can ignore this  ]

4 ) Divide both sides by -12

Ln (70/95) / -12  = k  ≈   .02545

So...

5 ) We want to find this  125  =  70  + ( 165 - 70)e^(-.02545t)

6 ) 55 = (95)e^(-.02545*t)

7 ) 55/95  =  e^(-.02545*t)      take the Ln of both sides

8 ) Ln (55/95)  = Ln e ^(-.02545 *t)

9 ) Ln (55/95)  =  (-.02545 * t)  * Ln e

10 ) Ln (55/95) = -.02545 * t    

11 ) Ln (55/95) / (-.02545)  = t  ≈ 21.475 minutes

12 ) If we are rounding then it would be 21 minutes

Hope this helps! :)

What is Angles?

An angle is a figure in Euclidean geometry made up of two rays that share a common endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. Dihedral angles are these.

Given,

x°, (4z + 6)°, 2y° and 106°

Lets solve,

x° and 106°

From the co-interior  angle

x + y = 180°

x° + 106° = 180°

x = 180 - 106

x = 74°

by alternate exterior angle

x = 2y

Since we know about the value of x

we can write it as

74 = 2y

y = 74/2

y = 37°

Now by alternate interior angles

(4z + 6) = x

(4z + 6) = 74

4z = 74 - 6

4z = 68

z = 68/4

z = 17°

Hence, Value of x, y and z is 74°, 37° and 17° respectively

The area of the rectangle 81 square units and the perimeter of the rectangle is 36 units.

In this question, we have been given the rectangle with coordinates (3,7), (3,-2), (-6.-2) and (-6,7)

We need to find the perimeter and area of the rectangle.

Using distance formula we find the length and width of the rectangle.

d1 = √(-2 - 7)² + (3 - 3)²

d1 = √(-9)²

d1 = 9

And d2 = √(-2 + 2)² + (-6-3)²

d2 = √(-9)²

d2 = 9

d3 = √(7 + 2)² + (-6 + 6)²

d3 = 9

This means, the length and width of rectangle are equal i.e., 9 units.

So, perimeter would be,

P = 4 * 9

P = 36 units

And the area would be,

A = 9 * 9

A = 81 square units

Here, d-1 is the largest possible value of N.

Given info,

For an arbitrary Markov chain on a state space consisting of exactly d states, find (with proof) the largest possible positive integer n such that for some states i,j, we have p(n) ij > 0 but p(n) ij.

We will prove that N ≤ d - 1

In light of this, there are states I and j such that the path from I to j has at least N edges, which implies that the path from I to j has at least d edges.

However, since there are only d states, the distance between any two states can be no greater than d-1. N can't thus be bigger than d-1.

Now, d-1 is the largest possible N because if we take a look at a Markov chain, if I is between 1 and d, we can only move to state 2 and if I is already at state d, we can only move to state d-1. However, if I am already at state 1, we can only move to state 1 and if I am already at state 2, we can only move to state i+1.

This sample contains d-1 edges on the way from state 1 to d. N = d-1 hence holds in this situation.

Therefore, N can have a value as large as d-1.

Time, t = 6 years

To calculate the amount owed, we make use of the following formula

A = P + CI

Where

Compound interest, CI = P(1 + R)^t - P

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

In this question, the formula is given as

A = P(1 + r/n)^nt

Where

n = 12, i.e compounded monthly

Substitute the known values in the above equation

A = 5300 * (1 + 8%/12)^(6*12)

Express 8% as decimal

A = 5300 * (1 + 0.08/12)^(6*12)

Evaluate the sum

A = 5300 * (1.01)^(6*12)

Step-by-step explanation:

You want the volume of a prism with an L-shaped base.

The volume of a prism is given by ...

  V = Bh

where B is the area of the base, and h is the distance between bases.

The base is has an L-shape. Its area can be found by extending the horizontal line to divide the figure into two rectangles.

The top rectangle is 4cm × 5cm, so has an area of ...

  A = LW = (4 cm)(5 cm) = 20 cm²

The bottom rectangle is 9 cm × 3 cm, so has an area of ...

  A = LW = (9 cm)(3 cm) = 27 cm²

Then the total base area is ...

  B = (top rectangle area) + (bottom rectangle area)

  B = (20 cm²) +(27 cm²) = 47 cm²

Then the volume is ...

  V = Bh = (47 cm²)(10 cm) = 470 cm³

The volume of the prism is 470 cm³.
