The probability that it is less than 11.9 inches long will be 0.11304.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z-score is given as

z = (x - μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

A manufacturer knows that their items have a normally distributed length, with a mean of 14.2 inches, and standard deviation of 1.9 inches.

If one item is chosen at random.

Then the probability that it is less than 11.9 inches long will be

Then the z-score will be

z = (11.9 – 14.2) / 1.9

z = –1.21

Then the probability will be

P(x < 11.9) = P(z < –1.21)

P(x < 11.9) = 0.11304

Answer:

100 times stronger

Step-by-step explanation:

The Richter scale is a measurement system for the strength of Earthquakes. The most powerful Earthquakes are at 5-10, while the least powerful ones stay from 1-4.

This is how the Richter scale works:

An earthquake with a magnitude of 2 is 10 times more powerful than an earthquake with a magnitude of 1. Each number is 10 times more powerful than the last.

So, simple math tells us that Magnitude six is 10 times more powerful than magnitude five, and magnitude seven is 100 times more powerful than magnitude 5..

w-z can be expressed in ploar form as √2∠(7π/4)

Sometimes the expression A(cos(α)+i·sin(α)) is written as A·cis(α). I prefer the notation A∠α, because it is more compact.

 Given: w = √2∠(π/4)

 z = 2∠(π/2)

And you are asked to find the difference w-z in polar form.

In rectangular form, ...

 w = √2∠(π/4) = √2(1/√2 +i/√2) = 1 +i

 z = 2∠(π/2) = 2(0 +i·1) = 2i

Then the difference is ...

 w -z = (1 +i) -(2i) = 1 -i

You may notice this is the conjugate of w, so will have the opposite angle:

w - z = w* = √2∠(-π/4) = √2∠(7π/4)

In the terms used by the problem statement, ...

 w -z = √2(cos(7π/4) +i·sin(7π/4))

Answer:

Step-by-step explanation:

So if you look at the numerator the degree is 2, and if you look at the numerator of the denominator, it's 3. This means that the value of the denominator will grow faster than the numerator, so it will diverge.

To find the first 5 terms simply plug in 1, 2, 3, 4, and 5 as n

[tex]a_1=\frac{1^2-9}{1^3+3} = \frac{-8}{4} = -2}\\a_2 = \frac{2^2-9}{2^3+3} = \frac{-5}{11} = -\frac{5}{11}\\a_3 = \frac{3^2-9}{3^3+3} = \frac{0}{30} = 0\\a_4 = \frac{4^2-9}{4^64+3} = \frac{7}{67} = \frac{7}{67}\\a_5 = \frac{5^2-9}{5^3+3} = \frac{16}{128} = \frac{1}{8}[/tex]

Answer:

92.16

Step-by-step explanation:

solving the brackets first, -41..8 + 32..2 equals -9.6 in total. The bracket has a square around it so our answer would be the square of wat ever we get in the bracket meaning (-9.6)^2 which gives us 92.16

The consecutive two integers are 5 and 6

Linear equations

Let the two consecutive integers be (x+1) and (x). If twice the sum of two consecutive integers is 22 then;

2(x+1+x) = 22

x+x+1 =  22/2

2x + 1 = 11

Subtract 1 from both sides

2x = 11 - 1

2x = 10

x = 5

Hence the consecutive two integers are 5 and 6

x is 3 that is the number of hits

e = 2.71828 is the Euler number

μ is the mean in the given interval = 0.967

There is 5.72% probability that a randomly selected region had exactly three hits.

Let X be the random variable denoting the number of bombs hitting the selected sample.

The following formula determines the likelihood that x in a Poisson distribution corresponds to the number of successes of a random variable.

P(X = x) = e^₋μ × μˣ / (x)!

Here, X is the random variable denoting the number of bombs hitting the selected sample.

μ is the mean number of hits per region.

e is the constant value.

Since 535 bombs struck a total of 553 regions, the ratio of strikes per region to the total number of regions is 535 to 553.

μ = 535 / 553

μ = 0.967

Assume that we want to find the probability that a randomly selected region had exactly 3 hits.

which means, P(X = 3)

P(X = x) = e^₋μ × μˣ / (x)!

P(X = 3) = e^₋0.967 × (0.967)³/ (3)!

             = 0.057

There is approximately 5.72% probability that a randomly selected region had exactly three hits.

Answer:

x = 14

Step-by-step explanation:

110 + 5x = 180

-110 -110

5x = 70

divide by 5 on both sides

x = 14

to find y add 70 + 40 + missing angle = 2y

missing angle is 70 because 70+40+70 = 180

so 2y = 110

y = 55

Answer:

x=14

y=55

Step-by-step explanation:

5x and  110 form a straight line so they add to 180

5x+110 =180

5x = 180-110

5x = 70

Divide by 5

5x/5 = 110/5

x = 14

We know the exterior angle of a triangle is equal to the sum of the two opposite interior angles

40 + 5x = 2y

Substitute in 14 for x

40 +5(14) = 2y

40 + 70 = 2y

110 = 2y

Divide by 2

110/2 =2y/2

55 = y

Using the normal distribution, it is found that due to the greater z-score, Stewart caught the longer fish relative to the same specie.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

To find who caught the longer fish relative to the same specie, we need to find out who had the higher z-score.

Stewart caught a bluefish with a length of 322 mm, hence the parameters are as follows:

[tex]X = 322, \mu = 267, \sigma = 39[/tex]

The z-score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{322 - 267}{39}[/tex]

Z = 1.41

Gina caught a pompano with a length of 176 mm, hence the parameters are as follows:

[tex]X = 176, \mu = 155, \sigma = 28[/tex]

The z-score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{176 - 155}{28}[/tex]

Z = 0.75.

Hence Stewart caught the longer fish relative to the same specie.

The estimated probability for P(H) is 0.17.

Probability is the stream in mathematics that studies about the likeliness of an event to happen.

It is given that

Total number of times coin is flipped = 30

Total number of times the coin gave heads = 5

Total number of times the coin gave tails=25

The P(H) = Total no. of Heads /  Total outcomes

P(H) = 5 / 30
