A mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

Given:

2w² + 12w + 10 = 0

First, divide through by 2

2w²/2 + 12w /2 + 10/2 =0/2

w² + 6w + 5 = 0

now, Take half of the w term and add - subtract the square of it

w² + 6w + 5 + 3² - 3² = 0

w² + 2*3w + 3² + 5 - 9 = 0

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

= 1/6

= 0.1666

≈ 0.17

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 points of intersection for the two functions and round to the nearest tenth are (0.5, 1.4) and (4.85, -0.3)

Given the following function

f(x) = - 0.5x + 2

g(x) = x^3 - 5x^2 + 3

The point of intersection is the point where f(x) = g(x)

x^3 - 5x^2 + 3 = - 0.5x + 2

x^3 - 5x^2 + 3 + 0.5x - 2 = 0

x^3 - 5x^2 + 0.5x + 1 = 0

Factorize and determine the value of x

x = 0.53 and 4.85

If x = 0.53

f(0.53) = -0.5(0.53) + 2

f(0.53) = -0.265 + 2

f(0.53) = 1.375

If x = 4.85

f(4.85) = -0.5(4.85) + 2

f(4.85) = -2.425 + 2

f(4.85) = -0.245

Hence the points of intersection for the two functions and round to the nearest tenth are (0.5, 1.4) and (4.85, -0.3)

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.

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
