The probability that out of four containers chosen at random, less than two are nonconforming is 0.986.

Given that the plastic milk containers are produced by a machine that runs continuously.

If 5 percent of the containers produced are nonconforming, we need to determine the probability that out of four containers chosen at random, less than two are non-conforming.

Probability of nonconforming = 5% = 0.05

Probability of a conforming container = 1 - Probability of nonconforming = 1 - 0.05 = 0.95

Let X be the number of nonconforming containers out of four containers chosen at random. Since there are only two outcomes (conforming and nonconforming), we can model the situation with a binomial distribution.

The probability mass function of a binomial distribution is given by:

P(X = x) = nCx * p^x * (1-p)^(n-x)

Where nCx = n! / (x! * (n-x)!) is the binomial coefficient.

Therefore, we can write the probability of less than two nonconforming containers as:

P(X < 2) = P(X = 0) + P(X = 1)

P(X = 0) = 4C0 * (0.05)^0 * (0.95)^4 = 0.8145

P(X = 1) = 4C1 * (0.05)^1 * (0.95)^3 = 0.1715

P(X < 2) = 0.8145 + 0.1715 = 0.986

Therefore, the probability that out of four containers chosen at random, less than two are nonconforming is 0.986.

Correct answer:

The rational equation for the value of x has no real solution

From the question, we have the following parameters that can be used in our computation:

g(x) = (x² - 2x + 15)/(x + 3)

To solve the rational equation for the value of x, we set the equation to 0

So, we have

(x² - 2x + 15)/(x + 3) = 0

This gives

x² - 2x + 15 = 0

Checking if the equation has a real solution, we have

d = b² - 4ac

So, we have

d = (-2)² - 4 * 1 * 15

Evaluate

d = -56

This value is less than 0

This means that the equation has no real value

The variable data refers to the list [10, 20, 30]. After the statement data[1] = 5, data evaluates to [10, 5, 30]. A list is one of the compound data types that Python provides. Lists can contain items of different types, but they are usually all the same type.

Lists are mutable sequences, meaning that their elements can be changed after they have been created. Lists can be defined in several ways, including by enclosing a comma-separated sequence of values in square brackets ([ ]).

The elements of a list can be accessed using indexing, with the first element having an index of 0. The second element has an index of 1, the third element has an index of 2, and so on. To change the value of an element in a list, you can use indexing with an assignment statement.

For example, the statement `data[1] = 5` changes the second element of the `data` list to 5. Therefore, after this statement, the `data` list will be `[10, 5, 30]`.

ANSWER

The short piece is 10 meters long and the long piece is 33 meters long

EXPLANATION

Let the length of the shorter piece be x.

Let the length of the longer piece be y.

We have that the total length of the banner is 43 meters. This means that:

x + y = 43 ___(1)

The short piece is 23 meters shorter than the long piece. This means that:

x = y - 23 _____(2)

Now, we have a system of two simultaneous equations:

x + y = 43

x = y - 23

We can solve this by substitution.

Substitute the second equation into the first equation.

That is:

y - 23 + y = 43

Collect like terms:

y + y = 43 + 23

2y = 66

Divide through by 2:

y = 66 / 2

y = 33 m

Recall that:

x = y - 23

Therefore:

x = 33 - 23

x = 10 m

Therefore, the short piece is 10 meters long and the long piece is 33 meters long.

Answer:

area of the rectangle =length *breadth

=14*5=70sq.ft

diameter =6ft

radius =3ft

area of the semi circle =1/2πr^2

=1/2*22/7*3*3=14.142sq.ft

area of the figure =area of the rectangle +area of the semi circle =70+14.142=84.142sq.ft

Answer:

≈ 84.14 ft²

Step-by-step explanation:

The figure is composed of a rectangle and a semicircle, so

A = area of rectangle + area of semicircle

   = lb + \(\frac{1}{2}\)πr²

diameter of circle = 14 - (4 + 4) = 14 - 8 = 6 , then radius r = 3

A = (14 × 5) + (0.5 × π × 3² )

   = 70 + 4.5π

In Problem 1, the measure of each marked angle is as follows:292º, -112º, -282º, -46º, 380º, 96º, 326º, 508º, and 790º.In Problem 2, the angles indicated by the letters in the given figure are as follows:c = 65º, d = 95º, e = 65º, f = 95º, g = 85º, and h = 85º.

Problem 1:The measures of the marked angles are as follows:(7x + 19)º and (-3x + 5)º are supplementary angles since they are the interior angles on the same side of the transversal "V Vest".

Therefore, we can say: (7x + 19)º + (-3x + 5)º = 180º Simplifying, 7x + 19 - 3x + 5 = 180

Combine like terms and solve for x: 4x + 24 = 180 4x = 180 - 24 4x = 156 x = 39 Now substitute x = 39 in the given expressions and find the value of each angle.

(7x + 19)º = (7 × 39 + 19)º = 292º(-3x + 5)º

= (-3 × 39 + 5)º = -112º(-8x + 30)º = (-8 × 39 + 30)º

= -282º(32 - 2x)º = (32 - 2 × 39)º = -46º(10x - 10)º

= (10 × 39 - 10)º = 380º(2x + 18)º = (2 × 39 + 18)º = 96º(8x + 14)º

= (8 × 39 + 14)º = 326º(12x + 40)º = (12 × 39 + 40)º

= 508º(20x + 10)º = (20 × 39 + 10)º = 790º

Therefore, the measures of the marked angles are:292º, -112º, -282º, -46º, 380º, 96º, 326º, 508º, and 790º.Problem 2:The angles indicated by the letters in the given figure are as follows: Angle c: Corresponding angles with respect to the parallel lines n and m are equal. Therefore, we can say: c = 65º.Angle d: Vertically opposite angles are equal. Therefore, we can say: d = 95º.

Angle e: Alternate interior angles with respect to the parallel lines n and m are equal. Therefore, we can say: e = 65º.Angle f: Corresponding angles with respect to the parallel lines n and m are equal. Therefore, we can say: f = 95º.Angle g: Interior angles on the same side of the transversal are supplementary. Therefore, we can say: g = 180º - 95º = 85º.Angle h: Vertically opposite angles are equal. Therefore, we can say: h = 85º.

The probability of committing a Type II error when the mean difference is 55 is 1.

The concept of power in statistical testing is important for understanding the reliability of results. When the power of a statistical test is zero, it means that the test is unable to detect the difference between the means of two groups, even if there is a real difference.

In the given scenario, the mean is 52, the sample size is 25, and the standard deviation is 2.

This means that if the true mean difference between two groups is 55, there is a 100% chance that the test will not detect it. The probability of committing a Type II error is directly related to the power of a statistical test.

The higher the probability of committing a Type II error, the lower the power of the test.

Therefore, it is important to consider the power of a statistical test when interpreting results.

B. 154 ft

Step-by-step explanation:

From the given drawing of the right triangle formed by the measure of the angle to the top of the building, 64°, the height of the building, 'h', and their distance from the bottom of the building, 75 ft., we have;

The reference angle of the right triangle = The given 64° angle

The adjacent leg length to the reference angle = 75 ft.

The opposite leg length to the reference angle  The height of the building

From the given information, the trigonometric ratio we can use to find the height is the tangent of the reference angle, given as follows;

\(tan (Reference \, angle) = \dfrac{Opposite \ leg \ length}{Adjacent \ leg\ length}\)

Therefore, we have;

\(tan (64^{\circ}) = \dfrac{The \ height \ of \ the \ building, h}{75 \, ft.}\)

The height of the building, h = 75 ft. × tan(64°) = 153 feet \(9\dfrac{9}{32}\) inches

Therefore, the height of the building ≈ 154 feet.

Answer:

154 ft

Step-by-step explanation:

tan64° = \(\frac{h}{75ft}\)

h = tan64° * (75ft)

h = 2.0503038416 * 75

h = 153.77278812 ft or 154 ft rounded to the nearest foot
