(c)what is the probability that a randomly selected student is not majoring in nursing, criminal justice, or business technology? is this an example of empirical or theoretical probability?

Answers

The probability that a randomly selected student is not majoring in nursing, criminal justice, or business technology is 0.7.

What is Probability?

Probability is the study of random events and their outcomes. It is the likelihood that something will occur under given conditions. Probability is expressed as a number between 0 and 1, with 0 representing an impossibility and 1 representing a certainty. Probability theory provides the tools to calculate the likelihood of a given event, and can be used to make decisions when faced with uncertainty. Probability is a useful tool in many fields, including science, finance, medicine, and gaming.

This is an example of a theoretical probability, since it is based on theoretical data rather than actual observations. Theoretical probability is calculated by taking the number of favorable outcomes divided by the total number of possible outcomes. In this case, the number of favorable outcomes is the number of students who are not majoring in nursing, criminal justice, or business technology, and the total number of possible outcomes is the total number of students.

a. a b. b, c, d c. a, b d. a, b, c, d e c, d

Answers

Among the given sets of vectors, the sets that can be bases for ℝ³ are (a) (2, 0, 0), (4, 4, 0), (6, 6, 6) and (b) (3, 1, -3), (6, 3, 3), (9, 2, 4). The correct options are (a) and (b).

In order for a set of vectors to form a basis for ℝ³, they must satisfy two conditions: (1) The vectors must span ℝ³, meaning that any vector in ℝ³ can be expressed as a linear combination of the given vectors, and (2) the vectors must be linearly independent, meaning that no vector in the set can be expressed as a linear combination of the other vectors.

(a) (2, 0, 0), (4, 4, 0), (6, 6, 6): These vectors span ℝ³ since any vector in ℝ³ can be expressed as a combination of the form a(2, 0, 0) + b(4, 4, 0) + c(6, 6, 6). They are also linearly independent, as no vector in the set can be expressed as a linear combination of the others. Therefore, this set forms a basis for ℝ³.

(b) (3, 1, -3), (6, 3, 3), (9, 2, 4): These vectors also span ℝ³ and are linearly independent, satisfying the conditions for a basis in ℝ³.

(c) (4, -3, 5), (8, 4, 3), (0, -10, 7): These vectors do not span ℝ³ since they lie in a two-dimensional subspace. Therefore, they cannot form a basis for ℝ³.

(d) (4, 5, 6), (4, 15, -3), (0, 10, -9): These vectors do not span ℝ³ either since they also lie in a two-dimensional subspace. Hence, they cannot form a basis for ℝ³.

In conclusion, the correct options for sets of vectors that form bases for ℝ³ are (a) and (b)

the solid bounded by the elliptic cylinder 4x2 + z2 = 4 and the planes y = 0 and y = z + 2

Answers

By substituting the limits of integration and solving the definite integral, the volume of the solid is approximately 3.57 cubic units.

What is integration ?

Integration is a fundamental concept in calculus that deals with the problem of finding the total change in a quantity over a given interval. It is the reverse process of differentiation, which deals with finding the rate of change of a quantity.

We can think of slicing the solid into thin horizontal slices, each parallel to the y = 0 plane. The cross-section of each slice with the elliptic cylinder will be an ellipse. The area of each ellipse can be calculated using the formula for the area of an ellipse, which is πab, where a and b are the semi-major and semi-minor axes of the ellipse.

The semi-major axis of the ellipse is 2, and the semi-minor axis is √(4 - 4x^2) = √(4(1 - x^2)) = 2√(1 - x^2). So the area of each slice is A(x) = π(2)(2√(1 - x^2)) = 4π√(1 - x^2)

The height of each slice is dy = dz = dx, since the slices are parallel to the y = 0 plane and the height of each slice is equal to the change in y or z between two consecutive slices.

So, the volume of the solid is ,

∫ (4π√(1-x^2)) dx from x = -1/2 to x = 1/2

By substituting the limits of integration and solving the definite integral, the volume of the solid is approximately 3.57 cubic units.

An equilateral triangle with side lengths of 8.7 centimeters is shown. An apothem has a length of a and the radius has a length of 5 centimeters. The apothem and radius form a triangle with a base length of b. Which statements about finding the area of the equilateral triangle are true? Select three options

Answers

The image of the triangle is missing, so i have attached it.

Also, the options are;

A) The apothem can be found using the Pythagorean theorem.

B) The apothem can be found using the tangent ratio.

C) The perimeter of the equilateral triangle is 15 cm.

D) The length of the apothem is approximately 2.5 cm.

E) The area of the equilateral triangle is approximately 65 cm².

Answer:

Options A, B & D are true

Step-by-step explanation:

A) We are told that the triangle is an equilateral triangle.

Thus, the 3 sides equal 8.7 cm.

Now from the image, b is half of one of the sides.

Thus, b = 8.7/2 = 4.35 cm

Now, we want to find the apothem "a".

Using Pythagoras theorem, we have;

a² + 4.35² = 5²

a² = 25 - 18.9225

a² = 6.0775

a = √6.0775

a ≈ 2.5 cm.

Thus, option A is true as pythagoras theorem was able to calculate the apothem "a"

B) since the main triangle is equilateral, it means each angle is 60°.

Now,the radius line from one corner point to the centre will divide the 60° angle into 2 equal parts.

Thus, the angle made by the radius line with the base of the triangle is 60/2 = 30°

Now,from tangent ratios, we know that;

Opposite/Adjacent = tan θ

In the small triangle, opposite is apothem "a" while adjacent is b = 4.35 cm

Thus;

a/4.35 = tan 30

a = 4.35 tan 30

a ≈ 2.5 cm.

Thus, option B is correct as Tangent ratio can be used to find the apothem

C) The perimeter of equilateral triangle = 3x

Where x is length of one side.

One side is 8.7 cm

Thus, perimeter = 3 × 8.7 = 26.1 cm

Thus option C is not correct.

D) From calculations above, we saw that in both options A & B, the apothem is approximately 2.5 cm.

Thus, option D is true.

E) Area of triangle is;

A = ½ × base × height

Base = 8.7 cm

To get height, we will use trigonometric ratio. Thus;

h/8.7 = sin 60°

h = 8.7 sin 60°

Thus;

A = ½ × 8.7 × 8.7 sin 60°

A = 32.77 cm²

Thus is not equal to 65 cm². Thus, option E is not correct.

Answers

Answer:

Answer C

Step-by-step explanation:

This is because acute triangles have angles that are under 90 degrees and Option A would be true to what you are trying to make false and B & D are false because they have angles that go over 90 degrees.

The other statements that provide contradiction to the given expression are option (B) and (C).

What is a acute triangle?

An elementary polygon having three sides and three vertices is a triangle. There are three internal angles since it has three sides. An acute angle is one that ranges in measurement from 0° to 90°. A form of triangle called an acute triangle has acute angles at each of its three internal angles.

In the option (A),

the three angles could be 30°, 30°, and 30°.

These angles contradict the basic property of triangle.

Which is sum of all the triangles are 180°.

In the option (B),

the three angles could be 30°, 60°, and 90°.

The above angles hold the property of an acute triangle.

In the option (C),

The three angles could be 30°, 70°, and 80°.

The above angles also hold the property of an acute triangle.

The probability that house sales will increase in the next 6 months is estimated to be 0.25. The probability that the interest rates on housing loans will go up in the same period is estimated to be 1.74. The probability that house sales or interest rates will go up during the next 6 months is estimated to be 0.89. The event that an increase in house sales and no increase in house sales will occur in the next 6 months are:___________

Answers

The probability of an increase in house sales and no increase in house sales will occur in the next 6 months is 0.09.

The event that an increase in house sales and no increase in house sales will occur in the next 6 months are:

1) The probability of house sales to increase in the next 6 months is estimated to be 0.25, then the probability of no increase is 0.75.

2) The probability that house sales or interest rates will go up during the next 6 months is estimated to be 0.89,

then the probability that interest rates will go up is 0.89 - 0.25

= 0.64.

3) The probability of an increase in house sales and no increase in interest rates

= Probability of increase in house sales * Probability of no increase in interest rates

= 0.25 * (1 - 0.64)

= 0.25 * 0.36

= 0.09

Therefore, the probability of an increase in house sales and no increase in house sales will occur in the next 6 months is 0.09.

what is permutation?

The permutation of a set in mathematics is essentially the rearranging of its elements if the set is already ordered, or the arrangement of its members in a linear or sequential order. The act of altering the linear order of an ordered set is referred to as a "permutation" in this context. The mathematical calculation of the number of possible arrangements for a given set is known as permutation. Permutation, in its simplest form, refers to the variety of possible arrangements or orders. The placement of the elements matters with permutations. The placement of items in a specific order is known as a permutation. Here, the set's components are sorted in either chronological order or linear order. like in the case of

find the value of k for which the roots of the quadratic equation 5x-10x+k=0 are real and equal

Answers

The roots of the given equation is real and equal.

Given , 5\(x^{2} \\\) - 10x+ k=0

The quadratic equation is b² - 4ac = 0

Here, a= 5, b= -10, c= k

substitute in b² - 4ac = 0

(-10)² - 4 * 5* k =0

100 - 20k =0 , let this be equation (1)

100 = 20k

k = \(\frac{100}{20}\)

k = 5.

now, substitute  k= 5 in equation (1)

100 -20k = 0

100 - 20*5 = 0

100 - 100 = 0

Therefore, the given equation is real and equal .

arcsin (-1)
compute the exact value

Answers

–π/2 is the exact value of arcsine (-1).

What is arcsine?

The six main inverse trigonometric functions include arcsin. It is the sine function's inverse trigonometric function. The mathematical symbol for arcsin, commonly known as inverse sine, is arcsin x or sin-1x (read as sine inverse x). Sin-1x is not the same as (sin x)-1; that is, sin-1x is not the reciprocal function of sin x. This is an important distinction to make. We may use the six inverse trigonometric functions arccos, arcsin, arctan, arcsec, arccsc, and arccot to calculate angles. Arcsin x calculates the angle that corresponds to the right-angled triangle's perpendicular to hypotenuse ratio. We shall examine the idea of arcsin in this article and determine its formula. We'll also talk about the domain and range.

show me the step and answer using spss A consumer agency wanted to estimate the difference in the mean amounts of caffeine in two brands of coffee.The agency took a sample of 15 one-pound jars of Brand I coffee that showed the mean amount of caffeine in these jars to be 80 milligrams per jar with a standard deviation of 5 milligrams.Another sample of 12 one-pound jars of Brand Il coffee gave a mean amount of caffeine equal to 77 milligrams per jar with a standard deviation of 6 milligrams.Construct a 95% confidence interval for the difference between the mean amounts of caffeine in one-pound jars of these two brands of coffee. Assume that the populations are normally distributed and the standard deviations of the two populations are equal.Interpret your answer.

Answers

At 95% confidence-level, the true difference between the mean amount of caffeine in the two brands of coffee jars is between -0.3641 mg/jar and 6.3641 mg/jar.

Sample size of Brand I coffee jars (n₁) = 15

Mean of the sample of Brand I coffee jars (x₁-bar) = 80

Standard deviation of the sample of Brand I coffee jars (s₁) = 5S

ample size of Brand II coffee jars (n₂) = 12

Mean of the sample of Brand II coffee jars (x₂-bar) = 77

Standard deviation of the sample of Brand II coffee jars (s₂) = 6

To construct a 95% confidence interval for the difference between the mean amounts of caffeine in one-pound jars of these two brands of coffee, we use the formula given below:

CI = (x₁-bar - x₂-bar) ± tα/2 * SE where

CI = Confidence Interval

x₁-bar = Sample mean of Brand I coffee jars

x₂-bar = Sample mean of Brand II coffee jars

s₁ = Standard deviation of the sample of Brand I coffee jars

s₂ = Standard deviation of the sample of Brand II coffee jars

n₁ = Sample size of Brand I coffee jars

n₂ = Sample size of Brand II coffee jars

SE = Standard Error of the difference between mean

s= √(s1^2/n1 + s2^2/n2)tα/2

 = t-score for 95% confidence interval with (n1+n2-2) degrees of freedom

  = t0.025

Here, the degrees of freedom = (15+12-2)

                                                  = 25 degrees of freedom

Using the t-distribution table for 25 degrees of freedom at a 95% confidence level, we get t0.025 as 2.0592.

Substituting the values in the formula, we get,

SE = √(s₁²/n₁ + s₂²/n₂)

    = √(5²/15 + 6²/12)

    = √(25/15 + 36/12)

     = √(5/3 + 3)

      = √(8/3)

      = 1.6325CI

      = (80 - 77) ± 2.0592 * 1.6325

      = 3 ± 3.3641

The 95% Confidence interval for the difference between the mean amounts of caffeine in one-pound jars of these two brands of coffee is (3-3.3641, 3+3.3641) or (-0.3641, 6.3641) mg/jar.

At 95% confidence level, we can conclude that the true difference between the mean amount of caffeine in the two brands of coffee jars is between -0.3641 mg/jar and 6.3641 mg/jar.

This means the difference between the mean amount of caffeine in the two brands of coffee jars is statistically significant and we can reject the null hypothesis.
