Answer:D

Step-by-step explanation:

The solution is: x = +/- √7 and x = +/- i √2  are the solutions of the equation x^4 - 5x^2 - 14 = 0.

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

here, we have,

given that,

we have to factorize the equation,

The given equation is

x^4 - 5x^2 - 14 = 0

To factor this expression, we can change variables to make easier to see the solution.

x^4 = y^2

and

x^2 = y

Applying the change, we have

y^2 - 5y - 14 = 0

Now, you can observe that to factor this expression, we just need to find two number which product is 14 and which difference is 5, such numbers are 7 and 2.

y^2 - 5y - 14 = 0

or, (y-7) ( y+2) = 0

However, remember that , y = x^2

so, (x^2-7) ( x^2+2) = 0

Applying the zero property, we have

x = +/- √7

and x = +/- i √2

As you can see, the equation has two real solutions and two complex solutions.

Therefore, the right answer is the last choice.

The equations that has the solution x = all real numbers is 5(3x)+ 7x = 3x + 15 - x and 5(3x) + 7x = 3x + 10 - x,

Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the two equations 3x + 5 and 14, which are separated by the 'equal' sign, make up the equation 3x + 5 = 14.

A formula that expresses the connection between two expressions on each side of a sign. Typically, it has a single variable and an equal sign.

Here given equations,

5(3x) + 6x = 3x + 15 + 2x

15x + 6x = 3x + 15 + 2x

15 x + 6x - 3x -2x = 15

16 x = 15

x = 15/16

5(3x).+ 7x = 3x + 15 - x

15 x + 7x = 3x + 15 - x

15 x + 7x - 3x + x = 15

22x - 3x + x = 15

20 x = 15

x = 15/20

x = 3/4

5(3x) + 7x = 3x + 10 - x

15x + 7x - 3x + x = 10

20x = 10

x = 10/20

x = 1/2

5(3x) + 7x = x + 15 - 3x

15x +7x - x + 3x = 15

24x = 15

x = 15/24

x = 5/8

Therefore the equations that has the solution x = all real numbers are :

5(3x).+ 7x = 3x + 15 - x and 5(3x) + 7x = 3x + 10 - x .

Step-by-step explanation:

Hello!

The variable is

X: average mass of a sample of rocks collected in the waters of a region. (measured in grams)

Variables can be:

Quantitative: they represent number, any characteristic that can be "counted" is a quantitative variable, the most common examples are weight, volume, temperature, height, etc...

There are two types of quantitative variables:

⇒ Discrete variables: The only take certain values within the interval of definition of the variable, for example "number of sales" or "money in a wallet"

⇒ Continuous variables: They can take any value within an interval, in this example that you are working with mass, depending on the precision of the scale the mass can have infinite decimal values.

Qualitative: they represent characteristics that cannot be counted, meaning, they are not represented by numbers. There are many attributes that are qualitative variables, for example: colors, race of an animal, phenotypes, types of business, etc...

1)

The variable in this example is Quantitative, it takes numerical values, and the correct option is:

D. Quantitative, because numerical values, found by either measuring or counting, are used to describe the data.

2)

The values of mass of the rocks can take any value within the range of definition of the variable, they only depend on the precision of the scale used to weight the rocks.

B. Interval, because the differences in the data can be meaningfully measured, but the data do not have a true zero point.

3)

A standard 52-card deck contains 13 cards for each suit (clubs, diamonds, hearts and spades)

To calculate the probability of choosing a card at random and it being a Diamond, supposing that all cards are equally probable, you have to divide the total number of diamonds by the total number of cards in the deck:

P(diamond)= 13/52= 0.25

For items 4) and 5) the contingency tables are attached.

4)

a. and b. are conditional probabilities, to calculate them you have to apply the following formula: \(P(A|B)= \frac{P(AnB)}{P(B)}\)

This means that the probability of the event "A" given that event "B" has occurred is equal to the probability of the intersection between events "A" and "B" divided by the probability of event "B"

a. P(A|C)= \(\frac{P(AnC)}{P(C)}\)

To calculate the probability of the intersection P(A∩C) you have to divide the observations where both events cross by the total of observations on the table:

P(A∩C)= 10/50= 0.20

The probability of C is found in the margins of the table, in this case you have to divide the total of observations for event C by the total of observations of the table:

P(C)= 21/50= 0.42

Now you can calculate the asked probability:

\(P(A|C)= \frac{0.2}{0.42}= 0.48\)

b. P(C|A)= \(\frac{P(AnC)}{P(A)}\)

From item a. we already know that P(A∩C)= 10/50= 0.20

The probability of event A is  in the margin of the table and you calculate it as:

P(A)= 27/50= 0.54

Then:

\(P(C|A)= \frac{0.20}{0.54} = 0.37\)

c. P(BE)

This symbolized the probability of the events "B" and "E" occurring at the same time, you can also symbolize it as P(B∩E)

To calculate the probability of B and E happening you have to do as follows:

P(B∩E)= 8/50= 0.16

5)

a. P(C|A)= 0.37 (As calculated in 4b.)

b. P(BE) and c. P(EB) ⇒ Both expressions symbolize the intersection between events "B" and "E", P(B∩E)= P(E∩B)= 0.16 (As calculated in 4c.)

I hope this helps!

For (A ∪ C) - B: 30 + 25 - 7 - 3 = 45

For (B ∪ C) - A: 30 + 25 - 10 - 3 = 42

For A ∪ B ∪ C: 10 students pass at least one subject.

The existing details provide that among 10 students taking tests, groups A, B, and C have 30, 30, and 25 students respectively.

Additionally, scores overlap between pairings of the three groups - 11 students in groups A and B got a similar score, similarly, for students in groups B and C it was 10, while for those in groups A and C there were 7 who scored alike.

To indicate those passing all three exams, one can use the inclusion-exclusion principle and determine that 3 students did so.

Accounting for circumstances where individuals are themselves part of multiple categories,

(A ∪ C) - B gets us 45 and (B ∪ C) - A goes to 42.

On the whole, from A through C, no less than 10 test-takers ended up passing at least one exam.

In summary:

For (A ∪ C) - B: 30 + 25 - 7 - 3 = 45

For (B ∪ C) - A: 30 + 25 - 10 - 3 = 42

For A ∪ B ∪ C: 10 students pass at least one subject.

Missing information:

The question is incomplete and the complete question is shown in the attached picture.

After 2 hours, the second rescue worker finds the injured hiker and radios the first worker for help. The first worker arrives in approximately 28.5 minutes after jogging directly to the second worker at 6 mph.

We can start by finding the distances each worker covers in 2 hours.

For the first worker:

Distance = rate × time

Distance = 3.5 × 2 = 7 miles

For the second worker:

Distance = rate × time

Distance = 2.5 × 2 = 5 miles

Now we can use trigonometry to find the horizontal and vertical components of the first worker's displacement while walking:

Horizontal component = 7 × sin(25°) ≈ 3.01 miles

Vertical component = 7 × cos(25°) ≈ 6.30 miles

Similarly, we can find the horizontal and vertical components of the second worker's displacement:

Horizontal component = 5 × sin(54°) ≈ 4.07 miles

Vertical component = 5 × cos(54°) ≈ 3.62 miles

We can now find the horizontal and vertical components of the distance between the two workers:

Horizontal component = 3.01 - 4.07 ≈ -1.06 miles

Vertical component = 6.30 - 3.62 ≈ 2.68 miles

The distance between the two workers is the hypotenuse of a right triangle with these components as its legs:

Distance = √((-1.06)² + (2.68)²) ≈ 2.85 miles

Finally, we can find the time it takes for the first worker to cover this distance at 6 mi/h:

Time = Distance ÷ rate

Time = 2.85 ÷ 6 ≈ 0.475 hours or 28.5 minutes

Therefore, it will take the first worker about 28.5 minutes to arrive.

This is the final static variable for all instances.

That makes the behaviour much more obvious. Modern IDEs will usually suggest changing the second listing into the third.

There is no reason to have an inline declaration initializing the value like the following, as each instance will have its own NUMBER but always with the same value. This is the same than to have only one final static variable for all instances.

The static keyword means the value is the same for every instance of the class. The final keyword means once the variable is assigned a value it can never be changed. The combination of static final in Java is how to create a constant value.

The difference between the circumference of the circle and the perimeter of the triangle is 28.2 units. (Option B)

To find the length of each side of triangle, the distance is calculated between the vertices using the formula:

d = √((x2 – x1)^2 + (y2 – y1)^2)

Hence,

AB =√((-4 – 0)^2 + (9 – 0)^2) = 9.85 units

AC = √((9 – 0)^2 + (4 – 0)^2) = 9.85 units

BC = √((9 – (-4))^2 + (4 –9)^2) = 13.93 units

Hence, the perimeter of the triangle = 9.85 + 9.85 + 13.93 = 33.6 units

As AB and AC is the radius of the circle, the circumference of the circle is:

C = 2πr = 2π(9.85) = 61.8 units.

Hence, the difference between the circumference of the circle and the perimeter of the triangle = 61.8 – 33.6 = 28.2 units.
