Answer:

C

Step-by-step explanation:

The nature of the solutions are determined by the value of the discriminant.

Given a quadratic equation in standard form ax² + bx + c = 0 : a ≠ 0

Then the discriminant is Δ = b² - 4ac

• If b² - 4ac > 0 then 2 real and distinct solutions

• If b² - 4ac = 0 then solutions are real and equal

• If b² - 4ac < 0 then solutions are not real, 2 complex conjugate solutions

Here b² - 4ac = - 6 , hence 2 complex conjugate solutions → C

Answer: C

Step-by-step explanation:

Answer:

B. 5.2%

Step-by-step explanation:

Total number of tables = 20

Number of tables next to window = 5

Number of tables next to salad bar = 5

Probability that the first customer chooses the window table = 5 out of 20 = [tex]\frac{5}{20}[/tex]

When this table is chosen, the total remaining tables are 19 out of which 4 tables are next to windows.

So, now the probability that a customer will choose a window table = 4 out of 19 = [tex]\frac{4}{19}[/tex]

Since the selection of two customers is independent of each other, the probability that two customers will chose the window table will be the product of probabilities of their individual selections.

Therefore, the probability that the next two customers will choose to sit at the window = [tex]\frac{5}{20} \times \frac{4}{19} = 0.052[/tex]

Thus, the probability that the next two customers will choose to sit at the window is 0.052 or 5.2%

Answer:

probability is 50 percent

Step-by-step explanation:

total area= 30000

area of secknd ring=15000

therefore 15000/30000 times 100

equals 50 percent

Answer:

Option D.

Step-by-step explanation:

From he given information, we get

Total area of a dartboard = 30,000 mm²

The area of the second ring = 15,000 mm²

We need to find the probability of landing in that second ring.

[tex]Probability=\dfrac{\text{The area of the second ring }}{\text{Total area of a dartboard}}[/tex]

[tex]Probability=\dfrac{15000}{30000}[/tex]

[tex]Probability=0.5[/tex]

Multiply the probability by 100 to find the percentage.

[tex]Probability=0.5\times 100[/tex]

[tex]Probability=50[/tex]

Hence the correct option is D.

Answer:

cos x cos (-x) -sin x sin (-x) = 1 ⇒ proved down

Step-by-step explanation:

* Lets revise the angles in the four quadrants

- If angle x is in the first quadrant, then the equivalent angles to it are

# 180 - x ⇒ second quadrant (sin (180 - x) = sin x , cos (180 - x) = -cos x

  tan (180 - x) = -tan x)

# 180 + x ⇒ third quadrant (sin (180 - x) = -sin x , cos (180 - x) = -cos x

  tan (180 - x) = tan x)

# 360 - x ⇒ fourth quadrant (sin (180 - x) = -sin x , cos (180 - x) = cos x

  tan (180 - x) = -tan x)

# -x ⇒fourth quadrant (sin (- x) = -sin x , cos (- x) = cos x

  tan (- x) = -tan x)

* Lets solve the problem

∵ L. H .S is ⇒ cos x cos (-x) - sin (x) sin (-x)

- From the rules above cos x = cos(-x)

∴ cos x cos (-x) = cos x cos x

∴ cos x cos (-x) = cos² x

- From the rule above sin (-x) = - sin x

∴ sin x sin (-x) = sin x [- sin x]

∴ sin x sin (-x) = - sin² x

∴ cos x cos (-x) - sin (x) sin (-x) = cos² x - (- sin² x)

∴ cos x cos (-x) - sin (x) sin (-x) = cos² x + sin² x

∵ cos² x + sin² x = 1

∴ R.H.S = 1

∴ L.H.S = R.H.S

∴ cos x cos (-x) -sin x sin (-x) = 1

Step-by-step explanation:

The empirical probability of a Great Pyrenees winning the 'Best of Show' at Amboy Kennel Club based on past performances is about 7.143%

The subject at hand is empirical probability, which is calculated by dividing the number of times an event has happened by the total number of outcomes. In this case, the event is a Great Pyrenees winning 'Best of Show' and the total number of outcomes is the total number of dog shows.

According to the data provided, the Great Pyrenees has won 3 times out of a total of 42 dog shows. Therefore, the empirical probability can be calculated as follows:

The empirical probability is then calculated by dividing the number of wins by Great Pyrenees by the total number of dog shows.

Therefore, the empirical probability of a Great Pyrenees winning is 3/42 = 0.07143. So, we could say that there is a 7.143% chance of a Great Pyrenees winning the 'Best of Show' in the future, based purely on historical data.

The empirical probability that the next "Best of Show" winner will be a Great Pyrenees is calculated to be 0.0714 or 7.14%.

Empirical probability is calculated based on observed data. In this case, we want to determine the probability that the next winner of "Best of Show" at the Amboy Kennel Club will be a Great Pyrenees.

Here's the breakdown:

The empirical probability (P) is calculated as:

P(Event) = Number of favorable outcomes / Total number of outcomes.

So, the empirical probability that the next winner will be a Great Pyrenees is:

P(Great Pyrenees) = 3 / 42 = 1 / 14 ≈ 0.0714.

Thus, the empirical probability is approximately 0.0714 or 7.14%.

Answer:

x = 4

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to solve for x

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

(x + 3)² + (4(x + 2))² = 25² ← expand parenthesis on left side

x² + 6x + 9 + 16(x+ 2)² = 625

x² + 6x + 9 + 16(x² + 4x + 4) = 625

x² + 6x + 9 + 16x² + 64x + 64 = 625 ← simplify left side

17x² + 70x + 73 = 625 ( subtract 625 from both sides )

17x² + 70x - 552 = 0 ← in standard form

with a = 17, b = 70, c = - 552

Using the quadratic formula to solve for x

x = ( - 70 ± [tex]\sqrt{70^2-(4(17)(-552)}[/tex] ) / 34

  = ( - 70 ± [tex]\sqrt{4900+37536}[/tex] ) / 34

  = - 70 ± [tex]\sqrt{42436}[/tex] ) / 34

  = - 70 ± 206 ) / 34

x = [tex]\frac{-70-206}{34}[/tex] = - 8.1176....

or x = [tex]\frac{-70+206}{34}[/tex] = 4

However, x > 0 ⇒ x = 4

Hence

x + 3 = 4 + 3 = 7 and

4(4 + 2) = 24

The triangle is a 7- 24- 25 right triangle

Answer:

81

Step-by-step explanation:

We know the number is between 50 and 100.  The prime factorization consists of only one prime number, so the number must be a perfect square.  The possible numbers are 64 and 81.

The rectangles that can be made with 64 tiles are:

1×64, 2×32, 4×16, 8×8, 16×4, 32×2, 64×1

The rectangles that can be made with 81 tiles are:

1×81, 3×27, 9×9, 27×3, 81×1

There are 7 rectangles that can be made with 64 tiles.  There are only 5 rectangles that can be made with 81 tiles.  Therefore, the mystery number is 81.

Step-by-step explanation:

The mystery number is 64, sqare number of 8 , the only prime number contributing to it being 2

Being x the mystery number

[tex]50 < x < 100[/tex]

The only two sqare numbers that meet this request are 64 and 81.

Not knowing much about the above mentioned rectangles, 81 being the perfect square number of a perfect square number we would consider 64 the only posible answer

Answer:

STV = 153 degrees

Step-by-step explanation:

180 - 18 = 162 (angles on a straight line equal 180 degrees)

3q + 15q = 162

18q = 162

q = 162 / 18

q = 9

STV = 15q + 18

       = 135 + 18

       = 153

Hope this helps!

UTV is a straight line, which equals 180 degrees.

This means both angles UTS and STV when added together must equal 180.

3q + 15q +18 = 180

Simplify:

18q +18 = 180

Subtract 18 from both sides:

18q = 162

Divide both sides by 18:

q = 162 / 18

q = 9

Now you have a value for q to solve the angle.

STV = 15q +18

Replace q with 9:

STV = 15(9) +18

Simplify:

STV = 135 + 18 = 153 degrees.

The given function [tex]f(x)=(2x+3)^2(3x+5)^2[/tex] is a polynomial function of degree 4, with a leading coefficient of 36 determined by multiplying the squares of the leading terms of the binomials.

The function[tex]f(x)=(2x+3)^2(3x+5)^2[/tex] is indeed polynomial. To determine the degree and the leading coefficient of a polynomial, we need to expand the given expression. However, without full expansion, we can deduce the degree by adding the exponents of the individual factors since the bases are polynomials of degree 1 (2x+3 and 3x+5).

Each factor is squared, so [tex](2x+3)^2[/tex] has degree 2 and ([tex]3x+5)^2[/tex]also has degree 2. By adding these, we find that the polynomial's degree is 2+2=4. To find the leading coefficient, we consider the leading terms of each binomial which are 2x and 3x. Squaring these and then multiplying them together [tex](2x)^2 * (3x)^2 = 4x^2 * 9x^2,[/tex]we get 36 as the leading coefficient when x is raised to the 4th power. Therefore, the correct answer is: This is a polynomial function of degree 4 with a leading coefficient of 36.

Answer:

a. 2 and 50

b. 10 and 10

Step-by-step explanation:

Let's denote the side lengths by x and y.

The area is 100 which means that x*y=100.

The only whole numbers which satisfy this are the following:

2,50

4,25

5,20

10,10

Just go through them one by one and find your answer.

The rectangle with an area of 100 square units and whole number side lengths with the largest perimeter is 50 by 2 with a perimeter of 104 units. The smallest perimeter rectangle possible for the same area is a square measuring 10 by 10, which has a perimeter of 40 units.

We are tasked with finding the dimensions of a rectangle with an area of 100 square units and whole number side lengths that will result in either the largest perimeter or the smallest perimeter.

Largest Perimeter Rectangle

To find the rectangle with the largest perimeter, we should aim for the rectangle to have the longest possible length and the shortest possible width while still maintaining an area of 100 square units. In the extreme case, this could be a rectangle with a length that approaches infinity and a width that is infinitely small, but we are limited to whole numbers. Therefore, the rectangle with the largest perimeter in this scenario would be 50 by 2, resulting in a perimeter of (50+2)*2 = 104 units.

Smallest Perimeter Rectangle

To find the rectangle with the smallest perimeter, we need to look for the most square-like dimensions, as a square has the smallest possible perimeter for a given area. For an area of 100 square units, the side lengths would be 10 by 10, so the perimeter would be 10*4 = 40 units.
