What is the Reciprocal of 1/10

By applying binomial distribution formula, it can be concluded that the probability less than two have a side effect is 56.86%.

Binomial distribution is the discrete probability distribution of the number of successes or failures in n independent trials, where each trial result has a probability p.

P(x) = C(n,x) · pˣ · qⁿ⁻ˣ where:

C = number of combinations

p = probability of success

q = probability of failure

x = number of times for a specific outcome within n trials

n = number of trials

We have the following information:

p = 12% = 0.12, thus:

q = 1 - p

  = 1 - 0.12

  = 0.88

n = 12

We want to find the probability less than two have the side effect, P(x<2):

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

          = (C(12,0) · 0.12⁰ · 0.88¹²)  +   (C(12,1) · 0.12¹ · 0.88¹¹)

          = (1 · 1 · 0.2157)   +   (12 · 0.12 · 0.2451)

          = 0.2157 + 0.3529

          = 0.5686 ≈ 56.86%

Thus, the probability less than two have the side effect is 56.86%.

The distance between the points A and B is 209.4 feet

An equation is an expression that contains numbers and variables linked together by mathematical operations of addition, subtraction, multiplication, division and exponents. An equation can either  be linear, quadratic, cubic, depending of the degree of the variable.

Trigonometric ratio is used to show the relationship between the sides and angles of a right triangle.

A boat is heading towards a lighthouse, whose beacon-light is 107 feet above the water. From point A, the boat’s crew measures the angle of elevation to the beacon, 12°. Let a represent distance from point A to light house:

tan(12) = 107/a

a = 503.4 feet

They measure the angle of elevation a second time from point B at some later time to be 20°. Hence, if b represent distance from point A to light house:

tan(20) = 107/b

b = 294 feet

Distance from point A to B = 503.4 feet - 294 feet = 209.4

The distance between the points is 209.4 feet

To determine if the triangle is a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

Let's label the sides of the triangle as follows:

a = 4 inches

b = 5 inches

c = 7 inches

Using the Pythagorean theorem, we can calculate:

c^2 = a^2 + b^2

7^2 = 4^2 + 5^2

49 = 16 + 25

49 = 41

Since 49 does not equal 41, this means that the triangle is not a right triangle.

Therefore, the answer is no, the triangle is not a right triangle.

The measures of the angles X, Y, and Z are 5, 50, and 125 degrees.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Given that in ∆XYZ, the measures of angles X, Y, and Z, respectively, are in the ratio 1:10:25.

We have to find the measure of each angle.

Let the measures can be expressed as 1x, 10x, and 25x, respectively, where x is an arbitrary value.

We know that the sum of the angles of a triangle is always 180 degrees, so:

1x + 10x + 25x = 180

36x = 180

Divide both sides by 36

x = 5

Therefore, the measures of the angles X, Y, and Z are 5, 50, and 125 degrees.

If a back-to-school sale offered a laptop for $379 and this sale price reflected a 15% discount, after using the equation the cost of the computer before the reduction in price is, $446.47.

Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".

Let's call the original cost of the laptop "x".

The equation to find the cost after a discount is:

x - x * (discount rate) = sale price

In this case, the discount rate is 15%, or 0.15. Plugging in the given values:

x - x * 0.15 = 379

Expanding the equation:

x - 0.15x = 379

0.85x = 379

Dividing both sides by 0.85:

x = 379 / 0.85

x = 446.47

So, the cost of the laptop before the reduction in price was $446.47.

Answer:

a. To find the annual net income, subtract the annual expenses from the annual rental income.

The annual rental income = $750 * 12 months = $9,000

So, the annual net income = $9,000 - $6,890 = $2,110

b. To find the annual yield, divide the annual net income by the investment cost (the down payment) and multiply by 100 to get the answer as a percentage.

The annual yield = ($2,110 / $28,500) * 100 = 7.41%

c. To find the monthly rent required to get a yield of 90%, divide the investment cost by the desired yield and divide by 12 to get the monthly rent.

The investment cost = $28,500

The desired yield = 0.90

So, the monthly rent = ($28,500 / 0.90) / 12 = $2,306.25

a. The total of the two sides of the right triangle using Algebraic expression is 3x²+7x-4.

b. The length of the missing side of the triangle is 3x³-4x²-15x+5.

c. If the value of x=2, then the length of the three sides of the triangle is

   a=11, b=11 and c= -17.

d. No, it is not possible to have these side lengths for a right triangle.

Algebra is a discipline of mathematics that studies symbols and the mathematical operations that can be applied to them. These symbols are referred to as variables because they don't have predetermined values. These values are usually represented in algebra by variables, which are symbols like x, y, z, p, or q. These symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations in order to ascertain the values.

a. Let the sides of the right triangle be a, b and c.

Given, one side of the triangle is 2x² + 2x - 1 and

another side is 5x + x² -3.

So, let a = 2x²+2x-1 and b = 5x+x²-3

Now, the total of the two sides= a+b

          a+b

         =2x²+2x-1 + 5x+x²-3

         = 3x²+7x-4

Therefore, the total of the two sides of the right triangle = 3x²+7x-4.

b. Now the perimeter of the triangle is given= 3x³-x²-8x+1.

Given, a+b+c=3x³-x²-8x+1.

We already have a+b, so by simplifying the equation a+b+c=3x³-x²-8x+1

we can find the length of the third side, c.

a+b+c= 3x³-x²-8x+1

⇒3x²+7x-4 +c= 3x³-x²-8x+1

⇒c= 3x³-x²-3x²-8x-7x+1+4

⇒c= 3x³-4x²-15x+5.

Therefore, length of the missing side is 3x³-4x²-15x+5.

c. We have the three sides of the triangle with us which are:

a = 2x²+2x-1

b = 5x+x²-3

c = 3x³-4x²-15x+5

Now putting the value of x as 2 in the equations as follows:

a= 2(2²) +2(2)-1

 = 8+4-1

 =11

b=5(2) +2²-3

 = 10+4-3

 =11

c=3(2³)- 4(2²) -15(2) +5

 =24-16-30+5

 = -17

Therefore, the length of the three sides of the right triangle

are 11, 11 and -17.

d. The sides of the right triangle are.

a = 11

b = 11

c = -17

We know as per the Pythagorean theorem c² = a² + b².

Accordingly, c²= 289 & a² = 121 and b²= 121, a² + b²= 242

which shows that c² is not equal to a² + b².

As, the sides of the triangle does not follow the Pythagorean theorem, so these are not the sides of a right-angle triangle.

[tex]P(n,r)=\dfrac{n!}{(n-r)!}[/tex]

where:

Given P(3, 2):

So we need to calculate the permutations of two numbers taken from three numbers.

The numbers are 1, 2 and 3.  As order matters, the number of ways two numbers from this set can be arranged is:

Therefore, there are 6 ways two numbers from the set of three numbers can be arranged.

To prove this, substitute n = 3 and r = 2 into the permutation formula:

[tex]\begin{aligned}\implies P(3,2)&=\dfrac{3!}{(3-2)!}\\\\&=\dfrac{3!}{1!}\\\\&=\dfrac{3 \times 2 \times 1}{1}\\\\&=\dfrac{6}{1}\\\\&=6 \end{aligned}[/tex]

The length of the hypotenuse of the isosceles right triangle is 2.8 inches.

An isosceles right triangle is a right triangle with two equal sides. In this case, the two equal sides are each 7 8 inches long.

To find the length of the hypotenuse, we can use the Pythagorean theorem:

a^2 + b^2 = c^2, where c is the length of the hypotenuse

In this case, a = b = 7/8 inches, so:

(7/8)^2 + (7/8)^2 = c^2

(49/64) + (49/64) = c^2

98/64 = c^2

c = sqrt(98/64) inches

To the nearest tenth, c = 2.8 inches, so the length of the hypotenuse of the isosceles right triangle is 2.8 inches.

⇒ y = -2( x - 15 )² + 200

This equation is in the form of y =  a(x - h)² + k where the vertex of the parabola is (h , k).

Therefore the vertex of the parabola is at (15 , 200)

Hence, we can conclude that Sofie will maximum profit of $200 if she sells a scarf at 15$ and will make the least profit if she sells the scarf at $5 or less.
