Write 8,360,000 in scientific notation

8,360,000

After one digit you should mark decimal then count after decimal how many digits are remaining after you get Ans then put your Ans always on 10.

Like this,

8.36× 100,000 = as 8.36 × 10⁶

Am mark decimal after one digit and count how many digits are remaining then am put my ans on 10

So, 8,360,000 written as 8.36 × 10⁶ in scientific notation

See this, there are two pairs one is 8.36 and one is 100,000 in first one we can't write zeros. We write numbers like 1,2,3,4,5,6,7,8,9 but not 0. Like this question is 8,360,000 , our first work is to mark decimal after one digit 8. then we have to notice that after decimal how many number are remaining like 360,000 As, we know we can't write zeros in first pair so we can write only 8.36× now our first pair is done , Second pair is so easy only you have to count digits after decimal 8360,000 So digits are 6 so our final answer is 8.36×10⁶

Always remember in second pair we write remaining no. of digits only on 10 like this 10⁶

8.36 × 10⁶

The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

Now, can you express 40,000,000,000 in the similar way ?

Count the number of zeros in it. It is 10.

So, 40,000,000,000 = 4.0×10¹⁰

Do you agree with the fact, that the number when written in scientific notation is much easier to read and understand.

The scientific notation of the given number is 8.36×10⁶.

Scientific notation is a method for expressing a given quantity as a number having significant digits necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power such as 1.56×10⁷.

The given number is 8,360,000.

In scientific notation

8,360,000 = 8.36×10⁶

Therefore, the scientific notation of the given number is 8.36×10⁶.

Answer:0.4375

Step-by-step explanation:

To solve the problem, we start by labeling 1/2 of 7/8 like this:

N1/D1 of N2/D2

Then we use this fraction of a fraction formula to solve the problem:

(N1 x N2) / (D1 x D2)

When we enter 1/2 of 7/8 into the formula, we get:

(1 x 7) / (2 x 8) = 7/16

Therefore, the answer to 1/2 of 7/8 in its lowest form is:

1/2 of 7/8 = 7/16

The quadratic equation x2 - 4x + 3 = 0 has two roots. The roots are given by the quadratic formula as x = [4 ± √(16 - 12)]/2, which gives x = [4 ± 2√3]/2. Therefore, the roots are x = 2 ± √3.
The quadratic equation x^2 - 4x - 3 = 0 has two roots.

To find the roots of this equation, we can use the quadratic formula:
x = (-b ± √(b^2 - 4ac))/(2a)

In this case, a = 1, b = -4, and c = -3. Plugging these values into the quadratic formula, we get:
x = (-(-4) ± √((-4)^2 - 4(1)(-3)))/(2(1))
x = (4 ± √(16 + 12))/2
x = (4 ± √28)/2
x = (4 ± 2√7)/2

Simplifying further, we get:
x = 2 ± √7

Therefore, the two roots of the equation are x = 2 + √7 and x = 2 - √7.

The answer to the given question is -4/3 or 1/2

The product of 6 and the square of a number is increased by 5 times the number, the result is 4.

Firstly, let's write the algebraic expression for the above statement and represent the number as x.

The algebraic expression can be written as:

(6 x x²) + 5x = 4

6x² + 5x = 4

The other expression can also be written as:

6x² + 5x - 4 = 0

Secondly, we must factorize the algebraic expression to solve for x.

6x² - 3x + 8x - 4 = 0

3x (2x - 1) + 4 (2x + 1) = 0

(3x + 4)(2x - 1) = 0

Thirdly, we need to solve for x.

3x + 4 = 0

3x = -4

Now, we need to divide both sides by 3.

3x/3 = -4/3

x = -4/3

or

2x - 1 = 0

2x = 1

Now, we need to divide both sides by 2.

2x/2 = 1/2

x = 1/2

Hence, the values that the number could be is -4/3 or 1/2.

due to the commutative law of multiplication the sequence of the operands of a multiplication does not matter.

a × b = b × a

this bases on the fact that a multiplication is nothing else than a special kind of addition

a × b = add a b times; or add b a times.

and as already the addition follows the commutative law

a + b = b + a

so, does then the multiplication.

The one of the inequalities is false, then the sides do not form a triangle.

Now, According to the question:

Side 1 of the triangle is = 4

Side 2 of the triangle is = 5

Side 3 of the triangle is = 10

Form a triangle :

To check if they form a triangle or not, we make use of triangle inequality theorem which states that; for sides a, b and c

a + b > c

a + c > b

b + c > a

So for sides 4, 5 and 10, we have:

4 + 5 > 10

4 + 10 > 5

5 + 10 > 4

Since the one of the inequalities is false, then the sides do not form a triangle.

Using the concept of conditional probability and the conditions provided, The answer is \(\frac {p^2}{2pq}\) .

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. Probabilities can be calculated using the ratio of the number of favorable outcomes to the total number of possible outcomes. It helps us to understand the uncertainty of events.

A false positive result is when a test indicates that a particular condition or attribute is present, when in reality it is not. For example, in medical testing, a false positive result would occur when a test for a disease returns a positive result but the person being tested does not actually have the disease. False positives can have serious consequences, as they can lead to unnecessary treatments, further testing, and anxiety for the person being tested.

p=probability of occurrence

q=1-p

P(false positive for both subjects | false positive for one subject) = P(false positive for both subjects and false positive for one subject) / P(false positive for one subject)

P(false positive for both subjects | false positive for one subject) = p^2 / (2pq)

Autocorrelation function of y(t) is Ry(τ) = E[y(t)y(t+τ)] = (1/2)Rx(τ)cos(w0τ) and power spectral density of y(t) is equal to Sy(w) = (1/2)Sₓ(w-w0) + (1/2)Sₓ(w+w0).

Autocorrelation function of y(t) is calculated E[y(t)y(t+τ)]

y(t)y(t+τ) = x(t)cos(w0t+q) x(t+τ)cos(w0(t+τ)+q)__(1)

We know,

cos(A +B) = cos(A)cos(B) - sin(A)sin(B)

Apply formula in(1) we get,

y(t)y(t+τ) = x(t)x(t+τ)cos(w0t+q)cos(w0τ) - x(t)x(t+τ)sin(w0t+q)sin(w0τ)

x(t) and q are independent.

Taking the expected value of both sides we get,

⇒E[y(t)y(t+τ)] = E[x(t)x(t+τ)]E[cos(w0t+q)cos(w0τ)] - E[x(t)x(t+τ)]E[sin(w0t+q)sin(w0τ)]

Expected value of cos(w0t+q)cos(w0τ) is equal to

E[cos(w0t+q)cos(w0τ)] = E[cos(w0t)cos(w0τ)cos(q) - sin(w0t)sin(w0τ)cos(q)] __(2)

As q is uniformly distributed over the range 0 < q < 2p

Expected value is equal to,

E[cos(q)]

=\(\int_{0}^{2\pi}\) cos(q) * 1/(2p) dq

= 0

Also, E[sin(q)] = 0

E[cos(q)sin(q)] = 0

Substitute in (2) we get,

E[cos(w0t+q)cos(w0τ)] = E[cos(w0t)cos(w0τ)] = (1/2)cos(w0τ)

Similarly,

E[sin(w0t+q)sin(w0τ)] = (1/2)cos(w0τ).

Substituting these values into the expression for E[y(t)y(t+τ)],

⇒E[y(t)y(t+τ)] = (1/2)Rx(τ)cos(w0τ)

Autocorrelation function of y(t) is equal  to,

Ry(τ) = E[y(t)y(t+τ)] = (1/2)Rx(τ)cos(w0τ)

Fourier transform of the autocorrelation function is the power spectral density .

Power spectral density of y(t),

Sy(w) = Fourier[Ry(τ)]

        = Fourier[(1/2)Rx(τ)cos(w0τ)]

Apply cos(A +B) = cos(A)cos(B) - sin(A)sin(B)

cos(w0τ) as the real part of exp(jw0τ).

Substituting this into Ry(τ),

Ry(τ) = (1/2)Rx(τ)Re[exp(jw0τ)]

Taking the Fourier transform of both sides,

Sy(w) = (1/2)Sₓ(w-w0) + (1/2)Sₓ(w+w0)

Therefore, autocorrelation function of y(t) is Ry(τ) = E[y(t)y(t+τ)] = (1/2)Rx(τ)cos(w0τ) and the power spectral density of y(t) is a sum of two shifted copies of the power spectral density of x(t), with peaks at w0 and -w0.

Step-by-step explanation:

Given the 2 equations

12x + 15y = 4140 → (1)

x + y = 300 ( subtract y from both sides )

x = 300 - y → (2)

Substitute x = 300 - y into (1)

12(300 - y) + 15y = 4140 ← distribute and simplify left side

3600 - 12y + 15y = 4140

3600 + 3y = 4140 ( subtract 3600 from both sides )

3y = 540 ( divide both sides by 3 )

y = 180

Substitute y = 180 into (2)

Given, Returns of the company for the last few years are 5%, 10%, -15%, 20%, -12%, 22%, 8%
Arithmetic Average return:
Arithmetic Average return = (sum of all returns) / (total number of returns)
Arithmetic Average return = (5 + 10 - 15 + 20 - 12 + 22 + 8) / 7= 18 / 7= 2.57
Therefore, the arithmetic average return of the company is 2.57%.
Geometric average return:
Geometric average return = [(1+R1) * (1+R2) * (1+R3) * …….. * (1+Rn)]1/n - 1
Geometric average return = [(1.05) * (1.1) * (0.85) * (1.2) * (0.88) * (1.22) * (1.08)]1/7 - 1= 0.13
Therefore, the geometric average return of the company is 13%.
Variance:
Variance = (sum of (return - mean return)2) / (total number of returns)
Mean return = (5 + 10 - 15 + 20 - 12 + 22 + 8) / 7= 18 / 7= 2.57
Variance = [(5-2.57)2 + (10-2.57)2 + (-15-2.57)2 + (20-2.57)2 + (-12-2.57)2 + (22-2.57)2 + (8-2.57)2] / 7= 392.12 / 7= 56
Therefore, the variance of the company is 56.
Standard Deviation:
Standard Deviation = Square root of Variance
Standard Deviation = √56= 7.48
Therefore, the standard deviation of the company is 7.48%.

Thus, Arithmetic average return of the company is 2.57%.Geometric average return of the company is 13%.Variance of the company is 56.Standard deviation of the company is 7.48%.
