For this question, you could type it into the calculator.

Hence, this question is too trivial, and your question might get deleted as a result. Since this is your first question, I will help you out but subsequently, do use a calculator to solve this kind of questions.

Step-by-step explanation:

4 1/3 can be converted to 13/3 as an improper fraction.

Next, evaluate 13/3 divided by 5

(13/3) / 5 = (13/3) x (1/5)

               = 13/15

Answer:

Step-by-step explanation:

There are a number of ways to do this.  I am going to take a little longer, but I am hoping that it will make sense to you.

4\(\frac{1}{3}\) ÷ 5  

Another name for 1 is \(\frac{3}{3}\)  I am going to rewrite 4\(\frac{1}{3}\) knowing this.

\(\frac{3}{3}\) + \(\frac{3}{3}\) + \(\frac{3}{3}\) + \(\frac{3}{3}\) + \(\frac{1}{3}\) = \(\frac{13}{3}\)

Another way to write 5 is \(\frac{5}{1}\).

I want both of my fraction to have the same denominator so I will multiple

\(\frac{5}{1}\) x \(\frac{3}{3}\) = \(\frac{15}{3}\)  I am now ready to divide by fractions

\(\frac{13}{3}\) ÷ \(\frac{15}{3}\)  Divide across

\(\frac{\frac{13}{15} }{\frac{3}{3} }\) = \(\frac{\frac{13}{15} }{1}\) = \(\frac{13}{15}\)

Answer:

93,500,000

Step-by-step explanation:

Rounding rule:

1) If the digit directly next to the one you are finding is 5 or greater, round up.

2) If the digit is 4 or less, round down.

Note the hundred thousands place value (underlined and bolded):

93,487,991

Look at the digit value directly next to the place value you are looking for. The value of the digit is 8. Because 8 is greater then 5, round up:

93,487,991 rounded to the nearest hundred thousand is 93,500,000.

In parallelogram ABCD, ∠b = 55°; ∠d = 55. So, the correct answer is (a).

We know that opposite angles of a parallelogram are congruent. In another words, opposite angles of  parallelogram are equal. Therefore, we equate the angle B and angle D to each other and solve.

angle B = angle D

2n + 15 = 3n - 15

n = 30

The value of n is 30.

Now we can find the measures of angles B and D:

angle B = 2n + 15 = 2(30) + 15 = 75 degrees

angle D = 3n - 15 = 3(30) - 15 = 75 degrees

Therefore, the answer is (a) ∠b = 55°; ∠d = 55

Isotopes with long half-lives are not useful for dating fossils or rocks that span the last glacial-interglacial cycle (approximately between 12,000 and 125,000 years old) because their decay rates are too slow to provide accurate age determinations within that time range.

Isotopes with long half-lives, such as uranium-238 (with a half-life of about 4.5 billion years) and potassium-40 (with a half-life of about 1.3 billion years), are commonly used for dating much older geological events. These isotopes undergo radioactive decay at a slow rate, which makes them suitable for dating processes spanning millions or billions of years.

However, when it comes to dating fossils or rocks that fall within the last glacial-interglacial cycle (12,000 to 125,000 years old), the long half-lives of these isotopes pose a problem. The time scale of this cycle is relatively short compared to the decay rates of isotopes with long half-lives. As a result, the remaining isotopic ratios or concentrations after such a short time period may not provide precise age estimates, making them less reliable for dating within this specific range.

To obtain a 40% alcohol solution from a 22% solution, you need to add 18% more alcohol.

100 ml of 22% alcohol solution contains 22 ml of pure alcohol and 78 ml of other ingredients.

Therefore, to obtain a 40% solution, you need 40 ml of pure alcohol in every 100 ml of solution.

So, 18 ml of pure alcohol should be added to 100 ml of 22% solution to obtain 40% solution.

Another way to calculate this is:

You can calculate the amount of pure alcohol you need to add by multiplying the initial volume of the solution (100ml) by the percentage increase in alcohol content (18%) .

100ml * 18% = 18ml

So you would need to add 18ml of pure alcohol to 100ml of 22% alcohol solution to obtain a 40% alcohol solution.

Answer: i) 12.5%       ii) 87.5%        iii) 23.4%

Step-by-step explanation:

There are two die, each with 8 sides so the total number of outcomes is 8²

i) Product is a prime number --> 2, 3, 5, 7

Since it is a prime we only have the option of one die being a 1 and the other being the prime number.

So possible successful outcomes is: (1, 2), (1, 3), (1, 5), (1, 7), (7, 1), (5, 1), (3, 1), and (2, 1) = 8 options.

\(\dfrac{successful\ outcomes}{total\ possible\ outcomes}=\dfrac{8}{8^2}=\dfrac{1}{8}=\large\boxed{12.5\%}\)

ii) Not a perfect square.  Let's find the probability that it IS a perfect square and subtract that value from the total (64).

Product IS a perfect square --> 1, 4, 9, 16, 25, 36, 49, 64

Possible successful outcomes of a perfect square: (1, 1) (2, 2), (3, 3), (4, 4), (5, 5), (6, 6), (7, 7), (8, 8) = 8 options.

Product is NOT a perfect square = 64 - 8 = 56 options

\(\dfrac{successful\ outcomes}{total\ possible\ outcomes}=\dfrac{56}{8^2}=\dfrac{7}{8}=\large\boxed{87.5\%}\)

iii) Product is a multiple of 5 --> 5, 10, 15, 20, ,25, 30, 35, 40,

Possible successful outcomes of a multiple of 5: (1, 5), (2, 5), (3, 5), (4, 5), (5, 5), (6, 5), (7,5), (8, 5), (5, 8), (5, 7), (5, 6), (5, 4), (5, 3), (5, 2), (5, 1) = 15 options

\(\dfrac{successful\ outcomes}{total\ possible\ outcomes}=\dfrac{15}{8^2}=\dfrac{15}{64}=\large\boxed{23.4\%}\)

The probability is the ratio of the favorable event to the total number of events. The probability of a blue ball is 61.54 %.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

A bag contains 5 green marbles and 8 blue marbles.

Total number of balls will be

→ Total balls = 8 + 5 = 13

A dice is rolled, then a blue marble is chosen at random from the bag. Then the probability will be

→ Favorable event = 8

\(\rm P(B) = \dfrac{Favorable \ event}{Total \ event}\\\\P(B) = \dfrac{8}{13}\\\\P(B) = 0.6154 \ or \ 61.54 \ \%\)

Answer:

No, Noah used the diameter instead of the radius in the calculations.

V = 91.13π

Step-by-step explanation:

Noah is working on a geometry problem that involves finding the volume of a sphere with a diameter of 9 units. His work is shown below.

V = πr3

V = π(9)3

V = π(729)

V = 972π cubic units

Is Noah’s work correct

Volume of a sphere, V = πr³

radius, r = diameter / 2

Diameter = 9 units

r = 9 / 2

= 4.5 units

Volume of a sphere, V = πr³

= π × 4.5³

= π × 91.125

substitute the given values for x and do as the function says.

A.  The determinant of A is indeed the product of the eigenvalues of A.

B. The trace of A is equal to the sum of the eigenvalues of A.

PART A:

Let A be an n×n symmetric matrix that is orthogonally diagonalizable. This means that A can be written as A = PDP^T, where P is an orthogonal matrix and D is a diagonal matrix with the eigenvalues of A on its diagonal.

Since D is a diagonal matrix, the determinant of D is the product of its diagonal entries, which are the eigenvalues of A. So, we have det(D) = λ₁λ₂...λₙ.

Now, let's consider the determinant of A:

det(A) = det(PDP^T)

Using the fact that the determinant of a product is the product of the determinants, we can rewrite this as:

det(A) = det(P)det(D)det(P^T)

Since P is an orthogonal matrix, its determinant is ±1, so we have det(P) = ±1. Also, det(P^T) = det(P), so we can rewrite the above equation as:

det(A) = (±1)det(D)(±1)

The ± signs cancel out, and we are left with:

det(A) = det(D) = λ₁λ₂...λₙ

Therefore, the determinant of A is indeed the product of the eigenvalues of A.

PART B:

Similarly, let A be an n×n symmetric matrix that is orthogonally diagonalizable as A = PDP^T, where P is an orthogonal matrix and D is a diagonal matrix with the eigenvalues of A on its diagonal.

The trace of A is defined as the sum of its diagonal entries:

tr(A) = a₁₁ + a₂₂ + ... + aₙₙ

Using the diagonal representation of A, we can write:

tr(A) = (PDP^T)₁₁ + (PDP^T)₂₂ + ... + (PDP^T)ₙₙ

Since P is orthogonal, P^T = P^(-1), so we can rewrite this as:

tr(A) = (PDP^(-1))₁₁ + (PDP^(-1))₂₂ + ... + (PDP^(-1))ₙₙ

Using the properties of matrix multiplication, we can further simplify:

tr(A) = (PDP^(-1))₁₁ + (PDP^(-1))₂₂ + ... + (PDP^(-1))ₙₙ

= (P₁₁D₁₁P^(-1)₁₁) + (P₂₂D₂₂P^(-1)₂₂) + ... + (PₙₙDₙₙP^(-1)ₙₙ)

= D₁₁ + D₂₂ + ... + Dₙₙ

The diagonal matrix D has the eigenvalues of A on its diagonal, so we can rewrite the above equation as:

tr(A) = λ₁ + λ₂ + ... + λₙ

Therefore, the trace of A is equal to the sum of the eigenvalues of A.

For any prism, the base faces are parallel to one another, and they are congruent. In this case, the two triangles are the base faces.

The lateral sides are the three rectangles that form the "walls" so to speak. We can think of the base faces as the floor and ceiling.

The right-most wall is a 4 by 6 rectangle that has area 4*6 = 24 square km

The front-most wall is 8 by 4 leading to 8*4 = 32 square km area.

The back wall is a rectangle that is 10 by 4 to get an area of 10*4 = 40 square km.

The total lateral area is 24+32+40 = 96 square km

A shortcut is to compute the perimeter of the base to get 8+6+10 = 24 km, which multiplies with the height 4 to get 24*4 = 96 square km.

------------------------------

Now let's compute the area of one triangle

Each triangle has a base of 8 and a height of 6. So the area is

area = 0.5*base*height = 0.5*8*6 = 24 square km

There are two of these identical triangles, so we have a total base area of 24*2 = 48 square km

Add this onto the lateral area and we get the total surface area to be 48+96 = 144 square km

The z score that represents the 27th percentile in the standard normal distribution is -0.61.

The standard normal distribution has a mean of 0 and a standard deviation of 1. To find the z score that represents the 27th percentile, we need to find the value of z that corresponds to a cumulative probability of 0.27. Using a standard normal distribution table or calculator, we can find that the closest cumulative probability to 0.27 is 0.2660. The corresponding z score for this probability is -0.61.

To further explain, we can use the following steps to find the z score that represents the 27th percentile:
1. Identify the area to the left of the desired percentile: Since we want to find the z score that represents the 27th percentile, we need to find the area to the left of this percentile. This is simply the cumulative probability up to this point, which is 0.27.
2. Look up the z score for the area using a standard normal distribution table or calculator: Once we have the area, we can look up the corresponding z score using a standard normal distribution table or calculator. The closest cumulative probability to 0.27 is 0.2660, and the corresponding z score for this probability is -0.61.
Therefore, the z score that represents the 27th percentile in the standard normal distribution is -0.61.
