Which of the below are equations of exponential graphs?

The value of 2:3 can be written as a fraction: 2/3.

What is the ratio?

In mathematics, a ratio is a comparison of two quantities, often expressed as a fraction or using the colon (:) symbol. Ratios are used to indicate the relative size or amount of two or more things.

For example, the ratio of the length of a rectangle to its width can be expressed as a fraction, where the numerator represents the length and the denominator represents the width.

The ratio of hydrogen atoms to nitrogen atoms is 2:3.

This means that for every 2 hydrogen atoms, there are 3 nitrogen atoms in the container. The value of the ratio 2:3 is a way of expressing the relative quantity of hydrogen atoms to nitrogen atoms in a simplified form. It can also be written as a fraction: 2/3.

Hence, the value of 2:3 can be written as a fraction: 2/3.

Step-by-step explanation:

The largest N such that the probability that there are at least N survivors at age 95 is at least 90% is approximately 136.43.

The normal approximation can be used to estimate the number of survivors at a given age when the mortality follows the Standard Ultimate Life Table. The normal approximation assumes that the number of survivors follows a normal distribution.

Let X be the number of survivors at age 95. Then, the mean (μ) and standard deviation (σ) of X can be calculated using the following formula:

μ = 4,000 * e⁽⁻⁰.⁰⁷³⁶⁽⁹⁵⁻²⁵⁾⁾

σ = √(4,000 * (1 - e⁽⁻⁰.⁰⁷³⁶⁽⁹⁵⁻²⁵⁾⁾) * e⁽⁻⁰.⁰⁷³⁶⁽⁹⁵⁻²⁵⁾⁾)

Next, we can find the value of N such that P(X >= N) >= 0.9 using the standard normal distribution.

z = (N - μ) / σ

P(X >= N) = 1 - P(X < N) = 1 - Φ(z)

where Φ(z) is the cumulative distribution function of the standard normal distribution.

We want to find the largest N such that P(X >= N) >= 0.9, so we need to find the smallest z such that Φ(z) <= 0.1. The value of z can be found using a standard normal table or a calculator with normal distribution functions.

With a calculator, we get that z = 1.28. So, N = μ + z * σ.

Plugging in the values we calculated earlier, we get:

N = 4,000 * e⁽⁻⁰.⁰⁷³⁶⁽⁹⁵⁻²⁵⁾⁾ + 1.28 * √(4,000 * (1 - e⁽⁻⁰.⁰⁷³⁶⁽⁹⁵⁻²⁵⁾⁾) * e⁽⁻⁰.⁰⁷³⁶⁽⁹⁵⁻²⁵⁾⁾)

N = 4,000 * e⁽⁻⁰.⁰⁷³⁶⁽⁷⁰⁾⁾ + 1.28 * √(4,000 * (1 - e^⁽⁻⁰.⁰⁷³⁶⁽⁷⁰⁾) * e^⁽⁻⁰.⁰⁷³⁶⁽⁷⁰⁾⁾

N = 4,000 * 0.0337 + 1.28 * √(4,000 * (1 - 0.0337) * 0.0337)

N = 132.8 + 1.28 * √(4,000 * 0.966 * 0.0337)

N = 132.8 + 1.28 * √(13.97376)

N = 132.8 + 3.63323

N ≈ 136.43

So, the largest N such that the probability that there are at least N survivors at age 95 is at least 90% is approximately 136.43.

Answer:

B. 60

Step-by-step explanation:

Since the digits 1, 1, 1, 2, 2, 3 are repeated, we use the concept of permutations with repetition. In this case, we can choose the first digit to be any one of the three, the second digit to be any one of the three, and so on. Therefore, the total number of distinct 6-digit numbers that can be made is 3 × 3 × 3 × 3 × 3 × 3 = 729.

However, we need to exclude the numbers that start with a 0 (i.e., numbers like 011112 or 001122). Therefore, the final answer is 729 - 3 = 726, which is the number of 6-digit numbers that do not start with a 0. The number of 6-digit numbers that start with a 0 is 3 (111120, 111202, 112102), so the total number of distinct 6-digit numbers is 726 - 3 = 60.

The required events E and H are not mutually exclusive, because they can both occur at the same time.So  D - No, because P(E∩H) = 0.20 is correct.

The events E and H are not mutually exclusive, because they can both occur at the same time. In other words, a student can have both brown eyes and brown hair.

The probability that a student has both brown eyes and brown hair, P(E∩H), can be found using the formula:

P(E∩H) = P(E) + P(H) - P(E or H)

where P(E) is the probability of having brown eyes, P(H) is the probability of having brown hair, and P(E or H) is the probability of having either brown eyes or brown hair.

Given that:

P(E) = 0.35

P(H) = 0.45

P(E or H) = 0.60

So,

P(E∩H) = 0.35 + 0.45 - 0.60 = 0.20

So, the answer is D - No, because P(E∩H) = 0.20.

The value of x in the given paralellogram is 12.

What is parallelogram?

"It is a quadrilateral with parallel opposite sides."

"The opposite angles of parallelogram are equal. "

For given question,

Two of the angles in a parallelogram measure 8x° and 7x°

The measure of an angle opposite to 8x° is also 8x°

In a similar manner, an angle opposite to 7x° is measured as 7x°.

So, we have the four angles of parallelogram as 8x°, 7x°, 8x°, 7x°

We are know that the total angle of a quadrilateral is 360°.

⇒ 8x° + 7x° + 8x° + 7x° = 360°

⇒ (5 + 7 + 5 + 7) x = 360

⇒ 30x = 360

⇒ x = 12

Therefore, the value of x is 15.

Answer: (x, y) = (5/4, 2).

The given system of equations is:

4x - y = 3

3x + y = 4

We can solve for x and y using either substitution or elimination method.

By substitution, we can solve for y in one of the equations and substitute that value into the other equation to solve for x.

Starting with 4x - y = 3, we can add y to both sides to isolate x:

4x = 3 + y

Then, we can substitute this expression for y into the second equation:

3x + (3 + y) = 4

Expanding the right side, we get:

3x + 3 + y = 4

3x + 3 = 4 - y

3x = 1 - y

x = (1 - y)/3

Now, we can substitute the expression for x into the first equation:

4((1 - y)/3) - y = 3

4(1 - y)/3 = 3 + y

4 - 4y/3 = 3 + y

1 - 4y/3 = y + 3

-3y/3 = -2

y = 2

Finally, we can substitute the value of y into one of the original equations to find x:

4x - 2 = 3

4x = 5

x = 5/4

So, the solution to the system of equations is (x, y) = (5/4, 2).

Answer: The annual percentage yield (APY) is the total amount of interest earned on an investment over a year, expressed as a percentage of the initial investment. The annual interest rate is simply the interest rate per year, expressed as a percentage.

To convert the APY to the annual interest rate, we can divide the APY by the number of times the interest is compounded in a year. If the interest is compounded monthly, then the number of times the interest is compounded in a year is 12.

So, the annual interest rate for the account is given by:

Annual interest rate = APY / number of times compounded in a year

= 5.9% / 12

= 0.49%

Therefore, the annual interest rate for the account is 0.49%.

If we subtract 14 from both sides of the equation for RU, we get 6p = RU - 14, or 6p = RU - 14. We can then substitute this expression for 6p into the equation for ST to get:

ST = p + 31

ST = (RU - 14) + 31

Expanding RU, we get:

ST = RU - 14 + 31

ST = RU + 17

Since RU = 6p + 14, we can substitute this expression into the above equation to solve for p:

ST = 6p + 14 + 17

ST = 6p + 31

Finally, we can subtract 31 from both sides of the equation to find p:

ST - 31 = 6p + 31 - 31

ST - 31 = 6p

ST - 31 = 6p

p = (ST - 31) / 6

So, to find the value of p, we need to know the value of ST.
