URGENT PLEASE HELP.

Answers

Answer 1
Let's call the cost of the video game system "x". Then the cost of the games would be 3x.

So the total cost would be x + 3x = 4x = $612.

Solving for x, we get:

x = $153.

Therefore, the cost of the video game system is $153 and the cost of the games is 3 * $153 = $459

E- No, because P(E∩H)=0.6

Answers

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.

What are mutually exclusive events?

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.

According to question:

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 SULT club has 4,000 members all age 25 with independent future lifetimes. The mortality for each member follows the Standard Ultimate LIfe Table. Calculate the largest N, using the normal approximation, such that the probability that there are at least N survivors at age 95 is at least 90%.

Answers

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.

4. How many distinct 6-digit numbers can be made using the digits 1, 1, 1, 2, 2, 3?
a. 108
b. 60
c. 220
d. 216
e.729

Answers

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.

4x - y = 3
3x + y = 4

Answers

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).

What is a Binomial Distribution?

The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.

The formula for Binomial Distribution is given by

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

where

n = number of trials

x = number of successes

p = probability of getting a success in one trial

q = probability of getting a failure in one trial

q = 1 - p

Given data ,

Let the number of trials n = 20

Let the probability of getting a 4 on the die be = 1/6

So , the value of p = 1/6

And , the probability of getting a failure q = 5/6

So , theoretical probability of rolling a 4 on this die = P ( x = 4 )

And , the Binomial Distribution is given by

P ( x = 6 ) = [ 20! / ( 20 - 6 )! 6! ] ( 1/6 )⁶ ( 5/6 )¹⁴

On simplifying the equation , we get

P ( x = 6 ) = [ 20 x 19 x 18 x 17 x 16 x 15 / 6 x 5 x 4 x 3 x 2 x 1 ) ( 1/6 )⁶ ( 5/6 )¹⁴

On further simplification , we get

P ( x = 6 ) = 0.0647

P ( x = 6 ) =  6.047 %

Hence , the probability of rolling a 4 is 0.0647

An account that compounds interest monthly has an annual percentage yield of 5.9%.

What is the annual interest rate for the account?

Answers

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%.

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.

Look for shared factors throughout the denominator and numerator. A fractional number can sometimes be checked to discover if it is a power of 2. A statement having two equal sides and an equal sign in the middle is referred to as a mathematical equation. Every variable's degree courses are listed in descending order as in general form of any equation. The formula for a linear equation is x + b = 0. The general form of a three separate linear equation is an x + b y + c = 0. (or something similar). Either conditioned equations or identities are categories for mathematics. An identity holds true for whatever value of the variables.

Troy set a goal for the total distance he wants to jog this week. He divided his goal evenly among the 5 jogs he planned for the week. Troy determined that each jog should be at least 2.8 miles to meet his goal.

Let x represent how many miles Troy wants to jog in all. Which inequality describes the problem?

Answers

The inequality describing the given problem is x/5 ≥ 2.8 and Troy should at least jog for 14 miles in total.

What is inequality?

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, Troy set a goal for the total distance he wants to jog this week. He divided his goal evenly among the 5 jogs he planned for the week. Troy determined that each jog should be at least 2.8 miles to meet his goal.

x represent how many miles Troy wants to jog in all. We need to find an inequality describes the problem.

Since, he has divided his goal into 5 jogs and in total he did x jogs, therefore, jog for 1 day = x/5

Now, he set that each jog should be at least 2.8 miles to meet his goal.

That mean, he can jog 2.8 miles or more than it but not less than it,

Therefore, inequality will be,

x/5 ≥ 2.8

Now, finding x,

Multiply both sides by 5,

x ≥ 14

Hence, the inequality describing the given problem is x/5 ≥ 2.8 and Troy should at least jog for 14 miles in total.

Let X be a continuous distribution with the density function f_X. Derive the random variable Y = | X-1 | density function f_Y. If X ~Unif (-1,0), what is the distribution of Y?

Answers

The density function of Y = | X-1 | is given by:

f_Y(y) = {f_X(y + 1), if 0 < y < 1;

        {f_X(1 - y), if 1 < y < 2;

        {0, otherwise.

Continuous distribution is a type of probability distribution that describes the likelihood of a variable taking on any value within a given range, rather than just specific values

If X ~Unif (-1,0), then the density function of Y is given by:

f_Y(y) = {1/2, if 0 < y < 1;

        {1/2, if 1 < y < 2;

        {0, otherwise.

Therefore, Y ~Unif (0,2).
