The percentage of his income he saved is 44.4%.

Percentage is a way of expressing a number as a fraction of 100. It is commonly used to represent a proportion or share of a whole, such as a percentage of a total amount, a percentage of a target or goal, a percentage of a population, etc.

In mathematical terms, a percentage can be represented as a decimal or a fraction, and is expressed as a symbol, such as "%".

If Ravindra's monthly income is rupee 90000 and saves rupee 40000 per month, then the percentage can be calculated as:

percentage = (40,000/90,000) x 100% = 44.4%

Hence, she saves 44.4% of his income per month.

The component of u along v is -17√2 / 5. To find the component of u along v, we can use the formula Component of u along v = (u · v) / |v| where u · v represents the dot product of u and v, and |v| represents the magnitude of v.

Given u = ⟨3, 0, 5⟩ and v = ⟨-3, 4, -5⟩, we can calculate their dot product:

u · v = (3 * -3) + (0 * 4) + (5 * -5) = -9 - 25 = -34

Next, we need to find the magnitude of v:

|v| = √((-3)^2 + 4^2 + (-5)^2) = √(9 + 16 + 25) = √50 = 5√2

Now, we can substitute these values into the formula to find the component of u along v:

Component of u along v = (-34) / (5√2)

To simplify, we can rationalize the denominator by multiplying both the numerator and denominator by √2:

Component of u along v = (-34√2) / (5√2 * √2)

                    = (-34√2) / (5 * 2)

                    = -17√2 / 5

Therefore, the component of u along v is -17√2 / 5.

Answer:

it's b

Step-by-step explanation:

it satifies Pythagoras theorem.

29² = 20²+21²

The measure of angle C is obtained as 35 degrees

Give that;

b^2 = a^2 + c^2 - 2ac Cos B

a = 29

c = 24

B = 101 degrees

b^2 = (29)^2 + (24)^2 - [2 * 29 * 24 cos 101]

b^2 = 841 + 576 + 266

b = 41 cm

Now;

b/sinB = c/sinC

bsinC = csinB

sinC = csinB/b

sinC =  24 * sin 101/41

C = sin-1(24 * sin 101/41)

The average time in minutes a customer spends waiting in line for service is  5.49 minutes, so the correct answer is D. none of the choices listed.

We can use Little's Law to find the average time a customer spends waiting in line for service:

Average time in line = (Average number of customers in line) / (Service rate)

To find the average number of customers in line, we can use the formula for the M/M/1 queuing system:

Lq = (ρ²) / (1 - ρ)

where

Lq is the average number of customers in the queue

ρ is the utilization of the server, which is equal to the arrival rate divided by the service rate

So, ρ = (Arrival rate) / (Service rate) = 28/35 = 0.8

And, Lq = (0.8^2) / (1 - 0.8) = 0.64 / 0.2 = 3.2

Now we can use Little's Law:

Average time in line = (Average number of customers in line) / (Service rate) = 3.2 / 35

Converting hours to minutes, we get:

Average time in line = (3.2 / 35) * 60 = 5.49 minutes

So the answer is D. none of the choices listed.

The standard deviation of the sampling distribution of the sample means is 20.8

What is Sample mean?

A sample is just a small part of a whole. For example, if you work for a polling company and want to know how much people pay for food a year, you aren’t going to want to poll over 300 million people. Instead, you take a fraction of that 300 million (perhaps a thousand people); that fraction is called a sample. The mean is another word for “average.” So in this example, the sample mean would be the average amount those thousand people pay for food a year.

The sample mean is useful because it allows you to estimate what the whole population is doing, without surveying everyone. Let’s say your sample mean for the food example was $2400 per year. The odds are, you would get a very similar figure if you surveyed all 300 million people. So the sample mean is a way of saving a lot of time and money.

Given that,

mean = \(\mu\) = 20.8

standard deviation =  σ   =  4.2

n=89

So, The sampling distribution of the sample means is:

\(\mu\bar x\) = \(\mu\)=20.8

Hence,

The standard deviation of the sampling distribution of the sample means is 20.8

The expected value of the product of two independent random variables X and Y is equal to the product of their individual expected values, given that the expected values of X and Y exist.

Let X and Y be two independent random variables. Then, the expected value of the product XY is given by:

E[XY] = ∫∫ xy fX(x) fY(y) dx dy

where fX(x) and fY(y) are the probability density functions of X and Y, respectively. Since X and Y are independent, their joint probability density function is given by:

fXY(x,y) = fX(x) fY(y)

Thus, the expected value of XY can be written as:

E[XY] = ∫∫ xy fX(x) fY(y) dx dy = ∫∫ xy fXY(x,y) dx dy

Now, we can use the linearity of expected value to split up the integral:

E[XY] = ∫∫ xy fXY(x,y) dx dy = ∫∫ x fX(x) y fY(y) dx dy

      = (∫ x fX(x) dx) (∫ y fY(y) dy) = E[X] E[Y]

Therefore, we have shown that E[XY] = E[X] E[Y], given that X and Y are independent and that the expected values of X and Y exist.

The function h(x, y) can be written as h(x, y) = (3x + 7y - 21)2 + (3x + 7y - 21). Another way to write it is as h(x, y) = h(x, y). The supplied functions f(x, y) = 3x + 7y - 21 and g(t) = t2 + t are combined into a single expression using this form.

In order to determine h(x, y), we need to insert the expression for f(x, y) into g(t). This will allow us to find h(x, y). Given that f(x, y) equals 3x + 7y - 21, we need to change g(t) to read as t = 3x + 7y - 21. Therefore, h(x, y) = g(f(x, y)) = g(3x + 7y - 21).

Now, by entering t = 3x + 7y - 21 into g(t), we get h(x, y) = (3x + 7y - 21)2 + (3x + 7y - 21), which is the answer we were looking for. This form illustrates the composition of the two functions f(x, y) and g(t) in order to derive h(x, y).

In the phrase that was arrived at as a result of this process, the term 3x + 7y - 21 is represented by its square, which is written as (3x + 7y - 21)2, while its square root is written as (3x + 7y - 21). When these two expressions are combined together, the result is h(x, y), which satisfies the equation h(x, y) = g(f(x, y)) = (3x + 7y - 21)2 + (3x + 7y - 21), which was given to us.

In the rescorla-wagner model, the symbol "λ" (lambda) refers to the limit of the amount of associative strength or learning that may occur.

What is Rescorla Wagner model?

Rescorla-Wagner model is a classical conditioning model which tries to establish a the relationship or association between the CONDITIONED STIMULI (CS) AND THE UNCONDITIONED STIMULI.

According to the Rescorla-Wagner model, proves that for learning to occur the subject must be surprised which means the subject must not expect it(AN UNEXPECTED US FOLLOWS A CS).

In the Rescorla-Wagner model, the symbol "V" (or sometimes referred to as "V_max") indicates the limit or maximum value of associative strength or learning that can occur between a conditioned stimulus (CS) and an unconditioned stimulus (US). This symbol represents the maximum strength or magnitude of association that can be formed during classical conditioning.

According to the Rescorla-Wagner model, learning occurs when there is a discrepancy or prediction error between expected and actual outcomes. As learning progresses, associative strength increases but eventually reaches a point of saturation or maximum value (V). This maximum value represents the point at which the association has reached its peak and further learning becomes unlikely or minimal.

Briefly, the “V” in the Rescorla-Wagner model represents an upper limit or ceiling on the amount of associative strength or learning that can be achieved between the CS and the US.

Answer:

If the relationship is proportional, we can use the proportionality constant, k, to relate the cost and number of climbs. The equation would be:

t = kc

We can find the value of k by using the given information that 5 climbs cost $52.50:

52.50 = k(5)

Solving for k, we get:

k = 10.50

Therefore, the equation that represents the total cost, t, of c climbs is:

t = 10.50c

The probability that more than 210 people will pass in front of his store is 0.2272.

In the question, we are given that a coffee shop owner wants to examine the number of customers who pass in front of his store in the morning from 7:00 A.M to 7:30 A.M.

We are asked to find the probability that more than 210 people will pass in front of his store if the mean number of customers during this time is 210.

This experiment follows a Poisson Distribution with a mean (λ) = 200, and the random variable X = 210.

To find the probability that more than 210 people will pass in front of his store, we will find P(X > 200).

P(X > 200) = 1 - P(X ≤ 210).

Now, P(X ≤ 210) can be calculated using the function poissoncdf(200,210) on the calculator.

As to find the probability of a Poisson Distribution P(X ≤ x), for a mean = λ, we use the calculator function poissoncdf(λ,x).

The value of poissoncdf(200,210) = 0.77271.

Thus, the value of P(X > 210) = 1 - 0.77271 = 0.22729.

Thus, the probability that more than 210 people will pass in front of his store is 0.2272.
