4\(\sqrt{2}\)

Step-by-step explanation:

ratio of leg to hypotenuse in a 45-45-90° triangle is 1 : \(\sqrt{2}\)

we can use this proportion to solve the problem:

let 'x' = leg

x/8 = 1/\(\sqrt{2}\)

cross-multiply:

\(\sqrt{2}\) x = 8

x = 8 / \(\sqrt{2}\)

if you multiply top and bottom by \(\sqrt{2}\) you will get 4\(\sqrt{2}\)

The given table represents a discrete probability distribution.

To determine whether the table represents a discrete probability distribution, we need to check if it satisfies two conditions: the sum of probabilities equals 1 and all probabilities are non-negative.

In the given table, the sum of probabilities is 0.3 + 0.3 + 0.1 + 0.3 = 1, which satisfies the first condition.

Additionally, all probabilities in the table are non-negative, as each value of p(x) is greater than or equal to 0. This satisfies the second condition.

Therefore, since the table satisfies both conditions, it represents a discrete probability distribution. It provides the probabilities for each value of x, indicating the likelihood of each outcome occurring in a discrete random variable scenario.

The answer is False.

What is Probability ?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability was introduced in mathematics to predict how likely events are to occur.

The meaning of probability is basically the extent to which something is likely to happen. This is a basic theory of probability that is also used in probability distributions, where you learn the possibilities of outcomes for a random experiment.

To find the probability of a single event occurring, we should first know the total number of possible outcomes.

We can use the central limit theorem to approximate the distribution of the sample mean as normal, with a mean of μ = 70 and a standard deviation of σ/√n = 10/√4 = 5. Therefore, we need to find the probability of obtaining a sample mean greater than 65:

Z = (x - μ) / (σ/√n) = (65 - 70) / (5/2) = -2

Using a standard normal distribution table or calculator, we can find that the probability of obtaining a Z-score of -2 or less is approximately 0.0228.

Therefore, the probability of obtaining a sample mean greater than 65 is 1 - 0.0228 = 0.9772, which is not equal to 0.8413. So the statement is false.

There would be 17 lattice points lie on the hyperbola x²-y²=17

To find the lattice points on the hyperbola x²-y²=17, we can use some algebraic manipulation. First, we can rewrite the equation as y²=x²2-17, which means that both x² and y^2 must be integers.

Next, we can note that x² can only take on values that are congruent to 0 or 1 mod 4, since the only possible quadratic residues mod 4 are 0 and 1. This means that x must be an even integer or an odd integer that is ± 1 mod 4.

For each possible value of x, we can then solve for y by taking the square root of x²-17. However, we must be careful to only include the solutions where y is also an integer. This means that x²-17 must be a perfect square.

Using this method, we can check each possible value of x and find that the only lattice points on the hyperbola are (± 5, ± 2) and (± 4, ± 1). Therefore, there are a total of eight lattice points on the hyperbola x²-y²=17.

We are asked to find the F value that has a probability of 0.005 to its right, or a probability of 0.995 to its left. The answers are: E(F) = 1.3636, V(F) = 1.5097, and F0.005,11,15 = 2.91.

In statistics, an F distribution is a probability distribution that arises from the ratio of two independent chi-squared distributions. The F distribution is defined by two parameters, the numerator degrees of freedom and the denominator degrees of freedom.
In this case, we are given that the random variable F follows an F distribution with 11 numerator degrees of freedom and 15 denominator degrees of freedom. To find E(F) and V(F), we can use the following formulas:
E(F) = d2 / (d2 - 2), where d1 and d2 are the numerator and denominator degrees of freedom, respectively.
V(F) = [2d22(d1 + d2 - 2)] / (d12(d2 - 2)2(d2 - 4)), where d1 and d2 are the numerator and denominator degrees of freedom, respectively.
Substituting the given values, we have:
E(F) = 15 / (15 - 2) = 1.3636
V(F) = [2(15^2)(11 + 15 - 2)] / (11^2(15 - 2)^2(15 - 4)) = 1.5097
Finally, we are asked to find the F value that has a probability of 0.005 to its right, or a probability of 0.995 to its left. To do this, we can use a table or a calculator that provides F-distribution probabilities. For the given degrees of freedom, we find that F0.005,11,15 = 2.91.
Therefore, the answers are: E(F) = 1.3636, V(F) = 1.5097, and F0.005,11,15 = 2.91.

The mean of the binomial distribution with n = 40 and p = 3/5 is approximately 24.0.

A binomial distribution is a probability distribution that describes the number of successes in a fixed number of independent trials, where each trial has only two possible outcomes, commonly referred to as "success" and "failure."

The key parameters of a binomial distribution are:

n: the number of trials

p: the probability of success in each trial

q: the probability of failure in each trial (q = 1 - p)

The mean, or expected value, of a binomial distribution with parameters n and p is given by the formula:

E(X) = n * p

where X is a random variable that follows a binomial distribution.

Substituting n = 40 and p = 3/5 into the formula, we get:

E(X) = 40 * (3/5) = 24

Rounding to the nearest tenth, we get:

Michael needs to analyze the population data, demographics of the city, and the competition in the area to determine whether or not to open a new store.

Michael is trying to determine where to open two new store locations. He has population data to determine the amount of revenue he will receive for each location.

He is charged a $1000 fee for opening a new store at a certain location. However, he is unsure whether the population of the city would be large enough to warrant opening a new store at that location.

The first step that Michael needs to take is to analyze the population data that he has.

Based on the population data, he needs to make an informed decision about whether or not to open a new store at that location. This would require him to take into consideration the average income of the population as well as the demographics of the city.

Another important factor that Michael needs to take into consideration is the competition in the area. If there are already several stores in the area, then opening a new store might not be a good idea.

This is because the competition would be too high and he would not be able to generate enough revenue to make up for the cost of opening a new store.

However, if there are no stores in the area, then Michael might consider opening a new store. This would require him to invest a significant amount of money, but he could also generate a significant amount of revenue in return.

Additionally, he needs to take into consideration the cost of opening a new store and whether or not he can generate enough revenue to make up for that cost.

Overall, Michael needs to carefully analyze all the data that he has before making an informed decision about where to open new store locations.

In conclusion, Michael needs to analyze the population data, demographics of the city, and the competition in the area to determine whether or not to open a new store. If the population is large enough and there is no competition in the area, then he should consider opening a new store. However, if there is already a significant amount of competition in the area, then he should avoid opening a new store.

a. To calculate velocity, we need to take the derivative of the position function, r(t). So, the formula for velocity is v(t) = r'(t) = [sqrt(2)(e^t - e^-t) + sqrt(2)t(e^t + e^-t)]a.

b. To calculate acceleration, we need to take the second derivative of the position function, r(t). So, the formula for acceleration is a(t) = r''(t) = [sqrt(2)(e^t + e^-t) + sqrt(2)t(e^t - e^-t) + 2sqrt(2)t(e^t + e^-t)]a.

c. To calculate distance, we need to integrate the velocity function, v(t), over a certain time interval. So, the formula for distance is d(t1, t2) = ∫[t1, t2] v(t) dt = ∫[t1, t2] [sqrt(2)(e^t - e^-t) + sqrt(2)t(e^t + e^-t)]a dt.

d. To calculate position, we need to integrate the acceleration function, a(t), twice over a certain time interval. So, the formula for position is r(t1, t2) = ∫[t1, t2] ∫[t1, t] a(s) ds dt + r(t1), where r(t1) is the initial position at time t1.


a. Velocity (v) can be calculated using the derivative of the position function r(t). In this case, v(t) = dr(t)/dt.

b. Acceleration (a) can be calculated using the derivative of the velocity function v(t). So, a(t) = dv(t)/dt.

c. Distance (d) can be calculated by finding the definite integral of the velocity function v(t) with respect to time over a specific interval. In other words, d = ∫|v(t)|dt, where the integration limits correspond to the interval of time you're interested in.

If the saving rate is 1, it means that an individual or an economy saves their entire income and spends nothing. This implies that the consumption rate is 0, and all income is being saved.

In this scenario, the investment rate is equal to the saving rate, as there is no consumption spending. Therefore, the economy is investing all of its income in capital goods and not in consumption goods. This approach may result in high economic growth in the future due to the increased production capacity of the economy. However, in the short term, it may lead to a decrease in consumer demand and a decrease in output and employment in sectors producing consumer goods.

Hey there mate :)

When a number is multiplied by a fraction equal to 1, the value of the number remains the same.

Using this, we can find the values:-

Image 2 answers :

\( \frac{4}{5} \times \frac{4}{4} = \frac{4}{5} \)

When we cancel the same 4 of LHS remaining we get as 4/5. By doing the same method, we can find the remaining answers.

\(\frac{2}{3} \times \frac{7}{7} = \frac{2}{3} \\ \\ \frac{5}{6} \times \frac{8}{8} = \frac{5}{6} \\ \\ \frac{3}{4} \times \frac{5}{5} \)

Image 1 answers :

\( \frac{2}{3} \times \frac{4}{2} = \frac{4}{3}\)

Here, cancel the common numbers in LHS and write back the remaining uncancelled numbers to get 4/3 in RHS.

Using same method,

\( \frac{3}{4} \times \frac{5}{3} = \frac{5}{4} \)

Next, Now in last two questions, we have to do a little differently. Till this much time we did by cancelling the common numbers. So, multiply the numerator and denominator.

\( \frac{1}{4} \times \frac{3}{2} \\ = > \frac{1 \times 3}{4 \times 2} \\ = > \frac{3}{8} \)

So, above question's answer is 3/8.

Likewise, using the same method, find the next question :-

\( \frac{2}{5} \times \frac{4}{3} \\ = > \frac{2 \times 4}{5 \times 3} \\ = > \frac{8}{15}\)

So, next answer is 8/15.
