Given the following formula, solve for v.

8 = 1/2 a^2v + c

​

According to this equation, after 3.73 hours (3 hours, 44 minutes) of driving, Evin would run out of gas.

This equation, which is a mathematical statement showing that two or more mathematical expressions are equivalent or equal, shows the rate of change or consumption.

The rate of change that the equation demonstrates is computed as the unit of gas consumed per hour.

Gas Tank after 1 hour of driving = 7.25 gallons

Gas Tank after 4 hours of additional driving = 3.5 gallons

The quantity of gas consumed in 4 hours of driving = 3.75 gallons

The quantity of gas consumed per 1 hour of driving = 0.9375 gallons per hour (3.75/4).

The length of time that 3.5 gallons of gas can cover = 3.73 hours (3.5/0.9375)

= 3 hours 44 minutes.

Thus, Evin's car can only last for additional 3 hours 44 minutes, given the equation.

What is binomial distribution?

A popular probability distribution known as the binomial distribution simulates the likelihood of getting one of two outcomes given a set of parameters. It totals the number of trials when each trial has an equal chance of producing a particular result. By dividing the quantity of independent trials by the number of successes, one can calculate the value of a binomial.

Let X has binomial distribution with n = 15 and  p = 0.20

The PDF of the distribution can be written as:

P(X=x)  = nCx(p)x (1-p)n-x

Probability for 0 patients have broken bones can be calculated as:

P(x=0) = 15C0(0.20)0 (1-0.20)15-0

P(x=0)  = 0.035184 = 0.0352

Therefore, the probability is  0.0352

Complete Question

Suppose 20% of all emergency room patients have broken bones. of the next fifteen patients to arrive, what is the probability that none have broken bones?

Answer: 31.99$ or 32$

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 39.99 × 20/100

Discount = 39.99 x 0.2

You save = $8.00

Final Price = Original Price - Discount

Final Price = 39.99 - 7.998

Final Price = $31.99

Answer:

x/39.99 is the same as 20%/100% so you would cross multiply 39.99 x 20 then divide by 100 which is 16.8 then add 39.99 - 16.8 to get $23.19.

What is radioactive decay?

The process of radioactive decay is how an unstable atomic nucleus loses energy through radiation. A substance that has unstable nuclei is regarded as radioactive.

Here,

The half-life of the reaction is defined as the time required by a substance to reach half its initial concentration. It is represented by t(1/2)

 All radioactive decay processes follow the first-order reaction.

The equation for the half-life for first-order reaction follows:

t(1/2) = 0.693/k....(1)

where,

k = rate constant of a first-order reaction

Given value:

t(1/2) = 5715 years

Put the value of t in equation (1), and we get

k = 0.693/5715

k = 1.21×10⁻⁴yr

The integrated rate law expression for first-order reaction follows:

t = 2.303/k×㏒(a/(a-x))

where,

t = time period

a = initial concentration of the reactant = 58.2 counts per minute

(a-x) = Concentration of reactant left after time t = 38.0 counts per minute

k = rate constant of a first-order reaction

Put the values in the equation and we get

t = 2.303/1.21×10⁻⁴㏒58.2/38

t = 3523.77 years.

Hence, the age of the artifact is 3523.77 years.

Having a rectangular pasture for the animals to graze in is something a farmer wants in order to start growing cows, horses, goats, and sheep. She has decided to purchase 7500 ft of fencing. 1875 square feet is the maximum possible area that each of the four pens will enclose.

The maximum possible area of each pen is 1875 square feet. To calculate this, first calculate the total area of the large rectangle that the farmer is enclosing. To do this, multiply the total length of the fencing (7500 feet) by the width of the fence (1 foot). This gives us 7500 square feet as the area of the large rectangle.

Next, divide the area of the large rectangle by 4 to get the area of each pen. This gives us 1875 square feet as the maximum area of each pen.

Total Area of Large Rectangle = 7500 ft x 1 ft = 7500 sq ft

Area of Each Pen = 7500 sq ft / 4 = 1875 sq ft

For a test concerning a mean, a sample of size is obtained from a normal population. the population variance is known in testing versus the test statistic. Therefore, The Null Hypothesis is Rejected.

In mathematics, especially statistics, there are several kinds of instruments. Each average is used to summarize a particular group of data in order to better understand the overall values ​​(magnitude and sign) of a particular data set.

For datasets, the arithmetic mean, also called the "arithmetic mean", is a measure of the central tendency of a finite set of numbers. More specifically, the sum of the values ​​divided by the number of values. The arithmetic mean of a series of numbers x₁, x₂, ..., xₙ is usually given by the overhead bar. The dataset was based on a series of observations obtained by sampling from a statistical population. The arithmetic mean is the population mean.

Sample size is a term used in market research to define the number of subjects included in the sample size. Sample size means the group of subjects selected from the general population and considered representative of the actual population for this particular study.

For example, if you want to predict how a population of a certain age group will react to a new product, you can first test with a sample representative of your target group his size. In this case, the sample size is derived from the number of people interviewed in this age group.

Population variance is a measure of variance that determines how far each data point is from the population mean. Population variance can be defined as the average squared deviation from the mean of the data. Population refers to all observations within a finite group. Population variance is calculated based on the population. However, as the number of observations increases, some data points are selected that can represent the entire population. These specific data points form the sample, and the variance calculated from these data is called the sample variance. We can use the sample variance to estimate the population variance.

The probability that a person who tests positive actually has the disease is 0.1046.

This problem is a classic application of Bayes' law, but let's try a more concrete approach rather than a boilerplate approach.

Suppose 1,000,000 people are being tested.

According to the incidence, 0.5 percent should be ill, so we would expect 5,000 to be ill and 995,000 not to be ill.

We are testing 5000 of him for this disease. With only a 7% false negative rate, the test is pretty good. That is, out of 5,000 or 350 people with the disease, only 7% will test negative, and the remaining 4,650 will test positive.

We are testing 995,000 people who are not sick. With only a 4% false positive rate, the test is pretty good. That means only 4% of 995,000 or 39,800 diseased people will test positive. The remaining 955,200 will be negative.

4,650 sick and tested positive

39,800 not sick but tested positive

350 sick and tested negative

955,200 not sick but tested negative

our test 955,200 + 4,650 = 959,850 people tested

4,650 + 39,800 = 44,450 people tested positive, but only 4,650 actually tested positive. This is a very small percentage, only 465044450≈0.1046.

In other words, if your doctor says you tested positive, there's only about a 10.5% chance that you actually have the disease. That's the probability we're looking for, and this low value indicates that this test isn't very good.

2/ 62%

Step-by-step explanation:

Let's find the answer to the first question

Take 355 divided by 250, then times 100% = 142%

142% - 100% = 42% increase

So the percent increase is 42%

Now let's find the answer to the second question

First, find the total cost by 355 + 50 = $405

Take 405 divided by 250, then times 100% = 162%

162% - 100% = 62%

h = sqrt(2/3) * 6 inches

= sqrt(4/3) * sqrt(1/1) inches

= 2/sqrt(3) inches

How to determine the probabilities?

The required probabilities are conditional probabilities, and they are calculated using:

P(A | B) = P(A and B)/P(B)

Using the above formula, we have:

The probability that a customer eats snack A given that the customer has eaten snack A before, to be:

P = n(Have eaten snack A)/n(Snack A)

This gives

P = 144/252

Evaluate

P = 0.57

Also, we have:

The probability that a customer eats snack A given that the customer has not eaten snack A before, to be:

P = n(Have not eaten snack A)/n(Snack A)

Then:

x = -(-2)/ 2 × 1 = 1

Substitute this into the equation to obtain y:

y = 1² - 2 × 1  + 3 = 2

The point of the vertex is (1,2)  

The sign of a is positive, therefore, the parabola has a minimum.
