(-1/4)x + 2 = 8

Multiply all terms by 4.

(-1)x + 8 = 32

Simplify.

-x + 8 = 32

Subtract 8 from both sides.

-x = 24

Multiply both sides by -1.

x = -24.

The value of x is equal to -24.

-1/4(-24) + 2 = 8


Final answer:

Evaluating functions is the process of substituting a specific value in place of the variable in a function to compute a result. For example, given the function f(x) = x^2, if asked to find f(2), you would replace x with 2 resulting in 4.

Explanation:

Evaluating functions in mathematics involves inserting a specific numerical value or a variable into a function to compute a result. For example, if you're given the function f(x) = x^2, and you're asked to find f(2), you simply substitute 2 in place of x in the function, resulting in 2^2, which equals 4.

For instance, if we were to evaluate f(5) for the given function, it would give the result 25 because 5^2 = 25. Hence, simply put, to evaluate a function is to replace the variable with the input value, and compute the result.

A​ town's population is 53,075. About 100 people move out of the town each month. Each​ month, 200 people on average move into town. A nearby town has a population of 55,825. It has no one moving in and an average of 175 people moving away every month. In about how many months will the populations of the towns be​ equal? Write an equation to model the situation. Then solve the equation and answer the question.

Answers

Answer:53075 -100m +200m = 55825 -175mm = 10; the populations will be equal in 10 monthsStep-by-step explanation:

If we let m represent the number of months, then the population increase of the first town is 100m and its decrease is 200m. The population decrease of the second town is 175 m.

We want to find m such that the increases and decreases make the towns' populations equal. We add the increases and subtract the decreases to the base population in each case.

... first town population = second town population

Use the calculator provided and round your answer to the nearest dollar.

Answers

After 5 years, the resale value of the laptop will be approximately $592.

The resale value of the laptop after each year can be calculated by multiplying the previous year's value by 0.75. Starting with the initial value of $2500, the resale value after 5 years can be found by multiplying $2500 by 0.75 five times. Let's calculate:

Year 1: $2500 x 0.75 = $1875Year 2: $1875 x 0.75 = $1406.25Year 3: $1406.25 x 0.75 = $1054.69Year 4: $1054.69 x 0.75 = $790.02Year 5: $790.02 x 0.75 ≈ $592.52

Pvc pipe is manufactured with a mean diameter of 1.01 inch and a standard deviation of 0.003 inch. the diameters are known to be normally distributed. find the probability that a random sample of n = 9 sections of pipe will have a sample mean diameter greater than 1.009 inch and less than 1.012 inch.

Answers

Answer:

about 82%

Step-by-step explanation:

The distribution of sample means has a standard deviation that is the pipe standard deviation divided by the square root of the sample size. Thus, the standard deviation of the sample mean is 0.003/√9 = 0.001.

Then the limits on sample mean are 1.010 - 1×0.001 = 1.009 and 1.010 +2×0.001 = 1.012. The proportion of the normal distribution that lies between -1 and +2 standard deviations is about 81.9%.

Final answer:

The problem involves statistical calculation involving mean, standard deviation, and Z-scores of a normal distribution. We first calculate sample standard deviation, then the Z-scores for the given range. After finding probabilities for the Z-scores, we subtract to get the final probability of 0.8185.

Explanation:

The problem at hand involves the field of statistics, specifically, the normal distribution, sample mean, and standard deviation. We can use the following steps to solve the problem:

Determine the standard deviation of the sample. Given the standard deviation of the population (σ population) is 0.003 inch and the sample size (n) is 9, we use the formula σ sample = σ population/sqrt(n), which gives 0.003/sqrt(9) = 0.001.Calculate the Z-scores for 1.009 and 1.012. The Z-score is determined by the formula: Z = (X - μ) / σ. For X=1.009, Z1 = (1.009-1.01)/0.001 = -1. For X=1.012, Z2 = (1.012-1.01)/0.001 = 2.Using a Z-table or appropriate statistical software, find the probability corresponding to these Z-scores. The probability for Z1=-1 is 0.1587, and for Z2=2, it is 0.9772.Lastly, subtract the smaller probability from the larger one to get the probability that a sample mean is greater than 1.009 but less than 1.012. So, the answer is 0.9772 - 0.1587 = 0.8185.

Given that tan 0=-1, what is the value of sec0 for 3pi/202pi?

Answers

Answer:

   = -sqrt(2)

Step-by-step explanation:

tan theta = -1

we know tan = opposite/ adjacent

So opposite/adjacent = -1

Multiply by adjacent on each side

opposite = - adjacent

We also know from pythagorean theorem that

opposite ^2 + adjacent ^2 = hypotenuse ^2

Substituting in for adjacent

opposite ^2 + (-opposite ) ^2 = hypotenuse ^2

opposite ^2 + opposite ^2 = hypotenuse ^2

2 opposite ^2 = hypotenuse ^2

 Taking the square root on each side

sqrt(2 opposite ^2)   =  sqrt(hypotenuse ^2)

sqrt(2) opposite = hypotenuse


We are now set to find the sec

sec theta = hypotenuse / adjacent

               = sqrt(2) opposite/ adjacent

Replace the opposite = -adjacent

                 = sqrt(2) (-adjacent)/adjacent)

                 = -sqrt(2)

The value of secθ for 3π/ 2 < θ< 2π is √2. This is because tanθ is negative in Quadrant III and sec²θ = 1 + tan²θ. Therefore, secθ = √2.

Step 1: Determine the quadrant of θ

We know that 3π/ 2 < θ< 2π, which means that θ is in Quadrant III. In Quadrant III, tanθ is negative and secθ is positive.

Step 2: Use the identity sec²θ = 1 + tan²θ to solve for secθ

The identity sec²θ = 1 + tan²θ can be used to solve for secθ given tanθ. Substituting tanθ = -1 into the identity, we get:

sec²θ = 1 + (-1)² = 2

Taking the square root of both sides, we get:

secθ = √2

Therefore, the value of secθ for 3π/ 2 < θ< 2π is √2.

The sum of the measures of the angles of the triangle is equal to 180 °.

Therefore we have the equation:

[tex]y+(y-12)+56=180[/tex]         combine like terms

[tex]2y+44=180[/tex]              subtract 44 from both sides

[tex]2y=136[/tex]           divide both sides by 2

[tex]y=68[/tex]

Of the various sleep disorders, the most widespread is insomniadifficulty in falling or staying asleep. Insomnia may be due to a particular situation, such as the breakup of a relationship, concern about a test score, or the loss of a job. Often, however, insomnia has no obvious cause. Some people are simply unable to fall asleep easily, or they go right to sleep but then wake up frequently. Insomnia afflicts about a quarter of the population of the United States. Interestingly, many who think they have insomnia are mistaken. Observers find that patients who enter sleep laboratories for treatment may sleep much more than they think they do. For example, researchers report that some people who claim to be up all night actually fall asleep in thirty minutes and stay asleep all night. Furthermore, some people can accurately recall sounds they heard while asleep. As a result, they believe that they were awake during the night. In many cases, just becoming aware of how long they really do sleepand understanding that the older they become, the less sleep they needis enough to cure peoples perception that they have a sleep disorder. In fact, some researchers believe the twenty-first century will lead to drugs that act by changing peoples perceptions of how much they have slept, rather than making them sleep more. Other sleep problems are less common than insomnia and perceived insomnia, although they are still widespread. For instance, some 20 million people suffer from sleep apnea, a condition in which a person has difficulty breathing and sleeping simultaneously. The result is disturbed, fitful sleep, as the person is constantly reawakened when the lack of oxygen becomes great enough to trigger a waking response. In some cases, people with sleep apnea wake as many as 500 times during the course of a night, although they may not even be aware that they have wakened. Not surprisingly, such disturbed sleep results in complaints of fatigue the next day. Sleep apnea may also account for sudden infant death syndrome, a mysterious killer of seemingly normal infants who die while sleeping. Narcolepsy is an uncontrollable need to sleep for short periods throughout the day. People with narcolepsy go directly from wakefulness to sleep. No matter what the activityholding a heated conversation, exercising, even drivingthe narcoleptic will suddenly slip into sleep. The causes of narcolepsy are not known, although it appears to run in some families. 1. Which sentence best states the main idea of the passage? a.
