Determine the equation of the circle graphed below

The absolute threshold is defined as the minimum detectable stimulus or intensity.

The absolute threshold refers to the minimum amount or level of a stimulus that is required for it to be detected or perceived by an individual. It is the point at which a stimulus becomes perceptible or noticeable to a person.

In sensory psychology, the absolute threshold is typically measured in terms of the lowest intensity or magnitude of a stimulus that can be detected accurately by a person at least 50% of the time. It represents the boundary between the absence of perception and the presence of perception.

The absolute threshold can vary depending on the sensory modality being tested. For example, in vision, it may refer to the minimum amount of light required for a person to see an object. In hearing, it may represent the minimum sound intensity needed for an individual to hear a tone.

Several factors can influence the absolute threshold, including individual differences, physiological factors, and the nature of the stimulus itself. Factors such as sensory acuity, attention, fatigue, and background noise can all affect an individual's ability to detect a stimulus.

Answer: R = {0kg, 59.5kg}

Step-by-step explanation:

When we have a function f(x) = y.

The set of the possible values of x is called the domain of the function, and the set of the possible values of y is called the range of the function,

In this case, we have that:

the plant recycled 4.9kg the first hour, and 7.8 kg per hour after.

So this function can be written as piecewise function, with one part for the first hour, and another part for the time after the first hour.

F(x) = 4.9kg*x if 0h < x ≤ 1h

F(x) = 4.9kg + 7.8kg/h*(x -1) if x ≥ 1h

We use (x - 1) for the second part because if  x = 1 h, we must have the same result in both parts of the function.

Where x is the number of hours.

And we know that the domain is (0hours, 8 hours)

Then the minimum value of y will be:

F(0h) = 4.9kg*0h = 0kg.

And the maximum value in the range will be:

F(8h) = 4.9kg + 7.8kg*7  = 59.5kg

Then the range is:

R = {0kg, 59.5kg}

The blank words are:

Enlargement and 6.4.

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Given:

A company plans to scale its logo and place it on a billboard so that drivers and pedestrians can see it easily from the ground.

The original logo is a square with sides of 1.25 inches.

After scaling,

the local must have a perimeter of 32 feet.

This action is called enlargement,

and the scale factor is,

= (32/4) / 1.25

= 8 / 1.25

= 6.4.

Therefore, the scale factor is 6.4.

Step-by-step explanation:

The p-value is 1.0000 (rounded to four decimal places). This means that we fail to reject the null hypothesis, which in this case would be that the population mean is equal to the sample mean of 26.2.

To find the test statistic, we need to use the formula:

test statistic = (sample mean - population mean) / (standard deviation / square root of sample size)

Since the population standard deviation is given as 6, we can plug in the values:

test statistic = (26.2 - population mean) / (6 / √40)

To find the population mean, we can use the fact that the sample mean is an unbiased estimator of the population mean, so:

population mean = sample mean = 26.2

Plugging in the values, we get:

test statistic = (26.2 - 26.2) / (6 / √40) = 0

The test statistic is 0.

To find the p-value, we need to use a t-distribution table or calculator. Since we have a sample size of 40, we can use the t-distribution with 39 degrees of freedom.

Using a calculator or table, we can find that the area to the right of 0 (since the test statistic is 0) is 0.5. Since this is a two-tailed test, we need to double this value to get the p-value:

p-value = 2 * 0.5 = 1.0000

The range of the function f(x) = log5x is (-∞, +∞).The function f(x) = log5x represents the logarithm base 5 of x. To determine the range of this function, we need to consider the possible values that the logarithm can take.

The range of the logarithm function y = log5x consists of all real numbers. The logarithm function is defined for positive real numbers, and as x approaches 0 from the positive side, the logarithm approaches negative infinity. As x increases, the logarithm function approaches positive infinity.

The range of the function is the set of all possible output values. In this case, the range consists of all real numbers that can be obtained by evaluating the logarithm

log5(�)log 5 (x) for �>0 x>0.

Since the base of the logarithm is 5, the function log5x will take on all real values from negative infinity to positive infinity. Therefore, the range of the function f(x) = log5x is (-∞, +∞).

In other words, the function can output any real number, ranging from negative infinity to positive infinity. It does not have any restrictions on the possible values of its output.

a)  pn.P(c) = p1 + p2 + p3 + ... + pn

b)  P(c) = [p1 × p2] + [p1 × p3] + ... + [(n - 1)th power plant × nth power plant

a) Probability of city experiencing blackout. Probability of city experiencing blackout can be defined as: Probability of the first power plant failing, p1, plus the probability of the second power plant failing, p2, plus the probability of the third power plant failing, p3, and so on, up to probability of the nth power plant failing, pn.P(c) = p1 + p2 + p3 + ... + pn. The probability of experiencing a blackout in the city can be found by the equation mentioned above.

b) Probability of city experiencing blackout when two power plants fail. When two power plants are required to power the entire city, we can find the probability of experiencing a blackout by finding the probability of one plant failing and another one failing as well. P(c) = [p1 × p2] + [p1 × p3] + ... + [(n - 1)th power plant × nth power plant]Therefore, the probability that the city will experience a blackout is given by the formula above.

Answer:

The dimensions of the the party favor bag are;

Height = 14 inches

Width = 2 inches  

Length = 5 inches

Step-by-step explanation:

The given parameters are;

x³ + 6·x² - 27·x = 140

The dimensions of the party-favor bag are;

Height = (x + 9) inches

Width = (x - 3) inches

Length = x inches

The given equation can be rewritten as follows;

x³ + 6·x² - 27·x - 140 = 0

Using an online application, we have;

x³ + 6·x² - 27·x - 140 = 0 = (x + 4)·(x - 5)·(x + 7)

Therefore, x = -4, 5, or -7

Which gives x = 5, as the length of the party favor bag, x inches, cannot be negative;

Therefore, the dimensions of the the party favor bag are;

Height = (x + 9) inches = (5 + 9) inches = 14 inches

Width = (x - 3) inches = (5 - 3) inches = 2 inches  

Length = x inches = 5 inches.

The linear equation m = 9.50h + 140 represents the amount of money m earned by Mark in h hours while working at the grocery store in summer.

Mark earns $9.50 per hour while working at local grocery store

Total money earned by Mark after working for 16 hours is $292

As per the given condition, the points are (16, 292)

The slope of the linear equation is represented by $9.50

Hence, M = 9.5(16, 292)

Standard linear equation is given by

m = Mx + b … (1)

Substitute the values in the equation to get the values of b

292 = 9.5(16) + b

⇒ b = 292 - 152

⇒ b = 140

Substitute the values in the equation (1) again to get linear equation

⇒ m = 9.50h + 140

Hence, the linear equation is m = 9.50h + 140

The area οf a rectangle is the amοunt οf space enclοsed within the bοundary οf a rectangle. It is calculated by multiplying the length οf the rectangle by its width. If we denοte the length οf the rectangle by 'l' and its width by 'w', then the area οf the rectangle can be expressed as:

Area = length x width = l x w

Tο find οut hοw many tiles Mοira needs, we first need tο find the tοtal area οf her kitchen flοοr. We can dο this by multiplying the length and width οf the kitchen:

Area οf kitchen flοοr = length x width = 12' x 18' = 216 square feet.

Next, we need tο figure οut hοw many tiles will cοver this area. Tο dο this, we need tο divide the area οf the kitchen flοοr by the area οf each tile:

Area οf each tile = 1/2' x 3/4' = 3/8 square feet

Number οf tiles = (Area οf kitchen flοοr) / (Area οf each tile) = 216 / (3/8) = 576 tiles.

Finally, we can calculate the tοtal cοst οf the tiles by multiplying the number οf tiles by the cοst per tile:

Tοtal cοst οf tiles = (Number οf tiles) x (Cοst per tile) = 576 x $0.75 = $432.

Step-by-step explanation:

"Given :  a survey was conducted in a group of 100 students of a school. the ratio of students who like mathematics and computer is 3:5. if 30 of them like both subjects and 10 of them like none of them,

To Find : number of students who like:  at most one subject.

Solution:

Mathematics = 3k

Computer = 5k

30 of them like both subjects

10 of them like none of them

Total = Math + Computer - Both  + None

100 = 3k  + 5k   - 30  + 10

=> 120 = 8k

=> k = 15

Mathematics = 45

Computer =  75

Mathematics only   = Mathematics - Both = 45 - 30 = 15

Computer only  = Computer - Both =75 - 30  = 45

at most one subject  = 100 - Both subjects 100 - 30  =  70

or none + computer only + Mathematics only = 10 + 45 + 15 = 70

70 Students like at most one subject"
