As a result, the total area of the four triangles (PTA, PTB, PTC, and ABC) equation exceeds the size of T, which contradicts the premise that T has the greatest area.

A math equation is a technique that links two assertions and denotes equivalence using the equals sign (=). In algebra, an equation is a mathematical statement that proves the equality of two mathematical expressions. For example, in the equation 3x + 5 = 14, the equal sign separates the numbers 3x + 5 and 14. A mathematical formula may be used to understand the link between the two phrases written on either side of a letter. The logo and the programmed are usually interchangeable. As an example, 2x - 4 equals 2.  

The area of a triangle in hyperbolic geometry is determined by the formula:

Area = K ∙ (α + β + γ - π)

where K is a constant that depends on the curvature of the space and,, and are the triangle's angles.

we want to emphasise the expression + + -.

Consider the following two situations:

Case 1: T has angles that add up to be less than.

Moreover, the total of the areas of triangles PTA, PTB, and PTC is larger than the area of T since their angles add up to more than T's angles. As a result, the total area of the four triangles (PTA, PTB, PTC, and ABC) exceeds the size of T, which contradicts the premise that T has the greatest area.

Step-by-step explanation:

a submarine cant go above 0 and it shows on the graph the lowest it will go is -300

Answer:

approximately normal with mean=4.2 and standard deviation=0.3.

The sampling distribution of the sample mean is a normal distribution with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size. In this case, since the population mean is 4.2 cars and the population standard deviation is 3 cars, and we have a sample size of 100 days, then the sampling distribution of the sample mean will have a mean of 4.2 cars and a standard deviation of 3/sqrt(100) = 0.3 cars.

Step-by-step explanation:

The sampling distribution of the sample mean is the distribution of the mean of a sample of observations from a population. In this case, the sampling distribution of the sample mean would be a normal distribution with a mean of 4.2 and a standard deviation of 33/sqrt(100) = 1.6. This means that 68% of the time, the sample mean would be between 2.6 and 5.8, and 95% of the time, the sample mean would be between 1.6 and 7.8.

The sampling distribution of the sample mean is important because it can be used to make inferences about the population mean. For example, if the sample mean is 5.8, we can be 95% confident that the population mean is between 1.6 and 7.8.

Answer:

Sweater costs 56.00

To calculate the discounted price of the sweater

56 * (30/100) = 16.8

We used (30/100) to find out the 30 percent of the sweater which will be on discount/reduced.

56-16.8=39.2 is the discounted price

Then we subtract the amount of discount from the original price of sweater to find out the discounted price.

Answer:

If she wants the same number of each color in each bouquet and use all of her balloons, she can make 12 balloon bouquets.

With 7 blue balloons per bouquet and 8 white balloons per bouquet.

Step-by-step explanation:

The school colors are blue and white. Elizabeth had 84 blue balloons and 96 white balloons.

We solve this using GCF Method

The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

Then the greatest common factor is 12.

Therefore, If she wants the same number of each color in each bouquet and use all of her balloons, she can make 12 balloon bouquets.

The number of blue balloons in each bouquet =

84/12

= 7 blue balloons per bouquet

The number of white balloons in each bouquet =

96/12

= 8 white balloons per bouquet

The given cube has an edge of 2 feet, and its edge is increasing at the rate of 6 feet per minute. The volume of a cube is the product of the length of its edge three times. Let's solve this problem step by step.The volume of the cube with the edge of 2 feet is:V(2) = 2³ = 8 cubic feetLet's calculate the rate of increase in volume.

As the edge of the cube is increasing at the rate of 6 feet per minute, the new edge after m minutes will be 2 + 6m feet.Volume of the cube with an edge of 2 + 6m feet:

V(2 + 6m) = (2 + 6m)³ = (2³ + 3 x 2² x 6m + 3 x 2 x 6m² + 6m³) cubic feet= (8 + 36m + 54m² + 6m³) cubic feet

Therefore, the function of m can be written as:

V(m) = 8 + 36m + 54m² + 6m³

We are given that the cube has an edge of 2 feet and that the edge is increasing at the rate of 6 feet per minute. The volume of the cube is the product of the length of its edge, cubed.The volume of a cube with an edge of 2 feet is calculated as follows:V(2) = 2³ = 8 cubic feet.If the edge of the cube is increasing at the rate of 6 feet per minute, then the new edge after m minutes will be 2 + 6m feet. The volume of the cube with an edge of 2 + 6m feet is then calculated as follows:

V(2 + 6m) = (2 + 6m)³ = (2³ + 3 x 2² x 6m + 3 x 2 x 6m² + 6m³) cubic feet= (8 + 36m + 54m² + 6m³) cubic feet.

Therefore, the function of m can be written as:

V(m) = 8 + 36m + 54m² + 6m³,

which gives the volume of the cube as a function of the number of minutes elapsed, m.

Thus, we can conclude that the volume of the cube with an edge of 2 feet, increasing at the rate of 6 feet per minute can be calculated as V(m) = 8 + 36m + 54m² + 6m³.

Step-by-step explanation:

The probability that it will weigh between 687 grams and 825 grams is 90.47%

Using this formula, we can find the z-scores for the lower and upper bounds of the weight range we are interested in:

z₁ = (687 - 725) / 29 = -1.31

z₂ = (825 - 725) / 29 = 3.45

Next, we use a standard normal distribution table or calculator to find the probabilities associated with these z-scores.

Using the table, we find that the probability of a standard normal distribution up to z₁ = -1.31 is 0.0951, and the probability up to z₂ = 3.45 is 0.9998. To find the probability between these two z-scores, we subtract the smaller probability from the larger one:

P(-1.31 < z < 3.45) = 0.9998 - 0.0951 = 0.9047

Therefore, the probability of picking a fruit that weighs between 687 grams and 825 grams is 0.9047, or 90.47% (rounded to 4 decimal places).

The maintenance cost expected to be incurred during July is $9,400. This corresponds to option C in the given choices.

To determine the maintenance cost expected to be incurred during July, we need to substitute the planned machine time of 9,000 hours into the cost formula Y = $5,800 + $0.40X.

Plugging in X = 9,000 into the formula, we get:

Y = $5,800 + $0.40(9,000)

Y = $5,800 + $3,600

Y = $9,400

Therefore, the maintenance cost expected to be incurred during July is $9,400. This corresponds to option C in the given choices.

The cost formula Y = $5,800 + $0.40X represents the fixed cost component of $5,800 plus the variable cost component of $0.40 per machine-hour. By multiplying the planned machine time (X) by the variable cost rate, we can determine the additional cost incurred based on the number of machine-hours. Adding the fixed cost component gives us the total maintenance cost expected for a given level of machine-time. In this case, with 9,000 hours of planned machine time, the expected maintenance cost is $9,400.

The alternative hypothesis states that the difference is greater than zero.

What Are Tails in a Hypothesis Test?

First, we need to cover some background material to understand the tails in a test. Typically, hypothesis tests take all of the sample data and convert it to a single value, which is known as a test statistic. You’re probably already familiar with some test statistics.

For example, t-tests calculate t-values. F-tests, such as ANOVA, generate F-values. The chi-square test of independence and some distribution tests produce chi-square values. All of these values are test statistics.

Keep in mind that this t-distribution assumes that the null hypothesis is correct for the population. Consequently, the peak (most likely value) of the distribution occurs at t=0, which represents the null hypothesis in a t-test. Typically, the null hypothesis states that there is no effect. As t-values move further away from zero, it represents larger effect sizes. When the null hypothesis is true for the population, obtaining samples that exhibit a large apparent effect becomes less likely, which is why the probabilities taper off for t-values further from zero.

Hence the answer is the alternative hypothesis states that the difference is greater than zero.

To locate the discontinuities of the function y = ln(tan^2x), we need to find the values of x where the function is not continuous.

First, let's consider the domain of the natural logarithm, ln(x). It is defined only for positive values of x, so tan^2x must be greater than 0 for the function to be defined.

Next, let's consider the domain of tan(x). Tan(x) is undefined when its denominator, cos(x), is equal to 0. This occurs at x = (2n + 1)π/2, where n is an integer.

Since we have tan^2x, the square of tan(x) will always be non-negative. However, we need it to be positive (greater than 0) for ln(tan^2x) to be defined. Tan^2x will be equal to 0 when tan(x) is 0, which occurs at x = nπ, where n is an integer.

Thus, the discontinuities of the function y = ln(tan^2x) occur at two different sets of x values:

1. x = (2n + 1)π/2, where n is an integer, due to the undefined nature of tan(x).
2. x = nπ, where n is an integer, due to tan^2x being 0, which is not in the domain of ln(x).

There are infinitely many discontinuities because of the variable n.

'x' only has one solution

Step-by-step explanation:

First multiply both sides by 'x^2'

40x = -5x^2

(bring both values to one side and factorize to solve for 'x')

5x^2 +40x=0

5x(x+8)=0

5x= 0 ; x+8 = 0

x=0 ; x=-8

x cannot equal to '0' as zero cannot be a denominator.

Hence, x=-8 is the only correct solution.

So, 'x' only has one solution.

The radial distances from the center (-3, -2), to the points on the circumference (0, -6), and (a, 0), found using the distance formula, indicates that a = -3 ± √21

The distance between points (x₁, y₁), and (x₂, y₂), on the coordinate plane, can be found using the formula; d = √((x₂ - x₁)² + (y₂ - y₁)²).

The coordinates of the center of the circle = (-3, -2)

The coordinates of the locations (on the circumference of the circle), through which the circle passes = (0, -6) and (a, 0)

Therefore the distances between points (0, -6) and (-3, -2) and (a, 0) and (-3, -2) are the same;

The distance from (0, -6) to (-3, -2) = The distance from (a, 0) to (-3, -2)

(-3 - 0)² + (-2 - (-6))² = (-3 - a)² + (-2 - 0)²

25 = a² + 6·a + 9 + 4 = a² + 6·a + 13

a² + 6·a + 13 = 25 (symmetric property)

a² + 6·a + 13 - 25 = 0

a² + 6·a - 12 = 0

a = (-6 ± √(6² - 4×1×(-12)))/(2×1) = (-6 ± √(84))/2

a = (-3 ± √(21))
