600° C

Answers

Answer 1

The value of T is 428°C.

How to calculate temperature from resistance?

To solve the problem, we can start by substituting the given value of R = 13946 into the equation R = 10000 + (4124 x 10^-2)T – (1779 x 10^-5)T^2 and solving for T. This gives us a quadratic equation in T which can be solved using the quadratic formula.

After simplifying, we get T = 427.67°C or T = -88.22°C. However, we know that the thermometer is only used if T ≤ 600°C, so the only valid solution is T = 427.67°C.Therefore, the temperature corresponding to a resistance of 13946 ohms is approximately 428°C.

It's important to note that this assumes the thermometer is operating within its specified range and that the resistance-temperature relationship remains linear over the given temperature range.

lizzie came up with a divisibility test for a certain number m that doesn't equal 1:

-break a positive integer n into two-digit chunks, starting from the ones place. (for example, the number 354764 would break into the two-digit chunks 64, 47, 35.)

- find the alternating sum of these two-digit numbers, by adding the first number, subtracting the second, adding the third, and so on. (in our example, this alternating sum would be 64-47+35=52.)

- find m, and show that this is indeed a divisibility test for m (by showing that n is divisible by m if and only if the result of this process is divisible by m).

Answers

Lizzie's divisibility test works for numbers that are multiples of 11.

How does Lizzie's divisibility test work?

Lizzie's divisibility test for a number m works as follows: break a positive integer n into two-digit chunks, find the alternating sum of these two-digit numbers, and if the result is divisible by m, then n is also divisible by m.

For example, if we have a number n = 354764, we would break it into the two-digit chunks 64, 47, and 35, then find the alternating sum of these numbers (64 - 47 + 35 = 52).

If we want to test if n is divisible by m = 4, we check if 52 is also divisible by 4. If 52 is divisible by 4, then we can conclude that 354764 is also divisible by 4.

Assuming an approximately normal data set, find the 68% confidence interval for systolic blood pressure in
women given a sample size of 1000 with a mean of 123.4 and a standard deviation of 19.9.

Answers

There is not enough evidence to conclude that Devon's true proportion of good serves is greater than 72%.

Find out the 68% confidence interval for systolic blood pressure in women from the given samples?

The correct conclusion for Devon to reach is: Because the P-value of 0.06 > a (where a = 0.05), Devon should fail to reject H0. There is no convincing evidence that the proportion of services that are good is more than 72%.

The null hypothesis, H0, states that the true proportion of good serves for Devon is equal to 72%. The alternative hypothesis, Ha, states that the true proportion of good serves for Devon is greater than 72%.

The P-value is the probability of obtaining a test statistic as extreme or more extreme than the observed data, assuming that the null hypothesis is true. In this case, the P-value is 0.06, which means that if the true proportion of good serves for Devon is actually 72%, there is a 6% chance of observing a sample of 50 serves with 42 or more good serves.

Since the P-value is greater than the significance level of 0.05, we fail to reject the null hypothesis.

The 68% confidence interval for systolic blood pressure in women, based on the given sample, is approximate: (122.77, 124.03)

How to find a confidence interval for systolic blood pressure in women?

To find the 68% confidence interval for systolic blood pressure in women, we can use the standard formula:

Confidence Interval = Mean ± (Z * (Standard Deviation / √n))

Where:

Mean = 123.4 (sample mean)

Standard Deviation = 19.9 (sample standard deviation)

n = 1000 (sample size)

Z = Z-score corresponding to the desired confidence level (in this case, 68% corresponds to 1 standard deviation on each side of the mean)

To find the Z-score, we can refer to the standard normal distribution table or use a calculator. For a 68% confidence level, the Z-score is 1.

Plugging in the values, we get:

Confidence Interval = 123.4 ± (1 * (19.9 / √1000))

Calculating the square root of 1000, we have:

Confidence Interval = 123.4 ± (1 * (19.9 / 31.62))

Simplifying further, we get:

Confidence Interval = 123.4 ± (0.6301)

Therefore, the 68% confidence interval for systolic blood pressure in women, based on the given sample, is approximate: (122.77, 124.03).

What is triangle?

A triangle is a three-sided polygon, which is a closed shape made up of straight lines. It is one of the simplest geometric shapes and is used extensively in mathematics, science, and engineering. In a triangle, each side connects two vertices or corners, and each vertex is where two sides intersect. The three angles of a triangle always add up to 180 degrees, and the sum of the lengths of any two sides is always greater than the length of the third side. Triangles can be classified by the lengths of their sides and the sizes of their angles, which gives rise to different types such as equilateral, isosceles, scalene, acute, right, and obtuse triangles. Triangles have many applications, such as in geometry, trigonometry, physics, and engineering, and they are fundamental to understanding the properties of other shapes and mathematical concepts.

Here,

In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. So, for this triangle, we have:

sin(53°) = opposite / hypotenuse

sin(53°) = x / 53

To solve for x, we can rearrange the equation as follows:

x = 53 * sin(53°)

Using a calculator to evaluate sin(53°), we get:

sin(53°) = 0.7986 (rounded to four decimal places)

Substituting this value into the equation, we get:

x = 53 * 0.7986

x = 42.308 (rounded to two decimal places)

The volume of the unoccupied space inside the cube is the volume of the cube minus the volume of the ball, which is approximately 166.

1. D. Cone. When a tree is cut down, its trunk typically has a roughly cylindrical shape with a tapered end, which closely resembles a cone.

2. B. 166. The diameter of the ball is 11 cm, which is also the length of the diagonal of the cube. Let's call the side length of the cube "s". Then, we can use the Pythagorean theorem to find s:

s^2 + s^2 + s^2 = 11^2

3s^2 = 121

s^2 = 121/3

The volume of the cube is s^3, which is approximately 166. The volume of the ball is (4/3)πr^3, where r is the radius of the ball. Since the ball fits tightly inside the cube, its diameter is equal to the side length of the cube, which is s√3. Thus, r = (s√3)/2 - 5.5.

Answers

There is no convincing evidence that the proportion of Devon's serves that are good is more than 72%. The data collected does not provide sufficient evidence to support Devon's claim that he has a higher proportion of good serves than what his coach stated.

Based on Devon's hypotheses, H₀ states that p = 72%, while Hₐ states that p > 72%, where p represents the true proportion of Devon's good serves. To test this, 50 of his serves are randomly selected, and 42 are good. A simulation is conducted with 100 trials, resulting in an estimated P-value of 0.06. The significance level (α) is set at 0.05.

In this case, the P-value (0.06) is greater than the significance level (0.05). According to the rules of hypothesis testing, we should fail to reject the null hypothesis (H₀) when the P-value is greater than the significance level. Therefore, Devon should fail to reject H₀.

The line of regression equation for the mileage rating of a ( point) four wheel drive vehicle is [tex]\hat y = 16.111 + 0.365x,[/tex] and the best predicted new mileage rating of a ( point) four-wheel drive vehicle when x = 19 mi/gal, is equals to the 23.046 mi/gal. So, option(b) is right one.

A linear regression line has an equation of the form [tex]\hat y = a + bx,[/tex]

where x is the independent variable and y is the dependent variable. The slope of the line is b, and a is the estimated intercept (the value of y when x = 0). We have a table form data of old and new rating of four-wheel-drive vehicles. We have to determine the line of regression. Now, we have to calculate the value of 'a' and 'b'. Let the old and new mileage rating of four-wheel-drive vehicles be represented by vaiables 'x' and 'y'. Using the following formulas, [tex]b =\frac{ S_{xy}}{S_{xx}}[/tex] where, [tex]S_{xx} = \sum x² - \frac{ (\sum x)² }{n} [/tex]

[tex]S_{xy} = \sum xy - \frac{ (\sum y \sum x) }{n}[/tex][tex]a = \bar y - b \bar x,[/tex]

where , [tex]\bar x = \frac{\sum x }{n}[/tex]

[tex]\bar y = \frac{\sum y }{n}[/tex]

Here, n = 11, [tex]\sum x[/tex] = 235

[tex]\sum xy[/tex] = 263, [tex]\sum x²[/tex] = 5733, [tex]\sum xy[/tex] = 5879, so

[tex]S_{xx}[/tex] = 5733 - (235)²/11

= 5733 - 5020.454 = 712.546

[tex]S_{xy}[/tex] = 5879 - (235×263)/11

= 260.364

Now, b = 260.364/712.546 = 0.365

a = (263/11) - 0.365 ( 235/11)

= 23.909 - 7.798

So, regression line equation is

[tex]\hat y = 16.111 + 0.365x,[/tex]

The best predicted value of y, when x = 19 mi/gal, [tex]\hat y = 19× 0.365 + 16.111[/tex]

A circle is circumscribed around a regular octagon with side lemgths of 10 feet. Another circle is inscribed inside the octagon. Find the area. Of the ring created by the two circles. Round the respective radii of the circles to two decimals before calculating the area

Answers

The area of the ring created by the two circles is approximately 1374.63 square feet.

Let's first find the radius of the circumscribed circle. We can draw a diagonal of the regular octagon, which will be twice the length of one of its sides, forming an isosceles triangle with two radii of the circle.

The angle at the center of the circle between two adjacent sides of the octagon will be 360 degrees divided by 8, or 45 degrees.

The angle at the top of the isosceles triangle will be half of that, or 22.5 degrees. Using trigonometry, we can find the radius of the circumscribed circle:

[tex]$\sin(22.5^\circ) = \frac{opposite}{hypotenuse}$$\sin(22.5^\circ) = \frac{10}{2r}$$r = \frac{10}{2\sin(22.5^\circ)} \approx 21.21$[/tex]

Next, we can find the radius of the inscribed circle. Drawing radii from the center of the octagon to the points where it touches the circle, we can form 8 congruent isosceles triangles, each with a base of length 10 and two equal legs.

The angle at the top of each triangle will be half of the central angle between two adjacent sides of the octagon, or 22.5 degrees. Using trigonometry again, we can find the length of each leg of the triangle:

[tex]$\tan(22.5^\circ) = \frac{opposite}{adjacent}$$\tan(22.5^\circ) = \frac{r'}{5}$$r' = 5\tan(22.5^\circ) \approx 2.93$[/tex]

Now we can calculate the area of the ring created by the two circles:

[tex]$A = \pi R^2 - \pi r'^2$$A = \pi (21.21)^2 - \pi (2.93)^2 \approx 1374.63$ square feetTherefore, the area of the ring created by the two circles is approximately 1374.63 square feet.\\\\\\\\[/tex]

A function is a rule that assingns each value of independent variable to exactly value of the dependent variable

Answers

A function is a rule that assingns each value of independent variable to exactly one value of the dependent variable.

A function is a mathematical concept that relates two sets of values, known as the domain and the range. The domain is the set of independent variables, while the range is the set of dependent variables. A function is a rule that assigns to each value in the domain exactly one value in the range.

For example, if we have a function f(x) = 2x + 3, the domain would be any possible value of x, and the range would be any possible value of 2x + 3. So if we put x = 2, then f(x) = 2(2) + 3 = 7. Therefore, the function assigns the value of 7 to the value of 2 in the domain.

A new car is purchased for 29,000 and over time it’s value depreciates by one half every 3. 5 years what is the value of the car 20 years after it was purchased to the nearest hundred dollars

Answers

The required answer is the nearest hundred dollars: $902.09 is approximately $900.

To find the value of the car 20 years after it was purchased, we can use the formula for exponential decay:

Value = Initial value * (1 - Depreciation rate) ^ (time elapsed / time for depreciation)

1. Determine the depreciation rate: The car's value depreciates by one half every 3.5 years, so the depreciation rate is 50% or 0.5.
Depreciation is a term that refers to two aspects of the same concept: first, the actual decrease of fair value of an asset, such as the decrease in value of factory equipment each year as it is used and wears, and second, the allocation in accounting statements of the original cost of the assets to periods in which the assets are used (depreciation with the matching principle).

Depreciation is thus the decrease in the value of assets and the method used to reallocate, or "write down" the cost of a tangible asset (such as equipment) over its useful life span


2. Calculate the number of depreciation periods: Since the car's value halves every 3.5 years, we need to find out how many 3.5-year periods are in 20 years. To do this, divide 20 by 3.5: 20 / 3.5 ≈ 5.71 periods.

3. Use the exponential decay formula:
Value = 29,000 * (1 - 0.5) ^ (5.71)
Value ≈ 29,000 * (0.5) ^ (5.71)
Value ≈ 29,000 * 0.0311
Value ≈ 902.09

4. Round the value to the nearest hundred dollars: $902.09 is approximately $900.

So, the value of the car 20 years after it was purchased is approximately $900.

What is triangle?

It is one of the simplest polygon shapes and is commonly used in mathematics and geometry. The sum of the internal angles of a triangle is always 180 degrees.

Define vertices of triangle?

The vertices of a triangle are the three points in a two-dimensional (2D) or three-dimensional (3D) space that define the corners or corners of the triangle. In a 2D plane, the vertices are typically denoted as A, B, and C, and in a 3D space, they can be represented as (x1, y1, z1), (x2, y2, z2), and (x3, y3, z3) where (x, y, z) are the coordinates of each vertex along the x, y, and z axes respectively. The vertices of a triangle are connected by three line segments, known as edges, to form the sides of the triangle. The combination of the three vertices and the edges connecting them determines the shape and size of the triangle.

To find the scale factor used to dilate triangle ABC to A'B'C', we can compare the corresponding side lengths of the two triangles.

The distance between A(-3, -3) and B(3, 3) is √((3-(-3))^2 + (3-(-3))^2) = 6√2.

The distance between A'(-6, -6) and B'(6, 6) is √((6-(-6))^2 + (6-(-6))^2) = 12√2.

So the scale factor used to dilate triangle ABC to A'B'C' is:

scale factor = length of corresponding side in A'B'C' / length of corresponding side in ABC

            = (12√2) / (6√2)

            = 2

Therefore, the scale factor used is 2.

Suppose two types of wire will be used to form the edges of a rectangle. The wire used
for the width costs $2.50 per foot and the wire used for the height costs $4.25 per foot. Express the total cost of building the rectangle out of wire as a function of the with if the
enclosed area must be 500 square feet.

Answers

To start, let's call the width of the rectangle "w" and the height "h". We know that the area must be 500 square feet, so we can write an equation:

w*h = 500

We can solve this equation for h:

h = 500/w

Now we can express the total cost of the wire in terms of w. The cost of the wire for the width is $2.50 per foot, so the cost for that side is:

2.5w

The cost of the wire for the height is $4.25 per foot, so the cost for that side is:

4.25h = 4.25(500/w) = 2125/w

So the total cost of the wire is:

C(w) = 2.5w + 2125/w

This is our final answer expressed in function notation.
Let's denote the width of the rectangle as w and the height as h. We are given that the area of the rectangle must be 500 square feet, so we have:

w * h = 500

Now, we need to find the cost function based on the width. The cost of the wire for the width is $2.50 per foot and for the height is $4.25 per foot. Therefore, the total cost (C) can be expressed as:

C(w) = 2.50 * w + 4.25 * h

We need to express the height (h) in terms of the width (w) using the area equation:

h = 500 / w

Now, we can substitute this expression for h in the cost function:

C(w) = 2.50 * w + 4.25 * (500 / w)

This is the cost function for building the rectangle out of wire as a function of its width, given that the enclosed area must be 500 square feet.

Two similar cylinders have heights 6cm and 30cm. The volume of the smaller cylinder is 90cm3. What is the volume of the larger cylinder?

Answers

Answer:

Step-by-step explanation:

Since the two cylinders are similar, their corresponding dimensions (radius and height) are proportional. Let the radius of the smaller cylinder be r.

Then, we can write:

r / 6 = R / 30

where R is the radius of the larger cylinder.

Simplifying this equation, we get:

R = 5r

Now, we can use the formula for the volume of a cylinder to find the volume of the larger cylinder:

Volume of smaller cylinder = πr^2h = 90 cm^3

Volume of larger cylinder = πR^2H = π(5r)^2(30) = 750πr^2 cm^3

Substituting R = 5r, we get:

Volume of larger cylinder = 750πr^2 cm^3

Therefore, the volume of the larger cylinder is 750π times the volume of the smaller cylinder:

Volume of larger cylinder = 750π(90 cm^3) = 67,500π/ cm^3 (approx. 211,239.74 cm^3 rounded to five decimal places).
