What does a coefficient of determination of 0.8 mean?

The value of x is 44.

The most basic type of triangle is an equilateral triangle, which has three sides of equal length and three equal angles. Another common type of triangle is the right triangle, which has one right angle (90 degrees) and two other angles that add up to 90 degrees. Scalene triangles have no sides or angles of equal length, while isosceles triangles have at least two sides of equal length.

Triangles have many interesting and useful properties that can be used in geometry and other areas of mathematics. For example, the Pythagorean Theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side. This theorem can be used to find the length of a missing side in a right triangle.

Triangles also have an important relationship with circles. The circumcenter of a triangle is the center of the circle that passes through all three vertices of the triangle, while the incenter of a triangle is the center of the circle that is tangent to each of the triangle's sides.

From the triangle angle sum theorem, we know that the sum of all angles in a triangle is 180 degrees. So for triangle ABC, we have:

angle ABC + angle BCA + angle CAD = 180

50 + (3x - 10) + 2x = 180

Combining like terms and solving for x, we get:

5x = 220

Therefore, x = 44.

We know that the mean μ is:

μ = 4:30 p.m.

The standard deviation  is:

σ = 0:15 minutes

The Z-score is: Z = (x-μ)/σ

We seek to find probability P(4:00 p.m. < x < 5:00 p.m.)

The Z-score is:

Z = (x-μ)/σ = 4:00 - 4:30/0:15 = -2

The score of Z =-2 means that 4:00 p.m. is -2 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the condition of 2 deviations from the mean has percentage of 2.35% and

Z = (x-μ)/σ = 5:00 - 4:30/0:15 = 2

The score of Z =2 means that 11:00 p.m. is 2 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the condition of 2 deviations from the mean has percentage of 2.35%.

∴ P(4:00 p.m. < x < 5:00 p.m.) = 100% - 2.35% - 2.35%

The function that represents the amount of air required to inflate the balloon from a radius of r inches to a radius of r+3 inches is f(r) = 12π(r² + 3r + 3).

In this question, we are asked to determine a function for a spherical balloon that represents the amount of air required to inflate the balloon from a radius of r inches to a radius of r+3 inches.

Volume of spherical balloon = V(r) = 4/3 π r³

If the radius of balloon is r+3 inches = V(r+3) = 4/3 π (r+3)³

The amount of air required is the difference between V(r) and V(r+3):

So, f(r) = V(r+3) - V(r) = 4/3 π (r+3)³ - 4/3 π (r)³

                                  = 4/3 π ((r+3)³ -r³)

                                  = 4/3 π (r+3 -r)((r+3)² + r(r+3) + r²)

                                  = 4π(r² + 9 + 6r + r²+3r + r²)

                                  = 4π(3r² + 9r + 9)

                             f(r) = 12π(r² + 3r + 3)

Hence, the function representing is f(r) = 12π(r² + 3r + 3).

If the baker uses all their 72 ounces of flour in one day to make loaves of bread, they will make 6 loaves of bread. That is also 84 loaves of bread if they make loaves of bread for 2 weeks straight.

Step-by-step explanation:

Answer:

Step-by-step explanation: Well, one lbs (pound) is equal to 16 oz (ounces)

So take the 4.5 lbs and multiply it by the 16 oz. That'll give you 224 oz

Then take the 224 oz and multiply that by 14, which is the number of days from two weeks. 224 multiplied by 14 is 3,136

Step-by-step explanation:

Answer: 1/6 of a pound

Step-by-step explanation: Hello!

You know that Miss Collier bought a block of cheddar cheese that weighs 2/3 of a pound and she split it into four equal pieces.  This can be represented by the equation below:

2/3 divided by 4 = weight of a single slice of cheese

2/3 divided by 4/1 = weight of a single slice of cheese

Take the reciprocal of 4/1.  4/1 turns into 1/4.  Then multiply the two fractions.

2/3 x 1/4 = weight of a single slice of cheese.  

Multiply the numerators and denominators.  2 x 1 = 2, 3 x 4 = 12.

2/12 = weight of a single slice of cheese.

You can simplify this by dividing the numerator and denominator by 2.  2/2 = 1, 12/2 = 6.

The final answer is: 1/6 of a pound.

The initial amount in  Lea's account is 1212.12. Option A is the correct option.

What is the principal amount?

The amount you owe at any given time is the principal amount. When you first took out the loan, it is exactly your loan amount. The principal amount drops as you make EMI payments, and when it reaches zero, your loan is closed.

Given that  Lea earned $800 in simple interest on her investment after 11 years.

The formula of simple interest is

I = Prt.

P = Principal, r = rate of interest, t = time.

The rate of interest is r = 6% = 0.06, interest I = 800, time = 1 years.

Now putting the value of I, r,t in I = Prt:

800 = P×0.06×11

800= 0.66 P

Divide both sides by 0.66:

P = 800/0.66

P = 1212.1212

P = 1212.12(approx)

The minimum amount of number of divisions made by Euclid's algorithm among all inputs 1 to 10 is 0, as the greatest common divisor of any two numbers between 1 and 10 must be 1. The maximum number of divisions made by Euclid's algorithm among all inputs 1 to 10 is 19, as the greatest common divisor of 8 and 10 requires 19 divisions.

Euclid's algorithm is an efficient method for finding the greatest common divisor (GCD) of two integers. It works by repeatedly dividing larger numbers by smaller numbers until the remainder is 0. The GCD of two integers is then equal to the smaller number. The minimum number of divisions made by Euclid's algorithm among all inputs 1 to 10 is 0, as the GCD of any two numbers between 1 and 10 must be 1. This is because any two numbers between 1 and 10 have only 1 as their common divisor. On the other hand, the maximum number of divisions made by Euclid's algorithm among all inputs 1 to 10 is 19, as the GCD of 8 and 10 requires 19 divisions. This is due to the fact that 8 and 10 have no common divisors except for 1, so the algorithm must divide 8 by 10 repeatedly until the remainder is 0. Thus, the maximum number of divisions made by Euclid's algorithm among all inputs 1 to 10 is 19.

Under the unbiased expectations theory of the term structure of interest rates, the expected one-year interest rate one year from now, E(2r1), is 10%.

The unbiased expectations theory states that the expected future rate (E(2r1)) is equal to the current rate (1R2). Therefore, the expected one-year interest rate one year from now, E(2r1), is 10%.

The unbiased expectations theory is a principle in finance that states that the expected future rate of return (E(2r1)) is equal to the current rate of return (r2). This theory suggests that market participants have rational expectations and their expectations are reflected in the current market prices. In other words, the theory posits that the current market prices incorporate all available information and reflect the best prediction of future prices.

In the example given, if the expected one-year interest rate one year from now is 10%, it means that market participants believe that the one-year interest rate in the future will be 10%. This expectation is reflected in the current market prices and is incorporated into the current rate of return.

The magnitude of the net force is 149.33 N.

a) To illustrate the net force F1 + F2 as a geometric addition of the two force vectors, we can use the tail-to-tip method to add the vectors head-to-tail and then connect the tail of the first vector to the tip of the second vector to form the net force vector.

b) To compute the net force as the vector sum of the two force vectors, we can use the components of the two vectors to find the components of the net force. Using the trigonometric relationship between the angle and the components of a force vector, the x and y components of the force vectors can be calculated as follows:

F1x = F1 * cos(30) = 86.6025 N

F1y = F1 * sin(30) = 50 N

F2x = F2 * cos(45) = 35.3553 N

F2y = F2 * sin(45) = 35.3553 N

The x and y components of the net force are found by adding the corresponding components of the individual force vectors:

Fnetx = F1x + F2x = 86.6025 N + 35.3553 N = 122 N

Fnety = F1y + F2y = 50 N + 35.3553 N = 85.3553 N

c) To compute the magnitude of the net force, we use the Pythagorean theorem to find the magnitude from the components:

Fnet = √(Fnetx² + Fnety²) = √(122² + 85.3553²) = 149.33 N

So, the magnitude of the net force is 149.33 N.

The slope of a tangent line to a graph of a function is a measure of how steeply the function is increasing or decreasing at a certain point. A tangent line is a line that just touches the graph at a single point and has the same slope as the graph at that point.

Here we need to find the slope of the tangent line to the graph of

The balance sheet is a financial statement that shows the assets, liabilities, and equity balances of an entity at a point in time.

Assets describe the things owned by the entity while liabilities refer to its debts.  The difference between assets and liabilities is the equity (or the portion of assets belonging to the owners).

Initial investment = $12,000

Retained Earnings = $1,291

Long-term loan = $9,982 ($12,000 - $2,018)

Land and building = $8,878

Equipment = $4,230

Cash $8,250

Inventory = $1,225

Accounts Receivable = $675

Accounts Payable = $485

Short-term loan = $500

Prepare Company X's balance sheet.

A sequence is characterised as one that adheres to a predetermined pattern. The following term is created by increasing or decreasing the previous word by a certain amount.

On occasion, an expression is followed by every term in the series. The general formula for an AP is T n = a + (n - 1) d.

Understanding the underlying pattern or rule that creates the sequence is necessary for formulating the general term an of the sequence. Finding a formula for the overall term of a series can be done in a number of ways, including:

1) Finding a pattern: In some cases, a pattern can be found by examining the terms of the sequence and looking for a common ratio or difference. For instance, the formula for the general term can be written as a = a1 + (n - 1)d, where a1 is the first term and d is the common difference, assuming the terms of a sequence are rising by a constant amount.

2) Recurrence relations are used to characterise some sequences. These relations define the nth term in terms of the phrases that came before it. If the recurrence relation, for instance, is a = an-1 + an-2, then the general term's formula can be discovered by resolving the recurrence relation.

3) Making use of generating functions: Sequences can be represented mathematically using generating functions. A formula for the general term of a sequence can be discovered by fiddling with the generating function.

47 degrees is the the angle measure of one of the base angles.

A triangle is a three-sided polygon that consists of three edges and three vertices.

We know that an isosceles triangle is composed of a vertex angle and two base angles.

The base angles are congruent to each other.

We also know that the sum of a triangle's angles is 180 degrees.

86+2x=180

Subtract 86 from both sides

2x=180-86

2x=94

Divide both sides by 2

x=47

Hence, 47 degrees is the the angle measure of one of the base angles.
