the answer to the question is 5.20XY cubed.

How to solve the problem?

The square root of 18 X to the seventh power Y to the sixth power can be simplified using the laws of exponents and radicals. First, we can express 18 as a product of its prime factors: 18 = 2 x 3 x 3. Then, we can write X to the seventh power as X to the sixth power times X, and Y to the sixth power as Y to the third power squared.

So, we have:

Square root of 18 X to the seventh power Y to the sixth power

= Square root of (2 x 3 x 3) X to the sixth power X Y to the third power squared

= Square root of 2 X to the sixth power Y to the third power squared times 3

= Square root of 2 X to the sixth power Y to the third power squared times square root of 3

Using the laws of exponents and radicals, we can simplify the square root of 2 X to the sixth power Y to the third power squared as X cubed Y cubed, and we can approximate the square root of 3 as 1.73. Therefore:

Square root of 18 X to the seventh power Y to the sixth power

= X cubed Y cubed times square root of 3

= 3XY cubed times 1.73

= 5.20XY cubed (rounded to two decimal places)

So, the answer to the question is 5.20XY cubed.

Answer:

£2947

Step-by-step explanation:

the formula for simple interest is interest = prt.

p is the principal value, or what omar had at the beginning.

r is the rate at that you gain interest.

t is the amount of time in years.

so, plugging in our values, we multiply 2800*3*0.0175 to get 147.

now, since that was the amount of interest omar gained, we still have to add the original amount that he had, and 2800+147 = 2947.

so, the answer is £2947.

Answer:

6, 2, and 3 would all also be 64° angles. 1, 4, 5, and 8 would all be 116° angles.

Step-by-step explanation:

Since 64° and 5 make up a supplementary angle (180°) just do the equation 180°-64° to get 116°. From there know that 64° and angle 6 must be equal (using the same logic from supplementary angles) then angles 2 and 3 must also be equal. Then apply that to angle 5 (which is 116°) and angle 8, as well as angles 1 and 4.

The probability that your mail will be delivered before 2 pm for 2 consecutive days is 0.81.

Given,

The probability that your mail is delivered before 2 pm is 0.90.

Answer: To write 6^-5 in expanded form, we need to first recall the definition of negative exponents. If a number a is raised to a negative exponent, it means that we take the reciprocal of a raised to the absolute value of the exponent. In other words:

a^(-n) = 1 / a^n

Using this definition, we can write:

6^-5 = 1 / 6^5

Now, we can expand 6^5 using repeated multiplication or by using a calculator. 6^5 means 6 multiplied by itself five times:

6^5 = 6 × 6 × 6 × 6 × 6 = 7776

Therefore, we can write:

6^-5 = 1 / 6^5 = 1 / 7776

So, the expanded form of 6^-5 is 1/7776.

Step-by-step explanation:

The theoretical probability is 0.5 and the experimental probability is 0.583

Part A:

Since the coin is fair, the probability of it landing on heads is 0.5 or 50%.

The theoretical probability of a fair coin landing on heads is 0.5.

Part B:

Let's denote the outcome of flipping the coin as H (heads) or T (tails). We flip the coin 12 times and record the frequency of each outcome:

NB: This is an assumption and not a given data;

Outcome Frequency

    H              7

    T                      5

The experimental probability of landing on heads is calculated by dividing the number of times the coin landed on heads by the total number of coin flips:

Experimental probability of landing on heads = number of heads / total number of flips

Experimental probability of landing on heads = 7 / 12 = 0.583

Part C:

Comparing the experimental probability to the theoretical probability, we can see that they are different. The theoretical probability is 0.5, while the experimental probability is 0.583. This difference can be attributed to the randomness of the coin flips and the fact that we only flipped the coin 12 times, which is a relatively small sample size. As we increase the number of coin flips, the experimental probability should converge to the theoretical probability.

Answer:

[tex]22^\circ + m\angle C = 90^\circ[/tex]

Step-by-step explanation:

Pre-Solving:

We are given that [tex]\angle A[/tex] (which is equal to 22°) and [tex]\angle B[/tex] are vertical angles, and that [tex]\angle B[/tex] is complementary to [tex]\angle C[/tex].

We want to write an equation that will help us solve [tex]\angle C[/tex].

Solving:

Recall that vertical angles are congruent by vertical angles theorem.

This means that [tex]\angle A \cong \angle B[/tex]; it also means that the measure of [tex]\angle B[/tex] is also 22°.

Also recall that complementary angles add up to 90°.

This means that [tex]m\angle B + m\angle C = 90^\circ[/tex].

Since we deduced that [tex]m\angle B[/tex] is 22°, we can substitute that value into the equation.

Hence, an equation that can be used to solve for [tex]\angle C[/tex] is:

[tex]22^\circ + m\angle C = 90^\circ[/tex]

Answer:

m∠A = m∠B

m∠A = 22°

m∠B + m∠C = 90°

Step-by-step explanation:

∠A and ∠B are vertical angles. (Given)

By definition of vertical angles, a pair of angles with the same vertex and that are on opposite sides of two intersecting straight lines are congruent.

It is given that ∠A is 22°, and is a vertical angle with ∠B.

∴ ∠A ≅ ∠B (Definition of Vertical Angles).

IF m∠A = 22° and ∠A ≅ ∠B, THEN m∠B = 22° (Transitive Property of Equality).

∠B is complementary with ∠C (Given)

m∠B + m∠C = 90° (given).

m∠B = 22° (⇒Transitive Property of Equality)

Plug in 22 for m∠B in the given equation:

22 + m∠C = 90

Isolate the term, m∠C. Note the equal sign, what you do to one side, you do to the other. Subtract 22 from both sides of the equation:

m∠C + 22 (-22) = 90 (-22)

m∠C = 90 - 22

m∠C = 68°

~

Therefore, your system of equation will be:

m∠A = m∠B

m∠A = 22°

m∠B + m∠C = 90°

Answer:

Step-by-step explanation:

You want the edge length of a cube whose space diagonal is 7√3 cm.

The square of the face diagonal of a cube of edge length s is ...

  d² = s² +s² = 2s²

The square of the space diagonal is found by applying the Pythagorean theorem again. The space diagonal is the hypotenuse of a right triangle whose legs are one cube edge and the face diagonal.

  D² = s² +d² = s² +2s² = 3s²

  D = √(3s²) = s√3

So, we want to find s when D = 7√3:

  s√3 = 7√3

  s = 7

The edge length of the cube is 7 cm.

The odds of answering at least 9 questions correctly out of 15 by choosing at random is approximately 0.120

To solve this problem, we can use the binomial distribution, which models the probability of getting a certain number of successes in a fixed number of independent trials, each with the same probability of success.

In this case, we have 15 independent trials (the 15 questions) and the probability of success in each trial is 1/4 (the probability of guessing the correct answer among 4 choices). We want to find the probability of getting at least 9 successes.

Using a binomial distribution calculator, we can calculate this probability as

P(X ≥ 9) = 1 - P(X < 9) = 1 - binomcdf(15, 1/4, 8) ≈ 0.120

where binomcdf is the cumulative distribution function of the binomial distribution, which gives the probability of getting up to a certain number of successes (in this case, up to 8). The complement of this probability (1 minus the probability of getting up to 8 successes) gives the probability of getting at least 9 successes.

Using Trigonometric functions, the height of the tree is approximately 50.6 feet.

Let's call the height of the tree "h" and the distance between the forester's original position and the base of the tree "x". Then, when the forester moves 20 feet closer to the tree, the distance between the new position and the base of the tree is "x - 20".

We can use the tangent function to set up two equations relating the height of the tree to the angles of elevation:

tan(37°) = h/x ...(1)

tan(52°) = h/(x - 20) ...(2)

We can solve this system of equations to find the value of "h". First, we can rearrange equation (1) to get:

x = h/tan(37°)

Then, we can substitute this expression for "x" into equation (2) and solve for "h":

tan(52°) = h/(h/tan(37°) - 20)

Simplifying and solving for "h", we get:

h = (20 tan(52°) tan(37°)) / (tan(52°) - tan(37°))

Using a calculator, we can evaluate this expression and find that:

h ≈ 50.6 ft

Therefore, the height of the tree is approximately 50.6 feet.

a. To rationalize the expression √√√4 + x = 3 3, we need to get rid of the cube roots in the denominator.

First, we simplify the cube root of 4:

√√√4 = √√2

So, our expression becomes:

√√2 + x = 3 3

To get rid of the cube root in the denominator, we need to multiply both sides by the conjugate of the denominator:

(3 - √2)(√√2 + x) = 3

Expanding the left side:

3√√2 + 3x - 2√2 - √2√√2x = 3

Simplifying:

3x - 2√2 - √2√√2x = 3 - 3√√2

Combining like terms:

(3 - √2)x = 3 - 3√√2 + 2√2

Simplifying:

(3 - √2)x = (3 + 2√2) - 3√√2

Dividing both sides by (3 - √2):

x = [(3 + 2√2) - 3√√2]/(3 - √2)

Simplifying:

x = (3 + 2√2)(3 + √2)/7

b. To rationalize and solve for x in the expression 1-√2:

We need to get rid of the radical in the denominator by multiplying both the numerator and denominator by its conjugate:

1 - √2 / 1 - √2 * 1 + √2 / 1 + √2

Simplifying, we get:

(1 - √2)(1 + √2) / (1 - √2)(1 + √2)

= 1 - 2

= -1

So, x = -1.

Therefore, the rationalized expressions are:

The standard error of the average sample weight is 7.32 when 15 participants are randomly selected for the sample, rounded to two decimal places

The standard error of the average sample weight is calculated by dividing the standard deviation by the square root of the sample size. In this case, the standard error of the average sample weight is 35/√15 = 7.32. Thus, the standard error of the average sample weight is 7.32 when 15 participants are randomly selected for the sample. To calculate the standard error of the average sample weight, it is important to first determine the standard deviation of the population.

The standard deviation of the population, in this case, is 35. This is because it was found from the historical data that the weight of the participants is normally distributed with a mean of 175 lbs and a standard deviation of 35 lbs. Next, the standard deviation is divided by the square root of the sample size. In this case, the sample size is 15 participants. Thus, the standard deviation is divided by the square root of 15 (√15) which results in the standard error of the average sample weight which is 35/√15 = 7.32.

What is close polynomial and open polynomial?

The terms "closed polynomial" and "open polynomial" are not commonly used in mathematics. However, we can talk about sets of polynomials being open or closed.

In general, a set of polynomials is said to be open if, for any polynomial in the set, there is a small "neighborhood" of polynomials around it that is also contained in the set. Intuitively, this means that the set "opens up" in all directions around any point in the set.

A set of polynomials is said to be closed if it contains all of its limit points. In other words, if a sequence of polynomials in the set converges to a polynomial outside of the set, then that polynomial must be added to the set to make it closed.

For example, the set of all quadratic polynomials with a nonzero discriminant is closed under addition, scalar multiplication, and multiplication of polynomials, so it is a closed set. The set of all cubic polynomials with real coefficients is an open set, since for any cubic polynomial, we can find a small "neighborhood" of cubic polynomials around it by adjusting the coefficients slightly.

6.The polynomial set {(x² + x − 4) - (x²+x+8)} is equivalent to the set {-12}. A single point set like this is neither open nor closed in the usual topologies on the real numbers.

7.The polynomial set (2-x)(1 + 3x) is the set of all polynomials of degree at most 2 with a leading coefficient of -3. This set is closed under addition, scalar multiplication, and multiplication of polynomials, so it is a closed set.

8.The polynomial set (5b-3c)(7b - 3c) is equivalent to the set {25b² - 36bc + 9c²}, which is the set of all quadratic polynomials in b and c with a nonzero discriminant. This set is not closed under addition, since the sum of two polynomials in this set can have a zero discriminant. Therefore, it is not a closed set.
