The measure of  the angles <ABC and <CBD are 48⁰ and 42⁰

The angle ABC and angle CBD are complementary angles, m <ABC=(3x+6)⁰ and m<CBD=(4x-14)⁰

The angles are complementary which means that they sum to 90⁰

Therefore, we get: <ABC + <CBD = 90⁰

3x + 6 + 4x - 14 = 90 ------ Substituting 3x + 6 and 4x - 14 for < ABC and <CBD

7x = 98

x= 98/7 = 14⁰

Sentence B: "The joke was so hilarious that the audience smirked!" is not vivid enough to describe the action as the audience reaction is not clearly defined. Smirking is usually a subtle expression that might be difficult to interpret.

Sentence C: "The joke was so hilarious that the audience smiled!" is also not vivid enough to describe the action as smiling is a common reaction to something funny and it doesn't clearly convey the level of audience's reaction.

The  difference in the account balances at the end of the loan terms is, $1770.87. So option B is correct

Simple interest is an amount which is calculated for a certain period of time and for a certain rate, in simple interest calculation there are three factors which we consider: principal amount(P), rate(R) and time(T).

Every time we calculate simple interest the principal values will be the same unlike compound interest.

Formula;    Simple Interest(I) =  P × R × T/100

Given that,

Offer 1-  5.99% annual simple interest, with a total account balance of $32,487.50 after a 60-month term Offer

Offer 2-  3.75% annual interest compounded monthly for a 66-month term

In offer 1,

Total amount A  = $32487.50

In offer 2,

Total amount =

[tex]A = P[ 1 + r/n]^{nt}[/tex]

[tex]A = 25000[ 1 + 0.0375/12]^{12*5.5}[/tex]

A = $30,716.63

Difference = 32487.50 - 30716.63

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Random sampling is the sampling method that was used.

Random sampling is a method in which all members of the population have an equal chance of being selected for the sample. In this case, fifteen instructors were chosen using random numbers to implement the new learning strategy.Random sampling is a useful tool when a researcher needs to select a representative sample from a population. By using random numbers to choose the sample, the researcher can ensure that the sample is truly representative of the population. Random sampling also helps to reduce bias, as the researcher has no control over who is chosen for the sample.

To calculate the probability of being chosen for the sample, the formula is (1/n) x 100, where n is the total number of population members. In this case, the population was the group of all instructors, and the sample was the group of fifteen instructors chosen. Therefore, the probability of being chosen is (1/n) x 100 = (1/15) x 100 = 6.67%.

A cosine and sine function can be expressed in terms of an imaginary exponential using Euler's formula: e^(iθ) = cos(θ) + i*sin(θ).

This formula can be derived by using the Taylor series for e^x, and replacing x with iθ.

A cosine and sine function can be expressed in terms of an imaginary exponential using Euler's formula: e^(iθ) = cos(θ) + i*sin(θ).

Conversely, an imaginary exponential can be expressed in terms of cosine and sine by solving for θ in the above equation. This can be done by taking the inverse cosine and inverse sine of both sides to get θ = cos^(-1)(e^(iθ)) = sin^(-1)(i*sin(θ)). Combining these equations gives θ = sin^(-1)(i*(e^(iθ) - cos(θ))).

The probability that Federer missed his first serves given that he won the point is 0.30%.

Generally, To solve this problem, we can use Bayes' theorem. Bayes' theorem states that:

P(A|B) = P(B|A) * P(A) / P(B)

where

A and B are events, and

P(A|B) is the probability of event A given that event B has occurred.

In this problem, let A be the event that Federer missed his first serve, and let B be the event that he won the point.

We are trying to find P(A|B), the probability that Federer missed his first serve given that he won the point.

We know that:

P(A) = 1 - 0.63 = 0.37 (the probability that Federer missed his first serve, given that he made 63% of his first serves)

P(B|A) = 0.57 (the probability that Federer won the point given that he missed his first serve)

P(B|A') = 0.78 (the probability that Federer won the point given that he made his first serve)

We can use these probabilities and Bayes' theorem to find the answer:

P(A|B) = P(B|A) * P(A) / ( P(B|A) * P(A) + P(B|A') * P(A'))

P(A|B) = 0.57 * 0.37 / ( 0.57 * 0.37 + 0.78 * 0.63)

Answer: To find the two integers between which the solution to 4^x = 50 lies, we can take the logarithm base 4 of both sides of the equation: x = log4(50). The logarithm of 50 with base 4 is approximately 2.3219. Since the logarithm of a number is always positive, the solution to 4^x = 50 lies between 2 and 3.

To find the exact solution, we can change the equation to logarithmic form by taking the logarithm base 4 of both sides: log4(4^x) = log4(50)

Using the logarithmic identity: log(b^x) = x*log(b)

So we have: x*log(4) = log(50)

Dividing both sides by log(4), we have:

x = log(50) / log(4)

To find the exact solution we can approximate log(50) / log(4) using a calculator or logarithm tables. The exact solution is x ≈ 2.32192809488736218170856773213.

So, the exact solution is x = 2.32192809488736218170856773213, which is between 2 and 3, as stated before.

Answer:

The two numbers are 17 and 7

Step-by-step explanation:

Translate this word problem into a math equation

If we let x and y be the two unknown numbers

One-half the sum of two numbers is 12 ==>

So one equation is 1/2(x + y) =12

Multiplying throughout by 2 gets rid of the denominator:
2 x 1/2 x (x + y) = 2 x 12

x + y = 24   (1)

One of the numbers is three more than two times the other number:
x = 2y + 3

or

x - 2y = 3  (2)

Equation (2) - Equation (1) =>

x + y - (x -2y) = 24 - 1
x + y - x + 2y = 21

3y = 21

y = 21/3

y = 7

With y = 7, substituting in equation 1 gives

x + y = 24

x + 7 = 24

x = 24-7

x = 17

The two numbers are 17 and 7
