Answer: 77 degrees

Step-by-step explanation:

When looking at an arc, you use the inscribed angle theorem, which states that the measure of an inscribed angle is half of the measure of its interpreted arc. So since the measure of the arc is 154 degrees, you divide that by 2 and that will give you the measure of the angle, which is 77 degrees.

The value of x in its simplest radical form is (25)^1/3

When a given number is in the form of a whole number, it is said to be an integer. Thus it can not be in the form of a fraction or does not have a decimal part. Examples include: 20, 345, 10, etc.

Radical form is a type of number which is expressed with a square root. This it could give a whole number or a number with a decimal part as the final answer.

To solve for x in either as an integer or in its simplest radical form;

-42 = 8 - 2x^3

-42 - 8 = -2x^3

- 50 = -2x^3

divide through by -2 to have;

x^3 = 25

find the cube root of both sides,

x = 25^1/3

Therefore in it simplest radical form, the value of x is 25^1/3

The probability that an unprepared student, who can eliminate one possible answer on the first four multiple-choice questions and guess on all six questions, will answer at least four questions correctly on the test.

There are a total of 5 possible answers per question, so the probability of guessing the correct answer for any given question is 1/5. After eliminating one possible answer on the first four questions, the student has a 1/4 chance of guessing the correct answer for each of those questions.

For the remaining two questions, the student has a 1/5 chance of guessing the correct answer for each question. To calculate the probability of the student answering at least four questions correctly, we need to consider all possible outcomes where the student guesses at random.

There are 5^6 total possible outcomes, since there are 5 possible answers for each of the 6 questions. The number of ways the student can answer at least 4 questions correctly can be found by considering the possible combinations of questions that the student answers correctly.

There are 6 possible combinations of 4 questions that the student can answer correctly, and there are 15 possible combinations of 5 questions that the student can answer correctly.

There is only 1 possible combination where the student answers all 6 questions correctly. Therefore, the probability of the student answering at least 4 questions correctly is:

[(6 choose 4)(1/4)^4(3/4)^2] + [(15 choose 5)(1/4)^5(3/4)^1] + (1/5)^2 = 0.0194

So the probability that the student will answer at least four questions correctly is approximately 0.0194, or 97/500, when expressed as a fraction.

Assuming Boden does not add or take out any money, he would have $470.4 in the account after 4​ years.

Mathematically, simple interest can be calculated by using this formula:

S.I = PRT or S.I = A - P

Where:

Substituting the given parameters into the simple interest formula, we have;

S.I = 400 × 4.4/100 × 4

S.I = 400 × 0.044 × 4

S.I = $70.4.

Next, we would calculate the future value as follows;

S.I = A - P

Future value, A = S.I + P

Future value, A = $70.4 + $400

Future value, A = $470.4.

The Drake equation is an equation used to estimate the number of extraterrestrial civilizations in the Milky Way galaxy that may be capable of communicating with us. It has several terms, each of which represents a factor that affects the number of such civilizations. The terms are:

N = R* x fp x ne x fl x fi x fc x L

where N is the number of communicative civilizations in the Milky Way, R* is the rate of star formation in the galaxy, fp is the fraction of stars that have planets, ne is the average number of habitable planets per star with planets, fl is the fraction of habitable planets that develop life, fi is the fraction of planets with life that develop intelligent life, FC is the fraction of intelligent civilizations that develop the technology to communicate, and L is the length of time such civilizations last.

The Kepler mission was a space observatory launched by NASA to discover Earth-sized planets orbiting other stars. Its results are particularly relevant to the terms fp and ne of the Drake equation. The Kepler mission has allowed us to estimate the number of stars in our galaxy that have planets, and the number of these planets that are in the habitable zone, where temperatures are suitable for liquid water and potentially life as we know it.

Specifically, the Kepler mission has allowed us to estimate that fp is around 0.5, meaning that about half of all stars in the Milky Way have planets. It has also provided evidence that it is at least one since it has discovered many planets in the habitable zone of their stars. These estimates are important for determining the overall number of habitable planets in the galaxy and, therefore, the potential number of communicative civilizations.

In summary, the Kepler mission has provided important data for estimating the values of the terms fp and ne in the Drake equation, which is crucial for determining the number of communicative civilizations in the Milky Way.

This statement is False as the probability of intersection of two events is always less than the probability of union.

This assertion is untrue. Contrary to popular belief, the likelihood of two occurrences coming together is always higher than or on pair with the likelihood of them colliding.

The chance of two events A and B occurring together can be calculated using the following formula to see why:

According to this equation, the probability of A and B joining together is equal to the total of their individual probabilities less the likelihood of their colliding.

When we rewrite this calculation and focus only on the likelihood of the intersection, we obtain:

Now it is clear that the probability of the intersection is determined by subtracting the probability of their union from the sum of the probabilities of A and B.

P(A) and P(B) are both less than or equal to P(A B), since probabilities can never be negative. P(A + B) is therefore less than or equal to twice P(A + B) when they are added together. Thus, it follows:

This indicates that, contrary to what the original statement implied, the probability of the intersection is not greater than or equal to the probability of the union.

Answer:

0.4545...

Step-by-step explanation:

To convert a fraction to a decimal take the numerator (5) and divide it by the denominator (11):

5 ÷ 11 = 0.454545... the 45 keeps repeating because it's a repeating decimal

The remainder when a positive integer x leaves a remainder of 2 when divided by 8 and x+9 is divided by 8 is 5.

If the positive integer x leaves a remainder of 2 when divided by 8, then we can say that x = 8k + 2, where k is an integer.

Now, if we divide x+9 by 8, we get:

(x+9)/8 = (8k + 2 + 9)/8
         = (8k + 11)/8
         = k + (11/8)

So, the remainder when x+9 is divided by 8 is 11/8. However, since we are dealing with integers, the remainder can only be a whole number between 0 and 7.

Therefore, we need to subtract the quotient (k) from the expression above and multiply the resulting decimal by 8 to get the remainder:

Remainder = (11/8 - k) x 8

Since k is an integer, the only possible values for (11/8 - k) are -3/8, 5/8, 13/8, etc. The closest whole number to 5/8 is 1, so we can say that:

Remainder = (11/8 - k) x 8 ≈ (5/8) x 8 = 5

Therefore, the remainder when x+9 is divided by 8 is 5.

If a positive integer x leaves a remainder of 2 when divided by 8, then x can be expressed as 8k + 2, where k is an integer. To find the remainder when x+9 is divided by 8, we divide x+9 by 8 and subtract the quotient from the decimal part. The resulting decimal multiplied by 8 gives us the remainder. In this case, the decimal is 11/8, which is closest to 1. Thus, we subtract the quotient k from 11/8 and multiply the result by 8 to get the remainder of 5.

The remainder when a positive integer x leaves a remainder of 2 when divided by 8 and x+9 is divided by 8 is 5.

Answer:

The divisors of 20 are 1, 2, 4, 5, 10, and 20. A 6-sided dice has the numbers 1 to 6 on its faces. The probability of rolling a number that is a divisor of 20 is the number of favorable outcomes divided by the number of possible outcomes. There are four favorable outcomes (1, 2, 4, and 5) and six possible outcomes (1 to 6). Therefore, the probability is 4/6 or 2/3 or about 0.67.

dt(AB) = dt(A(t) * B(t)) = dt(A(t)) * B(t) + A(t) * dt(B(t)).

The ith row vector of matrix A can be represented as [ai1, ai2, ai3, ..., ain]. This means that the ith row vector consists of the elements in the ith row of matrix A.

Similarly, the jth column vector of matrix B can be represented as [bj1, bj2, bj3, ..., bjp]. This means that the jth column vector consists of the elements in the jth column of matrix B.

To find the (i, j) entry of the product AB, we can multiply the ith row vector of matrix A with the jth column vector of matrix B. This can be done by multiplying each corresponding element of the row vector with the corresponding element of the column vector and summing up the results.

For example, the (i, j) entry of AB can be calculated as:
(ai1 * bj1) + (ai2 * bj2) + (ai3 * bj3) + ... + (ain * bjp)

Now, let's consider a matrix function A(t) that represents an m × n matrix and a matrix function B(t) that represents an n × p matrix.

The derivative of the product AB with respect to t, denoted as dt(AB), can be calculated using the product rule of differentiation. According to the product rule, the derivative of AB with respect to t is equal to the derivative of A(t) multiplied by B(t), plus A(t) multiplied by the derivative of B(t).

In other words, dt(AB) = dt(A(t) * B(t)) = dt(A(t)) * B(t) + A(t) * dt(B(t)).

This formula shows that the derivative of the product AB with respect to t is equal to the derivative of B multiplied by A, plus A multiplied by the derivative of B.
