Answer:

∠ GFC = 70°

Step-by-step explanation:

∠ BFE and ∠ CBF are alternate angles and are congruent, that is

∠ BFE = 37°

∠ BFE , ∠ BFC and ∠ GFC lie on a straight line and sum to 180° , then

37° + 73° + ∠ GFC = 180°

110° + ∠ GFC = 180° ( subtract 110° from both sides )

∠ GFC = 70°

The probability distribution of X indicates the likelihood of observing different combinations of adults who hold the opinion that CEOs of large U.S. companies are overpaid. In this case, there is a 10.56% probability of neither adult holding the opinion, a 43.52% probability of one adult holding the opinion, and a 46.24% probability of both adults holding the opinion. This probability distribution provides insights into the distribution of opinions within a sample of two randomly selected adults from the population.

The probability distribution of the random variable X, representing the number of adults in a sample of two adults who believe CEOs of large U.S. companies are overpaid, is as follows:

X = 0: Probability of both adults not holding the opinion = (1 - 0.68) * (1 - 0.68) = 0.1056

X = 1: Probability of one adult holding the opinion and the other not holding the opinion = (0.68 * 0.32) + (0.32 * 0.68) = 0.4352

X = 2: Probability of both adults holding the opinion = 0.68 * 0.68 = 0.4624

Explanation and Calculation:

To calculate the probability distribution of X, we consider the possible combinations of adults in the sample who hold the opinion that CEOs of large U.S. companies are overpaid.

When X = 0, it means that neither of the two adults holds the opinion. The probability of an adult not holding the opinion is (1 - 0.68), and since we have two adults, we multiply the probabilities to get the joint probability of both adults not holding the opinion.

When X = 1, it means that one adult holds the opinion, while the other does not. There are two possible scenarios: the first adult holds the opinion and the second adult does not, or vice versa. The probability of an adult holding the opinion is 0.68, and the probability of an adult not holding the opinion is (1 - 0.68). We calculate the probabilities for both scenarios and sum them up.

When X = 2, it means that both adults hold the opinion. The probability of an adult holding the opinion is 0.68, and since we have two adults, we multiply the probabilities to get the joint probability of both adults holding the opinion.

By  reject the null hypothesis. And hence we conclude that the mean weight is less than 9.0 grams.

Let μ be the mean population weight of medicine in the bottle. We have to test the null hypothesis H₀ : μ =9 against the alternative hypothesis Hₐ : μ< 9 .

The sample mean and standard deviation of the given sample data can be calculated by using Excel.

And we get (Mean) x = 8.8 and s ≈ 0.2268

Since the same size n=830 and population standard deviation is not given, we use t -test.

The test statistic is given by

t = \(\frac{x - μ }{s/\sqrt{n} }\)

= (8.8 - 9.0) / 0.2268 / \(\sqrt{8\\\)

≈ -2.4942

Now the critical value of t with degrees of freedom df=n-1=7 at significance level α = 0.05 is given by

t* =  -1.8946  (-ve value for left-tailed test)

Thus, the critical region is (-α, -1.8946]  and the calculated t =-2.4942 lies within the critical region.

So, we reject the null hypothesis. And hence we conclude that the mean weight is less than 9.0 grams.

The probability of randomly choosing a 5-letter password for an internet web site that consists of only vowels is approximately 0.00026 (or 0.026%).

There are 5 vowels in the English alphabet (a, e, i, o, u). To create a 5-letter password using only vowels, we have 5 choices for each letter in the password. Therefore, the total number of possible 5-letter passwords made up of only vowels is 5^5 = 3125.

To find the total number of possible 5-letter passwords, we need to consider all 26 letters of the English alphabet. Since there are 26 choices for each letter in the password, the total number of possible 5-letter passwords is 26^5 = 11,881,376.

The probability of randomly choosing a 5-letter password for an internet web site that consists of only vowels is the number of possible 5-letter passwords made up of only vowels divided by the total number of possible 5-letter passwords:

P(password consists of only vowels) = 3125 / 11,881,376

Answer:

answer in the picture

Step-by-step explanation:

Step-by-step explanation:

2.

an isometry means the distance between any two points in the original space is the same as the distance between them in the second space.

rotation and translation are such isometries. they leave the original shape or curve unchanged in its inner structure but move it around.

so, the shapes in this question are visibly an isometry. the size and structure of the pre-image is the same as for the image. only its position changed.

4.

(x, y) -> (x-3, y+5) means that every point of the shape or curve is moved (translated) 3 units to the left (the x coordinate is decreased) and 5 units up (the y coordinate is increased).

6.

(x, y) -> (x+7, y-2) -> (x-3, y+2)

this means that first every point of the shape or curve is moved (translated) 7 units to the right and 2 units down, and then 3 units to the left and 2 units up.

in the end this means that every point moved 4 units to the right (no up or down changes, as the intermediate changes canceled each other out).

The zeros of the polynomial are: x = 1/2 (with multiplicity 1), x = 3 (with multiplicity 1), and x = 5/2 (with multiplicity 1).We have found all three real zeros of the polynomial, which confirms that there are no complex zeros.

f(x) = 2x³ - 112x² + 27x - 41x + 15

To find the zeros and their multiplicities of this polynomial, we can begin by using Descartes' Rule of Signs. Let's consider the sign changes in the coefficients:

There are 2 sign changes in the coefficients (from 2x³ to -112x² and then to 27x, and finally to -41x and 15), which means there are either 2 or 0 positive real zeros.

There are no sign changes when we replace x with -x, which means there are either 0 or 2 negative real zeros.

Thus, there can be either 0, 2, or 4 real zeros, but we cannot determine their exact number or location with Descartes' Rule of Signs alone.

Next, we can use the Upper and Lower Bound Theorem to limit our search for rational zeros. According to this theorem, any rational zero of the polynomial must be of the form p/q, where p is a factor of the constant term (15 in this case) and q is a factor of the leading coefficient (2 in this case). Therefore, the possible rational zeros of the polynomial are:

±1/2, ±1, ±3/2, ±5, ±15/2, ±30

We can use synthetic division or long division to check these possible rational zeros and see which ones are actually zeros of the polynomial. Doing so, we find that the rational zeros of the polynomial are:

x = 1/2 (with multiplicity 1), x = 3 (with multiplicity 1), and x = 5/2 (with multiplicity 1).

f(n) = 56 + 3(n − 1) is the correct option represents the formula for the sequence.

In arithmetic sequences, each term is made larger by the addition or removal of a constant called k. Unlike a geometric sequence, where each term increases by being multiplied by or divided by a fixed constant k,

If there is a consistent difference between the words in a sequence of numbers, the sequence is referred to as an arithmetic progression. Think about the mathematical progression where the numbers 5, 7, 9, 11, 13, and so on all have a common difference of 2.

An is defined as a1 + d(n - 1), where d is the average difference between terms in the series, and a1 is the first term.

Given data :

This is the formula of an arithmetic sequence.

f(n) =   a1 + d(n - 1)

The solution is: 1/7 is the probability of picking an even number and then picking an even number.

Here, we have,

we know that,

Probability = required outcome /all possible outcome

given that,

You pick a card at random. Without putting the first card back, you pick a second card at random. 1 2 3 4 5 6 7.

number of  possible outcome = 7

Let:

A = 1st time pick an even number

B =2nd time pick an even number

so, we get,

There are 3 even numbers in total,

for the 2nd time it will be 2 even numbers in total,

we have,

P(A) = 3/7

and,

P(B) =2/6

we know that,

The intersection between both events is equal to the product of both probabilities since the events are independent.

so, we get,

P (A∩B) = P(A). P(B)

             = 3/7 * 2/6

             = 1/7

Hence, 1/7 is the probability of picking an even number and then picking an even number.

We must find p′, q′ in order to calculate the confidence interval; the sample proportion is p′ = 0.842; This is the population proportion's point estimate. Since CL = 0.95 is the requested confidence level, = 1 – CL = 1 – 0.95 = 0.05 (2) (2) = 0.025.

For P, what is the confidence interval at 95 percent?

Since 95% of the area under the curve falls within this interval, the interval (-1.96, 1.96) serves as a 95% confidence interval for the standard normal distribution.

What is the 95 percent confidence interval for the population's proportion of smokers?
