Answer:

2nd choice:  144.53 ft²

Step-by-step explanation:

Area of base = 6 x 7 = 42

Area of 2 sides with 8 ft height = 2 · (1/2)(6)(8) = 48

Area of 2 sides with 7/79 ft height = 2 · (1/2)(7)(7.79) = 54.53

Total SA = 42 + 48 + 54.53 = 144.53 ft²

The missing portions of the proof are:

2) ∠4 ≅ ∠1 ; ∠3≅∠2 - Corresponding Angles Theorem

3) CDB ≅CEA           -     AA Similarity

The other information that could have been stated to proof that Angle - Angle similarity is: Angle C ≅ angle C

Reflexive Property

The reflexive property of equality in algebra asserts that a number is always equal to itself. Equality has a reflexive attribute. If an is a positive integer, then a = a.

When two parallel lines cross by any other line (i.e. the transversal), corresponding angles are generated in matching corners or corresponding angles with the transversal.

So in the above proof, ∠4 ≅ ∠1 ; ∠3≅∠2 because they are a pair of corresponding angels because they are created in matching corners.

Looking at the shape, we can see that CDB  and CEA   are triangles since we have established that their angles are similar, hence, the Angle Angle Similarity postulate.

Answer:

Step-by-step explanation:

In direct variation, the relationship between two variables x and y can be represented by the equation y = kx, where k is the constant of variation.

To find the value of k, we can substitute the given values of x and y into the equation:

y = kx

12 = k(2)

Solving for k, we can divide both sides by 2:

k = 6

Now we can write the direct variation equation using the value of k:

y = 6x

Therefore, the direct variation equation that shows the relationship between x and y is y = 6x.

We can use the inverse normal distribution function to find the z-score corresponding to the desired percentile, and then use the formula for standardizing a normal variable to find the corresponding raw score.

The score that separates the top 53% from the bottom 47% on an English test with a normal distribution, mean of 37.6, and standard deviation of 7.6 can be found using the inverse normal distribution function.

We need to find the z-score that corresponds to the 53rd percentile. We can do this using a standard normal distribution table or a calculator. The z-score corresponding to the 53rd percentile is approximately 0.07.

We can use the formula for standardizing a normal variable to find the corresponding raw score: z = (X - mean) / standard deviation Rearranging this formula, we get: X = z * standard deviation + mean

Plugging in the values we have: X = 0.07 * 7.6 + 37.6 X ≈ 38.2 A score of approximately 38.2 separates the top 53% from the bottom 47% on this English test.

The required situation that can be represented by the equation 18x = 19 + 12x is:

"J. Krystal can make $18 per hour by tutoring. Jondo can make $12 per hour by tutoring. Jondo already has $19. How many hours, x, would Krystal and Jondo need to tutor for them to have the same amount of money?"

Let Krystal and Jondo work for x hours. Then Krystal would make 18x dollars, and Jondo would make 12x + 19 dollars (Jondo already has 19 dollars).

The equation 18x = 12x + 19 represents the situation where Krystal and Jondo make the same amount of money. Solving this equation gives:

18x - 12x = 19

6x = 19

x = 19/6

Approximate height to the statue's actual height of 120 feet, 3 inches from heel to top of head is 123.75 feet.

To estimate the height of the statue, the student can use the method of similar triangles. Since the length of the statue's right arm is 45 feet and the length of the student's right arm is 2 feet, the ratio of the lengths of the arms is 45/2 = 22.5. If we assume that the ratio of the heights of the statue and the student is also 22.5, then the height of the statue can be estimated as:

height of statue = height of student x ratio of heights

height of statue = 5.5 x 22.5

height of statue = 123.75 feet

This estimated height of the statue is close to the actual height of 120 feet, 3 inches. It should be noted that this method of estimation assumes that the ratio of the heights of the statue and the student is the same as the ratio of the lengths of their arms. This may not be completely accurate, as the proportions of the statue and the student may be different.

The list of elements of each set are as follows:-

U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

A = {1, 3, 5, 7, 9}

B = {2, 4, 6, 8, 10}

C = {2, 4, 5, 6, 7, 9}

A set in mathematics is a collection of unique objects, referred to as elements or members, that are paired off according to some shared quality.

For instance, 1, 2, 3, 4, 5, 6, 7, and 8 make up the set of all natural numbers that are less than 10. There are several ways to describe sets, including by describing its components, using set builder notation, or by utilising set operations.

Given that-

U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

A = {1, 3, 5, 7, 9}

B = {2, 4, 6, 8, 10}

C = {2, 4, 5, 6, 7, 9}

Set U contains all the numbers from 1 to 10, so U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.

Set A contains only the odd numbers from 1 to 10, so A = {1, 3, 5, 7, 9}.

Set B contains only the even numbers from 1 to 10, so B = {2, 4, 6, 8, 10}.

Set C contains the numbers that are in both A and B, so C = {2, 4, 5, 6, 7, 9}.

The likelihood of the agent making 2 sales out of 8 appointments is 0.132.

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain to occur.

The probability of making a sale on any appointment is 1/5, and the probability of not making a sale is 4/5.

We can use the binomial distribution to find the probability of making 2 sales out of 8 appointments

P(2 sales) = (8 choose 2) × (1/5)² × (4/5)⁶

where (8 choose 2) = 28 is the number of ways to choose 2 appointments out of 8.

So, plugging in the values, we get

P(2 sales) = 28 × (1/5)² × (4/5)⁶

= 0.132

To find the equation for d, the distance in meters that Martin covers per second, we need to use the formula:

distance = speed × time

Here, the distance covered by Martin is 100 meters, and the time taken is 15 seconds. Therefore, we can write:

distance = speed × time

100 meters = speed × 15 seconds

To find the speed, we can rearrange the equation as:

speed = distance / time

speed = 100 meters / 15 seconds

So the speed of Martin is:

speed = 6.67 meters per second

Therefore, the correct equation for d, the distance in meters that Martin covers per second, is:

d = speed

d = 6.67 meters per second

Answer: There is no option that matches the correct equation for d, which is simply d = 6.67 meters per second.

The given statement "To find the sample of a population it is always necessary to take into account all the information of the problem" is false because a sample can be selected using random sampling techniques that do not require knowledge of the entire population.

It is not always necessary to take into account all the information of the problem to find a sample of a population. In many cases, a sample can be selected using random sampling techniques that do not require knowledge of the entire population. However, it is important to ensure that the sample is representative of the population, and this often requires careful consideration of the characteristics of the population.

If the problem already has the population defined and we want to estimate a parameter such as the mean or proportion, we can use the formula that only involves the standard deviation of the population, known as the standard error. For example, if we want to estimate the mean of a population, we can use the formula

SE = σ / √n

Where SE is the standard error of the mean, σ is the standard deviation of the population, and n is the sample size. By calculating the standard error, we can then use it to construct confidence intervals and conduct hypothesis tests about the population mean.

However, it is important to note that in many cases we do not know the standard deviation of the population and need to estimate it from the sample. In such cases, we use the sample standard deviation as an estimate of the population standard deviation, and use a t-distribution instead of a normal distribution to construct confidence intervals and conduct hypothesis tests.
