Answer:

7 x 2.6

Step-by-step explanation:

the square root of 7 is exactly 2.645751311064591, so in this case I converted it to a smaller number, using tenths place.

solution:

7 x 2.6 = 18.2

Answer:

\( {7}^{ \frac{3}{2} } \)

Step-by-step explanation:

\( \sqrt{7} \: can \: also \: be \: written \: as \: {7}^{ \frac{1}{2} } \)

We can use this information to rewrite the original expression:

\(7 \times {7}^{ \frac{1}{2} } \)

7 can also be written as

\( {7}^{1} \)

Remember that when multiplying exponents, if they have the same base, we can add the exponents. Therefore:

\( {7}^{1} \times {7}^{ \frac{1}{2} } \\ {7}^{1 + \frac{1}{2} } \\ {7}^{1 \frac{1}{2} } \\ {7}^{ \frac{3}{2} } \)

The quadratic equation in the simplest Standard form, ²+bx+c, with solutions 2 = 2 + 6√7 and 2 = 2 - 6√7, is x² - 4x - 248.

A quadratic equation with the given solutions, we can start by using the fact that if a quadratic equation has solutions x = p and x = q, then it can be written in the factored form as (x - p)(x - q) = 0.

the solutions are 2 + 6√7 and 2 - 6√7. Therefore, the factored form of the quadratic equation is:

(x - (2 + 6√7))(x - (2 - 6√7)) = 0

To simplify this, we can expand the equation:

(x - 2 - 6√7)(x - 2 + 6√7) = 0

Now, let's apply the difference of squares formula:

(x - 2)² - (6√7)² = 0

Simplifying further:

(x - 2)² - 36 * 7 = 0

(x - 2)² - 252 = 0

Finally, we can rewrite the equation in the standard quadratic form, ax² + bx + c:

x² - 4x + 4 - 252 = 0

x² - 4x - 248 = 0

Therefore, the quadratic equation in the simplest standard form, ²+bx+c, with solutions 2 = 2 + 6√7 and 2 = 2 - 6√7, is x² - 4x - 248.

The largest country in Europe by population is Russia. With a population of over 144 million people, Russia holds almost twice as many inhabitants as the second-largest country in Europe, Germany.

The reason why Russia has the largest population in Europe is mainly due to its vast geographical area, which includes diverse ethnic groups and natural resources, thus supporting a larger population. Additionally, historical factors such as migration, urbanization, and economic growth have also contributed to Russia's high population numbers.

One of the main reasons for Russia's large population is its size. As the largest country in the world, Russia covers almost 1/8th of the world's landmass, providing ample room for its citizens to reside. Additionally, Russia's population growth has been influenced by various factors throughout history, including immigration, wars, and government policies. Despite declining birth rates in recent years, Russia's population remains the largest in Europe.

a) Julie's pool is filling at a faster rate than Elaina's pool.

b) Julie's pool initially contained more water than Elaina's pool.

c) After 30 minutes, Julie's pool will contain more water than Elaina's pool.

a. To determine which pool is filling at a faster rate, we can compare the values of the rate of filling for Julie's pool and Elaina's pool at any given time.

Let's calculate the rates of filling for both pools using the provided equation.

For Julie's pool:

y = 8,400 + 5.2x

Rate of filling is 5.2 gallons per minute.

For Elaina's pool:

At t = 0 minutes, the pool contained 7,850 gallons.

At t = 3 minutes, the pool contained 7,864.4 gallons.

Rate of filling for Elaina's pool from t = 0 to t = 3:

= (7,864.4 - 7,850) / (3 - 0)

= 14.4 / 3

= 4.8 gallons per minute.

Rate of filling is 4.8 gallons per minute.

As 5.2>4.8. So, Julie's pool is filling up at a faster rate than Elaina's pool, which remains constant at 4.8 gallons per minute.

b. To determine which pool initially contained more water, we need to evaluate the number of gallons in each pool at t = 0 minutes.

For Julie's pool: y = 8,400 + 5.2(0) = 8,400 gallons initially.

Elaina's pool contained 7,850 gallons initially.

Therefore, Julie's pool initially contained more water than Elaina's pool.

c. To determine which pool will contain more water after 30 minutes, we can substitute x = 30 into each equation and compare the resulting values of y.

For Julie's pool: y = 8,400 + 5.2(30)

= 8,400 + 156

= 8,556 gallons.

For Elaina's pool, we need to calculate the rate of filling at t = 7 minutes to determine the constant rate:

Rate of filling for Elaina's pool from t = 7 to t = 30: 4.8 gallons per minute.

Therefore, Elaina's pool will contain an additional 4.8 gallons per minute for the remaining 23 minutes.

At t = 7 minutes, Elaina's pool contained 7,883.6 gallons.

Additional water added by Elaina's pool from t = 7 to t = 30:

4.8 gallons/minute × 23 minutes = 110.4 gallons.

Total water in Elaina's pool after 30 minutes: 7,883.6 gallons + 110.4 gallons

= 7,994 gallons.

Therefore, after 30 minutes, Julie's pool will contain more water than Elaina's pool.

Answer:

The equation in standard form is:

x^2-40x-6000 = 0

Step-by-step explanation:

Let the length of the field be x yards.

Now the width of the field is 40 yards less than the length of the field.

Thus, the width of the field would be (x-40) yards

Now, to calculate the area of the field, we simply multiply the length of the field by the width of the field.

Hence;

Since the shape is rectangular, the area is the product of the length and that of the width

x(x-40) =6,000

x^2 -40x = 6,000

x^2-40x-6000 = 0

(A) A person's chance of experiencing neither symptom is 30%. (b) Seventy percent of people are likely to experience at least one symptom. (c) If a person has symptom B, there is a 25% chance that they will also have both symptoms.

(A) The individual exhibits neither symptom:

Let's write P(A) for the likelihood of having symptom A and P(B) for the likelihood of having symptom B. Given that 20% of people only have symptom A, 40% only have symptom B, and 10% only have both symptoms, the likelihood of having neither symptom can be determined as follows:

100% - P(A) - P(B) - P(both symptoms) - P(neither symptom)

P(none of the symptoms) = 100% – 20% – 40% – 10% = 30%

As a result, there is a 30% chance that a randomly selected person will exhibit neither symptom.

(b) At least one symptom is present in the person.

We can use the complement rule to calculate the likelihood that at least one symptom will be present. Neither symptom is the opposite of having at least one symptom. Because of this, P(at least one symptom) = 1 - P(neither symptom), and P(at least one symptom) = 1 - 0.30 = 0.70.

Therefore, there is a 70% chance that a randomly selected individual has at least one symptom.

(c) The person has both symptoms, given that they have symptom B:

To calculate this conditional probability, we use the formula:

P(both symptoms | symptom B) is equal to the product of P(both symptoms and symptom B) / P(symptom B).

We are informed that 40% of people only have symptom B whereas 10% have both symptoms. P(both symptoms | symptom B) = (10% / 40%) = 0.25 as a result.

Given that they have symptom B, a randomly selected person has a 25% chance of having both symptoms.

Answer:

A and C

Step-by-step explanation:

Statements B) BA ≅ BC and C) AE ≅ DE guarantee that ray BE bisects angle ABC.

Statement B states that BA is congruent to BC. This means that side AB is the same length as side BC. Since the bisector of an angle divides the opposite side into two segments with equal lengths, this guarantees that ray BE bisects angle ABC.

Statement C states that AE is congruent to DE. This means that the segments AE and DE have the same length. Since the bisector of an angle divides the opposite side into two segments with equal lengths, this guarantees that ray BE bisects angle ABC.

The other statements are not sufficient to guarantee that ray BE bisects angle ABC. For example, if BA is congruent to BD, this does not mean that the segments AE and DE have the same length. Similarly, if BD is congruent to DE, this does not mean that side AB is the same length as side BC.

If you know that p = .7, then the value of q is 0.3 (option b)

If you know that p = .7, the value of q can be calculated using the complement rule of probability, which states that the probability of an event occurring is equal to one minus the probability of that event not occurring. In other words, q is equal to one minus p.

Therefore, q = 1 - p = 1 - 0.7 = 0.3.

It is important to note that the sum of p and q should always equal one, as there are only two possible outcomes in a given event. In this case, the sum of p and q is 0.7 + 0.3 = 1, which confirms that the values are correct.

Rounding to the nearest whole number, we get that the score a student would need to have a 30th percentile score on the SAT is 1345.  Correct option is B.

To find the score corresponding to the 30th percentile, we need to use the standard normal distribution with a mean of 0 and a standard deviation of 1. We can convert the SAT score to a standard normal score using the formula:

z = (x - μ) / σ

where x is the SAT score, μ is the mean score (1509), and σ is the standard deviation (312).

To find the score corresponding to the 30th percentile, we need to find the z-score that has an area of 0.30 to its left. Using a standard normal table or calculator, we can find that the z-score corresponding to a 30th percentile is approximately -0.52.

Now we can use the formula to find the corresponding SAT score:

-0.52 = (x - 1509) / 312

Solving for x, we get:

x = -0.52 * 312 + 1509 = 1345.36

To dilate a figure, we multiply the coordinates of each vertex by the scale factor. In this case, the scale factor is k = 0.5. Let's perform the dilation and calculate the ratios of the perimeters and areas.

Original square vertices:

A(0, 0)

B(0, 4)

C(4, 4)

D(4, 0)

Dilated square vertices:

A'(0 * 0.5, 0 * 0.5) = A'(0, 0)

B'(0 * 0.5, 4 * 0.5) = B'(0, 2)

C'(4 * 0.5, 4 * 0.5) = C'(2, 2)

D'(4 * 0.5, 0 * 0.5) = D'(2, 0)

Now, let's calculate the ratios of the perimeters and areas:

Perimeter ratio:

Original perimeter = 4 + 4 + 4 + 4 = 16

Dilated perimeter = 2 + 2 + 2 + 2 = 8

Perimeter ratio = Dilated perimeter / Original perimeter = 8 / 16 = 0.5

Area ratio:

Original area = 4 * 4 = 16

Dilated area = 2 * 2 = 4

Area ratio = Dilated area / Original area = 4 / 16 = 0.25

Therefore, the ratio of the perimeters is 0.5 and the ratio of the areas is 0.25.
