The last month's payment for White family can be algebraically expressed as;

⇒ 2665 - d - 11m.

What is an expression?

Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that;

Cost of a new pool table = $2,665

Down payment = d dollars

And, The monthly payment = m dollars.

Since, we have to given a duration of twelve months, we will have to subtract one month from 12 to give, 11 months.

Hence, We can formulate an algebraic equation as;

2665 - d - 11m.

Thus, The last month's payment for White family can be algebraically expressed as;

⇒ 2665 - d - 11m.

\(830\%\)

Answer:

Fraction: 8.3x10/10 = 83/10

percentage: 83/10 × 100/1 = 830%

Answer:

D- 5hrs

Step-by-step explanation:

If the family can hike 3 miles per hour,
for 15 miles: 15/3 = 5 hours.

Every hour they cover 3 miles per hour, so to cover 15 miles, they will take 5 hours

Answer:

D. 5 hours

Step-by-step explanation:

3 miles per 1 hour so 3/1

15 miles per x hours so 15/x

3/1 = 15/x or 3 = 15/x

get x by itself so

3 divided by 3 and 15 divided by 3

x = 5 hours

Answer: if you insert each x and y coordinate into the equations you will be able to figure out that option A will give you an answer of 10=16 and 1=3 which isn't correct. And so we do this for B and C until D is correct and matches with 6=6 and 3=3.

It will be best defined as a spurious correlation rather a casual correlation.

What is a spurious correlation?

A spurious correlation occurs when two variables are correlated but don’t have a causal relationship. In other words, it appears like values of one variable cause changes in the other variable, but that’s not actually happening.

If you look up the definition of spurious, you’ll see explanations about something being fake or having a deceitful nature. It has the outward appearance of genuineness, but it’s an imitation. With this definition in mind, spurious correlations look like causal relationships in both their statistical measures and in graphs, but it’s not real.

For example, ice cream sales and shark attacks correlate positively at a beach. As ice cream sales increase, there are more shark attacks. However, common sense tells us that ice cream sales do not cause shark attacks. Hence, it’s a spurious correlation.

The area of triangle ΔAFD found using trigonometric ratios to find the leg lengths FD and FA is 24.5·√3 square units

Trigonometric ratios expresses the relationship between two sides of a right triangle and an interior angle of the right triangle.

The specified parameters are;

m∠F in ΔAFD = 90°

The length of the hypotenuse side, AD = 14

The measure of angle ∠D, m∠D = 30°

The area of a triangle = Half base length × Height

The area of the triangle ΔAFD = (1/2) × FD × FA

The trigonometric ratios for cosines, indicates that we get;

cos(∠D) = FD/AD

Therefore;

FD = AD × cos(∠D)

Plugging in the values, we get;

FD = 14 × cos(30°)

FD = 14 × (√3)/2 = 7·√3

FD = 7·√3

The trigonometric ratios for sines indicates that we get;

sin(∠D) = FA/AD

Therefore; FA = AD × sin(∠D)

FA = 14 × sin(30°) = 7

FA = 7

ΔAFD = (1/2) × 7·√3 × 7 = (49·√3)/2

The area of triangle ΔAFD, A = 24.5·√3 square units

The statement with the inequalities are:

a. In △HEY, m∠1 is > m∠4.

b. In △HEY, m∠1 is = m∠4 + m∠6.

c. In △HEY, m∠3 is > m∠5.

d. In △HEY, m∠2 is > m∠6.

e. In △HEY, m∠4 is < m∠3​.

We have,

From the figure,

m∠1, m∠3 and m∠2 are exterior angles.

So,

m∠1 = m∠4 + m∠6

m∠3 = m∠5 + m∠4

m∠2 = m∠5 + m∠6

Now,

a.

In △HEY,

m∠1 is  > m∠4.

In △HEY,

m∠2 is > m∠6.

e.

In △HEY,

m∠3 = m∠5 + m∠4

m∠4 = m∠3 - m∠5

The angles can not be negative.

So,

m∠4 is < m∠3​.

Thus,

a. In △HEY, m∠1 is > m∠4.

To use the quadratic formula, we need to identify the values of a, b, and c.

1. In this case, the equation is 4x² - 3x - 8 = 0, so a = 4, b = -3, and c = -8.

2. x = (-b ±√(b² - 4ac))/2a.

3.  x = (3 ±√137)/8.

The Quadratic Formula is a mathematical equation used to solve second-degree equations.

To use the quadratic formula, we need to identify the values of a, b, and c in the equation ax² + bx + c = 0.

In this case, the equation is

4x² - 3x - 8 = 0,

so a = 4, b = -3, and c = -8.

Once the values of a, b, and c are known, we can substitute them into the Quadratic Formula:

x = (-b ±√(b² - 4ac))/2a.

In this equation, a = 4, b = -3, and c = -8, so the equation becomes

x = (-(-3) ±√((-3)² - 4(4)(-8)))/2(4).

Simplifying, we get x = (3 ±√(9 + 128))/8.

Finally, solving for x yields x = (3 ±√137)/8.

Therefore, the solution to the equation is

x = (3 ±√137)/8.

To prove the statement by contradiction, we assume that option C) The average of three real numbers is less than at least one of the numbers is true.

Then, we can use a counterexample to disprove this assumption.
For example, let's consider the numbers 1, 2, and 3.
Their average is (1+2+3)/3 = 2, which is greater than all of the numbers.
This counterexample shows that the assumption is false, and therefore, option C) is not correct.
Hence, the correct assumption to prove the statement by contradiction is option A) The average of three real numbers is greater than or equal to at least one of the numbers.

\(\frac{6}{8}\) is a fraction that is equivalent to three fourth, or \(\frac{3}{4}\). The numerator and denominator are changed by multiplying and dividing the original fraction by the same natural number as 2.

According to equivalent fractions, two or more fractions are considered to be equal if both provide the same fraction followed by simplification. An element of a whole is a fraction. The same amount of the whole is represented by equivalent fractions. An equivalent fraction can be obtained by multiplying and dividing the same natural number with the given fraction. As of the query, \(\frac{3}{4}\) is an improper fraction, whose equivalent fractions can be obtained as follows:

Multiplying natural numbers lie 2, 3, 4... with the given fraction:

\(\frac{3}{4}\) × \(\frac{2}{2}\) = \(\frac{6}{8}\)

Hence, 6/8 is an equivalent fraction of 3/4. Other than this, we can also obtain more equivalent fractions in the same manner.

\(\frac{3}{4}\) × \(\frac{3}{3}\) = \(\frac{9}{12}\)

Hence, 9/12 is also equivalent to 3/4 when reduced to lowest terms. Similarly, we can find that 12/16, 15/20, and 18/24 are also equivalent fractions of 3/4.
