Step-by-step explanation:

The number of possible ways you can distribute the balls among the three boxes so that each box contains at least one ball = 21

Here we have 3 empty boxes.

Let us assume that a, b and c be these empty boxes.

and the total number of balls = 8

We need to distribute the balls among the three boxes so that each box contains at least one ball.

This means that a + b + c = 8

By allotting 1 ball to each box so that no box remains empty.

We get an equation a + b + c = 5

So, the possible number of ways to by allotting 1 ball to each box so that no box remains empty would be:

⁷C₂

Using combination formula:

⁷C₂

= 7! / 2!(7 - 2)!

= 21

Therefore,  the required number of ways = 21

The distance Terry needs to run when the winner crosses the finish line is 1. 6 miles.

The race was a 10 km race and she has completed 74% of the race when the winner crosses the finish line.

Therefore, the number of more miles Terry need to cover can be calculated as follows:

74 / 100 × 10 = 740  / 100  = 7.4 km

He has covered 7.4 km.

The distance remaining to cover = 10 km - 7.4 km = 2.6 km

Therefore,

4km  = 2.48 miles

2.6 km = ?

cross multiply

The distance remaining to cover(miles) = 2.6 × 2.48 / 4

The distance remaining to cover(miles) = 6.448 / 4

The distance remaining to cover(miles) = 1.612

The distance remaining to cover(miles) = 1.6 miles

The soccer team sold 25 pizzas.

Let x be the number of pizzas sold. Then, the number of subs sold would be x + 11.

The total amount of money earned from pizzas is $5.00 * x and the total amount of money earned from subs is $3.00 * (x + 11).

We can represent this situation using the following system of equations:

5x + 3(x + 11) = 233

Expanding the second equation:

5x + 3x + 33 = 233

Combining like terms:

8x + 33 = 233

Subtracting 33 from both sides:

8x = 200

Dividing both sides by 8:

x = 25

So, the soccer team sold 25 pizzas.

The correct option is A, equilibrium price increases from $6 to $8.

In economics, equilibrium is a state in which the supply and demand for a product or service are balanced, resulting in a stable price. This can occur in a free market, where the price of a good or service is determined by the interaction of buyers and sellers.

Overall, equilibrium is a fundamental concept in many different fields, representing a state of balance or stability in a system or situation.

If the demand schedule changes from D2 to D1, then the demand curve shifts to the left. As a result, the new equilibrium point will be where the new demand curve (D1) intersects with the supply curve (S1).

From the table, we can see that the new equilibrium point is at a price of $8 and a quantity of 15. Therefore, the equilibrium price increases from $6 to $8, but the equilibrium quantity decreases from 15 to 13.

So the correct answer is: equilibrium price increases from $6 to $8.

The fact that two people taking the same test in two different places will receive the same instructions, the same questions, and the same time limits means that the test has been standardized.

Standardized tests are designed to have a uniform format, including consistent instructions, the same questions, and equal time limits to ensure that the scores are reliable, valid, and consistent across different test-takers and testing locations. The standardized testing system enables educators to assess a student's academic performance in a specific subject and to compare students' knowledge and skills. Therefore, it is easier for teachers to compare students' results to decide which students have achieved the desired level of academic performance and those who need additional support or interventions. Standardized tests play a critical role in determining a student's academic progress, educational opportunities, and career prospects. Standardized tests can be used to identify students' strengths and weaknesses, provide information about how students are learning, and to evaluate the effectiveness of educational programs.

To decide which measurement has a reverse relationship with the number of wins, we ought to seek for a relationship coefficient with negative esteem. A negative correlation coefficient shows that as one variable increments, the other variable tends to diminish.

Without seeing the real relationship framework, we cannot point out the precise statistic that has a reverse relationship with the number of wins. In any case, ready to search for the relationship coefficient that features negative esteem.

For illustration, in the event that we have a relationship network like this:

markdown

| W | Period | WHIP | SO/9 | BB/9 |

----------------------------------------------

W | 1 | -0.7 | -0.6 | 0.5 | -0.3 |

----------------------------------------------

Period | -0.7| 1 | 0.9 | -0.8 | 0.5 |

----------------------------------------------

WHIP | -0.6| 0.9 | 1 | -0.7 | 0.4 |

SO/9 | 0.5| -0.8 | -0.7 | 1 | -0.4 |

----------------------------------------------

BB/9 | -0.3| 0.5 | 0.4 | -0.4 | 1 |

----------------------------------------------

We are able to see that the relationship coefficient between the number of wins (W) and the earned run normal (Time) is -0.7, which indicates a strong negative relationship. This implies that as the Time increments (showing poorer pitching execution), the number of wins tends to diminish. Subsequently, Time has a reverse relationship with the number of wins.

                                                     x/side 3 = 5 / 3

                                                     x  = (5/3) side 3

                                                     x (3/5)  = side 3

                                                     perimeter = 65    slove for x

          65  = x + x + 3x/5

          side 3 = 25(3/5)  = 15

The result of subtracting the sum of (-250) and (-130) from the sum of 236 and (-470) is -146.

To calculate the given expression, we start by finding the sum of 236 and (-470). Adding these two numbers, we get 236 + (-470) = -234. Next, we find the sum of (-250) and (-130). Adding these two numbers, we get (-250) + (-130) = -380. Finally, we subtract the sum of (-250) and (-130) from the sum of 236 and (-470):

(-234) - (-380) = -234 + 380 = 146

However, the negative sign is retained because the subtraction involves subtracting a larger negative number from a smaller negative number. Therefore, the result of subtracting the sum of (-250) and (-130) from the sum of 236 and (-470) is -146.

Answer:

B. 85.6%

Step-by-step explanation:

Since we want to find the percentage, which is essentially a fraction, we will divide the area of the smaller frame by the area of the larger paper.

The paper and frame are both rectangles, so the area of a rectangle is denoted by A = lw, where l is the length and w is the width.

For the paper, the length is l = 8.5 and the width is w = 11. So:

A = lw

A = 8.5 * 11 = 93.5 inches squared

For the frame, the length is l = 8 and the width is w = 10. So:

A = lw

A = 8 * 10 = 80 inches squared

The percentage of the original sketch included in the frame would be:

(80 / 93.5) * 100 ≈ 85.6%

The answer is thus B.

The polynomial function whose graph could be the one shown in the image is f(x) = x³ - x² - 25x - 25

What is the polynomial function?

A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc. For example, 2x+5 is a polynomial that has an exponent equal to 1.

The polynomial function whose graph could be the one shown in the image is:

f(x) = x³ - x² - 25x - 25

We can see that the graph has a local maximum at x ≈ -3, a local minimum at x ≈ 1, and a point of inflection at x ≈ -1. These features match with the graph of f(x) = x³ - x² - 25x - 25.

Let's take a look at the other options and see why they are not correct:

f(x) = x³ + x² - 25x - 25: This function has a local minimum at x ≈ -3, which does not match with the graph shown.

f(x) = x³ + x² + 25x + 25: This function has a positive leading coefficient, which means that it has a positive end behavior. However, the graph shown has a negative end behavior, so this cannot be the correct function.

f(x) = x³ - x² + 25x + 25: This function has a local maximum at x ≈ -1, which is the location of the point of inflection in the graph shown. However, it does not have a local minimum at x ≈ 1, so this cannot be the correct function.

Hence, The polynomial function whose graph could be the one shown in the image is f(x) = x³ - x² - 25x - 25

The largest positive integer $n$ for which the given equation holds true for all real numbers $a_1, a_2, \dots, a_{n-1}$ (where $a_{n-1} \neq 0$) is $n = 3$.

We are given the equation $a_{n-1}x^2 - 2x\sqrt{a_1^2a_2^2\dots a_{n-1}^2}(a_1a_2\dots a_{n-1}) = 0$, and we want to determine the largest $n$ for which this equation holds true for any choice of $a_1, a_2, \dots, a_{n-1}$.

If we simplify the equation, we can rewrite it as $x^2 - 2x\left|a_1a_2\dots a_{n-1}\right| = 0$. From this equation, we can observe for any non-zero value of $a_1a_2\dots a_{n-1}$, the equation will always hold true, regardless of the value of $x$. However, when $a_1a_2\dots a_{n-1} = 0$, the equation becomes $x^2 = 0$, which implies that $x = 0$.

Therefore, for $n > 3$, we can find values of $a_1, a_2, \dots, a_{n-1}$ for which the equation does not hold true, making $n = 3$ the largest positive integer for which the equation holds true for all $a_1, a_2, \dots, a_{n-1}$.
