Answer:

20 questions

Step-by-step explanation:

Given

\(Correct \Marks= +5\)

\(Incorrect\ Marks= -2\)

\(Score\ Obtained = 30\)

\(Number\ of\ correct\ answers = 10\)

Required

Number of questions answered

First, we need to get the total correct marks obtained by Roy

This is calculated by multiplying the correct marks by number of correct answers

\(Total = +5 * 10\)

\(Total = +50\ marks\)

Subtract this from the total scores obtained; This gives the total incorrect answer obtained by Roy

\(Incorrect = Scores\ Obtained - Total\)

\(Incorrect = 30 - (+50)\)

Open bracket

\(Incorrect = 30 - 50\)

\(Incorrect = -20\)

Divide this by -2 to get the number of incorrect answers

\(Incorrect\ Answers = \frac{-20}{-2}\)

\(Incorrect\ Answers = 10\)

Add this to the number of correct answers to give the total number of question answered

\(Total = Correct\ Answers + Incorrect\ Answers\)

\(Total = 10 + 10\)

\(Total = 20\)

Hence, Roy answered a total of 20 questions

NEED BETTER PICTURE

Step-by-step explanation:

The answer that you are looking for is b) 5(a – 2)(a – 4). In order to factor the formula, we must first locate two numbers whose sum is equal to -30 and whose product is equal to 40. Both constraints are met by the values -4 and -10, and as a result, we are able to factor the statement as 5(a – 2)(a – 4).(option b)

The following procedures can be used by us while factoring polynomials:

Find two numbers that, when added together, give you the coefficient of the middle term, and then multiply those two values by themselves to get the constant term.

Create the expression as the product of two binomials, with each binomial having one of the two numbers discovered in step 1. Write the equation as a product of two binomials.

Eliminate any factors that are frequent.

In this particular instance, the coefficient of the intermediate term is -30, while the value of the constant term is 40. When added together, the numbers -4 and -10 equal -30, and when multiplied together, they equal 40. Therefore, the expression can be factored as 5(a minus 2)(a minus 4).

According to the question, given that

4 Americans, 3 Russians, and 5 chinses into a queue, in such a way that no nationality forms a single consecutive block

Imagine that the American block is merely an additional person to be placed among the other 8 people. After that, there are 9 "people" providing 9! arrangements. In order to organize the Americans within the block, we must then multiply by 4.

With 5 real individuals and 2 blocks, we have 7 "people" for AR, giving us 7!, multiplied by 4!3! to arrange within the blocks.

Similar to how we must position the three blocks for A∩R∩C, we must also organize the blocks themselves (3! 4! 3! 5!)

If the price of capital increases in an industry and the scale effect dominates, (c) wages and employment levels will both decrease.

The scale effect refers to the impact on employment levels resulting from changes in the size or scale of production. When the price of capital increases, it becomes relatively more expensive to employ capital-intensive methods of production. As a result, firms may scale back their capital usage and rely more on labor, leading to a decrease in employment levels.

Additionally, when the price of capital increases, firms may experience higher production costs. In response, they may reduce wages to maintain profitability. Therefore, both wages and employment levels are expected to decrease when the price of capital increases and the scale effect dominates.

The coefficient of determination (R^2) for the given regression model cannot be determined without additional information such as the sum of squares of regression and total sum of squares.

The coefficient of determination, also known as R-squared (R^2), measures the proportion of the variation in the dependent variable (weekly revenue) that is explained by the independent variable (advertising expenditures). In other words, it tells us how well the regression model fits the data.
To calculate R^2, we can use the formula:
R^2 = SSR / SST
where SSR is the sum of squares regression and SST is the total sum of squares.
From the given information, we have the following values:
SSR = 18.3457692 (sum of squares regression)
SST = 20.14015595 (total sum of squares)
Plugging these values into the formula, we can calculate R^2:
R^2 = SSR / SST
   = 18.3457692 / 20.14015595
   = 0.9107 (rounded to four decimal places)
Therefore, the coefficient of determination (R^2) for this model is 0.9107. This means that approximately 91.07% of the variation in weekly revenue can be explained by the advertising expenditures.

The number of different sets of three points of this grid can be the three vertices of an isosceles triangle is 36.

An isosceles triangle is one with two equal sides. The two angles that face the two equal sides are also equal. An isosceles triangle, in other words, is a triangle whose two sides are equal in length.

By using the Permutation formula,

Number of isosceles triangle to be formed is,

9!/(7!x2!) = 9x8x7!/7!x2!

= 9x8/2

= 36

So number of isosceles triangle that can be formed of this 3-by-3 grid is 36.

a. The expression representing the amount of canned food collected so far is 5\(x^{2}\) + 2xy + 8.

b. The expression representing the number of cans the friends still need to collect to meet their goal is \(x^{2}\) − 4xy - 5.

The solution has been obtained by using the arithmetic operations.

What are arithmetic operations?

All real numbers can be explained using the four fundamental operations, generally known as "arithmetic operations." Operations like quotient, product, sum, and difference are placed after operations like division, multiplication, addition, and subtraction in mathematics.

a. We are given that the friends have collected the following number of cans:

Jessa: 2\(x^{2}\) − 4

Tyree: 3\(x^{2}\)

Ben: 2xy + 12

So, using the addition operation, we get

⇒ 2\(x^{2}\) − 4 + 3\(x^{2}\) + 2xy + 12

⇒ 5\(x^{2}\) + 2xy + 8

So, the expression representing the amount of canned food collected so far is 5\(x^{2}\) + 2xy + 8.

b. It is given that their canned food collection goal is represented by the expression 6\(x^{2}\) − 2xy + 3.

So, using the subtraction operation, we get

⇒ 6\(x^{2}\) − 2xy + 3 - (5\(x^{2}\) + 2xy + 8)

⇒ 6\(x^{2}\) − 2xy + 3 - 5\(x^{2}\) - 2xy - 8

⇒ \(x^{2}\) − 4xy - 5

So, the expression representing the number of cans the friends still need to collect to meet their goal is \(x^{2}\) − 4xy - 5.

Hence, the required solution has been obtained.
