It is not possible to construct a triangle whose sides are 5cm ,5cm and 10cm , because the sum of two sides is not greater then third side .

For any three sides to form a triangle , it should satisfy the condition that , the sum of any two sides should must be greater than the third side .

We apply this condition on the given sides ,

we get ;

the sides of the triangle are  ⇒ 5cm ,5cm and 10cm ;

the sum of sides : 5 + 5 = 10 which is not greater than the third side (10cm) ;

these sides do not satisfy the condition ,

Therefore , the condition to form the triangle is not satisfied , so the triangle cannot be constructed .

The probability of not getting a 4 is 0.75.

Given is a spinner spins with having fours numbers on it,

We need to find the probability of not having a 4,

So, the probability of not event = 1-P(E)

Also the list of outcomes = 1, 2, 3, 4

Therefore, here,

The probability of getting 4 = 1/4 = 0.25

Therefore the probability of not getting a 4 = 1-1/4 = 3/4 = 0.75

Hence the probability of not getting a 4 is 0.75.

According to using the arithmetic operations the total yards of metal is needed =  4(1/4).

The study and application of numbers in all other branches of mathematics is the focus of the branch of mathematics known as arithmetic operations. In essence, it consists of addition, subtraction, multiplication, and division operations.

There are several laws that control the order in which you do operations in math and algebra. The three that receive the most focus are the distributive, associative, and commutative laws. Over time, people have come to realize that the order of the numbers is irrelevant when adding or multiplying.

First pieces of metal =  1 *(1/6)

                                  = 7/6

Second pieces of metal = 3/12

Adding both the pieces :

=7/6 + 3/12

= (14 + 3)12

= 17/12.

now,

multiply that by 3.

We get:

The producer surplus is: Producer surplus = Total revenue - Total variable cost= 57000 - 24000= $33000. Therefore, the producers' surplus is $33,000 (rounded to the nearest dollar).

The producers' surplus can be calculated using the formula given below:

Producer surplus = Total revenue - Total variable cost

The given price of Blu-ray players in the market is given by, p = 100(0.9x + 0.3 / 1+x) dollars.

If the selling price is $190/unit, then we can write:

190 = 100(0.9x + 0.3 / 1+x)

Simplifying the above equation, we get: 1.9 = 0.9x + 0.3 / 1+x

Solving the above equation for x:1.9(1+x) = 0.9x + 0.3

After solving, x = 0.3 (rounded off to nearest thousand)

Thus, the manufacturer will make 300 units available in the market per week.

The total revenue generated by the producer is given by:

Total revenue = selling price × quantity= 190 × 300 = $57000

Total variable cost is the cost of producing these units, which is equal to the amount spent on raw materials, labor costs, and other variable expenses incurred by the producer.

Let's assume that the variable cost is equal to $80/unit.

Hence, the total variable cost of producing 300 units is given by:

Total variable cost = variable cost × quantity= 80 × 300 = $24000

Therefore, the producer surplus is: Producer surplus = Total revenue - Total variable cost= 57000 - 24000= $33000Therefore, the producers' surplus is $33,000 (rounded to the nearest dollar).

A combinatorial proof of Pascal's identity states that for positive integers n and k (with n ≥ k), the binomial coefficient c(n, k) can be expressed as the product of c(n, k – 1) and c(n – 1, k – 1). This can be proven by considering a group of n + 1 elements, where one element is chosen as a special element. By counting the number of subsets based on whether or not the special element is included, the identity can be derived.

To prove Pascal's identity using a combinatorial approach, we consider a set of n + 1 elements and designate one element as the "special" element. Let's denote this special element as E.

We start by counting the number of subsets of this set of n + 1 elements in two different ways.

First, let's count the subsets that contain k elements. There are c(n, k) such subsets, as we choose k elements from the remaining n elements (excluding the special element).

Now, let's count the subsets based on whether or not the special element E is included.

If E is included, we have k – 1 remaining elements to choose from the remaining n elements (excluding E). Hence, the number of subsets with E included is c(n, k – 1).

If E is not included, we can choose k elements from the remaining n elements (again, excluding E). Therefore, the number of subsets without E is c(n – 1, k).

Since the total number of subsets is the same regardless of whether E is included or not, we can equate the two counts:

c(n, k) = c(n, k – 1) + c(n – 1, k).

This equation is precisely Pascal's identity. Hence, we have proven the identity combinatorially.

The number of voters that should be sampled for a confidence interval depends on the desired level of confidence and the margin of error.

A larger sample size generally leads to a smaller margin of error and a higher level of confidence in the accuracy of the results. However, the relationship between sample size and margin of error is not linear, meaning that doubling the sample size will not necessarily halve the margin of error.
To calculate the required sample size, a formula can be used that takes into account the margin of error, level of confidence, and population size.
the number of voters that should be sampled for a confidence interval depends on several factors and cannot be determined without more information.
To determine the required sample size, you can use the following formula:
n = (Z^2 * p * (1-p)) / E^2

Where:
- n is the sample size
- Z is the Z-score (usually 1.96 for a 95% confidence interval)
- p is the estimated proportion of the population (usually 0.5 for the worst-case scenario)
- E is the margin of error (in decimal form)

Hence, without the specific margin of error, we cannot provide the exact sample size needed.

bcx + acy + abz = abc is another form of the equation of the plane with x-intercept a, y-intercept b, and z-intercept c.

What is the equivalent expression?

Equivalent expressions are expressions that perform the same function despite their appearance. If two algebraic expressions are equivalent, they have the same value when we use the same variable value.

bcx + acy + abz = abc is another form of the equation of the plane with x-intercept a, y-intercept b, and z-intercept c.

To find an equation of the plane with x-intercept a, y-intercept b, and z-intercept c, we can use the intercept form of the equation of a plane:

x/a + y/b + z/c = 1

This equation states that any point (x, y, z) on the plane will satisfy this equation.

To see why this is true, note that if x = a, then the left-hand side of the equation is 1, since y/b + z/c = 0 (since the numerator is 0).

Similarly, if y = b, then the left-hand side of the equation is 1, since x/a + z/c = 0.

Finally, if z = c, then the left-hand side of the equation is 1, since x/a + y/b = 0.

To simplify this equation, we can multiply both sides by the denominators a, b, and c:

hence, bcx + acy + abz = abc is another form of the equation of the plane with x-intercept a, y-intercept b, and z-intercept c.

The first expression  X (Y + Z) = X.Y + X.Z is distributive property of multiplication and the second expression X(Y.Z) = (X.Y)Z = X.Y.Z is associative property of multiplication.

According to the question,

We have the following two expressions:

X (Y + Z) = X.Y + X.Z

X(Y.Z) = (X.Y)Z = X.Y.Z

Now, the distributive property of multiplication states that the number outside the bracket is multiplied into each number within the bracket and the sign remains the same.

For example, 2(5+7) is 2*5+2*7.

The associative property of multiplication states that the result of the multiplication of numbers is same even when the bracket is changed from one number to another.

Hence, the first expression  X (Y + Z) = X.Y + X.Z is distributive property of multiplication and the second expression X(Y.Z) = (X.Y)Z = X.Y.Z is associative property of multiplication.

Boolean Algebra:

Basically, Boolean algebra is a branch of mathematics that deals with operations on logical values with binary variables.

And there are three properties in Boolean algebra.

They are, Commutative, associative, and distributive properties.

Given,

Sam’s teacher wrote two Boolean expressions on the whiteboard. Identify the names of the laws of these expressions.

Expression 1: X (Y + Z) = X.Y + X.Z

Expression 2: X(Y.Z) = (X.Y)Z = X.Y.Z

Here we need to find the name of the property used by the teacher on those two expression.

While we looking into the question,

We have the give the two expressions:

They are

=> X (Y + Z) = X.Y + X.Z

=> X(Y.Z) = (X.Y)Z = X.Y.Z

When we take the first expression,

X (Y + Z) = X.Y + X.Z

That states that the distributive property of multiplication is used here and the process of the distribution property is the number outside the bracket is multiplied into each number within the bracket and the sign remains the same.

Similarly, when we take the second expression

X(Y.Z) = (X.Y)Z = X.Y.Z

That uses the associative property of multiplication which is the result of the multiplication of numbers is same even when the bracket is changed from one number to another.

Therefore, the first expression  X (Y + Z) = X.Y + X.Z uses the distributive property of multiplication and the second expression X(Y.Z) = (X.Y)Z = X.Y.Z uses the associative property of multiplication.

The Gap for TestBank is $200 million. If interest rates decline by 2%, the change in bank profits can be calculated based on the Gap and the rate-sensitive assets and liabilities.

The Gap is a measure of the difference between rate-sensitive assets and rate-sensitive liabilities for a bank. In this case, TestBank has rate-sensitive assets of $400 million and rate-sensitive liabilities of $200 million. To calculate the Gap, we subtract the rate-sensitive liabilities from the rate-sensitive assets:

Gap = Rate-sensitive assets - Rate-sensitive liabilities

    = $400 million - $200 million

    = $200 million

This means that TestBank has a Gap of $200 million.

When interest rates decline by 2%, it generally leads to an increase in the value of rate-sensitive assets and a decrease in the value of rate-sensitive liabilities. As a result, TestBank's rate-sensitive assets would increase in value, while its rate-sensitive liabilities would decrease in value.

The change in bank profits can be estimated by multiplying the Gap by the change in interest rates. In this case, the change in interest rates is a decline of 2%. Therefore, the change in bank profits would be:

Change in bank profits = Gap * Change in interest rates

                            = $200 million * (-2%)

                            = -$4 million

Hence, if interest rates decline by 2%, TestBank's profits would decrease by $4 million.
