Answer:

$6,232.89 or $6,232.90

Step-by-step explanation:

A=P(1+(r/n))^nt

A= 3,232.89

3,232.89+3000= 6,232.89

The perimeter of the new TV will be 179.77 inches.

From the information, the TV was 32 inches (across the diagonal) and had a perimeter of 87.16 inches and the new TV is 66 inches across the diagonal.

It should be noted that the perimeter simply means the total length of the boundary of the object. This will be calculated thus:

= (66 × 87.16) / 32

= 5752.56 / 32

= 179.77 inches.

In conclusion, the perimeter is 179.77 inches.

The amount of fabric used on the headband and wristband for each player is 27.64 inches.

The operations that we use in particular actions like adding and taking away things or adding multiple times, diving things, etc.

The four basic Mathematical operations are addition, subtraction, multiplication, and division.

Here in this problem, we use divisions to solve the problem,

Given that,

Nancy uses 866.18 inches of fabric on headbands for 43 players and 3 coaches. 378.83 inches of fabric used on wristbands for the players only.

Number of headbands made with 866.18 inches

= 43 (player's) + 3 (coach's)  

= 46 headbands

The amount of fabric used for 1 head band = (866.18)/46 = 18.83 in

378.83 inches of fabric used on wristbands for the players only.  

The amount of fabric used for each wristband = 378.83/43 = 8.81 in

Amount of fabric used on headband and wristband = 18.83 + 8.81

= 27.64 inches

Therefore,

The amount of fabric used on the headband and wristband for each player is 27.64 inches.

Suppose we select two distinct balls

Then we have the following possibilities of selecting two balls

(2,5), (2,5), (5,2), (5,2), i.e. 4 ways to get a sum of 7...............(5+2 = 7 and 2+5 = 7)    

(2,6), (2,6), (2,6), (2,6), i.e. 4 ways to get a sum of 8...............(2+6 = 8 and 6+2 = 8)    

(6,5), (5,6) , i.e. 2 ways to get a sum of 11...............(5+6 = 11 and 6+5 = 11)    

total number of possible outcomes =  2(for a sum of 4) + 4(for a sum of 7) + 4(for a sum of 8) + 2 (for a sum of 11)

= 2 + 4 + 4+2

= 12

So, P(getting a sum of 4) = (number of ways to get a sum of 4)/total number = 2/12

similarly,

P(getting a sum of 7) = (number of ways to get a sum of 7)/total number = 4/12

P(getting a sum of 8) = (number of ways to get a sum of 8)/total number = 4/12

P(getting a sum of 11) = (number of ways to get a sum of 11)/total number = 2/12

We know that expected value E[x] = sum of all individual sum values by their respective probability

= 4*(2/12) +7*(4/12) +8*(4/12) +11*(2/12)

Let's calculate the 5% increase in the budget.

5% of 81000 =

5 / 100 = x / 81000

0.05 = x / 81000

x = 81000 * 0.05

x = 4050

No, the biconditional statement isn't true because It's not necessary that if a polygon has four sides, then It will be a square.

What is Biconditional statement?

A statement that combines a conditional statement with its opposite is known as a biconditional statement. So, if and only if the other conditional is also true, the first conditional is true.

Let's elaborate the statement, “If a polygon is a square, then it has four sides.”

We know that a square has four equal sides and So, if a polygon is a square, it must have four equal sides which states that the given statement is true.

But, if we see its converse, "If a polygon has four sides, then it is a square". It is not necessary that the polygon will be a square.

eg. A parallelogram and  rectangle also have four sides, So it could either be a parallelogram, rectangle or a square.

f(-4) = -18, f(-2) = -10, f(6) = 12 and f(-1) = -6 using the piecewise function.

A function defined by numerous sub-functions, where each sub-function applies to a distinct interval in the domain, is known in mathematics as a piecewise-defined function (also known as a piecewise function, a hybrid function, or definition by cases).  Instead of being a property of the function itself, piecewise definition is a means to express the function.

When the domain may be divided into intervals on which the property holds, the phrase "property holding piecewise for a function" is used, which is separate but related. This is a characteristic of the function itself, as opposed to the idea mentioned above.

f(-4) = 4(-4)-2 = -18  ∵-4≤-1

f(-2) = 4(-2)-2= -10  ∵-2≤-1

f(6) = [tex]\frac{1}{2}*6 + 9 = 12[/tex] ∵6>-1

f(-1) = 4(-1)-2 = -6 ∵-1≤-1

“6 more than twice m” can be written in the mathematical form as 2m+6.

The question is saying that we have to write “6 more than twice m” as an algebraic expression or into a mathematical expression.

As in the question, it is mentioned that we have to take the number m as a variable.

So, we are going to use this ‘m’ for solving this question.

Let the number be m.

Then, twice of m will be similar to 2 times m or m multiplied by 2.

Therefore, twice m will be 2m.

Now, the question is saying that 6 more than twice m.

“6 more than” means 6 is added to that specific number.

Hence, 6 more than that number which is twice of m will be 2m+6.

The correct answer is e) approximately normal with a mean 122 and standard deviation 0.35.

In this case, the distribution of the sample mean of IQ scores will be approximately normal because the sample size of 200 is sufficiently large. This is known as the Central Limit Theorem, which states that the distribution of the sample mean will be approximately normal as long as the sample size is large enough, regardless of the shape of the distribution of the population.

The mean of the sample mean distribution will be 122, which is the same as the mean of the population.

The  polynomial function that could be represented by the graph is; f(x) = x³ + x² - 6x

Let us find the zeros of the polynomial from the graph. The zeros of the polynomial will be the points where the graph crosses the x-axis.

Thus, we see that the graph crosses the x-axis at x = -3, 0 and 2. Thus, the factors of the polynomial are;

(x - 0), (x + 3) and (x - 2)

Therefore, the equation of the polynomial is;

f(x) = x(x - 2)(x + 3)

Expanding this gives us;

f(x) = x(x² + x - 6)

f(x) = x³ + x² - 6x
