A new Youth Activity Center is being built in Hadleyville. The perimeter of the rectangular playing field is 430 yards. The length of the field is 5 yards less than quadruple the width. What are the dimensions of the

playing field?

The width is yards.

The length is yards.

Answers

Answer:

Width = 44 yards

Length = 171 yards

Step-by-step explanation:

Given:

Perimeter of the rectangular field = 430 yards.

Let:

The length of the field be L

The width of the field be W.

From the question:

The length of the field is 5yards less than quadruple the width. This implies that;

L = 4W - 5

But.

Perimeter (P) of a rectangle is given by:

P = 2(L + W)       ---------------(i)

Substitute the values of P = 430, L = 4W - 5 and W into equation (i) as follows;

430 = 2(4W - 5 + W)

430 = 2(5W - 5)

430 = 10W - 10

10W = 430 + 10

10W = 440

Divide both sides by 10

W = 44

Therefore, the width of the field is 44 yards.

Remember that,

L = 4W - 5          

[Now substitute W = 44]

L = 4(44) - 5

L = 176 - 5

L = 171

Therefore, the length of the field is 171 yards

Find his average speed in meters per second.

Answers

Average speed of Usain Bolt is 10.41 m/s.

What is Speed?

The distance travelled by an object in relation to the amount of time it takes to travel that distance can be used to define speed. In plainer terms, it is a gauge of how quickly an object moves.

Average speed = (Total distance travelled)/(Total time required)

SI unit of speed is m/s.

Distance Travelled by Usain Bolt = 100m

Time required to travel this distance =  \(9\frac{3}{5}\) = 48 ⁄ (5 sec)

Average speed = (Total distance travelled)/ (Total time required)

Average speed = 100/ (48/5)

                          = 500/48

                          = 10.41 m/s

Therefore, average speed of Usain Bolt is 10.41 m/s.

What is the factorial?

Factorial is an important function, which is used to find how many ways things can be arranged or the ordered set of numbers.The factorial of a whole number is the function that multiplies the number by  number below it.

The number of ways to shuffle a deck of cards is astronomically large, far greater than the estimated number of atoms in the observable universe.

A standard deck of 52 playing cards can be arranged in 52 factorial ways, denoted as 52!. This means multiplying all the positive integers from 1 to 52 together:

52! = 52 × 51 × 50 × ... × 3 × 2 × 1=8.0658 × \(10^{67}\).

Assume that when adults with smartphones are randomly selected, 36% use them in meetings or classes. If 8 adult smartphone users are randomly selected, find the probability that exacty 6 of them use their smartphones in meetings or classes.
The probability is ___

Answers

The probability of exactly 6 out of 8 randomly selected adult smartphone users using their smartphones in meetings or classes can be calculated using the binomial probability formula.

The probability of an adult smartphone user using their smartphone in meetings or classes is given as 36% or 0.36. Let's denote this probability as p.

The number of trials is 8 (since we are selecting 8 adult smartphone users).

To find the probability of exactly 6 out of 8 using their smartphones in meetings or classes, we use the binomial probability formula:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k),

where P(X = k) is the probability of getting exactly k successes, n is the number of trials, p is the probability of success, and C(n, k) is the number of combinations.

In this case, we want to find P(X = 6), so we substitute k = 6, n = 8, and p = 0.36 into the formula:

P(X = 6) = C(8, 6) * (0.36)^6 * (1 - 0.36)^(8 - 6).

Calculating the values:

C(8, 6) = 8! / (6! * (8 - 6)!) = 28.

P(X = 6) = 28 * (0.36)^6 * (0.64)^2.

Now, we can calculate the probability:

P(X = 6) ≈ 0.2173.

Therefore, the probability that exactly 6 out of 8 randomly selected adult smartphone users use their smartphones in meetings or classes is approximately 0.2173.

lim x approaches infinity (2x-1)(3-x)/(x-1)(x+3) is

Answers

The limit of (2x-1)(3-x)/(x-1)(x+3) as x approaches infinity is 0.

To find the limit of the function (2x-1)(3-x)/(x-1)(x+3) as x approaches infinity, we will divide both the numerator and denominator through the highest power of x. In this case, the highest power of x is x², so we can divide both the numerator & the denominator through x²:

\([(2x-1)/(x^2)] * [(3-x)/((x-1)/(x^2)(x+3))]\)

Now, as x approaches infinity, every of the fractions within the expression procedures zero except for (2x-1)/(x²). This fraction techniques 0 as x procedures infinity because the denominator grows quicker than the numerator. therefore, the limit of the expression as x strategies infinity is:

0 * 0 = 0

Consequently, When x gets closer to infinity, the limit of (2x-1)(3-x)/(x-1)(x+3) is 0.

What is translation?

In mathematics, a translation moves a shape left, right, up, or down but does not turn it. The translated (or picture) shapes appear to be the same size as the original shape, showing that they are congruent. They've just moved in one or more directions.

Given that a point at (−3,−2) is transformed in two steps. It is reflected in y = x. It is translated as 3 units right and 2 units up.

The translated point will be,

(−3,−2) ⇒ (-3,2)

if lisa's score was 86 and that score was the 23rd score from the top in a class of 280 scores, what is lisa's percentile rank?

Answers

Lisa's percentile rank is approximately 7.857%.

To calculate Lisa's percentile rank, you can use the formula:

Percentile Rank = (Number of scores less than Lisa's score / Total number of scores) * 100

In this case, Lisa's score is 86, and it is the 23rd score from the top in a class of 280 scores. Therefore, the number of scores less than Lisa's score is 23 - 1 = 22 (excluding Lisa's score itself).

Substituting the values into the formula:

Percentile Rank = (22 / 280) * 100 ≈ 7.857%

Lisa's percentile rank is approximately 7.857%.

Suppose $726.56 is deposited at the end of every six months into an account earning 6.45% compounded semi-annually. If the balance in the account four years after the last deposit is to be $31 300.00, how many deposits are needed? (This question asks for 'n')

Answers

We need approximately 10 deposits to reach a balance of $31,300 four years after the last deposit which is compounded semi-annually.

To solve this problem, we can use the formula for the future value of an annuity:

\(FV = P * ((1 + r)^n - 1) / r\)

Where:

FV is the future value of the annuity

P is the periodic payment or deposit amount

r is the interest rate per period

n is the number of periods

In this case, the deposit amount is $726.56, the interest rate is 6.45% compounded semi-annually, and the future value is $31,300. We need to find the number of deposits (n).

We can rearrange the formula and solve for n:

n = log((FV * r) / (P * r + FV)) / log(1 + r)

Substituting the given values:

n = log((31,300 * 0.03225) / (726.56 * 0.03225 + 31,300)) / log(1 + 0.03225)

Using a calculator or software, we find that n ≈ 9.989.

Therefore, we need approximately 10 deposits to reach a balance of $31,300 four years after the last deposit.

(b.) the highest 5% of the hourly wages are greater than what amount?

Answers

Using the standard normal distribution, we find that approximately 73.8% of workers receive wages between $4.75 and $5.69 per hour. Using the inverse of the standard normal distribution, we find that the highest 5% of hourly wages are greater than approximately $6.09.

Using a standard normal distribution table or calculator with a mean of 5.25 and a standard deviation of 0.60, we can find that approximately 79.42% of workers receive wages between $4.75 and $5.69 per hour.

Using a standard normal distribution table or calculator, we can find the z-score corresponding to the highest 5% of wages, which is approximately 1.645.

Then, we can solve for x in the equation z = (x - μ) / σ, where z is the z-score, μ is the mean of 5.25, and σ is the standard deviation of 0.60. This gives us x = zσ + μ, which is approximately $6.09 per hour. Therefore, the highest 5% of hourly wages are greater than $6.09 per hour.

The maximum value of z is 0, and the values of the decision variables are x1 = 0, x2 = 10, x3 = 0, x4 = 0.

maximize: z = c1x1 + c2x2 + ... + cnxn

subject to

a11x1 + a12x2 + ... + a1nxn ≤ b1

a21x1 + a22x2 + ... + a2nxn ≤ b2

am1x1 + am2x2 + ... + amnxn ≤ bmxi ≥ 0 for all i

In our case,

the given LP is:maximize: z = 36x1 + 30x2 - 3x3 - 4x

subject to:

x1 + x2 - x3 ≤ 5

6x1 + 5x2 - x4 ≤ 10

xi ≥ 0 for all i

We can rewrite the constraints as follows:

x1 + x2 - x3 + x5 = 5  (adding slack variable x5)

6x1 + 5x2 - x4 + x6 = 10  (adding slack variable x6)

Now, we introduce the non-negative variables x7, x8, x9, and x10 for the four decision variables:

x1 = x7

x2 = x8

x3 = x9

x4 = x10

The objective function becomes:

z = 36x7 + 30x8 - 3x9 - 4x10

Now we have the problem in standard form as:

maximize: z = 36x7 + 30x8 - 3x9 - 4x10

subject to:

x7 + x8 - x9 + x5 = 5

6x7 + 5x8 - x10 + x6 = 10

xi ≥ 0 for all i

To apply the simplex algorithm, we initialize the simplex tableau as follows:

  |  Cj   |   x5   |   x6   |   x7   |   x8   |   x9   |   x10  |    RHS  |

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

z |  0    |   0    |   0    |  36    |   30   |   -3   |   -4   |    0    |

x5|   0   |   1    |   0    |   1    |   1    |   -1   |   0    |    5    |

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

x6|   0   |   0    |   1    |   6    |   5    |   0    |   -1   |   10    |

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

Now, we can proceed with the simplex algorithm to find the optimal solution. I'll perform the iterations step by step:

Iteration 1:

1. Choose the most negative coefficient in the 'z' row, which is -4.

2. Choose the pivot column as 'x10' (corresponding to the most negative coefficient).

3. Calculate the ratios (RHS / pivot column coefficient) to find the pivot row. We select the row with the smallest non-negative ratio.

Ratios: 5/0 = undefined, 10/(-4) = -2.5

4. Pivot at the intersection of the pivot row and column. Divide the pivot row by the pivot element to make the pivot element 1.

5. Perform row operations to

make all other elements in the pivot column zero.

After performing these steps, we get the updated simplex tableau:

  |  Cj   |   x5   |   x6   |   x7   |   x8   |   x9   |   x10  |    RHS  |

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

x10|   0  |   0    |   0.2  |   1.2  |   1   |   0    |   1    |   2.5   |

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

Iteration 2:

1. Choose the most negative coefficient in the 'z' row, which is -3.

2. Choose the pivot column as 'x9' (corresponding to the most negative coefficient).

3. Calculate the ratios (RHS / pivot column coefficient) to find the pivot row. We select the row with the smallest non-negative ratio.

Ratios: 12/(-3) = -4, 5/(-0.2) = -25, 2.5/0.2 = 12.5

4. Pivot at the intersection of the pivot row and column. Divide the pivot row by the pivot element to make the pivot element 1.

5. Perform row operations to make all other elements in the pivot column zero.

After performing these steps, we get the updated simplex tableau:

  |  Cj   |   x5   |   x6   |   x7   |   x8   |   x9   |   x10  |    RHS  |

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

z |  0    |   0    |  0.8   |  34    |   30   |   0    |   4    |   0     |

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

x5|   0   |   1    |  -0.4  |   0.6  |   1    |   5   |   -2   |   10    |

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

x9|   0   |   0    |   1    |   6    |   5    |   0   |   -5   |   12.5  |

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

Iteration 3:

No negative coefficients in the 'z' row, so the optimal solution has been reached.The optimal solution is:

z = 0

x1 = x7 = 0

x2 = x8 = 10

x3 = x9 = 0

x4 = x10 = 0

x5 = 10

x6 = 0

Therefore, the maximum value of z is 0, and the values of the decision variables are x1 = 0, x2 = 10, x3 = 0, x4 = 0.

Answers

If C and D are square matrices of size m X m, then Option (C) (2) det(D. Dt) = (det(D))² is the statement that is not true.

The given options pertain to properties of determinants involving square matrices C and D of size m × m. Let's evaluate each option to identify the statement that is not true.

Option (1) states that det(C.D) = det(C) · det(D). This is indeed true. The determinant of a product of matrices is equal to the product of their determinants. Therefore, option (1) is a valid property of determinants.

Option (2) claims that det(D.Dt) = (det(D))². However, this is not correct. The correct property is det(D.Dt) = (det(D))^(m), where m represents the size of the square matrix D. Taking the determinant of the transpose of D does not result in squaring the determinant, but rather raising it to the power of the matrix's dimension.

Option (3) states that det(AdjD) = (det(D))^(m-1). This statement is true. A matrix's adjugate (or adjoint) is obtained by taking the transpose of the cofactor matrix. The determinant of the adjugate matrix is equal to the determinant of the original matrix raised to the power of m-1, where m represents the size of the square matrix D.

Option (4) suggests that det(5C + 4D) = 5det(C) + 4det(D). This is a correct statement. The determinant of a scaled sum of matrices can be computed by scaling the individual determinants. Therefore, the determinant of 5C + 4D is equal to 5 times the determinant of C plus 4 times the determinant of D.

Option (5) claims that det(C^(-1)) = 1/det(C). This statement is also true. The determinant of the inverse of a matrix is the reciprocal of the determinant of the original matrix. In other words, if C^(-1) is the inverse of matrix C, then det(C^(-1)) = 1/det(C).

In summary, the statement that is not true among the given options is option (2) det(D.Dt) = (det(D))². The correct property is det(D.Dt) = (det(D))^(m), where m represents the size of the square matrix D.
