Supplementary angles

Answer:

x = 3

y = 23

z = 4

Step-by-step explanation:

To find the values of x, y, and z in the rhombus, we need to use the properties of a rhombus. One of the properties of a rhombus is that its opposite angles are equal. Another property is that its diagonals are perpendicular bisectors of each other.

Let's label the vertices of the rhombus as A, B, C, and D, and the midpoint of diagonal AC as M. We can use the given information to write some equations:

First, we know that diagonal AC is perpendicular to diagonal BD, so we have:

-2x + 6 = 0

Solving for x, we get:

x = 3

Next, we know that diagonal AC bisects angle ACD, so we have:

y = 46/2 = 23

Now, we can use the fact that AM is the perpendicular bisector of CD to find z. Since M is the midpoint of AC, we have:

AM = MC

Using the distance formula, we can find the lengths of AM and MC in terms of z:

AM = sqrt((2z-8)^2 + (5y-4)^2)

MC = sqrt((8-2z)^2 + (5y-4)^2)

Setting these two expressions equal to each other, we get:

sqrt((2z-8)^2 + (5y-4)^2) = sqrt((8-2z)^2 + (5y-4)^2)

Simplifying this equation, we get:

4z - 16 = 16 - 4z

8z = 32

z = 4

Therefore, the values of x, y, and z are:

x = 3

y = 23

z = 4

So, the solution is x=3, y=23, and z=4.

Answer:

x = 6.111... and y = 1.

Step-by-step explanation:

To use Cramer's Rule, we first write the system of equations in matrix form, where the coefficients of x and y are placed in a matrix, and the constant terms are placed in a separate matrix. We then calculate the determinant of the coefficient matrix, which is the number that is obtained by multiplying the diagonal elements and subtracting the product of the off-diagonal elements.

Next, we replace the first column of the coefficient matrix with the constant terms and calculate the determinant of the resulting matrix. We do the same thing for the second column of the coefficient matrix. We then use Cramer's Rule to solve for x and y, which involves dividing the determinant of the matrix obtained by replacing the column of x coefficients with the constant terms by the determinant of the coefficient matrix to get the value of x. We do the same thing to find the value of y by dividing the determinant of the matrix obtained by replacing the column of y coefficients with the constant terms by the determinant of the coefficient matrix.

In the case of the given system of equations, the determinant of the coefficient matrix is 18. We then calculate the determinants of the matrices formed by replacing the first column of the coefficient matrix with the constant terms and the second column of the coefficient matrix with the constant terms. Using these determinants, we apply Cramer's Rule to find the values of x and y, which are x = 6.111... and y = 1.

Rachel $8500 invested at 4% and $8800 invested at 2% interest rate.

Investment is the act of allocating money or resources with the expectation of generating income or profit in the future.

Let x be the amount invested in the second account (with a 4% interest rate).

Then, since Rachel invested $300 more in the first account, the amount invested in the first account (with a 2% interest rate) is (x + 300)

We know that the total interest income Rachel earned was $516. We can set up an equation using the interest formula: (2% means 0.02 and 4% means 0.04)

⇒ 0.02(x + 300) + 0.04x = 516
⇒ 0.02x + 6 + 0.04x = 516
⇒ 0.06x + 6 = 516
⇒ 0.06x = 510
⇒ x = 8500

So, Rachel invested $8500 in the second account (with a 4% interest rate)

and (x + 300) = (8500 + 300) = $8800 in the first account (with a 2% interest rate).

Therefore, Rachel $8500 invested at 4% and $8800 invested at 2%.

based on the information provided, the probability of selecting a yellow disk is 1/5 or 0.2.

How to solve the problem?

The probability of selecting a yellow disk cannot be 2, as probabilities must always be between 0 and 1.

To calculate the probability of selecting a yellow disk, we can use the formula:

P(yellow) = number of yellow disks / total number of disks

From the information given, we know that there are 5 yellow disks and 25 total disks in the bag. Plugging these values into the formula gives:

P(yellow) = 5/25 = 1/5

Therefore, the probability of selecting a yellow disk is 1/5 or 0.2, which is a decimal value between 0 and 1.

It's possible that there was a typo in the original question or answer, or that some other context is missing which would make sense of the answer being 2. However, based on the information provided, the probability of selecting a yellow disk is 1/5 or 0.2.

Answer:

Step-by-step explanation:

Given two sides of a right triangle, we can find the other side using the Pythagorean theorem, which is

[tex]a^2+b^2=c^2[/tex], where a and b are any of the two legs (e.g., you can set 12 can be a or b) and c is the hypotenuse.

If we allow 12 to b a and 13 to be c, we can solve for b, which is the measure of the other side:

[tex]12^2+b^2=13^2\\144+b^2=169\\b^2=25\\b=5\\b=-5[/tex]

When taking the square root of a number, you always get a negative number and a positive number, since squaring a negative gives a positive answer (e.g. 5^2 = 25 and (-5)^2 = 25).  However, because you can't have a negative answer, the answer is simply b = 5 cm

We can even check our answer by making sure that the sum of the square of the two legs equals the square of the hypotenuse:

[tex]12^2+5^2=13^2\\144+25=169\\169=169[/tex]

Sarah's daily outgoings on wages are £892.50.

What is wages?

Wages refer to the payment made to an employee in exchange for their labor or services provided to an employer. It is usually paid on an hourly, daily, weekly or monthly basis, and the amount of wages earned is determined by the hours worked, rate of pay, and any applicable deductions or taxes. Wages can be paid for various types of work, such as manual labor, skilled trades, clerical work, or professional services. It is an essential component of an employee's compensation package and is regulated by labor laws to ensure that employees are fairly compensated for their work.

Each employee works for 8.5 hours a day (17:00 - 08:30 = 8.5). So, the total number of hours worked by 12 employees in a day is 12 employees × 8.5 hours/employee = 102 total hours

Sarah pays each employee £8.75 per hour, so her total daily outgoings on wages can be calculated as,

102 total hours × £8.75 per hour/employee = £892.50

Therefore, Sarah's daily outgoings on wages are £892.50.

The probability that the number generated is:

1). 94 = 1/4, (2). even = 1/4, (3). odd = 0, (4). less than 32 = 1/25, and (5). greater than 74 = 1/25.

The probability of an event occurring is the fraction of the number of required outcome divided by the total number of possible outcomes.

The total possible outcome = 10

probability of generating 94 = 5/10 × 5/10 = 1/4

probability of generating an even number = 5/10 × 5/10 = 1/4 {all numbers ending with 0,2,4,6, and 8 must be even}

probability of generating an odd number = 0 {since the second digit must be from 0,2,4,6, and 8, hence no odd number can be generated}

probability of generating less than 32 = 2/10 × 2/10 = 1/25 {since the first digit must either be 1 or 3, while the second digit must be either 0 or 2}

probability of generating greater than 72 = 2/10 × 2/10 = 1/25 {since the first digit must either be 7 or 9, while the second digit must be either 6 or 8}.

Therefore, the probability that the number generated is:

1). 94 = 1/4, (2). even = 1/4, (3). odd = 0, (4). less than 32 = 1/25, and (5). greater than 74 = 1/25.

If Mike scores two standard deviations above the mean then the Mike's percentile-score is 97.72 ≈ 98 percentile.

The percentile score corresponding to a raw test score, is the probability of the test score of a randomly chosen student to be less than or equal to the given test score.  To calculate this probability we find the value of the cumulative distribution function of the test score random variable at the given test score.

To calculate the percentile score of the given raw test score we have to find the value of the cumulative distribution function for the test score random variable at the given raw test score. if this random variable is X, then the linearly scaled random variable [tex]Z=\frac{X-\mu}{\sigma}[/tex], has standard normal-distribution. here [tex]\mu\textrm{ and }\sigma[/tex] are the mean and the standard deviation of the test score r.v respc. Also [tex]\textrm{P}(X\leq x_0) = \textrm{P}(Z\leq z_0),\textrm{ where }z_0=\frac{x_0-\mu}{\sigma}[/tex].  So instead of finding [tex]\textrm{P}(X\leq x_0)\textrm{, we can find } \textrm{P}(Z\leq z_0)[/tex] instead. [tex]z_0[/tex] is called the z-score corresponding to the [tex]x_0[/tex]. We can find [tex]\textrm{P}(Z < z_0)[/tex], using the table for the standard normal distribution.

For our question, we want to find [tex]\textrm{P}(X\leq \mu + 2\sigma)[/tex]. which is equal to [tex]\textrm{P}(Z\leq \frac{\mu+2\sigma - \mu}{\sigma}) = \textrm{P}(Z\leq 2).[/tex] So the z-score = 2. From the table for the standard normal distribution we get [tex]\textrm{P}(Z\leq 2) = .9772[/tex]. So our percentile score is .9772 or 97.72% [tex]\sim[/tex] 98%.

Step-by-step explanation:

Since ABCD is a parallelogram, its opposite sides are parallel and congruent. Therefore, we have:

AB || CD and AB ≅ CD

AD || BC and AD ≅ BC

Since AC is a diagonal, it divides the parallelogram into two congruent triangles, namely, ΔABC and ΔACD. Therefore, we have:

∠A ≅ ∠D (corresponding angles of congruent triangles)

∠C ≅ ∠B (corresponding angles of congruent triangles)

AB ≅ CD (opposite sides of parallelogram)

AC ≅ AC (reflexive property of congruence)

Now, consider the triangles ΔAEC and ΔCEB. We have:

∠AEC ≅ ∠CEB (vertical angles)

∠ACE ≅ ∠BCE (corresponding angles of congruent triangles ΔABC and ΔACD)

AC ≅ AC (reflexive property of congruence)

Therefore, by the angle-angle-side (AAS) postulate, we can conclude that ΔAEC ≅ ΔCEB. Hence, we have:

CE ≅ AC (corresponding parts of congruent triangles)

BE ≅ DE (corresponding parts of congruent triangles)

Thus, we have proven that line segment AC is congruent to line segment CE, and line segment BE is congruent to line segment DE.
