Given a salary of $14 per hour, the pay for the following day of a weekly time card is $126.

It is the sum of money an employee receives in exchange for the job they perform. A monthly salary, annual salary, or hourly rate are the most common ways to convey it.

Pay = (4 hours x $14/hr) + (5 hours x $14/hr)

      = $126

The wage rate must be increased by the number of hours performed in order to determine the pay for the day.

The wage rate is $14/hr.

A 4 hour morning shift and a 5 hour afternoon shift were performed by the employee. Therefore, the day's salary is calculated using the following formula:

(4 hours x $14/hr) + (5 hours x $14/hr) = $126.

If you round this amount to the nearest hundredth, your total pay will be $126.00.

Monday  08:00  12:00   4hrs  *  $14   $56.00

                12:15    17:30   5hrs * $14    $70.00

                                        Total wages $126.00

It's crucial to maintain precise records of the hours worked each day to make sure the employee is paid correctly.

This covers the hours they arrive at work, leave at the end of the day, and any pauses they take. The employee's salary can then be calculated with accuracy using this information.

Answer:

The two figures are not equal because 3/5 doesn't does not equal 6/9

Step-by-step explanation:

The numbers just aren't equal.

The total interest paid by him to the bank would be: Rs. 28,500. Ram should have waited for 3 years, to start his business without borrowing extra loan, until the age of 19.

What is an interest?

Let the sum deposited by Ram at the age of 16 be x.

After compounding for n years, the balance becomes x(1.1)^n.

As per the given condition, we have:

x*[tex](1.1)^{n}[/tex] = 121x

[tex](1.1)^{n}[/tex] = 121

n = 2

So, after two years, Ram's balance became 121 times the initial principal.

After this, he deposited 1/4 of the existing balance, i.e. 1/4 * 121x = 30.25x

After one year of this deposit, the balance becomes 30.25x * 1.2 = 36.3x

So, Ram's total balance at the age of 19 becomes 121x + 36.3x = 157.3x

This is given to be Rs. 359 less than thrice of the initial principal, i.e.

157.3x = 3x - 359

Solving this equation, we get:

x = Rs. 480

So, the sum deposited by Ram at the age of 16 was Rs. 480.

Now, he borrowed Rs. 1,10,000 at 15% p.a. compounded annually.

The interest for the first year would be (15/100) * 1,10,000 = Rs. 16,500

After paying this interest, the remaining balance becomes:

1,10,000 + 16,500 = Rs. 1,26,500

Now, he cleared his debt by paying equal installments in the next 2 years and 1 year.

Let the equal installment be x.

So, the balance after the first year becomes:

1.15x + (1.15)²x + (1.15)³x - x = 1,26,500

Solving this equation, we get:

x = Rs. 45,000

So, Ram paid a total of Rs. 1,35,000 to clear his debt.

The total interest paid by him to the bank would be:

16,500 + 0.15 * 45,000 + 0.15 * 45,000 + 0.15 * 45,000 = Rs. 28,500

To start his business without borrowing extra loan, Ram should have waited for 3 years, until the age of 19, when his balance was Rs. 157.3x = Rs. 75,264. With an interest rate of 20% p.a. simple interest, the balance would become:

75,264 + 0.2 * 75,264 = Rs. 90,316.8

This amount would be sufficient for him to start his business without borrowing extra loan.

the perpendicular or opposite side is approximately 10.42 units long.

How to solve the triangle?

In a right triangle, the side opposite the 90-degree angle is called the hypotenuse, and the side opposite the 15-degree angle is called the opposite side or perpendicular. The third side, adjacent to the 15-degree angle and the right angle, is called the adjacent side.

Using trigonometric functions, we can relate the angles and sides of a right triangle. In this case, we can use the tangent function, which is defined as the ratio of the opposite side to the adjacent side:

tan(15) = opposite/adjacent

We are given the hypotenuse, which is the hypotenuse, and we can use the Pythagorean theorem to find the adjacent side:

adjacent = sqrt(hypotenuse² - opposite²)

Substituting the value of the hypotenuse and rearranging the above equation we get:

opposite = √(hypotenuse² / (1 + tan(15)²))

Plugging in the values, we get:

opposite = √(12² / (1 + tan(15)²))

= √(144 / (1 + 0.2679))

= ²(108.5)

= 10.42

Therefore, the perpendicular or opposite side is approximately 10.42 units long.

The probability of no successes in eight trials of a binomial experiment with a probability of success of 7% is 0.6%

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain to occur.

Probability can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. The resulting value represents the likelihood of the event occurring. For example, if a coin is tossed, the probability of it landing heads up is 0.5 (assuming a fair coin), because there is one favorable outcome (heads) out of two possible outcomes (heads or tails).

The probability of no successes in eight trials of a binomial experiment can be calculated using the binomial probability formula:

P(X = 0) = (n choose k) × pᵏ × (1-p)ⁿ⁻ᵏ

where:

n = number of trials = 8

k = number of successes = 0

p = probability of success = 7% = 0.07

Substituting the values in the formula, we get:

P(X = 0) = (8 choose 0) × 0.07⁰ × (1-0.07)⁸⁻⁰

= 1 × 1 × 0.569

= 0.569

Therefore, the probability of no successes in eight trials of a binomial experiment with a probability of success of 7% is 0.6%, rounded to the nearest tenth of a percent.

The length of XZ in adjoining figure  is 80/3 cm

Rectangular surfaces refer to flat two-dimensional shapes that have four straight sides and four right angles, where opposite sides are parallel and equal in length. They are called rectangular because they can be formed by taking a rectangle and flattening it out into a plane. Examples of rectangular surfaces include sheets of paper, computer screens, tabletops, and walls of rectangular rooms. The area of a rectangular surface is calculated by multiplying the length and width of the rectangle.

Let the length, width, and height of the rectangular prism be x, y, and z, respectively. Then, we have:

xy = 720 (since the area of the rectangular surfaces of the prism is 720 sq. cm)

XX' = 20

Let XY = 5k, XZ = 4k, and YZ = 3k (since XY : XZ: YZ = 5:3:4).

Using the Pythagorean theorem, we can find the value of k as follows:

XX²+ XZ²= ZZ²

20²+ (4k)²= (5k)²

400 + 16k² = 25k²

9k² = 400

k² = 400/9

f( - 2 ) = 0 for the given piecewise function.

To find f( - 2 ) for the given piecewise function, we need to determine which part of the function applies to the input value x = - 2.

Since - 2 is less than or equal to - 1, we use the first part of the function where f(x) = x + 2 for x ≤ - 1.

Now, substitute x = - 2 into the first part of the function:

(B) r = 0.0804 * 100% = 8.04%

(C) value in 2009 = $11,650

What is the rate of change?

The rate of change is a mathematical concept that measures how much one quantity changes with respect to a change in another quantity. It is the ratio of the change in the output value of a function to the change in the input value of the function. It describes how fast or slow a variable is changing over time or distance.

A) The initial value is $44,000 and the final value is $15,000. The time elapsed is 2006 - 1992 = 14 years.

Using the formula for an annual rate of change (r):

final value = initial value * [tex](1 - r)^t[/tex]

where t is the number of years and r is the annual rate of change expressed as a decimal.

Substituting the given values, we get:

$15,000 = $44,000 * (1 - r)¹⁴

Solving for r, we get:

r = 0.0804

So, the annual rate of change between 1992 and 2006 was 0.0804 or approximately 0.0804.

B) To express the rate of change in percentage form, we need to multiply by 100 and add a percent sign:

r = 0.0804 * 100% = 8.04%

C) Assuming the car value continues to drop by the same percentage, we can use the same formula as before to find the value in the year 2009. The time elapsed from 2006 to 2009 is 3 years.

Substituting the known values, we get:

value in 2009 = $15,000 * (1 - 0.0804)³

value in 2009 = $11,628.40

Rounding to the nearest $50, we get:

value in 2009 = $11,650

Hence, (A) the annual rate of change between 1992 and 2006 was 0.0804

(B) r = 0.0804 * 100% = 8.04%

The probability that a particular bulb will last from 2772 to 3298 hours is 2.66.

In mathematics, the term average is referred to as the mean value, which is equal to the ratio of the sum of all the values in a given set to all the values in the set.

Here we have been given,

A brand of lightbulb lasts on average 2821 hours with a standard deviation of 197 hours.

Assuming the life of the lightbulb is normally distributed, and we need to find the probability that a particular bulb will last from 2772 to 3298 hours.

According to the given problem, we know that the value of the following is defined as follows:

Average = 2821

Standard deviation = 197

Now, based on the z score concept, the value of the required probability is calculated as,

=> z = (x-mean)/ sd

=> z lower = (2821 - 3298)/197= -2.42

=> z upper = (2821- 2772)/197= 0.24

Therefore, the probability is calculated as,

=> z upper - z lower

=> 0.24 - (-2.42)

=> 2.66

To create a histogram of the number of years that each of the nine Omar's Omelette Operation locations has been open, we can start by organizing the data into groups or bins.

A histogram is a graphical representation of a distribution of data, typically shown as bars of different heights. In this case, we can use bins of equal width, such as 1 or 2 years. Then, we can count the number of values that fall into each bin and represent this count as the height of the corresponding bar.

For example, if we use bins of width 2 years, we can group the data into the following bins: [0, 2), [2, 4), [4, 6), [6, 8), [8, 10), and [10, 12). Then, we can count the number of values that fall into each bin and create a bar chart with bars of different heights corresponding to these counts.

The resulting histogram would show the distribution of the number of years that the Omar's Omelette Operation locations have been open, and we could use it to analyze the central tendency, variability, and shape of the data.
