When we want to calculate an **angle** of a **triangle** we must take into account the following information:

If we know the value of two **angles **(angles 2 and 3) of the triangle we must add the measure of the two angles we know.

55° (angle 2) + 25° (angle 3) = 80°

pleaseeeeeeeeee 3 4/7 -2 1/5 rounded to the nearest half

### Answers

3 4/7 -2 1/5 **rounded **to the **nearest half** is simplified as: 1½

How to Round to the Nearest Half?

To **round **3 and 4/7 - 2 and 1/5 to the **nearest half**, we first need to convert the mixed numbers to improper **fractions**:

3 and 4/7 = (3 x 7 + 4)/7 = 25/7

2 and 1/5 = (2 x 5 + 1)/5 = 11/5

So the expression becomes:

25/7 - 11/5

To simplify this, we need to find a common denominator. The least common multiple of 7 and 5 is 35:

(25/7) x (5/5) = 125/35

(11/5) x (7/7) = 77/35

So the expression becomes:

125/35 - 77/35 = 48/35

To round to the **nearest half**, we need to look at the **fraction **in terms of eighths. To do this, we multiply both the numerator and denominator by 8:

(48/35) x (8/8) = 384/280

Next, we divide the numerator by the denominator and get:

384 ÷ 280 = 1 and 104/280

To **round **to the **nearest half**, we look at the **fraction **104/280 in terms of halves, which is:

(104/280) x (2/2) = 208/560

We can simplify this to:

208/560 = 13/35

Since 13/35 is more than half of a whole (which is 1/2), we **round up **to the **nearest half**. Therefore:

3 and 4/7 - 2 and 1/5 **rounded **to the **nearest half **is 1 and 1/2.

### Answers

The number of **workers **that is closest to but not more than the point of **highest **MPL is 3. and the number of workers resulting in the highest level of average product of labor is also closest to 3.

To find the **marginal **product of labor, we need to calculate the additional output produced by each additional unit of labor.

We can calculate this by finding the **change **in the total product (TP) for each additional unit of labor. The table gives us the following information:

When there are 0 workers, TP = 0

When there is 1 worker, TP = 150

When there are 2 workers, TP = 320

When there are 3 workers, TP = 510

When there are 4 workers, TP = 660

When there are 5 workers, TP = 800

Using this information, we can calculate the marginal **product **of labor (MPL) as follows:

MPL of the 1st worker = TP of 1 worker - TP of 0 workers = 150 - 0 = 150

MPL of the 2nd worker = TP of 2 workers - TP of 1 worker = 320 - 150 = 170

MPL of the 3rd worker = TP of 3 workers - TP of 2 workers = 510 - 320 = 190

MPL of the 4th worker = TP of 4 workers - TP of 3 workers = 660 - 510 = 150

MPL of the 5th worker = TP of 5 workers - TP of 4 workers = 800 - 660 = 140

We can see that the highest marginal product of labor is 190, which **occurs **when there are **3 workers**. Therefore, the number of workers that is **closest **to but not more than the **point **of highest MPL is 3.

A basketball player makes an annual of $2,300,000. A charitable organization states that it can feed 1 child in a developing country for 43¢ per day. The basketball player donates 10% of his annual salary to this organization. How many children will his donation feed for 1 day?

### Answers

By donating** 10% **of the salary a basketball player donates money that can** **feed **534883 children **per day.

**What is percentage?**

A value or **ratio** that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a **percentage** of a number, we should divide it by its entirety and then multiply it by 100. The **proportion** therefore refers to a component per hundred.

The annual income of basketball player is $2,300,000.

The cost to feed 1 child is 43 cents per day.

The basket ball player donates 10% of his annual salary.

Calculate the **percentage** of salary donated by using the formula -

Amount Donated = 10% of Annual income

Plug in the values in the** equation** -

Amount Donated = 10/100 × 2,300,000

Amount Donated = $2,300,00

The amount donated is $2,300,00.

**Convert **dollar to cents -

$1 is equivalent to 100 cents

$2,300,00 is equivalent to 2,300,00 × 100 = 2,300,0000 cents

The number of children that can be fed -

Number of children = Amount donated / Amount needed for 1 child

Substitute the values in the **equation **-

Number of children = 2,300,0000 / 43

Number of children = 534883.721 ≈ 534883 children

Therefore, 534883 children can be fed.

What is Integration?

Integration simply can be defined as the **method **of finding the whole by adding up the parts.

This is actually the reverse process of **differentiation**.

The given integral is, ∫[tex]x\sqrt{1-x}[/tex] dx

**Integration by parts **in an integral is defined as.

∫f(x) g(x) dx = f(x) ∫g(x) - ∫[f'(x)∫g(x)] dx

Let f(x) = x and g(x) = [tex]\sqrt{1-x}[/tex]

Using the formula below, it is possible to determine the **present value** of $70,000 payable in two years at a 4% rate of interest compounded monthly:

PV = FV / (1 + r/n)^(nt)

such that:

Present Value, or PV, is the term.

FV stands for **future **value.

The annual number of **compounding **periods is n, and the interest rate is r.

The **number of years** is t.

PV = $70,000 / (1 + 0.04/12)^(12 × 2)

PV = $70,000 / (1.003333)^24

PV = $70,000 / 1.090777

PV = $64,136.87

The lengths on the figure are not drawn accurately.

### Answers

The value of the **length** of EC to the nearest **whole number** is 78 units.

What is Pythagoras Theorem?

According to Pythagoras's Theorem, the square of the **hypotenuse** side in a right-angled triangle is equal to the sum of the squares of the other two sides. **Perpendicular**, Base, and Hypotenuse are the names of this triangle's three sides. The hypotenuse in this case is the longest side since it forms the reverse of a 90° angle. When a right triangle's sides (let's say, a, b, and c) positive integer values are squared, they are used to create an equation known as a Pythagorean triple.

The given figure has right-triangles formed by the diagonals of the polygon.

We use the Pythagoras Theorem to find the value of EC.

The Pythagoras Theorem is given as:

c² = a² + b²

For the first triangle:

(73)² = a² + (55)²

a = 48

Now for the adjacent triangle with hypotenuse = 60.

(60)² = (48)² + (b)²

b = 36

Triangle with hypotenuse = 86:

(86)² = (a)² + (36)²

a = 78.10

Hence, the value of the length of EC to the nearest whole number is 78 units.

### Answers

(a) The **probability** that the instrument does not** fail** in an **8-hour shift** is 0.7183 or 71.83%.

(b) The **probability** of at least one **failure** in a **24-hour day** is 0.999 or 99.9%.

Poisson Distribution: Failure Probability

The number of failures of a **testing instrument** in a given time period is modeled by a **Poisson** distribution with a rate parameter equal to the mean number of failures per unit time.

(a) To find the probability that the** instrument **does not fail in an 8-hour shift, we can use the **cumulative distribution function** (CDF) of the Poisson distribution. The CDF gives the probability that the number of failures is less than or equal to a given value. In this case, we want to find the probability that there are 0 failures in an **8-hour shift**, so the CDF can be expressed as:

P(X ≤ 0) = e^(-0.025 * 8) = 0.7183

So, the **probability** that the instrument does **not fail **in an 8-hour shift is 0.7183 or 71.83%.

(b) To find the **probability** of at least** one failure **in a 24-hour day, we can subtract the probability of 0 failures from 1. That is,

P(X ≥ 1) = 1 - P(X ≤ 0) = 1 - e^(-0.025 * 24) = 0.999

So, the probability of at least one failure in a 24-hour day is 0.999 or 99.9%.

Note: In these calculations, we use the formula for the cumulative **distribution function** of the Poisson distribution, which is:

P(X ≤ k) = e^(-lambda) * (lambda^k / k!)

D) A town has 870 people. This is after a 45% increase since 2 decades ago.

What was the population before this change? Answer:

### Answers

A) 145% of 600 would be, 870

B) **Population **would be 870.

C)** **The population from two **decades **ago was 600.

D) The population before the change was 600

**What is Percentage?**

To compute a **percentage**, divide the value by the entire **amount **and multiply the result by 100. A **percentage **is a quantity or **ratio **that is stated as a **fraction **of one hundred. The percent **sign**, "%," is **frequently **used to represent it.

A) 145% of 600 is equal to 870. You can **calculate **this by multiplying 600 by 1.45:

600 * 1.45 = 870

B) If there was a 45% **increase **in the **population **since two decades ago, the current population would be, 600 * 1.45 = 870.

C) If the **current population **of a town is 870, which is 145% of its population from two decades ago, we can find the population from two decades ago by dividing 870 by 1.45:

870 / 1.45 = 600

So, the **population **from two **decades **ago was **600.**

D) If the **current population **of a town is 870 and it has gone through a 45% **increase **since two decades ago, we can find the population before this **change **by dividing 870 by 1 + 0.45 = 1.45:

870 / 1.45 = 600

So, the **population before **the **change **was 600.

g problems 25, 26, and 27 of the rhind papyrus are as follows: problem 25. a quantity and its 1 2 added together become 16. what is the quantity? problem 26. a quantity and its 1 4 added together become 15. what is the quantity? problem 27. a quantity and its 1 5 added together become 21. what is the quantity? solve each of these problems by false position, expressing the answers in unit fractions.

### Answers

After solving each of these problems by **false position**, the quantities of problems 25, 26, and 27 are 122/15, 3/20, and 91/20.

Problem 25: Let x be the quantity. Then we have:

x + 1/2 = 16

To solve this equation by false position, we start with a guess of x = 16/2 = 8, since the **quantity **is likely to be close to half of the **sum**. We substitute this value into the equation and find the error:

8 + 1/2 = 8.5

16 - 8.5 = 7.5

Since the error is **negative**, we need to increase our guess by adding a **unit fraction**. The unit fraction that we add is 1/7.5 = 2/15 since the error is 2/15 of the quantity. Thus, our new guess is:

x = 8 + 2/15 = 122/15

We can check that this value satisfies the original equation:

122/15 + 1/2 = 16

Problem 26: Let x be the quantity. Then we have:

x + 1/4 = 15

To solve this equation by false position, we start with a guess of x = 15 - 1/4 = 59/4, since the quantity is likely to be close to the **difference**. We substitute this value into the equation and find the error:

59/4 + 1/4 = 15

15 - 59/4 = -1/4

Since the error is negative, we need to **increase **our guess by adding a unit fraction. The unit fraction that we add is 1/(-1/4) = -4, since the error is 4 times the quantity. Thus, our new guess is:

x = 59/4 - 4 = -5/4

This value is negative, which means that our **initial **guess was too large. We need to decrease our guess by subtracting a unit fraction. The unit fraction that we **subtract **is -1/(-5/4) = 4/5, since the error is 4/5 of the quantity. Thus, our new guess is:

x = -5/4 + 4/5 = 3/20

We can check that this value satisfies the original equation:

3/20 + 1/4 = 15

Problem 27: Let x be the quantity. Then we have:

x + 1/5 = 21

To solve this equation by false position, we start with a guess of x = 21 - 1/5 = 104/5, since the quantity is likely to be close to the difference. We substitute this value into the equation and find the **error**:

104/5 + 1/5 = 21

21 - 104/5 = -4/5

Since the error is negative, we need to increase our guess by adding a unit fraction. The unit fraction that we **add **is 1/(-4/5) = -5/4 since the error is 5/4 of the quantity. Thus, our new **guess **is:

x = 104/5 - 5/4 = 91/20

We can check that this value satisfies the original equation:

91/20 + 1/5 = 21.
