Answer:

sin(theta) = -3/5.

Step-by-step explanation:

We know that tan(theta) = 3/4, which means that the ratio of the opposite side to the adjacent side of a right triangle with angle theta is 3/4. We can use the Pythagorean theorem to find the hypotenuse of the triangle:

hypotenuse^2 = opposite^2 + adjacent^2

hypotenuse^2 = (3^2) + (4^2)

hypotenuse^2 = 9 + 16

hypotenuse^2 = 25

hypotenuse = 5

Since 180 degrees < theta < 270 degrees, we know that theta is in the third quadrant, where the sine function is negative. Therefore, sin(theta) = -opposite/hypotenuse = -3/5.

So, sin(theta) = -3/5.

The measure of angle subtended by the arc CEB is 210⁰.

The value of m∠CDB is 30⁰.

The measure of angle subtended by the arc CEB is calculated by applying the following formula.

The sum of angles in a circle = 360⁰, so the value of arc CEB is calculated as;

arc CEB = 360 - 150⁰

arc CEB = 210⁰

Based on the angle of intersecting chord theorem, we will have the following equation to determine the value of m∠CDB.

m∠CDB = ¹/₂ (210 - 150)

m∠CDB = 30⁰

The probability that Ben will make three out of his next five free throws is approximately 0.3456

Assuming that each free throw attempt is independent of the others, we can use the binomial distribution to calculate the probability of Ben making three out of his next five free throws.

The probability of making a free throw is 0.6, so the probability of missing a free throw is 0.4. Let X be the number of successful free throws out of 5 attempts. Then X follows a binomial distribution with n = 5 and p = 0.6.

The probability of making three out of five free throws can be calculated as follows

P(X = 3) = (5 choose 3) × (0.6)^3 × (0.4)^2

where (5 choose 3) = 10 is the number of ways to choose 3 successful free throws out of 5 attempts.

Using a calculator, we get

P(X = 3) = 0.3456

If the money box has 600 coins that consist of 20 cents and 50 cents, the total amount of cents in the money box is 24,000 cents.

To determine the total amount of cents in Thabang's money box, we need to know how many of the 600 coins are 20 cents and how many are 50 cents. Let's use variables to represent these quantities.

Let x be the number of 20 cent coins, and y be the number of 50 cent coins. We know that the total number of coins is 600, so we have:

x + y = 600

We also know that the value of each 20 cent coin is 20 cents, and the value of each 50 cent coin is 50 cents. So the total value of the coins in the money box is:

20x + 50y

To find the total amount of cents in the money box, we need to simplify and solve for the value of the expression above. We can do this by using the equation we have for x and y and substituting y = 600 - x:

20x + 50(600 - x) = 20x + 30000 - 50x = -30x + 30000

So the total value of the coins in the money box is -30x + 30000 cents. We don't know the value of x yet, but we know that x and y must be non-negative integers and x + y = 600.

We can solve for x by trying different values of x until we find one that satisfies these conditions. For example, if we set x = 200, then y = 400 and the conditions are satisfied. Therefore, the total amount of cents in the money box is:

-30x + 30000 = -30(200) + 30000 = 24000

To multiply 9200 and 2.3 x 10^3 in scientific notation, we need to multiply their coefficients and add their exponents.

9200 x 2.3 x 10^3 = 21,160,000

Since the product is greater than 10, we need to adjust the coefficient and the exponent to express the number in scientific notation. We can move the decimal point to the left until there is only one digit to the left of the decimal point, and count how many places we moved the decimal point. In this case, we need to move the decimal point 7 places to the left:

2.116 x 10^7

Therefore, the product of 9200 and 2.3 x 10^3 expressed in scientific notation is 2.116 x 10^7.

The value for theta is 16.7 degrees and that of alpha is 73.3 degrees.

Trigonometric functions are also known as Circular Functions can be simply defined as the functions of an angle of a triangle. It means that the relationship between the angles and sides of a triangle are given by these trig functions

The tangent function is the ratio of the length of the opposite side to that of the adjacent side. It should be noted that the tan can also be represented in terms of sine and cos as their ratio.

To find alpha, we can take the inverse tangent of both sides of the equation:

tan α = 10/3

tan⁻¹(tan α) = tan⁻¹(10/3)

α = tan⁻¹(10/3)

Using a calculator, we get:

α ≈ 73.3 degrees (rounded to one decimal place)

Therefore, the value of alpha is approximately 73.3 degrees.

To find theta, we can take the inverse tangent of both sides of the equation:

tan θ = 3/10

tan⁻¹(tan θ) = tan⁻¹(3/10)

θ = tan⁻¹(3/10)

Using a calculator, we get:

θ ≈ 16.7 degrees (rounded to one decimal place)

Therefore, the value of theta is approximately 16.7 degrees.\

The area of the triangle with vertices (-1, 1), (-1, 5), and (4, 1) is 10 square units.

The area of a triangle is a measure of the amount of space inside the triangle. It is defined as half the product of the base of the triangle and its corresponding height.

If a triangle has base length b and corresponding height h, then its area A is given by the formula:

A = (1/2) × b ×h.

In the given question,

To find the area of the triangle with vertices (-1, 1), (-1, 5), and (4, 1), we can use the formula: A = (1/2) × b ×h.

where the base is the distance between two vertices of the triangle and the height is the perpendicular distance from the third vertex to the base.

We can choose any two points as the endpoints of the base, but it may be easiest to use the points (-1, 1) and (4, 1), since the height will be the vertical distance from the third vertex (which is ( -1, 5)) to the base.

The distance between (-1, 1) and (4, 1) is: base = 4 - (-1) = 5

To find the height, we need to determine the perpendicular distance from the point (-1, 5) to the line containing the base. This can be done by finding the equation of the line containing the base and then finding the distance from the point (-1, 5) to that line.

The equation of the line containing the base is: y = 1

since the line is horizontal and passes through the point (4, 1) and (-1, 1).

The distance from the point (-1, 5) to the line y = 1 is:

height = |5 - 1| = 4

where the absolute value is taken to ensure that the height is positive.

Now, we can substitute the values of the base and height into the formula for the area:

Area = (1/2) × base × height

= (1/2) * 5 * 4

= 10

Therefore, the area of the triangle with vertices (-1, 1), (-1, 5), and (4, 1) is 10 square units.

To evaluate the expression is

7√3 / (√10 + √3) - 2√5 / (√6 + √5) - 3√2 / (√15 + 3√2)

we need to rationalize the denominators of each fraction. To do this, we can multiply both the numerator and denominator of each fraction by the conjugate of the denominator.

For the first fraction, we can multiply the numerator and denominator by (√10 - √3):

7√3(√10 - √3) / [(√10 + √3)(√10 - √3)]

Simplifying the denominator gives:

7√3(√10 - √3) / 10 - 3

For the second fraction, we can multiply the numerator and denominator by (√6 - √5):

-2√5(√6 - √5) / [(√6 + √5)(√6 - √5)]

Simplifying the denominator gives:

-2√5(√6 - √5) / 6 - 5

For the third fraction, we can multiply the numerator and denominator by (√15 - 3√2):

-3√2(√15 - 3√2) / [(√15 + 3√2)(√15 - 3√2)]

Simplifying the denominator gives:

-3√2(√15 - 3√2) / 15 - 9

Now, we can simplify each expression separately and then combine them:

7√3(√10 - √3) / 7 = √30 - 3

-2√5(√6 - √5) / 1 = -2√6 + 2√5

-3√2(√15 - 3√2) / 6 = -√30 + 9

Combining the expressions gives:

√30 - 3 - 2√6 + 2√5 - √30 + 9

Simplifying further gives:

2√5 - 2√6 + 6

Therefore, the value of the expression 7√3 / (√10 + √3) - 2√5 / (√6 + √5) - 3√2 / (√15 + 3√2) is 2√5 - 2√6 + 6.

Therefore, the probability of Mrs. Vo winning is 1 - 91/300 - 8/21 = 11/30.

Probability refers to the likelihood or chance that a particular event or outcome will occur. It is a mathematical concept that quantifies the degree of uncertainty associated with an event or situation. Probability is typically expressed as a number between 0 and 1, where 0 indicates that an event is impossible, and 1 indicates that it is certain to occur.

by the question.

let's consider the first case: Mrs. Vo spins a number greater than 65 on her first spin. There are a total of 8 numbers greater than 65 on the wheel: 70, 75, 80, 85, 90, 95, 100. Since there are 21 sections on the wheel, the probability of spinning a number greater than 65 on the first spin is 8/21.

The number of possible outcomes for Mrs. Vo's spin is 21, since there are 21 equal portions on the wheel. However, we need to exclude the outcomes that would cause Mrs. Vo's sum to exceed 100, since that would result in an automatic loss. The largest possible outcome on the wheel is 100, so Mrs. Vo cannot spin a number greater than or equal to 35 on her first spin.

The number of outcomes that would give Mrs. Vo a winning sum of at least 66 is the number of outcomes greater than 65, which are 70, 75, 80, 85, 90, 95, and 100. There are 7 such outcomes.

If Mrs. Vo spins a number less than or equal to 65 on her first spin, the probability of this happening is 13/21. The probability of her second spin being between 1 and 35 is 35/100 (since there are 35 numbers between 1 and 35 on the wheel). So, the probability of her total sum being less than or equal to 65 is (13/21) * (35/100) = 91/300.
