Answer:

(i) This equation is not true, which means that the three squares cannot exactly surround a right-angled triangle.

(ii) It is not always possible for three squares to surround a right-angled triangle. One way to see this is to note that the side lengths of a right-angled triangle satisfy the Pythagorean theorem, which means that they must be in a certain relationship to each other. On the other hand, the areas of three squares can take any values, so it is not always possible to find three squares whose side lengths satisfy the Pythagorean theorem.

Step-by-step explanation:

To determine whether the three squares can exactly surround a right-angled triangle, we need to use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

Let's assume that the three squares have side lengths a, b, and c, with areas of 7 cm², 17 cm², and 10 cm², respectively. Then, we have:

a² = 7 cm²

b² = 17 cm²

c² = 10 cm²

We need to find out whether there exist values of a, b, and c that satisfy the Pythagorean theorem. If such values exist, then the three squares can surround a right-angled triangle.

We can rearrange the equations above to solve for a, b, and c:

a = √7 cm ≈ 2.65 cm

b = √17 cm ≈ 4.12 cm

c = √10 cm ≈ 3.16 cm

Now, we can check whether the Pythagorean theorem holds:

c² = a² + b²

(√10 cm)² = (√7 cm)² + (√17 cm)²

10 cm = 7 cm + 17 cm

This equation is not true, which means that the three squares cannot exactly surround a right-angled triangle.

In general, it is not always possible for three squares to surround a right-angled triangle. One way to see this is to note that the side lengths of a right-angled triangle satisfy the Pythagorean theorem, which means that they must be in a certain relationship to each other. On the other hand, the areas of three squares can take any values, so it is not always possible to find three squares whose side lengths satisfy the Pythagorean theorem.

Answer:

Step-by-step explanation:

To find the area of a triangle, we can use the formula:

Area = (1/2) × base × height

In this case, we have three sides of the triangle given: 5, 3, and 4. To use these to find the area, we need to first determine which side is the base and what the corresponding height is.

We can see that the side with length 5 is opposite the biggest angle, so this is likely the hypotenuse. The other two sides, 3 and 4, must then be the other two legs of a right triangle, with one of them being the base and the other the height.

To determine which is which, we can use the Pythagorean theorem:

c^2 = a^2 + b^2

where c is the hypotenuse and a and b are the other two sides. In this case, we have:

5^2 = 3^2 + 4^2

25 = 9 + 16

So we have confirmed that 3 and 4 are indeed the legs of a right triangle, with 5 as the hypotenuse. We can use the Pythagorean theorem again to find the height:

a^2 + b^2 = c^2

b^2 = c^2 - a^2

b = sqrt(c^2 - a^2)    (taking the positive square root because b is a length)

b = sqrt(5^2 - 3^2)

b = sqrt(16)

b = 4

So the height of the triangle is 4. We can now use the formula to find the area:

Area = (1/2) × base × height

Area = (1/2) × 3 × 4

Area = 6

Therefore, the area of the triangle is 6 square units.

The sample points of events A, B, A ∩ B, A ∪ B and A' (complement of A) are given. The probability of event are 1/18, 11/36, 1/18, 7/18 and 17/18 respectively. The probability using additive rule of p(A ∩ B) is 1/36.  Events A and B are not mutually exclusive as they have a non-empty intersection.

Sample points in the events

A: {(1, 6), (2, 5), (3, 4), (4, 3), (5, 2), (6, 1)}

A ∪ B: {(1, 4), (1, 6), (2, 4), (2, 5), (3, 4), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6), (5, 2), (5, 4), (6, 1), (6, 4)}

A' (complement of A): {(1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3), (5, 1), (5, 3), (5, 5), (6, 2), (6, 3), (6, 5), (1, 5), (1, 6), (2, 6), (3, 5), (3, 6), (5, 6), (6, 6)}

The probability of event A is

p(A) = 2/36 = 1/18.

The probability of event B is

p(B) = 11/36.

The probability of event

A ∩ B (i.e., A and B) is p(A ∩ B) = 2/36 = 1/18.

The probability of event

A ∪ B (i.e., A or B) is p(A ∪ B) = 14/36 = 7/18.

The probability of event A' (i.e., not A) is p(A') = 17/18.

By the additive rule, we have p(A ∪ B) = p(A) + p(B) - p(A ∩ B). Therefore, p(A ∩ B) = p(A) + p(B) - p(A ∪ B) = (1/18) + (11/36) - (7/18) = 1/36. This inconsistent with the answer we obtained in above part.

The events A and B are not mutually exclusive because it is possible to roll a 4 and a 3 at the same time, which satisfies both events.

Both events A and B have probabilities of 1/12, and they are independent events since the outcome on one die does not affect the outcome on the other die.

The event A consists of all outcomes in which the number of spots showing on the red die is three or less.

Since the red die has six equally likely outcomes (1, 2, 3, 4, 5, and 6), the probability of A is:

P(A) = the number of outcomes in A / the total number of possible outcomes.

Out of the six possible outcomes on the red die, three of them are three or less: 1, 2, and 3.

Therefore, the number of outcomes in A is three.

Since there are six equally likely outcomes for the green die as well, the total number of possible outcomes is 6 x 6 = 36.

Therefore, we have:

P(A) = 3/36 = 1/12.

The event B consists of all outcomes in which the number of spots showing on the green die is more than three.

There are also three outcomes on the green die that satisfy this condition: 4, 5, and 6.

Thus, we have:

The measure of angle C is 80°

A cyclic quadrilateral is a quadrilateral which has all its four vertices lying on a circle. It can also be called inscribed quadrilateral.

A theorem if circle geometry states that the opposite angles of a cyclic quadrilateral are supplementary. This means the sum of. opposite angles of a cyclic quadrilateral is 180°

Therefore 3x-59+2x-1 = 180

5x -60 = 180

5x = 180+60

5x = 240

x = 240/5

x = 48

angle A = 2x+4 = 2×48+4

= 100°

therefore angle C = 180-(angle A)

C = 180-100

= 80°

According to the given information, Julie's new bank balance was $1,609.01

To calculate Julie's new bank balance, we need to subtract the total amount of checks she wrote from her initial balance, and then add the total amount of deposits she made.

Total amount of checks = $62.41 + $224.14 + $12.92 + $357.16 = $656.63

Total amount of deposits = $197.34 + $879.13 = $1,076.47

New bank balance = Initial balance - Total amount of checks + Total amount of deposits

New bank balance = $1,189.17 - $656.63 + $1,076.47

The answer of the given question based on the circle is ,  the answer is option (d) 8/3π.

In geometry, an arc is  portion of circumference of a circle. It is  curved line that connects two points on  circle. The length of arc is proportional to the angle that it subtends at the center of the circle.

Since EFB is a straight line and EB is a diameter of the circle, angle EFB subtends the entire circle at F. Therefore, the angle subtended by arc EFD is the difference between the angles subtended by arcs EF and EB.

Arc EF subtends a full circle at F, so its angle is 2π radians. Arc EB subtends a straight angle at F, so its angle is π radians.

Therefore, the angle subtended by arc EFD is:

2π - π = π

The length of arc is given by formula L = rθ, where r is  radius of  circle and θ is  angle (in radians) subtended by  arc at  center of  circle.

In this case, r = 4 and θ = π, so the length of the arc corresponding to angle EFD is:

L = rθ = 4π

To solve the quadratic equation 2x^2 + x - 3 = 0 by factoring, we follow these steps:

Step 1: Write the equation in standard quadratic form, which is ax^2 + bx + c = 0. In this case, the equation is already in standard form: 2x^2 + x - 3 = 0.

Step 2: Factor the quadratic expression on the left-hand side of the equation. We look for two numbers that multiply to give us the constant term (c) and add to give us the coefficient of the linear term (b). In this case, c = -3 and b = 1.

The two numbers that satisfy these conditions are -3 and 1, as -3 * 1 = -3 and -3 + 1 = -2.

Step 3: Use the factored form to set each factor equal to zero and solve for x.

2x^2 + x - 3 = 0

(2x - 3)(x + 1) = 0 (factored form)

Setting each factor equal to zero:

2x - 3 = 0

2x = 3

x = 3/2

x + 1 = 0

x = -1

So the solutions to the equation are x = 3/2 and x = -1.

Step-by-step explanation:

Given statement: For log normally distributed returns, the annual geometric average return is always greater than the arithmetic average return.

The given statement is true.

This is because log normal distribution assumes that the rate of return is compounded continuously, which leads to a higher final value of the investment.

For lognormally distributed returns, the geometric average return is greater than the arithmetic average return.

This is because the lognormal distribution has a positive skew, meaning that there are more small positive returns and fewer large negative returns.

This leads to compounding effects over time, which favor the geometric average return.

The geometric average return is calculated by taking the nth root of the product of (1+Ri),

where Ri is the return for the ith period.

The arithmetic average return is calculated by taking the average of the returns over a period.

Therefore, for lognormally distributed returns, the geometric average return is greater than the arithmetic average return.

The geometric average return takes into account the compounding effect, whereas the arithmetic average return does not.

The probability that at least 10 of them support tuition-free college is 0.9838.

To answer this question, we will use the binomial distribution formula. Let p = 0.51 be the proportion of young Americans who support tuition-free college, and let n = 30 be the sample size.

The probability of at least 10 UConn students supporting tuition-free college is equal to the sum of the probabilities of 10 or more, 11 or more, 12 or more, ..., up to 30. We can use the normal approximation to the binomial distribution.

Using the normal approximation, we first calculate the mean and standard deviation of the binomial distribution:
mean = np = 30 * 0.51 = 15.3
standard deviation = sqrt(np(1-p)) = sqrt(30 * 0.51 * 0.49) = 2.46

We then standardize the variable X = number of UConn students who support tuition-free college:
Z = (X - mean) / standard deviation

Now we want to find the probability that X is greater than or equal to 10, which is equivalent to finding the probability that Z is greater than or equal to (10 - 15.3) / 2.46 = -2.14.

Using a standard normal table or calculator, we find that the probability of Z being greater than or equal to -2.14 is approximately 0.9838. Therefore, the probability of at least 10 UConn students supporting tuition-free college is approximately 0.9838.

It would take the two pumps working together approximately 240 minutes to remove the water.

To determine how long it would take the two pumps to remove the water working together, we can use the concept of work rates. Specifically, we can determine the work rates of each pump and then add them together to find the combined work rate when both pumps are working together.

Let's start by defining some variables:

Let L be the rate of the larger pump, in units of water volume per minute.

Let S be the rate of the smaller pump, in the same units as L.

Let T be the time it takes for both pumps to remove the water working together, in minutes.

From the problem statement, we know that the larger pump can remove all the water alone in 240 minutes. This means that its work rate is 1/240, since it can remove 1 unit of water volume in 240 minutes. Similarly, the smaller pump has a work rate of 1/400.

When both pumps are working together, their work rates add up. Therefore, we can set up an equation as follows:

L + S = 1/T

Substituting the work rates we found earlier, we get:

1/240 + 1/400 = 1/T

Simplifying this equation, we get:

1/T = 0.0041667

Solving for T, we get:
