With the probability that 75% of students favor a difficult final exam, the 95% confidence interval based 60 students for sample proportion is ( 0.64, 0.86).

We have to investigate the believability of my results.

Sample size, n = 60

Confidence nterval = 95%

Sample proportion for students who favour the difficulty of exam, [tex] \hat p[/tex] = 75% = 0.75

We have to determine 95% confidence interval based 60 students. Using the confidence interval formula or sample proportion, [tex]CI = \hat p ± z^* \sqrt{\frac{\hat p ( 1 - \hat p )}{n}}[/tex]

Now, using the Z-distribution table, the value z- score for 95% of confidence interval is equals to 1.96.

Substitute all known values in above formula, [tex]= 0.75 ± 1.96 \sqrt{ \frac{ 0.75( 1- 0.75)}{60}}[/tex]

= 0.75 ± 0.11

= ( 0.64, 0.86)

Hence, required value of interval is ( 0.64, 0.86), i.e., 0.64 < p < 0.86.

The quadratic equation y = x²-6x+5 is minimum because the coefficient of x² is positive.

x = [tex]\frac{-b}{2a}[/tex], but a = 1 and b = -6

therefore x = [tex]\frac{-(-6)}{2(1)}[/tex] = 3

By plugging the value in the quadratic equation above, then we have

y = (3)² - 6(3) + 5 = -4 = -4

Note that y is the y-value of the vertex.

To determine whether the function y = x^2 - 6x + 5 has a maximum or minimum value, we can use the vertex formula, which gives the x-coordinate of the vertex of a quadratic function as -b/2a.

Step-by-step explanation:

∠ ABC is the angle on the circle subtended by the diameter AC

it is the angle in a semicircle and is 90°

A possible solution to the equation cos(x+2)=sin(3x) is x = 22 degrees

The correct answer is an option (C)

Consider a trigonometric equation,

cos(x+2) = sin(3x)

For value x = 0.5 degrees,

cos(x + 2) = cos(2.5)

                = 0.999

and sin(3x) = sin(1.5)

                 = 0.026

For x = 1 degree,

cos(x + 2) = cos(3)

                =0.9986

sin(3x) = sin(3)

           = 0.052

For x = 22 degrees

cos(x + 2) = cos(24)

                = 0.913

sin(3x) = sin(66)

           = 0.913

for x = 44 degrees,

cos(x + 2) = cos(46)

                = 0.69

sin(3x) = sin(132)

           = 0.743

Therefore, the solution to an equation cos(x+2) = sin(3x) is x = 22 degrees

At a function x = 4 has a vertical asymptote and at y = -15 has a horizontal asymptote.

The general form of a function is x= a and y = b.

f(x) = (kx + m) / (x - a) + b

k and m are constants.

We require a factor of (x - 4) in the denominator to get a vertical asymptote at x = 4. It is necessary for the fraction to approach -15 when x approaches positive or negative infinity in order to obtain a horizontal asymptote at y = -15.

One potential function that meets these specifications is:

H(x) = 6/(x - 4) - 15 + k

where k is a constant that establishes the function's vertical shift (i.e., its value at x = 0).

By entering a point on the graph, such as the x-intercept (where y = 0), the value of k can be determined:

0 = 6/(x - 4) - 15 + k

15 - k = 6/(x - 4)

x - 4 = 6/(15 - k)

x = 6/(15 - k) + 4

We may enter this value of x into the original equation to find k since y = 0 at the x-intercept:

0 = 6/((6/(15 - k) + 4) - 4) - 15 + k

0 = 6/(6/(15 - k)) - 15 + k

0 = 15 - k - 15 + k

The x-intercept and asymptotes are unaffected by the value of k, and any value of k will result in a function with the same asymptotes. K does, however, have an impact on the function's vertical shift.

We can select a value for k and then search for a specific function that has the specified asymptotes.

For instance, if we select k = 0, we obtain:

H(x) = 6/(x - 4) - 15

This function has the same shape as the original function H(x) presented in the problem and asymptotes at x = 4 and y = -15, respectively.

the values of k for which the equation 2x² + x + 4k has (a) two real solutions are k < 1/32, (b) one real solution is k = 1/32, and (c) no real solutions are k > 1/32.

How to solve the question?

The given equation is 2x² + x + 4k.

(a) For the equation to have two real solutions, the discriminant b² - 4ac must be positive.

Therefore, for this equation, b² - 4ac > 0

=> 1 - 4(2)(4k) > 0

=> 1 - 32k > 0

=> k < 1/32

Hence, all values of k less than 1/32 will give the equation 2x² + x + 4k two real solutions.

(b) For the equation to have one real solution, the discriminant b² - 4ac must be zero.

Therefore, for this equation, b² - 4ac = 0

=> 1 - 4(2)(4k) = 0

=> 1 - 32k = 0

=> k = 1/32

Hence, only the value of k equal to 1/32 will give the equation 2x² + x + 4k one real solution.

(c) For the equation to have no real solutions, the discriminant b² - 4ac must be negative.

Therefore, for this equation, b² - 4ac < 0

=> 1 - 4(2)(4k) < 0

=> 1 - 32k < 0

=> k > 1/32

Hence, all values of k greater than 1/32 will give the equation 2x² + x + 4k no real solutions.

In conclusion, the values of k for which the equation 2x² + x + 4k has (a) two real solutions are k < 1/32, (b) one real solution is k = 1/32, and (c) no real solutions are k > 1/32.

The equivalent expression for 6r in terms of s is 20s, which we obtain by substituting the value of r from the given equation and simplifying.

The given equation, r = (10/3)s, shows that there is a proportional relationship between the variables r and s. This means that when one variable changes, the other variable changes in direct proportion to it. In other words, if we increase r by a certain factor, s will increase by the same factor, and vice versa.

To find an expression that is equivalent to 6r, we can substitute the value of r from the given equation and simplify.

r = (10/3)s (given equation)

6r = 6(10/3)s (substitute 6r for r in the equation)

6r = 20s (simplify by multiplying 6 and 10/3)

Therefore, the expression that is equivalent to 6r in terms of s is 20s. This means that if we know the value of s, we can use this expression to find the value of 6r in a proportional relationship. For example, if s = 2, then 6r = 20s = 20(2) = 40.

On solving the provided question we can say that As a result, because the Pythagorean theorem is not met, the presented numbers do not represent the sides of a right triangle.

The Pythagorean Theorem is the fundamental Euclidean geometry relationship between the three sides of a right triangle. According to this rule, the area of a square with the hypotenuse side equals the sum of the areas of squares with the other two sides. According to the Pythagorean Theorem, the square that spans the hypotenuse of a right triangle opposite the right angle equals the sum of the squares that span its sides. It is sometimes expressed as a2 + b2 = c2 in general algebraic notation.

The supplied figures reflect the lengths of the three sides of a right triangle, with the hypotenuse (the side opposite the right angle) being 5.47722557505, and the other two sides being 2.2360679775 and 5.

The sum of the squares of the two shorter sides of a right triangle is equal to the square of the hypotenuse, according to the Pythagorean theorem. In this situation, we can write:

2.2360679775² + 5² = 5.47722557505²

When we simplify and solve for one of the variables, we get:

5² = 5.47722557505² - 2.2360679775²

25 = 24.9999999999971

Step-by-step explanation:

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 perimeter of the rhombus is 20 inches, and the area is 24 square inches.

How to solve the question?

To find the perimeter of a rhombus, we need to know the length of one side. Fortunately, we can use the properties of a rhombus to find the length of the sides. A rhombus has two pairs of equal-length sides, so we can use the Pythagorean theorem to find the length of each side.

Let's label the diagonals of the rhombus as d1 and d2. The diagonals of a rhombus bisect each other at right angles, so we can draw a right triangle with half of each diagonal as the legs and a side of the rhombus as the hypotenuse. Using the Pythagorean theorem, we can find the length of the sides:

(1/2)d1 = 3 inches

(1/2)d2 = 4 inches

Side length = √((1/2)d1² + (1/2)d2²) = √(9 + 16) = 5 inches

Now that we know the length of the sides, we can find the perimeter:

Perimeter = 4 x side length = 4 x 5 = 20 inches

To find the area of the rhombus, we can use the formula:

Area = (diagonal 1 x diagonal 2) / 2

Area = (6 x 8) / 2 = 24 square inches

So the perimeter of the rhombus is 20 inches, and the area is 24 square inches.

The value of x is 65. Please note that this solution is based on the assumption that the angles QRP and PSQ are supplementary. If this assumption doesn't hold, feel free to let me know.

We need to find the value of x in the equation ZQRP = (2x + 20)° given that ZPSQ = 30°. Since the question doesn't provide enough information about the relationship between angles QRP and PSQ, I'll assume that they are supplementary angles (angles that add up to 180°). This assumption is based on the possibility that the angles form a straight line or a linear pair.

If angles QRP and PSQ are supplementary, their sum is 180°:

(2x + 20)° + 30° = 180°

Now, we can solve for x:

2x + 50 = 180

Subtract 50 from both sides:

2x = 130

Also recall that the formula for the area of a circle is:

[tex]\pi r^2[/tex]

Both formulas use the radius; one squares it, while the other doubles it.

Let's start by turning the formula for the circumference of a circle into the formula for the area of a circle. We start off with:

[tex]2\pi r[/tex]

We want to square the radius, but we can't do that without squaring everything else, too, so let's get rid of the other terms.

Divide the circumference by [tex]2\pi[/tex]:

Now, we can square r:

[tex]r\\r^2[/tex]

Now, all we have to do is multiply by pi:
