The required statistical parameters has been computed as follows:

Range = 17.

Standard deviation, SD = 6.87.

Mathematically, the range of a data set can be calculated by using this formula;

Range = Highest number - Lowest number

Range = 25 - 8

Range = 17.

Mathematically, the mean for these set of data would be calculated by using this formula:

Mean = [F(x)]/n

F(x) = 11 + 8 + 5 + 11 + 25

F(x) = 60.

Mean = 60/5

Mean = 12

Next, we would calculate the standard deviation by using this formula:

SD = √(1/n × ∑(xi - u₁)²)

SD = √(1/5 × (11 - 12)² + (8 - 12)² + (5 - 12)² + (11 - 12)² + (25 - 12)²)

SD = √(1/5 × (1 + 16 + 49 + 1 + 169)

Step-by-step explanation:

Rolle's theorem states that if a function f is continuous on the closed interval [a, b] and differentiable on the open interval (a, b) such that f(a) = f(b), then f′(x) = 0 for some x with a ≤ x ≤ b.

The function is not differentiable over [0, 2]. Therefore, the option B is the correct answer.

Rolle's theorem states that if a function f is continuous on the closed interval [a, b] and differentiable on the open interval (a, b) such that f(a) = f(b), then f′(x) = 0 for some x with a ≤ x ≤ b.

The given function is f(x)=x³/3 over [0, 2].

Here, f(0)= 2 and f(2)=2. Hence, according to the Rolle's theorem there should be at least one x for which f'(x)=0.

Now, f'(x)= 3x²/3

0=3x²/3

The distance between two cities, A and B is 1884 miles. The solution has been obtained using the concept of arc of circle.

What is arc of circle?

A circle's arc is referred to as a section or portion of its circumference. A chord of a circle is a straight line that can be created by joining the arc's two ends. A semicircular arc is one whose length is exactly half that of the circle.

We are given that the angle is 27° and radius is 4000 miles

We know that circumference of circle = 2πr

So,

C=2*3.14*4000

C= 25120

Now, to find the length of arc AB,

⇒Arc length = (27° × 25120)/360°

⇒Arc length = 1884

The simple interest rate for Mikhail's investment to grow to $11,500.00 in 20 years is solved to be 10.13%

The rate for the simple interest tis calculated using the formula for simple interest.

The formula is stated as

Simple interest = Principal *  time *  rate / 100

In the problem the give data include

principal = $3,800.00

rate = ?

time = 20 years

simple interest =  $11,500.00 - $3,800.00 = $7700

plugging in the values

Simple interest = Principal *  time *  rate / 100

7700 = 3800 * 20 * r / 100

7700 * 100 = 3800 * 20 * r

In the given expression, t-2 (t+5) is incorrect. The correct expression is (t-2)(t+5) = t² + 3t - 10. The error in the original expression is that it is not using the distributive property. The correct way to find the product is by using either distributive property or FOIL method.

The expression (t-2)(t+5) is the product of two binomials. To find the product, we use the distributive property and the FOIL method. The distributive property states that for any two binomials (a+b)(c+d) = ac + ad + bc + bd.

The FOIL method stands for "first, outer, inner, last", and is a mnemonic for the distributive property. To use the FOIL method, we take the first term from the first binomial, the second term from the second binomial, the second term from the first binomial, and the last term from the second binomial.

In your original expression, the error is that there is no operator between the two binomials (t-2) and (t+5), which makes it unclear whether you are trying to multiply them or not. To correct this, you need to add the multiplication operator () between the two binomials, so it becomes (t-2)(t+5).

A quadratic function of roots x' and x'' is defined as follows:

y = a(x - x')(x - x'').

From the graph, the roots of the function are the x-intercepts, which are the values of x for which the graph crosses the x-axis, hence they are given as follows:

x = 2 and x = 4.

Hence:

y = a(x - 2)(x - 4)

y = a(x² - 6x + 8).

In which a is the leading coefficient.

The vertex is at (3,1), meaning that when x = 3, y = 1, hence the leading coefficient a is obtained as follows:

Here we want to expand and simplify the expression below:

First let's expand that, we can rewrite this as:

(3x - 2)² = (3x - 2)*(3x - 2)

We can distribute that product to get:

(3x - 2)*(3x - 2) = (3x)*(3x) + (3x)*(-2) + (-2)*(3x) + (-2)*(-2)

Now we can keep simplifying this to get:

The first thing to note before solving the question is that the sum of the total angles that are in a triangle is 180°.

In this case, it should be noted that the angles that are given are represented by variables. Therefore, we'll add them together and equate them to 180°. This will be:

18x + 7 + 8x + 11 + 6x + 2 = 180

32x + 20 = 180

Collect the like terms

32x = 180 - 20

32x = 160

Divide

x = 160 / 32

x = 5

First angle = 18x + 7

The percentage increase in the average price of the piano is 40%.

What is the percentage increase?

To calculate the percentage increase, we use the following formula:

In this case, the old value is the average price of the piano in 1991 ($12,500), and the new value is the average price of the piano in 2013 ($17,500). So, we can substitute these values into the formula:

Percentage increase = (17,500 - 12,500) / 12,500 x 100 = 40%
