To solve for the degrees of freedom when the sample size is not given, you need to have additional information about the problem. The degrees of freedom (df) represent the number of values in a calculation.

In statistical analyses, it is typically calculated as the difference between the total number of observations and the number of parameters estimated in the model.

If the sample size is not explicitly provided, you can determine the degrees of freedom based on the specific statistical test or analysis being conducted. Each statistical test has its own formula for calculating the degrees of freedom. For example, in a t-test, the degrees of freedom are determined by subtracting 1 from the sample size. In ANOVA (analysis of variance), the degrees of freedom are calculated based on the number of groups and the total number of observations.

Therefore, to solve for the degrees of freedom when the sample size is not given, you need to identify the specific statistical test or analysis being performed and use the corresponding formula to calculate the degrees of freedom.

Answer: C - It has 0 roots

Step-by-step explanation:

Answer:

Choice b:   2 real roots

Step-by-step explanation:

The original equation is:
x² + 6x = -34

Adding 34 to both sides
x² + 6x + 34 = 0

This is a quadratic equation which can be solved by using the quadratic formula

The roots, \(\sf x_1\) and \(\sf x_2\),  of a quadratic equation of the form ax² + bx + c = 0   are given by:

\(\sf x_{1,\:2}=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\)

In the equation given, a = 1, b = 6 and c = 34

So
\(\sf x_{1,\:2}=\dfrac{-6\pm \sqrt{6^2-4\cdot \:1\cdot \left(-34\right)}}{2\cdot \:1}\)

Let's first determine the square root term:

\(\sf \sqrt{6^2-4\cdot \:1\cdot \left(-34\right)}\\\\= \sqrt{6^2+136}\\\\=\sqrt{36+136}\\\\=\sqrt{172}\\\\\)

Therefore the two roots are

\(\sf x_2=\dfrac{-6+\sqrt{172}}{2\cdot \:1}\\\\and\\\\\sf x_1=\dfrac{-6 - \sqrt{172}}{2\cdot \:1}\)

Both these roots are real and different from each other. There is no need to compute.

Imaginary roots happen only when the term under the square root is negative

So answer is b: 2 real roots

The number of parking spaces that the parking lot has is 32 parking spaces.

To start, we must ascertain the parking lot's length designed exclusively for parking spaces. Bearing in mind that 28 feet at one end of each row is left unmarked, this distance is subtracted from the overall parking lot length:

316 feet - 28 feet  = 288 feet

It is now established that the width of each space assigned to a car is equal to nine feet. Consequently, dividing the previously determined length used for parking by the allotted width per car will determine the total number of available parking spaces:

288 feet / 9 feet = 32 parking spaces

Answer:

3. x= 20.1

4. x = 22.0

Step-by-step explanation:

SohCahToa. S= sin, C= cos, T=tan.

o = Opposite (the side on the other side of the given angle, also referred to as theta.)

h = Hypotenuse (the side on the other side of the right angle, represented as the square thing.)

a = Adjacent (side next to the given angle.)

3. We have opposite = x, adjacent = 24. We can use tan (Toa.)

  tan(40º) = x/24         Multiply both sides times 24.

  x = 24*tan(40º)         Put into calculator

  x = 20.1

4. We have adjacent = 12, hypotenuse = x. We can use cos (Cah.)

  cos(57º) = 12/x         Multiply both sides by x

  x*cos(57º) = 12         Divide by cos(57º)

  x = 12/cos(57º)         Put into calculator

  x = 22.0

Answer:

To calculate the surface area and volume of a cylinder, we can use the following formulas:

a) Surface Area of a Cylinder:

The surface area of a cylinder consists of two circles (top and bottom) and the curved surface area.

The formula for the surface area of a cylinder is:

SA = 2πr² + 2πrh

Where:

SA = Surface Area

r = Radius of the base (half the diameter)

h = Height of the cylinder

Given that the diameter is 16 yards, the radius is half of that, so r = 8 yards. The height is 20 yards.

Substituting the values into the formula, we get:

SA = 2π(8)² + 2π(8)(20)

= 2π(64) + 2π(160)

= 128π + 320π

= 448π

So, the surface area of the cylinder is 448π square yards.

b) Volume of a Cylinder:

The formula for the volume of a cylinder is:

V = πr²h

Using the same values for the radius (r = 8 yards) and height (h = 20 yards), we can calculate the volume:

V = π(8)²(20)

= 64π(20)

= 1280π

The volume of the cylinder is 1280π cubic yards.

A bar chart is a graph that shows the differences in frequencies or percentages among categories of a nominal or an ordinal variable.

A bar chart is a commonly used graphical representation to display the distribution of data in different categories. It is particularly useful when working with nominal or ordinal variables, where the categories are distinct and unordered or have a specific order.

In a bar chart, each category is represented by a rectangular bar whose length corresponds to the frequency or percentage associated with that category. The height of the bar represents the magnitude or count of the variable in each category, allowing for easy visual comparison between the categories.

The bars in a bar chart can be arranged horizontally or vertically, depending on the preference or nature of the data. The chart may also include labels or annotations to indicate the category names or additional information.

By examining the lengths or heights of the bars in a bar chart, it becomes easy to identify the categories with the highest or lowest frequencies or percentages, as well as to compare the relative magnitudes among the different categories. This graphical representation aids in visualizing and interpreting the distribution of a nominal or an ordinal variable effectively.

The pollster needs a sample of at least 2401 people to be at least 95% sure that the sample percentage is within one percentage point of p.

A pollster wishes to know the percentage p of people in a population who intend to vote for a particular candidate. How large must a random sample with replacement be to be at least 95% sure that the sample percentage is within one percentage point of P? To solve this problem, we use the following formula: N = [(1.96 / E) * (p * q)] + 1where,N = the required sample size, E = the maximum error (as a decimal),p = the percentage of the population expected to have the property in question, q = 1 - p.

Let us solve this problem step by step. Maximum error can be written as 1% = 0.01. Therefore, E = 0.01.

The pollster wishes to know p, the percentage of people in the population who intend to vote for a particular candidate. Therefore, we can assume p = 0.5 (50% chance of voting for the candidate).q is calculated by subtracting p from 1.q = 1 - p= 1 - 0.5= 0.5.

Plugging the values in the formula: \(N = [(1.96 / E) * (p * q)] + 1= [(1.96 / 0.01) * (0.5 * 0.5)] + 1= 2401\) .

The pollster needs a sample of at least 2401 people to be at least 95% sure that the sample percentage is within one percentage point of p.
