8) The percent of people that said that Pinocchio was their favorite Disney Movie is of: 28%.

9) The percent of people that said that Pinocchio or Cars was their favorite Disney movie is of: 39%.

10) The two movies that about half the people say were their favorite is of: Pinocchio and Toy Story.

From the pizza graph, the sum of all the percentages must be of 100%, hence the Pinocchio percentage is obtained as follows:

10 + 11 + 14 + 15 + 22 + P = 100

72 + P = 100

P = 100 - 72

P = 28%.

Then the percentage for Pinocchio or Cars is of:

28 + 11 = 39%.

The percentage for Pinocchio or Toy Story is of:

28 + 22 = 50%.

(about half).

Time is considered to be the dimension on which any system evolves.

9.2 seconds will take for him to strike the ground.

Time can be thought of as the dimension in which the evolution of every system occurs.

It can be calculated using the following units: seconds, minutes, hours, days, weeks, months, and years.

Given,

h = 45m

g = -9.8m/s

Solution:

Vi = 0

h = Vi t + 1/2gt^2

Since Vi is 0

2h = gt^2

t^2 = 2h/g

t = \(\sqrt{2h/g}\)

\(t =\sqrt{2 * -45/-9.8}\)

The complete table when Noah is running a marathon at a constant speed of 6 miles per hour is mentioned below:

Time                 Distance

 1                           6

 1/2                        3

 \(1\frac{1}{3}\)                         8

 \(1\frac{1}{2}\)                         9

  9                        54

 \(4\frac{1}{2}\)                        27

The running speed of Noah is 6 mph.

The formula for distance is given as:

D = v × t

Where D is the distance, v is the speed and t is the time.

Now,

When t = 1 hour,

D = 6 × 1 = 6 miles

When t = 1/2hour,

D = 6 × 1/2 = 3 miles

When t = \(1\frac{1}{3}\) hour,

D = 6 × \(1\frac{1}{3}\) = 6 × 4/3 = 8 miles

When t = \(1\frac{1}{2}\) hour,

D = 6 × \(1\frac{1}{2}\) = 6 × 3/2 = 9 miles

When t = 9 hours,

D = 6 × 9 = 54 miles

When t = \(4\frac{1}{2}\) hour,

D = 6 × \(4\frac{1}{2}\) = 6 × 9/2 = 27 miles

Therefore, the table will be:

Answer:

Step-by-step explanation:

it is complating squer method that used for solving x in a quadratic equetion . in this step you will add

(y/2)^2 if y is the cofitient of x .

The standard deviation of the given data can be calculated using the formula for the population standard deviation:

Standard deviation = √[∑(X - μ)² * f / N]

where X is the data value, μ is the mean, f is the frequency, and N is the total number of observations.

Given the data:

X: 3 4 5 6 7 8 9

f: 37 8 10 12 4 3 2

Assumed mean (μ) = 6

To calculate the standard deviation, we need to calculate the squared difference between each data value and the mean, multiply it by the frequency, and sum up these values. Then divide the sum by the total number of observations (N) and take the square root of the result.

Let's calculate it step by step:

(X - μ)² * f:

(3 - 6)² * 37 = 111

(4 - 6)² * 8 = 32

(5 - 6)² * 10 = 10

(6 - 6)² * 12 = 0

(7 - 6)² * 4 = 4

(8 - 6)² * 3 = 12

(9 - 6)² * 2 = 18

Sum of (X - μ)² * f = 187

Now divide the sum by the total number of observations (N = 37 + 8 + 10 + 12 + 4 + 3 + 2 = 76) and take the square root of the result:

Standard deviation = √(187 / 76) ≈ 1.82

Therefore, the standard deviation of the given data is approximately 1.82.

Finally, we can simplify by combining like terms and expressing the answer using positive exponents only: g'(x) = 32x³(2x⁴ + 9)(x⁹ − 21x⁷ + 147x⁵ − 343x³ + 343x) + (2x⁴ + 9)²(117882x² - 588x³ + 686x)².

In calculus, the derivative is a mathematical concept that describes how a function changes as its input (also known as the independent variable) changes. It measures the rate at which the function is changing at a specific point, which is the slope of the tangent line to the curve of the function at that point. The derivative of a function f(x) is denoted as f'(x) or df(x)/dx and represents the instantaneous rate of change of the function with respect to its input x. The derivative can be used to find the maximum and minimum values of a function, to calculate the slope of a curve, and to solve optimization problems in various fields such as physics, engineering, and economics.

Here,

We will use the chain rule and product rule to find the derivative of the function g(x) = (2x⁴ + 9)²(x³ − 7x)³:

g(x) = (2x⁴ + 9)² (x³ − 7x)³

g'(x) = 2(2x⁴ + 9)¹(8x³)(x³ − 7x)³ + (2x⁴ + 9)²(3x²-7)(3x²-7x)²

Simplifying this expression gives:

g'(x) = 16x³(2x⁴ + 9)(x³ − 7x)³ + (2x⁴ + 9)²(3x²-7)(3x²-7x)²

We can further simplify this expression by distributing the factors and combining like terms:

g'(x) = 32x³(2x⁴ + 9)(x⁹ − 21x⁷ + 147x⁵ − 343x³ + 343x) + (2x⁴ + 9)²(117882x² - 588x³ + 686x)²

The bag that contains​ pennies, nickels,​ dimes, and quarters have the total amount of 5.26 dollars.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

A bag contains 50 coins

Now, Number of pennies = 14% of 50

                               = 0.14 × 50

                               = 7 pennies

and, Number of dimes  = 40% of 50

                             = 0.40 × 50

                             = 20 dimes

Number of nickels = 6 more than pennies

                              = 6 + 7

                             = 13 nickles

Number of quarters = Rest of the coins

                               = 50 - (7 + 20 + 13)

                               = 50 - 40

                              = 10 quarters

As we know,

1 penny = 0.01 dollar

7 pennies = 0.01 ×7  = 0.07 dollar

1 dime = 0.10 dollar

20 dimes = 0.10 × 20 = 2.00 dollar

1 nickel = 0.05 dollar

13 nickel = 0.05 × 13 = 0.65 dollar

1 quarter = 0.25 dollar

10 quarter = 0.25 × 10 = 2.50 dollars

Total value of the coins in the bag = 0.07 + 2.00 + 0.65 + 2.50

                                                           = 5.22 dollars

Explanation:

Multiply both sides by 2 to clear out the fraction

y = (1/2)x+4

2y = 2[ (1/2)x + 4 ]

2y = 2*(1/2)x + 2*4

2y = x + 8

Then move the x term over to the left side

2y = x+8

2y-x = 8

-x+2y = 8

Optionally we can multiply both sides by -1

-x+2y = 8

-1*(-x+2y) = -1*8

x-2y = -8

This is in standard form Ax+By = C with A = 1, B = -2, C = -8

The reason why I multiplied both sides by -1 was to make A > 0 which is what some textbooks use as convention. Of course -x+2y = 8 is equally valid too.

To predict a linear regression score, you first need to train a linear regression model using a set of training data.

Once the model is trained, you can use it to make predictions on new data points. The predicted score will be based on the linear relationship between the input variables and the target variable,

A higher regression score indicates a better fit, while a lower score indicates a poorer fit.

To predict a linear regression score, follow these steps:

1. Gather your data: Collect the data p

points (x, y) for the variable you want to predict (y) based on the input variable (x).

2. Calculate the means: Find the mean of the x values (x) and the mean of the y values (y).

3. Calculate the slope (b1): Use the formula b1 = Σ[(xi - x)(yi - y)]  Σ(xi - x)^2, where xi and yi are the individual data points, and x and y are the means of x and y, respectively.

4. Calculate the intercept (b0): Use the formula b0 = y - b1 * x, where y is the mean of the y values and x is the mean of the x values.

5. Form the linear equation: The linear equation will be in the form y = b0 + b1 * x, where y is the predicted value, x is the input variable, and b0 and b1 are the intercept and slope, respectively.

6. Predict the linear regression score: Use the linear equation to predict the value of y for any given value of x by plugging the x value into the equation. The resulting y value is your predicted linear regression score.

Answer:

The conclusion supported by the diagram is;

(A)  \(\dfrac{AB}{BC} = \dfrac{FE}{ED}\)

Step-by-step explanation:

The question is examines the theorem that two transversals cut by three or more parallel lines are proportionally divided by the transversals

The given parallel lines are;

Line CD, line BE, and line line AB

The given transversals are;

Line AC and line DF

Therefore, by the above three or more parallel lines cutting two transversal theorem, we have;

BC/AB = ED/FE, BC/DF = AB/FE, CA/AB = DF/FE

From BC/AB = ED/FE, we find the inverse of both sides to get;

\(\dfrac{1}{\dfrac{BC}{AB} } = \dfrac{1}{\dfrac{ED}{FE} }\)

\(\dfrac{1}{\dfrac{BC}{AB} } = \dfrac{AB}{BC} \ and \ \dfrac{1}{\dfrac{ED}{FE} } = \dfrac{FE}{ED}\)

\(\therefore \ \dfrac{AB}{BC} = \dfrac{FE}{ED}\)

The correct option is \(\dfrac{AB}{BC} = \dfrac{FE}{ED}\)
