Answer:

the dependent variable is distance (option B)

Explanation:

Given:

The speed of a car = 45 miles per hour

To find:

the dependent variable

Dependent variable are variables which depend on another quantity

from the options:

a) 45 is not a variable but a constant

b) speed = distance/time

distance depends on time. A faster or lower time time will affect the distance covered

c) The car is not a variable

d) the time is an independent variable

Hence, the dependent variable is distance (option B)

The equation of the line containing the paints A and B is y = -1/3x + 4

from the question, we have the following parameters that can be used in our computation:

Answer:

Step-by-step explanation:

To differentiate the function y = x^4 - x, we will use the power rule of differentiation. The power rule states that if f(x) = x^n, then the derivative of f(x) is f'(x) = nx^(n-1).

So, for y = x^4 - x, we can find the derivative as follows:

y' = 4x^3 - 1

So, the derivative of the function y = x^4 - x is y' = 4x^3 - 1.

Answer and Step-by-step explanation:

The real line is the line whose points are real numbers. The symbol used for the entire line is R.                

A point is chosen on line as the origin. Points are right or positive, and points to the left are negative.

The main properties of real numbers are commutative, Associative, and Distributive. Real numbers are closed, have an identity element, additive inverse, multiplicative inverse, and zero product. When we choose a uniform random number, it should satisfy all these conditions of real numbers.

Choose a random number on the real line; for example, when we choose zero (0), it does not satisfy the multiplicative inverse.

Multiplicative inverse is a x 1/a = 1, but for 0, 1/0 it is undefined.

Hence it is not possible for a  random number from the whole real line.

Answer:

\(B(x,y) = (-2,-4)\)

\(O(x,y) = (6,-6)\)

\(Y(x,y) = (13,1)\)

Step-by-step explanation:

Given

\(Translation: (-3,6)\)

\(B': (-5,2)\)

\(O':(3,0)\)

\(Y': (10,7)\)

Required

Determine the coordinates of B, O and Y

Recall that the given translation is:

\((x,y) = (-3,6)\)

Calculating the x coordinates of B:

\(B_x + x = B'_x\)

Where \(B': (-5,2)\)

This gives

\(B_x -3 = -5\)

\(B_x = -5 + 3\)

\(B_x = -2\)

Calculating the y coordinates of B:

\(B_y + y = B'_y\)

This gives

\(B_y + 6 = 2\)

\(B_y = 2 - 6\)

\(B_y = -4\)

Hence:

\(B(x,y) = (-2,-4)\)

Calculating the x coordinates of O:

\(O_x + x = O'_x\)

Where \(O':(3,0)\)

This gives

\(O_x -3 = 3\)

\(O_x = 3 + 3\)

\(O_x = 6\)

Calculating the y coordinates of O:

\(O_y + y = O'_y\)

This gives

\(O_y + 6 = 0\)

\(O_y = 0 - 6\)

\(O_y = - 6\)

Hence:

\(O(x,y) = (6,-6)\)

Calculating the x coordinates of Y:

\(Y_x + x = Y'_x\)

Where \(Y': (10,7)\)

This gives

\(Y_x -3 = 10\)

\(Y_x = 10 + 3\)

\(Y_x = 13\)

Calculating the y coordinates of Y:

\(Y_y + y = Y'_y\)

This gives

\(Y_y + 6 = 7\)

\(Y_y = 7 - 6\)

\(Y_y = 1\)

Hence:

\(Y(x,y) = (13,1)\)

Answer:

From the given information, we know that:

The thousands digit is greater than 6 and less than 8, so it must be 7.

The hundreds digit is the highest even number, so it must be 8.

The tens digit is 6.

The sum of the tens and ones digit is equal to the hundreds digit, so 6 + ones digit = 8.

Solving for the ones digit, we get:

ones digit = 8 - 6 = 2

Putting the digits together, we get the number: 7862.

So, the 4-digit number that satisfies all the given conditions is 7862.

Step-by-step explanation:

Given the clues, the thousands digit is 7, the hundreds digit is 8, the tens digit is 6, and the ones digit is 2; therefore, the 4-digit number is 7862.

Given the hints, we can infer that:

Therefore, the 4-digit number is 7862.

The annualized return for the entire period is the closest to 10.5%.

To calculate the annualized return for the entire period, we need to consider the returns for each year and the return in the first quarter of Year 4. Since the returns are given for each period, we can use the geometric mean to calculate the annualized return.

The formula for calculating the geometric mean return is:

Geometric Mean Return = [(1 + R1) * (1 + R2) * (1 + R3) * (1 + R4)]^(1/n) - 1

Where R1, R2, R3, and R4 are the returns for each respective period, and n is the number of periods.

Given the returns:

Year 1 return: 5% or 0.05

Year 2 return: 12% or 0.12

Year 3 return: -6% or -0.06

First quarter of Year 4 return: 2% or 0.02

Using the formula, we can calculate the annualized return:

Annualized Return = [(1 + 0.05) * (1 + 0.12) * (1 - 0.06) * (1 + 0.02)]^(1/3) - 1

Annualized Return = (1.05 * 1.12 * 0.94 * 1.02)^(1/3) - 1

Annualized Return = 1.121485^(1/3) - 1

Annualized Return ≈ 0.105 or 10.5%

Therefore, the annualized return for the entire period is approximately 10.5%.

Based on the histograms, it appears that Los Angeles has a higher typical temperature than New York City during the summer month.

In statistics, a distribution is a way of showing how data is spread out or arranged. It describes the pattern of values in a dataset, and provides information on the frequency, range, and possible values of the data.

A distribution can take many forms, depending on the type of data being analyzed. For example, a distribution can be:

Symmetrical: where the data is evenly distributed around a central value, such as a normal distribution.

Skewed: where the data is not evenly distributed and is clustered more towards one end of the range than the other end, such as a positively skewed distribution.

Bimodal: where there are two distinct peaks in the data, such as in a distribution of test scores for a class with both high-performing and low-performing students.

There are many ways to represent a distribution, but some common methods include histograms, box plots, and probability density functions.

Understanding the distribution of data is important in statistics because it can help identify patterns, trends, and outliers in the data. It can also help inform decisions about which statistical methods to use when analyzing the data.

Here,

In the Los Angeles histogram, the peak of the distribution is around 80 degrees Fahrenheit, whereas in the New York City histogram, the peak is around 75 degrees Fahrenheit. However, the New York City histogram appears to have more variation in temperature than the Los Angeles histogram. This can be seen in the wider spread of the distribution, with a range of temperatures from around 65 to 95 degrees Fahrenheit, compared to the narrower range of temperatures in the Los Angeles distribution, which ranges from around 70 to 90 degrees Fahrenheit.

In other words, while the typical temperature in Los Angeles during the summer month is higher than in New York City, the temperature in New York City varies more widely from day to day.

To show that the point (å, ä) is on the perpendicular bisector of the line segment with endpoints (Ů, ü) and (ĝ, ġ), we need to demonstrate two things: that the point lies on the line segment, and that it is equidistant from the endpoints.

1. Determine the midpoint of the line segment:

  - The midpoint coordinates (\(x_{mid, y_{mid\)) can be found using the midpoint formula:

    \(x_{mid\) = (x1 + x2) / 2 and \(y_mid\) = (y1 + y2) / 2, where (x1, y1) and (x2, y2) are the coordinates of the endpoints.

    In this case, we have (x1, y1) = (Ů, ü) and (x2, y2) = (ĝ, ġ).

2. Calculate the midpoint coordinates:

  - Substitute the values into the midpoint formula to find (x_mid, y_mid).

3. Find the slope of the line segment:

  - Use the slope formula: slope = (y2 - y1) / (x2 - x1).

    Apply the formula to the endpoints (Ů, ü) and (ĝ, ġ) to determine the slope of the line segment.

4. Determine the negative reciprocal of the line segment's slope:

  - Take the negative reciprocal of the slope calculated in the previous step. The negative reciprocal of a slope m is -1/m.

5. Write the equation of the perpendicular bisector:

  - Using the negative reciprocal slope and the midpoint coordinates (\(x_{mid\), \(y_{mid\)), write the equation of the perpendicular bisector in point-slope form: y - \(y_{mid\) = \(m_{perp\) * (x - \(x_{mid\)), where \(m_{perp\) is the negative reciprocal slope.

6. Substitute the point (å, ä) into the equation:

  - Replace x and y in the equation of the perpendicular bisector with the coordinates of the point (å, ä). Simplify the equation.

7. Verify that the equation holds true:

  - If the equation is satisfied when substituting (å, ä), then the point lies on the perpendicular bisector.

By following these steps, you can demonstrate that the point (å, ä) lies on the perpendicular bisector of the line segment with endpoints (Ů, ü) and (ĝ, ġ).

The total cost of the pita bread and hummus dips will be $305.00.

To determine the cost of the pita bread and hummus dips, Toula can use the following expressions:

Cost of pita bread:

Number of crates needed = (150 bags) / (50 bags/crate) = 3 crates

Cost of each crate = $15.00

Total cost of pita bread = (Number of crates needed) × (Cost of each crate) = 3 crates × $15.00/crate = $45.00

Cost of hummus dips:

Number of boxes needed = (65 containers) / (5 containers/box) = 13 boxes

Cost of each box = $20.00

Total cost of hummus dips = (Number of boxes needed) × (Cost of each box) = 13 boxes × $20.00/box = $260.00

Therefore, the expressions Toula can use to determine the costs are:

Cost of pita bread = 3 crates × $15.00/crate

Cost of hummus dips = 13 boxes × $20.00/box

The total cost will be the sum of the costs of pita bread and hummus dips:

Total cost = Cost of pita bread + Cost of hummus dips

Total cost = $45.00 + $260.00

Total cost = $305.00

Therefore, the total cost of the pita bread and hummus dips will be $305.00.
