The percent of the box that will remain unwrapped by the 60 square feet of paper is about 20.70%

A percentage is a proportion of a number expressed as fraction of a 100

The dimensions in mixed fractions can be expressed as follows;

Height of the box = 1 2/3 feet = 5/3 feet

Width of the box = 4 feet

Length of the box = 5 1/2 feet = 11/2 feet

Surface area of the box, A = 2 × (5/3) × 4 + 2 × 4 × 11/2 + 2 × (5/3) × 11/2 = 227/3 = 75 2/3 square inches

The percent of the box that will remain unwrapped is therefore;

Percentage = 60/(227/3) × 100 ≈ 79.3%

The percentage of the box that will remain unwrapped is about (100 - 79.3)% = 20.70%

The probabilities are as follows:

(a) P(A')= 0.7

(b) P(A∪B) =  0.3

(c) P(A'∩B) =  0

(d) P(A∩B') =  0.1

(e) P[(A∪B)'] =  0.7

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.

(a) P(A') = 1 - P(A) = 1 - 0.3 = 0.7

(b) P(A∪B) = P(A) + P(B) - P(A∩B) = 0.3 + 0.2 - 0.2 = 0.3

(c) P(A'∩B) = P(B) - P(A∩B) = 0.2 - 0.2 = 0

(d) P(A∩B') = P(A) - P(A∩B) = 0.3 - 0.2 = 0.1

(e) P[(A∪B)'] = 1 - P(A∪B) = 1 - 0.3 = 0.7

Note: P(A) represents the probability of event A occurring, P(B) represents the probability of event B occurring, and P(A∩B) represents the probability of both events A and B occurring simultaneously. The symbol '∪' represents the union of two events, and the symbol '∩' represents the intersection of two events. The complement of an event A is represented by A'.

The plane degrees off course is 6.79 degrees off at a speed of 541. 92 km / hr relative to the ground.

To find the airplane's course deviation and its ground speed, we need to first determine the velocity vectors of the airplane and the wind.

W x = W x cos(225) = 90 x cos(225) = -63.64 km/hr

Wy = W x sin(225) = 90 x sin(225) = -63.64 km/hr

Magnitude: |R| = sqrt(Rx^2 + Ry^2) = √(536.36^2 + (-63.64)^2) = 541.92 km/hr

Direction: θ = arctan(Ry / Rx) ≈ arctan (-63.64 / 536.36) = -6.79 degrees

The answer of the given question based on the graph is ,  The locations of A′ and B′ are A′ (0, 1) and B′ (1, 0); lines f and f′ are parallel.

A scale factor is a number that scales, or multiplies, a quantity by some factor. It is used in mathematics to describe the relationship between corresponding measurements of two similar figures, such as triangles or rectangles.

To dilate line f by scale factor of one half with center of dilation at origin, we  multiply coordinates of each point on line f by 1/2.

The equation of line f can be found by using the points A and B:

slope of line f = (0 - 2)/(2 - 0) = -1

y-intercept of line f = 2

Therefore, the equation of line f is y = -x + 2.

To find the coordinates of A' and B' after dilation, we can apply the dilation factor to each point:

A' = (0, 2)*1/2 =(0, 1)

B' = (2, 0)*1/2 =(1, 0)

So A' is located at (0, 1) and B' is located at (1, 0) after dilation.

Now let's analyze the relationship between lines f and f'. The dilation was centered at the origin, so the origin is a fixed point of the dilation. This means that the point where lines f and f' intersect must be the origin.

If we plug in x = 0 into the equation of line f, we get y = 2. This means that point A is located at (0, 2) and intersects with line f at y = 2. After dilation, point A' is located at (0, 1), which means that lines f and f' intersect at point A.

To determine the relationship between lines f and f', we can compare their equations. The equation of f' can be found by using the points A' and B':

slope of f' = (0 - 1)/(1 - 0) = -1

y-intercept of f' = 0

Therefore, the equation of f' is y = -x.

Comparing the equations of f and f', we can see that they have the same slope of -1, which means they are parallel. Therefore, the correct answer is: The locations of A′ and B′ are A′ (0, 1) and B′ (1, 0); lines f and f′ are parallel.

Emily's situation can be represented by the linear-equation in y =  [tex]\frac{-1}{10}[/tex]x + 15, where 'x' represents the time in seconds & 'y' represents the number of steps.

What is linear-equation?

An equation is linear if the maximum power or the degree of equation or of the variable is 1. The equation forms a straight line on the graph. A linear equation in one variable has the general or standard form mx + b = 0, where'm' stands for the slope and 'b' for the intercept.

To form a linear equation using points on the graph, we can use the general form as y=mx+b or [tex]\frac{Y-Y1}{X-X1}[/tex] =[tex]\frac{Y2-Y1}{X2-X1}[/tex]

The y intercept(b), is 15 as the linear graph intersects y-axis at (0,15)

b=15

For slope m, we can use point (150,0)

Substituting coordinates of point in equation y = mx + b

y = mx + b

0 =m(150) + 15

0 = 150m + 15

150m = -15

m = [tex]\frac{-15}{150}[/tex]

m = [tex]\frac{-1}{10}[/tex]

Using the slope & intercept to form equation:

y =  [tex]\frac{-1}{10}[/tex]x + 15

The speed of the boat in still water is 15 mi/hr while the speed of the current is 10 mi/hr.

Step-by-step explanation:

Given: d = 350 miles

[tex]t_{ds}[/tex] = 14 hours

[tex]t_{us}[/tex] = 70 hours

Asked: Speed of the boat [tex]V_b[/tex] in still water and speed of the current [tex]V_c[/tex]

Solve:

Note that when the boat is going downstream, the current is helping the boat to speed up and when the boat is going upstream, the current is slowing it down.

Get the speed downstream

[tex]V_{ds} = V_b + V_c[/tex]

350mi/14hrs = [tex]V_b + V_c[/tex]

25 mi/hr =    [tex]V_b + V_c[/tex]  

Transpose to get the value of Vb

25 mi/hr - Vc = Vb   ---equation 1

Get the speed upstream

[tex]V_{us} = V_b - V_c[/tex]

350mi/70hrs = Vb - Vc

5 mi/hr = Vb - Vc

Transpose to get the value of Vb

5 mi/hr + Vc = Vb   ----equation 2

Equate equations 1 and 2

25 mi/hr - Vc = 5 mi/hr + Vc

Transpose

25 mi/hr - 5 mi/hr = Vc + Vc

20 mi/hr = 2 Vc

Divide both sides of the equation by 2

10 mi/hr = Vc

Vc = 10 mi/hr

From 25 mi/hr =    [tex]V_b + V_c[/tex]  we then solve the speed of the boat

25 mi/hr = Vb + 10 mi/hr

25 mi/hr - 10 mi/hr = Vb

15 mi/hr = Vb

Vb = 15 mi/hr

The answer of the given question based on the variance is , 92% confidence that the true population mean lies between 69.11 and 74.89.

In statistics, the mean is a measure of central tendency that represents the average of a set of numerical data. It is also known as the arithmetic mean or simply the average. The mean is calculated by adding up all the values in the dataset and then dividing the sum by the number of values.

To construct a random interval with a 0.92 confidence level, we need to find the corresponding z-score for the level of confidence. Since the interval is not two-sided, we will use a one-tailed z-score.

Using a standard normal distribution table or calculator, we find that the z-score corresponding to a 0.92 confidence level is approximately 1.41.

To find the 92% confidence interval for the population mean, we can use the following formula:

CI = ₓ⁻ ± zα/2 * σ/√n

where ₓ⁻ is the sample mean, σ is the population standard deviation (unknown in this case), n is the sample size, and zα/2 is  critical value of  standard normal distribution corresponding to desired level of confidence.

Substituting the given values, we get:

CI = 72 ± 1.41 * (4 / √20)

CI = (69.11, 74.89)

Therefore, we can say with 92% confidence that the true population mean lies between 69.11 and 74.89.

To the nearest block, Landon's house is at distance of 12 blocks away from Maria's house if Maria could walk in a straight line.

A basic mathematical theorem relating to the sides of a right-angled triangle is known as Pythagoras' theorem. The square of the length of the hypotenuse, the side that faces the right angle, is said to be equal to the sum of the squares of the lengths of the other two sides, known as the legs, in a right triangle.

This can be written in mathematical notation as:

c² = a² + b²

where c is the length of the hypotenuse, and a and b are the lengths of the legs of the right triangle.

In this case, we can consider the straight line between Maria's house and Landon's house as the hypotenuse of a right triangle, with the distances they walked as the other two sides. We can use the distance formula to find the lengths of those sides:

Distance walked by Maria = √(9² + 3²) = √90 ≈ 9.49 blocks

Distance walked by Landon = √(5² + 7²) = √74 ≈ 8.60 blocks
