The shipping charge of an item on the purchase $56 is $2.52.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

The percentage of a number is the value of the number out of 100.

For example, in a class, there are 26 boys and 24 girls. So, the percentage of boys in the class is 26/(26+24) × 100 = 26/50 × 100 = 52%, which means out of 100, 52 are boys.

A company charges  shipping fee = 4.5% of the purchase price for all items,

Cost of an item =$56

So, shipping fee = 4.5% of 56

= 4.5/100 × 56

= 0.045 × 56

= $2.52

The relationship between and in terms of equation is linear model

In statistics, linear relationships are often studied as they provide a simple way to model data. However, not all relationships between variables can be accurately represented using a linear model. In such cases, transforming the variables can sometimes reveal a nonlinear relationship.

When we say we have found a linear relationship between two variables, it means that one variable can be expressed as a linear function of the other.

If we have two variables x and y, a linear relationship between them would be of the form y = mx + b, where m is the slope of the line and b is the y-intercept. This means that as x increases or decreases, y changes in a straight-line fashion.

To find the nonlinear relationship between the original variables, we need to invert the transformation. In this case, we can express y in terms of x by using the inverse of the transformation we applied. Let's say we applied a transformation of the form y' = log(y) and x' = log(x), then we can invert this transformation by taking the exponential of both sides of the equation, giving us

=> [tex]y = e{y'}[/tex] and [tex]x = e^{(x').}[/tex]

Using these equations, we can express the linear model in terms of the original variables as

=> [tex]y = e^{(mx' + b)}[/tex]

Therefore, the relationship between y and x in terms of e and the rounded numerical value is given by

=> [tex]y = e^{(mx' + b)}[/tex]

where m and b are the slope and intercept of the linear model.

The probability of the shuttle launching safely under similar conditions is 0.859, or approximately 86%.

Scientists and statisticians played a crucial role in analyzing the cause of the disaster, which was eventually attributed to the failure of O-ring joints in the shuttle's booster rockets.

To understand the probability of the shuttle launching safely under similar conditions, we need to consider the probability of all six O-ring joints functioning properly. According to experts, the probability of an individual O-ring joint working in cold conditions was 0.977.

Assuming that the O-ring joints succeed or fail independently, we can use the multiplication rule of probability to calculate the probability of all six joints functioning properly.

The multiplication rule states that the probability of two independent events occurring together is the product of their individual probabilities. In this case, the probability of all six joints working properly is:

P(all six joints work) = P(joint 1 works) x P(joint 2 works) x P(joint 3 works) x P(joint 4 works) x P(joint 5 works) x P(joint 6 works)

Plugging in the given probability of an individual O-ring joint working in cold conditions (0.977), we get:

P(all six joints work) = 0.977 x 0.977 x 0.977 x 0.977 x 0.977 x 0.977

P(all six joints work) = 0.977⁶

The length of Mr. Neil's homeroom is (10/11) times the length of Miss Robert's homeroom.

The length of Mr. Neil's homeroom is calculated as follows:

Let's assume that Miss Robert's homeroom has width w and length l, and Mr. Neil's homeroom has width (1¹/₁₀ or 11/10)w and length x.

Both homerooms have the same perimeter, therefore:

2w + 2l = 2(11/10)w + 2x

Simplifying the equation:

2l - 2x = (2/10)w

l - x = (1/10)w

x = l - (1/10)w

To solve for x, we need to express it in terms of l and w.

From the equation above, we can substitute x with l - (1/10)w:

(11/10)w = 2l - x

(11/10)w = 2l - l + (1/10)w

(10/10)w = l + (1/10)w

w = (10/11)l

Substituting w with (10/11)l in the expression for x, we get:

x = l - (1/10)(10/11)l

x = l - (1/11)l

x = (10/11)l

Therefore, the length of Mr. Neil's homeroom is (10/11) times the length of Miss Robert's homeroom.

The fraction that is the ratio of the shaded area of the circle to the area between the two squares is (π−2)/2.

A fraction is a mathematical expression that represents a part or a proportion of a whole.

Let us assume that the radius of the circle is 'r' units. Therefore, the diameter of the circle is 2r units. The diagonal of the inner square is equal to the diameter of the circle, which is 2r units. Hence, the side of the inner square is r√2 units.

Now, let's consider the area of the circle. The formula for the area of a circle is

=>  A=πr².

Therefore, the area of the circle is πr².

The area between the two squares is the difference between the area of the outer square and the area of the inner square. The area of the outer square is

=> (2r)²=4r²,

and the area of the inner square is

=> (r√2)²=2r².

Hence, the area between the two squares is

=> 4r²−2r²=2r².

The shaded area of the circle is the area inside the circle but outside the inner square. We can find this area by subtracting the area of the inner square from the area of the circle. Therefore, the shaded area of the circle is

=> πr²−2r²=(π−2)r².

Now, let's find the ratio of the shaded area of the circle to the area between the two squares. We can express this ratio as a fraction. Thus,

ratio = (π - 2)r² / 2r

We can simplify this fraction by canceling out the common factor r^2 in both the numerator and denominator. Thus,

ratio = (π - 2) / 2

This fraction is closest to the ratio of the shaded area of the circle to the area between the two squares.

Answer:

Step-by-step explanation:

The temperature inside the building when the heat was turned on at 6 am was approximately 57.4 F

To solve this problem, we can use the formula for heat transfer:

Q = mcΔT

where Q is the amount of heat transferred, m is the mass of the air, c is the specific heat of air, and ΔT is the change in temperature.

First, we can calculate the amount of heat lost from the building between 10 pm and 2 am. Assuming the building is a closed system, the amount of heat lost must be equal to the amount of heat gained by the outside environment. We can assume that the mass of air in the building remains constant, and use the specific heat of air at constant volume, which is approximately 0.718 J/g·K.

Q = mcΔT = (m)(0.718)(65-70) = -3.59m

Next, we can calculate the amount of heat gained by the building between 2 am and 6 am. Again, assuming the building is a closed system, the amount of heat gained must be equal to the amount of heat lost by the outside environment. We can assume that the mass of air in the building remains constant, and use the same specific heat of air at constant volume.

Q = mcΔT = (m)(0.718)(T-65)

where T is the temperature inside the building at 6 am. We can set this equal to the heat lost by the outside environment:

Q = -3.59m

Using the average temperature of 45 f for the outside environment, we can calculate the change in temperature between 10 pm and 6 am:

ΔT = (45-70) = -25

So the amount of heat lost by the outside environment is:

Q = mcΔT = (m)(0.718)(-25) = -17.95m

Setting this equal to the heat gained by the building:

(m)(0.718)(T-65) = -17.95m

Simplifying and solving for T, we get:

T = 57.4 F

a) The median is expected to be larger than the mean because the life expectancy of some countries may be much lower than the others, thus affecting the mean. The mean is calculated by adding all the values together and dividing by the number of values, and if there are any values that are much lower or higher than the rest, this will affect the mean significantly. The median, however, is the midpoint of the values, so outliers have less of an influence on it.

b) The median should be reported as it is a better measure of central tendency, as it is not affected by outliers. The median is the midpoint of the values, which means that if there are any values that are much lower or higher than the rest, it will not affect the median as much as it does the mean.

If the sum of two angles is 90 degrees, then the angles are called complementary angles.

Complementary angles are a type of angle relationship where two angles add up to exactly 90 degrees. In other words, when you add the measures of two complementary angles together, the sum is always equal to 90 degrees.

For example, if angle A measures 30 degrees, and angle B measures 60 degrees, then angle A and angle B are complementary angles, because 30 degrees + 60 degrees = 90 degrees.

Complementary angles are important in geometry and trigonometry, because they often appear in problems involving right triangles. In a right triangle, one of the angles measures 90 degrees, which means that the other two angles must be complementary.

For example, if one angle in a right triangle measures 30 degrees, then the other angle must measure 60 degrees, since 30 degrees + 60 degrees = 90 degrees.

Understanding complementary angles can be useful in a wide range of mathematical and real-world contexts. For example, in construction or engineering, understanding complementary angles can help ensure that structures are built at the correct angle to provide the necessary support and stability.
