The margin of error can be calculated using the formula:
Margin of error = (upper limit of the confidence interval - lower limit of the confidence interval) / 2

In this case, a margin of error of 9.55 suggests that the sample mean is quite precise, since it's relatively close to the true population mean (which we know to be 52.90).

In this case, the lower limit of the confidence interval is 43.85 and the upper limit is 61.95.
Margin of error = (61.95 - 43.85) / 2
Margin of error = 9.55
Therefore, the margin of error is 9.55. This means that if the sample size were to be repeated, we would expect the sample mean to be within 9.55 units of the true population mean 95% of the time.
It's worth noting that the confidence interval provides a range of values within which we can be reasonably certain that the true population mean lies. The margin of error, on the other hand, gives us an indication of the precision of our estimate. However, if the margin of error were larger, this would indicate that our estimate is less precise and that we need a larger sample size to obtain a more accurate estimate of the population mean.

The probability that the flight will not be delayed is 0.79.

If the probability that a flight will be delayed is 0.21, then the probability that it will not be delayed must be:

Understand that the total probability of an event is always 1. In this case, there are only two possible outcomes: the flight is delayed, or it is not delayed.
Subtract the probability of the flight being delayed (0.21) from the total probability (1).

1 - 0.21 = 0.79

The perimeter of the triangle is 170 inches.

To solve for the perimeter, we first need to find the length of the perpendicular height. We can do this using the sine function:

sin(35°) = 46/x

x = 46/sin(35°) = 65 inches

Now that we know the length of the perpendicular height, we can find the length of the base of the triangle using the cosine function:

cos(35°) = 65/x

x = 65/cos(35°) = 75 inches

The perimeter of the triangle is the sum of the lengths of the three sides, so the perimeter is:

P = 65 + 75 + 30

= 170 inches

Referring to exhibit 8-2, we can see that the sample size is 400, and the population standard deviation is 10.

Based on these values, we can use the formula for the margin of error:
Margin of error = Z * (σ/√n)
Where Z is the Z-score for the desired level of confidence (in this case, 0.95), σ is the population standard deviation, and n is the sample size. Using a Z-score of 1.96 (which corresponds to a 0.95 confidence level), we can plug in the values:
Margin of error = 1.96 * (10/√400)
Simplifying this equation, we get:
Margin of error = 1.96 * (10/20) = 0.98
Therefore, with a 0.95 probability, the sample mean will provide a margin of error of approximately 0.98.
Based on Exhibit 8-2, with a 0.95 probability, the sample mean will provide a margin of error of "X" (please insert the value provided in the exhibit). This means that we can be 95% confident that the true population mean lies within the sample mean ± X.

There are 5 different quadrilaterals that can be drawn using the given points A, B, C, D, and E.

To determine the number of different quadrilaterals that can be drawn using the given points A, B, C, D, and E, we need to consider the combinations of these points.

A quadrilateral consists of four vertices, and we can select these vertices from the five given points.

The number of ways to choose four vertices out of five is given by the binomial coefficient "5 choose 4," which is denoted as C(5, 4) or 5C4.

The formula for the binomial coefficient is:

C(n, r) = n! / (r!(n-r)!)

Where "n!" denotes the factorial of n.

Applying the formula to our case, we have:

C(5, 4) = 5! / (4!(5-4)!)

= 5! / (4!1!)

= (5 * 4 * 3 * 2 * 1) / ((4 * 3 * 2 * 1) * 1)

= 5

Therefore, there are 5 different quadrilaterals that can be drawn using the given points A, B, C, D, and E.

Dimensions of the box is length = 135 m, width = 81 m, height = 27 m

Step-by-step explanation:

The box contains 15 identical cubes therefore, we have

Edge length of cube = Side, s, of cube

15 × s³ = 295245 m³

s = ∛19683 = 27 m

Hence the edge length of the cube = 27 m

The dimension of the box is length =  5 × 27 = 135 m

True. The solution of a system of linear equations in two variables is the point (x, y) where the two lines intersect. This point satisfies both equations in the system simultaneously.

A system of linear equations in two variables is a set of two equations that can be written in the form:

a₁x + b₁y = c₁
a₂x + b₂y = c₂

where x and y are the variables and a₁, b₁, c₁, a₂, b₂, and c₂ are constants. The goal is to find the values of x and y that satisfy both equations in the system.

Geometrically, each equation in the system represents a line in the two-dimensional plane. The solution of the system is the point (x, y) where the two lines intersect. This point satisfies both equations simultaneously and is the only point that does so.

To find the solution of a system of linear equations, we can use various methods such as substitution, elimination, or matrices. These methods involve manipulating the equations in the system to eliminate one of the variables and solve for the other. Once we have the value of one variable, we can substitute it back into one of the equations to solve for the other variable. The solution of the system is then the ordered pair (x, y) that satisfies both equations.

Given:

The vertices of the rectangle ABCD are A(-3,4), B(-1,4), C(-1,-1) and D(-3,-1).

It is reflected over the line x=2.

To find:

The vertices of the image A'B'C'D'.

Solution:

If a figure is reflected over the line x=a, then

\((x,y)\to (-(x-a)+a,y)\)

\((x,y)\to (-x+a+a,y)\)

\((x,y)\to (-x+2a,y)\)

The rectangle ABCD is reflected over the line x=2. So, the rule of reflection is

\((x,y)\to (-x+2(2),y)\)

\((x,y)\to (-x+4,y)\)

Using this rule, we get

\(A(-3,4)\to A'(-(-3)+4,4)\)

\(A(-3,4)\to A'(3+4,4)\)

\(A(-3,4)\to A'(7,4)\)

Similarly,

\(B(-1,4)\to B'(5,4)\)

\(C(-1,-1)\to C'(5,-1)\)

Subtract 3x from both sides to isolate the -12:

3x - 12 = 11x

3x - 3x - 12 = 11x - 3x

-12 = 8x

8x = -12

Divide both sides by 8:

\(\\\frac{8x}{8} = \frac{-12}{8}\\x = \frac{-12}{8}\\\)

In standard form, this quadratic is

x^2 - 23a - 50 = 0

Factoring this, we get (x - 25)(x + 2) = 0

The probability that event B will occur is 0.45

Step-by-step explanation:

Given;

probability that event A occurs, P(A) = 0.4

the probability that events A and B both occur, P(A ∩ B) = 0.25

the probability that either event A or event B occurs, P(A ∪ B) = 0.6

To determine the probability that event B will occur, we use probability addition rule;

P(A) + P(B) = P(A ∩ B) + P(A ∪ B)

0.4 + P(B) = 0.25 + 0.6

0.4 + P(B) = 0.85

P(B) = 0.85 - 0.4

P(B) = 0.45

Therefore, the probability that event B will occur is 0.45

The simplified expression for (f ∘ g)(x) is 2 + x (option d).

To find and simplify (f ∘ g)(x), we need to substitute the expression for g(x) into f(x) and simplify.

Given:

f(x) = log₃(9x)

g(x) = \(3^x\)

Substituting g(x) into f(x):

(f ∘ g)(x) = f(g(x)) = log₃\((9 * 3^x)\)

Now, we simplify the expression:

log₃\((9 * 3^x)\) = log₃(9) + log₃\((3^x)\)

Since logₓ(a * b) = logₓ(a) + logₓ(b), we have:

log₃(9) + log₃\((3^x)\) = log₃\((3^2)\) + x

Using the property logₓ\((x^a)\) = a * logₓ(x), we get:

log₃\((3^2)\) + x = 2 * log₃(3) + x

Since logₓ\((x^a)\) = a, where x is the base, we have:

2 * log₃(3) + x = 2 + x

Therefore, (f ∘ g)(x) simplifies to:

(f ∘ g)(x) = 2 + x

Answer:

8:4:12

Step-by-step explanation:

The answer is (b) The system has no solution when a = 3.

We can use row reduction to determine the solution(s) of the system of linear equations for any value of a. The augmented matrix is:

\begin{bmatrix}

1 & 0 & 0 & 5 \

0 & 0 & 0 & 1 \

a & 1 & 2 & 6

\end{bmatrix}

First, we can use row operations to put the matrix in row echelon form:

\begin{bmatrix}

1 & 0 & 0 & 5 \

0 & 1 & 2 & 6-a \

0 & 0 & 0 & 1

\end{bmatrix}

Now we can see that the system has a unique solution if and only if the third row corresponds to the equation 0x + 0y + 0z = 1, which is never true, so we can conclude that the system has no solution when a is any number. Therefore, the answer is (b) The system has no solution when a = 3.
