Rounding to the nearest cm², the area of the shaded region is 32 cm².

The area of a triangle is the measure of the region enclosed by the three sides of a triangle. It is measured in square units. The formula to find the area of a triangle is given as:

Area = 1/2 x base x height

where "base" is the length of the side of the triangle that is perpendicular to the height and "height" is the distance between the base and the opposite vertex.

The base and height can be any two sides of the triangle as long as the height is perpendicular to the base. If the base and height are not known, they can be found using the Pythagorean theorem or other trigonometric functions.

We can find the area of the shaded region by subtracting the area of triangle ABD from the area of rhombus ABCD.

To find the area of triangle ABD, we need to first find the length of BD. Since angle BAD is 70 degrees and ABCD is a rhombus, we know that angle BCD is also 70 degrees. Therefore, angle BXD is 70 degrees / 2 = 35 degrees.

Using trigonometry, we can find BD:

tan(35) = BD/9

BD = 9 tan(35)

BD ≈ 5.458 cm

To find the area of triangle ABD, we use the formula:

Area of triangle = (base x height) / 2

The base of triangle ABD is BD, which we just found, and the height is the perpendicular distance from A to BD. We can find this distance using trigonometry and the fact that angle BAC is 20 degrees:

tan(20) = height/9

height = 9 tan(20)

height ≈ 3.170 cm

Therefore, the area of triangle ABD is:

Area of triangle ABD = (BD x height) / 2

Area of triangle ABD = (5.458 x 3.170) / 2

Area of triangle ABD ≈ 8.661 cm²

The area of rhombus ABCD is:

Area of rhombus ABCD = (diagonal 1 x diagonal 2) / 2

Area of rhombus ABCD = (9 x 9) / 2

Area of rhombus ABCD = 40.5 cm²

Therefore, the area of the shaded region is:

Area of shaded region = Area of rhombus ABCD - Area of triangle ABD

Area of shaded region = 40.5 - 8.661

Area of shaded region ≈ 31.839 cm²

Rounding to the nearest cm², the area of the shaded region is 32 cm².

Step-by-step explanation:

The possible widths for the rectangular mural are between 10 and 15 feet. We can also list the number of possible widths within this range, which is six. They are 10 feet, 11 feet, 12 feet, 13 feet, 14 feet, and 15 feet.

To determine the possible widths for the rectangular mural with an area of 60 square feet, we can use the formula for the area of a rectangle, which is length multiplied by width. Since the area is given as 60 square feet and the length should be between 4 and 6 feet, we can set up inequality as follows:

4w ≤ 60 ≤ 6w

where w is the width of the mural in feet. Solving this inequality for w, we get:

10 ≤ w ≤ 15

It is important to consider the dimensions carefully to ensure that the mural meets the requirements and fits in the desired space. By having multiple possible widths, the class can select the most suitable one based on the available resources and space.

Answer: Maricopa Success invested $13,350 in CDs, $38,350 in bonds, and $23,300 in stocks.

Step-by-step explanation:

Let x be the amount invested in CDs.

Then, the amount invested in bonds would be (x + $25,000) and the amount invested in stocks would be ($75,000 - x - (x + $25,000)) = ($50,000 - 2x).

The annual income from the investments is $4,142.5, so we can set up the following equation:

0.0375x + 0.038(x + $25,000) + 0.103($50,000 - 2x) = $4,142.5

Simplifying the equation, we get:

0.0755x + $5,150 = $4,142.5

0.0755x = -$1,007.5

x = -$1,007.5 / 0.0755

x = $13,350

Therefore, the amount invested in CDs is $13,350.

The amount invested in bonds is $13,350 + $25,000 = $38,350.

The amount invested in stocks is $75,000 - $13,350 - $38,350 = $23,300.

So, Maricopa Success invested $13,350 in CDs, $38,350 in bonds, and $23,300 in stocks.

a. The probability of an empty set is always zero. Therefore, P(∅) = 0.

b. The probability of the union of two events, A and B, is given by the formula P(A∪B) = P(A) + P(B) - P(A∩B). Substituting the values given in the question, we get:

P(A∪B) = P(A) + P(B) - P(A∩B)

= 0.3 + 0.2 - 0.1

Therefore, P(A∪B) = 0.4.

c. The probability of the intersection of A and B is given by the formula P(A∩B). Substituting the values given in the question, we get:

P(A∩B) = 0.1

Therefore, P(A∩B) = 0.1.

d. The probability of the intersection of A and the complement of B is given by the formula P(A∩B'). The complement of B is the set of all outcomes that are not in B. Since the sample space is not defined in the question, we cannot calculate P(B'). Therefore, we cannot calculate P(A∩B').

e. The probability of the union of A and B is given by the formula P(A∪B). Substituting the values given in the question, we get:

P(A∪B) = P(A) + P(B) - P(A∩B)

Therefore, P(A∪B) = 0.4.

In probability theory, the union of two events A and B is the set of outcomes that belong to either A or B or both. The intersection of two events A and B is the set of outcomes that belong to both A and B. The complement of an event A is the set of outcomes that do not belong to A.

(a) The null hypothesis is that the true average compressive strength of the mixture is less than or equal to 1300 KN/m2.

The alternative hypothesis is that the true average compressive strength of the mixture is greater than 1300 KN/m2.

(b) To find the P-value, we need to calculate the probability of getting a sample mean of 1340 or greater, assuming the null hypothesis is true. Using the sample size n=12 and sample standard deviation σ=67, the test statistic is (1340-1300)/(67/sqrt(12)) = 2.523.

The P-value is the probability of getting a value of 2.523 or greater from a t-distribution with 11 degrees of freedom, which is 0.0193.

(c) The test statistic when μ = 1350 follows a t-distribution with 11 degrees of freedom.

The mean of the test statistic is equal to the true value of the mean, which is 1350. The standard deviation of the test statistic can be calculated as σ/sqrt(n) = 67/sqrt(12) = 19.341.

To find the probability of a type II error with α = 0.01, we need to calculate the probability of accepting the null hypothesis when the true value of the mean is 1350.

This can be calculated using the t-distribution with 11 degrees of freedom and the critical value corresponding to α=0.01, which is 2.718. The probability of a type II error is the probability that the test statistic is less than 2.718 when the true value of the mean is 1350, which is 0.2157 (rounded to four decimal places).

One characteristic of all exponential functions is that they change by a constant factor at each step, which means that they exhibit exponential growth or decay.

The constant factor by which an exponential function changes is called the base, which is usually denoted by the symbol "b". If b is greater than 1, the function exhibits exponential growth, and if b is between 0 and 1, the function exhibits exponential decay.

For example, the function f(x) = 2^x is an exponential function with a base of 2. At each step, the function increases by a factor of 2. For instance, f(0) = 1, f(1) = 2, f(2) = 4, f(3) = 8, and so on.

On the other hand, the function g(x) = (1/2)^x is an exponential function with a base of 1/2. At each step, the function decreases by a factor of 1/2. For instance, g(0) = 1, g(1) = 1/2, g(2) = 1/4, g(3) = 1/8, and so on.

Therefore, exponential functions exhibit a characteristic change by a constant factor at each step, which leads to either exponential growth or decay.

The mean of time between success is 0.2 minutes, rate parameter is 5 and probability that the time to succeed will be more than 55 minutes is approximately 0.000026 when Poisson random variable has a mean of 5 successes over a 125-minute period.

They can be found out by:

(A) The mean of the random variable defined by the time between successes can be found by using the fact that the Poisson distribution is memory less, which means that the time between successes follows an exponential distribution. The mean of an exponential distribution is equal to the reciprocal of the rate parameter, so:

 Mean of time between successes = 1 / rate parameter = 1 / 5 = 0.2 minutes

(B) The rate parameter of the exponential distribution can be found using the fact that the mean of the exponential distribution is equal to the reciprocal of the rate parameter, as derived in part a:

 rate parameter = 1 / mean of time between successes = 1 / 0.2 = 5

(C)The probability that the time to success will be more than 55 minutes can be found using the cumulative distribution function (CDF) of the exponential distribution with the rate parameter found in part b:

P(X > 55) = 1 - P(X <= 55) = 1 - F(55) = 1 - (1 - e^{(-5*55)}) = 0.000026 (rounded to 4 decimal places)

Therefore, the probability that the time to success will be more than 55 minutes is very small, approximately 0.000026.
