Answer:
∠ D ≈ 69.0°
Step-by-step explanation:
using the cosine ratio in the right triangle
cos D = \(\frac{adjacent}{hypotenuse}\) = \(\frac{FD}{DE}\) = \(\frac{33}{92}\) , then
∠ D = \(cos^{-1}\) ( \(\frac{33}{92}\) ) ≈ 69.0° ( to the nearest tenth )
How many 1 in x 1 in squares would you need to cover the entire shape above? Explain your reasoning. (Assume that you cut the squares as needed when you get to any corners that are not right angles.
Answers
Answer:
1008 squares
Step-by-step explanation:
You want to know the number of 1-inch squares that would be required to cover the given irregular area.
Figure areaThe given figure can be decomposed into a rectangle that is 4 feet long and 2 feet wide, with two triangular cut-outs. The base of each of those triangles is ...
4 ft - (2 ft +1 ft) = 1 ft
and the height is marked as 1 ft
Triangle area
The area of a triangle is given by ...
A = 1/2bh
Each triangle has an area of ...
A = 1/2(1 ft)(1 ft) = 1/2 ft²
There are 2 of them, so their total area is ...
2 × (1/2 ft²) = 1 ft²
Rectangle area
The area of the overall rectangle is ...
A = LW
A = (4 ft)(2 ft) = 8 ft²
Shaded area
The shaded area of the figure is the difference between the rectangle area and the total area of the two triangle cut-outs:
area = 8 ft² - 1 ft² = 7 ft²
Square inchesA foot is 12 inches, so a square foot is ...
A = (12 in)(12 in) = 144 in²
The figure covers 7 square feet, so its total area in square inches is ...
(7 ft²)×(144 in²/ft²) = 1008 in²
You would need 1008 1-inch squares to cover the entire shape.
The amount of 1 in. by 1 in squares that would be needed to cover the entire area of the shape is: 1008.
How to Find the Area of a Rectangle and a Triangle?The area of the shape = area of the entire rectangle - area of the 2 cut-out triangles.
Area of the entire rectangle = (length)(width)
Length of the entire rectangle = 4 ft
Width of the entire rectangle = 2 ft
Area of the entire rectangle = (4)(2) = 8 ft².
Area of the 2 cut-out triangles = 2(1/2bh) = bh
b = 1 ft
h = 1 ft
Area of the 2 cut-out triangles = (1)(1) = 1 ft².
The area of the shape = 8 - 1 = 7 ft²
Convert 7 ft² to inches squares
1 ft² = 144 in.²
7 ft = 7 × 144
= 1008 in.²
Therefore, the amount of 1 in. by 1 in squares that would be needed to cover the entire area of the shape is: 1008.

Suppose that y varies directly as the square root of x, and that y = 49 when x = 49. What is y when x = 128? Round your answer to two decimal places if necessary
Answers
Since y varies directly with square root x, so
\(y=k\sqrt{x}\)k is the constant of variation
We will find it using the initial values of x and y
Since the initial values are:
y = 49
x = 49
Substitute them in the rule to find k
\(\begin{gathered} 49=k\sqrt{49} \\ 49=k(7) \\ 49=7k \\ \frac{49}{7}=\frac{7k}{7} \\ 7=k \end{gathered}\)The value of k is 7, so the equation will be
\(y=7\sqrt{x}\)We need to find the value of y at x = 128, so
Substitute x in the rule by 128
\(\begin{gathered} y=7\sqrt{128} \\ y=56\sqrt{2}=79.1959595 \end{gathered}\)Round it to two decimal places, so
y = 79.20

Though 70% of women with children younger than 18 years participate in the labor force, society still upholds the stay-at-home mother as the traditional model. Some believe that employment distracts mothers from their parenting role, affecting the well-being of children. In the GSS 2014, respondents were asked to indicate their level of agreement to the statement: "A working mother hurts children". Of the 435 male respondents who answered the question, 18% strongly agreed that a working mother does not hurt children. a, What is the 90% confidence interval for this statistic for males? b. Of the 566 respondents who answered the question, 40% strongly agree that a working mother does not hurt children. What is the 90% confidence level for this statistic?
Answers
a) The 90% confidence interval for this statistic for males is of: (0.1497, 0.2103).
b) The 90% confidence level for this statistic is of: (0.3661, 0.4339).
What is a confidence interval of proportions?A confidence interval of proportions has the bounds given by the rule presented as follows:
\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)
In which the variables used to calculated these bounds are listed as follows:
\(\pi\) is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.The confidence level is of 90%, hence the critical value z is the value of Z that has a p-value of \(\frac{1+0.9}{2} = 0.95\), so the critical value is z = 1.645.
For males, the parameters are given as follows:
\(\pi = 0.18, n = 435\)
Hence the lower bound of the interval is given as follows:
\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.18 - 1.645\sqrt{\frac{0.18(0.82)}{435}} = 0.1497\)
The upper bound of the interval is of:
\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.18 + 1.645\sqrt{\frac{0.18(0.82)}{435}} = 0.2103\)
For the statistic, the parameters are given as follows:
\(\pi = 0.4, n = 566\)
Hence the lower bound of the interval is given as follows:
\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4 - 1.645\sqrt{\frac{0.4(0.6)}{566}} = 0.3661\)
The upper bound of the interval is of:
\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4 + 1.645\sqrt{\frac{0.4(0.6)}{566}} = 0.4339\)

17. Find the circumference given
KL 4.6 in. Round to the nearest
tenth.
Answers
The circumference of the given circle is approximately 47.3 inches.
Since the length of the arc KL and the measure of the central angle ∠KOL are known, we can use the formula for arc length to find the circumference of the circle:
arc length = (central angle / 360°) x circumference
Plugging in the known values, we have:
4.6 in = (35° / 360°) x circumference
Solving for the circumference, we get:
circumference = 4.6 in / (35° / 360°)
circumference = 4.6 in x (360° / 35°)
circumference ≈ 47.3 in (rounded to the nearest tenth)
Therefore, the circumference of the circle is approximately 47.3 inches.

Which of the following statements with respect to political risk is true?
Oa. Political risk premiums are added to the required rate of return to adjust for political risks.
b. Companies cannot take any steps to reduce the potential from loss from expropriation since a foreign
government is involved.
Oc. The risk of expropriation of U.S. assets abroad is high even in traditionally friendly and stable countries.
Od. A company can reduce political risk by structuring operations so that the subsidiary has value only as a part of the
integrated corporate system.
Answers
This statement is true. Political risk is the risk of loss in an investment due to political instability or changes in government policy. Companies can adjust for the potential impact of political risk by adding a political risk premium to their required rate of return. This premium compensates investors for the additional risk associated with the investment due to political factors. The size of the premium will depend on the specific country, the nature of the investment, and the perceived level of political risk. Companies can also take steps to reduce political risk, such as diversifying their operations, investing in political risk insurance, or structuring operations to minimize the value of a subsidiary that might be subject to expropriation.

Using thie model ,The answer is D. 27.
To calculate 9÷1/3 using the model below, we can imagine dividing the green rectangle into thirds vertically. Each third would contain 3 cells.
Then, we can see that there are a total of 9 cells in the rectangle. Since we are dividing by 1/3, we need to find out how many sets of 1/3 are in 9.
We can see that there are 3 sets of 1/3 in each row (since each row contains 3 cells, which are thirds). So, in total, there are 3 rows of 3 sets of 1/3, which gives us:
9÷1/3 = 3 rows x 3 sets of 1/3 = 9 sets of 1/3 = 27
