The magnitude and direction of the resultant vector are 76.158 and 100.496° (rounded to the nearest degree).
So the answer is 76.158; 100°.
To find the magnitude and direction of the resultant vector, we can use the vector addition formula:
R = sqrt(A^2 + B^2 + 2ABcosθ)
Where R is the magnitude of the resultant vector, A and B are the magnitudes of the two vectors, and θ is the angle between them.
First, we can convert the given angles to radians by multiplying by π/180:
40° * π/180 = 0.698 radians
130° * π/180 = 2.268 radians
Then we can plug in the given values and solve for the magnitude of the resultant vector:
R = sqrt(30^2 + 70^2 + 2(30)(70)cos(2.268 - 0.698))
R = 76.158 (rounded to the thousandths place)
Next, we can use the law of cosines to find the angle between the resultant vector and the 30-magnitude vector:
cosθ = (R^2 + A^2 - B^2) / 2RA
cosθ = (76.158^2 + 30^2 - 70^2) / (2 * 76.158 * 30)
cosθ = 0.499
θ = cos^-1(0.499)
θ = 60.496°
Since this angle is between the 30-magnitude vector and the x-axis, we need to add 40° to get the angle between the resultant vector and the x-axis:
60.496° + 40° = 100.496°

Unit 5 Systems of equations and inequalities, Homework 10 systems by inequalities
To solve a system of equations, you need to find the values of the variables that satisfy both equations simultaneously. There are different methods to solve systems of equations, including substitution, elimination, and graphing. Here's an example of using substitution:
Solve the system of equations:
2x + y = 5
x - y = 1
From the second equation, we get x = y + 1. Substitute this expression for x into the first equation:
2(y + 1) + y = 5
Simplifying and solving for y, we get:
3y + 2 = 5
3y = 3
y = 1
Then, substitute y = 1 into x = y + 1 to get:
x = 2
So the solution to the system of equations is x = 2 and y = 1.
To solve a system of inequalities, you need to find the values of the variables that satisfy both inequalities simultaneously. There are different methods to solve systems of inequalities, including graphing and substitution. Here's an example of using graphing:
Solve the system of inequalities:
x + y ≤ 3
x - y > 1
First, graph the boundary lines of each inequality. For the first inequality, the boundary line is x + y = 3, which is a line with intercepts (3, 0) and (0, 3). To decide which side of the line to shade, test a point that is not on the line, such as (0, 0):
0 + 0 ≤ 3, which is true
Therefore, shade the side of the line that contains the origin.
For the second inequality, the boundary line is x - y = 1, which is a line with intercepts (1, 0) and (0, -1). To decide which side of the line to shade, test a point that is not on the line, such as (0, 0):
0 - 0 > 1, which is false
Therefore, shade the side of the line that does not contain the origin.
The shaded region that satisfies both inequalities is the region that is below the line x + y = 3 and to the right of the line x - y = 1. This region is a triangle with vertices (1, 2), (2, 1), and (2, 2).

suppose gre verbal scores are normally distributed with a mean of 455 and a standard deviation of 124 . a university plans to offer tutoring jobs to students whose scores are in the top 8% . what is the minimum score required for the job offer? round your answer to the nearest whole number, if necessary.
The minimum score required for the job offer found using normal distribution is 629
To find the minimum score required for the job offer, we have to use the standard normal distribution formula.
Where Z-score can be calculated as,
Z = (x - μ) / σ
Z-score is the number of standard deviations from the mean.
μ = Mean = 455
σ = Standard Deviation = 124
Substituting the values, we get, Z = (x - μ) / σ= (x - 455) / 124
Probability value = 1 - 0.08 = 0.92
The probability of getting scores in the top 8% is 0.92.
By using the standard normal distribution table, we can find the corresponding z-value, where the area under the curve to the right of that value is 0.92.
So, the corresponding Z-value is 1.44.
Z-value = 1.4 = (x - 455) / 124
We can solve the above equation for x (minimum score required for the job offer).
x = Z * σ + μ = 1.4 * 124 + 455 = 628.6 ≈ 629
Round off the answer to the nearest whole number, we get the minimum score required for the job offer is 629.

a real estate agent has 12 properties that she shows. she feels that there is a 40% chance of selling any one property during a week. the chance of selling any one property is independent of selling another property. compute the probability of selling more than 5 properties in one week. round your answer to four decimal places.
The probability of selling more than 5 properties in a week is 0.7494 (rounded to four decimal places).
The probability of selling more than five properties in a week would be calculated using the binomial distribution method. Binomial distribution is used to calculate the probability of an event happening, given a specific number of trials and assuming that each trial is independent of the others. In this case, we want to know the probability of selling more than five properties in a week.
The formula for the probability of selling more than five properties in a week is:
P(X > 5) = 1 - P(X ≤ 5)
Where P is the probability of selling any one property in a week, and X is the number of properties sold in a week.
Using the binomial probability formula, we can determine the probability of selling exactly k properties in one week:
P(X = k) = (n choose k) * p^k * (1-p)^(n-k)
where
n = 12 (total number of properties)
k = number of properties sold
p = 0.40 (probability of selling any one property in a week)
We can now calculate the probability of selling more than 5 properties in a week:
P(X > 5) = 1 - P(X ≤ 5)
P(X > 5) = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5))
P(X > 5) = 1 - [(12 choose 0) * (0.40)^0 * (0.60)^(12-0) + (12 choose 1) * (0.40)^1 * (0.60)^(12-1) + (12 choose 2) * (0.40)^2 * (0.60)^(12-2) + (12 choose 3) * (0.40)^3 * (0.60)^(12-3) + (12 choose 4) * (0.40)^4 * (0.60)^(12-4) + (12 choose 5) * (0.40)^5 * (0.60)^(12-5)]
P(X > 5) = 1 - [0.000015 + 0.0003 + 0.003 + 0.018 + 0.068 + 0.161]
P(X > 5) = 1 - 0.250583

The minute hand of this clock is shown in two positions. The minute hand first forms a 46° angle with the hour hand. It then forms an 84° angle with the hour hand.
How many degrees did the minute hand turn from its first position to its second position?
Enter your answer in the box.
°
The face of a clock. The hour hand points to the 9. The minute hand is rotated to two positions. In its first position, the minute hand is between 10 and 11 so that it forms a 46 degree angle with the hour hand. In its second position, the minute hand is between 11 and 12 so that it forms an 84 degree angle with the hour hand. The angle formed by the first and second position of the minute hand is labeled with a question mark.
To find the number of degrees the minute hand turned from its first position to its second position, we need to find the difference between the two angles formed by the minute and hour hands.
In the first position, the minute hand forms a 46° angle with the hour hand. Since the hour hand is pointing at 10 and the minute hand is between 10 and 11, we know that the hour hand has moved 1/6th of the way from 10 to 11, or 30°. Therefore, the angle between the hour hand and the 12:00 position is 120° + 30° = 150°. So the minute hand is 46° away from 150°, or 104°.
In the second position, the minute hand forms an 84° angle with the hour hand. Since the hour hand is pointing at 10 and the minute hand is between 11 and 12, we know that the hour hand has moved 1/2 of the way from 10 to 11, or 150°. So the minute hand is 84° away from 150°, or 234°.
To find the number of degrees the minute hand turned, we subtract the two angles: 234° - 104° = 130°.
Therefore, the minute hand turned 130° from its first position to its second position.

The value of x, the missing side which is the hypotenuse, is approximately 24.85 units.
What is the missing side of the triangle?To solve this problem, we can use the trigonometric function of sine, since we know the opposite side and we want to find the hypotenuse.
The sine of an angle is defined as the ratio of the length of the opposite side to the length of the hypotenuse:
sin(θ) = opposite/hypotenuse
In this case, θ is the angle 75 degrees, the opposite side is 24, and we want to find the hypotenuse x:
sin(75°) = 24/x
To solve for x, we can cross-multiply:
x * sin(75°) = 24
Then, we can divide both sides by sin(75°):
x = 24 / sin(75°)
Using a calculator, we get:
x = 24.85 units

The correct option is:
Steering wheel the proper distance from the body, at least a foot from the body, right foot should reach behind the brake pedal and knee should be slightly bent.
What is distance?
Distance is a numerical measurement of the amount of space between two objects or points.
First, the distance between the steering wheel and the driver's body should be at least one foot. This ensures that the driver has enough room to operate the pedals and steering wheel without feeling cramped or uncomfortable. Mathematically, we could express this as:
distance between steering wheel and body ≥ 1 foot
Second, the right foot should be able to reach behind the brake pedal, and the knee should be slightly bent. This allows the driver to apply pressure to the brake pedal without having to overextend their leg or foot. Mathematically, we could express this as:length of driver's leg + distance from seat to brake pedal = distance from seat to brake pedal when leg is slightly bent
These considerations help to ensure that the driver is seated in a safe and comfortable position while operating the vehicle.

An inequality in mathematics is a relationship between two values that are not equal. Equality and inequality are not the same thing. The not equal sign is often used to indicate that two values are not equal (). To contrast values, various disparities—no matter how small or large—are used. By changing the two sides until just the variables are left, many fundamental inequalities can be resolved. Yet, a variety of causes fuel inequality: On both sides, negative values are divided or added. Trade right and left.

Based on the measures of center, we can conclude that Wide Awake typically sells more coffee per hour compared to Perks A Lot.
What is Statistics?Statistics is the branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data.
To determine which coffee shop typically sells the most amount of coffee per hour, we need to compare the measures of center for both sets of data. The two common measures of center are the mean and the median.
Calculating the mean and median for both sets of data, we get:
Perks A Lot:
Mean = (10+3.5+3+5+2.5+7+8+5.5+9.5+6+9+4.5)/12 = 5.75
Median = the average of the 6th and 7th numbers when the data is arranged in order: 3, 3.5, 5, 5.5, 6, 7, 8, 9, 9.5, 10
Wide Awake:
Mean = (2.5+10+4+18+4+3+6.5+15+6+5+2.5)/11 = 6
Median = the average of the 5th and 6th numbers when the data is arranged in order: 3, 4, 5, 6, 6.5, 10, 15, 18
Comparing the measures of center, we can see that Perks A Lot has a lower mean and a higher median compared to Wide Awake. This suggests that Perks A Lot sells less coffee on average, but has more consistent sales with less extreme values. On the other hand, Wide Awake has higher average sales, but with a wider range of values.
Therefore, based on the measures of center, we can conclude that Wide Awake typically sells more coffee per hour compared to Perks A Lot.

Asaad having median salary makes more money in comparison to Amahle who makes minimum salary.
From the attached box plot we have,
Box plot always shows,
First Minimum → Lower quartile → Median → Upper quartile → Maximum
The minimum salary for an actuary is equals to
Approximately 35 dollars
And the median salary for a CPA from the box plot is equals to,
Approximately 60 dollars
Here , by comparing the both the values we have,
Median salary for CPA (60 dollars ) is greater than minimum salary for actuary ( 35 dollars ).
The median salary for a CPA is typically higher than the minimum salary for an actuary.
Therefore, Asaad representing median salary makes more money than Amahle .

A right-angled triangle is formed by the diameters of three semicircular regions, A, B and C as shown in the diagram.
It is true that the areas of regions B and C added together equal the area of region A.
What is region?A region is an area of land that has a distinct physical or cultural identity. Regions are typically characterized by particular geographic features, such as mountains, rivers, or seas; by cultural attributes, such as language, religion, or government; or by economic activities, such as farming, mining, or industry.
Assume that A, B, and C will have diameters of a, b, and c, respectively.
Consequently, the semicircle's surface area is,
A = 1/2π(d/2)²
A = (π/8) d²
In a right-angled triangle, the square on the hypotenuse is equal to the particular sum of the squares of one two sides. With a right triangle,
a² = b² +c² ----(1)
The areas for regions A, B, and C will be (π/8) a², (π/8) b², and (π/8) c² accordingly.
Equation 1's (/8) multiplication yields,
(π/8) a² = (π/8) b² +(π/8) c²
The result is
Region A's area is equal to Region B's plus Region C's.

Complete Question:
It is true that the areas of regions B and C formed by the semi circles added together equal the area of region A.
What is semi circle?
In geometry, a semicircle can be defined as a half circle made by cutting the circle into two halves. It is formed when a line passes through the center of a circle and touches the two ends of the circle which is the diameter of the circle.
Let us assume that A, B, and C will have diameters of a, b, and c, respectively.
By the formula of semicircle's surface area,
A = 1/2π(d/2)² where d is the diameter of the semi circle.
A = (π/8) a² [ since diameter of semicircle A is a]
By Pythagoras theorem, In a right-angled triangle, the square on the hypotenuse is equal to the sum of the squares of two sides.
So here from the right angled triangle we get,
a² =b² +c² ----(1)
The area for region A is (π/8) a²
The area of region B is (π/8) b²
and the area of region C is (π/8) c²
Now, Area of region B + Area of region C
= (π/8) b² + (π/8) c²
= (π/8) ( b² +c² )
= (π/8) a² [ from equation (1)]
Hence , Region A's area is equal to Region B's plus Region C's area.
