(2) 44% of the students in Prof. Young's class are Liberal Arts major, 64% major in Business Administration, and 39% major in both. Compute the probability that a student selected at random in Prof. Young's class major in Liberal Arts or Business Administration.
The probability that a student selected at random from the class majors in Liberal Arts or Business Administration is 0.69 or 69%.
Let us say that the event that a student is a Liberal Arts major is 'LA' and the event that a student is a Business Administration major is 'BA'.
Now according to the question, we know that 44% of students are Liberal Arts majors, 64% of students are Business Administration majors,
and 39% of students are majoring in both.
With this information, we can say that:
P(LA) = 44% = 0.44
P(BA) = 64% = 0.64
• P(LAN BA) = 39% = 0.39
Now in order to find the probability that a student
is selected at random majors in either Liberal Arts
or Business Administration, we need to compute the value of P(LA U BA), which is the probability of either of the event happening.
The formula for the probability of the union of two events can be used to find the union that is: PILA U BA) = P(LA)+P(BA)-PILAN BA)
Now by substituting the values in the above equation, we get:
P(LA U BA) = 0.44 + 0.64 -0.39
P(LA U BA) = 0.69

A square a rectangle have the same perimeter of a square has a side length of 8x units. The rectangle has a length of (5x + 12) and a width of 10 units. what will be the perimeter of both a rectangle and the square
Answer:
Step-by-step explanation:
The perimeter of a square is calculated by multiplying the length of one side by 4. Since the side length of the square is 8x units, the perimeter of the square is 4 * 8x = 32x units.
The perimeter of a rectangle is calculated by adding the lengths of all four sides or by using the formula 2 * (length + width). Since the length of the rectangle is (5x + 12) units and the width is 10 units, the perimeter of the rectangle is 2 * ((5x + 12) + 10) = 10x + 44 units.
Since both shapes have the same perimeter, we can set their perimeters equal to each other and solve for x:
32x = 10x + 44 22x = 44 x = 2
Substituting this value of x back into the expression for the perimeter of either shape, we find that the perimeter of both the square and the rectangle is 64 units.

Let G be the center of the equilateral triangle XYZ. A dilation centered at G with scale factor -3/4 is applied to triangle XYZ, to obtain triangle X'Y'Z'. Let A be the area of the region that is contained in both triangles XYZ and X'Y'Z'. Find A/the area of XYZ.
The calculated value of the expression A/the area of XYZ is [tex]\frac{49\sqrt3}{216}[/tex]
Finding the value of A/the area of XYZFrom the question, we have the following parameters that can be used in our computation:
Center of the equilateral triangle XYZ = GDilation centered at G with scale factor = 3/4By the ratio of corresponding sides (see attachment for figure), we have
(x + 2y)/(2x + y) = 3/4
By comparison, we have
x + 2y = 3
2x + y = 4
This gives
(x, y) = (5/3, 2/3)
The triangles are equilateral triangles
So, we have
Area of XYZ = 1/2 * side length² * sin(60)
This gives
Area of XYZ = 1/2 * (2x + y)² * sin(60)
Substitute the known values in the above equation
Area of XYZ = 1/2 * (4)² * sin(60)
Evaluate
Area of XYZ = 4√3
The region A is a trapezoid
So, the area is
A = 1/2 * Sum of parallel sides * height
So, we have
A = 1/2 * (x + y) * (x² - y²)
Recall that (x, y) = (5/3, 2/3)
So, we have
A = 1/2 * (5/3 + 2/3) * ((5/3)² - (2/3)²)
Evaluate
A = 49/18
Finding A/the area of XYZ, we have
A/the area of XYZ = 49/18 ÷ 4√3
This gives
A/the area of XYZ = 49/72 ÷ √3
Rationalize
A/the area of XYZ = [tex]\frac{49\sqrt3}{216}[/tex]

Identify the line of symmetry for the function below:
g(x) = |x +9|- 11
Answer:
x = -9
Step-by-step explanation:
As this is an absolute value function, the line of symmetry is the x-value of the maximum/minimum point. An absolute value function can be denoted as y = |x - h| + k, where (h, k) is the maximum/minimum point. We only need the x-value of the maximum/minimum point, so we only have to look at "h". Now, we can use y = |x - h| + k and turn it into g(x):
y = |x - h| + k
g(x) = |x - -9| + -11 --> this means h = -9, and the line of symmetry is at x = -9
g(x) = |x + 9| - 11
Answer:
I think x equals --9
Earthworm Rivals are building the set for
their new music video. There is a tower made
of 9 glowing bricks that stands 5. 4 meters tall. If each of the bricks is the same exact size,
how tall is each brick?
Since each of the bricks is the same exact size, then each brick is 0.6 meters tall.
To determine the height of each glowing brick, we need to divide the total height of the tower (5.4 meters) by the number of bricks (9). This gives us the average height of each brick.
Using the formula for division, we can write this as:
Height of each brick = Total height of tower / Number of bricks
Plugging in the given values, we get:
Height of each brick = 5.4 meters / 9 bricks
Simplifying this expression, we can cancel out the units of "bricks" to get:
Height of each brick = 0.6 meters
Therefore, each glowing brick in the tower is 0.6 meters tall.

Answer:
it’s A
Step-by-step explanation:
it’s a because the right triangle is always 90°.As you can see there is 42° so you subtract to find the missing number.
How many non-identical triangles can be made using
these side lengths: 4 cm, 8 cm, and 14 cm?
With side lengths of 4, 8, and 14 cm, only one non-identical triangle can be formed.
This is due towards the triangle inequality theorem, which stipulates that the total of any two triangle sides must be bigger than the third side. In this instance, 4 cm plus 8 cm equals 12 cm, that is smaller than 14 cm.
A triangle cannot be formed with these side lengths since they do not meet the triangle inequality theorem. To elaborate, a triangle is created by joining three line segments to create a closed form with three angles.
These line segments' lengths are referred to as the triangle's sides. The total of both sides must be higher than the length of the third one to qualify for a triangle to be present. The triangle inequality hypothesis is what this states.
It is impossible to build a triangle with the side lengths of 4 cm, 8 cm, and 14 cm since the sum of the two shorter sides (4 cm + 8 cm = 12 cm) is less than the length of the longest side (14 cm). Hence, One non-identical triangle can be made.

At 12 PM, the number of students who heard the rumor is 227 and is increasing at a rate of 24 students per hour. Write a differential equation to describe the situation. dP/dt =?
The differential equation to describe the situation is:
dP/dt = 0.000508 * P * (1 - P/732)
We can write a logistic differential equation to describe the rate of change of students who heard the rumor. The equation is:
dP/dt = k * P * (1 - P/M)
where dP/dt is the rate of change in the number of students who heard the rumor, k is a constant, P is the number of students who have heard the rumor at a given time, and M is the maximum capacity of the school (732 students).
At 12 PM, P = 227 and dP/dt = 24 students per hour. We can plug these values into the equation:
24 = k * 227 * (1 - 227/732)
Now, solve for k:
k ≈ 0.000508

Suppose that the demand for a product is given by 2p²q = 10000 + 9000p² (a) Find the elasticity when p = $50 and q = 4502. (b) What type of elasticity is this? (elastic, unitary or inelastic?)
(c) How would the revenue be affected by an increase in price?
(a) The elasticity at p = $50 and q = 4502 is 2.778.
(b) The elasticity is elastic.
(c) An increase in price would result in a decrease in revenue.
How to determined the elasticity of demand?(a) To find the elasticity when p = $50 and q = 4502, we first need to find the partial derivatives of q with respect to p and then use the elasticity formula:
Demand: 2p²q = 10000 + 9000p²
Partial derivative of q with respect to p: 4pq = 18000p
When p = $50 and q = 4502:
4(50)(4502) = 900800
Elasticity:
e = (p/q) * (dq/dp) = (50/4502) * (900800/18000) = 2.778
(b) To determine what type of elasticity this is, we look at the value of the elasticity calculated in part (a). Since the elasticity is greater than 1, we know that this is an elastic demand.
(c) To determine how the revenue would be affected by an increase in price, we need to look at the relationship between elasticity and revenue. If demand is elastic,
Then an increase in price will result in a decrease in total revenue, and if demand is inelastic, then an increase in price will result in an increase in total revenue.
Since we know that the demand is elastic (from part (b)), we can conclude that an increase in price will lead to a decrease in revenue.

Find two vectors in opposite directions that are orthogonal to the vector u. (The answers are not unique. Enter your answer as a comma-separated list of vectors.) u = (5, -4,8) Determine whether the planes are orthogonal, parallel, or neither
The cross-product of u and v:
w = u × v = (5, -4, 8) × (-8, -4, 5) = (-20, -60, 32)
Thus, w is orthogonal to u. Since we need two vectors in opposite directions, we can negate w:
-w = (20, 60, -32)
Therefore, the two orthogonal vectors in opposite directions are w = (-20, -60, 32) and -w = (20, 60, -32).
To find two vectors that are orthogonal to u, we can use the cross-product. Let v = (4,5,0) and w = (-8,0,5). Then v x u = (40,40,45) and w x u = (20,-40,20). So two vectors orthogonal to u are (40,40,45) and (20,-40,20).
To determine whether two planes are orthogonal, parallel, or neither, we can look at the normal vectors of each plane. Let the first plane be defined by the equation 2x + 3y - z = 4 and the second plane being defined by the equation :
4x + 6y - 2z = 8.
The normal vector of the first plane is (2,3,-1) and the normal vector of the second plane is (4,6,-2).
Since the dot product of these two normal vectors is -2(3) + 3(6) - 1(2) = 14, which is not equal to 0, the planes are not orthogonal.
To determine if they are parallel, we can check if the ratio of their normal vectors is constant. Dividing the second normal vector by the first, we get (4/2, 6/3, -2/-1) = (2,2,2). Since this is a constant ratio, the planes are parallel.

1) Last year a computer cost $1,600 to purchase. A year later the same computer cost $1,850 to purchase. By what percent did the cost of the computer increase? (please show your work)
2)A flock of 50 geese landed at a pond. Later that day there were 75 in the pond. By what percent did the number of geese increase?
a
80%
b
50%
c
2%
d
10%
Answer:
1) 15.625% increase. 1850-1600=250. 250/1600=0.15625. 0.15625x100= 15.625.
2) 50%
Step-by-step explanation:
1) 1850-1600=250. 250/1600=0.15625. 0.15625x100= 15.625.
2) 75-50=25. 25/50=0.5. 0.5x100=50
