A stockbroker has kept a daily record of the value of a particular stock over the years and finds that prices of the stock form a normal distribution with a mean of $8.52 with a standard deviation of $2.38. The stock price beyond which 0.05 of the distribution falls is _________.
Answer:
$12.43
Step-by-step explanation:
Given :
Mean = $8.52
Standard deviation, = $2.38
Stock price which falls beyond 0.05 of the distribution is at the 95th percentile
The 95th percentile distribution has a Pvalue of 1.645 (standard normal table)
We obtain the value of x, with z = 1.645
Using the Zscore relation :
Zscore = (score - mean) / standard deviation
1.645 = (score - 8.52) / 2.38
Cross multiply :
1.645 * 2.38 = score - 8.52
3.9151 = score - 8.52
Score = 8.52 + 3.9151
Score = $12.4351
Stock price beyond 0.05 is $12.43
Determine whether the planes are parallel, perpendicular, or neither. 8x + 8y + 8z = 1, 8x − 8y + 8z = 1 If neither, find the angle between them.
Answer:
Perpendicular
Step-by-step explanation:
If you use desmos and type in both equations, then set z equal to a number, you will see that they are perpendicular to each other.
Using a calculator, we find an angle of approximately 70.53 degrees.
What is an Angle?
an angle is a geometric figure formed by two rays or line segments that share a common endpoint called a vertex. The rays or line segments that form an angle are called the sides of the angle.
To determine whether the planes are parallel, perpendicular, or neither, we can examine the normal vectors of the planes. The plane normal vector is a vector perpendicular to the surface of the plane.
Let's find the normal vectors of the two planes:
Plane 1: 8x + 8y + 8z = 1
The coefficients x, y, and z in the equation represent the components of the normal vector. So the normal vector of Plane 1 is (8, 8, 8).
Plane 2: 8x - 8y + 8z = 1
Similarly, the normal vector of Plane 2 is (8, -8, 8).
Now we need to compare the two normal vectors to determine their relationship.
If two vectors are parallel, their direction vectors are scalar multiples of each other. In other words, one vector can be obtained by multiplying another vector by a constant.
If two vectors are perpendicular, their dot product is zero.
Let's compare the normal vectors:
Dot product of normal vectors = (8)(8) + (8)(-8) + (8)(8) = 64 - 64 + 64 = 64
Since the dot product is not zero, the normal vectors are not perpendicular.
Since the normal vectors are not scalar multiples of each other, the planes are neither parallel nor perpendicular.
We can use the dot product formula to find the angle between the planes:
cosθ = (dot product of normal vectors) / (magnitude of plane 1 normal vector) * (magnitude of plane 2 normal vector)
cosθ = 64 / (sqrt(8^2 + 8^2 + 8^2)) * (sqrt(8^2 + (-8)^2 + 8^2))
cosθ = 64 / (sqrt(192)) * (sqrt(192))
cosθ = 64 / (sqrt(192) * sqrt(192))
cosθ = 64/192
cosθ = 1/3
θ = arccos(1/3)
Using a calculator, we find an angle of approximately 70.53 degrees.
The planes are therefore neither parallel nor perpendicular, and the angle between them is approximately 70.53 degrees.

Which of the following logarithmic expressions is equivalent to the logarithmic expression shown below?
2 log3 (u) − 6 log3 (p)
Answer:
The 2nd one is the right answer
The logarithmic expression equivalent to the given expression is second option log₃ (u² / p⁶).
What are Logarithms?A logarithm is simply the opposite function of the exponentiation.
It is the exponent to which a number or value is raised to get some other number.
That is, if c = aˣ, then we can write it as x =logₐ c.
The given logarithmic expression is,
2 log₃ (u) - 6 log₃ (p)
In order to simplify this, we have to know the logarithmic rules.
logₐ (bⁿ) = n logₐ b
logₐ (x) - logₐ (y) = logₐ (x/y)
Using these rules,
2 log₃ (u) - 6 log₃ (p) = log₃ (u²) - log₃ (p⁶) [Using the first rule]
= log₃ (u² / p⁶) [Using the second rule]
Hence the equivalent expression is log₃ (u² / p⁶).

The food company is now designing soup cans. They currently make a large can of soup that holds 24oz of soup. They would like to make a single serve can that holds only 8oz of soup. The large can has a surface area of 100.48in². What will the new single serving surface area be? Explain or show your reasoning.
The surface area of the new single-serving soup can, with a volume ratio of 24:8, will be approximately 11.164 square inches.
To determine the surface area of the new single-serving soup can, we can use the concept of ratios and proportions.
Let's assume the radius of the large can is represented by R and the radius of the single-serving can is represented by r.
The volume of a cylinder can be calculated using the formula V = πr^2h, where V is the volume, r is the radius, and h is the height.
We know that the large can has a volume of 24oz, so we have:
24 = πR^2h
Now, we need to find the height of the single-serving can. Since the large can and the single-serving can have the same height (we assume), we can set up a ratio of their volumes:
24/8 = πR^2h / πr^2h
Simplifying the equation, we have:
3 = (R^2h) / (r^2h)
Since the height cancels out, we can rewrite the equation as:
3 = R^2 / r^2
To find the ratio of the surface areas, we square both sides of the equation:
9 = (R^2 / r^2)^2
Now, we can find the surface area ratio:
100.48 / A = 9
Solving for A (the surface area of the single-serving can), we have:
A = 100.48 / 9
Calculating the value, we find that the new single-serving surface area will be approximately 11.164 in².
Therefore, the new single-serving soup can will have a surface area of approximately 11.164 square inches.

If the force remains constant with magnitude f1 while the object moves a distance d , the final speed of the object is v1 . what is the final speed v2 (in terms of v1 ) if the net force is f2=2f1 and the object moves the same distance d while the force is being applied?
The final speed v2 is √6 times the initial speed v1, when the net force is 2f1 and the object moves the same distance d while the force is being applied.
We can use the work-energy theorem to solve this problem, which states that the work done on an object by a net force is equal to the change in its kinetic energy.
When the force has magnitude f1 and the object moves a distance d, the work done is:
W = f1 * d
This work changes the kinetic energy of the object from zero to (1/2) * m * v1^2, where m is the mass of the object. Therefore, we have:
f1 * d = (1/2) * m * v1^2
Solving for v1, we get:
v1 = sqrt((2 * f1 * d) / m)
Now, when the net force has magnitude f2 = 2f1 and the object moves the same distance d, the work done is:
W = f2 * d = 2f1 * d
This work changes the kinetic energy of the object from (1/2) * m * v1^2 to (1/2) * m * v2^2, where v2 is the final speed of the object. Therefore, we have:
2f1 * d = (1/2) * m * (v2^2 - v1^2)
Solving for v2, we get:
v2 = sqrt(v1^2 + (4 * f1 * d) / m)
Substituting the expression for v1, we get:
v2 = sqrt((4 * f1 * d) / m + (2 * f1 * d) / m)
Simplifying, we get:
v2 = sqrt(6) * v1
Therefore, the final speed v2 is sqrt(6) times the initial speed v1.

B.The graph shifts 8 units right and 7 units down.
C.The graph shifts 7 units left and 8 units up.
D.The graph shifts 7 units right and 8 units down.
The correct answer is option (D) "The graph shifts 7 units right and 8 units down".Explanation:To solve the given question, we need to use the rules for vertical and horizontal shifts, which are as follows:
Vertical Shift: y=f(x)+a moves the graph of f(x) upward if a > 0 and downward if a < 0.Horizontal Shift: y=f(x+a) moves the graph of f(x) left if a > 0 and right if a < 0.Now, let's transform the function f(x) into function g(x) and determine the shift required.The transformation of f(x) to g(x) is: g(x) = f(x - a) + bwhere a = horizontal shift and b = vertical shiftThe equation of the given functions is:f(x) = 1/(x − 2) and g(x) = 1/(x^(5/9))Let's set the equation of function f(x) in the standard form:y = 1/(x - 2)and the equation of function g(x) in the standard form:y = 1/(x^(5/9))
Now, we can observe that:To transform the graph of f(x) onto the graph of g(x), we need to shift the graph of f(x) right by 7 units and down by 8 units, which is given in option (D).Hence, the correct option is (D) "The graph shifts 7 units right and 8 units down".
The graph shifts 7 units right and 8 units down is the statement that describes the transformation of the graph of function f onto the graph of function g.Conclusion:Thus, we have determined the correct answer with an explanation and concluded that the correct option is (D) "The graph shifts 7 units right and 8 units down".

What do you mean by transformation?A function, f, that maps to itself is known as a transformation, or f: X X. The original image X is transformed into the final image X. This transformation can use any operation, or a combination of operations, including translation, rotation, reflection, and dilation. Through the use of translation, rotation, reflection, and dilation, a function can be shifted in one direction or another. Rotation around a point is another method for scaling a function.
Mathematical figures in two dimensions move about a coordinate plane in accordance with transformations.

Answer:
y = - 9x + 14
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = (- 4, 50 ) and (x₂, y₂ ) = (5, - 31 )
m = \(\frac{-31-50}{5-(-4)}\) = \(\frac{-81}{5+4}\) = \(\frac{-81}{9}\) = - 9 , then
y = - 9x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (5, - 31 )
- 31 = - 9(5) + c = - 45 + c ( add 45 to both sides )

Statistics help present data precisely and draw meaningful conclusions. While presenting data, one should be aware of using adequate statistical measures.
Readers are generally interested in knowing the variability within the sample, descriptive data should be precisely summarized with SD. The use of SEM should be limited to computing CI which measures the precision of population estimate. Journals can avoid such errors by requiring authors to adhere to their guidelines.
Studying the entire population is time and resource-intensive and not always feasible; therefore studies are often done on the sample, and data are summarized using descriptive statistics. These findings are further generalized to the larger, unobserved population using inferential statistics.
