Using a Z-table, the probability of having a z-score less than 9.33 is virtually 1.000, or 100%.

The stand time for commercial jets is a random variable with a mean of 2 minutes and a standard deviation of 3 minutes. Assuming the distribution of times is approximately normal, we can calculate the probability of certain events.

(a) To find the probability that the wait time is less than 30 minutes, we can standardize the value and use a standard normal distribution table (also known as a Z-table).

First, calculate the z-score:
z = (X - μ) / σ
z = (30 - 2) / 3
z = 28 / 3
z ≈ 9.33

This means it is almost certain that the wait time will be less than 30 minutes.

A plane intersects a cylinder perpendicular to its bases this cross section can be described as a rectangle. Therefore, the correct answer is option 1).

The cross section of a plane intersecting a cylinder perpendicular to its bases is a rectangle. This is because when a plane intersects a cylinder perpendicularly (at right angles) the cross-section area has the shape of a rectangle. The base of the rectangle is determined by the diameter of the cylinder and the height is determined by the length of the cylinder.

A parabola, triangle, and circle are not possible when the plane intersects the cylinder perpendicularly since their shapes cannot accurately represent the intersection of two geometric shapes.

To find the magnitude of r prime of quantity pi over 3 end quantity, we first need to take the derivative of r of t. r prime of t = a vector with two components, sec^2(t) and 2csc(2t) .Then, we can evaluate r prime of pi/3 using these components: r prime of pi/3 = a vector with two components, sec^2(pi/3) and 2csc(2(pi/3)).
Using the fact that sec^2(pi/3) = 4 and csc(2(pi/3)) = -2sqrt(3)/3, we can simplify the vector to: r prime of pi/3 = a vector with two components, 4 and -4sqrt(3)/3
Now, we can find the magnitude of this vector using the formula:

magnitude of a vector = square root of (sum of squares of its components)

magnitude of r prime of pi/3 = square root of (4^2 + (-4sqrt(3)/3)^2)

= square root of (16 + 16/3)

= square root of (64/3)

= 4/square root of 3

Multiplying this by the given constants (1/3 square root of thirty four, 1/2 square root of nineteen, 2 square root of thirteen over three, 4/3 square root of ten), we get the final answer:

magnitude of r prime of quantity pi over 3 end quantity = (4/square root of 3) * (1/3 square root of thirty four) * (1/2 square root of nineteen) * (2 square root of thirteen over three) * (4/3 square root of ten)

= 16/square root of (3 * 34 * 19 * 13 * 10/9)

= 16/square root of 2,583.49

= 16/50.83

= 0.3147 (rounded to four decimal point)

To find the magnitude of r'(π/3), we need to take the square root of the sum of the squared components:

Magnitude of r'(π/3) = √[sec^4(π/3) + (2*cot(2(π/3))*csc^2(2(π/3)))^2]

Once you evaluate the trigonometric functions at π/3 and simplify the expression, you will have the magnitude of r'(π/3).

A confounding variable is a variable that is related to both the independent variable (hours of revision) and the dependent variable (performance in a college-level Spanish language exam).

In this study, potential confounding variables could include the students' prior knowledge of Spanish, their natural ability in language learning, their level of motivation, their access to study resources, and their level of stress or anxiety. These factors could impact both the amount of time a student spends revising and their performance on the exam, making it difficult to determine if the hours of revision directly caused any changes in exam performance. To control for these confounding variables, researchers may consider randomly assigning students to different revision time groups, measuring these other factors, or using statistical analysis techniques to adjust for these variables.
In your study on the effect of revision hours on college-level Spanish language exam performance among 100 college students, potential confounding variables could include:

1. Prior knowledge of Spanish: Students with previous experience in learning Spanish may perform better than those without, regardless of revision hours.
2. Study habits: The quality of study methods can influence the effectiveness of revision hours.
3. Language aptitude: Some students may naturally possess a higher aptitude for language learning, affecting their exam performance.
4. Instructor quality: The effectiveness of the Spanish language instructor can influence student performance.
5. Sleep and stress levels: Adequate sleep and low stress levels can improve a student's ability to retain information during revision.

The correct surface area of the cylinder is  878.06 sq. cm.

From the net of the cylinder we have the diameter of the circular bases of the cylinder.

So, the radius of the circle would be,

r = 13/2

Using the formula for area of circle the surface area of two circular bases would be,

A₁ = 2 × π × r²

A₁ = 2 × π × (13/2)²

A₁ = π × 169/2

A₁ = 265.46 sq. cm.

The length of the rectangle would be equal to the circumference of the circle.

So, the length of the rectangle would be,

l = 2× π × r

l = 2× π × (13/2)

l = 13 × π

l = 40.84 cm

Using the formula for the area of rectangle,

A₂ = l × w

A₂ = 40.84 × 15

A₂ = 612.6 sq. cm.

So, the total surface area of the cylinder would be,

A = A₁ + A₂

A = 265.46 +  612.6

A = 878.06 sq. cm.

This means that the surface area claimed by Talia is incorrect.

To solve this problem, we need to first find the average number of shoppers in the new store at any time.

We know that during business hours, 90 shoppers per hour enter the store and each stays an average of 12 minutes.

To find the average number of shoppers at any time, we need to convert the time each shopper spends in the store to hours:

12 minutes = 0.2 hours

So, on average, each shopper takes up 0.2 hours in the store.

Therefore, the average number of shoppers in the new store at any time is:

90 shoppers/hour x 0.2 hours/shopper = 18 shoppers

Now we can find the percent less that the average number of shoppers in the new store is compared to the original store:

Percent less = (Original - New) / Original x 100%

Percent less = (45 - 18) / 45 x 100%

Percent less = 27 / 45 x 100%

Percent less = 60%

So the answer is A. 60.
To find the average number of shoppers in the new store at any time, we can use the formula:

Average number of shoppers at any time = (Number of shoppers per hour * Average time spent in store) / 60

For the new store:
Average number of shoppers at any time = (90 shoppers per hour * 12 minutes) / 60
Average number of shoppers at any time = 1080 / 60 = 18 shoppers

Now we will find the percentage difference between the average number of shoppers in the original store (45 shoppers) and the new store (18 shoppers):

Percentage difference = ((Original store shoppers - New store shoppers) / Original store shoppers) * 100
Percentage difference = ((45 - 18) / 45) * 100
Percentage difference = (27 / 45) * 100 = 60%

So the average number of shoppers in the new store at any time is 60% less than the average number of shoppers in the original store at any time. Your answer: A. 60

The complete question is attached in figure.

The remaining volume of the cone will be 4247 cubic units.

Let's assume that the base of the square pyramid has side lengths, and let's also assume that the height of the pyramid is h. Then, the volume of the pyramid is:

V(Pyramid)= (1/3) x s² x h

Now, let's consider the inscribed cone. Since the cone is inscribed in the pyramid, the base of the cone must lie at the base of the pyramid, and the vertex of the cone must lie at the apex of the pyramid.

Let's assume that the radius of the base of the cone is r, and let's also assume that the height of the cone is also h. Then, the volume of the cone is:

V( cone)= (1/3) x π x r² x h

Since the cone is inscribed in the pyramid, the base of the cone has the same side length as the base of the pyramid. Therefore, the diameter of the base of the cone is equal to the side length of the square pyramid. Since the radius of the cone is half of the diameter, we can write:

r = (1/2) x s

Substituting this into the formula for the volume of the cone, we get:

V(cone) = (1/3) x π x (1/4) x s² x h

= (1/12) x π x s² x h

Now, we can find the volume of the remaining solid by subtracting the volume of the cone from the volume of the pyramid:

V(remaining) = V(pyramid) - V(cone)

= (1/3) x s² * h - (1/12) x π x s² x h

= (1/3) x s² x h x (1 - (1/4) x π)

So, the volume remaining is approximate:

V(remaining) ≈ 0.79 x s² x h

V(remaining) = 0.79 x (16)² x 21

V(remaining) = 4247 cubic unit

The constant c that makes f(x,y) a joint pmf for X and Y is c = 1/18.

For f(x,y) to be a joint pmf, it must satisfy the following two conditions:

The sum of f(x,y) over all possible values of x and y must be equal to 1.

f(x,y) must be non-negative for all possible values of x and y.

Let's first find the value of c that satisfies condition 2:

Since Sx=(1,2) and Sy=(1,2,3), the possible values of (x,y) are:

(1,1), (1,2), (1,3), (2,1), (2,2), (2,3)

We need to ensure that f(x,y) is non-negative for all of these possible values. This means that:

c(x+2y) ≥ 0

Since x and y are both non-negative integers, the expression inside the parentheses can never be negative. Therefore, we just need to make sure that c is non-negative. If c is negative, then f(x,y) will be negative for some values of x and y, which violates condition 2.

Now let's find the value of c that satisfies condition 1:

We need to find the sum of f(x,y) over all possible values of x and y, and set it equal to 1:

ΣΣ f(x,y) = 1

Σx=1,2 Σy=1,2,3 c(x+2y) = 1

cΣx=1,2 Σy=1,2,3 (x+2y) = 1

c(1+2+3+2+4+6) = 1
