P(A and B) = [?]
The probability of event A and event B is 6.
Given that, P(A)=6, P(B)=20 and P(A∩B)=6.
P(A/B) Formula is given as, P(A/B) = P(A∩B) / P(B), where, P(A) is probability of event A happening, P(B) is the probability of event B.
P(A/B) = P(A∩B) / P(B) = 6/20 = 3/10
We know that, P(A and B)=P(A/B)×P(B)
= 3/10 × 20

The length of a rectangle is one less than 3
times the width. The area is 70 m sq. What
are the length and width?
Answer:
l= 10 , w=7
Step-by-step explanation:
If the length of a rectangle is 11 m less than 3 times the width, then we can come up with this equivalency:
l = 3w - 11
where l stands for length and w stands for width. Now we plug in the equivalency into the equation for the area of a rectangle:
A = lw
A = (3w - 11)w
70 = (3w - 11)w
70 = 3w2 - 11w
Then solve for w by completing the square. Now, in order to complete the square for this, we need to find a completion that fits 3w2 - 11w + ? and completes the base factoring of (√(3)w - ? )2. The only one that fits the second question mark so that it can work out to the first is (11√3)/6, and when we work it into the first question mark, the first question mark becomes 121/12. Essentially, what we have for completing the square is:
70 + 121/12 = 3w2 - 11w + 121/12
80.08333 = (√(3)w - (11√3)/6)(√(3)w - (11√3)/6)
80.08333 = (√(3)w - (11√3)/6)2
8.94893 = √(3)w - (11√3)/6
Solving for w, we get:
12.124 = √(3)w
w = 7
Since we know that the length is 11 m less than 3 times the width, we can plug w into the first equation to find l:
l = 3w - 11
l = 3(7) - 11
l = 21 - 11
l = 10
And if we want to check, lw = (10)(7) = 70.
How do you write an equation for a parabola with the vertex and Y intercept?
To write an equation for a parabola with the vertex and y-intercept, the equation of vertex form y=a(x-h)^2+k is used.
What is a parabola?
A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves.
Consider an example where vertex is (2,1) and y-intercept is (0,-3).
The equation of parabola needs to be deduced using these points.
The equation of a parabola in vertex form is -
y=a(x-h)^2+k
Here, a is a constant and (h ,k) are the coordinates of the vertex.
So, (h,k)=(2,1)
⇒y=a(x−2)^2+1
To obtain the value of a, substitute (0,−3) into the equation -
-3=4a+1
4a=-4
a=-1
⇒y=-1(x−2)^2+1
Now, distribute and simplify -
y=-1(x−2)^2+1
y=-(x^2-4x+4)+1
y=-x^2+4x-4+1
y=-x^2+4x-3
On, graphing this equation a parabola is obtained.
Therefore, to write an equation of parabola vertex form is used.

If he requires 2 ¾ cans of paint for each wall and a can of paint costs 3 ⅛ dollars, how much will Mason spend on paint?
a) The area of each of the walls is 60 feet².
b) The combined area of the four walls is 240 feet².
c) The total cost Mason will spend on paint is $34.375.
What is the area?The area refers to the space occupied by two-dimensional objects.
We can compute the area by multiplying the length by the width.
Areas are stated in square units.
Length of each wall = 6 ⅖ feet
Width of each wall = 9 ⅜ feet
The area of each wall = 60 feet² (6 ⅖ feet x 9 ⅜ feet).
The combined area of the walls = 240 feet² (60 ft² x 4).
The number of cans of paint required for each wall = 2¾ cans.
The cost per can of paint = 3⅛ dollars or $3.125.
The total cost of paint = $34.375 (4 x 2¾ x $3⅛).

Construct a 95% confidence interval for the expected difference in average test scores between the small class (Classroom A) and the regular class (Classroom B),
a. You can follow these steps:
1. Refer to column (4) of Table 13.2 and find the results for the regressors.
2. Calculate the standard error of the difference in average test scores using the formula:
SE(difference) = sqrt[SE(Classroom A)^2 + SE(Classroom B)^2]
where SE(Classroom A) and SE(Classroom B) are the standard errors for each class.
3. Calculate the margin of error (ME) by multiplying the critical value (z*) corresponding to a 95% confidence level by the standard error (SE).
4. Finally, construct the confidence interval by subtracting the margin of error from the difference in average test scores and adding it to the difference in average test scores.

Consider the same firm with production function: q=f(L,K) = 20L +25K+5KL-0.03L² -0.02K² Make a diagram of the total product of labour, average product of labour, and marginal product of labour in the short run when K = 5. (It is ok if this diagram is not to scale.) Does this production function demonstrate increasing marginal returns due to specialization when L is low enough? How do you know?
The MP curve initially rises to its maximum value because of the specialized nature of the fixed capital, where each additional worker's productivity rises due to the marginal product of the fixed capital.
Production Function: q = f(L,K) = 20L + 25K + 5KL - 0.03L² - 0.02K²
Given, K = 5, i.e., capital is fixed. Therefore, the total product of labor, average product of labor, and marginal product of labor are:
TPL = f(L, K = 5) = 20L + 25 × 5 + 5L × 5 - 0.03L² - 0.02(5)²
= 20L + 125 + 25L - 0.03L² - 5
= -0.03L² + 45L + 120
APL = TPL / L, or APL = 20 + 125/L + 5K - 0.03L - 0.02K² / L
= 20 + 25 + 5 × 5 - 0.03L - 0.02(5)² / L
= 50 - 0.03L - 0.5 / L
= 49.5 - 0.03L / L
MP = ∂TPL / ∂L
= 20 + 25 - 0.06L - 0.02K²
= 45 - 0.06L
The following diagram illustrates the TP, MP, and AP curves:
Figure: Total Product (TP), Marginal Product (MP), and Average Product (AP) curves
The production function demonstrates increasing marginal returns due to specialization when L is low enough, i.e., when L ≤ 750. The marginal product curve initially increases and reaches a maximum value of 45 units of output when L = 416.67 units. When L > 416.67, MP decreases, and when L = 750 units, MP becomes zero.
The MP curve's initial increase demonstrates that the production function displays increasing marginal returns due to specialization when L is low enough. This is because when the capital is fixed, an additional unit of labor will benefit from the fixed capital and will increase production more than the previous one.
In other words, Because of the specialised nature of the fixed capital, the MP curve first climbs to its maximum value, where each additional worker's productivity rises due to the marginal product of the fixed capital.
The APL curve initially rises due to the MP curve's increase and then decreases when MP falls because of the diminishing marginal returns.

One of the chair lifts at a ski resort unloads 1700 skiers per hour at the top of the slope. The ride from the bottom to the top takes 15 minutes. How many skiers are riding on the lift at any given time?
For the given question there are always 425 skiers on the chair lift at any given time.
The chair lift unloads 1700 skiers per hour at the top of the slope. The ride from the bottom to the top takes 15 minutes. We have to determine the number of skiers who are riding on the lift at any given time.
There are a few steps that we can take to solve this problem:
Step 1:Calculate how long the trip is from top to bottom:
The trip from bottom to top takes 15 minutes.
Therefore, the trip from top to bottom would take the same amount of time.
Step 2:Calculate how many trips the lift makes in an hour:
We have to convert 1 hour to minutes.1 hour = 60 minutes
Therefore, 1 hour = 60/15 = 4 trips from top to bottom
Step 3:Calculate how many skiers are riding on the lift at any given time.
The chair lift unloads 1700 skiers per hour at the top of the slope.
So, every 15 minutes, 425 skiers are unloaded at the top.
Since the lift takes 15 minutes to make one trip, there are always 425 skiers on the lift at any given time.
There are always 425 skiers on the chair lift at any given time.

If xn>0 for all nN, and lim (xn)=0, then lim(√(xn))=0
We know that the limit of a sequence is unique. Since lim(xn) = 0, we have that for every ε > 0, there exists an N ∈ ℕ such that for all n ≥ N, we have |xn - 0| < ε, which implies xn < ε. Now, consider the sequence √(xn). Since xn > 0 for all n ∈ ℕ, we can take the square root of both sides of the inequality xn < ε. This gives us:
√(xn) < √(ε).
Since ε > 0 can be arbitrarily small, it's clear that lim(√(xn)) = 0, as for every ε > 0, there exists an N such that for all n ≥ N, we have √(xn) < √(ε).
Given the conditions that xn > 0 for all n ∈ N and lim(xn) = 0, we have shown that lim(√(xn)) = 0.

A jogger runs around a circular track of radius 75 ft. Let be her coordinates, where the origin is the center of the track. When the jogger's coordinates are (45, 60), her -coordinate is changing at a rate of ft/s. Find .
The rate at which the y-coordinate of the jogger is changing is \({-\frac{3}{4}}\) times the rate at which the x-coordinate of the jogger is changing.
Given information:
Radius of the circular track = 75 ft
Coordinates of the jogger: (45, 60)
We know that the coordinates of a point in the Cartesian plane can be represented as (x, y), where x represents the horizontal displacement and y represents the vertical displacement.
Let us now consider a jogger who runs around a circular track of radius 75 ft, with the center of the track being the origin. Therefore, the horizontal and vertical displacements of the jogger will be its coordinates, respectively.
Let us now consider a right-angled triangle with the hypotenuse representing the radius of the circular track, and the vertical and horizontal sides representing the y and x coordinates of the jogger, respectively. Since the radius of the circular track is constant, we can use the Pythagorean theorem to relate x and y.
Since we know that the radius of the track is 75 ft, we can say that:
\(\[x^2 + y^2 = 75^2\]\)
Differentiating with respect to time t, we get:
\(\[\frac{d}{dt}(x^2 + y^2)\)
= \(\frac{d}{dt}(75^2)\]\\\2x \cdot \frac{dx}{dt} + 2y \cdot \frac{dy}{dt} = 0\]\)
Now, since we are given that the jogger's coordinates are (45, 60), we can substitute these values to obtain:
\(\[2(45) \cdot \frac{dx}{dt} + 2(60) \cdot \frac{dy}{dt} = 0\]\)
On solving, we obtain:
\(\[\frac{dy}{dt} = -\frac{3}{4}\cdot \frac{dx}{dt}\]\)
Hence, the rate at which the y-coordinate of the jogger is changing is \({-\frac{3}{4}}\) times the rate at which the x-coordinate of the jogger is changing.

a) The value of y₁(t) can be found by evaluating t₃ at t = 2, which gives y₁(t) = 8.
(b) The value of y₂(t) can be found by evaluating cos(t) at t = π/3, which gives y₂(t) = cos(π/3) = 1/2.
(c) The value of y₃(t) can be found by evaluating -1 - 3t₅ at t = 2, which gives y₃(t) = -1 - 3(2)^5 = -193.
The sampling property of impulses states that when an impulse function δ(t - a) is multiplied with a function f(t), the value of f(t) at t = a is obtained. Using this property, we can compute the given integrals involving impulse functions.
(a) For y₁(t), we have y₁(t) = ∫(t³ * δ(t - 2)) dt. Since δ(t - 2) is non-zero only when t = 2, we evaluate t³ at t = 2, giving y1(t) = 2³ = 8.
(b) For y₂(t), we have y₂(t) = ∫(cos(t) * δ(t - π/3)) dt. Since δ(t - π/3) is non-zero only when t = π/3, we evaluate cos(t) at t = π/3, giving y₂(t) = cos(π/3) = 1/2.
(c) For y₃(t), we have y₃(t) = ∫((-1 - 3t⁵) * δ(t - 2)) dt. Since δ(t - 2) is non-zero only when t = 2, we evaluate (-1 - 3t⁵) at t = 2, giving y₃(t) = -1 - 3(2)⁵ = -193.
Therefore, the values of y₁(t), y₂(t), and y₃(t) are 8, 1/2, and -193, respectively.
