A uniform continuous distribution has a maximum of 14 and a minimum of 2. Samples of size 36 are drawn from the distribution. What is the variance of the sample means?.
Answers
The variance of the sample mean is 12/35 = 0.3429.. This is a result of uniform distribution.
The uniform distribution is a continuous probability distribution and is concerned with events that are equally likely to occur. When working out problems that have a uniform distribution, be careful to note if the data is inclusive or exclusive.
According to the question, we have
Sample size (n) = 36; uniform continuous distribution has a maximum of 14 and a minimum of 2.
The notation for the uniform distribution is
X U(a,b), where a= the lowest value of x and b= the highest value of x. The probability density function is f(x) = 1/(ba ) fo axb .
b = 14 and a = 2.
Variance in uniform distribution = (b-a)² / 12.
Put the value of a and b,
Variance = ( 14-2)²/12 = 12
Sample variance is used to calculate the variability of sample sets.
The variance of the sample means = variance / (sample size- 1) 9= (b-a)²/ (n-1)
= 12/35= 0.342

The distance of a golf ball from the hole can be represented by the right side of a parabola with vertex (-1,8). The ball reaches the hole 1 second after it is hit. What is the equation of the parabola, in vertex form, that represents the ball's distance, y, from the hole, x seconds after the ball is hit?
Answers
The equation of the parabola, in vertex form, that represents the ball's distance, y, from the hole, x seconds after the ball is hit is
y = (-2m/s²)t² + (-2m/s)t + 6m.
Given:
Let's assume that the hole is at y = 0m, with x seconds as the time.
The vertex of the parabola can be written as (-1s, 8m) where the time variable, x, is supposed to be in seconds, while the distance variable, y, is supposed to be in meters.
The ball reaches the hole at x = 1s, so we have point (1s, 0m)
The vertex of the parabola y = ax² + bx + c is known to be at
x = -b/2a,
So, -1 = -b/2a
We have the following equations,
8m = a(-1s)² + b(-1s) + c
0m = a*(1s)² + b(1s) + c
-1s = -b/2a
b = 2a × 1s
Substituting the value of b in the equations and simplifying them,
8m = a×1s² - 1s×2a×1s + c
⇒ 8m = a( 1s² - 2s²) + c = -a×1s² + c.
0m = a×1s² + 1s×2a×1s + c
⇒ 0m = a(1s² + 2s²) + c = a×3s² + c
Deriving the value of c from the second equation we put it in the first equation,
c = - a×3s²
The first equation is as,
8m = -a×1s² - a×3s² = -a×4s²
a = 8m/-4s² = -2m/s²
From the value of a we can calculate the values of b and c.
c = -a×3s² = -(-2m/s²)×3s²= 6m.
b = 1s×2a = 1s×(-2m/s²) = -2m/s.
Then the equation is:
y = (-2m/s²)t² + (-2m/s)t + 6m

chegg a 12 ft ladder is leaning against a wall. if the top of the ladder slides down the wall at a rate of 4 ft/s, how fast (in ft/s) is the bottom moving along the ground when the bottom of the ladder is 6 ft from the wall?
Answers
The bottom is moving at a rate of [tex]4\sqrt{3}[/tex] ft/s along the ground when the botton of the ladder is at a distance of 6 ft from the wall.
Here we have been mentioned that a 12 feet ladder is leaning against the wall which is represened by AC in the below given triangle.
We have AB = y = distance of top of the ladder from the wall
BC = x = distance of bottom of the ladder from the wall
AC = z = height of the ladder = 12 ft (given)
The top of the ladder AB is sliding down at a rate of 4 [tex]ft/s[/tex]
∴ [tex]\frac{dy}{dt}[/tex] = - 4 ft/s (negative sign indicates that the top is sliding downwards)
Let the rate at which the bottom of the ladder is sliding be [tex]\frac{dx}{dt}[/tex]
Now in the right angled triangle [tex]ABC[/tex] by using Pythagoras theorem we have,
[tex]AB^{2} + BC^{2} =[/tex][tex]AC^{2}[/tex]
[tex]y^{2} +x^{2} = z^{2}[/tex] (equation 1)
When x = 6ft and z = 12 ft,
[tex]y^{2} +6^{2} = 12^{2}[/tex]
⇒ [tex]y^{2} = 144 - 36[/tex]
⇒ [tex]y^{2} = 108[/tex]
⇒ y = √108
⇒ y = 6 √3 ft
Differentiating equation 1 with respect to [tex]time[/tex] we get,
[tex]\frac{d}{dt} (y^{2} +x^{2} ) = \frac{d}{dt} (z^{2})[/tex]
⇒ 2y[tex]\frac{dy}{dt}[/tex] + 2x[tex]\frac{dx}{dt}[/tex] = 2z[tex]\frac{dz}{dt}[/tex]
Putting the values of dz/dt = 0 (as the height is constant) , dy/dt = - 4 ft/s , y = 6 √3 ft, x = 6ft and z = 12ft we have,
∴ 2(6√3) (-4) + 2(6)[tex]\frac{dx}{dt}[/tex] = 2(12)(0)
⇒ -48√3 + 12[tex]\frac{dx}{dt}[/tex] = 0
⇒ 12[tex]\frac{dx}{dt}[/tex] = 48√3
⇒ [tex]\frac{dx}{dt} = \frac{48\sqrt{3} }{12}[/tex]
⇒ [tex]\frac{dx}{dt} = 4\sqrt{3}[/tex] ft/s
Hence the rate at which the bottom of the ladder is sliding is [tex]\frac{dx}{dt} = 4\sqrt{3}[/tex] ft\s

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:
f(d) = 7(1.06)d
Part A: When the biologist concluded her study, the radius of the algae was approximately 13.29 mm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(d) represent? (2 points)
Part C: What is the average rate of change of the function f(d) from d = 4 to d = 11, and what does it represent? (4 points)
Answers
From the given function, it is found that:
a. A reasonable domain for the function is of 0 ≤ d ≤ 11.
b. The y-intercept of the graph represents that the initial radius of the algae is of 7 mm.
c. The average rate of change between the 4th and the 11th day of the function means that the radius of the algae grew by an average of 0.64 mm a day.
What does the function represent?The function is modeled according to the following rule:
f(d) = 7(1.06)^d
In which:
d is the number of days.f is the radius of the algae.When the biologist concluded her study, the radius of the algae was approximately 13.29 mm, hence the upper bound of the domain is found as follows:
[tex]13.29 = 7(1.06)^d[/tex]
[tex](1.06)^d = \frac{13.29}{7}[/tex]
[tex]\log{(1.06)^d} = \log{\left(\frac{13.29}{7}\right)}[/tex]
[tex]d\log{1.06} = \log{\left(\frac{13.29}{7}\right)}[/tex]
[tex]d = \frac{\log{\left(\frac{13.29}{7}\right)}}{\log{1.06}}[/tex]
d = 11.
The smallest possible number of days is of 11, hence a reasonable domain for the function is:
0 ≤ d ≤ 11.
The y-intercept of the graph represents that the initial radius of the algae, as it is calculated when d = 0, hence it's value is given by:
[tex]f(0) = 7(1.06)^0 = 7[/tex]
The average rate of change of a function is given by the change in the output divided by change in the input, hence:
[tex]f(11) = 7(1.06)^{11} = 13.29[/tex][tex]f(4) = 7(1.06)^{4} = 8.84[/tex]r = (13.29 - 8.84)/(11 - 4) = 0.64 mm a day.

According to function theory, there are five operations between two functions to create resulting functions:
Addition - f(x) + g(x) = (f + g) (x).Subtraction - f(x) - g(x) = (f - g) (x).Multiplication - f(x) · g(x) = (f · g) (x).Division - f(x) / g(x) = (f / g) (x).In this problem we must use the operation of multiplication between two functions.
Case 1
(f · g)(x) = (2 · x + 4) · (x² + 4 · x + 4)
(f · g)(x) = (2 · x + 4) · x² + 4 · (2 · x + 4) · x + 4 · (2 · x + 4)
(f · g)(x) = 2 · x³ + 4 · x² + 8 · x² + 16 · x + 8 · x + 16
(f · g)(x) = 2 · x³ + 12 · x² + 24 · x + 16
Case 2
(h · g)(x) = (x² - 4) · (x² + 4 · x + 4)
(h · g)(x) = (x² - 4) · x² + (x² - 4) · (4 · x) + (x² - 4) · 4
(h · g)(x) = x⁴ - 4 · x² + 4 · x³ - 16 · x + 4 · x² - 16
(h · g)(x) = x⁴ + 4 · x³ - 16 · x - 16
Case 3
(f · h)(x) = (2 · x + 4) · (x² - 4)
(f · h)(x) = 2 · x³ - 8 · x + 4 · x² - 16
(f · h)(x) = 2 · x³ - 4 · x² - 8 · x - 16
(f · h)(2) = 2 · 2³ - 4 · 2² - 8 · 2 - 16
(f · h)(2) = - 32
Case 4
(g · f)(x) = (x² + 4 · x + 4) · (2 · x + 4)
(g · f)(x) = 2 · x³ + 12 · x² + 24 · x + 16
Case 5
(g · h)(x) = (x² + 4 · x + 4) · (x² - 4)
(g · h)(x) = x⁴ + 4 · x³ - 16 · x - 16
Case 6
(f · h)(x) = (2 · x + 4) · (x² - 4)
(f · h)(x) = 2 · x³ - 4 · x² - 8 · x - 16
Case 7
(h · g)(x) = (x² - 4) · (x² + 4 · x + 4)
(h · g)(x) = x⁴ + 4 · x³ - 16 · x - 16
(h · g)(1) = 1⁴ + 4 · 1³ - 16 · 1 - 16
(h · g)(1) = - 27
