b) The following table provides information about production at the XYZ-TV Company. Number of Workers TVs Produced 0 0 1 35 2 68 3 99 4 128 5 155 How many workers will the XYZ-TV Company hire if the going wage for TV production workers is $16,000? Show your calculation in detail.
Answer:
5
Step-by-step explanation:
Given the following :
Number of workers - - TVs produced
0 - - - - - - - - - - - - - - - - - 0
1 - - - - - - - - - - - - - - - - - - 35
2 - - - - - - - - - - - - - - - - - 68
3 - - - - - - - - - - - - - - - - - - 99
4 - - - - - - - - - - - - - - - - - - 128
5 - - - - - - - - - - - - - - - - - - 155
We need to calculate the marginal product :
Workers - - - marginal product - - - value of m/p
0 - - - - - - - - - - - ____ - - - - - - - - - - - - - - __
1 - - - - - - - - - - - 35 (35 - 0) - - - - - - 35000
2 - - - - - - - - - - - - 33 (68 - 35) - - - - 33000
3 - - - - - - - - - - - - 31 (99 - 68) - - - - - 31000
4 - - - - - - - - - - - - 29 (128 - 99) - - - - - 29000
5 - - - - - - - - - - - - 27 (155 - 128) - - - 27000
The marginal product shows the change in output due to one additional unit of a certain input of production, in this case, number of workers. If the going wage of workers is $16,000, the company can afford to hire up to 5 workers and still make profit.
Limit (sin4x-4sinx)/x^3 when x close to zero
[tex]\Large \boxed{\sf \bf \ \ \lim_{x\rightarrow0} \ {\dfrac{sin(4x)-4sin(x)}{x^3}}=-10 \ \ }[/tex]
Step-by-step explanation:
Hello, please consider the following.
Using Maclaurin series expansion, we can find an equivalent of sin(x) in the neighbourhood of 0.
[tex]sin(x) \sim \left(x-\dfrac{x^3}{3!}\right)\\\\\text{So, in the neighbourhood of 0}\\\\\begin{aligned}(sin(4x)-4sin(x)) &\sim \left( 4x-\dfrac{(4x)^3}{3!}-4x+\dfrac{4x^3}{3!}\right)\\\\&\sim \left(\dfrac{x^3*4*(1-4^2)}{3*2}\right)\\\\&\sim \left(\dfrac{x^3*2*(-15)}{3}\right)\\\\&\sim \left(x^3*2*(-5)\right)\\\\&\sim \left(x^3*(-10)\right)\\\end{aligned}[/tex]
Then,
[tex]\displaystyle \lim_{x\rightarrow0} \ {\dfrac{sin(4x)-4sin(x)}{x^3}}\\\\= \lim_{x\rightarrow0} \ {\dfrac{-10*x^3}{x^3}}\\\\=-10[/tex]
Thank you
Answer:
-10
Step-by-step explanation:
L' Hopital's rule can be used to solve it.
We search for lim (f(x)/g(x))
this is the same as lim (f' (x)/g' (x))
this is the same as lim f'' (x)/g'' (x)
so here we have f(x) =sin(4x)-4sin(x)
g(x)=x^3
g'' (x)= 6x
f'' (x)=-16sin(4x)+4sin(x)
so lim f'' (x) / g ''(x) = -16/6 lim sin(4x)/x + 4/6 lim (sin(x)/x)
= -16*4/6+4/6
=(-64+4)/6=-60/6=-10

I need the slope-intercept form equation for the line shown in the graph
Answer: y=-8/5x+2
Step-by-step explanation:
The equation for slope-intercept form is y=mx+b. We know that m is the slope and b is the y-intercept. We can determine that b=2 because the y-intercept passes through the y-axis. This line passes through the y-axis at y=2. Now, all we have to do is find the slope. We can do that by using any two points on the graph. Let's use (-5,10) and (5,-6). The formula for slope is [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].
[tex]m=\frac{-6-10}{5-(-5)} =\frac{-16}{10} =-\frac{8}{5}[/tex]
With our slope, we can piece together the slope-intercept form equation.
y=-8/5x+2
What is the following lines is not parelle of y=4x+7
Answer: 4y - x = 8
y = 4x + 7
This equation is in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. The slope of this line is 4. Parallel lines have the same slope, thus a line not parallel to this line will not have a slope of 4. Let's check which of these lines does not have a slope of 4.
y - 4x = 9
y = 9 + 4x (add 4x to both sides)
y = 4x + 9 (switch the constant and x-term)
This line has a slope of 4.
4x - y = 8
-y = 8 - 4x (subtract 4x from both sides)
y = -8 + 4x (divide both sides by -1)
y = 4x - 8 (switch the constant and x-term)
This line has a slope of 4.
4y - x = 8
4y = 8 + x (add x to both sides)
y = 8/4 + x/4 (divide both sides by 4)
y = x/4 + 2 (simplify and switch constant and x-term)
This line has a slope of 1/4. It is thus not parallel to the line y = 4x + 7.
Answer: 4y - x = 8

Complete Question
Professor Jin wants to travel from place A to place B without a map. There are four ways lead away from place A. If road I is selected, the probability of arriving place B is 1/8; if road II is selected, the probability of arriving place B is 1/6; if road III is selected, the probability of arriving place B is 1/4; and if road IV is selected,the probability of arriving place B is 9/10.
(a) What is the probability that professor will arrive at place B?
(b) If Professor Jin arrives at place B, what is the probability that she chooses road IV?
Answer:
a
[tex]P(B) = 0.36[/tex]
b
[tex]P(4 /B) = 0.62[/tex]
Step-by-step explanation:
From the question we are told that
The number of ways from A to B is n = 4
The probability if road 1 is selected is [tex]P(1) = \frac{1}{8}[/tex]
The probability if road 2 is selected is [tex]P(2) = \frac{1}{6}[/tex]
The probability if road 3 is selected is [tex]P(3) = \frac{1}{4}[/tex]
he probability if road 4 is selected is [tex]P(4) = \frac{9}{10}[/tex]
The probability that professor will arrive at place B is mathematically represented as
[tex]P(B) = \frac{1}{n} * P(1) + \frac{1}{n} * P(2) + \frac{1}{n} * P(3)+ \frac{1}{n} * P(4)[/tex]
[tex]P(B) = \frac{1}{4} * \frac{1}{8} + \frac{1}{4} * \frac{1}{6} + \frac{1}{4} * \frac{1}{4} + \frac{1}{4} * \frac{9}{10}[/tex]
[tex]P(B) = 0.36[/tex]
If Professor Jin arrives at place B, what is the probability that she chooses road IV is mathematically represented as
[tex]P(4 /B) = \frac{ \frac{1}{n} * P(4)}{P(B)}[/tex]
=> [tex]P(4 /B) = \frac{ \frac{1}{4} * \frac{9}{10} }{0.36}[/tex]
=> [tex]P(4 /B) = 0.62[/tex]

The sum of two numbers is twenty-five. One number is five less than the other.
Answer: x=15, y=10
*Note: x and y are only variables used to solve this problem, but know that the two numbers are 15 and 10.
Step-by-step explanation:
For this problem, we can use system of equations. Let's use x for one number and y for the other.
First Equation:
x+y=25
We get this equation because it states that the sum of the two numbers is 25.
Second Equation:
y=x-5
We get this equation because it says one number (y) is 5 less than the other (x).
Since we have two equations, we can use substitution method to solve.
[tex]x+(x-5)=25[/tex] [distribute 1 to (x-5)]
[tex]x+x-5=25[/tex] [combine like terms]
[tex]2x-5=25[/tex] [add both sides by 5]
[tex]2x=30[/tex] [divide both sides by 2]
[tex]x=15[/tex]
Now that we have x, we can plug it into any of the equations to find y.
[tex]x+y=25[/tex] [plug in x=15]
[tex]15+y=25[/tex] [subtract both sides by 15]
[tex]y=10[/tex]
Finally, we have our answer, x=15 and y=10.

Answer:i
i) 7/15
ii) 7/15
Step-by-step explanation:
total: 10
good: 7
bad: 3
i) both are good
p(both good) = 7/10 * 6/9 = 42/90 = 7/15
ii) one good & one bad
p(first good & second bad) = 7/10 * 3/9 = 21/90 = 7/30
p(first bad & second good) = 3/10 * 7/9 = 21/90 = 7/30
p(one good & one bad) = 7/30 + 7/30 = 14/30 = 7/15

3. If mZEFH = (5x + 1), mZHFG = 62°, and
mZEFG = (18x + 11), find each measure.
Answer/Step-by-step explanation:
Given:
m<EFH = (5x + 1)°
m<HFG = 62°
m<EFG = (18x + 11)°
Required:
1. Value of x
2. m<EFH
3. m<EFG
SOLUTION:
1. Value of x
m<EFH + m<HFG = m<EFG (angle addition postulate)
(5x + 1) + 62 = (18x + 11)
Solve for x using this equation
5x + 1 + 62 = 18x + 11
5x + 63 = 18x + 11
Subtract 18x from both sides
5x + 63 - 18x = 18x + 11 - 18x
-13x + 63 = 11
Subtract 63 from both sides
-13x + 63 - 63 = 11 - 63
-13x = -52
Divide both sides by -13
-13x/-13 = -52/-13
x = 4
2. m<EFH = 5x + 1
Plug in the value of x
m<EFH = 5(4) + 1 = 20 + 1 = 21°
3. m<EFG = 18x + 11
m<EFG = 18(4) + 11 = 72 + 11 = 83°

B) There is NOT sufficient evidence to conclude the proportion of work time linguists study a new language is more than 10%.
C) There is sufficient evidence to conclude the proportion of work time linguists study a new language is more than 90%.
D) There is NOT sufficient evidence to conclude the proportion of work time linguists study a new language is more than 90%.
Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The null hypothesis is [tex]H_o : p = 0.10[/tex]
The alternative hypothesis is [tex]H_a : p > 0.10[/tex]
The p-value is [tex]p-value = 0.09[/tex]
The level of significance is [tex]\alpha = 0.025[/tex]
From the given values [tex]p-value > \alpha[/tex] so we fail to reject the null hypothesis
So there is NOT sufficient evidence to conclude the proportion of work time linguists study a new language is more than 10%.

A whale that is 460 feet below sea level rises up and breaches out of water to a height of 27 feet above sea level. What is the vertical distance the whale travels.
Answer:
487ftStep-by-step explanation:
Let the initial point of of the sea level be 0. If the whale was initially 460 feet below sea level, then its distance from the surface of sea level to the 460ft below the sea level will be 460 - 0 = 460ft.
Also, if the whale rises up and breaches out of water to a height of 27 feet above sea level, then its distance from the surface of sea level to the 27ft above the sea level will be 0 - 27 = 27ft.
The vertical distance that the whale travels = distance from the sea level to 460ft below the sea level + distance from the sea level to 27ft above the sea level
The vertical distance that the whale travels = 460ft + 27ft
The vertical distance that the whale travels = 487ft
There are n machines in a factory, each of them has defective rate of 0.01. Some maintainers are hired to help machines working. Using Poisson approximations to answer the following questions and explain why we can use Poisson approximation.
(a) If one maintainer is responsible for 20 machines, what’s the probability that machines go defective and cannot be repaired on time?
(b) If three maintainers are responsible for 80 machines, what’s the probability that machines go defective and cannot be repaired on time?
(c) Assume n=300, then at least how many maintainers are required such that the probability machines cannot be fixed on time is less than 0.01?
Answer:
a) 1 - ∑²⁰ˣ_k=0 ((e^-λ) × λ^k) / k!
b) 1 - ∑^(80x/d)_k=0 ((e^-λ) × λ^k) / k!
c) ∑²⁰ˣ_k=0 (3^k)/k! = 0.99e³
Step-by-step explanation:
Given that;
if n ⇒ ∞
p ⇒ 0
⇒ np = Constant = λ, we can apply poisson approximation
⇒ Here 'p' is small ( p=0.01)
⇒ if (n=large) we can approximate it as prior distribution
⇒ let the number of defective items be d
so p(d) = ((e^-λ) × λ) / d!
NOW
a)
Let there be x number of repairs, So they will repair 20x machines on time. So if the number of defective machine is greater than 20x they can not repair it on time.
λ[n0.01]
p[ d > 20x ] = 1 - [ d ≤ 20x ]
= 1 - ∑²⁰ˣ_k=0 ((e^-λ) × λ^k) / k!
b)
Similarly in this case if number of machines d > 80x/3;
Then it can not be repaired in time
p[ d > 80x/3 ]
1 - ∑^(80x/d)_k=0 ((e^-λ) × λ^k) / k!
c)
n = 300, lets do it for first case i.e;
p [ d > 20x } ≤ 0.01
1 - ∑²⁰ˣ_k=0 ((e^-λ) × λ^k) / k! = 0.01
⇒ ∑²⁰ˣ_k=0 ((e^-λ) × λ^k) / k! = 0.99
⇒ ∑²⁰ˣ_k=0 (λ^k)/k! = 0.99e^λ
∑²⁰ˣ_k=0 (3^k)/k! = 0.99e³
BD bisects ∠ABC. Find m∠ABD and m∠CBD.
Answer:
angle ABD=1/2 angle ABC ,Angle CBD =1/2 angleCBD
Step-by-step explanation:
The measure of angles ∠ABD= 67°, m∠CBD= 67° and m∠ABC= 134°.
We have,
BD bisects the angle ABC makes two equal halves angle.
So, < ABD= < CBD.
and ∠ABD= (8x + 35)°
∠CBD= (11x + 23)°
Substituting the values of the angles
(8x + 35)° = (11x + 23)°
35-23 = 11x- 8x
3x= 12
x= 4.
Putting x=4 in (i) we have,
∠ABD= 8(4) + 35
∠ABD= 67°
As ∠ABD = ∠CBD,
∠CBD= 67°
Now, ∠ABC= ∠ABD + ∠CBD
∠ABC= 67° + 67°
∠ABC= 134°.
Hence, the measure of m∠ABD= 67°, m∠CBD= 67° and m∠ABC= 134°.

Answer:
the marked choice is correct
Step-by-step explanation:
It usually works well to follow directions: use technology. The attachment shows the use of the technology I like for short regression problems. For longer problems, a spreadsheet program is a good choice.
_____
In this problem, it is easy to eliminate the nonsensical answers, so no real use of technology is necessary.
First of all, the y-value for x=0 needs to be near 48, eliminating the last two choices.
Second, the minimum of the function corresponds to a positive x-value, so the coefficient of the x-term must have opposite sign from the coefficient of the x^2 term. This eliminates the second choice, leaving the marked choice as the only viable one.
Grace had $51 when she browsed an on-line store, which sells a pair of green earrings for $9.00 each plus a one-time $6.00 shipping charge. How many pairs of green earrings did Grace purchase? Solve the equation for the situation.
Answer:
5 Green earrings
Step-by-step explanation:
Given that:
Total amount held = $51
Cost per pair of green earrings = $9
One time shipping fee = $6
How many pairs of green earrings did grace purchase?
Let the number of green earrings purchased = g
Then,
$9*g + $6 = $51
$9g + $6 = $51
$9g = $51 - $6
$9g = $45
g = $45 / $9
g = 5
Hence, the number of green earrings purchased = 5
