Answer:
Below in bold.
Step-by-step explanation:
(a) y=x^2sin2x
Using the Product Rule:
dy/dx = x^2*2cos2x + 2xsin2x
dy/dx = 2x(xcos2x + sin2x).
(b) y=ln sqrt(1+t^2)
y = ln (1 + t^2)^1/2
Using the chain rule:
dy/dx = 1 / (1 + t^2)^1/2 * 1/2(1 + t^2)^-1/2 * 2t
= 2t/(1 + t^2)^1/2 * 1/ (2(1 + t^2)^1/2
= 2t / 2(1 + t^2)
= t / ( 1 + t^2).

A clothing manufacturer would like to determine whether celebrity endorsements and length of commercial influence a customer's decision to buy its products. In order to estimate this potential influence, the manufacturer premieres its latest series of commercials privately to potential buyers. There are two types of commercials: commercials without celebrities, and commercials with celebrities. There are two lengths of commercials: 30 seconds and 60 seconds. Each potential buyer is randomly assigned a type and length of commercial to view. What are the factors of interest to the manufacturer
Answer:
The correct response will be "whether or not the viewer will buy the product".
Step-by-step explanation:
To consider its clients, the manufacturer requires conducting this research, but the only element of interest would be to figure out whether or not the consumer purchases the product after seeing the ad. The response variable or perhaps the predictor variables determine "not if the audience can buy the advertisement" as well as "whether another advertisement becomes 30 or 60 seconds" including "not when the commercial involves a brand personality" have become the explanatory variables or even just the relationship between the independent variable.Joseph earned $53 the first week he worked at Jim’s Candy Store and $62 the next week.

1. What is the difference between a line and a line segment?
A. A line is a figure formed by two opposite rays with a shared endpoint, a line segment is a part of
a line that extends forever in one direction.
B. A line is a specific location that is represented by a dot, a line segment is a specific location
represented by two dots.
C. Aline is a portion of a line consisting of two points and all the points between them, and a line
segment is a figure formed by two opposite rays.
D. Aline is a figure formed by two opposite rays and a shared endpoint, and a line segment is a
portion of a line consisting of two points and all the points between them.
Explanation:
Basically a line goes on forever in both directions. A ray only goes off forever in one direction. If we glue together two rays that point in complete opposite directions (eg 1 points north, the other points south) then we form a line.
A line segment is a piece of a line. It doesn't go on forever in either direction. It has 2 endpoints and has a set fixed length. If you know the coordinates of each endpoint, you can use the distance formula to find that length.

Using the hypergeometric distribution, it is found that the probabilities are given as follows:
a) 0.2059 = 20.59%.
b) 0.5294 = 52.94%.
c) 0.2647 = 26.47%.
What is the hypergeometric distribution formula?
The formula is:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.N is the size of the population.n is the size of the sample.k is the total number of desired outcomes.In this problem, the parameters are as follows: N = 17, k = 8, n = 2.
Item a:
This probbility is P(X = 2), hence:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 2) = h(2,17,2,2) = \frac{C_{8,2}C_{9,0}}{C_{17,2}} = 0.2059[/tex]
Item b:
This probbility is P(X = 1), hence:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 1) = h(1,17,2,2) = \frac{C_{8,1}C_{9,1}}{C_{17,2}} = 0.5294[/tex]
Item c:
This probbility is P(X = 0), hence:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 0) = h(0,17,2,2) = \frac{C_{8,0}C_{9,2}}{C_{17,2}} = 0.2647[/tex]

Step-by-step explanation:
Multiply
3×6 = 18
22-18+52
Add and subtract
22-18 = 4
4+52 = 46
Answer:

Step-by-step explanation:
To solve we must use the order of operations which is PEMDAS.
P-Parenthesis
E-Exponents
M-Multiplication
D-Division
A-Addition
and S-Subtraction
First we multiply -3 and 6 which gives us -18. So our equation is now 22-18+52.
Next we do addition. -18+52 is 34, plus 22 gives us 56.

The revenue, in thousands of dollars, of a new flavor of liquor is given below as function of the number of gallons (in hundreds), x, sold:
[tex]r(x) = 50x - {x}^{2} [/tex]
What is the maximum revenue? Use units
Answer:
$625,000
Step-by-step explanation:
The maximum revenue will be found where the derivative of the revenue function is zero.
r'(x) = 50 -2x = 0
50 = 2x
x = 25
When 2500 gallons are sold, the revenue is ...
r(25) = 50(25) -25(25) = (50 -25)(25) = 25(25) = 625 . . . thousands
The maximum revenue is $625,000.

The thickness of photoresist applied towafers in a semiconductor manufacturing at a particular location onthe wafer is uniformly distributed between 0.2050 and 0.2150micrometers.(a) Determine the cumulative distributionfunction of photoresist thickness.(b) Determine the proportion of wafers that exceeds0.2125 micrometers in photoresist thickness.(c) What thickness is exceeded by 10% of thewafers?(d) Determine the mean and variance of photoresistthickness.
Answer:
a
[tex]f(x)= 100 [x - 0.2050][/tex]
b
[tex]P(X > 0.2125) = 0.25 [/tex]
c
[tex]a = 0.2140[/tex]
d
Mean [tex]\mu = 0.21[/tex]
Variance [tex]\sigma ^2 = 0.0000083 [/tex]
Step-by-step explanation:
From the question we are told that
The thickness of photoresist follows a uniform distribution
So
[tex]X\ \~{}\ U \{ 0.2050 , 0.2150 \}[/tex]
Generally the probability density function is mathematically represented as
[tex]F(x) = \left \{ \frac{1}{ 0.2150 - 02050} , 0.2150< x < 0.2150[/tex]
=> [tex]F(x) = \left \{ 100 , 0.2150< x < 0.2150[/tex]
Generally the cumulative distribution function is
[tex]f(x) = \int\limits^{x}_{- \infty} {F(x)} \, dx[/tex]
Here [tex]- \infty[/tex] means the lower limit which in this case is 02050
So
[tex]f(x) = \int\limits^{x}_{0.2050} {100} \, dx[/tex]
[tex]f(x) = 100 \int\limits^{x}_{0.2050} {1} \, dx[/tex]
=> [tex] f(x)=100 [ x ] | \left \ x} \atop {0.2050}} \right.[/tex]
=> [tex]f(x)= 100 [x - 0.2050][/tex]
Generally the proportion of wafers that exceeds 0.2125 is mathematically represented as
[tex]P(X > 0.2125) = 1 - F(0.2125)[/tex]
=> [tex]P(X > 0.2125) = 1- 100[0.2125 - 0.2050][/tex]
=> [tex]P(X > 0.2125) = 0.25 [/tex]
Generally the thickness which is exceeded by 10% of the wafers is mathematically represented as
[tex]P(X > a ) = 0.10[/tex]
=> [tex]1 - F(a) = 0.10[/tex]
=> [tex]1 -100 (a - 0.2050) = 0.10[/tex]
=> [tex]100(a -0.2050) = 0.90[/tex]
=> [tex]a - 0.2050 = 0.009[/tex]
=> [tex]a = 0.2140[/tex]
Generally the mean is mathematically represented as
[tex]\mu = \frac{ 0.2050 -0.2150 }{2}[/tex]
=> [tex]\mu = 0.21[/tex]
Generally the variance is mathematically represented as
[tex]\sigma ^2 = \frac{1}{12} [0.2150 - 0.2050]^2[/tex]
=> [tex]\sigma ^2 = 0.0000083 [/tex]

A chocolatier makes chocolate bon-bons in the shape of a sphere with a radius of 2cm. The chocolate used in the bon-bons has a density of 1.31 g/cm^3. If the chocolate
used costs $0.06 per gram, how much would the chocolate for 140 bon-bons cost, to
the nearest cent?
We will get the mass of each chocolate sphere, and the cost of 140 of these is $368.56
How much would it cost?
A sphere of radius R has a volume:
V = (4/3)*3.14*R^3
The mass of a sphere of chocolate will be given by the volume times the density, then one ball of chocolate has a mass:
M = (4/3)*3.14*(2cm)^3*(1.31 g/cm^3) = 43.88 g
And we know that the cost is of $0.06 per gram, the cost for 140 of these spheres is:
cost = 140*(44.88 g)*$0.06 = $368.56
