A manufacturer has determined that for every 1000 units it produces, 3 will be faulty. What is the probability that an order of 50 units will have one or more faulty units
Answer:
0.1393 = 13.93% probability that an order of 50 units will have one or more faulty units.
Step-by-step explanation:
Mean for a number of units, which means that the Poisson distribution is used to solve this question.
Poisson Distribution:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
\(P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}\)
In which
x is the number of sucesses
e = 2.71828 is the Euler number
\(\mu\) is the mean in the given interval.
Mean:
3 defective for 1000, how many for 50?
3 - 1000
\(\mu\) - 50
Applying cross multiplication:
\(\mu = \frac{3*50}{1000} = 0.15\)
What is the probability that an order of 50 units will have one or more faulty units?
This is:
\(P(X \geq 1) = 1 - P(X = 0)\)
In which
\(P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}\)
\(P(X = 0) = \frac{e^{-0.15}*(0.15)^{0}}{(0)!} = 0.8607\)
\(P(X \geq 1) = 1 - P(X = 0) = 1 - 0.8607 = 0.1393\)
0.1393 = 13.93% probability that an order of 50 units will have one or more faulty units.

Step-by-step explanation:
A trapezoid has an area given by A =1-2(b1-b2)h,where b1,is the length of one base, b2 is the length of the other
base, and h is the height. If the trapezoid has an area of 14 square units, solve for b in terms of the other variables.
The value of \(b_{1}\) is 69/4h and value of \(b_{2}\) is 43/4h if the area of trapezoid is 14 square units.
Given that area is equal to 1-2(\(b_{1} -b_{2}\))h and area is 14 square units.
We know that area of trapezoid is equal to (a+b)h/2.
We have to put the given equation equal to 14 to get our first equation.
14=1-2(\(b_{1} -b_{2}\))h
14=1-2\(b_{1}\)h+2\(b_{2}\)h
2\(b_{1}\)h-2\(b_{2}\)h=-13------------1
Now put the value of area in the formula of area of trapezoid.
14=\((b_{1} +b_{2})h/2\)
\(b_{1}\)h+\(b_{2}h\)=28-----------------2
Multiply equation 2 by 2 and then subtract 2 from 1
\(2b_{1}h -2b_{2}h -2b_{1}h-2b_{2}h\)=-13-56
-4\(b_{2}h\)=-43
\(b_{2}\)=43/4h
Put the value of \(b_{2}\) in 2 to get the value of \(b_{1}\).
\(b_{1} h+43/4h*h=28\)
\(b_{1}\)=69/4h
Hence The value of \(b_{1}\) is 69/4h and value of \(b_{2}\) is 51/4h if the area of trapezoid is 14 square units.

C. 3.42 x 10^-10
D. 3.42 x 10^11
E. 3.42 x 10^13
Answer: 3.42x10^11
Step-by-step explanation:
The number 0.0000000000342 is equivalent to 3.42 × 10^-11. Hence, option B is the correct answer.
This type of conversion is called scientific notation.
Firstly we have to place a decimal between the two non-zero numbers which is 3.42.
And then, count the number of decimals that were moved. That is 11.
And then, determine whether the decimal point is to be moved to the left or right to return to the original number. If the decimal is moved right then the exponent is negative. If the decimal is moved left then the exponent is positive.
Here, the exponent is moved right and the decimal will be negative.
In this case, it is written as 3.42 × 10^-11.

P -5, 1 R 4,4..find the slope
Answer:
The slope between (-5,1) and (4,4) is 1/3
Step-by-step explanation:
When you're given 2 points and you must find the slope between those 2 points, you can find the distance between the y values and the x values.
For example in this case, the distance in our first y value is 3. So we know that y is always above x so we have 3/x so far.
Next to find the x values you do the exact same, and we get a distance of 9 from -5 to +4.
Now we have 3/9 which should be simplified to 1/3. When plotting this point, you'll use the strategy Rise over Run or Rise/Run.
(Side Note: Y is always above X so we know the Rise must be Y and the X must be Run.)
Y/X = Rise/Run

calculate the derivative of x^3cosx
Since g(x) is the product of two terms, we can use the Product Rule to find the derivative.
We essentially have
\(g(x)=f(x)\cdot h(x)\)where,
\(\begin{gathered} f(x)=x^3\text{ and} \\ h(x)=cosx \end{gathered}\)Thus, the Product Rule states that the derivative is equal to:
\(f^{\prime}(x)h(x)+f(x)h^{\prime}(x)\)To differentiate f(x), we can use the Power Rule, where the exponent becomes the coefficient, and we decrement the power.
Therefore,
\(f^{\prime}(x)=3x^2\)And from our knowledge of derivatives of trig functions
\(h^{\prime}(x)=-\sin x\)We can now plug these values into the product rule expression to get
\(3x^2(\cos x)+x^3(-\sin x)\)We can rewrite this as
\(3x^2(\cos x)-x^3(\sin x)\)Hence,
\(3x^2\cos x-x^3\sin x\)Therefore, the derivative is
\(3x^2\cos x-x^3\sin x\)Cory has $24 more than twice as much as Stan. Together they have $150. How much money dose each have ?

The quadratic equation y = x² - 8 · x + 18 represents the parabola shown in the figure.
How to derive the quadratic equation behind the graph of the parabola
In this problem we find a representation of a parabola, which is described algebraically by quadratic equations, that is, polynomials of the form:
y = a · x² + b · x + c
Where a, b, c are the coefficients of the polynomial.
We can determine the value of the coefficients from the knowledge of three points set on Cartesian plane. First, select the points from Cartesian plane:
(x₁, y₁) = (0, 18), (x₂, y₂) = (4, 2), (x₃, y₃) = (7, 11)
Second, create a system of linear equations with three variables and three equations by replacing the variables x and y on the quadratic equation:
c = 18
16 · a + 4 · b + c = 2
49 · a + 7 · b + c = 11
Third, solve the system by numerical methods:
(a, b, c) = (1, - 8, 18)
Fourth, write the resulting quadratic equation:
y = x² - 8 · x + 18

A number cube is rolled. Event A is rolling an odd number, and event B is rolling a factor of 12. What is P(AU B)?
Explanation:
A = set of odd numbers = {1,3,5}
B = set of factors of 12 = {1,2,3,4,6}
A U B = union of set A and set B
A U B = {1,3,5} union {1,2,3,4,6}
A U B = {1,3,5, 1,2,3,4,6}
A U B = {1,2,3,4,5,6}
The set union operation combines two sets into one bigger set. Duplicates are tossed out.
There are 6 elements in the set A U B = {1,2,3,4,5,6} out of 6 faces of the number cube.
Therefore, the probability event A U B happens is 6/6 = 1 = 100%; i.e. it is guaranteed to happen. Each face of the number cube is either odd, a factor of 12, or both.
Side notes:
A U B can be read out as "event A or event B"; so P(A U B) is "the probability event A happens or B happens or both".A intersect B = {1,3} = values that are in both set A and set B at the same time. These are both odd and a factor of 12.
