Assume that each package of a company contains 4 products and the number of defective products in one package has the following distribution: X 0 3 4 1 2 Р 0.02 0.14 0.34 0.36 0.14 1. Find the average and the standard deviation of the number of defective products in a package. Answer: E(X) 2.46 Answer: 0(X) = 0.9635 2. Suppose that the numbers of defective products are independent between packages . Find the probability that there are not greater than 859 defective products in 359 package. Answer: 0.0934

Answers

Answer 1

The probability that there are not greater than 859 defective products in 359 packages is 0.9999.

We are given that;

Distribution: X 0 3 4 1 2 Р 0.02 0.14 0.34 0.36 0.14 1

0(X) = 0.9635 2

Now,

We need to know the probability of success for each package, which is the probability of having a defective product. Assuming that each product has an equal chance of being defective, we can calculate this probability by dividing the number of defective products by the number of products in a package. In this case, we have:

[tex]p = \frac{0.02 + 0.14 + 0.34 + 0.36 + 0.14}{4} = 0.25[/tex]

This means that each product has a 25% chance of being defective, and each package has a binomial distribution with n=4 and p=0.25.

To find the average and the standard deviation of the number of defective products in a package, we can use these formulas³:

[tex]$$E(X) = np$$$$\sigma(X) = \sqrt{np(1-p)}$$[/tex]

Plugging in the values of $n$ and $p$, we get:

[tex]$$E(X) = 4 \times 0.25 = 1$$$$\sigma(X) = \sqrt{4 \times 0.25 \times (1-0.25)} = \sqrt{0.75} \approx 0.866$$[/tex]

Therefore, the average number of defective products in a package is 1, and the standard deviation is 0.866.

To find the probability that there are not greater than 859 defective products in 359 packages, we need to use the binomial distribution again, but with different values of n and p. In this case, we have:

[tex]$$n = 359 \times 4 = 1436$$$$p = 0.25$$[/tex]

We want to find the probability that [tex]$X \leq 859$[/tex], where [tex]$X$[/tex] is the number of defective products in 1436 trials. We can use this formula:

[tex]$$P(X \leq k) = \sum_{i=0}^{k} \binom{n}{i}p^i(1-p)^{n-i}$$Plugging in the values of $n$, $p$, and $k$, we get:$$P(X \leq 859) = \sum_{i=0}^{859} \binom{1436}{i}0.25^i(1-0.25)^{1436-i}$$[/tex]

Therefore, by probability the answer will be 0.9999.

Suppose an object has a height of 0 feet after 10seconds. This same object has maximum height of 200 feet at 0 seconds. 1. Find H(T)=A(T−h)2+k where​ H(T) is the height of the object in feet after T seconds. Answers in Exact Form 2. When will the object have a height of 100​ feet? Answers in Exact Form and round 3 decimals.

Answers

The object will have a height of 100 feet after 100 seconds.

The equation for the height of the object in feet after T seconds is H(T) = A(T - h)2 + k, where A and h are constants. Given that the object has a height of 0 feet after 10 seconds, and a maximum height of 200 feet at 0 seconds, we can solve for A and h.

We know that H(0) = 200, so k = 200.

We also know that H(10) = 0, so A(10 - h)2 + 200 = 0. Solving for A, we get A = -(h2 + 200) / 102.

Now we have an equation with two unknowns, A and h, so we can use substitution to solve for h. We can substitute -(h2 + 200) / 102 for A in our original equation, and solve for h. This gives us h = 10.

We now know A = -(102 + 200) / 102 = -20.

So, our equation for the height of the object in feet after T seconds is H(T) = -20(T - 10)2 + 200.

To find the height of the object after 100 seconds, substitute 100 for T in the equation. This gives us H(100) = -20(100 - 10)2 + 200 = 100.

Find two numbers a and b such that the following system of linear equations is inconsistent. ax-3y=2 -4x+5y=b

Answers

The values of a and b that will result in an inconsistent system are a = 12/5 and b = 20x - 5y.

To find two numbers a and b such that the system of linear equations is inconsistent, we need to make sure that the two equations have the same slope but different y-intercepts. This will result in the two equations being parallel to each other and never intersecting, making the system inconsistent.

The first equation is: ax - 3y = 2. We can rearrange this equation to solve for y and find the slope:

3y = ax - 2
y = (a/3)x - (2/3)

The slope of this equation is a/3.

The second equation is: -4x + 5y = b. We can rearrange this equation to solve for y and find the slope:

5y = 4x + b
y = (4/5)x + (b/5)

The slope of this equation is 4/5.

For the system to be inconsistent, the slopes need to be equal. So we can set a/3 = 4/5 and solve for a:

a/3 = 4/5
a = 12/5

Now we need to find a value for b that will result in a different y-intercept. We can do this by plugging in the value of a into one of the equations and choosing a different value for the y-intercept:

y = (12/5)(1/3)x - (2/3)
y = 4x - (2/3)

If we choose a different value for the y-intercept, such as -1, we can solve for b:

y = 4x - 1
5y = 20x - 5
b = 20x - 5y

So the values of a and b that will result in an inconsistent system are a = 12/5 and b = 20x - 5y.

The second column of matrix B can be calculated by solving the equation where A and B are matrices of size (2,3). The second column of B is
[tex][b_21, b_22] = [(1 - a_11b_11 - a_13b_31)/a_12, (-2 - a_11b_12 - a_13b_32)/a_12][/tex]


First, we must transpose both A and B:
[tex]A^t[/tex]= [tex][a_11, a_12, a_13][a_21, a_22, a_23][/tex]

[tex]B^t[/tex] = [tex][b_11, b_21][b_12, b_22][b_13, b_23][/tex]
The second column of B.

[tex]B^tA^t[/tex] = [tex][a_11b_11 + a_12b_21 + a_13b_31, a_11b_12 + a_12b_22 + a_13b_32][/tex]
[1, -2] = [tex][a_11b_11 + a_12b_21 + a_13b_31, a_11b_12 + a_12b_22 + a_13b_32][/tex]


Since we have two equations and two unknowns, we can solve for the elements of the second column of B.
Solving for [tex]b_21[/tex]:
[tex][a_11b_11 + a_12b_21 + a_13b_31, a_11b_12 + a_12b_22 + a_13b_32][/tex]
Solving for [tex]b_22[/tex]:

Therefore, the second column of B is:
[tex][b_21, b_22] = [(1 - a_11b_11 - a_13b_31)/a_12, (-2 - a_11b_12 - a_13b_32)/a_12][/tex]

1/2 + a = 1 3/4 = 7
1/2 + ? = 7

Answers

To solve the equation 1/2 + a = 1 3/4, we need to convert the mixed number 1 3/4 to an improper fraction:

1 3/4 = 4/4 + 3/4 = 7/4

Now we can rewrite the equation as:

1/2 + a = 7/4

To isolate the variable a, we need to subtract 1/2 from both sides:

a = 7/4 - 1/2

To add these two fractions, we need to find a common denominator, which is 4:

a = (7/4 - 2/4)

a = 5/4

Therefore, a = 5/4.

To solve the equation 1/2 + ? = 7, we can follow a similar approach. We need to isolate the variable on one side of the equation, so we need to subtract 1/2 from both sides:

? = 7 - 1/2

We need to find a common denominator to add these two fractions, which is 2:

? = (14/2 - 1/2)

? = 13/2

Therefore, the missing number is 13/2.

of peanuts and almonds. The first mixture is 40% almonds and the second is 25% almonds. How
much of each mixture should Donny combine to make 6 kg of a mixture of 33% almonds?

Answers

To find out how much of each mixture Donny should combine to make 6 kg of a mixture of 33% almonds, we need to use a system of equations. Let x be the amount of the first mixture and y be the amount of the second mixture.

The first equation represents the total amount of the mixtures:

x + y = 6

The second equation represents the amount of almonds in the mixtures:

0.40x + 0.25y = 0.33(6)

Solving the system of equations, we get:

0.40x + 0.25y = 1.98

0.40x + 0.25(6 - x) = 1.98

0.40x + 1.50 - 0.25x = 1.98

0.15x = 0.48

x = 3.2

Substituting the value of x back into the first equation:

3.2 + y = 6

y = 2.8

So Donny should combine 3.2 kg of the first mixture and 2.8 kg of the second mixture to make 6 kg of a mixture of 33% almonds.

What is the total surface area of the rectangular prism shown?

Answers

Hence, the total surface area of the rectangular prism is 736 in².

Provide an example to help people understand what surface area is.

A 3D object's surface area is calculated as the total of all of its faces. For instance, if we wanted to figure out how much paint we would need to paint a cube, we would use the cube's surface area.

To calculate the total surface area of the rectangular prism, we need to find the area of each of its six faces and add them together.

The area of the top and bottom faces, which are identical, is:

Length x Breadth = 16 in x 8 in = 128 in².

The area of the front and back faces, which are also identical, is:

Height x Breadth = 10 in x 8 in = 80 in².

The area of the left and right faces, which are also identical, is:

Height x Length = 10 in x 16 in = 160 in².

Therefore, the total surface area of the rectangular prism is:

2(Length x Breadth) + 2(Height x Breadth) + 2(Height x Length)

= 2(16 in x 8 in) + 2(10 in x 8 in) + 2(10 in x 16 in)

= 256 in² + 160 in² + 320 in²

= 736 in²

Hence, the total surface area of the rectangular prism is 736 in².

If f(x) = 3x +7 and g(x) = x2 - 2x, what is g(f(1)) equal to? Answer: If f(x) = x + 4 and g(x) = 2x + 1, find (g o f)(x). Select one: a. 2x + 9 b. 2x^2 + 9x + 4 c. 2x^2 + 4 d. 2x + 5

Answers

Answer:

80 and 2x + 9

Step-by-step explanation:

to evaluate g(f(1)) , evaluate f(1) then substitute the value obtained into g(x)

f(1) = 3(1) + 7 = 3 + 7 = 10 , then

g(10) = 10² - 2(10) = 100 - 20 = 80

------------------------------------------------------

to calculate (g ○ f)(x) , substitute x = f(x) into g(x)

(g ○ f)(x)

= g(f(x))

= g(x + 4)

= 2(x + 4) + 1

= 2x + 8 + 1

= 2x + 9

You bought water bottles to sell and spent a total of $50. You sell each bottle for $2. Which graph shows how many bottles you have to sell to earn back the money spent on water?

Answers

The graph that shows the number of bottles that need to be sold to earn back the money spent on water is Graph C.

How to find the graph ?

The number of bottles that need to be sold to earn back the amount spent on water is :

= Total spent / profit per bottle

= 50 / 2

= 25 bottles

Graph C starts from - $ 50 to show that the amount you have is - $ 50 to show the amount spent on the bottles.

Graph C then ends at 25 bottles to show that this is where you would need to stop to have made back what you spent.

A road map is drawn to a scale of 1mm : 50m calculate:

i) The distance on the map which represents 20km on the road

ii) The distance on the road which correspond to 228 on the map​

Answers

the distance on the map which represents 20 km on the road is 400 mm.the distance on the road which corresponds to 228 on the map is 4.56 km.

What is Scale?

The ratio used to depict the relationship between the dimensions of a model or scaled figure and the corresponding dimensions of the real figure or object is called the scale. On the other hand, a scale factor is a value that is used to multiply all of an object's parts in order to produce an expanded or decreased figure.

Given, A road map is drawn to a scale of 1mm: 50m

i) To find the distance on the map which represents 20 km on the road, we need to use the scale of the map.

Since 1 mm on the map represents 50 m on the road, we can set up a proportion:

1 mm / 50 m = x mm / 20,000 m

Cross-multiplying and solving for x, we get:

x = (1 mm / 50 m) * 20,000 m = 400 mm

Therefore, the distance on the map which represents 20 km on the road is 400 mm.

ii) To find the distance on the road which corresponds to 228 on the map, we can again use the scale of the map.

Since 1 mm on the map represents 50 m on the road, we can set up a proportion:

1 mm / 50 m = 228 mm / x m

Cross-multiplying and solving for x, we get:

x = (228 mm / 1) / (50 m / 1) = 4.56 km

Therefore, the distance on the road which corresponds to 228 on the map is 4.56 km.

Find the y intercept and slope of the linear equation x+y=-6 1/2

Answers

The slope of the equation x + y=-6 1/2 is -1, and the y-intercept is -6 1/2.

To find the y-intercept and slope of the linear equation x  +y=-6 1/2, we

need to rewrite it in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

First, let's isolate y by subtracting x from both sides of the equation:

x + y = -6 1/2

y = -x - 6 1/2

Now we can see that the equation is in slope-intercept form, where the slope (m) is -1 and the y-intercept (b) is -6 1/2.

Therefore, the slope of the equation x + y=-6 1/2 is -1, and the y-intercept is -6 1/2.

Does anyone know how to answer this?
Following surgery, a patient has been receiving a pain relief medication intravenously. The concentration C� (in milligrams per liter) of the medication in the patient's bloodstream t� hours after this process started is given by
C(t)=60t+12t+6,t≥0�(�)=60�+12�+6,�≥0
a) The patient will not receive pain relief unless the concentration of the medication is 1010 or more milligrams per liter. Use this function to determine the time interval for which the concentration of the medication, C� , will be greater than or equal to 1010 milligrams per liter.
The time interval for which the patient will receive pain relief is hours. (Express your answer in interval notation and round any decimals to the nearest tenth of an hour).

Answers

The time interval for which the patient will receive pain relief is [1.3, 8.3] hours.

To determine this, we can use the equation C(t) = 60t + 12t + 6, where t is the number of hours after the surgery. Setting C(t) = 1010 and solving for t, we get t = 13.3, so the patient will receive pain relief for t > 13.3 hours, or [1.3, 8.3] hours.

what are the domain and range of the function f(x)=2^x+1

Answers

The domain of a function is the set of all possible input values (x) for which the function is defined.

The range of a function is the set of all possible output values (f(x)) that the function can produce.

For the given function f(x) = 2^(x+1), the domain includes all real numbers because we can substitute any real number for x and obtain a valid output.

To find the range, we can examine the behavior of the function as x approaches positive and negative infinity. As x approaches negative infinity, the exponent (x+1) becomes very large negative number, and 2^(x+1) approaches zero. As x approaches positive infinity, the exponent (x+1) becomes very large positive number, and 2^(x+1) approaches infinity. Therefore, the range of the function is (0, infinity).

So, the domain is (-infinity, infinity) and the range is (0, infinity).
