The greatest possible length of time will be "1020 min".

Given:

The average length of time,

= 960

For all 3 computers,

The minimum length of time,

= 930

Let,

Now,

→     \(\frac{930+930+930+x}{3} = 960\)

→  \(\frac{930+930+930}{3} +\frac{x}{3} =960\)

→           \(\frac{3\times 930}{3} +\frac{x}{3} =960\)

→              \(930+\frac{x}{3}=960\)

→                        \(\frac{x}{3} = 960-930\)

→                        \(x = 30\times 3\)

→                        \(x = 90\)

hence,

The greatest possible length of time will be:

=  \(930+x\)

=  \(930+90\)

=  \(1020 \ min\)

Thus the above is the appropriate answer.

Answer:

x=2

y=5

Step-by-step explanation:

y= x+3...(1)

y= -x+7...(2)

(1) + (2):

y+y= (x+3) + (-x+7)

2y= (x-x) + (3+7)

2y= 10

y= 5

By substituting y=5 into (1),

we have

5= x+3

x+3=5

x= 5-3

x= 2

1) The amplitude c+ is c+l

2) The expectation value is 0

3) The uncertainty ΔSX is √(3/7) c+.

Now, we know that any wave function can be written as a linear combination of two spin states (up and down), which can be written as:

Ψ = c+ |+> + c- |->

where c+ and c- are complex constants, and |+> and |-> are the two orthogonal spin states such that Sx|+> = +1/2|+> and Sx|-> = -1/2|->.

Hence, we can write the given wave function as:Ψ = c+|+> + i/√7|->

Now, we know that the given wave function has been defined in Sx basis, and not in the basis of |+> and |->.

Therefore, we need to write |+> and |-> in terms of |l> and |r> (where |l> and |r> are two orthogonal spin states such that Sy|l> = i/2|l> and Sy|r> = -i/2|r>).

Now, |+> can be written as:|+> = 1/√2(|l> + |r>)

Similarly, |-> can be written as:|-> = 1/√2(|l> - |r>)

Therefore, the given wave function can be written as:Ψ = (c+/√2)(|l> + |r>) + i/(√7√2)(|l> - |r>)

Therefore, we can write:c+|l> + i/(√7)|r> = (c+/√2)|+> + i/(√7√2)|->

Comparing the coefficients of |+> and |-> on both sides of the above equation, we get:

c+/√2 = c+l/√2 + i/(√7√2)

Therefore, c+ = c+l

The amplitude c+ is a real number and is equal to c+l

The expectation value of the operator Sx is given by: = <Ψ|Sx|Ψ>

Now, Sx|l> = 1/2|r> and Sx|r> = -1/2|l>

Hence, = (c+l*) + (c+l) + (i/√7) - (i/√7)(c+l*)= -i/√7(c+l*) + i/√7(c+l)= 2i/√7 Im(c+)

As c+ is a real number, Im(c+) = 0

Therefore, = 0

The uncertainty ΔSX in the state |Ψ> is given by:

ΔSX = √( - 2)

where = <Ψ|Sx2|Ψ>and2 = (<Ψ|Sx|Ψ>)2

Now, Sx2|l> = 1/4|l> and Sx2|r> = 1/4|r>

Hence, = (c+l*) + (c+l) + (i/√7) - (i/√7)(c+l*)= 1/4(c+l* + c+l) + 1/4(c+l + c+l*) + i/(2√7)(c+l* - c+l) - i/(2√7)(c+l - c+l*)= = 1/4(c+l + c+l*)

Now,2 = (2i/√7)2= 4/7ΔSX = √( - 2)= √(1/4(c+l + c+l*) - 4/7)= √(3/14(c+l + c+l*))= √(3/14 * 2c+)= √(3/7) c+

The opposite of multiplication is division. The opposite of division is multiplication. The opposite of taking a square root is squaring

Step-by-step explanation:

The the coordinates of the other endpoint of a line segment with an endpoint of (-1,8) and a midpoint of (5, 2) is ( 11,-4 ).

A midpoint is simply a point that divides a line segment into two equal halves.

The midpoint formula is expressed as;

M = ( (x₁+x₂)/2, (y₁+y₂)/2

Given the data in the question;

Midpoint (5,2)

Endpoint 1 ( -1,8)

Endpoint 2 ( x₂,y₂)

To determine the coordinate of endpoint 2, plug the given points into the midpoint formula above and solve for x₂ and y₂.

First, we get the x-coordinate.

x = (x₁+x₂)/2

5 = ( -1 + x₂ )/2

( -1 + x₂ ) = 5 × 2

( -1 + x₂ ) = 10

x₂ = 10 + 1

x₂ = 11

Next, we get the y-coordinate

2 = ( 8 +y₂ )/2

8 +y₂ = 2 × 2

8 + y₂ = 4

y₂ = 4 - 8

y₂ = -4

Therefore, the coordinates of the other endpoint is ( 11,-4).

Answer:

y=-5x/3+26/3

Step-by-step explanation:

Because we want the equation to look like y=mx+b, rearrange the terms.

Since 26-5x is the same as -5x+26, rewrite it like that.

3y=-5x+26

Now, since we want the value of y, divide by 3 on both sides.

3y/3=y

-5x/3= -5x/3

26/3= 26/3

The simplest form would look like:

Step-by-step explanation:

The largest possible area for the rectangle is (64/9)√6, which corresponds to option (a).

To find the largest possible area for a rectangle with its base on the x-axis and upper vertices on the curve y = 8 - x^2, we will follow these steps:

1. Write down the area function: The area A of the rectangle can be expressed as A = x(8 - x^2) = 8x - x^3.
2. Find the critical points: To maximize the area, we need to find the critical points of the area function. To do this, we take the first derivative of A with respect to x and set it equal to 0.
  dA/dx = 8 - 3x^2 = 0
3. Solve for x: To find the critical points, we solve the equation from Step 2 for x:
  3x^2 = 8
  x^2 = 8/3
  x = ±√(8/3)
4. Determine which critical point maximizes the area: Since the area cannot be negative, only the positive value of x is relevant. Therefore, x = √(8/3).
5. Find the corresponding y-value: Now we plug the x-value back into the curve equation y = 8 - x^2 to find the y-value of the upper vertices:
  y = 8 - (√(8/3))^2 = 8 - 8/3 = 16/3
6. Calculate the maximum area: Finally, we multiply the base (x-value) by the height (y-value) to find the largest possible area for the rectangle:
  A_max = x * y = (√(8/3)) * (16/3) = (64/9)√6

So, the largest possible area for the rectangle is (64/9)√6, which corresponds to option (a).

The maximum likelihood estimate of t is at the endpoint t = 0.

We have,
To find the maximum likelihood estimates of t, follow these steps:

1. Write down the likelihood function L(t) for the given pdf f(t).

The likelihood function is the same as the pdf, which is:
L(t) = (1 - t)^k

2. Take the natural logarithm of the likelihood function, ln(L(t)), to make it easier to work with:
ln(L(t)) = ln((1 - t)^k)

3. Use the properties of logarithms to simplify the expression:
ln(L(t)) = k x ln(1 - t)

4. Differentiate ln(L(t)) with respect to t to find the critical points that might correspond to the maximum likelihood estimate:
d(ln(L(t))) / dt = - k / (1 - t)

5. Set the derivative equal to zero and solve for t:
- k / (1 - t) = 0
Since k is nonzero, this equation implies that there is no solution for t in the interval [0, 1].

Thus, the maximum likelihood estimate of t does not occur at a critical point in the interval.

6. Since there are no critical points, we must check the endpoints of the interval, t = 0 and t = 1, to find the maximum likelihood estimate.

The likelihood function L(t) = (1 - t)^k has its maximum value at the endpoint where the derivative is positive.

In this case,

The derivative -k / (1-t) is positive when t = 0.

Thus, the maximum likelihood estimate of t is at the endpoint t = 0.

Thus,

The maximum likelihood estimate of t is at the endpoint t = 0.

a) The probability that no defective component will be chosen when selecting 5 components at random is approximately 0.7738, or 77.38%.

b) The probability that exactly 2 out of the 5 components will be defective is approximately 0.0874, or 8.74%.

a) To calculate the probability that no defective component will be chosen when selecting 5 components at random, we need to determine the probability of selecting a non-defective component for each selection.

Since 5% of the components are faulty, the probability of selecting a non-defective component in each selection is 1 - 0.05 = 0.95.

The probability of selecting no defective components can be calculated using the multiplication rule for independent events. We multiply the probabilities of each selection being non-defective:

Probability of selecting no defective components = (0.95)⁵

Probability of selecting no defective components = 0.7738

b) To calculate the probability that exactly 2 out of the 5 components will be defective, we need to consider the different combinations of selecting 2 defective components out of 5.

The probability of selecting exactly 2 defective components can be calculated using the binomial probability formula:

Probability = (Number of ways to choose 2 defective components) * (Probability of selecting a defective component)^(Number of defective components) * (Probability of selecting a non-defective component)^(Number of non-defective components)

Probability = (5 choose 2) * (0.05)² * (0.95)³

Probability = (5! / (2! * (5-2)!)) * (0.05)² * (0.95)³

Probability = 0.0874

Step-by-step explanation:

The maximum profit is 6 and it is obtained when we mix 0.6 kg of type A, 0 kg of type B, and 0.4 kg of type C.

The optimal mix for the maximum profit can be found as follows:

The company mixes three types of toffees, A, B, and C. Let the weights of type A, B, and C be a, b, and c kg, respectively. Let us assume that we are making 1kg of toffee pack. Therefore, the weight of type C should be 1 - (a + b) kg. Also, the mixture must contain at least 300 gms of type A i.e a >= 0.3 kg

Also, the weight of the first two types (A and B) must be at least equal to the weight of type C, i.e a + b >= c. This condition can also be written as a + b - c >= 0

Let us now calculate the total cost of making 1kg of toffee pack.

Cost = 20a + 10b + 5c

If the pack is sold at Rs. 17, then the profit per 1kg of toffee pack is by

Profit = Selling Price - Cost = 17 - (20a + 10b + 5c)

Now we have the following linear programming problem:

Maximize P = 17 - (20a + 10b + 5c)

Subject to constraints: a + b + c = 1 (since we are making 1kg of toffee pack)

a >= 0.3a + b - c >= 0a, b, c >= 0

We can use the simplex method to solve this linear programming problem. However, to save time, we can solve it graphically. The feasible region is as follows:

We can see that the corner points of the feasible region are: (0.3, 0, 0.7), (0.6, 0, 0.4), (0, 0.5, 0.5), and (0, 1, 0).

Let us calculate the profit at each of these corner points. For example, at the point (0.3, 0, 0.7), we have a = 0.3, b = 0, and c = 0.7. Therefore, the profit is

P = 17 - (20(0.3) + 10(0) + 5(0.7)) = 3.5

Similarly, we can calculate the profit at the other corner points as well. The corner point (0.3, 0, 0.7) gives a profit of 3.5

Corner point (0.6, 0, 0.4) result in a profit of 6

Corner point (0, 0.5, 0.5) results in a profit of 5

Corner point (0, 1, 0) gives a profit of 3

Explanation:

Parallel lines have equal slopes, but different y intercepts. If the original line has slope of 2, then anything parallel to this will also have slope of 2. The same applies for 1/2 as well.

Perpendicular slopes multiply to -1, assuming neither line is horizontal nor vertical. If the original slope is 2, then its perpendicular counterpart is -1/2. We can apply the negative reciprocal to 2 and that leads to -1/2.

If the original slope is 1/2, then we flip the fraction to 2/1 aka 2. Then flip the sign to -2. Therefore, 1/2 and -2 are perpendicular slopes.
