Part (a)

4/15 is the probability of getting a rotten orange

After one is taken and not put back, there are

meaning 3/14 is the probability of a second rotten orange.

Two rotten in a row has the probability (4/15)*(3/14) = 2/35. I skipped a few steps so let me know if you need to see in more detail how I got to that result.

=====================================================

Part (b)

We want to calculate the probability exactly one of the two oranges selected is rotten.

There are two possible cases here:

Let's determine the probability for case 1.

4/15 was mentioned earlier in part (a) as the probability of a rotten orange. There are 15-4 = 11 non-rotten oranges and 15-1 = 14 remaining since we aren't replacing the first selection. That gives 11/14 as the probability the 2nd selection is fresh.

We get (4/15)*(11/14) = 22/105 as the probability for case 1 to happen.

Through similar calculations, the probability for case 2 is (11/15)*(4/14) = 22/105

Cases 1 and 2 are mutually exclusive. Both cannot happen simultaneously. There is no overlap. This fact allows us to add the results to get:

22/105 + 22/105 = 44/105

That fraction cannot be reduced.

The probability that at least one component does not function properly when 2 components are randomly selected from 8 is 1/4, or 0.25.

The total number of ways to select 2 components from 8 is:

C(8,2) = 8! / (2! (8-2)!) = 28

Now, let's find the probability that at least one component does not function properly. We can find this probability by subtracting the probability that both components function properly from 1.

The probability that the first component functions properly is 7/8, since there are 7 working components out of 8. The probability that the second component also functions properly, given that the first component does, is 6/7, since there are 6 working components left out of 7. Therefore, the probability that both components function properly is:

(7/8) * (6/7) = 6/8 = 3/4

So the probability that at least one component does not function properly is:

1 - 3/4 = 1/4

For all n that is higher than or equal to 4, this statement is true.

By taking the cubes of both sides of the inequality, we can demonstrate this.

log2(n3) = [tex]3\sqrt{n}[/tex]

n^(3/2) <= 3 * log2(n) (n)

Since log2(n) > 2 for n >= 4, we can write:

3 * 2 * (log2(n)) = 3 * n where n(3/2) = 3 * log2(n)

This suggests that:

[tex]\sqrt{n} =( \frac{3}{n{log 2}} + n) (n)[/tex]

We come to the conclusion that the square root of n will eventually be less than or equal to log2(n3) for all n higher than or equal to 4 since the right-hand side of this inequality approaches zero as n goes to infinity. The assertion is accurate as a result.

The work required to stretch the spring from its natural length to a distance of 9 inches beyond its natural length is 2.25 lb-ft.

The problem involves calculating the work required to stretch a spring from its natural length to a distance of 9 inches beyond its natural length, given that a force of 192 lb is required to hold the spring stretched 3 ft beyond its natural length.

To solve the problem, we use the formula for the work done by a force that varies with distance, which is given by:

W = (1/2) k (x2^2 - x1^2)

where W is the work done, k is the spring constant, x1 is the initial distance, and x2 is the final distance.

In this case, the initial distance is the natural length of the spring, which is 0 ft, and the final distance is 9/12 ft. To find the spring constant, we use the fact that a force of 192 lb is required to hold the spring stretched 3 ft beyond its natural length, which gives us:

192 = k * 3

Solving for k, we get k = 64 lb/ft.

Substituting the values into the formula, we get:

W = (1/2) * 64 * (9/12)^2

Simplifying, we get:

W = 2.25 lb-ft

This calculation shows how the work done by a force that varies with distance can be calculated using the spring constant and the distances involved.

To solve the equation cos²x + sin x = 1, we can use the trigonometric identity cos²x = 1 - sin²x. By substituting this identity into the equation, we get:

1 - sin²x + sin x = 1

Combining like terms, we get:

1 - sin²x = 0

Solving for sin x, we get:

sin x = 1

However, the sine function has a range of [-1, 1], so the only solution in the interval [0, 2π] is sin x = 1, which corresponds to x = π/2. So the solution to the equation cos²x + sin x = 1 in the interval [0, 2π] is x = π/2.

Answer:

The aeroplane will fly 2000 km if travelling at the same average speed.

Step-by-step explanation:

To calculate the distance an aeroplane will fly in 2 h 30 min if it flies 1400 km in 1 h 45 mins, use the Speed Distance Time formula.

[tex]\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]

There are 60 minutes in one hour.  Therefore:

To calculate the speed of the aeroplane, divide the distance by the time it takes to travel that distance.  Therefore, if an aeroplane flies 1400 km in 1.75 hours then its average speed is:

[tex]\sf Speed=\dfrac{1400\;km}{1.75\;h}=800\;km/h[/tex]

To determine the distance the aeroplane will travel in 2.5 hours, multiply the found speed of 800 km/h by the time:

[tex]\sf Distance=800\;km/h \times 2.5\;h=2000\;km[/tex]

Therefore, the aeroplane will fly 2000 km in 2 h 30 min if travelling at the same average speed.

Answer:

(36/5)

Step-by-step explanation:

y=x^2+36/5

Since x is squared, the result will always be a positive number, regardless of the actual value of x.  Starting with a value of x of zero, the x^2 term will only grow as one moves away from 0.  E.g., (-1)^2 = 1, (-2)^2 = 4, etc.

So the minium for this equation will occur when x = 0.  It only gets larger from that point.  The minimum is (36/5).

In a cyclic quadrilateral, the sum of a pair of opposite angles is 180° (supplementary). The sum of angles in a cyclic quadrilateral is 360 degrees.

Therefore, let's find the angle m∠B in the cyclic quadrilateral.

m∠D = 59 degrees

m∠A = 33 degrees

Therefore,

m∠B = 180 - m∠D

This is because the angle m∠B is opposite to the angle m∠D.
