Given that  f'(x)= lim h→0 f(x+h)-f(x) / h √x – 1 for all x,  when x = 5 the value of f'(x) is 1 / (2√5).

To evaluate the expression for f'(x) when x = 5, we need to substitute the value of x into the given limit expression:

f'(5) = lim(h→0) [f(5 + h) - f(5)] / h

Plugging in x = 5 into the given function f(x) = √x - 1, we have:

f(5) = √5 - 1

Now evaluate the limit:

f'(5) = lim(h→0) [√(5 + h) - 1 - (√5 - 1)] / h

f'(5) = lim(h→0) (√(5 + h) - √5) / h

f'(5) = lim(h→0) [(√(5 + h) - √5) / h] * [(√(5 + h) + √5) / (√(5 + h) + √5)]

f'(5) = lim(h→0) [(5 + h - 5) / (h * (√(5 + h) + √5))]

f'(5) = lim(h→0) [h / (h * (√(5 + h) + √5))]

f'(5) = lim(h→0) [1 / (√(5 + h) + √5)]

f'(5) = 1 / (√(5 + 0) + √5)

= 1 / (2√5)

Therefore, when x = 5, the value of f'(x) is 1 / (2√5).

If particular shipment of thousands of components actually has a 7% rate of defects, there is a 54.29% probability that this whole shipment will be accepted.

According to the company's acceptance sampling plan, 25 components are randomly chosen and tested from a shipment before the entire batch is accepted if there are no more than three defects. The probability of choosing a defective component from a sample of 25 is computed as follows, assuming that the shipment genuinely has a 7% defect rate:

P(defective) = 0.07

P(non-defective) = 0.93

Using the binomial distribution, we can calculate the probability of having 0, 1, or 2 defectives in a sample of 25:

P(X ≤ 2) = P(X=0) + P(X=1) + P(X=2)

= (0.93)²⁵ + 25(0.07)(0.93)²⁵ + (0.07)²(0.93)²³

= 0.5429

This means that there is a 54.29% chance of having 2 or fewer defectives in a sample of 25. Since the whole shipment will be accepted if there are fewer than 3 defectives in the sample, this is the probability that the whole shipment will be accepted. Therefore, there is a 54.29% chance that the company will accept the shipment based on their acceptance sampling plan.

Kangaroos are known for their remarkable ability to jump long distances with incredible speed and agility. One of the reasons for this is the unique design of their legs, which have strong muscles and tendons that work together to create powerful jumps.

Each leg of a kangaroo has a tendon connected to a muscle that acts like a spring when the animal jumps.
When a kangaroo jumps, the tendons in its legs stretch and store energy, much like a spring. The more energy stored in the tendons, the more force is generated when the kangaroo pushes off the ground, allowing it to jump higher. As the kangaroo's speed increases, so does the force generated, resulting in even higher jumps.
This is because the tendons in the kangaroo's legs are able to stretch further at higher speeds, allowing them to store more energy. Additionally, the stronger and faster the muscle contractions, the more energy is stored in the tendons, resulting in greater jumping power.
In summary, the tendons in a kangaroo's legs act like springs that store and release energy when the animal jumps. As the kangaroo's speed increases, the tendons are able to stretch further and store more energy, resulting in higher jumps.

To find the y-coordinate of point P on the unit circle, given that its x-coordinate is 5/13, we can utilize the Pythagorean identity for points on the unit circle.

The Pythagorean identity states that for any point (x, y) on the unit circle, the following equation holds true:

x^2 + y^2 = 1

Since we are given the x-coordinate as 5/13, we can substitute this value into the equation and solve for y:

(5/13)^2 + y^2 = 1

25/169 + y^2 = 1

To isolate y^2, we subtract 25/169 from both sides:

y^2 = 1 - 25/169

y^2 = 169/169 - 25/169

y^2 = 144/169

Taking the square root of both sides, we find:

y = ±sqrt(144/169)

Since we are dealing with points on the unit circle, the y-coordinate represents the sine value. Therefore, the y-coordinate of point P is:

y = ±12/13

So, the y-coordinate of point P can be either 12/13 or -12/13.

Step-by-step explanation:

18+(-20)=-2

Answer:

\(\huge\boxed{\text{+}}\)

Step-by-step explanation:

To make this statement true, we want to make it so that when -20 is "something'd" to 18, we get -2.

Let's try all the common operators first - add, subtract, multiply, divide.

Let's try add.

If we put a plus sign there:

\(18 + (-20) = -2\)

Adding a negative is the same as subtracting a positive.

\(18-20=-2\)

This is true! 18 - 20 is indeed -2. This means + is the right operator.

For fun, let me briefly go over what happens with all the other operators.

Subtract:

\(18 - (-20) = -2\\\\18+20=-2\\\\28 \neq -2\)

Multiply:

\(18 \cdot (-20) = -2\\\\-360 \neq -2\)

Divide:

\(18 \div (-20) = -2\\\\-0.9 \neq -2\)

The Law of Cosines to find the angle α between the vectors. (Assume 0° ≤ α ≤ 180°.) v = 3i + j, w = 2i - j. Since 0° ≤ α ≤ 180°, we know that cos(α) cannot be negative. Therefore, there is no solution for α in this case.

To find the angle α between the vectors v and w using the Law of Cosines, we first need to find the magnitude of each vector.

|v| = √(3^2 + 1^2) = √10
|w| = √(2^2 + (-1)^2) = √5

Next, we need to find the dot product of the two vectors:

v · w = (3i + j) · (2i - j) = 6i^2 - j^2 = 6 - 1 = 5

Now we can use the Law of Cosines, which states that:

c^2 = a^2 + b^2 - 2ab cos(C)

Where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

In this case, we can let v be side a, w be side b, and the angle between them (α) be angle C. So we have:

|v - w|^2 = |v|^2 + |w|^2 - 2|v||w| cos(α)

Substituting in the values we found earlier:

|3i + j - (2i - j)|^2 = 10 + 5 - 2√10√5 cos(α)

Simplifying:

|(i + 2j)|^2 = 15 - 2√50 cos(α)
(1 + 4)^2 = 15 - 2√50 cos(α)
25 = 15 - 2√50 cos(α)
2√50 cos(α) = -10
cos(α) = -5/√50 = -1/√10

Since 0° ≤ α ≤ 180°, we know that cos(α) cannot be negative. Therefore, there is no solution for α in this case.

The question requires us to prove that a topological space X is connected if and only if there does not exist a continuous function f: X → Y, where Equip Y = {-1, 1} with the discrete topology.

Firstly, let us understand the definition of connectedness: A topological space X is said to be connected if and only if it cannot be divided into two non-empty open sets.

That is, there do not exist two non-empty disjoint sets U and V, such that U ∪ V = X, U ∩ V = φ, and U and V are both open in X.

Let's suppose that X is a connected space and f: X → Y is a continuous function. Since {−1, 1} is a discrete topology, the preimages of the individual points are open in Y.

Hence, for all points a, b ∈ X, f−1({a}) and f−1({b}) are open sets in X. Now, we have two cases: If f(X) contains both -1 and 1, then we can partition X into f−1({−1}) and f−1({1}).

Since they are preimages of open sets in Y, f−1({−1}) and f−1({1}) are open sets in X. They are also disjoint and non-empty. This contradicts the assumption that X is a connected space. If f(X) contains only -1 or only 1, then f(X) is a closed set in Y. Since f is continuous, X is also a closed set in Y. If X = ∅, then it is trivially connected.

If X ≠ ∅, then X = f−1(f(X)) is disconnected, as X is partitioned into two non-empty disjoint open sets f−1(f(X)) and f−1(Y−f(X)), which are also the preimages of open sets in Y.

This contradicts the assumption that there exists no continuous function from X to Y. Hence, we have proven that a topological space X is connected if and only if there does not exist a continuous function f: X → Y, where Equip Y = {-1, 1} with the discrete topology.

To determine if a data point is considered an outlier for a data set, we need to calculate the interquartile range (IQR) and use it to define the outlier boundaries. The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). The correct option is (B).

We have that Q1 = 9 and Q3 = 17, we can calculate the IQR as follows:

IQR = Q3 - Q1 = 17 - 9 = 8

To identify outliers, we can use the following rule:

- Any data point that is less than Q1 - 1.5 * IQR or greater than Q3 + 1.5 * IQR is considered an outlier.

Using this rule, we can evaluate each data point:

A. 27: This data point is greater than Q3 + 1.5 * IQR = 17 + 1.5 * 8 = 29. It is considered an outlier.

B. 17: This data point is not an outlier because it is equal to the third quartile (Q3).

C. 3: This data point is less than Q1 - 1.5 * IQR = 9 - 1.5 * 8 = -3. It is considered an outlier.

D. 41: This data point is greater than Q3 + 1.5 * IQR = 17 + 1.5 * 8 = 29. It is considered an outlier.

Therefore, the outliers in the data set are A (27) and D (41).

As for when to use the mean, it is generally recommended to use the mean as a measure of central tendency when the data is symmetric and does not have extreme values.

Therefore, the correct option would be B. When the data is symmetric.
