What is the range of the following relation?

Answer: So there is only 1 possible outcome when choosing 8 candidates out of a pool of 8, which is simply selecting all 8 candidates.

Step-by-step explanation: Assuming that the order of the candidates does not matter, the number of possible outcomes can be calculated by finding the number of ways to choose a group of 8 candidates out of a total of 8.

This can be represented by the combination formula:

nCr = n! / (r! * (n-r)!)

where n is the total number of candidates and r is the number of candidates to be chosen.

In this case, we have:

n = 8 (total number of candidates)

r = 8 (number of candidates to be chosen)

Therefore, the number of possible outcomes is:

8C8 = 8! / (8! * (8-8)!) = 1

So there is only 1 possible outcome when choosing 8 candidates out of a pool of 8, which is simply selecting all 8 candidates.

Using it's critical points, it is found that the least possible degree of the polynomial graphed above is 4.

The critical points of a function are the values of x for which:

f'(x) = 0

At these critical points, the behavior of the function changes from increasing to decreasing or vice versa.

If a function has n critical points, the least possible degree is of n + 1.

From the changes in behavior of the graph, the function has critical points at:

x ≈ -3.5

x ≈ -1.5

x ≈ 0.25

The function has 3 critical points, hence the least possible degree of the polynomial graphed above is 4.

Answer: 1 just like my answer dawg

Step-by-step explanation:

Maraging (18% Ni) steel has a better tolerance to defects and fracture toughness compared to Medium strength steel.

The tolerance to defects and fracture toughness of a material can be evaluated using its fracture toughness parameter, Kic. The higher the Kic value, the better the material's tolerance to defects and fracture toughness.

To compare the two materials, we can use the concept of critical stress intensity factor (Kic) and factor of safety (FoS). The critical stress intensity factor is the maximum value of stress intensity factor (K) that a material can withstand without fracturing. The factor of safety is the ratio of the maximum allowable stress to the design stress, and it is used to ensure a safety margin in the design.

Assuming that the two materials have the same defect to tolerance ratio, we can calculate the maximum allowable stress for each material using the following formula:

σmax = FoS * Kic / (π * a)

where σmax is the maximum allowable stress, FoS is the factor of safety (assumed to be 2), Kic is the fracture toughness parameter, and a is the size of the defect.

Let's assume a defect size of 1 mm for both materials. Using the values given in the question, we get:

For Maraging (18% Ni) steel:

σmax = 2 * 82 * 10^6 / (π * 1 * 10^-3) = 52.1 GPa

For Medium strength steel:

σmax = 2 * 50 * 10^6 / (π * 1 * 10^-3) = 31.8 GPa

Therefore, Maraging steel has a higher maximum allowable stress, which indicates that it has a better tolerance to defects compared to medium strength steel.

To compare the fracture toughness of the two materials, we can use their respective Kic values. The higher Kic value indicates a better tolerance to defects and fracture toughness.

Comparing the given values, we can see that Maraging (18% Ni) steel has a higher fracture toughness parameter (Kic= 82 MNm-3/2) compared to Medium strength steel (Kic= 50 MNm-3/2).

Therefore, Maraging (18% Ni) steel has a better tolerance to defects and fracture toughness compared to Medium strength steel.

Answer:

x = 82°

Step-by-step explanation:

From inspection of the given diagram:

The tangent of a circle is always perpendicular to the radius.

Therefore, m∠BAP = m∠BCP = 90°.

Since the sum of the interior angles in a quadrilateral is 360°, then:

⇒ m∠BAP + m∠APC + m∠BCP + m∠ABC = 360°

⇒ 90° + 98° + 90° + x = 360°

⇒ 278° + x = 360°

⇒ 278° + x - 278° = 360° - 278°

⇒ x = 82°

Therefore, the value of x is 82°.

The radius of the circle that has an area of 380 square inches is calculated as: 11 inches.

The radius of a circle is half of the diameter. It connects from the center of the circle to any point on the circumference on the circle.

We are given the following information about a circle:

Area of the circle = 380 square inches

To find the radius of the circle, recall the formula of the area of a circle which is:

area = πr², where r is the radius, π = 3.14

Therefore:

380 = πr²

380 = 3.14 * r²

380/3.14 = r²

r² = 121.01

r = √121.01

Step-by-step explanation:

You want to find the equation for a line that passes through the point (4,21) and has a slope of 01.

First of all, remember what the equation of a line is:

y = mx+b

Where: m is the slope, and b is the y-intercept

To start, you know what m is; it's just the slope, which you said was 01. So you can right away fill in the equation for a line somewhat to read:

y=01x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(4,21). When x of the line is 4, y of the line must be 21.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the 1 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (4,21).

The factorization of 7x^2 -6x is x(7x - 6).

It should be noted that to factorize 7x^2 -6x, we need to find two numbers that can multiply to give 7 times the coefficient of x^2 (which is 7), and add to give the coefficient of x (which is -6).

The first step is to factor out the greatest common factor (GCF) of the two terms, which is x:

7x^2 - 6x = x(7x - 6)

Now we can see that the two numbers we need are 7 and -6, since 7 times -6 is -42 and 7 + (-6) is 1. So we can rewrite the expression as:

7x^2 - 6x = x(7x - 6) = x(7x + (-6)) = x(7x - 6)

Therefore, the factorization of 7x^2 -6x is x(7x - 6).

Answer:

37.5

Step-by-step explanation:

To find the interquartile range (IQR) for a data set, we need to find the difference between the upper quartile (Q3) and the lower quartile (Q1).

To find Q1 and Q3, we first need to order the data set from lowest to highest:

25, 49, 50, 60, 60, 70, 70, 74, 81, 85, 89, 100

There are 12 data points in this set, so the median is the average of the sixth and seventh numbers:

median = (70 + 70)/2 = 70

To find Q1, we take the median of the first half of the data set (the numbers to the left of the median). There are six numbers in the first half, so the median is the average of the third and fourth numbers:

Q1 = (49 + 50)/2 = 49.5

To find Q3, we take the median of the second half of the data set (the numbers to the right of the median). Again, there are six numbers in the second half, so the median is the average of the ninth and tenth numbers:

Q3 = (85 + 89)/2 = 87

Now we can find the IQR by subtracting Q1 from Q3:

IQR = Q3 - Q1 = 87 - 49.5 = 37.5

Therefore, the interquartile range for the given data set is 37.5.

Step-by-step explanation:

the volume of a regular shape is always

ground area × height

9.

so, the ground area is 12 cm².

the whole volume is 288 cm³.

therefore,

288 = 12 × height

height = 288/12 = 24 cm.

10.

we do this almost exactly the same way.

but here we have no regular shape (uniform from the bottom to the top). we have a pyramid.

the volume for a pyramid is

ground area × height / 3.

the ground area is 300 cm².

the volume is 2,050 cm³.

2,050 = 300 × height / 3.

6,150 = 300 × height.

height = 6150/300 = 20.5 cm

The requried shorter base is 4 centimeters and the longer base is 3 times that, or 12 centimeters.

Let's call the shorter base of the trapezoid "b" and the longer base "3b" (since one base is 3 times the length of the other). We know the height is 6 centimeters, and the area is 48 square centimeters. The formula for the area of a trapezoid is:

Area = (b₁ + b₂) * h / 2

where b₁ and b₂ are the lengths of the two parallel bases and h is the height.

Plugging in the values given in the problem, we get:

48 = (b + 3b) * 6 / 2

48 = 2b * 6

4 = b

Therefore, the shorter base is 4 centimeters and the longer base is 3 times that, or 12 centimeters.
