Answer:

7

Step-by-step explanation:

To find the maximum number of turning points of any polynomial function, subtract one from the degree.

Since the degree is 8, subtract 1 from this:

8 - 1

= 7

So, the maximum number of turning points is 7.

The volume would be:

To determine a good ratio for comparing the actual pyramid to a piñata-sized pyramid, we need more information about the dimensions of the actual pyramid and the desired size of the piñata. Once we have that information, we can calculate the ratio by comparing the height, base, and volume of the two pyramids.

Assuming we have the necessary information, let's say the actual pyramid has a height of 10 feet and a base of 8 feet by 8 feet, and we want to create a piñata-sized pyramid with a height of 2 feet and a base of 1 foot by 1 foot. In this case, the ratio would be:

1: (2/10) or 1:5

To calculate the surface area of the piñata pyramid, we can use the formula:

Surface Area = (base x base) + 2(base x slant height)

Using the dimensions given, the surface area would be:

Surface Area = (1 x 1) + 2(1 x sqrt(0.5^2 + 2^2))

Surface Area ≈ 6.83 square feet

To calculate the volume of the piñata pyramid, we can use the formula:

Volume = (1/3)(base x base)(height)

Using the dimensions given, the volume would be:

Volume = (1/3)(1 x 1)(2)

Volume ≈ 0.67 cubic feet

1 + 4 = 5 so we get 1 4 5

then 4+5 = 9, 1 4 5 9

5+9 = 14, 1 4 5 9 14

9+14 = 23, so

1 4 5 9 14 23

23 is the 6th number in this sequence

The sixth number in the Fibonacci sequence with the first two numbers 1 and 4 is 23 and this can be determined by using the arithmetic operations.

Given :

Fibonacci sequence with the first two numbers 1 and 4.

The following steps can be used to determine the sixth number in the Fibonacci sequence:

Given:

Total number of students = 147

Number of students taking math = 95

Number of students taking science = 73

Number of students taking both = 52

To find:

The theoretical probability of randomly choosing a student who is taking math.

Solution:

We have,

Total number of students = 147

Number of students taking math = 95

Now, the theoretical probability of randomly choosing a student who is taking math is

\(P(M)=\dfrac{\text{Number of students taking math}}{\text{Total number of students}}\times 100\)

\(P(M)=\dfrac{95}{147}\times 100\%\)

\(P(M)=64.62585\%\)

\(P(M)\approx 64.6\%\)

The theoretical probability of randomly choosing a student who is taking math is 64.6%.

Therefore, the correct option is C.

{x | x is a natural number with 6 < x < 15}

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

Explanation:

The given set is in roster notation. Think of a baseball or football team (or any sports team) how their roster lists out all of the players. In this case, each number is like a player.

The idea here is to simplify the set so we don't have to write out every single item. Instead we have a rule to make things a bit simpler.

In this case, the set {7, 8, 9, 10, 11, 12, 13, 14} describes all natural numbers from 7 to 14

This means we can say {x | x is a natural number with 6 < x < 15}

Note how the endpoints x = 6 and x = 15 are not included. This is because there isn't a "or equal to" as part of the inequality sign. Sure enough 6 and 15 are not part of the original set.

An equivalent set would be \(\{ x | \text{ x is a natural number with } \ 7 \le x \le 14\}\) and here we have "or equal to" involved. For this example, the endpoints x = 7 and x = 14 are included.

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

Something like choice A and choice D are not complete answers because we don't know if x is a whole number, natural number, rational number, real number, etc. If x was say a real number, then x = 10.75 would be involved with choice A. But 10.75 is not part of the original set.

Answer:

A

Step-by-step explanation:

It can only be a bc its the only one with -4 as b

The absolute value of x minus one is equal to two. Therefore, x must be either one greater than two (x = 3) or one less than two (x = 1).

One less than x results in a value of two in absolute terms. As a result, x minus 1 has an absolute value of 2, which is a positive number. The separation of an integer from zero is its absolute value. As a result, x minus 1 is two units from zero in absolute terms. As x minus one has an absolute value of two, its real value must either be two or a negative two. That is to say, x must either be one more than two (x = 3) or one less than two (x = 1).In order to confirm this, let's look at a few examples. If x = 3, then |x - 1| = |2 - 1| = |1| = 1 which is not equal to two. Therefore, x = 3 is not the answer we are looking for. On the other hand, if x = 1, then |x - 1| = |1 - 1| = |0| = 0 which is not equal to two. Therefore, x = 1 is also not the answer we are looking for. The only two possible solutions for the equation |x - 1| = 2 are x = 3 and x = 1. Therefore, the result of |x - 1| = 2 is that x must be either one greater than two (x = 3) or one less than two (x = 1)

The function \(f(x) = x^2 - c^2\) for x < 6 and f(x) = cx + 45 for x ≥ 6 is continuous on (-∞, ∞) for all values of c except for c = 0.  Consider the definition of continuity.

A function is continuous at a point if the limit of the function as x approaches that point exists and is equal to the value of the function at that point.

For x < 6, the function \(f(x) = x^2 - c^2\) is a polynomial function and is continuous for all values of c since polynomials are continuous everywhere.

For x ≥ 6, the function f(x) = cx + 45 is a linear function. Linear functions are also continuous everywhere, regardless of the value of c.

However, at x = 6, we have a point of discontinuity if c = 0. When c = 0, the function becomes f(x) = 45 for x ≥ 6. In this case, the function has a jump discontinuity at x = 6 since the limit as x approaches 6 from the left is not equal to the value of the function at x = 6.

In conclusion, the function  \(f(x) = x^2 - c^2\) for x < 6 and f(x) = cx + 45 for x ≥ 6 is continuous on (-∞, ∞) for all values of c except when c = 0.

The probability that the lifetime of at least one component exceeds 2 is 0.135.

Given that the joint pdf is f(x,y)=xe^(-x(1+y)) for x≥0, y≥0 and 0 otherwise as shown in attached image.

We want to find the probability that the lifetime of at least one component exceeds 2.

The probability that the lifetime of at least one component exceeds 2 is P(X>2).

\(\begin{aligned}P(X > 2)&=\int_{x=2}^{\infty}\int_{y=0}^{\infty}f(x,y)dydx\end\)

Now, we will substitute the given function, we get

\(\begin{aligned}P(X > 2)&=\int_{x=2}^{\infty}\int_{y=0}^{\infty}xe^{-x(1+y)}dydx\end\)

Further, we will simplify this, we get

\(\begin{aligned}P(X > 2)&=\int_{x=2}^{\infty}\left[-e^{-x(1+y)\right]_{0}^{\infty}dx\\ &=\int_{x=2}^{\infty}e^{-x}dx\\ &=\left[-e^{-x}\right]_{2}^{\infty}\\ &=e^{-2}\\ &=0.135\end\)

Hence, the probability that the lifetime of at least one component exceeds 2 for the joint pdf is f(x,y)=xe^(-x(1+y)) for x≥0, y≥0 and 0 otherwise as shown in attached image is 0.135.

Answer:

Angle A and L are 140 degrees each.

Step-by-step explanation:

Since GO and AL are parallel to each other, we can use the same side interior theorem to figure out angle A and L. Let's focus on GA first. We know that same side interior angles are supplementary (sum is 180 degrees). We know angle G is 40 degrees, so to figure out angle A, you do 180-40 which equals 140. So angle A is 140 degrees. You repeat this process for OL and you should also get 140 degrees for L.

Use a simple random sampling technique.

Step-by-step explanation:

Sampling is a procedure applied in statistical analysis where a fixed number of data (observations or individuals) are selected from a superior population. The approach used to select a sample from a population is determined on the basis of the type of analysis being executed.

To test for defective bulbs the store manager has to select a sample. She can select a sample of size n from the 1000 bulbs using the simple random sampling technique.

A simple random sample is a part of a statistical population in which every individual of the population has an equal probability of being selected.

Assigning each individual of the population a unique number and using a computer or random number generator for selection is a procedure to select a simple random sample.

Step-by-step explanation:

5 x 4.5 = 22.5 (km)

150 – 22.5 = 127.5 (km)

35 – 5 = 30 (km/h)

127.5/30 = 4.25 (h)

4.25 x 35 = 148.75 (km)

Alternatively,

Let x be the distance that he cycles.

x/35 + (150 – x)/5 = 4.5

x + 1050 – 7x = 157.5

6x = 892.5

x = 148.75

Ans : 148.75km.

Assuming the force is applied horizontally over a flat surface, the net horizontal force is

F (h) = 24 N - 12 N = (10 kg) a

Solve for the acceleration a :

12 N = (10 kg) a

a = 1.2 m/s²

Meanwhile, the net vertical force is zero since the box of only moving horizontally.

F (v) = n - (10 kg) g = 0

where n is the magnitude of the normal force exerted upward by the surface. We see that

n = (10 kg) (9.8 m/s²)

n = 98 N

The friction force has a magnitude that is proportional to the normal force,

12 N = μ (98 N)

where μ is the coefficient of kinetic friction. Solve for μ :

μ = (12 N)/(98 N)

μ ≈ 0.12

The answer is option B. 303.75, points come from payment history and credit mix.

To find out how many points come from Payment History, we need to multiply the borrower's credit score of 675 by the percentage for Payment History:
675 x 0.35 = 236.25
So, 236.25 points come from Payment History.

According to the given information, payment history and credit mix account for a total of 45% (35% + 10%) of a borrower's FICO score.

To find out how many points come from these categories for a borrower with a credit score of 675, we need to calculate 45% of 675.

0.45 x 675 = 303.75

Therefore,

303.75 points come from payment history and credit mix for a borrower with a credit score of 675.

To find out how many points come from Credit Mix, we need to multiply the borrower's credit score of 675 by the percentage for Credit Mix:
675 x 0.10 = 67.5
So, 67.5 points come from Credit Mix.
Adding these two amounts together, we get:
236.25 + 67.5 = 303.75

Step-by-step explanation:

First, you do the stuff in parentheses. 2+3/6 = 2.5

(a) the ordered pairs in R are \((a, b \pm \sqrt(b^2 + a^2 + b^9))\)

(b) The domain of R is \(Dom(R) = {b - z : z < = (b - b^4) or z > = (b + b^4\)), b in B}

(c) The range of R is the union of these ranges over all b in \(z < = (b - b^{(2/9)})^9\) or \(z > = (b + b^{(2/9)})^9\)

(a) To list all ordered pairs in R, we need to find all pairs (a, b) such that a R b. That is, all pairs (a, b) such that \(a^2 - b^9.\)

Since A = B - Z, we have a = b - z for some z in Z. Substituting this in the relation, we get:

\((a = b - z) ^ 2 - b^9\)

Expanding \((b - z)^2\), we get:

\(b^2 - 2bz + z^2 - b^9\)

Simplifying, we get:

\(z^2 - 2bz - (a^2 + b^9) = 0\)

This is a quadratic equation in z. Using the quadratic formula, we get:

\(z = [2b \pm \sqrt(4b^2 + 4(a^2 + b^9))] / 2\)

\(z = b \pm \sqrt(b^2 + a^2 + b^9)\)

Therefore, the ordered pairs in R are:

\((a, b \pm \sqrt(b^2 + a^2 + b^9))\)

(b) The domain of R is the set of all elements in A that are related to at least one element in B. That is:

Dom(R) = {a in A : there exists b in B such that a R b}

From the definition of R, we know that a R b if and only if \(a^2 - b^9.\) Therefore, for a to be related to some b, we need\(a^2 > = b^9\). In other words, we need:

\(a > = b^4\) or \(a < = -b^4\)

Since A = B - Z, we have a = b - z for some z in Z. Therefore, for a to be related to some b, we need:

\(b - z > = b^4\) or \(b - z < = -b^4\)

Simplifying, we get:

\(z < = (b - b^4)\) or \(z > = (b + b^4)\)

Since z is an integer, the inequalities above define a range of integers for each b. The domain of R is the union of these ranges over all b in B. Therefore, we have:

\(Dom(R) = {b - z : z < = (b - b^4) or z > = (b + b^4\)), b in B}

(c) The range of R is the set of all elements in B that are related to at least one element in A. That is:

Rng(R) = {b in B : there exists a in A such that a R b}

From the definition of R, we know that a R b if and only if \(a^2 - b^9\). Therefore, for b to be related to some a, we need \(b^9 > = a^2\). In other words, we need:

\(b > = a^{(2/9)}\) or \(b < = -a^{(2/9)}\)

Since A = B - Z, we have a = b - z for some z in Z. Therefore, for b to be related to some a, we need:

\(b - z > = (b - z)^{(2/9)}\) or \(b - z < = -(b - z)^{(2/9)}\)

Simplifying, we get:

\(z < = (b - b^{(2/9)})^9\) or \(z > = (b + b^{(2/9)})^9\)

Since z is an integer, the inequalities above define a range of integers for each b. The range of R is the union of these ranges over all b in
