Answer:

the answer is irrational

Answer:

A

Step-by-step explanation:

The quotient is  5x³ -5x² + 2x -2.

Synthetic division is typically used to identify the zeroes of polynomials and is described as "a simplified method of dividing a polynomial with another polynomial equation of degree 1." This division method requires less human calculation effort than the lengthy division method.

Given:

(5\(x^4\) – 3x² + 4) ÷ (x + 1)

So, the division is

                       (x+1) |  (5\(x^4\) – 3x² + 4) | 5x³ -5x² + 2x -2

                                   5\(x^4\) + 5x³

                               ___________

                                          -5x³ - 3x²

                                          -5x³ - 5x²  

                                       ____________

                                                    2x² + 4    

                                                    2x² + 2x      

                                              ____________

                                                              4 - 2x      

                                                              -2 - 2x

                                                             _______

                                                                    6

Hence, the quotient is  5x³ -5x² + 2x -2.

Step-by-step explanation:

The end of the plank is sliding along the ground at a rate of approximately -0.08 m/s when it is 1.4 meters from the wall of the building. The negative sign indicates that the end of the plank is sliding in the opposite direction.

To find how fast the end of the plank is sliding along the ground, we can use related rates. Let's consider the position of the end of the plank as it moves along the ground.

Let x be the distance between the end of the plank and the wall of the building, and y be the distance between the end of the plank and the ground. We are given that dx/dt = 0.26 m/s, the rate at which the worker pulls the rope.

We can use the Pythagorean theorem to relate x and y:

x² + y² = 5²

Differentiating both sides of the equation with respect to time, we get:

2x(dx/dt) + 2y(dy/dt) = 0

At the given moment when x = 1.4 m, we can substitute this value into the equation above and solve for dy/dt, which represents the rate at which the end of the plank is sliding along the ground.

2(1.4)(0.26) + 2y(dy/dt) = 0

2(0.364) + 2y(dy/dt) = 0

0.728 + 2y(dy/dt) = 0

2y(dy/dt) = -0.728

dy/dt = -0.728 / (2y)

To find y, we can use the Pythagorean theorem:

x² + y² = 5²

(1.4)² + y² = 5²

1.96 + y² = 25

y² = 23.04

y = √23.04 ≈ 4.8 m

Substituting y = 4.8 m into the equation for dy/dt, we have:

dy/dt = -0.728 / (2 * 4.8) ≈ -0.0757 m/s

thats the option which represents the question asked

a) The expected number of people who would name chocolate in the sample is approximately 6.30. b) The probability of exactly eight people naming chocolate is given by  \(P(X = 8) = (14 C 8) (0.45^8) (1 - 0.45)^{(14 - 8)\)

c) The probability of eight or more people naming chocolate sum the probabilities of exactly eight, nine, ten, eleven, twelve, thirteen, and fourteen people naming chocolate

(a) To find the expected number of people who would name chocolate in the sample, we multiply the percentage of people who prefer chocolate by the sample size. In this case, 45% is equivalent to 0.45, so we calculate the expected number as 0.45 * 14 = 6.30. Rounding to two decimal places, we expect approximately 6.30 people in the sample to name chocolate.

(b) To calculate the probability of exactly eight people naming chocolate, we use the binomial probability formula. The formula is \(P(X = k) = (n C k) * p^k * (1 - p)^{(n - k)\), where n is the sample size, k is the number of successes (people naming chocolate), p is the probability of success (45% or 0.45), and (n C k) represents the number of combinations. Substituting the values, we have \(P(X = 8) = (14 C 8) * (0.45^8) * (1 - 0.45)^{(14 - 8)\). Evaluating this expression gives us the probability of exactly eight people naming chocolate.

(c) To find the probability of eight or more people naming chocolate, we sum the probabilities of exactly eight, nine, ten, eleven, twelve, thirteen, and fourteen people naming chocolate. Using the same binomial probability formula as before, we calculate the probabilities for each number of successes and add them together to obtain the probability of eight or more people naming chocolate.

There are a total of (10 choose 5) possible ways to randomly group the 10 kids into two teams of 5. The probability that Alex and Jose end up on the same team is 7/31 or approximately 0.2258 (rounded to 4 decimal places). This is because we are choosing 5 kids out of 10 for one team, and the remaining 5 kids automatically make up the other team.

To calculate the probability of Alex and Jose ending up on the same team, we can think of it as choosing 3 more kids to be on their team out of the remaining 8 kids. There are (8 choose 3) ways to do this. Therefore, the probability of Alex and Jose ending up on the same team is:
(8 choose 3) / (10 choose 5) = 0.357 or approximately 35.7%
So there is a 35.7% chance that Alex and Jose will end up on the same team when the 10 kids are randomly grouped into an A team and a B team.
Since the 10 kids are randomly grouped into two teams, we can use combinations to determine the possible groupings. The total number of ways to divide the kids into two groups of 5 is given by the combination formula:
Total groupings = C(10, 5) = 10! / (5! * 5!) = 252
Now, let's consider the groupings where Alex and Jose are on the same team. There are 8 other kids left, and we need to select 3 of them to complete the team of 5. So, the number of groupings with Alex and Jose together is given by:
Groupings with Alex and Jose together = C(8, 3) = 8! / (3! * 5!) = 56
Finally, we can find the probability of Alex and Jose being on the same team by dividing the number of groupings with them together by the total groupings:
Probability = (Groupings with Alex and Jose together) / (Total groupings) = 56 / 252 = 7/31
So, the probability that Alex and Jose end up on the same team is 7/31 or approximately 0.2258 (rounded to 4 decimal places).

If segment BD is congruent to segment BC, and BD = 4x - 18, BC = x + 3, and AC = 34, then AB = 31/x.

Let the equation be AB + BC = AC

substitute the values in the above equation, we get

AB + x + 3 = 34

simplifying the value of x,

Subtract A B from both sides AB + x + 3 - AB = 34 - A B

x + 3 = 34 - AB

Subtract 3 from both sides,

x + 3 - 3 = 34 - AB - 3

x = -AB + 31

Plug in this value of x into the line segments to find BC and AC.

Where, BC = x + 3

substitute the value of x in the above equation, we get

BC = [-AB + 31 ] + 3

BC = -AB + 34

Then, AB + BC = AC

x = -AB + 31

AB = 31/x

Hence, If segment BD is congruent to segment BC, and BD = 4x - 18,

BC = x + 3, and AC = 34, then AB = 31/x.

The percentage she earned as commission from sales is 7.2%

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%". The term "percentage" was adapted from the Latin word "per centum", which means "by the hundred". Percentages are fractions with 100 as the denominator. In other words, it is the relation between part and whole where the value of whole is always taken as 100. a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100.

a) Height = 62.14112783 + 2.05671274 * Diameter at breast height + 15.64180216 * Bark thickness.

b) The slopes indicate the impact of diameter at breast height and bark thickness on tree height.

c) The model is significant (p < 0.05) with a high R Square (0.78578312), indicating good predictability of height based on variables.

a) The different relapse condition can be expressed as:

Level = 62.14112783 + 2.05671274 * Width at bosom level + 15.64180216 * Bark thickness

b) The two slants in the situation address the connection between the level of a California redwood tree and the width at bosom level (DBH) and the bark thickness.

The slant for the distance across at bosom level (DBH) is 2.05671274. This shows that for each unit expansion in the DBH of a tree, the anticipated level of the tree increments by roughly 2.06 units, it are held consistent to expect any remaining factors.

The slant for bark thickness is 15.64180216. This proposes that for each unit expansion in the bark thickness of a tree, the anticipated level of the tree increments by roughly 15.64 units, expecting any remaining factors continue as before.

c) The discoveries show that the various relapse model is genuinely huge in foreseeing the level of California redwood trees.

The p-values for both the breadth at bosom level and bark thickness are not exactly the customary edge of 0.05, showing that the two factors have a critical relationship with the level of the trees.

The F-measurement (33.01349577) is likewise critical with an exceptionally low p-esteem (9.50E-07), showing that the general model is ideal for the information.

The coefficient of assurance (R Square) is 0.78578312, demonstrating that around 78.6% of the changeability in the level of the redwood trees can be made sense of by the relapse model.

The changed R Square (0.761981244) represents the quantity of indicators and changes the R Square worth as needs be.

The standard blunder (22.59816752) addresses the typical distance between the noticed qualities and the anticipated qualities by the model.

Answer: x = -4 and x = 2.

To factor a quadratic equation in the form of x^2 + bx + c = 0, we need to find two numbers that when multiplied together, give us c, and when added or subtracted, give us b.

We need to find two numbers whose product is -8 and whose sum is 2. These numbers are 4 and -2, so we can write:

x^2 + 2x - 8 = (x + 4)(x - 2) = 0

Setting each factor to zero, we get:

x + 4 = 0 or x - 2 = 0

Solving for x in each equation, we get:

x = -4 or x = 2

So, the solutions to the equation x^2 + 2x - 8 = 0 are x = -4 and x = 2.

To conduct a test of hypothesis to compare the mortality rates of rice weevils exposed to nitrogen gas for different exposure times, we need to formulate the null and alternative hypotheses. The null hypothesis (H^0) states that there is no significant difference in the mortality rates between the two exposure times, while the alternative hypothesis (H^a) states that there is a significant difference.

In this case, let p^1 represent the proportion of rice weevils found dead in the first experiment and p^2 represent the proportion of rice weevils found dead in the second experiment. The null hypothesis (H^0) is that the difference in proportions (p^1 - p^2) is equal to zero, indicating no difference in mortality rates. The alternative hypothesis (H^a) is that the difference in proportions is not equal to zero, indicating a significant difference in mortality rates between the two exposure times.
