Answers

Answer:

A. Increasing by 4%.

Step-by-step explanation:

Answer:

A) The price of product A is increasing by 3% per year.

(B) The product A recorded a greater percentage change in price over the previous year.

Step-by-step explanation:

(A)

The function representing the price, in dollars, of product A after x years is:

FA(x)=0.69*(1.03)x

The function  FA(x)can be written as:

FA(x)=0.69*1+(0.03)x

The function FA(x) is similar to the exponential growth function, y=a(1+r)x .

Here r is the growth rate.

Thus, it can be said that the price of product A is increasing by 3% per year.

(B)

Consider the data of product B for the year 3 and 4.

The price of product B for year 3 and 4 are 10,303.01 and 10,406.04.

Compute the percent price change from year 3 to 4 as follows:

10406.04-10303.01/10303.01*100

which is 0.999%

~1%

The price of product B is increasing by 1% per year.

Thus, the product A recorded a greater percentage change in price over the previous year.

A bakery produces five types of bagels, two of which are chocolate chip and cinnamon raisin.

(a) If there are at least 10 bagels of each type, how many different selections of 10 bagels are there?

(b) Suppose there are only 3 chocolate chip and 2 cinnamon raisin bagels, but at least 10 of the other three types. How many different selections of 10 bagels are there?

Answers

a) If there are at least 10 bagels of each type, we can calculate the number of different selections of 10 bagels by using the concept of combinations. Since there are 5 types of bagels and we need to select 10 bagels, the calculation can be done as follows:

[tex]\(\binom{10+5-1}{10} = \binom{14}{10}\)[/tex]

b) If there are 3 chocolate chip and 2 cinnamon raisin bagels, and at least 10 of the other three types, we can calculate the number of different selections of 10 bagels using the same concept of combinations. In this case, we have 3 types of bagels (excluding chocolate chip and cinnamon raisin) with at least 10 bagels each. So the calculation becomes:

[tex]\(\binom{10+3-1}{10} = \binom{12}{10}\)[/tex]

Find the flux of the given vector field F across the upper hemisphere x^2 + y^2 + z^2 = a^2, z >= 0. Orient the hemisphere with an upward-pointing normal.
19. F= yj
20. F = yi - xj
21. F= -yi+xj-k
22. F = x^2i + xyj+xzk

Answers

6πa² is the flux of F across the upper hemisphere.

The problem requires us to compute the flux of the given vector field F across the upper hemisphere x² + y² + z² = a², z ≥ 0. We are to orient the hemisphere with an upward-pointing normal. The four vector fields are:

F = yj

F = yi - xj

F = -yi + xj - kz

F = x²i + xyj + xzk

To begin with, we'll make use of the Divergence Theorem, which states that the flux of a vector field F across a closed surface S is equivalent to the volume integral of the divergence of the vector field over the region enclosed by the surface, V, that is:

F · n dS = ∭V (div F) dV

where n is the outward pointing normal unit vector at each point of the surface S, and div F is the divergence of F.

We'll need to write the vector fields in terms of i, j, and k before we can compute their divergence. Let's start with the first vector field:

F = yj

We can rewrite this as:

F = 0i + yj + 0k

Then, we compute the divergence of F:

div F = d/dx (0) + d/dy (y) + d/dz (0)

= 0 + 0 + 0 = 0

So, the flux of F across the upper hemisphere is 0. Now, let's move onto the second vector field:

F = yi - xj

We can rewrite this as:

F = xi + (-xj) + 0k

Then, we compute the divergence of F:

div F = d/dx (x) + d/dy (-x) + d/dz (0)

= 1 - 1 + 0 = 0

So, the flux of F across the upper hemisphere is 0. Let's move onto the third vector field:

F = -yi + xj - kz

We can rewrite this as:

F = xi + y(-1j) + (-1)k

Then, we compute the divergence of F:

div F = d/dx (x) + d/dy (y(-1)) + d/dz (-1)

= 1 - 1 + 0 = 0

So, the flux of F across the upper hemisphere is 0. Lastly, let's consider the fourth vector field:

F = x²i + xyj + xzk

We can compute the divergence of F directly:

div F = d/dx (x²) + d/dy (xy) + d/dz (xz)

= 2x + x + 0 = 3x

Then, we express the surface as a function of spherical coordinates:

r = a, 0 ≤ θ ≤ 2π, 0 ≤ φ ≤ π/2

Note that the upper hemisphere corresponds to 0 ≤ φ ≤ π/2.

We can compute the flux of F over the hemisphere by computing the volume integral of the divergence of F over the region V that is enclosed by the surface:

r² sin φ dr dφ dθ

= ∫[0,2π] ∫[0,π/2] ∫[0,a] 3r cos φ dr dφ dθ

= ∫[0,2π] ∫[0,π/2] (3a²/2) sin φ dφ dθ

= (3a²/2) ∫[0,2π] ∫[0,π/2] sin φ dφ dθ

= (3a²/2) [2π] [2] = 6πa²

Therefore, the flux of F across the upper hemisphere is 6πa².

2.1. let a be the event that 2 consecutive flips both yield heads and let b be the event that the first or last flip yields tails. prove or disprove that events a and b are independent.

Answers

The events A and B are not independent. The occurrence of event B affects the probability of event A.

To determine whether events A and B are independent,

we need to check if the probability of event A occurring is affected by the occurrence of event B, and vice versa.

Probability of event A: Since we are flipping two coins,

the probability of getting heads on each flip is 1/2.

Therefore, the probability of getting two consecutive heads is

[tex](1/2) \times (1/2) = 1/4[/tex]

Probability of event B: The first or last flip yielding tails means there are two possibilities:

either the first flip is tails and the second flip is any outcome,

or the first flip is any outcome and the second flip is tails.

Each of these individual possibilities has a probability of

[tex](1/2) \times (1/2) = 1/4[/tex]

Hence, theprobability of event B is 1/4 + 1/4 = 1/2.

Since the probability of event A is 1/4 and the probability of event B is 1/2, and 1/4 ≠ 1/2,

we can conclude that events A and B are not independent.

The occurrence of event B (first or last flip yielding tails) affects the probability of event A (two consecutive flips yielding heads).

Which golf ball went higher, and how many feet? (Desmos!)

Answers

Answer:

1. 36

2. Second

Step-by-step explanation:

- For the first ball, we can see the given function:

[tex]f(x)=-16(t^{2}-3t )[/tex]

[tex]=-16[t^{2} -3t+(3/2)^{2}-(3/2)^{2} ][/tex]

[tex]=-16(t-\frac{3}{2} )^{2} +(-\frac{3}{2} )^{2} *(-16)[/tex]

[tex]-16(t-\frac{3}{2} )^{2} +36[/tex]

So the vertex is ([tex]\frac{3}{2}[/tex], 36), it means when the ball was hit by the [tex]\frac{3}{2}[/tex] seconds, it arrived at the highest height of 36 feet.

- For the second ball, we can see the given graph: the vertex is (2,64), it means when the ball was hit by the 2 seconds, it arrived at the highest height of 64 feet.

- Compare to the two heights, 36 (first ball) is less than 64 (second ball), so the second ball went higher.

How many permutations of S9, have cycle strucrure 3^3?

Answers

There is only 1 permutation in S9 with a cycle structure of [tex]3^3[/tex].

To find the number of permutations of S9 with a cycle structure of [tex]3^3[/tex], we can use the concept of cycle index.

In a permutation with a cycle structure of[tex]3^3[/tex], we have three cycles of length 3. The cycle index of S9 with respect to cycles of length 3 can be determined using the Polya enumeration theorem.

The cycle index of S9 with respect to cycles of length 3 is given by:

[tex]Z(S9, t1, t2, t3) = (t1^3 + t3^3)^3[/tex]

Expanding this expression, we get:

[tex]Z(S9, t1, t2, t3) = (t1^3 + t3^3)^3\\\= (t1^9 + 3t1^6t3^3 + 3t1^3t3^6 + t3^9)[/tex]

To count the number of permutations with the desired cycle structure, we need to find the coefficient of the term [tex]t1^9t3^9[/tex].

From the expanded form, we see that the coefficient  [tex]t1^9t3^9[/tex] is 1.

Therefore, there is only one permutation in S9 with a cycle structure of [tex]3^3[/tex]

In summary, there is 1 permutation of S9 that has a cycle structure of [tex]3^3[/tex].

Answer: C. K= 2.5

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

[tex]\Huge\boxed{k=2.5}[/tex]

Step-by-step explanation:

Given -2.1k + 13 + 6.5k = 24 we need to isolate the variable using inverse operations

step 1 combine any like terms

sometimes there are not like terms but in this case there are. When there are like terms (must be on the same side of the = ) you add them together

-2.1k + 6.5k = 4.4k

now we have

4.4k + 13 = 24

Now we want to get rid of the 13

To do so we subtract 13 from each side

13 - 13 cancels out

24 - 13 = 11

now we have 4.4k=11

now we want to get rid of the 4.4

To do so we divide each side by 4.4

4.4k/4=k

11/4.4=2.5

we're left with k - 2.5

Find all possible trigonometric ratios given the following:

tan θ = -7/24 and cos θ > 0

Answers

The given information allows us to find the values of trigonometric ratios involving angle θ. Given that tan θ = -7/24 and cos θ > 0, we can determine the following trigonometric ratios: sin θ, csc θ, sec θ, and cot θ

We are given that tan θ = -7/24. Using this information, we can determine the values of sin θ and csc θ.

Since tan θ = sin θ / cos θ, we can write -7/24 = sin θ / cos θ. Rearranging the equation, sin θ = -7 and cos θ = 24.

Now, we can find the values of csc θ, sec θ, and cot θ.

csc θ is the reciprocal of sin θ, so csc θ = 1 / sin θ = 1 / (-7) = -1/7.

To find sec θ, we use the fact that sec θ = 1 / cos θ. So, sec θ = 1 / (24) = 1/24.

Lastly, to calculate cot θ, we know that cot θ = 1 / tan θ. Thus, cot θ = 1 / (-7/24) = -24/7.

In summary, given tan θ = -7/24 and cos θ > 0, we have sin θ = -7, csc θ = -1/7, sec θ = 1/24, and cot θ = -24/7.

Suppose that 5 people should be randomly selected from a group of 20 forming couples by 10. What is the probability that the 5 unrelated chosen from related persons (that is, no chosen person be a couple)?

Answers

The probability that none of the 5 randomly selected individuals are part of a couple is 0.016.

What is the probability that none of the 5 randomly selected individuals are part of a couple?

A probability means the branch of math which deals with finding out the likelihood of the occurrence of an event. Its measures the chance of an event happening.

We will know total number of possible outcomes when selecting 5 individuals from a group of 20. This can be calculated using the combination formula:

C(20, 5) = 20! / (5! * (20 - 5)!)

C(20, 5) = 15,504

We know that when we select an individual, we are removing their corresponding partner from the pool of available choices. This means that for each individual we choose, the number of available choices decreases by 1.

The number of favorable outcomes can be calculated as follows:

= 20 * 18 * 16 * 14 * 12

= 967,680

The probability will be:

= Outcomes / Favorable outcomes

= 15,504 / 967,680

= 0.01602182539

= 0.016.

Answers

a. The volume of the solid is 24 cubic units.

b. The volume of the solid is 4π cubic units.

How to calculate tie value

a. Volume = Area of Base * Height

The base is a right triangle with base length of 3 units and height of 4 units. The area of the base can be calculated as:

Area of Base = (1/2) * base * height

= (1/2) * 3 * 4

= 6 square units

The height of the solid is 4 units.

Volume = Area of Base * Height

= 6 * 4

= 24 cubic units

b) Any cross section of the solid, taken parallel to the y-axis and perpendicular to the x-axis, is a semicircle.

Volume = (1/2) * π * radius² × height

Volume = (1/2) * (1/2) * π * 2² * 4

= (1/4) * π * 4 * 4

= π * 4

Therefore, the volume of the solid is 4π cubic units.

Answer : i) The probability of finding the first case in 4 trials is 0.1024                        ii) The probability that the team must select more than 6 people before finding one who has a corona virus is 0.4095.

Explanation : Given information:Let p is the probability that he succeeds in finding such a person, is 0.2 and X denote the number of people asked until the first success.

(i) What is the probability that the team must select 4 people until he finds one who has a corona virus?  

The number of trials required until the first success follows geometric distribution.          

The probability of finding the first case in 4 trials is: P(X = 4) = q^3p, where q = 1 - p.                                                                                                                                     We have p = 0.2 and q = 0.8. So, P(X = 4) = 0.8^3 × 0.2 = 0.1024

(ii) What is the probability that the team must select more than 6 people before finding one who who has a corona virus?                                                                                                                                                                        P(X > 6) = 1 - P(X ≤ 6)                                                                                          The probability of finding the first case in the first 6 trials is:P(X ≤ 6) = 1 - q^6p= 1 - 0.8^6 × 0.2= 0.59049P(X > 6) = 1 - P(X ≤ 6)= 1 - 0.59049= 0.4095                                                                                                                Therefore, the probability that the team must select more than 6 people before finding one who has a corona virus is 0.4095.
