The equation obtained for Kim will be t = x/2

Equation obtained for Jake will be t = (x - 6)/1.5

As for the problem, Kim and Jake are competing in the big race. And the values of their speed are given below.

Kim moves at a 2-meter-per-second running pace.

Jake moves at a 1.5 meter per second running pace (3 meters per 2 seconds)

Jake gets 6 meters ahead of Kim.

To get equations for the same case to both persons we should get it as,

Let x be the complete race distance and t be either Kim's or Jake's total race time.

Time = Speed/Distance

Kim's time equation is t = x/ 2.

The time equation that Jake uses is t = (x - 6)/1.5.

Answer:

median = 3.5

Step-by-step explanation:

the median is the middle value of the data sey. If there is no exact middle then it is the average of the values either side of the middle.

listing the values from the data set

1 , 1 , 2, 3 ,  4 , 4 , 4 , 5

               ↑ middle

median = (3 + 4) ÷ 2 = 7 ÷ 2 = 3.5

A distribution is a way of displaying data, consisting of three primary components: shape, center, and spread. The shape is the overall pattern of the distribution, while the center is the point where the distribution is balanced. The spread is the range of values of the data, often measured by the standard deviation or the interquartile range (IQR). The distribution can be visualized through graphs like histograms, box plots, or scatter plots.

A brief description of a distribution should include its shape, center, and spread. The spread is the term that should be included in the blank space.A distribution can be described as a way of displaying data. It gives us an idea about how the data are spread out.

The three primary components of any distribution are the shape, center, and spread. Shape refers to the overall pattern of the distribution. It tells us whether the data are symmetric or skewed. The symmetry means that the left half of the distribution is a mirror image of the right half, whereas a skewed distribution is not symmetrical. The tail of a distribution describes the spread of a skewed distribution. It refers to the parts of the distribution that extend out from the center of the graph.The center refers to the point where the distribution is balanced. In symmetric distributions, the center is the same as the mean and median. However, in a skewed distribution, the mean and median differ from each other.

The spread refers to the range of values of the data. It tells us how much the data are scattered or spread out. A small spread indicates that the data points are close to each other, while a large spread suggests that the data points are far from each other. It is often measured by the standard deviation or the interquartile range (IQR).The distribution of data can be visualized through different graphs like histograms, box plots, or scatter plots.

Answer:

C

Step-by-step explanation: A.P.E.X

The curl of the vector field

curl(F) = -2ey cos(z)i + 8ez cos(x)j - 9ex cos(y)k

The divergence of the vector field

div(F) = 9e^x sin(y) + 2e^y sin(z) + 8e^z

To find the curl of the vector field F(x, y, z) = 9ex sin(y), 2ey sin(z), 8ez sin(x), we need to compute the determinant of the curl matrix.

(a) Curl of F:

The curl of a vector field F = P(x, y, z)i + Q(x, y, z)j + R(x, y, z)k is given by the following formula:

curl(F) = (∂R/∂y - ∂Q/∂z)i + (∂P/∂z - ∂R/∂x)j + (∂Q/∂x - ∂P/∂y)k

In this case, we have:

P(x, y, z) = 9ex sin(y)

Q(x, y, z) = 2ey sin(z)

R(x, y, z) = 8ez sin(x)

Taking the partial derivatives, we get:

∂P/∂y = 9ex cos(y)

∂Q/∂z = 2ey cos(z)

∂R/∂x = 8ez cos(x)

∂R/∂y = 0 (no y-dependence in R)

∂Q/∂x = 0 (no x-dependence in Q)

∂P/∂z = 0 (no z-dependence in P)

Substituting these values into the curl formula, we have:

curl(F) = (0 - 2ey cos(z))i + (8ez cos(x) - 0)j + (0 - 9ex cos(y))k

= -2ey cos(z)i + 8ez cos(x)j - 9ex cos(y)k

Therefore, the curl of the vector field F is given by:

curl(F) = -2ey cos(z)i + 8ez cos(x)j - 9ex cos(y)k

(b) Divergence of F:

The divergence of a vector field F = P(x, y, z)i + Q(x, y, z)j + R(x, y, z)k is given by the following formula:

div(F) = ∂P/∂x + ∂Q/∂y + ∂R/∂z

In this case, we have:

∂P/∂x = 9e^x sin(y)

∂Q/∂y = 2e^y sin(z)

∂R/∂z = 8e^z

Substituting these values into the divergence formula, we have:

div(F) = 9e^x sin(y) + 2e^y sin(z) + 8e^z

Therefore, the divergence of the vector field F is given by:

div(F) = 9e^x sin(y) + 2e^y sin(z) + 8e^z

Answer:

2/15 or 0.1333

Step-by-step explanation:

Answer:

a) The Mode is the number of cubes with the greatest frequency. In this case, I believe that to be 2, as 2 has a frequency of 7, the largest frequency there, I think, however the numbers are very blurry.

b) Total number of adults asked is the total frequency. In this case, that would be 5 + 5 + 7 + 4 + 3 + 2 (I think, again the numbers are hard to make out) which, if I'm correct, would equal 26

c) Total number of coffee drank, I believe you would multiply the number of cups with their frequency each. In this case:

0 × 5 = 0

1 × 5 = 5

2 × 7 = 14

3 × 4 = 12

4 × 3 = 12

5 × 2 = 10

(if I have read the numbers correctly)

Now, you add these totals together, so:

0 + 5 + 14 + 12 + 12 + 10 which gives you 53 total.

d) To calculate the mean of data in a table, firstly, you do the same thing as what question c asks, and multiply the number of cups with their frequencies, which we have already done here, and you add that total, which we have found to be 53 (if all went well with my ability to read the blurry numbers)

Now, there's one final step, you need to divide this number, so 53, by the total frequency, which in part b we found to be 26.

53 ÷ 26 gives us 2.038 which we could round to 2.04

a. All states are positive recurrent, the Markov chain is recurrent.

b. The Markov chain has two absorbing states, it is transient.

c. All states are positive recurrent, the Markov chain is recurrent.

d. The Markov chain has one absorbing state, it is transient.

a. The Markov chain with transition matrix P1 has 3 states: state 1, state 2, and state 3. To determine if they are transient or recurrent, we need to check if any state is reachable from every other state. It can be shown that all states communicate with each other, so the Markov chain is irreducible. Moreover, since all states are positive recurrent, the Markov chain is recurrent.

b. The Markov chain with transition matrix P2 has 5 states: state 1, state 2, state 3, state 4, and state 5. To determine if they are transient or recurrent, we need to check if any state is reachable from every other state. However, it is clear that state 4 and state 5 are absorbing states and can only transition to themselves. Therefore, these states are not reachable from any other state, and the Markov chain is not irreducible. Moreover, since the Markov chain has two absorbing states, it is transient.

c. The Markov chain with transition matrix P3 has 5 states: state 1, state 2, state 3, state 4, and state 5. To determine if they are transient or recurrent, we need to check if any state is reachable from every other state.

Answer:

The constant of proportionality is \(\frac{9}{2}\)

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities

To find the constant of proportionality from the given graph choose a point on the line and substitute x and y in the equation of the proportionality by the coordinates of the point.

∵ Point (4, 18) lies on the line

∴ x = 4, y = 18

∵ The equation is y = kx

→ Substitute x by 4 and y by 18

∴ 18 = k(4)

∴ 18 = 4k

→ Divide both sides by 4 to find k

∴ \(\frac{18}{4}=\frac{4k}{4}\)

∴ \(\frac{18}{4}=k\)

→ Simplify the fraction by dividing up and down by 2

∴ \(\frac{9}{2}=k\)

∴ The constant of proportionality is \(\frac{9}{2}\)

Answer:

157.5°

Step-by-step explanation:

Total size of interior angles=(2n-4)90°

(2x16-4)90= 2520

size of one interior angle= (2n-4)90°/n

2520/16

Answer= 157.5°

NB n is the number of sides

The size of the interior angle of a regular 16-sided polygon would be 157.5 degrees.

A regular polygon is a flat shape whose sides are all equal and whose angles are all equal.

The formula for finding the sum of the measure of the interior angles is,

S = (n - 2) × 180.

We have to give that,

A regular-sided polygon has 16 sides.

Using the formula for a regular polygon of n sides would be,

Each interior angle = \(\dfrac{(2n - 4) \times 90 deg}{n}\)

Here, we have the sides of the regular polygon;

n = 16

Hence substitute n = 16 in above formula,

Each interior angle = \(\dfrac{(2n - 4) \times 90 deg}{n}\)

                                \(= \dfrac{(2\times 16 - 4) \times 90 deg}{16}\)

                                \(= \dfrac{(28) \times 90 deg}{16}\)

                              \(= 157.5 \ \text{degree}\)

Therefore, The size of the interior angle would be, 157.5 degrees.
