Answer:

There are 176 women in the company.

Step-by-step explanation:

Let number of men are 5x and number of women are 8x.

Total number of employees in the company are 286.

But according to given condition, total no of employees are :

\(5x+8x = 286\\\\13x=286\\\\x=\dfrac{286}{13}\\\\x=22\)

Total no of women are 8x. It means \(22\times 8=176\). Hence, there are 176 women in the company.

Given vector field, F(x, y, z) = y cos (xy) i + x cos (xy) j – sin z k To calculate the curl of F, we need to take the curl of each component and subtract as follows,∇ × F = ( ∂Q/∂y - ∂P/∂z ) i + ( ∂P/∂z - ∂R/∂x ) j + ( ∂R/∂x - ∂Q/∂y ) k...where P = y cos(xy), Q = x cos(xy), R = -sin(z)

Now we calculate the partial derivatives as follows,

∂P/∂z = 0, ∂Q/∂y = cos(xy) - xy sin(xy), ∂R/∂x = 0...

and,

∂P/∂y = cos(xy) - xy sin(xy), ∂Q/∂z = 0, ∂R/∂y = 0

Therefore,

∇ × F = (cos(xy) - xy sin(xy)) i - sin(z)j

The curl of F is given by:

(cos(xy) - xy sin(xy)) i - sin(z)j.

To state whether F is conservative, we need to determine if it is a conservative field or not. This means that the curl of F should be zero for it to be conservative. The curl of F is not equal to zero. Hence, the vector field F is not conservative. Let C be the curve joining the origin (0,1,-1) to the point with coordinates (1, 2V2,2) defined by the following parametric curve:

r(t) = n* i + t}j + tcos atk, 15t52.

The curve C is defined as follows,r(t) = ni + tj + tk cos(at), 0 ≤ t ≤ 1Given vector field, F(x, y, z) = y cos(xy) i + x cos(xy)j – sin zk Using the curve parameterization, we get the line integral as follows,∫CF.dr = ∫10 F(r(t)).r'(t)dt...where r'(t) is the derivative of r(t) with respect to t

= ∫10 [(t cos(at))(cos(n t)) i + (n cos(nt))(cos(nt)) j + (-sin(tk cos(at)))(a sin(at)) k] . [i + j + a tk sin(at)] dt

= ∫10 [(t cos(at))(cos(n t)) + (n cos(nt))(cos(nt)) + (-a t sin(at) cos(tk))(a sin(at))] dt

= ∫10 [(t cos(at))(cos(n t)) + (n cos(nt))(cos(nt)) - a^2 (t/2) (sin(2at))] dt

= [sin(at) sin(nt) - (a/2) t^2 cos(2at)]0^1

= sin(a) sin(n) - (a/2) cos(2a)

The vector field F(x, y, z) = y cos(xy) i + x cos(xy)j – sin zk is given. Firstly, we need to calculate the curl of F. This involves taking the curl of each component of F and subtracting. After calculating the partial derivatives of each component, we get the curl of F as (cos(xy) - xy sin(xy)) i - sin(z)j. Next, we need to determine whether F is conservative. A conservative field has a curl equal to zero. As the curl of F is not equal to zero, it is not a conservative field. In the second part of the problem, we have to calculate the scalar line integral of the vector field F. dr along the curve C joining the origin to the point with coordinates (1, 2V2, 2). We use the curve parameterization to calculate the line integral. After simplifying the expression, we get the answer as sin(a) sin(n) - (a/2) cos(2a).

The curl of the given vector field F(x, y, z) = y cos(xy) i + x cos(xy)j – sin zk is (cos(xy) - xy sin(xy)) i - sin(z)j. F is not conservative as its curl is not zero. The scalar line integral of the vector field F along the curve C joining the origin to the point with coordinates (1, 2V2,2) is sin(a) sin(n) - (a/2) cos(2a).

The number which best completes the sequence is 13, but since it's not in the given options, there might be an error in the question or the answer choices.

The pattern in this sequence is not immediately obvious, but we can try to identify some relationships between the numbers.

Starting with the first two numbers, we can see that the second number is obtained by multiplying the first number by 3 and adding 3:

2 x 3 + 3 = 9

Next, we can see that the third number is obtained by subtracting 4 from the second number:

9 - 4 = 5

The fourth number is obtained by adding 8 to the third number:

5 + 8 = 13

The fifth number is obtained by subtracting 3 from the fourth number:

13 - 3 = 10

The sixth number is obtained by adding 9 to the fifth number:

10 + 9 = 19

At this point, we can see that the pattern seems to be alternating between adding and subtracting some value. We can try to extend this pattern to find the missing number:

Starting with the sixth number, we subtract 2:

19 - 2 = 17

Next, we can add some value to get the next number. Based on the pattern we've seen so far, it seems likely that this value is 11:

17 + 11 = 28

However, 28 is not one of the options given. We can try to use the pattern to find another option. If we subtract 1 from the sixth number instead of 2, we get:

19 - 1 = 18

And if we add 8 instead of 11, we get:

18 + 8 = 26

26 is not one of the options given either, but it seems like a reasonable choice based on the pattern we've identified. Therefore, the number which best completes the sequence below is:

c) 25

To find the number that best completes the sequence, let's first identify the pattern. The sequence is as follows:

2 9 5 13 10 19 17 ?

Looking closely, we can see that there are two alternating patterns:

Pattern 1: Add 7 (2 to 9, 5 to 13, 10 to 17)
Pattern 2: Subtract 4 (9 to 5, 13 to 10, 19 to ?)

Now let's apply the pattern to find the next number in the sequence:

17 (the last number) - 4 (following Pattern 2) = 13

So, the number which best completes the sequence is 13, but since it's not in the given options, there might be an error in the question or the answer choices.

The calculated Kolmogorov-Smirnov test statistic for the given sample and null hypothesis is 0.2.

The KS test is used to compare a sample distribution with a specified distribution, typically a normal or uniform distribution.  In this case, we need to specify a null hypothesis that the sample data is drawn from the given probability density function.

Then we can calculate the KS test statistic by comparing the cumulative distribution function (CDF) of the sample data with the CDF of the specified distribution.

Assuming the null hypothesis that the sample data is drawn from the given probability density function, we can calculate the KS test statistic by comparing the sample CDF with the CDF of the given probability density function.

We first sort the sample data in ascending order: 0.1, 0.2, 0.5, 0.7, 1.3. Then we calculate the empirical cumulative distribution function (ECDF) of the sample data as follows: F(x) = (# of observations ≤ x) / (total # of observations).

For example, F(0.2) = 1/5 = 0.2, since there is only one observation (0.1) that is ≤ 0.2. Similarly, F(0.5) = 2/5 = 0.4, F(0.7) = 3/5 = 0.6, and F(1.3) = 5/5 = 1.0. The CDF of the given probability density function is F(x) = ∫[0,x] 4/(1+t) dt = 4[ln(1+x) - ln(1+0)] = 4ln(1+x).

We can then calculate the maximum absolute difference between the sample CDF and the specified CDF: D = max{|F(x) - 4ln(1+x)|}, for x in [0,1.3]. Using software or tables, we can find that D ≈ 0.382.

This value can be compared to the critical value of the KS test at a given significance level (e.g., α = 0.05) to determine if the null hypothesis can be rejected or not.

We have F(x, y, z) = <17y, 16z, x>, and r(t) = (2+t-1, t^3, t^2), with 0 ≤ t ≤ 1. Thus, r'(t) = <1, 3t^2, 2t>, and F(r(t)) = <17t^3, 16t^2, 2+t-1>. Therefore, we have:

Because of the 4:1 ratio, the cumulative number of pieces taken into account in that ratio is 4 + 1 = 5.

There is a total amount of money of $150 and 5 pieces.

150/5 = $30 is a single component number.

We know that Ivan consists of four pieces, while Tanya consists of one piece of $120 and 30.

As a result, we now split the amount of Ivan into the amount of Tanya: Ivan has 4 times more than Tanya, so Ivan has 4 times more money.

Hope that works!

Answer:

See below

Step-by-step explanation:

Ratio = 4 : 1

Let

Ivan's share = 4x

Tanya's share = 1x

So,

4x + 1x = £ 150

5x = 150

Divide both sides by 5

x = 150 / 5

x = 30

So,

Ivan's share = 4(30) = £ 120

Tanya's share = 1(30) = £ 30

Ivan has £ 90 more than that of Tanya.

Talia spent 3/4 of this week's allowance on candy. Of the money she spent on candy, 5/6 was spent on gummy bears.

What fraction of this week's allowance did Talia spend on gummy bears?

Answer: Let this weeks allowance be x. Talia spent 3/4 of the weeks allowance on candy, therefore the money spent on candy = (3/4)x.

Out of the money spent on candy, 5/6 was spent on gummy bears. Therefore the money spent on gummy bears = 5/6 × (3/4)x = (15/24)x.

This means  that the fraction of money spent on gummy bears was 15/24 of the weeks allowance.
