When chosen 2 of the 16,701 mathematics degrees at random, the probability that at least 1 of the 2 degrees was earned by a woman is P(at least 1 women out of 2)= 70.4064%

P(women)=0.4560

We know the rule: P(not A) = 1−P(A)

We can then determine the probability of individuals who earned a degree but are not women:

P(not women) =1−P(women)=1−0.4560=0.5440

when we multiply we get,

P(A and B) = P(A)×P(B)

now we can then determine the probability of obtaining 2 individuals who earned a degree but are not women:

P(2 not women) = P(not women) × P(not women)

= 0.5440 × 0.5440 = 0.295936

now we can use the complement rule, and with this now we can then determine the probability of at least 1 degree earned by women:

P(at least 1 women out of 2) = 1−P(2 not women) = 1−0.295936

=0.704064

=70.4064%

The function that represent the growth rate of the population where y represents the population and x represents the numbers of weeks since Sabrina began her research is \(y=3.8^{x}\) (for ant colony) \(y=3.8x\) (for bee hive growth)

"A  function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)."

"Research is creative and systematic work undertaken to increase the stock of knowledge."

"The growth rate of change of population size, for a given country, territory, or geographic area, during a specified period."

As we know that we have to check the growth of the population. According to the given data, the rate of growth for ant colony is \(y=3.8^{x}\) and also the growth rate of bee hive is \(y=3.8x\)

Hence, the growth rate of ant colony is \(y=3.8^{x}\) and the growth rate of bee hive is \(y=3.8x\)

The total number of ways to travel from Earth (4,1,0) to the Wookiee Smugglers' Trading Place (11,4,3) is 18

The Millennium Falcon can travel from Earth (4,1,0) to the Wookiee Smugglers' Trading Place (11,4,3) in a total of 18 different ways. The number of ways to travel can be determined using the concept of a combination with repetitions.

The formula for combinations with repetitions is (n+k-1)!/((n-1)!*k!). For this problem, we have n = 3 and k = 8, where n is the number of dimensions of space, and k is the total distance traveled along each axis. Therefore, the total number of ways to travel is (3+8-1)!/((3-1)!*8!) = 18.

The 18 different paths are determined by the combination of the 8 steps taken along each of the three axes, with each step being either positive or negative. Therefore, each path can be written as a 3-tuple (a,b,c) where a,b, and c are the total number of positive and negative steps taken along each of the three axes.

For example, one of the paths from (4,1,0) to (11,4,3) is (5,5,5), meaning that the Millennium Falcon would travel 5 positive steps along the x-axis, 5 positive steps along the y-axis, and 5 positive steps along the z-axis.

In conclusion, the total number of ways to travel from Earth (4,1,0) to the Wookiee Smugglers' Trading Place (11,4,3) is 18, determined using the concept of combinations with repetitions.

Answer:\(-\frac{3}{10}\)

Step-by-step explanation:

Answer:

1 = 45

2 = 75

3 = 60

4 = 41

5 = 71

6 = 109

Step-by-step explanation:

This may seem tricky at first, but if you follow the order of the numbers, you can find them fairly quickly using the values already given.

For angle 1:

The angle above it of 45 degrees is similar to angle 1, so that it automatically going to be 45

For angle 2:

The same concept for angle 1 applies for angle 2, so it will be 75 degrees.

For angle 3:

All triangles add up to 180 degrees. So, since we have angles 1, and 2, solve to find 3:

180 - 45 - 75 = 60

For angle 4:

All straight lines add up to 180 degrees. So solve to find angle 4 using the value we found for angle 3:

180 - 60 - 79 = 41

For angle 5:

Angle 5 is part of another triangle and we have two of the angles already. So solve to find angle 5 using the logic used to find angle 3:

180 - 41 - 68 = 71

For angle 6:

angles 5 and 6 are part of a straight line, so use the same logic for angle 4 and solve for angle 6:

180 - 71 = 109

A: the amount of sales tax is $5.43;

B: the total cost including tax is $141.25;

C:  the amount of change you should receive is $8.75.

To find the amount of sales tax, we need to multiply the total cost of the items by the sales tax rate:

a. Sales Tax = Total Cost * Tax Rate

Sales Tax = $135.82 * 0.04

Sales Tax = $5.43

To find the total cost including tax, we add the sales tax to the total cost of the items:

b. Total Cost Including Tax = Total Cost + Sales Tax

Total Cost Including Tax = $135.82 + $5.43

Total Cost Including Tax = $141.25

To find the amount of change you should receive, we subtract the total cost including tax from the amount you gave the clerk:

c. Change = Amount Given - Total Cost Including Tax

Change = $150 - $141.25

Change = $8.75

So, the amount of sales tax is $5.43, the total cost including tax is $141.25, and the amount of change you should receive is $8.75.

The expression for calculating the perimeter of a rectangle is given by 2(l + w), where l is the length and w is the width of the rectangle. Given that the length of the rectangle is \(\frac{2}{5}\) units and the width is \(\frac{1}{5}\) units, we can substitute these values in the expression for perimeter.
Perimeter = 2(l + w)
Substituting the values of length and width, we get:
Perimeter = 2(\(\frac{2}{5}\) + \(\frac{1}{5}\))
Perimeter = 2([tax]\frac{3}{5}\))
Perimeter = \(\frac{6}{5}\)
Therefore, the perimeter of the rectangle is \(\frac{6}{5}\) units.
Hence, the correct answer is \(\frac{6}{5}\).

To find the perimeter of a rectangle with length l and width w, we can use the expression 2(l + w). Given that the length is \(\frac{2}{5}\) units and the width is \(\frac{1}{5}\) units, we can substitute these values into the expression:
Perimeter = 2(\(\frac{2}{5}\) + \(\frac{1}{5}\))
First, we add the fractions:
\(\frac{2}{5}\) + \(\frac{1}{5}\) = \(\frac{3}{5}\)

Now, we multiply the result by 2:
2 * \(\frac{3}{5}\) = \(\frac{6}{5}\)
The perimeter of the rectangle is \(\frac{6}{5}\) units, which is equivalent to 1\(\frac{1}{5}\) units.

(i) The dual of the given LP problem can be found by following these steps:

1. For each constraint in the primal problem, create a dual variable. In this case, we have three constraints, so we'll have three dual variables: y1, y2, and y3.
2. The objective function of the dual problem will be the sum of the products of the primal variables and their corresponding dual variables. So, the dual objective function is:
  Maximize w = 3y1 + 2y2 + y3.
3. For each primal variable x, create a constraint in the dual problem with the coefficient of the corresponding dual variable equal to the coefficient of x in the primal objective function. So, the dual constraints are:
  y1 + 2y2 - y3 ≤ -2
  y1 + y2 + y3 ≤ -1
  y1, y2, y3 ≥ 0.

(ii) To find the optimal solution to the dual problem, we need to solve the optimal tableau of the dual problem. From the given information, we know that Row 0 of the optimal tableau is:
  w = 4x1 + e2 + (M-1)a2 + (M+2)a3 = 0.
 
  However, the given information does not provide any details about the values of x1, e2, a2, or a3. Therefore, without this information, we cannot determine the specific optimal solution to the dual problem.
