Answer:

1) 6 (the answer is 6)

Step-by-step explanation:

First, let's calculate how much the textbooks cost in total: 30 textbooks * $116.00/textbook = $<<30*116=3480.00>>3480.00

Then, let's subtract the cost of the textbooks from the total amount of money the math department has available: $6500.00 - $3480.00 = $<<6500-3480=3015.00>>3015.00

Finally, we can divide the amount of money the math department has left by the cost of each laptop to determine how many laptops they can afford: $3015.00 / $439.00/laptop = 6.83 laptops

Since it's not possible to buy a fraction of a laptop, the math department can only buy 6 laptops. Therefore, the answer is 6, which corresponds to choice (1).

The differential equation that models this situation is dx/dt = kx(M - x) (option c).

To determine the differential equation that models the situation, let's analyze the problem statement.

The rate at which a person can memorize a list of M words is proportional to the product of the number of words memorized and the number of words that have not been memorized.

Let's denote the number of words memorized as "a" and the number of words not yet memorized as "M - a" (where M is the total number of words in the list).

The problem states that the rate of memorization is proportional to the product of "a" and "M - a". We can express this mathematically as:

Rate of memorization ∝ a * (M - a)

To convert this proportionality into an equation, we introduce a positive constant k:

Rate of memorization = k * a * (M - a)

The left side of the equation represents the rate of change of the number of words memorized (da/dt), and the right side represents the product of "a" and "M - a" multiplied by the constant k.

Therefore, the differential equation that models this situation is:

da/dt = k * a * (M - a)

Comparing this with the given options, we can see that the correct choice is option C:

dx/dt = k * x * (M - x)

The complete question is:

At any time t > 0 the rate at which a person can memorize a list of M words is proportional to the product of the number of words memorized and the number of words that have not been memorized. If a denotes the number of words memorized at time t, which differential equation models this situation? Assume k is a positive constant.

A. dx/dt = kx

B. dx/dt = kx(x - M)

C. dx/dt = kx(M - x)

D. dx/dt = kt(M - t)

Total length of wire = 8.33 + 6.67 + 5.33 + ...20 terms= 100[2 - 0.8^20] / [1.2]≈ 80.99 feet Since the total length of wire required is less than the available wire, Sonja will have enough wire.

Given, Sonja cuts 100 inches for the first piece, 80 inches for the second piece, and 64 inches for the third piece. We need to find the explicit formula for the nth piece.We can see that Sonja is cutting wire in decreasing order of 20%.So, the explicit formula for the nth piece can be given by an = a1 * r^(n-1)where a1 = 100 and r = 0.8 Thus, the explicit formula for the nth piece can be given byan = 100 * (0.8)^(n-1)Now, we need to find if Sonja has enough wire for the mobile as she only has 40 feet of wire to use for the project and wants to cut 20 pieces total for the mobile using her pattern.We know that 1 inch = 0.0833 feet 100 inches = 100 * 0.0833 feet = 8.33 feet80 inches = 80 * 0.0833 feet = 6.67 feet64 inches = 64 * 0.0833 feet = 5.33 feet Now, we can find the total length of wire Sonja needs to cut 20 pieces.

In the execution of the Simplex Algorithm, a variable that is extracted from the basis can never re-enter the basis at the very next step due to the optimality conditions and pivoting operations. Here's a step-by-step explanation:

1. Simplex Algorithm is an iterative method for solving linear programming problems.
2. The algorithm starts with an initial feasible solution (basis) and searches for an improved solution by changing the basis (swapping non-basic and basic variables).
3. At each iteration, the algorithm selects a non-basic variable to enter the basis (entering variable) and a basic variable to leave the basis (leaving variable). This is done by pivoting on the element corresponding to the entering and leaving variables in the tableau.
4. The pivot operation enforces that the objective function value improves in each step by increasing (maximization problem) or decreasing (minimization problem) the value of the entering variable.
5. After the pivot operation, the new solution is still feasible, and the entering variable becomes part of the basis while the leaving variable becomes non-basic.
6. The algorithm terminates when no more improvement in the objective function value is possible, meaning that an optimal solution has been found or the problem is unbounded.

Since the entering variable is chosen to improve the objective function, and the pivot operation enforces an improvement, the variable that has just left the basis cannot re-enter at the very next step. If it were to re-enter, it would negate the improvement achieved in the previous step, violating the optimality conditions of the Simplex Algorithm.

The correct answer is option B.  17

Step-by-step explanation:

It is given that, ZX bisects ∠WZY. If the measure of ∠YXZ is (6m – 12)°

To find the value of m

From the figure we can see that, triangle WYZ is an isosceles  triangle.

ZW = ZY

Then <YXZ = <WXZ = 90°

It is given ∠YXZ  = (6m – 12)°

(6m – 12)° =  90°

6m = 90 + 12  = 102

m = 102/6 = 17

Therefore the value of m = 17

The correct answer is option B.  17

Answer:

i think the answer is -33

Step-by-step explanation:

The drug is estimated to lower a typical patient's systolic blood pressure by at least -56.367 and at most -45.433 (using a 90% confidence level).

To estimate the reduction in systolic blood pressure with a 90% confidence level, we can construct a confidence interval using the sample mean and standard deviation. Since the sample size is 30 and the data is assumed to be normally distributed, we can use the t-distribution.

The formula for a confidence interval for the mean is:

CI = Mean ± t * (s / √n),

where mean is the sample mean, s is the sample standard deviation, n is the sample size, and t is the critical value from the t-distribution corresponding to the desired confidence level.

In this case, the sample mean (x) is 50.9, the sample standard deviation (s) is 18.7, and the sample size (n) is 30. Since we want a 90% confidence level, we need to find the critical value (t) with a degree of freedom of 29 (n-1) and a tail probability of 0.05 (1 - 0.90).

Using statistical tables or software, we find that the critical value is approximately 1.699.

Plugging in the values, we can calculate the confidence interval:

CI = 50.9 ± 1.699 * (18.7 / √30).

Calculating the interval, we get:

CI = 50.9 ± 9.968.

Simplifying, we have:

CI = (-58.868, -42.932).

Therefore, the drug is estimated to lower a typical patient's systolic blood pressure by at least -56.367 (rounded to three decimal places) and at most -45.433 (rounded to three decimal places) with a 90% confidence level.

y - z = -2

x + y - z = -4

Evaluate

x + y = 0

-2 - 2 = 0 --- False

This means that this system of equations do not have a solution of (-2,-2,-2)

Option 2:

Answer:

Quantity of milk = 60 x 2/3 litres = 40 litres.

Quantity of water in it = (60- 40) litres = 20 litres.

New ratio = 1 : 2

Let quantity of water to be added further be x litres.

Then, milk : water = 40 /20 + x

Now, 40 /20 + x = 1/2

20 + x = 80

x = 60.

The example of area is the amount of wallpaper for a wall in a bedroom.

Area is a measure of the two-dimensional space inside a closed shape, such as a rectangle, triangle, or circle. It is typically expressed in square units, such as square meters, square inches, or square feet. In this case, the amount of wallpaper needed to cover a wall in a bedroom is an example of area because it requires measuring the two-dimensional space of the wall in order to determine the amount of wallpaper needed. The wall can be measured by finding the length and width and multiplying the two measurements together to get the total area. The amount of wallpaper needed is then determined by dividing the total area of the wall by the area of a single roll of wallpaper.

The number of towels that can fit in a bathroom cabinet and the amount of ribbon used to decorate a room from one end to another are not examples of area. The number of towels that can fit in a cabinet is a measure of volume, while the amount of ribbon used to decorate a room is a measure of length.
