To determine if L1 and L2 are parallel, skew or intersecting, we need to compare their directional vectors. The directional vector for L1 is <2,4,-3> and the directional vector for L2 is <1,3,-2>.
To see if they are parallel, we can check if one is a scalar multiple of the other. We can write the directional vectors as <2,4,-3> = 2<1,2,-3> and <1,3,-2> = 1<1,3,-2>. Since they are not equal to each other, but one is a scalar multiple of the other, L1 and L2 are parallel.
To find the point of intersection, we can set the parametric equations for L1 and L2 equal to each other and solve for t.
From L1, we have:
x-4/2 = y+5/4 = z-1/-3 = t
From L2, we have:
x-2/1 = y+1/3 = z/-2 = t
Setting these equal to each other, we get:
(2t-4)/2 = (4t+5)/4 = (-3t-1)/-3 = t
Solving for t, we get:
t = 1
Substituting t=1 into any of the parametric equations, we can find the point of intersection:
From L1:
x = 2(1) + 4 = 6
y = 4(1) - 5 = -1
z = -3(1) + 1 = -2
Therefore, L1 and L2 are parallel and intersect at the point (6,-1,-2).

Your math teacher instructed you to draw a square with 16 cm perimeter, she then asked you to connect the midpoints of its side by line segment to form another square. If this action will continue for each new square, what is the perimeter of the 5th square?
We want to find the perimeter of the fifth square in the given sequence.
The perimeter of the fifth square is 1cm.
Let's see how to get that:
The perimeter of the first square is 16cm.
Remember that the perimeter of a square of side length S is:
P = 4*S
Then the side length of the first square is given by:
16cm = 4*S
16cm/4 = S = 4cm
Then she connects the midpoints of the sides to form another square (actually four equal squares).
The midpoint would be at half of the side length of the square, then the side length of the new squares is 4cm/2 = 2cm.
For the third square, the side length is divided by two again, to get 2cm/2 = 1cm
For the fourth square this happens again: 1cm/2 = 0.5cm
For the fift square this happens again: 0.5cm/2 = 0.25cm
Then we have a square of side length equal to 0.25cm, the perimeter will be:
p' = 4*0.25cm = 1cm
The perimeter of the fifth square is 1cm.

Student's t test for correlated groups really reduces to _________.
a.
the sign test
b.
Student's t test for single samples using difference scores
c.
Students t test for independent groups
d.
none of the above
Answer:
Step-by-step explanation:
Student's t test for correlated groups reduces to Student's t test for single samples using difference scores. Therefore, the correct answer is (b).
In a t test for correlated groups (also known as paired-samples or dependent-samples t test), the same group of participants is measured twice, under two different conditions or at two different times. The difference between the two measurements for each participant is calculated and used as the sample data. The t test for correlated groups compares the mean difference score to zero to determine if there is a significant difference between the two conditions or times.
This can be seen as equivalent to a t test for single samples using difference scores, where the mean difference score is compared to a known or hypothesized value of the population mean difference. In fact, the formula for calculating the t statistic is the same in both cases.

Step-by-step explanation:
4 - \(\frac{1}{12}\) g - 2 = \(\frac{3}{2}\) g + 1 - \(\frac{5}{6}\) g
multiply through by 12 ( the LCM of 12, 2 and 6 ) to clear the fractions
48 - g - 24 = 18g + 12 - 10g
- g + 24 = 8g + 12 ( subtract 8g from both sides )
- 9g + 24 = 12 ( subtract 24 from both sides )
- 9g = - 12 ( divide both sides by - 9 )

If the contribution margin from the order is greater than the additional fixed expenses, accepting the special order can result in an increase in operating income.
When evaluating a special sales order, the first step is to calculate the revenue from the order. This is typically based on the selling price and the quantity of units to be sold. Then, the variable expenses directly associated with fulfilling the order, such as direct materials, direct labor, and variable manufacturing overhead, are deducted from the revenue to determine the contribution margin.
Next, the additional fixed expenses that would be incurred if the special order is accepted need to be considered. These expenses are typically costs that are directly related to the production or fulfillment of the order and are not already included in the existing fixed expenses.
To assess the impact of the special order on operating income, the increase (or decrease) in operating income is calculated by subtracting the additional fixed expenses from the contribution margin. If the result is positive, it indicates that accepting the special order would lead to an increase in operating income.
In the given scenario, it is mentioned that Cotton has excess capacity to manufacture the special order. If the incremental analysis shows that the special order would result in a positive increase in operating income, it would be beneficial for Cotton to accept the special sales order.

Find all values of k, if any, that satisfy the equation.
[1 1 0] [k] [k 1 1] [1 0 2] [1] = 0
[0 2 -3] [1]
Expanding the matrix multiplication, we have k + 1 + 0 = 0, k + 2 = 2, 3 = -3, and k + 5 = 0. However, the equation 3 = -3 has no solution.
Let's calculate the matrix multiplication on the left-hand side of the equation. Expanding the multiplication, we obtain:
[k + 1 + 0] [k + 0 + 2] [1] = [0 2 -3]
[1 + 0 + 2] [k + 1 + 4] [1]
Simplifying, we have:
[k + 1] [k + 2] [1] = [0 2 -3]
[3] [k + 5] [1]
To determine if there are values of k that satisfy the equation, we compare the corresponding entries on both sides. From the first row, we have k + 1 = 0 and k + 2 = 2. Solving these equations gives k = -1 and k = 0, respectively.
However, when we consider the second row, we have 3 = -3, which has no solution. Therefore, there are no values of k that satisfy the given equation. This means that the equation [1 1 0] [k] [k 1 1] [1 0 2] [1] = 0 [0 2 -3] [1] has no solution.

A boat has a speed of 11 mph in still water. If the boat takes the same time to go 40 miles upstream as it takes to go 70 miles downstream, what is the speed of the current
To solve this problem, let's assume the speed of the current is "x" mph. When the boat is traveling upstream (against the current), its effective speed is reduced by the speed of the current. Therefore, the speed of the boat relative to the water is 11 - x mph.
When the boat is traveling downstream (with the current), its effective speed is increased by the speed of the current. Therefore, the speed of the boat relative to the water is 11 + x mph.
Now, let's calculate the time taken for each leg of the journey:
Time taken to go 40 miles upstream = Distance / Speed
Time taken to go 40 miles upstream = 40 / (11 - x) hours
Time taken to go 70 miles downstream = Distance / Speed
Time taken to go 70 miles downstream = 70 / (11 + x) hours
According to the problem, these times are equal. So, we can set up the equation:
40 / (11 - x) = 70 / (11 + x)
To solve this equation, we can cross-multiply:
40 * (11 + x) = 70 * (11 - x)
440 + 40x = 770 - 70x
Now, let's solve for x:
110x = 330
x = 3
Therefore, the speed of the current is 3 mph.

Answer:
t = 12
Step-by-step explanation:
2t+6=3t-6
Subtract 2t from each side
2t-2t+6=3t-2t-6
6 =t -6
Add 6 to each side
6+6 = t-6+6
12 = t
Answer:
t = 12
Step-by-step explanation:
Goal : move all the "t" terms to one side and all the constants to the other side.
2t+6=3t-6 (subtract 6 from both sides)
2t = 3t - 6 - 6
2t = 3t -12 (subtract 3t from both sides)
2t - 3t = -12
-t = -12 (multiply both sides by -1)

Suppose you invest $850 in a certificate of deposit that is promised to make you 1% interest if you keep the money in the account for 16 months. How much money should be in the account after the 16 months has elapsed?
After 16 months, the amount of money in the account should be approximately $861.33.
To calculate the total amount in the account after 16 months with a 1% interest rate, we need to apply the formula for compound interest: A = P(1 + r)^t, where A is the final amount, P is the principal amount, r is the interest rate, and t is the time period.
In this case, you invest $850 as the principal amount with an interest rate of 1% (or 0.01 as a decimal). The money will be kept in the account for 16 months, so t = 16/12 = 4/3 years (since there are 12 months in a year).
Substituting the given values into the compound interest formula, we have:
A = $850(1 + 0.01)^(4/3)
Simplifying the exponent:
A = $850(1.01)^(4/3)
Evaluating the exponent:
A = $850(1.01005)
Multiplying:
A ≈ $861.33
after 16 months, the amount of money in the account should be approximately $861.33.
