Answer:

Step-by-step explanation:

1). WXYZ is a rectangle,

  Properties of a rectangle,

  i). Opposite sides are equal and parallel.

  ii). All interior angles measure 90°.

  iii). Diagonals are equal in measure.

a). WY = ZX = 30

 Therefore, ZT = \(\frac{1}{2}(ZX)\)

                    \(ZT=15\)

b). WY = ZX = 45

c). Since, WY = ZX,

    (4b - 16) = (3b + 5)

    4b - 3b = 16 + 5

     b = 21

2). GOAT is a rhombus and m∠OGA = 35°,

    a). m∠TGA = m∠OGA = 35°

    b). m∠GXO = 90°

Step-by-step explanation:

The amount invested at a 6% interest rate is $14,000. Therefore, the amount invested at a 4% interest rate is 23,000 - 14,000 = $9,000.In conclusion, the investment made at a 6% annual interest rate is $14,000. The investment made at a 4% annual interest rate is $9,000.

Amount invested at 4% annual interest rate $9,000Let the investment made at 6% by then the investment made at 4% is (23,000 - x)As per the question, the annual return from 6% interest is:

0.06x

And the annual return from 4% interest is:

0.04(23,000 - x)

Adding them, we get:

0.06x + 0.04(23,000 - x)

= 1,200

Simplifying the above equation:

0.06x + 920 - 0.04x

= 1,200 0.02x

= 280 x

= 14,000

Therefore, the investment made at a 6% annual interest rate is $14,000.

The remaining investment, which is 23,000 - 14,000

= $9,000 is made at a 4% annual interest rate.

Therefore, the amount invested at a 4% interest rate is $9,000.

When an executive invests $23,000, some at 6% and the rest at 4% annual interest, the return on his annual investment is $1,200.

Let's assume that the investment at 6% is x dollars, which invests 4% (23,000 - x) dollars. Based on the given information, the annual return from 6% interest is 0.06x.

Similarly, the annual return from 4% interest is 0.04(23,000 - x).

Therefore, the equation for annual investment returns is:

0.06x + 0.04(23,000 - x) = 1,200

Simplifying the equation:

0.06x + 920 - 0.04x

= 1,2000.02x

= 280x

= 14,000

The amount invested at a 6% interest rate is $14,000. Therefore, the amount invested at a 4% interest rate is 23,000 - 14,000 = $9,000.In conclusion, the investment made at a 6% annual interest rate is $14,000. The investment made at a 4% annual interest rate is $9,000.

Answer:

A

Step-by-step explanation:

The function that has a well-defined inverse is b. : → (x) = 2x - 5.

To explain why this function has a well-defined inverse, we need to consider the conditions for a function to have an inverse.

For a function to have an inverse, each input value (x) must have a unique output value (y), and each output value must have a unique corresponding input value. In other words, the function must be one-to-one, with no two different input values producing the same output value.

In the case of function b. : → (x) = 2x - 5, it is a linear function with a constant slope of 2. This means that for every different input value (x), we get a unique output value (y) through the formula 2x - 5.

Moreover, the fact that the coefficient of x is non-zero (2 in this case) ensures that no two different input values can produce the same output value. This guarantees the one-to-one nature of the function.

To find the inverse of b(x), we can follow these steps:

1. Replace the function notation with the variable y: x = 2y - 5.

2. Solve for y: x + 5 = 2y, y = (x + 5)/2.

3. Replace y with the inverse function notation: b^(-1)(x) = (x + 5)/2.

Therefore, the function b(x) = 2x - 5 has a well-defined inverse given by b^(-1)(x) = (x + 5)/2, satisfying the conditions for a function to have an inverse.

For a continuous random variable like X, the probability of waiting exactly 6 minutes (or any specific time) is always 0, as there are infinitely many possible values within the distribution.

For the second part of your question, since X is uniformly distributed between 4 and 14, the probability of X being between two specific ranges can be calculated by finding the lengths of those ranges divided by the length of the overall distribution.

For the range of 5 to 7, the length is (7 - 5) = 2.
For the range of 8 to 12, the length is (12 - 8) = 4.
The total length of the distribution is (14 - 4) = 10.

So the probability of X being in either range is (2 + 4) / 10 = 6 / 10 = 0.6, or 60% when rounded to 2 decimal places.

For the first question, since the continuous random variable x is uniformly distributed from 2 to 10 minutes, the probability that a randomly chosen shopper will wait in line for exactly 6 minutes is:

P(x = 6) = 1/(10-2) = 1/8 = 0.125

Therefore, the probability that a randomly chosen shopper will wait in line for exactly 6 minutes is 0.125.

For the second question, we need to find the probability that X is either between 5 and 7, or between 8 and 12. Since X is uniformly distributed between 4 and 14, we can find the probabilities of each interval separately and then add them up.

P(5 ≤ X ≤ 7) = (7-5)/(14-4) = 2/10 = 0.2

P(8 ≤ X ≤ 12) = (12-8)/(14-4) = 4/10 = 0.4

Therefore, the probability that X is either between 5 and 7, or between 8 and 12 is:

P(5 ≤ X ≤ 7 or 8 ≤ X ≤ 12) = P(5 ≤ X ≤ 7) + P(8 ≤ X ≤ 12) = 0.2 + 0.4 = 0.6

Therefore, the probability that X is either between 5 and 7, or between 8 and 12 is 0.6.

The linear regression y = β1 + β2x + e, assuming that the sum of squared errors (SSE) takes the following form:

SSE = 382 + 681 + 382 + 18β1β2

Derive the partial derivatives of SSE with respect to β1 and β2 and solve the optimal values of these parameters.

Given that SSE = 382 + 681 + 382 + 18β1β2 ∂SSE/∂β1 = 0 ∂SSE/∂β2 = 0

Now, we need to find the partial derivative of SSE with respect to β1.

∂SSE/∂β1 = 0 + 0 + 0 + 18β2 ⇒ 18β2 = 0 ⇒ β2 = 0

Therefore, we obtain the optimal value of β2 as 0.

Now, we need to find the partial derivative of SSE with respect to β2. ∂SSE/∂β2 = 0 + 0 + 0 + 18β1 ⇒ 18β1 = 0 ⇒ β1 = 0

Therefore, we obtain the optimal value of β1 as 0. Hence, the partial derivative of SSE with respect to β1 is 18β2 and the partial derivative of SSE with respect to β2 is 18β1.

Thus, the optimal values of β1 and β2 are 0 and 0, respectively.

Answer:

Let's name the angle right close to 51 as c.

c = 180°-51° since angles on a straight line is equal to 180°.

so c= 129°

so x = 129° since it corresponds to c

Answer:

Step-by-step explanation:

Notice that the line that the variable x is on is equal to 180 degrees. Because the angle that it is next to is equal to 51 degrees, you subtract 180 from 51:

180-51=129

The final answer to this problem is 129 degrees.
