Answer:

B. 45°

Step-by-step explanation:

The angles of a triangle have to add up to 180°.

In this triangle C is given as 90°. That leaves 90° for the sum of the two others. Since the triangle is symmetrical, you can divide 90° by 2 to get to equal angles of 45°.

In the least-squares regression line equation, the slope is defined as the change in the response variable to unit change in the explanatory variable. So, option (a) is right one.

A regression line is a linear line that best fits the data, but this does not mean that the fit is good. In some cases, there can still a lot of variability. The slope of least-squares regression line is change in the response variable by a unit change in the explanatory variable. Because a regression line will only pass through all the data points if r = ± 1, the slope is defined as the predicted change in the response variable by a unit change in the explanatory variable. This line is always passes through the means points of the explanatory and response variables respectively. So, the correct option is option(a).

Considering the technological advancement of the cell phone, customers perceive its value to be around $800. In this scenario, the economic value created is $450.

We can solve this by,

Cost: The expenses incurred by a firm while producing goods or providing services are known as cost.

Product: The item that is produced, processed, or delivered for sale is known as a product.

Value: The economic value of a product is determined by how much it is valued in the marketplace, which is a function of how much people are willing to pay for it. In the given scenario,

          Talkalot Corp. Incurs a cost of $350 to produce one unit of a cell phone. The company's management has priced the product at $600 in the market. Considering the technological advancement of the cell phone, customers perceive its value to be around $800.

       As per the scenario, the value created is:

          The value created = Perceived value - Cost Value created

                                          = $800 - $350

          The value created = $450

  Therefore, the economic value created in this scenario is $450.

The solutions to the expressions using laws of exponents are;

The product rule of exponents states that "To multiply two expressions with the same base, add the exponents while keeping the base the same". Thus;

y² × y³ = y²⁺³

= y⁵

17) y^(3/7) × y^(1/4)

Applying product rule of exponents gives;

Therefore, the value of the integral ∫2^6 (5f(x))^2 dx is 900.

If the average value of the function f on the interval 2 ≤ x ≤ 6 is 3, we can express it mathematically as:

(1/(6 - 2)) ∫2^6 f(x) dx = 3

Simplifying this equation, we have:

(1/4) ∫2^6 f(x) dx = 3

Now, let's calculate the value of the integral ∫2^6 (5f(x))^2 dx:

∫2^6 (5f(x))^2 dx = 25 ∫2^6 (f(x))^2 dx

Since the average value of f on the interval 2 ≤ x ≤ 6 is 3, we can substitute it into the equation:

25 ∫2^6 (f(x))^2 dx = 25 * (4/1) * 3^2

Simplifying further, we get:

25 * (4/1) * 3^2 = 25 * 4 * 9 = 900

The theoretical probability for the 1 horned, 1 eyed,  flying, people eater purple is found to be 1/120.

Experimental Probability: Based on actual results rather than mathematical calculations, the experimental probability of an occurrence is the likelihood that the event will actually occur.

Theoretical Probability: Considering that the event is ideal, the theoretical chance that it will occur is the theoretically ideal probability of a specific result. The flaws in the system are not taken into consideration by theoretical probability.

Theoretical Probability = Number of favorable outcomes / Number of possible outcomes.

The linear approximation of ln(1.09) is approximately equal to 0.09 (rounded to two decimal places).

To use a linear approximation to estimate ln(1.09) and produce a small error, we will follow these steps:
Step 1: Choose a value of 'a' close to 1.09 for which the natural logarithm is easy to calculate. In this case, we can choose a = 1.
Step 2: Find the derivative of the natural logarithm function, which is f'(x) = 1/x.
Step 3: Evaluate the derivative at the chosen value of 'a'. In our case, f'(1) = 1/1 = 1.
Step 4: Use the linear approximation formula to estimate ln(1.09):
ln(1.09) ≈ ln(a) + f'(a) * (1.09 - a)
Step 5: Plug in the values of 'a' and f'(a) into the formula:
ln(1.09) ≈ ln(1) + 1 * (1.09 - 1)
Since ln(1) = 0, we have:
ln(1.09) ≈ 1 * (0.09) = 0.09

Answer:

PQ measures 36 units.

Step-by-step explanation:

Line RS bisects segment PQ at R. By the definition of a bisector:

\(\displaystyle PR = RQ\)

Hence:

We are given that RQ = x + 9 and RP = 2x, and we want to determine PQ.

Solve for x. Substitute:

\(\displaystyle (2x) = (x+9)\)

Hence:

\(\displaystyle x = 9\)

PQ is given by:

\(\displaystyle PQ = PR + RQ\)

Since PR = RQ:

\(\displaystyle PQ =2PR\)

Substitute and evaluate:

\(\displaystyle \begin{aligned} PQ &= 2PR \\ &= 2(2x) \\ &= 4x \\ &= 4(9) \\ &= 36 \end{aligned}\)

Hence, PQ measures 36 units.
