The statement that, to be conservative,  an under-estimate should be used, is True.

A conservative estimate is a prediction or projection that is intentionally lower than what is expected or believed to be the actual outcome. This type of estimate is often used in financial planning or decision-making in order to be more cautious and avoid potential risks or disappointments.

Conservative estimates are based on the idea that it is better to be overly cautious and prepare for the worst-case scenario than to be overly optimistic and potentially be caught off guard.

This means that if McKyla wants a conservative budget, the wages should be put at the lower amount of $ 2, 400.

1. The center of dilation is vertex A, as it is the common vertex for both triangles.

2. The original triangle is the triangle ABC, while the dilated triangle is triangle AED, as the side lengths of triangle AED are the side lengths of triangle ABC multiplied by the scale factor.

A dilation happens when the coordinates of the vertices of an image are multiplied by the scale factor, changing the side lengths of a figure.

For this problem, the scale factor of the dilation is given as follows:

k = 1/2.

Meaning that the side lengths of the dilated triangle are half the side lengths of the original triangle, which is the reason for which ABC is the original triangle while AED is the dilated triangle.

As the vertex A is a common vertex to both triangles, it represents the center of dilation for this problem.

The probability that the product of any two distinct members of the set is a multiple of 196 is 0.2857.

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event will not occur and 1 indicating that the event will definitely occur.

If two distinct members of the set { 2, 4, 12, 14, 21, 28, 98 } are randomly selected and multiplied, then the total number of possible outcomes is:

7C2 = 21

Counting all the possible pairs of numbers whose product is a multiple of 196, there are 6 possible ways.

(98 x 4) , (98 x 12) , (98 x 14) , (98 x 28) , (28 x 14) , (28 x 21)

The required x-intercept of line 4x + 2y ≥ 14 is (3.5, 0).

The x-intercept is defined as an intercept that is located at the x-axis of the plane, is the location or coordinate from where the line crosses.

The x-intercept of a line is the point at which the line crosses the x-axis.

To determine the x-intercept of line 4x + 2y ≥ 14, we need to set y equal to 0 and solve for x.

When y = 0, the inequality becomes 4x ≥ 14.

Dividing both sides by 4 gives x ≥ 14/4, or x ≥ 3.5.

Graphical solutions of a system of equations are way of finding the intersection points of all the equations given.

A system with two or more than two equations has a solution only when they have a common intersection point.

By observing the graph we conclude the two companies will cost the same if 130 T-shirts are purchased as their individual graphs intersect each other.

Where the above scenario is given, the probability:  P(A, A) if two cards are randomly selected with replacement is one-ninth or 1/9 (Option B)

Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.

Thus,

P(E) = Number of required outcomes / Total number of possible outcomes

Where P(E) is the Probability of the Expected value.

The possible outcomes are the spelling of the word ADD,

The probabilities are 1/3, 1/3, 1/3 respectively.

Given data,

F(s): L{(t-1)u(t-1)}

Where L is the Laplace transformation

Laplace transform is the integral transform of the given derivative function with real variable t to convert into a complex function with variable s. For t ≥ 0, let f(t) be given and assume the function satisfies certain conditions to be stated later on.

F(s) = [tex]\int\limits^\alpha _0 {f(t)} e^{-st} t^{l} \,[/tex]

Where,

s = σ + [tex]iw[/tex]

F(s) = Laplace transform

s = complex number

t = real number >=0

[tex]t^{l}[/tex] = first derivative of the function f(t)

The Laplace transform reduces a linear differential equation to an algebraic equation, which can then be solved by the formal rules of algebra.

So,

We can write,

F(s): L{(t-1)u(t-1)}

F(s) = [tex]\int\limits^\alpha _0 {f(t)} e^{-st} t^{l} \,[/tex]

F(s) = [tex]\int\limits^\alpha _0 {(t-1)u(t-1)} e^{-st} \, dt[/tex]

F(s) =  [tex]e^{-s} (\frac{1}{s^{2} } )[/tex]

F(s) = [tex]\frac{1}{s^{2} } e^{-s}[/tex]

Using 3 different methods, we can find that YZ = 25m

Method 1:

For a given triangle rectangle with a known angle θ and a hypotenuse H, we can write the trigonometric relations -

sin(θ) = (opposite side)/Hypotenuse

cos(θ) = (adjacent side)/Hypotenuse

tan(θ) = (opposite side)/(adjacent side)

Now, in the given image we can see that:

θ = 30°

H = 50m

XY = adjacent side

YZ = opposite side.

We want to find YZ, so with the known things, we can use the first relation:

sin(30°) = YZ/50m

YZ = sin(30°) * 50m

YZ = 1/2 *50m

YZ = 25m

Method 2:

We know that the sum of the measure of all the internal angles of a triangle is always equal to 180°.

In a right-angled triangle, we have an angle equal to 90°.

Then we can write -

Z + 90° + 30° = 180°

Z = 180° - 90° - 30°

Z = 60°

From this angle, the side YZ is the adjacent side, then we can use the second trigonometric relation:

cos (60°) = YZ/50m

YZ = cos(60°) * 50m

YZ = 1/2 *50m

YZ = 25m

Method 3:

With the same angle of 60° we could find side XY, the opposite side as follows:

sin(60°) = XY/50m

XY = sin(60°) * 50m

XY = √3/2 *50m

XY = 25m

Now that we know one of the sides, we can use the last trigonometric relation-

tan(60°) = XY/YZ

tan(60°) = 43.3m/YZ

YZ =  43.3m/tan(60°)

YZ = 25m

In statistics, a hypothesis test is the performance of a test on an assumption made about a population parameter.

The possible data in the question, obtained from a similar online question, using MS Excel, indicates;

The mean of the Starnes GPA ≈ 3.212867

The standard deviation of Starnes GPA ≈ 0.364249

Mean of McGrail GPA ≈ 3.134722

The standard deviation of McGrail's GPA ≈ 0.357995

The null hypothesis is H₀: μ₁ - μ₂ = 0

The alternative hypothesis is Hₐ: μ₁ - μ₂ ≠ 0

The test statistic is found using the following formula;

[tex]t_0 = \dfrac{(\overline{x_1} - \overline{x_2})-(\overline{\mu_1}-\overline{\mu_2})}{\sqrt{\dfrac{s_1^2}{n_1}+\dfrac{s_2^2}{n_2} } }[/tex]

The decision rule is obtained with α = 0.05 and the null hypothesis is rejected t₀ ≤ -1.96 or t₀ ≥ 1.96

Therefore, we get;

[tex]t_0 = \dfrac{(3.212867 - 3.134722)-0}{\sqrt{\dfrac{0.364249^2}{15}+\dfrac{0.357995^2}{18} } } \approx 0.618[/tex]

The parameter for the degrees of freedom is 15 - 1 = 14

The critical value obtained from the t-table, at t.₉₅ is 1.761 which is larger than 0.618, therefore, we fail to reject the null hypothesis, and the evidence is insufficient to suggest that there is a difference in the average score of the two AP Statistics classes.

Taking the variance to be the same, we get;

[tex]S_p^2= \dfrac{(n_1-1)\cdot s_1^2+(n_2-1)\cdot s_2^2}{n_1+n_2-2}[/tex]

Therefore;

[tex]S_p^2= \dfrac{(15-1)\times 0.364249^2+(18-1)\times 0.357995^2}{15+18-2}\approx 0.1302[/tex]

[tex]t_0 = \dfrac{(\overline{x_1} - \overline{x_2})-(\overline{\mu_1}-\overline{\mu_2})}{\sqrt{s_p^2 \times\left(\dfrac{1}{n_1}+\dfrac{1}{n_2} }\right) }[/tex]

[tex]t_0 = \dfrac{(3.212867 - 3.134722)-0}{\sqrt{0.1302\times \left(\dfrac{1}{15}+\dfrac{1}{18} }\right) } \approx 0.6195[/tex]

df = 15 + 18 - 2 = 31

From the t-table, the critical value is about 1.697, which is larger than 0.6195, therefore, the null hypothesis cannot be rejected and the evidence available is not enough to suggest that there is a difference between the grade point averages of Mr. Starnes and Ms. McGrail AP Statistics classes and Mr. Starnes did not stack the class
