Answer:
Height = 10 in.
Step-by-step explanation:
Area of a trapezoid = ½(a + b)*h
Where,
a = 6.7 in.
b = 7.3 in.
h = height = ??
Area = 70 in.²
Plug in the values
70 = ½(6.7 + 7.3)*h
70*2 = 14h
140 = 14h
Divide both sides by 14
140/14 = h
h = 10 in.

(a) i and ii (b) 1 and iii (c) ii and iii (d) i, il, and ii (e) none of these are true
Influential scores, indicated by large residuals, have a significant impact on the regression line when removed from the data. These points, characterized by extreme x or y-values, can alter the slope and intercept of the regression line, emphasizing their importance in regression analysis.
The correct statements about influential scores are i and ii.
i. Influential scores have large residuals because they have a strong effect on the regression line. This means that if we remove an influential score from the data, it will significantly change the slope and intercept of the regression line.
ii. Removal of an influential score sharply affects the regression line because influential scores have a large impact on the regression line. If we remove an influential score, it will significantly change the slope and intercept of the regression line.
iii. This statement is not true. An x-value that is an outlier in the x-variable may be indicative of a point being influential, but a y-value that is an outlier in the y-variable can also be indicative of a point being influential.

.A system consists of five identical components connected in series as shown:
A system consists of five identical components con
As soon as one components fails, the entire system will fail. Suppose each component has a lifetime that is exponentially distributed with ? = 0.01 and that components fail independently of one another. Define eventsAi = {ith component lasts at least t hours}, i = 1, . . . , 5, so that the Ais are independent events. Let X = the time at which the system fails
The time at which the system fails, denoted by X, is the minimum of the lifetimes of the five components.
In this system, each component has a lifetime that follows an exponential distribution with a parameter λ = 0.01. The exponential distribution is commonly used to model the time until an event occurs in a system with a constant failure rate.
The probability that a component lasts at least t hours is given by P(Ai) = e^(-λt), where Ai is the event that the ith component lasts at least t hours.
Since the components fail independently of one another, the probability that all five components last at least t hours is the product of their individual probabilities: P(A1 ∩ A2 ∩ A3 ∩ A4 ∩ A5) = e^(-λt)^5 = e^(-5λt).
Now, let X be the time at which the system fails, which is the minimum of the lifetimes of the five components. Since X is the minimum, we can write X = min(T1, T2, T3, T4, T5), where Ti represents the lifetime of the ith component.
The probability distribution of X can be obtained by considering the complement event. The complement of X > t is that all five components last at least t hours, which is P(X > t) = P(A1 ∩ A2 ∩ A3 ∩ A4 ∩ A5) = e^(-5λt).
Therefore, the time at which the system fails, X, follows an exponential distribution with a parameter of 5λ = 0.05. This means that the system has a constant failure rate of 0.05 and the probability density function (pdf) of X is given by f(x) = 0.05 * e^(-0.05x).

(2x + 24)°
142°
(1 point)
Answer:
59
Step-by-step explanation:
The angle measures (2x + 24) and 142 are equal to each other since we are looking at a line being cut by a "transversal" So, set them to equal each other like so:
2x + 24 = 142
Now solve:
2x + 24 = 142
2x = 118
x = 59
Answer:
a) x = 59
Step-by-step explanation:
Now we have to,
→ find the required value of x.
We know that,
→ opposite angles are always equal.
Then the value of x will be,
→ 2x + 24° = 142°
→ 2x = 142° - 24°
→ 2x = 118°
→ x = 118/2
→ [ x = 59 ]
Hence, the value of x is 59.

aaron and baron are playing a game with coins. suppose that aaron has a coin with probability of getting heads and baron has a coin with probability of getting heads. in each round, aaron and baron independently flip their coins at the same time. if no one gets heads, they play again. the game ends when either aaron or baron gets heads. the winner is the first one to get heads. the game may end in a tie if they both get heads in the same round. let denote the number of rounds aaron and baron play. what distribution is r?
R follows a geometric distribution with parameter p, the probability of either aaron or baron getting heads in a given round.
The number of rounds r follows a geometric distribution with parameter p, the probability of either aaron or baron getting heads in a given round. This is because the probability of r rounds occurring before either aaron or baron gets heads is equal to p^r, where p is the probability of either one of them getting heads in a given round. The probability of a tie is equal to p^2.
The geometric distribution is a discrete probability distribution that models the number of successes that occur in a sequence of independent Bernoulli trials before a specified (non-random) number of failures occur. The geometric distribution is the only discrete memoryless probability distribution, meaning that the probability of success in the next trial is independent of the previous outcomes. In the case of aaron and baron's coin game, the geometric distribution can be used to model the number of rounds that will occur before either aaron or baron gets heads. The probability of a given number of rounds occurring before either aaron or baron gets heads is equal to p^r, where p is the probability of either one of them getting heads in a given round. The probability of a tie is equal to p^2. Therefore, the number of rounds r follows a geometric distribution with parameter p.

Find the surface area of the regular pyramid.

Find the surface area of the regular pyramid.
A square pyramid. The length of the base is 4 and one-half meters. The height of each triangular face is 4 meters.
The surface area of the given square pyramid is 56.25 square meters.
To find the surface area of a regular square pyramid, we need to calculate the areas of its individual components and sum them up.
First, let's find the area of the base. The base of the square pyramid is a square, so the area of the base is given by:
Area of the base = side length^2
Given that the length of the base is 4 and one-half meters (or 4.5 meters), we can calculate the area of the base as:
Area of the base = (4.5 meters)^2 = 20.25 square meters
Next, let's find the area of each triangular face. Since the pyramid is regular, all the triangular faces are congruent.
The area of a triangle can be calculated using the formula:
Area of a triangle = (1/2) × base × height
In this case, the base length of each triangular face is equal to the length of the base of the pyramid, which is 4.5 meters. The height of each triangular face is given as 4 meters.
Thus, the area of each triangular face is:
Area of each triangular face = (1/2) × (4.5 meters) × (4 meters) = 9 square meters
Since there are four triangular faces in a square pyramid, the total area of the triangular faces is:
Total area of the triangular faces = 4 × (Area of each triangular face) = 4 × 9 square meters = 36 square meters
Finally, we can find the surface area of the square pyramid by adding the area of the base and the total area of the triangular faces:
Surface area of the square pyramid = Area of the base + Total area of the triangular faces = 20.25 square meters + 36 square meters = 56.25 square meters
Therefore, the surface area of the given square pyramid is 56.25 square meters.

Two friends, Francisco and Zoe, had just bought their first cars. Zoe uses 14 gallons of gas to drive 390.6 miles in her car. The graph below represents the number of miles, y, that Francisco can drive his car for every x gallon of gas.
Using linear function to solve this problem, for every 1 gallon of gas, Francisco travelled 27.9 miles
Linear FunctionA linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2. A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. where m is slope of the line and b is the y - intercept
We can use the data given in writing out our equation
y = Number miles coveredx = number of gallon390.6 = 14x
If 14 gallons = 390.6 miles
1 gallon = x miles
x = 390.6 / 14
x = 27.9 miles

The expected return on MSFT next year is 12% with a standard deviation of 20%. The expected return on AAPL next year is 24% with a standard deviation of 30%. If James makes equal investments in MSFT and AAPL, what is the expected return on his portfolio. 3. Siebling Manufacturing Company's common stock has a beta of .8. If the expected risk-free return is 2% and the market offers a premium of 8% over the risk-free rate, what is the expected return on Siebling's common stock
The expected return on James's portfolio is 18%.
The expected return on Siebling Manufacturing Company's common stock is 8.4%.
To calculate the expected return on James's portfolio, we need to take the weighted average of the expected returns of MSFT and AAPL based on their respective investments.
Let's assume James invests x% in MSFT and (100 - x)% in AAPL.
The expected return on James's portfolio can be calculated as:
Expected Return = (x * Expected Return of MSFT) + ((100 - x) * Expected Return of AAPL)
Substituting the given values:
Expected Return = (x * 12%) + ((100 - x) * 24%)
To find the value of x that makes James's investments equal, we set the weights equal:
x = 100 - x
Solving this equation gives us x = 50.
Now we can substitute this value back into the expected return equation:
Expected Return = (50% * 12%) + (50% * 24%)
Expected Return = 6% + 12%
Expected Return = 18%
Therefore, the expected return on James's portfolio is 18%.
To calculate the expected return on Siebling Manufacturing Company's common stock, we can use the Capital Asset Pricing Model (CAPM).
The CAPM formula is:
Expected Return = Risk-Free Rate + Beta * Market Premium
Risk-Free Rate = 2%
Market Premium = 8%
Beta = 0.8
Expected Return = 2% + 0.8 * 8%
Expected Return = 2% + 6.4%
Expected Return = 8.4%
Therefore, the expected return on Siebling Manufacturing Company's common stock is 8.4%.

A baker is building a rectangular solid box from cardboard to be able to safely deliver a birthday cake. The baker wants the volume of the delivery box to be 360 cubic inches. If the width of the delivery box is 3 inches longer than the length and the height is 4 inches longer than the length, what must the length of the delivery box be?
2 inches
5 inches
8 inches
9 inches
Answer:
5
Step-by-step explanation:
Solution is 8 in
Let´s call dimensions of the box
x the length of the boxy the width of the box andh the height of the boxAccording to the problem statement
y = x + 3 and h = 4 in
The volume of the box is:
V = x×y×h V = 360 in³
Then V = x × ( x + 3 ) × 4 ( by substitution of y as a function of x )
360 = x × ( x + 3 ) × 4
Simplifying by 4
90 = x × ( x + 3 )
90 = x² + 3x
We got a second degree equation, solving for x
x² + 3×x - 90 = 0
x₁,₂ = ( -3 ± √ (3)² + 4×90 )/2 ⇒ x₁,₂ = ( - 3 ± 19,21 )/2
x₁ ⇒ is a negative value x = - 11,1 so we dismiss such solution
x₂ = 16.21/2
x₂ = 8.1 in
rounding to the nearest integer number we get the value for the length f the box
x₂ = 8 in ⇒ x = 8 in
