Given:

Lena rolled two number cubes and recorded the results.

To find:

The experimental probability that the sum of the next two numbers rolled is greater than 5.

Solution:

If two number cubes rolled, then the total possible outcomes are:

(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (21,1), (2,2), (2,3), (2,4), (2,5), (2,6),

(3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6),

(5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1), (6,2), (6,3), (6,4), (6,5), (6,6)

Total number of possible outcomes = 36

The possible cases in which the sum is less than or equal to 5 are (1,1), (1,2), (1,3), (1,4), (2,1), (2,2), (2,3), (3,1), (3,2), (4,1).

In 10 cases the sum is less than or equal to 5. So, the number of cases in which the sum is greater than 5 is:

\(36-10=26\)

So, the number of favorable outcomes = 26.

Now, the experimental probability that the sum of the next two numbers rolled is greater than 5 is:

\(P=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}\)

\(P=\dfrac{26}{36}\)

\(P=\dfrac{13}{18}\)

Therefore, the required probability is \(\dfrac{13}{18}\).

The x-intercepts of a quadratic function are the points where the function graph intersects the x-axis. To find the x-intercepts of the given quadratic function, we need to determine the values of x when the y-value (or the function value) is equal to 0.

From the given information, we can see that the quadratic function passes through the points (-2, 0) and (1, 0), which indicates that the function intersects the x-axis at x = -2 and x = 1. Therefore, the quadratic function x-intercepts are (-2, 0) and (1, 0).

The correct answers are (d) (-2, 0) and (1, 0).

False. Exponential smoothing with α = 0.2 and a moving average with n = 5 do not put the same weight on the actual value for the current period. Exponential smoothing and moving averages are two different forecasting techniques that use distinct weighting schemes.

Exponential smoothing uses a smoothing constant (α) to assign weights to past observations. With an α of 0.2, the weight of the current period's actual value is 20%, while the remaining 80% is distributed exponentially among previous values. As a result, the influence of older data decreases as we go further back in time.On the other hand, a moving average with n = 5 calculates the forecast by averaging the previous 5 periods' actual values. In this case, each of these 5 values receives an equal weight of 1/5 or 20%. Unlike exponential smoothing, the moving average method does not use a smoothing constant and does not exponentially decrease the weight of older data points.In summary, while both methods involve weighting schemes, exponential smoothing with α = 0.2 and a moving average with n = 5 do not put the same weight on the actual value for the current period.

To find the largest number of passengers in the tram, we need to calculate the maximum number of passengers who can go without a ticket.

Given that 12% of passengers go without a ticket, we can set up the following equation:

12% of x = 60

To solve for x, we can divide both sides of the equation by 0.12:

x = 60 / 0.12

x = 500

Therefore, the largest number of passengers in the tram, if it is not greater than 60, would be 500.

To find the largest number of passengers in the tram, we use the percentage given and set it equal to the number of passengers. By solving for x, we determine that the largest number of passengers in the tram is 500.

The largest number of passengers in the tram, if it is not greater than 60, is 500.

Part A: For which value(s) of x does f(x)=x^3/3+x^2+4x−10 have a tangent line of slope 3?

The derivative of f(x) is f'(x)=x^2+2x+4.

The tangent line to f(x) has a slope of 3 when f'(x)=3. This occurs when x^2+2x+4=3. Solving for x, we get x=-1 or x=-2.

Therefore, the values of x for which f(x) has a tangent line of slope 3 are -1 and -2.

Part B: For z(x)=f(x)h(x), please use the product rule to find z′(3), given f(3)=5,f′(3)=−2,h(3)=1,h′(3)=9.

The product rule states that the derivative of a product of two functions is the first function times the derivative of the second function, plus the second function times the derivative of the first function.

In this case, the first function is f(x) and the second function is h(x).

Therefore, z′(x)=f'(x)h(x)+f(x)h'(x).

f(3)=5,f′(3)=−2,h(3)=1,h′(3)=9, we get z′(3)=(−2)(1)+(5)(9)=43.

Therefore, z′(3)=43.

The measurement basis used when a reliable estimate of fair value is not available is the historical cost basis.

Historical cost basis refers to the original cost of acquiring an asset or incurring a liability. Under this basis, assets are recorded at the amount paid or the consideration given at the time of acquisition, and liabilities are recorded at the amount of consideration received in exchange for incurring the obligation.

This measurement basis is used when a reliable estimate of fair value is not available because fair value requires market prices or observable inputs, which may not be readily available in certain situations. In such cases, historical cost provides a more objective and verifiable measure of an asset's value.

For example, if a company purchases a building for $500,000, the historical cost of the building will be recorded as $500,000 on the balance sheet. Even if the fair value of the building increases or decreases over time, the historical cost will remain unchanged unless there are subsequent events that require a different measurement basis, such as impairment.

In summary, when a reliable estimate of fair value is not available, the historical cost basis is used as a measurement basis to record assets and liabilities at their original acquisition or incurrence cost.

Since none of the 13 classmates had been given math homework between the original survey and Kelly's second survey, the sum of the values in the second data set is the same as the sum of the values in the original data set. Therefore, the change in the means can be determined without calculating the mean of either data set by considering the number of data points in each set.

Since both data sets have the same number of data points, the change in the means will be zero. This is because the mean is calculated by dividing the sum of the values by the number of data points, and since the sum of the values is the same in both data sets, the means will also be the same.

In other words, if the mean of the first data set is x, then the sum of the values in the first data set is 13x (since there are 13 classmates), and the sum of the values in the second data set is also 13x (since none of the values have changed). Therefore, the mean of the second data set will also be x, and the change in the means will be zero.

The correct options are C and B:

Domain: {x| -5 ≤ x ≤ 4}

Range: {x| -3 ≤ y ≤ 3}

Remember that for a function f(x) = y the domain is the set of the inputs (set of the possible values of x) and the range is the set of the outputs (possible values of y).

To identify the domain we need to look at the horizontal axis. The leftmost value is x = -5, so that is the minimum of the domain.

The rightmost value is x = 4, so that is the maximum of the domain.

Also notice that we have two closed circles, meaning that these values belong to the domain, then:

D: {x| -5 ≤ x ≤ 4}

For the range, we look at the vertical axis.

The lowest value is y = -3, the largest one is y = 3, then the range is:

R: {x| -3 ≤ y ≤ 3}

Answer: g(x) is exponential because it grows by equal factors over equal intervals​

Step-by-step explanation:

By using  Fundamental Theorem of Calculus, we find the derivative of the function g(x) = In { sqrt( t + t^3)dt } limit from x to 0 is  ln(sqrt(x + x^3)).  The derivative of the function g(x) = { In (1+t^2) dt} where limit are from x to 1 is  ln(1 + x^2).

The Fundamental Theorem of Calculus, which states that if a function is defined as the definite integral of another function, then its derivative is equal to the integrand evaluated at the upper limit of integration.

So, applying this theorem, we have:

g'(x) = d/dx [∫x_0 ln(sqrt(t + t^3)) dt]

= ln(sqrt(x + x^3)) * d/dx (x) - ln(sqrt(0 + 0^3)) * d/dx (0)

= ln(sqrt(x + x^3))

Therefore, g'(x) = ln(sqrt(x + x^3)).

Using the Fundamental Theorem of Calculus, we have:

g'(x) = d/dx [∫1_x ln(1 + t^2) dt]

= ln(1 + x^2) * d/dx (x) - ln(1 + 1^2) * d/dx (1)

= ln(1 + x^2)

The CDF of Y evaluated at y = 0.72 is 0.1296.

Since X1 and X2 are independent and uniformly distributed over [0, 2], their joint density function is:

f(x1, x2) = 1/4, for 0 ≤ x1 ≤ 2 and 0 ≤ x2 ≤ 2

To find the CDF of Y, we can use the fact that:

Fy(y) = P(Y ≤ y) = P(max(X1, X2) ≤ y)

This event can be split into two cases:

X1 and X2 are both less than or equal to y:

In this case, Y will be less than or equal to y.

The probability of this occurring can be calculated using the joint density function:

P(X1 ≤ y, X2 ≤ y) = ∫0y ∫0y f(x1, x2) dx1 dx2

= ∫0y ∫0y 1/4 dx1 dx2

\(= (y/2)^2\)

\(= y^2/4\)

One of X1 or X2 is greater than y:

In this case, Y will be equal to the maximum of X1 and X2.

The probability of this occurring can be calculated as the complement of the probability that both X1 and X2 are less than or equal to y:

P(X1 > y or X2 > y) = 1 - P(X1 ≤ y, X2 ≤ y)

\(= 1 - y^2/4\)

Therefore, the CDF of Y is:

Fy(y) = P(Y ≤ y) = P(max(X1, X2) ≤ y)

= P(X1 ≤ y, X2 ≤ y) + P(X1 > y or X2 > y)

\(= y^2/4 + 1 - y^2/4\)

= 1, for y ≥ 2

\(= y^2/4,\)for 0 ≤ y ≤ 2

To find Fy(0.72), we simply substitute y = 0.72 into the expression for Fy(y):

Since X1 and X2 are uniformly distributed over [0, 2], their probability density functions (PDFs) are:

fX1(x) = fX2(x) = 1/2, for 0 <= x <= 2

To find the CDF of Y = max(X1, X2), we need to consider two cases:

1. If y <= 0, then Fy(y) = P(Y <= y) = 0

2. If 0 < y <= 2, then Fy(y) = P(Y <= y) = P(max(X1, X2) <= y)

We can find this probability by considering the complementary event, i.e., the probability that both X1 and X2 are less than or equal to y. Since X1 and X2 are independent, this probability is:

P(X1 <= y, X2 <= y) = P(X1 <= y) * P(X2 <= y) = (y/2) * (y/2) = y^2/4

Therefore, the CDF of Y is:

Fy(y) = P(Y <= y) =

0,          y <= 0

y^2/4,      0 < y <= 2

1,          y > 2

To find Fy(0.72), we substitute y = 0.72 into the CDF:

Fy(0.72) = 0.72^2/4 = 0.1296
