Answer:

42

Step-by-step explanation:

there are six sides, perimeter is just all the sides added together.

7+7+7+7+7+7=42

or 7*6=42

pls mark brainliest

Answer:

\(42\:\mathrm{cm}\)

Step-by-step explanation:

The perimeter of a polygon is equal to the sum of all the sides of the polygon. The polygon in the figure is a hexagon (polygon with six sides) and it is implied that all sides are equal. If each of the sides are 7 cm long, the perimeter must be \(7+7+7+7+7+7=7\cdot 6=\boxed{42\:\mathrm{cm}}\).

*It's good to note that the units for perimeter is the same unit as the sides are given as, because we're only adding the sides of the polygon.

A)The probability of exactly four buses arriving in the next 2 hours is\($P(X=4)=e^{\wedge}(-2)\left(2^{\wedge} 4 / 4 !\right)=0.090$\) ≈ 0.090.

B) The probability of at least two buses arriving in the next 2 hours is =0.865

C)  The probability of no buses arriving in the next 2 hours is =0.135

d) The probability that it will be between 30 and 90 minutes before the next bus arrives is ,0.185

a) Let \($X$\) be the number of buses that arrive in a 2-hour period. Since the time between arrivals of buses follows an exponential distribution with a mean of 60 minutes, the arrival rate λ is given by\($\lambda=1 / 60$\) 0 buses per minute.

Therefore, the number of buses that arrive in a 2-hour period is a Poisson distribution with parameter \(\mu=\lambda t=(1 / 60) \times 120=2$.\). Thus, X has a Poisson distribution with parameter μ = 2.

The probability of exactly four buses arriving in the next 2 hours is\($P(X=4)=e^{\wedge}(-2)\left(2^{\wedge} 4 / 4 !\right)=0.090$\) ≈ 0.090.

b) The probability of at least two buses arriving in the next 2 hours is

\($P(X \geq 2)=1-P(X=0)-P(X=1)=1-e^{\wedge}(-2)\left(2^{\wedge} 0 / 0 !\right)-e^{\wedge}(-2)\left(2^{\wedge} 1 / 1 !\right)=0.865$.\)

c) The probability of no buses arriving in the next 2 hours is

\(P(X=0)=$ $e^{\wedge}(-2)\left(2^{\wedge} 0 / 0 !\right)=0.135$\)

d) Let Y be the time between the first and second bus arrivals. Then Y follows an exponential distribution with a mean of 60 minutes. We want to find the probability that \($30 \leq Y \leq 90$\).

This is equivalent to finding \(P(Y \leq$ $90)-P(Y \leq 30)$,\), which is equal to F(90) - F(30), where F is the cumulative distribution function of the exponential distribution with \($\lambda=1 / 60$\)

Therefore, the probability that it will be between 30 and 90 minutes before the next bus arrives is\(F(90)-F(30)=\left(1-e^{\wedge}(-90 / 60)\right)-(1$ $\left.e^{\wedge}(-30 / 60)\right)=e^{\wedge}(-1.5)-e^{\wedge}(-0.5)=0.185$\)

The value of 6P6 is 720

The expression is given as:

6P6

This is calculated using:

\(^nP_r = \frac{n!}{(n - r)!}\)

So, we have:

\(^6P_6 = \frac{6!}{(6 - 6)!}\)

Evaluate the difference

\(^6P_6 = \frac{6!}{0!}\)

As a general rule;

0! = 1

So, we have:

\(^6P_6 = 6!\\\)

Expand

\(^6P_6 = 6 * 5 * 4 * 3 * 2 * 1\)

Evaluate

\(^6P_6 = 720\)

A 95% confidence interval for the proportion of all the registered voters who will vote for trump is  (0.25, 0.34).

What is a random sample?

A simple random sample is a subset of people chosen at random from a larger group, all of whom were chosen with the same probability. It is a method of choosing a sample at random.

Here, we have

Given, n = 400

x = 120

95% of confidence interval = z = 1.96

p = 120/400 = 0.3

Now by applying the confidence interval formula, we get

= 0.3 ± 1.96(√{0.3(1-0.3)}/400)

= 0.3 ± 0.0449

= (0.25, 0.34)

Hence,  a 95% confidence interval for the proportion of all the registered voters who will vote for trump is  (0.25, 0.34).

THERES UR ANSWER.........!!!!!!!!!!!!!

Lilly is travelling at a faster speed.

Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.

Speed is a scalar quantity as it only has magnitude and no direction.

Given that,

Distance travelled by Spencer = 4/5 mile

Time taken to travel the distance = 1 1/3 minutes = 4/3 minutes

Speed = Distance / Time = (4/5) / (4/3) = 3/5 = 0.60 mile per minute

Distance travelled by Lilly = 3/4 mile

Time taken to travel the distance = 1 1/8 minute = 9/8 minutes

Speed = (3/4) / (9/8) = 2/3 = 0.67 mile per minute

Hence Lilly is travelling at a greater speed of  0.67 mile per minute.

Step-by-step explanation:

It will take them 2 hours to do the whole task if they work together.

If one person can do a task in 3 hours and another person can do the same task in 6 hours, then we can calculate their individual rates of work as follows:

The first person can do 1/3 of the task per hour (since it takes them 3 hours to do the whole task).

The second person can do 1/6 of the task per hour (since it takes them 6 hours to do the whole task).

When they work together, their rates of work will add up, so their combined rate of work is:

1/3 + 1/6 = 1/2

This means that working together, they can do 1/2 of the task per hour. To find out how long it will take them to do the whole task, we can use the formula:

time = work ÷ rate of work

Since the whole task is 1 unit of work, and their combined rate of work is 1/2 units per hour, we can plug in these values to get:

time = 1 ÷ (1/2) = 2 hours

In the chi-square test for two-way tables, the null hypothesis (H0) typically claims that there is no association or relationship between the two categorical variables being analyzed. It states that any observed differences or associations between the variables in the two-way table are due to chance or random variation.

More specifically, the null hypothesis assumes that the observed frequencies in the two-way table are equal to the expected frequencies that would be observed if the variables were independent of each other. It suggests that any deviation from independence in the observed frequencies is purely due to sampling variability.

The alternative hypothesis (Ha), on the other hand, asserts that there is a significant association or relationship between the two variables, indicating that the observed frequencies differ from the expected frequencies in a way that is not likely to occur by chance alone.

The chi-square test is used to assess the evidence against the null hypothesis and determine whether the observed association in the two-way table is statistically significant.

Answer:

Kites are a special type of quadrilateral with two distinct pairs of consecutive sides the same length. ... Similarly, every kite is not a parallelogram, because the opposite sides of a kite are not necessarily parallel.

Answer:

No

Step-by-step explanation:

All parallelograms are not a kite.

A kite is a quadrilateral with two disjoint pairs ( no side is in both pairs ) of equal-length, adjacent ( sharing a vertex ) sides. A parallelogram also has two pairs of equal-length sides, however they must be opposite, as opposed to adjacent.

det(MBA) = det(diag(det A, det A, ..., det A)BA) = det(diag(det A, det A, ..., det A)) * det(BA) = det A * det(BA)

Bet AB = det BA, as required.

what is square matrix?

A square matrix is a matrix that has the same number of rows and columns. That is, a matrix A is square if A has dimensions n x n, where n is a positive integer.

To show that det AB = det BA, we can use the fact that for any invertible matrix M, we have det(MAB) = det(MBA) = det(M) * det(AB) = det(M) * det(BA). Therefore, it is sufficient to show that there exists an invertible matrix M such that det(MAB) = det(MBA).

Let M be the diagonal matrix with diagonal entries given by the determinant of A, i.e., M = diag(det A, det A, ..., det A). Then, we have:

det(MAB) = det(diag(det A, det A, ..., det A)AB) = det(diag(det A, det A, ..., det A)) * det(AB)

= det A * det(AB)

Similarly, we have:

det(MBA) = det(diag(det A, det A, ..., det A)BA) = det(diag(det A, det A, ..., det A)) * det(BA)

= det A * det(BA)

Thus, if M = $1.5 trillion, V = 7, and P = 1.05, the real output of the economy (Q) is $10 trillion.

The equation of exchange is an economic equation that relates the money supply (M) with the price level (P), the velocity of money (V), and the real output of the economy (Q). The equation is M x V = P x Q.

Using the given values of M = $1.5 trillion, V = 7, and P = 1.05, we can solve for Q by rearranging the equation as Q = M x V / P.

Plugging in the numbers, we get:

Q = ($1.5 trillion x 7) / 1.05 = $10 trillion

Therefore, if M = $1.5 trillion, V = 7, and P = 1.05, the real output of the economy (Q) is $10 trillion.

It's worth noting that the equation of exchange is a theoretical model and may not reflect actual economic conditions. In practice, changes in any one of the variables (M, V, P, or Q) can affect the others, and there may be other factors at play that influence the economy.

Nonetheless, the equation of exchange provides a useful framework for thinking about the relationship between the money supply, prices, and economic activity.

The optimal values of these parameters are:

a. β₁ = 0

b. β₂ = 0

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.

Therefore, the answers are: a. β₁ = 0 b. β₂ = 0

The weight distribution of newborn African lions may not necessarily follow a normal distribution, and the actual percentages can vary based on the specific data available.

To determine the percentage of newborn African lions that weigh less than 3 pounds and the percentage that weigh more than 3.8 pounds, we would need statistical data on the weight distribution of newborn African lions. Since we don't have that information, we cannot provide the exact percentages.

However, if we assume that the weights of newborn African lions follow a normal distribution, we can use the properties of the standard normal distribution to make an estimation.

For the percentage of newborn African lions weighing less than 3 pounds:

We would need to know the mean and standard deviation of the weight distribution to calculate the Z-score for a weight of 3 pounds and then find the corresponding percentage using a standard normal distribution table. Without this information, we cannot provide an accurate estimation.

For the percentage of newborn African lions weighing more than 3.8 pounds:

Similarly, we would need the mean and standard deviation of the weight distribution to calculate the Z-score for a weight of 3.8 pounds and find the corresponding percentage using a standard normal distribution table. Without the required information, we cannot provide a specific estimation.
