Answer:

Well, the answer is based on how many beans there are in total

Step-by-step explanation:

If there are, for instance, 36 beans and four boxes, each box will have nine beans. You'll have to divide the total number of beans and the number of boxes. You'll find the solution with this method. Otherwise, if there are no details on how many beans and boxes there are, the answer is unclear.

The height of the building to the nearest foot is 186 feet.

The situation form two similar right triangle.

Similar triangle are not necessarily the same size. There corresponding angles are the same. The corresponding sides are a ratio. Therefore, we will establish a ratio of the triangles.

x = height of the building

Using similar triangle ratio:

5 / x = 4.5 / 167

cross multiply

167 × 5 = 4.5x

4.5x = 835

x = 835 / 4.5

x = 185.555555556

x = 186 ft.

Using the above property, the expression of the problem is simplified as follows:

The characteristic equation for the recurrence relation is (r-1)(r-4)=0. This equation has two roots:

r=1 and r=4. Therefore, the general form of the solution is an = a1(1)n + a2(4)n. Therefore, the correct answer is A.

The recurrence relation can be written as an = an-1 + 4an-2. Substituting the general form of the solution into th

is equation, we get a1(1)n + a2(4)n = a1(1)n-1 + a2(4)n-1 + 4a1(1)n-2 + 4a2(4)n-2. Dividing both sides by 4n-2, we get (a1/4)(1)n-2 + a2(1)n-2 = (a1/4)(1)n-3 + a2(4)n-3 + a1(1)n-4 + a2(4)n-4. This equation holds for all n. Therefore, equating coefficients of like terms, we get a1/4 = a1/4, a2 = 4a2, a1 = a1/4, and a2 = 4a2. Solving these equations, we get a1 = a1/4 and a2 = 4a2.

Therfore, the general form of the solution is an = a1(1)n + a2(4)n.

The general form of the solutions of the recurring relation with the following characteristic equation is ( an=a1(1)n-a2(4)n.

The general form of the solutions of the recurrence relation with the characteristic equation (r-1)(r-4)=0 is a linear combination of the form an=a1(1)n+a2(4)n, where a1 and a2 are constants determined by the initial conditions of the recurrence relation.

This can be seen by factoring the characteristic equation into two linear factors: r-1=0 and r-4=0, which correspond to the two possible roots of the characteristic equation.

The solution to the recurrence relation is a linear combination of these two roots raised to the power of n, with the coefficients determined by the initial values of the sequence.

Therefore, the correct answer is A.

Answer:

-2 to 0.8 seems to be like than..

Answer:

10

Step-by-step explanation:

If Salma sold 60 cups of lemonade with total 920 ounces, then the number of small cups is 10 and the number of large cups is 50.

The problem can be translated into a system of linear equations.

Let:

p = the number of small cups sold

q = the number of large cups sold

"Salma sold 60 cups"  can be translated into equation:

p + q = 60   (equation 1)

"totaling 920 ounces" can be translated into equation:

12p + 16q = 920  (equation 2)

Multiply equation 1 by 12 then substracted from equation 2:

12p + 16q = 920

12p + 12q = 720 _

          4q = 200

            q = 50

Substitute q = 50 into equation 1:

p + 50 = 60

p = 10

Hence, the number of small cups = 10, the number of large cups = 50.

V(4X) = 64, where X has a discrete uniform distribution on the integers 2 to 5.

We ought to discover the 4X likelihood mass function. We know that the conceivable values ​​for X are 2, 3, 4, and 5, so the conceivable values ​​for 4X are 8, 12, 16, and 20. 

The probability that X takes one of these values ​​is 1/4 since X is a number between 2 and 5 and contains a discrete uniform conveyance.

 So the probability mass function for 4X is

P(4X = 8) = P(X = 2) = 1/4

P(4X = 12) = P(X = 3) = 1/4

P(4X = 16) = P(X = 4) = 1/4

P(4X = 20) = P(X = 5) = 1/4

Now we can use the formula for the variance of a discrete random variable.

\(V(4X) = E[(4X)^2] - [E(4X)]^2\)

where E represents the expected value.

To find E(4X), we can use the linearity of expectation.

E(4X) = 4E(X)

Since X has a discrete uniform distribution over the integers 2 to 5, its expected value is

E(X) = (2+3+4+5)/4 = 3.5

So E(4X) = 4(3,5) = 14. To find\(E[(4X)^2]\), we need to use the 4X probability mass function.

\(E[(4X)^2] = (8^2)(1/4) + (12^2)(1/4) + (16^2)(1/4) + (20^2)(1/ Four)\)

= 260

Now we can substitute these values ​​into the formula for V(4X).

\(V(4X) = E[(4X)^2] - [E(4X)]^2\)

\(= 260 - 14^2\)

= 260 - 196

= 64

Therefore V(4X) = 64.

Answer:

The choice B. q = 62

Step-by-step explanation:

\( - 55 + q = 7 \\ q = 7 + 55 \\ q = 62\)

We put the known on one end and the unknown on the other, and when we switch from one end to the other, the sign changes.

7=7# ans

The answer to the question is 530, C(N, 400), C(400, 270) * C(N - 400, 130) / C (N, 400), 0.95 respectively.

1) After catching the second batch of drones, the smallest number of drones N that might be in the wild, in total, is 530.

This is because we know that there are 400 tagged drones in the wild, and 130 untagged drones that we caught in the second batch.

Therefore, the smallest possible number of drones in the wild is 400 + 130 = 530.

2) The sample space of possible sets of 400 drones that you might catch in the second batch is the set of all possible combinations of 400 drones from the total number of drones in the wild.

The number of possible outcomes is given by the binomial coefficient C(N, 400), where N is the total number of drones in the wild.

3) The probability of catching exactly 270 tagged drones and 130 untagged drones, in the second batch, is given by the hypergeometric distribution:

P(X = 270) = C (400, 270) * C(N - 400, 130) / C(N, 400)

where N is the total number of drones in the wild, and C(n, k) is the binomial coefficient.

4) The number of drones N that makes your second batch results as likely as possible is the number that maximizes the probability of catching exactly 270 tagged drones and 130 untagged drones.

This can be found by taking the derivative of the probability with respect to N and setting it equal to zero, and solving for N.

This will give you the value of N that maximizes the probability.

5) To find the smallest nmax so that P(N ≤ nmax) = 0.95, we need to find the value of nmax that satisfies the equation:
P(N ≤ nmax) = C(400, 270) * C(nmax - 400, 130) / C(nmax, 400) = 0.95

Answer:

Step-by-step explanation:

x-y=7

-3x+9y=-39

Divide the second equation by 3

-x +3y = -13

Add this to the first equation

x-y=7

-x +3y = -13

----------------------

0x +2y = -6

Divide by 2

2y/2 = -6/2

y = -3

Now find x

x-y = 7

x -(-3) = 7

x+3 = 7

Subtract 3 from each side

x = 4

(4,-3)

Or by substitution

x-y=7  

solve for x

x = 7+y

-3x+9y=-39

Substitute y+7 in for x

-3(7+y) +9y = -39

Distribute

-21 -3y +9y = -39

Combine like terms

-21 +6y = -39

Add 21 to each side

The weakest correlation is represented by the value of c. 0.11.

The weakest correlation is represented by the value that is closest to zero, as it indicates a weaker relationship between the variables. In this case, the answer is: c. 0.11

A correlation coefficient of 0.11 is closer to zero than the other options provided, indicating a weaker correlation compared to the rest. The negative values (-0.75 and -0.27) represent negative correlations, but their magnitudes are larger than 0.11, making them stronger correlations (although still considered weak in general). The positive value of 0.54 represents a moderate positive correlation.

Answer:

Yes.

Step-by-step explanation:

This line is a linear function to be exact.

The correct option is b.Type I; Type II.

Rejecting the null hypothesis when it is true is called a type I error, whereas not rejecting a false null hypothesis is called a u type II error.

A type I error occurs when a null hypothesis that is true in the population is rejected. A false positive is an example of this type of error. A type II error occurs if a null hypothesis that is actually false in the population is not rejected. This type of error is known as a false negative.A type II error differs from a type I error in that a type I error rejects the null hypothesis when it is true (i.e., a false positive). The likelihood of making a type I error is equal to the level of significance set for the hypothesis test.

The second number in an ordered pair is the y-coordinate and corresponds to a number on the y-axis.

Step-by-step explanation:

hope this helps you! :)

The second number in an ordered pair is the y-coordinate and corresponds to a number of the y axis.

a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space

An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses.

An ordered pair contains the coordinates of one point in the coordinate system.

A point is named by its ordered pair of the form of (x, y).

In an order pair the first number represents the x coordinate and the second number represents the y coordinate.

To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.

Hence, the second number in an ordered pair is the y-coordinate and corresponds to a number of the y axis.
