Answer: if someone can figure that out i will give you a cookie cuz that stuff looks a lil hard.

Step-by-step explanation:

- 4 ( 7a + 7 ) - 2a = 92

- 28a - 28 - 2a = 92

- 28a - 2a - 28 = 92

Collect like terms

- 30a - 28 = 92

Add both sides 28

- 30a - 28 + 28 = 92 + 28

- 30a = 120

Divide both sides by - 30

- 30a ÷ - 30 = 120 ÷ - 30

a. The corresponding eigenvalue for  -3\(4^2\)A is -23104

d. The corresponding eigenvalue for A+71I is 73

c. The corresponding eigenvalue for 8A is 16

d. The corresponding eigenvalue for \(A^-1\) is λ

Let v be an eigenvector of A corresponding to the eigenvalue 2, That is,

Av = 2v.

We have (\(-34^2A\))v

= \(-34^2\)(Av)

= \(-34^2\)(2v)

= -23104v.

Hence, the eigenvalue is -23104 corresponding to the eigenvector v.

We have (A+71I)v

= Av + 71Iv

= 2v + 71v

= 73v.

Therefore, 73 is an eigenvalue of A+71I corresponding to the eigenvector v.

We have (8A)v = 8(Av)

= 16v.

Thus, 16 is an eigenvalue of 8A corresponding to the eigenvector v.

Let λ be an eigenvalue of \(A^-1\), and let w be the corresponding eigenvector, i.e.,

\(A^-1w\) = λw.

Multiplying both sides by A,

w = λAw.

Substituting v = Aw,

w = λv.

Therefore, λ is an eigenvalue of \(A^-1\) corresponding to the eigenvector v.

(a) To find the corresponding eigenvalue for (-34)^2, we can square the eigenvalue 2:

(-34)^2 = 34^2 = 1156.

Therefore, the corresponding eigenvalue for (-34)^2 is 1156.

(b) To find the corresponding eigenvalue for A + 71, we add 71 to the eigenvalue 2:

2 + 71 = 73.

Therefore, the corresponding eigenvalue for A + 71 is 73.

(c) To find the corresponding eigenvalue for 8A, we multiply the eigenvalue 2 by 8:

2 * 8 = 16.

Therefore, the corresponding eigenvalue for 8A is 16.

(d) To find the corresponding eigenvalue for A^(-1), we take the reciprocal of the eigenvalue 2:

1/2 = 0.5.

Step-by-step explanation:

Let,

Chaperones = x

Student = y

x + y = 125

=> x = 125 - y (1)

23x + 16y = 2056

=> 23(125 - y) + 16y = 2056

=> 2875 - 23y + 16y = 2056

=> 2875 - 7y = 2056

=> 2875 - 2056 = 7y

=> 819 = 7y

=> 819/7 = y

=> 117 = y

From 1

=> x = 125 - 117

The total cost  of he meat with tax and tip is $ 22.42

To calculate the total cost with tax and tip, we need to follow these steps:

multiply the meal cost by the tip rate. when  the tip rate is 18%, we have:

Tip amount = $19.00 * 0.18 = $3.42

Add the meal cost, sales tax, and tip amount to get the total cost:

Total cost = Meal cost + Sales tax + Tip amount

= $19.00 + $3.42

= $ 22.42

Answer:  240 liters

=======================================================

Work Shown:

x = capacity of barrel in liters

This value of x is some positive real number. It represents the most amount of water the barrel can hold.

The problem states that the barrel is 2/3 full to start with. This means, we start off with (2/3)x liters of water. Then we subtract off 60 of them to get to 5/12 full, meaning we have (5/12)x liters left.

We can form this equation

(2/3)x - 60 = (5/12)x

Multiply both sides by 12 to clear out the fractions

(2/3)x - 60 = (5/12)x

12*( (2/3)x - 60 ) = 12*(5/12)x

12*(2/3)x - 12*60 = 12*(5/12)x

8x - 720 = 5x

From here we solve for x

8x - 5x = 720

3x = 720

x = 720/3

x = 240

The barrel's full capacity is 240 liters

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

Check:

2/3 of 240 = (2/3)*240 = 160

The barrel starts off with 160 liters of water inside.

We then use 60 of them to be left with 160-60 = 100 liters

Note how 100/240 = (5*20)/(12*20) = 5/12, showing that 100 liters out of 240 total reduces to the fraction 5/12. In other words, when we say "5/12 full" we mean 100 liters full. This helps confirm we have the right answer.

As, in our question we are doing 20 trials to get the number of on-time flights. Hence, this is a binomial experiment.

The value of p=0.8 and n=20

The probability that exactly 12 flights are on time = 0.1772

The probability that exactly fewer than 12 flights are on time =  0.1049

The probability that at least 12 flights are on time = 0.8951

The probability that between 10 and 12 flights, are on time = 0.1795

(a) Binomial probability is the probability of exactly 'k' successes on 'n' repeated trials in an experiment which has two possible outcomes.

As, in our question we are doing 20 trials to get the number of on-time flights. Hence, this is a binomial experiment.

(b) As, the probability of success on an individual trial is p and here success means the flight is on-time so the value of p be,

p = 80% = 0.8

As, we made 20 trials and n is the total number of trials then,

the value of n be,

n = 20

(c) Now, if the probability of success on an individual trial is p ,

Then the binomial probability is C(n,x)⋅p^x⋅(1−p)^(n−x)

The probability that exactly 12 flights are on time, be

P(X=12) = C(20,12)⋅(0.8)^12⋅(1−0.8)^(20-12)

P(X=12) = C(20,12)⋅(0.8)^12⋅(0.2)^(8)

P(X=12) = 10,07,760×0.0687×0.00000256

P(X=12) = 0.1772

(d) Now, the probability that exactly fewer than 12 flights are on time, be

P(X<12) = 1 - P(X>12)

So, P(X>12) = P(X=13)+P(X=14)+P(X=15)+P(X=16)+P(X=17)+P(X=18)+P(X=19)+P(X=20)

So, P(X>12) = 0.0545 + 0.0364 + 0.1746 + 0.2182 + 0.2054 + 0.1369 + 0.0576 + 0.0115

P(X>12) = 0.8951

P(X<12) = 1 - 0.8951

P(X<12) = 0.1049

(e)  Now, the probability that at least 12 flights are on time, be

P(X>12)=0.8951

(f) The probability that between 10 and 12 flights, are on time, be

P(X=10)+P(X=11)+P(X=12) = 0.0020 + 0.0003 + 0.1772

P(X=10)+P(X=11)+P(X=12) = 0.1795

The equation that represents the relationship between the number of cakes (x) and the price (p) is p = 12x.

From the given data, we can observe that the price of the cakes is directly proportional to the number of cakes made. As the number of cakes increases, the price also increases proportionally.

The equation p = 12x represents this relationship, where p represents the price of the cakes and x represents the number of cakes made. The coefficient 12 indicates that for every unit increase in the number of cakes (x), the price (p) increases by 12 units.

For example, when x = 1, the price (p) is 12. When x = 2, the price (p) is 24, and so on. The equation p = 12x can be used to calculate the price of the cakes for any given number of cakes made.

Answer:

It earned $60 in interest

Step-by-step explanation:

The volume of the solid generated by revolving the region bounded by the graphs of y = x, y ≥ 0, and x ≥ 0 about the x-axis is 0 cubic units.

To find the volume using the disk method, we integrate the cross-sectional areas of the disks formed by revolving the region about the x-axis. The region bounded by y = x and y = 0 represents the area under the curve y = x in the positive x-axis region.

The radius of each disk is given by the value of y, which is equal to x in this case. The volume of each disk can be expressed as dV = πx^2 * dx.To determine the limits of integration, we consider the x-values where the curves intersect. In this case, y = x intersects y = 0 at the origin (0, 0). Therefore, the integral for the volume is V = ∫(0 to c) πx^2 * dx, where c represents the x-value where the curves intersect.

Evaluating the integral, we have V = π∫(0 to c) x^2 * dx. Integrating x^2 with respect to x gives V = π * [x^3/3] evaluated from 0 to c. Since c represents the x-value where the curves intersect, we have c = 0. Substituting the limits of integration, the volume simplifies to V = π * (0^3/3 - 0^3/3) = 0.

Therefore, the volume of the solid generated by revolving the region bounded by the graphs of y = x, y ≥ 0, and x ≥ 0 about the x-axis is 0 cubic units.
