Answer:

y=-8-44

=-52

y=-20x+14

-52=-20x+14

-20x=-52-14

-20x=-66

x=-66

-20

y=3.3

The quantity of liters of the 2% and 66% solutions should you mix together is 4.75 and 11.25 liters.

let

x + y = 16

0.02x + 0.66y = 0.47 × 16

from (1)

x = 16 - y

Substitute into (2)

0.02x + 0.66y = 0.47 × 16

0.02(16 - y) + 0.66y = 7.52

0.32 - 0.02y + 0.66y = 7.52

- 0.02y + 0.66y = 7.52 - 0.32

0.64y = 7.20

y = 7.20/0.64

y = 11.25 liters

Substitute y = 11.25 liters into (1)

x + y = 16

x + 11.25 = 16

x = 16 - 11.25

x = 4.75 liters

The correct answer is up until now, you have gained 18,963,816 coins.

Initially, you were gaining 5 coins per minute. After 4 hours, the rate increased by 1 coin per minute, so you were gaining 6 coins per minute.

To calculate the number of coins gained, we need to convert the given time of 52674 hours to minutes. There are 60 minutes in an hour, so:

52674 hours * 60 minutes/hour = 3,160,440 minutes

Now we can calculate the number of coins gained:

For the first 4 hours:

4 hours * 60 minutes/hour * 5 coins/minute = 1,200 coins

For the remaining time:

(3,160,440 minutes - 4 hours * 60 minutes/hour) * 6 coins/minute = 18,962,616 coins

Adding the coins gained during the initial 4 hours to the coins gained during the remaining time:

1,200 coins + 18,962,616 coins = 18,963,816 coins

Therefore, up until now, you have gained 18,963,816 coins.

The probability that the sample mean is greater than 18 as calculated  is 0.8413.

Given data,

n = 36, sample size

μ = 17, population mean

σ = 6, population standard deviation

when x = 18

z = (18 - 17)/1 = 1

P(x <18) = 0.8413

Therefore , the probability = 0.8413

A population's standard deviation serves as a gauge for how widely distributed its individual data points are. It's a way to express how dispersed from the mean the data is.

While a large standard deviation indicates that the data is more spread, a small standard deviation indicates that the data points are often close to the mean.

To solve this problem, we can use the equation: Distance = Speed x Time. Julia's trip takes 4.58 hours.

Distance is usually calculated by measuring the length or space between two points, or finding the shortest route between two points.

To solve this problem, we can use the equation:

Distance = Speed x Time

For the first part of the journey, the distance is 1/3 of 3540km, which is 1180km. We can use this distance and the speed of 720km/h to calculate the time:

Time = 1180km/720km/h

= 1.63 hours

For the second part of the journey, the distance is 2/3 of 3540km, which is 2360km.

We can use this distance and the speed of 800km/h to calculate the time:

Time = 2360km/800km/h

= 2.95 hours

Therefore, the total time for Julia's trip is

1.63 hours + 2.95 hours = 4.58 hours.

In conclusion, Julia's trip takes 4.58 hours.

Answer:

x = \(\frac{11}{7}\)

Step-by-step explanation:

note that 64 = \(2^{6}\) and 32 = \(2^{5}\) , thus

\((2^{6}) ^{2x-1}\) = \((2^{5}) ^{x+1}\) , that is

\(2^{6(2x-1)}\) = \(2^{5(x+1)}\)

\(2^{12x-6}\) = \(2^{5x+5}\)

Since the bases on both sides are equal, then equate the exponents

12x - 6 = 5x + 5 ( subtract 5x from both sides )

7x - 6 = 5 ( add 6 to both sides )

7x = 11 ( divide both sides by 7 )

x = \(\frac{11}{7}\)

Thus i^4*i=i^5=1*i=i.

Therefore, i^5=i.

The shaded sections of the trapezoid are triangles.

We know how to find the area of triangles

A = 1/2 bh

Lets start with the left triangle

The bases is 1.1 inches and the height is 3.8 inches

A left triangle is

A = 1/2 ( 1.1) * 3.8 = 2.09

The right triangle has the same dimensions

A right triangle is

A = 1/2 ( 1.1) * 3.8 = 2.09

Add the two triangles together

2.09+2.09 = 4.18 in^2

The area of the shaded region is 4.18 in^2

The overestimate is 76, the underestimate is 34, and the average of the two is 55 and the volume of the object of 64.

To approximate the volume of the object, we can divide the base into four subrectangles of equal width, with each having a width of 1. The height of each subrectangle is given by the function f(x,y) = xy.

Subrectangle 1: (0,0) to (1,4), height = f(0.5, 2) = 1

Subrectangle 2: (1,0) to (2,4), height = f(1.5, 2) = 3

Subrectangle 3: (2,0) to (3,4), height = f(2.5, 2) = 5

Subrectangle 4: (3,0) to (4,4), height = f(3.5, 2) = 7

The volume of each subrectangle can be found by multiplying its width, height, and depth (which is equal to 4). So, the volume of the object can be approximated by:

V ≈ (1 x 4) + (3 x 4) + (5 x 4) + (7 x 4)
V ≈ 64

To find the overestimate and underestimate, we can use the maximum and minimum values of f(x,y) within each subrectangle.

Overestimate: Using the maximum value of f(x,y), we get:

Vmax ≈ (1 x 4) + (4 x 4) + (6 x 4) + (8 x 4)
Vmax ≈ 76

Underestimate: Using the minimum value of f(x,y), we get:

Vmin ≈ (0.5 x 4) + (1.5 x 4) + (2.5 x 4) + (3.5 x 4)
Vmin ≈ 34

To get the average, we can add the overestimate and underestimate and divide by 2:

Average = (Vmax + Vmin) / 2
Average = (76 + 34) / 2
Average = 55

Therefore, the overestimate is 76, the underestimate is 34, and the average of the two is 55.

For the linear equations provided by the coordinates in the table;

The first equation of this system is y = -2x.

The second equation of this system is y = x - 3.

The solution to the system is (1, -2).

We have four points (-5,10), (-1,2), (0,0), and (11,-22) for first equation, and four points (-8,-11), (-2,-5), (1,-2), and (7,4) the second equation.

The slope (m) is given by the formula (y2 - y1) / (x2 - x1).

For the first line, we can use the points (-5,10) and (-1,2)

m1 = (2 - 10) / (-1 - (-5)) = -8/4 = -2.

the first equation is y = -2x

the second line, we can use the points (-8,-11) and (-2,-5)

m2 = (-5 - -11) / (-2 - -8) = 6/6 = 1.

the second line has a slope of 1,

the equation should have the form y = x + c.

To find c, we can use one of the points, for instance (-2,-5):

-5 = -2 + c => c = -5 + 2 = -3.

So, the second equation is y = x - 3.

the solution to the system, we need to find where the two lines intersect.

y = -2x

y = x - 3

Setting both equation equally

-2x = x - 3

=> 3x = 3

=> x = 1.

Substituting x = 1 into the first equation

y = -2(1) = -2.

the solution to the system of linear equation would be (1, -2).
