The number of solution of each of the equations -2x + 4 = 4 - 2x, 5 - 3x = -5 - 3x and 2 + 3x = 2 + 2x are infinite solution, no solution and one solution respectively.

Given the equations in the question;

a) -2x + 4 = 4 - 2x

b) 5 - 3x = -5 - 3x

c) 2 + 3x = 2 + 2x

To determine the number of solutions of each equation, solve for x.

a)

-2x + 4 = 4 - 2x

Solve for x

-2x + 2x + 4 - 4 = 4 - 4 - 2x + 2x

-2x + 2x = 4 - 4

0 = 0

Hence, the equation has infinite solutions.

b)

5 - 3x = -5 - 3x

Solve for x

5  - 5 - 3x + 3x = -5 - 5 - 3x + 3x

- 3x + 3x = -5 - 5

0 =  -10

Hence, the equation has no solution.

c)

2 + 3x = 2 + 2x

Solve for x

2 - 2 + 3x - 2x  = 2 - 2 + 2x - 2x

3x - 2x  = 2 - 2

x = 0

Hence, the equation has one solution.

The expected value for playing roulette if you bet $15 on red is $6.32

Probability is the study of the chances of occurrence of a result, which are obtained by the ratio between favorable cases and possible cases.

The expected value for playing roulette if you bet $15 on red can be calculated as follows:

There are 18 red compartments out of a total of 38 compartments (18 red + 18 black + 2 neither red nor black).

Therefore, the probability of the ball landing on red is 18/38 or 9/19.

If the ball lands on red, you win $15 in addition to keeping your original $15 bet. So your total payout is $30.

If the ball does not land on red, you lose your $15 bet.

Using the formula for expected value, we can calculate the expected value of betting $15 on red as:

Expected value = (probability of winning * payout for winning) - (probability of losing * amount lost)

Expected value = (9/19 * $30) - (10/19 * $15)

Expected value = $270/19 - $150/19

Expected value = $120/19

Therefore, the expected value for playing roulette if you bet $15 on red is $6.32

The area and perimeter of 2D shape of Rectangle is 6.8448cm and 11.04cm repectively. The area and perimeter of 2D shape of circle is 5.0761cm and 8.0028cm respectively.

2D shape of Rectangle with dimensions of Length is3.72 cm and Width is 1.84 cm. we can find the area of rectangle with formula Area = length x width and the formula of perimeter is Perimeter = 2(length + width).

Area = length x width = 3.72 cm x 1.84 cm = 6.8448 square cm (rounded to four decimal places)

Perimeter = 2(length + width) = 2(3.72 cm + 1.84 cm) = 11.04 cm

2D shape of Circle with dimension of diameter of 2.54 cm. we can find the area with formula Area = πr^2 and circumference with formula Circumference = 2πr

Radius = diameter / 2 = 2.54 cm / 2 = 1.27 cm

Answer:

t = 9

Step-by-step explanation:

We know that 1/3 of t is 3, so to find t, we have to multiply 3 x 3 because we want to find 3/3 or 1 of t. When we multiply 3 x 3, we get t = 9

OR

We could also solve it like this-

1/3 × t = 3

1/3 goes to the other side so it becomes: [tex]t = \frac{3}{1/3} \\[/tex]

The hydronium ion concentration in orange juice with pH 3.5 is 3.16 × 10⁻⁴

The hydronium ion is an important factor when dealing with chemical reactions that occur in aqueous solutions. Its concentration relative to hydroxide is a direct measure of the pH of a solution. It can be formed when an acid is present in water or simply in pure water.

Given that, the pH level, P, of a liquid can be determined from the hydronium ion (H3O+) concentration, c, using the equation P = –log(c). we need to determine the hydronium ion concentration in orange juice with pH level of 3.5

Therefore,

P = -log(c)

P = 3.5

Therefore,

3.5 = -log(c)

log(c) = -3.5

(10)⁻³⁵/₁₀ = c

c = 0.000316227766

c = 3.16 × 10⁻⁴

Answer: Let's call the first integer "x". Then, the second integer would be x + 1, and the third integer would be x + 2.

According to the problem, the sum of the first and the third integer is 8 more than the second integer:

x + (x + 2) = (x + 1) + 8

Simplifying the left side of the equation:

2x + 2 = x + 9

Subtracting x from both sides:

x + 2 = 9

Subtracting 2 from both sides:

x = 7

So the first integer is 7, the second integer is 8, and the third integer is 9. These are three consecutive integers that satisfy the condition in the problem.

The error of Improved Euler's Method is that it underestimates the true solution of the differential equation, leading to an inaccurate result.

Improved Euler's Method is used to approximate the solution to a differential equation. The method begins by using the initial value of the function, as well as its derivative at that point. The derivative is then multiplied by a step size, h, and added to the initial value to obtain an estimate of the function at the next point. This estimate is used to calculate the derivative at the new point, which is then multiplied by the same step size and added to the initial value to obtain the next estimate. This process is repeated until the desired solution is obtained. The error of Improved Euler's Method is that it underestimates the true solution of the differential equation, leading to an inaccurate result.

The value of the distance BC across the lake to the nearest foot is 463 ft.

In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle. All triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Unless when otherwise specified, this article discusses triangles in Euclidean geometry, namely the Euclidean plane.

Extend the segment AB and draw a perpendicular line from B to C.

From the figure we see that:

tan (42) = y / 325 + x

y = tan (42) (325 + x)

Also, tan (70) = y / x

y = tan(70) x

Equating the values of y together we have:

tan (42) (325 + x) = tan(70) x

x = 158.430

Given ab 12 ac 6 prove c is the midpoint is true because the midpoint of 12 is 6.

True sampling distribution sample which is proportion to be approximately normal is "Both np and n(1 P) are at least 10".

For the sampling distribution of the sample proportion to be approximately normal, the sample size must be sufficiently large, and the sample proportion must be neither too small nor too large.

Specifically, the sample size multiplied by the sample proportion (np) and the sample size multiplied by one minus the sample proportion (n(1-P)) must both be at least 10. This is known as the "success-failure" condition.

Option b is not entirely accurate, as a sample size greater than 30 is a rule of thumb for the Central Limit Theorem to apply, but it is not a strict requirement for normality.

Option c is incorrect as a sample proportion greater than 0.5 means the distribution is skewed towards one end and not normal.

Option d and e are the mean and variance of the binomial distribution and are not directly related to normality.

The probability that Machine A filled a randomly selected bottle, given that it is defective, is 2/3 or approximately 0.67.

Let's define the subsequent events:

A: Machine A filled the bottle.

A': The bottle wasn't mechanically filled A (i.e. filled by machine AC).

D: the bottle is defective.

The chance that a randomly selected bottle was filled by machine A, assuming that it is broken, is known as P(A|D). The Bayes theorem provides us with:

P(A|D) = P(D|A)P(A) / P(D)

The following three terms on the right-hand side must be calculated:

P(D|A): the probability that a bottle is flawed given that machine A filled it. 10% of the bottles filled by machine A are reported to be faulty. so P(D|A) = 0.1.

P(A): the previous probability that machine A filled a bottle. There are just two machines, both of which fill bottles., P(A) = P(A') = 0.5.

P(D): the slight possibility that a bottle is flawed. The law of total probability can be used to calculate this:

P(D) = P(D|A)P(A) + P(D|A')P(A') = 0.1 x 0.5 + 0.05 x 0.5 = 0.075

Now we can plug in the values:

P(A|D) = 0.1 x 0.5 / 0.075 = 2/3

Therefore, the probability that Machine A filled a randomly selected bottle, given that it is defective, is 2/3 or approximately 0.67.
