The problem needs determining the number of ones, fives, and twenties in a cashier's total of 30 bills, with more information regarding the relationship between twenties and ones and total value of the money.

To solve this, let's assign variables to represent the unknown quantities. Let's say the number of ones is x. Therefore, the number of twenties would be x + 9, according to the information given.

To calculate the total value of the money, we need to consider the value of each bill. A one-dollar bill has a value of $1, a five-dollar bill has a value of $5, and a twenty-dollar bill has a value of $20.

Now we can set up an equation to represent the total value:

x(1) + (x + 9)(20) + (30 - x - (x + 9))(5) = 351.

Simplifying the equation, we have:

x + 20x + 180 + 150 - 5x = 351,

36x + 330 = 351,

36x = 21,

x ≈ 0.583.

Since we cannot have a fraction of a bill, we must round the number of ones to the nearest whole number, which gives us 1. Therefore, there is 1 one-dollar bill.

The number of twenties can be found by substituting x into the expression x + 9, giving us 1 + 9 = 10 twenties.

Finally, to determine the number of fives, we subtract the total number of ones and twenties from the total number of bills: 30 - 1 - 10 = 19 fives.

Therefore, there is 1 one-dollar bill, 19 five-dollar bills, and 10 twenty-dollar bills in the cashier's total of 30 bills, amounting to a total value of $351.

Option C best describes the limiting values of T and a under the conditions given. In this case, T represents tension and a represents acceleration.

Without the specific conditions mentioned, it is impossible to determine the exact limiting values of T and a. However, certain options can be ruled out based on common sense and physical laws. For example, option C (T=mg and a=0) is not possible as the tension in a string cannot be equal to the weight of an object. Option E (T=0 and a=[infinity]) is also not possible as a mass cannot have zero tension and infinite acceleration.

Based on these eliminations, the most reasonable options are A (T=0 and a=0) and D (T=[infinity] and a=g). In the former case, the object is not moving and there is no tension in the string. In the latter case, the object is in free fall and the tension in the string is negligible compared to the weight of the object.

However, it is important to note that the exact limiting values of T and a will depend on the specific conditions of the scenario, such as the mass of the object and the angle of the string.

Option C best describes the limiting values of T and a under the conditions given. In this case, T represents tension and a represents acceleration. When T=mg and a=0, it means that the tension in the system is equal to the gravitational force acting on the mass (mg) and the system is in equilibrium with no acceleration. This is a common scenario when an object is hanging from a rope or cable and not moving. The other options do not represent stable or realistic conditions for a physical system.

B. No, because the Central Limit Theorem states that the sampling distribution of x is approximately normally distributed only if the sample size is large enough.

The Central Limit Theorem (CLT) is a fundamental concept in statistics that states that as the sample size increases, the sampling distribution of the sample means will approach a normal distribution. However, this is only true if certain conditions are met, one of which is having a large enough sample size.
The CLT states that the sampling distribution of x will be approximately normally distributed if the sample size is large enough (usually greater than 30). If the sample size is small, the sampling distribution may not be normally distributed. In such cases, other statistical techniques like the t-distribution should be used.
Furthermore, the CLT assumes that the population being sampled is not necessarily normally distributed, but it does require that the population has a finite variance. This means that even if the population is not normally distributed, the sampling distribution of x will still be approximately normal if the sample size is large enough.
In conclusion, the answer is B, as the Central Limit Theorem states that the sampling distribution of x is approximately normally distributed only if the sample size is large enough.

Third choice, option C

x = 5/2

To solve for the value of x if 9^(x-1) - 2 = 25, we can substitute each of the options into a simplified equation.

We could substitute each option into the given equation, but then we would have to simplify it four more times. It's easier to simplify once first.

\(9^{x-1} -2=25\)                   Start with the given equation

\(9^{x-1} -2+2=25+2\)       Add 2 to both sides

\(9^{x-1} =25+2\)                   –2 + 2 on the left side cancels out

\(9^{x-1} =27\)                         Add on the right side

We found a simplified equation.

Now, let's substitute each option choice for 'x' in the simplified equation. We only have to substitute choices until we find the choice that makes the left and right sides of the equation equal, but let's try all of the choices today.

\(9^{x-1} =27\)             Start with the simplified equation

\(\displaystyle{9^{\frac{1}{2}-1} =27}\)             Substitute x = 1/2

\(\displaystyle{9^{\frac{1}{2}-\frac{2}{2}} =27}\)            Find a common denominator within the exponent

\(\displaystyle{9^{\frac{1-2}{2}} =27}\)             Combine numerators and subtract

\(\displaystyle{9^{-\frac{1}{2}} =27}\)  

\(\displaystyle{(3^{2})^{-\frac{1}{2}} =27}\)          Convert 9 into a base and exponent

\(\displaystyle{ 3^{ 2*-\frac{1}{2} } =27 }\)           Multiply exponents

\(\displaystyle{ 3^{ -\frac{2*1}{2} } =27 }\)            Combine into numerator

\(\displaystyle{ 3^{ -\frac{2}{2} } =27 }\)              Simplify the fraction

\(\displaystyle{ 3^{ -1 } =27 }\)               Use negative exponent rule to simplify

\(\displaystyle{ \frac{1}{3^{1}} =27 }\)                 Simplify the denominator

\(\displaystyle{ \frac{1}{3} \neq 27 }\)                   Left and right sides are not equal

So, x is not equal to 1/2.

\(9^{x-1} =27\)              Start with the simplified equation

\(9^{2-1} =27\)             Substitute x = 2

\(9^{1} =27\)                 Subtract within the exponent

\(9 \neq 27\)                   Left and right sides are not equal

So, x is not equal to 2.

\(9^{x-1} =27\)             Start with the simplified equation

\(\displaystyle{9^{\frac{5}{2}-1} =27}\)            Substitute x = 5/2

\(\displaystyle{9^{\frac{5}{2}-\frac{2}{2}} =27}\)            Find a common denominator within the exponent

\(\displaystyle{9^{\frac{5-2}{2}} =27}\)             Combine numerators and subtract

\(\displaystyle{9^{\frac{3}{2}} =27}\)                Use fractional exponent rule to simplify

\(\displaystyle{\sqrt[2]{9^{3}} =27}\)              

\(\displaystyle{\sqrt{9^{3}} =27}\)  

\(\displaystyle{\sqrt{9 * 9 * 9} =27}\)     Solve the exponent by multiplying bases

\(\displaystyle{\sqrt{729} =27}\)            Solve the root

\(\displaystyle{27 =27}\)                 Left and right sides are equal

So, x is equal to 5/2.

\(9^{x-1} =27\)             Start with the simplified equation

\(9^{4-1} =27\)             Substitute x = 4

\(9^{3} =27\)                 Subtract within the exponent

\(9*9*9 =27\)        Solve the exponent by multiplying bases

\(729 \neq 27\)               Left and right sides are not equal

So, x is not equal to 4.

∴ in \(9^{x-1} -2=25\), x is equal to \(\displatestyle{\frac{5}{2}}\), making option C correct.

To find the area of the shaded region, we will need to find the areas of both the rectangle and the circle:

Rectangle: A = l × w

A = 11 × 12

A = 132 cm²

Circle: A = πr²  (Let π = 3.14)

A = π(2)²

A = 4π

A ≈12.56 cm²

Subtract the area of the circle from the area of the rectangle:

132 - 12.56 = 119.44 cm².

Answer:

47°

Step-by-step explanation:

Given that m<BOC = 6x + 29, m<AOB = 3x + 124, and m<AOC is a straight angle, therefore, m<AOC = 180°.

m<BOC +m<AOB = 180°

6x + 29 + 3x + 124 = 180

Solve for x

6x + 3x + 29 + 124 = 180

9x + 153 = 180

Subtract both sides by 153

9x = 180 - 153

9x = 27

Divide both sides by 9

x = 3

m<BOC = 6x + 29

Plug in the value of x

m<BOC = 6(3) + 29

m<BOC = 18 + 29 = 47°

That's a Congruent Triangle question.

The first thing that we should to analize is it: What figure is EFGH? The question say for us that \(\overline{EF} \cong \overline{GH}\) and \(\overline{EH} \cong \overline{GF}\), therefore, EFGH is a parallelogram because its parallel sides are congruents (equals).

Now, we should to proof that \(\triangle EFH \cong \triangle GHF\). The simbol "≅" means congruence, that is, \(\triangle EFH \cong \triangle GHF\) means that the triangles EFH and GHF are equals.

Let's proof:

\(\overline{HF}\) is a diagonal of the parallelogram EFGH. When we have a diagonal in a parallelogram, the opposite angles are congruents (look at the picture: the blue angles are congruent and the red angles are congruents too). Therefore, \(E\hat{F}H \cong F\hat{H}G\) and \(E\hat{H}F \cong H\hat{F}G\).

Both triangle has a comum side: the diagonal \(\overline{HF}\). The diagonal \(\overline{HF}\) is between two angles that we know that are congruents, Therefore, by the case ASA (Angle, Side, Angle), we proof that \(\triangle EFH \cong \triangle GHF\).

The probability of selecting a female student without aid is obtained by subtracting the probability of selecting a female student with aid from 1.

To find the probability of selecting a female student without aid, we can use the following information:

Total male students: 8,920,623

Total female students: 1,925,243

Percentage of male students receiving aid: 62.8%

Percentage of female students receiving aid: 66.8%

Percentage of male students receiving federal aid: 44.9%

Percentage of female students receiving federal aid: 51.6%

First, let's calculate the number of male students receiving aid:

Male students receiving aid = Total male students * Percentage of male students receiving aid

Male students receiving aid = 8,920,623 * 0.628

Next, let's calculate the number of male students receiving federal aid:

Male students receiving federal aid = Male students receiving aid * Percentage of male students receiving federal aid

Male students receiving federal aid = (8,920,623 * 0.628) * 0.449

Now, let's calculate the number of female students receiving aid:

Female students receiving aid = Total female students * Percentage of female students receiving aid

Female students receiving aid = 1,925,243 * 0.668

Finally, let's calculate the number of female students receiving federal aid:

Female students receiving federal aid = Female students receiving aid * Percentage of female students receiving federal aid

Female students receiving federal aid = (1,925,243 * 0.668) * 0.516

To find the probability of selecting a female student without aid, we need to calculate the complement of the event "selecting a female student with aid":

Probability of selecting a female student without aid = 1 - (Female students receiving federal aid / Total female students)

Now we can plug in the values and calculate the probability:

The given situation represents a binomial experiment, where there are only two possible outcomes for each trial: success (answering correctly) and failure (answering incorrectly). To find the probability of a particular number of successes, we use the binomial probability formula:

P(x)= nCx × p^x × q^(n-x)

Where, n is the total number of trials, p is the probability of success on each trial, q is the probability of failure on each trial (1-p), and x is the number of successes desired.

n = 14 (total number of questions)

p = 1/2 (probability of answering correctly when guessing randomly), and q = 1/2 (probability of answering incorrectly when guessing randomly).

To find P(5), we substitute these values in the formula
