False. The Army-McCarthy hearings did not result in a singular victory for McCarthyism.

The Army-McCarthy hearings were a series of hearings held in 1954 to investigate alleged communist infiltration in the U.S. Army. The hearings were televised and exposed Senator Joseph McCarthy's aggressive and unfounded accusations. During the hearings, McCarthy's credibility was severely damaged, and public opinion turned against him. The Army-McCarthy hearings marked a turning point in McCarthyism, as it was the first time McCarthy's tactics were publicly challenged and discredited. Ultimately, McCarthy was censured by the Senate, leading to the decline of his influence and the end of the McCarthy era. Therefore, the hearings did not result in a victory for McCarthyism but rather contributed to its downfall.

The inequality that describes the problem is 3x ≥ 18.

This means that the length of the rectangle (x) must be greater than or equal to 6 centimeters in order to ensure that the area of the rectangle is at least 18 square centimeters.

To calculate this, we need to rearrange the equation to x ≥ 6. This is done by dividing both sides of the equation by 3, which gives us the result of x ≥ 6.

To demonstrate this, we can assume that the length of the rectangle is 7 centimeters (x = 7). Plugging this value into the equation 3x ≥ 18 gives us 3(7) ≥ 18, which simplifies to 21 ≥ 18. Since this is true, we know that the length of the rectangle (7 centimeters) satisfies the inequality 3x ≥ 18.

The given distribution satisfies both conditions for a probability distribution, we can conclude that it is a probability distribution.

To determine whether the given distribution is a probability distribution, we need to check if the sum of all probabilities is equal to 1 and if all probabilities are non-negative.

Let's calculate the sum of all probabilities:

Sum of probabilities = 0.42 + 0.34 + 0.18 + 0.06 = 1

The sum of all probabilities is equal to 1, which satisfies the first condition for a probability distribution.

Now, let's check if all probabilities are non-negative:

All probabilities are greater than or equal to 0, which satisfies the second condition for a probability distribution.

Therefore, since the given distribution satisfies both conditions for a probability distribution, we can conclude that it is a probability distribution.

Answer:

a = 32

b =  6

Step-by-step explanation:

Givens

a = number of 2 point baskets

b = number of 3 point baskets.

a + b = 38

2a + 3b = 82

Solution

a + b = 38                         (1)

2a + 3b = 82                     (2)

Multiply (1) by 2 and put the result under (2)

2a + 3b = 82

2a + 2b = 76                         Subtract

b = 6

a + b = 38

a + 6 = 38                             Subtract  6 from both sides

a + 6 - 6 = 38 - 6

a = 32

a). The difference between the two population means is estimated at a location to be 2.7.

b). 49 different possible outcomes make up the t distribution. The margin of error at 95% confidence is 1.7.

c). The range of the difference between the two population means' 95% confidence interval is (0.0, 5.4).

d). The (0.0, 5.4) represents the 95% confidence interval for the difference among the two population means.

The variability or spread in a set of data is commonly measured by the standard deviation. The deviation between the values in the data set and the mean, or average, value, is measured. A low standard deviation, for instance, denotes a tendency for data values to be close to the mean, whereas a high standard deviation denotes a larger range of data values.

Using the equation \(x_1-x_2\), we can determine the point estimate of the difference between the two population means. In this instance, we calculate the point estimate as 2.7 by taking the mean of Sample

\(1(x_1=22.8)\) and deducting it from the mean of Sample \(2(x_2=20.1)\).

With the use of the equation \(df=n_1+n_2-2\), it is possible to determine the degrees of freedom for the t distribution. In this instance, the degrees of freedom are 49 because \(n_1\) = 20 and \(n_2\) = 30.

We must apply the formula to determine the margin of error at 95% confidence \(ME=t*\sqrt[s]{n}\).

The sample standard deviation (s) is equal to the average of \(s_1\) and \(s_2\) (3.4), the t value with 95% confidence is 1.67, and n is equal to the

average of \(n_1\) and \(n_2\) (25). When these values are entered into the formula, we get \(ME=1.67*\sqrt[3.4]{25}=1.7\).

Finally, we apply the procedure to determine the 95% confidence interval for the difference between the two population means \(CI=x_1-x_2+/-ME\).

The confidence interval's bottom limit in this instance is \(x_1-x_2-ME2.7-1.7=0.0\) and the upper limit is \(x_1+x_2+ME=2.7+1.7=5.4\).

As a result, the (0.0, 5.4) represents the 95% confidence interval for the difference among the two population means.

In the equation y = $7.20x + $790, "y" represents the total cost. An equation is a mathematical statement that shows the relationship between two or more variables. In this equation, there are two variables - "x" and "y". The variable "x" represents the number of units produced or sold, while "y" represents the total cost.

The coefficient of "x" in the equation, which is 7.20, represents the variable cost per unit. This means that for each unit produced or sold, there is an additional cost of $7.20. The constant term, which is $790, represents the total fixed costs. Fixed costs are those costs that do not vary with the number of units produced or sold.To find the total cost of producing or selling a certain number of units, we can plug in the value of "x" into the equation and solve for "y". For example, if we want to find the total cost of producing 100 units, we can substitute x=100 into the equation:
y = $7.20(100) + $790
y = $720 + $790
y = $1510
Therefore, the total cost of producing 100 units is $1510. In summary, "y" represents the total cost in the given equation, which is determined by both fixed and variable costs.
In the equation y = $7.20x + $790, "y" represents option C: total costs. This equation has two components: "$7.20x" represents the variable costs per unit, where x is the number of units, and "$790" represents the total fixed costs. By adding these two components together, you get the total costs (y) for producing x units.

b) The total cost of the purchase by Mrs. Singh is $58.50.

Algebraic expressions involve the combination of variables, numbers, constants, and values using mathematical operands (addition, subtraction, division, and multiplication).

The unit cost of folders = $2.50

The unit cost of notebooks = $4.00

The number of folders bought = 9

The number of notebooks bought = 9

Answer:

\(Fraction = \frac{2}{15}\)

Step-by-step explanation:

Given

Wall = 30 inches

Concrete = 16 inches

Brick = 10 inches

Limestone = 4 inches

Required

Fraction of the wall that is limestone

The fraction of limestone is calculated as follows;

\(Fraction = \frac{Size\ of\ limestone}{Size\ of\ wall}\)

Substitute 4 for size of limestone and 30 for size of size of wall

The formula becomes

\(Fraction = \frac{4}{30}\)

Divide numerator and denominator by 2

\(Fraction = \frac{4/2}{30/2}\)

\(Fraction = \frac{2}{15}\)

The fraction can not be further simplified; hence, the fraction of limestone is \(\frac{2}{15}\)

Answer:

2/15

Step-by-step explanation:

Fractions can be found by dividing the part by the whole.

part/whole

In this problem, the part is the limestone portion of the wall and the whole is the total width of the wall.

limestone/total

16 inches are concrete, 10 inches are brick and 4 inches are limestone. The total width is 30 inches.

limestone = 4

total = 30

4/30

This fraction can be simplified. Both the numerator and denominator can be evenly divided by 2.

(4/2) / (30/2)

2/ (30/2)

2/15

This fraction cannot be simplified further, therefore it is our answer.

2/15 of the wall is limestone.

Answer:

  82/99

Step-by-step explanation:

1. Notice the length of the repeating pattern.

  the pattern is 82 repeating, a 2-digit pattern

2. Notice where the repeating pattern starts, relative to the decimal point.

  the repeating starts at the decimal point

3. If the repeating starts at the decimal point, use a pattern of repeating 9s of the same length as the denominator of the fraction

  2 nines are the denominator: 82/99

4. Reduce the fraction if possible

  this fraction cannot be reduced

As a simplified fraction, 0.828282... = 82/99

Comment on more complicated cases

If the repeat does not start at the decimal point, or if the number contains an integer part, then the numerator of the fraction is found in a slightly different way. Let n be the number of repeating digits of the number x. The fraction is then ...

  (10^n·x -x)/(10^n -1)

Example:

  1.2345345345...        a number with a 3-digit repeat not starting at the decimal point

  (1234.5345... -1.2345...)/(1000 -1) = 1233.3/999  = 4111/3330

Let's use the number 3/4 as an example:
1. Convert the fraction to a decimal: To convert a fraction to a decimal, simply divide the numerator (top number) by the denominator (bottom number). 3 ÷ 4 = 0.75
2. Convert the fraction to a percent: To convert a fraction to a percent, divide the numerator by the denominator and then multiply the result by 100. (3 ÷ 4) × 100 = 75%
So, the number 3/4 can be written in two equivalent forms: as a decimal (0.75) and as a percent (75%). The equivalent decimal for the given fraction 3/4 is 0.75.
