The condition that has not been met for conducting a z-test for a proportion is (b) The sample size is less than 10% of the population size.
In order to conduct a z-test for a proportion, certain conditions need to be met. The first condition is that the data should be a random sample from the population of interest (condition a), which has been met in this case as the students entering the room can be considered a random sample of the statistics class.
The third condition is that the product of the population proportion (p) and the sample size (n) should be greater than or equal to 10, and the product of the complement of the population proportion (1-p) and the sample size (n) should also be greater than or equal to 10 (condition c). However, the second condition (b) has not been met in this scenario. The sample size of 5 students is not less than 10% of the population size, which is 30.
Therefore, the sample size is not large enough to meet this condition. Consequently, the correct answer is (e) More than one condition is violated, as the other conditions are still satisfied.

What is a rectangle, exactly?
A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. As a result, it is sometimes referred to as an equiangular quadrilateral.
The term "parallelogram" can also be used to describe a rectangle because the opposing sides are equal and parallel.
The height of the first rectangle is 2 and the area is 6x^{2}. To get to 6x^{2} you have to multiply by 3x^2.

what is percentage ?In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100. Occasionally, the acronyms "pct.," "pct," and "pc" are also used. But it is commonly indicated by the percent sign, "%." The % amount has no dimensions. Percentages are essentially fractions when the denominator is 100. Use the percent sign (%) to indicate that a number is a percentage by placing it next to it. For instance, you score a 75% if you properly answer 75 out of 100 questions on a test (75/100). Divide the money by the total and multiply the result by 100 to calculate percentages. The formula for calculating the percentage is (value/total) x 100%.

Tao rode his bike for 20 min at 12mph. How many miles did he go?
Tao rode his bike for 4 miles.
What are the speed, distance, and time?
Speed, distance, and time are related concepts in physics, and the relationship between them is often represented by the equation:
Speed = Distance/Time
To find out how many miles Tao rode his bike, you can use the formula:
distance = speed x time
In this case, the speed is 12 mph (miles per hour) and the time is 20 minutes. To convert the time to hours, you need to divide 20 minutes by 60 minutes (1 hour) which gives us 0.33 hours.
So,
distance = 12 mph x 0.33 hours = 4 miles
Hence, Tao rode his bike for 4 miles.

What is the role of the base and exponent in an exponential expression?
In an exponential expression, a base is a number that is raised to a certain power, represented by the exponent. The base can be any real number, while the exponent must be a positive integer.
Some key points to remember about the base and exponent in an exponential expression are:
The base represents the number being multiplied by itself a certain number of times.The exponent represents the number of times the base is multiplied by itself.The value of the exponential expression is the product of the base raised to the power of the exponent.The exponent can be positive or negative, and a base of 1 or 0 will always result in 1 or 0 respectively.The base can be any real number, but the exponent must be a positive integer.For example, in the expression "2^3" (read as "2 raised to the power of 3"), the base is 2 and the exponent is 3. This means that 2 is being multiplied by itself 3 times (222 = 8). So the expression evaluates to 8.

How do you find the coordinates of a triangle with midpoints?
To find the coordinates of a triangle with midpoints, you must first calculate the midpoints of each side by averaging the coordinates of the two endpoints.
To find the coordinates of a triangle with midpoints, you first need to calculate the midpoints of each side of the triangle. To do this, take the two endpoints of the side and average their coordinates. For example, if the two endpoints are (x1, y1) and (x2, y2), then the midpoint would be ((x1+x2)/2, (y1+y2)/2). Once you have all the midpoints, you can use the midpoint formula to calculate the coordinates of the triangle. The midpoint formula states that the coordinates of the triangle can be found by taking the average of the midpoints of the three sides.

Answer: 185 minutes
c is the correct option
Step-by-step explanation:
let x = number of minutes
0.46x = 85.10
x = 85.10/0.46 = 185 minutes
Answer:
185 minutes
Step-by-step explanation:
See the attached worksheet. Note that there are no inequalites mentued in the problem. That eliminates options 1 and 4. Option 2 is set up correctly, except that the units are incorrect. The unit for 0.46 is $/min, not just $. The final unit should be minutes, not $.
Option 3 has the correct equation, and units. Note how the word problem can be translated to an equation. Start with setting up an equation, before mentally trying to answer the question. An guess at the answer might be helpful, but work with the equation to insure the details are included. A correct equation will allow proper unit cancellation, which will help verify that the answer is correct. In this case we wanted an answer with just minutes. Dividing $ by $/min reduces to only minutes ($/$/min = min).
========
Making an estimate first is a good safeguard against mistakes. We can mentally round up $0.46 to 50 cents/minute. If the total bill is almost $90, we'd expect an answer around 180 minutes ((90/0.5). We got 185, so we can feel comfortable that the problem was done correctly and quickly move on.

Eliminate the parameter in the equations y = t + 2 and x = t superscript one-half. How can the rectangular equation be described?.
The equation can be described as a quadratic equation.
What is a quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x or any algebraic equation of highest degree. The standard form of the quadratic equation in variable is ax^2 + bx + c = 0 with a ≠ 0, where a and b are coefficients and constant. Since a quadratic equation is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
In this case, we have given that:
y = t + 2
So, y – 2 = t
Now, substitute the value of t in the equation:
x = t^1/2
x = (y – 2) ^1/2
And, by squaring both sides we will get:
x^2 = y – 2
y = x^2 + 2
