The variation equation is qr = 25

<h3>How to determine the equation?</h3>

An inverse variation is represented as:

qr = k

Where k is the constant of variation

When q = 10 and r =2.5, we have:

k = 10 * 2.5

Evaluate

k = 25

Substitute k = 25 in qr = k

qr = 25

Hence, the equation is qr = 25

A jar contains black marbles and green marbles. Sixty percent of the marbles in the jar are green. A number generator simulates
Natali5045456 [20]

Answer:

The number generator is not fair. In most of the experiments, considerably less than 60% of the selected marbles are green.

Step-by-step explanation:

Run a significant number of times, a fair distribution should be a bell curve  centered on the 6 for 60%

When taking a sample from a population, which of the following is true?
salantis [7]

Answer:

The larger the number of items in the sample, the more closely the distribution of sample items will follow a bell-shaped curve

Step-by-step explanation:

The question is about the distribution of the sample

The sampling distribution, also called the distribution of the sample mean is the distribution for many samples drawn form population at random for large sizes.

As per central limit theorem, if samples of sufficiently large size to represent the population is drawn from the population, the sample means of all sample will follow a normal distribution and hence bell shaped.

So from the options we say a is incorrect because not always

b is incorrect because there is no mention about the chance.

c is incorrect because when we use sample variance we use t test

Option d is correct.

The larger the number of items in the sample, the more closely the distribution of sample items will follow a bell-shaped curve
