Samples of size n = 60 are randomly selected from the population of numbers (0 through 9) produced by a random-number generator,

and the mean is taken for each sample. What is the distribution of the sample means?

The distribution of the sample means when the samples of size n = 60 are randomly selected from the population is normal (approximately).

<h3>How is the sample explained?</h3>

Calculating the sample mean is as simple as adding up the number of items in a sample set and then dividing that sum by the number of items in the sample set.

Here, the distribution of the sample means when the samples of size n = 60 are randomly selected from the population is normal (approximately).

There's one piece of information missing from the question, so
in order to completely calculate the answer, we must assume the
missing number.

We have no information that helps us calculate the probability
that you will eat the first jelly bean.  So we'll have to assume that
you will definitely eat it, no matter what color it is.  The probability is 1 .

-- You start out with  (2 + 4 + 8 + 6) = 20 jelly beans in the package.
    8 of them are purple.

-- If you close your eyes and pull one out of the package, then the
probability that it will be purple is
                                                  8 / 20 .

-- You definitely eat it.  The probability of this event is 1 .

-- Now there are  19  jelly beans left in the package.
   6 of them are blue.

-- The probability of picking a blue one out of the package without peaking is

                             6 / 19 .

-- The probability of all three of these events happening is

                       (8/20) · (1) · (6/19)

                   =  (8 · 1 · 6) / (20 ·19)

                   =      48 / 380 

                   =  12/95  =  0.1263...  =  12.63...%  (rounded)

4. The system of equations 3x – 6y = 20 and 2x – 4y = 3 is
expeople1 [14]
3x - 6y = 20
-6y = -3x + 20
y = 1/2x - 20/6.....slope = 1/2...y int = -20/6 = -10/3

2x - 4y = 3
-4y = -2x + 3
y = 1/2x - 3/4..slope = 1/2...y int = -3/4

same slope, different y int = parallel lines = no solution = inconsistent

please help!!! the study conducted was 6 days long: there was 72mm of plant food and it decreased an equal amount each day.
Anuta_ua [19.1K]

Answer:

f(x) = 72 - 12x

Step-by-step explanation:

No. of days of study = 6

Amount of food to use for the 6 days = 72 mm

Given that equal amount of food was used each day, amount used per day = \frac{72}{6} = 12 mm

This would enable us derive a function for the amount of food remaining f(x), which can be expressed as a function of the number of days that have passed, (x).

Thus, we would have:

f(x) = 72 - 12x

Let's check if this equation expresses the relation of the function well.

At the end of day 1, if we used, 12mm, we would have 72 - 12 = 60mm of food remaining.

If we replace x in the equation we derived, we would get the same 60mm as the amount of food remaining.

If you try 2, 3, 4, 5 days, you'd get same thing.

At the end of the study, after the 6th day, the food would remain nothing.

Replace 6 for x in the relation function derived, you'd get a value of 0.
