What’s the answer Please

Answer:

042

Step-by-step explanation:

682 has one correct placement this is the 2 becuase if we look at the 206 one we can see that the 6 is wrongly placed and 614 has one number wrongly placed, so it means that 2 is in the correct spot in 682.

Next, we can look at 206 and since we know the 2 is one of the values and 6 isn't, that leaves the 0.

Finally, we can eliminate al values of 7, 3, 8 because they are not correct. This leaves us with either 1 or 4 as the remaining variables. We know that we need the middle value, so that eliminates the 1.

To clarify this more, the code is 042.

Based on clue #1 and #2, we can say that 6 is not the correct number.

Now we know that the unlock code does not contain 6 and based on clue #3, we know that 2 and 0 are correct numbers but in the wrong position. From clue #1, 2‘s position should be on the right. The code is ??2.

Based on clue #5, 0‘s position should be on the left. The code is 0?2.

We have to find the missing number in the middle position. Based on clue #2, the middle number has to be 4. It cannot be 1, as the statement says that the number is wrongly placed.

We are left with 042.

A group of pennies made in 2018 are weighed. The mean is approximately 2.5 grams
Hatshy [7]

Answer:

*  The mean (a measure of central tendency) weight value is the average of the weights of all pennies in the study.

* The standard deviation (a measure of variability or dispersion) describes the lowest and highest any individual penny weight can be. Subtracting 0.02g from the mean, you get the lowest penny weight in the group.

Step-by-step explanation:

Recall that a penny is a money unit. It is created/produced, just like any other commodity. As a matter of fact, almost all types of money or currency are manufactured; with different materials ranging from paper to solid metals.

A group of pennies made in a certain year are weighed. The variable of interest here is weight of a penny.

The mean weight of all selected pennies is approximately 2.5grams.

The standard deviation of this mean value is 0.02grams.

In this context,

*  The mean (a measure of central tendency) weight value is the average of the weights of all pennies in the study.

* The standard deviation (a measure of variability or dispersion) describes the lowest and highest any individual penny weight can be. Subtracting 0.02g from the mean, you get the lowest penny weight in the group.

Likewise, adding 0.02g to the mean, you get the highest penny weight in the group.

Hence, the weight of each penny in this study, falls within

[2.48grams - 2.52grams]

Using data from 2010 and projected to 2020, the population of the United Kingdom (y, in millions) can be approximated by the equ
Nimfa-mama [501]

Answer:

In year 2030 the population is predicted to be 71.75 million

Step-by-step explanation:

* <em>Lets explain how to solve the problem</em>

- Using data from 2010 and projected to 2020, the population of

 the United Kingdom (y, in millions) can be approximated by the

 equation  10.0 y − 4.55 x = 581

- x is the number of years after 2000

- We need to know in what year the population is predicted to be

  71.75 million

* <em>Lets substitute the value of y in the equation by 71,75</em>

∵ The equation of the population is 10.0 y - 4.55 x = 581

∵ y = 71.75

∴ 10.0(71.75) - 4.55 x = 581

∴ 717.5 - 4.55 x = 581

- Subtract 717.5 from both sides

∴ - 4.55 x = - 136.5

- Divide both sides by - 4.55

∴ x = 30

∵ x represents the number of years after 2000

∵ 2000 + 30 = 2030

∴ In year 2030 the population is predicted to be 71.75 million
