In the USA, the mean weight of a woman has gone from 143 lbs in the 1970s to 166 lbs in the 2010s. What is the percent increase in the mean weight of a woman?

The question states that six friends buy four boxes of pretzel bites. They want to share the pretzel bites equally. To find out how many pretzel bites each friend gets, we need to divide the total number of pretzel bites by the number of friends.

Let's start by finding out the total number of pretzel bites in the four boxes. If each box has the same number of pretzel bites, we can divide the total number of pretzel bites by four.

Since the question does not provide information about the number of pretzel bites in each box, we will assume that each box has the same number. Let's call this unknown number "x".

To find the total number of pretzel bites, we multiply the number of boxes (4) by the number of pretzel bites in each box (x). This can be written as:

Total pretzel bites = 4 * x

Now, to find how many pretzel bites each friend gets, we divide the total pretzel bites by the number of friends (6). This can be written as:

Pretzel bites per friend = (4 * x) / 6

Unfortunately, without knowing the value of "x" or the specific number of pretzel bites in each box, we cannot calculate the exact number of pretzel bites each friend gets.

However, we can provide an example to help illustrate the concept. Let's say each box has 20 pretzel bites. In this case, the total number of pretzel bites would be 4 * 20 = 80. Dividing this by the number of friends (6), each friend would get approximately 13.33 pretzel bites.

Remember, this example is based on the assumption that each box has 20 pretzel bites. If the actual number of pretzel bites in each box is different, the result would vary.

In summary, without more information about the number of pretzel bites in each box, we cannot calculate the exact number of pretzel bites each friend gets. However, we can use the given information and assumptions to demonstrate how to approach the problem.

To find the percent increase in the mean weight of a woman in the USA, we need to compare the difference between the weights in the 1970s and the 2010s, and then express that difference as a percentage of the weight in the 1970s.

First, let's calculate the difference in weight between the two time periods. The weight in the 1970s is 143 lbs, and the weight in the 2010s is 166 lbs.

Difference in weight = 166 lbs - 143 lbs = 23 lbs

Next, let's calculate the percent increase. We can use the formula:

Percent increase = (Difference / Initial value) * 100

In this case, the initial value is the weight in the 1970s, which is 143 lbs.

Percent increase = (23 lbs / 143 lbs) * 100

Now, let's simplify the equation:

Percent increase = (0.1608) * 100

Percent increase = 16.08%

Therefore, the percent increase in the mean weight of a woman in the USA from the 1970s to the 2010s is approximately 16.08%.

It's important to note that this calculation assumes the given weights represent the entire population and may not accurately represent individual cases. Additionally, this calculation only provides the percentage increase in the mean weight and does not take into account other factors or variations within the population.
