Solve for Y in this problem, ax + by = c

Answers

Answer 1

Answer: ax + by = c
subtract ax from both sides and get

by = c - ax
divide both sides by b and get
y= (c-ax)/b

The difference between a histogram and a frequency polygon is The frequency polygon is reported as a percent. The histogram employs bars whereas the midpoints are connected for a frequency polygon. Bars cannot be adjacent in a histogram. Open-ended classes can be accommodated with a frequency polygon.

Answers

Answer: The frequency polygon is reported as a percent, providing a more intuitive understanding of the data distribution. In contrast, a histogram employs bars to represent the frequencies of different data intervals. Unlike a histogram, where bars cannot be adjacent to maintain clarity, a frequency polygon connects the midpoints of each interval, creating a smooth line. Also, a frequency polygon allows for the inclusion of open-ended classes, making it more flexible in representing data with varying ranges.

Heights of adults vary according to anormal distribution with a mean of 5.5
feet and a standard deviation of 0.5
feet. Which of the following is the
probability that a randomly selected
adult has a height over 7 feet?

Answers

The probability that a randomly selected adult has a height over 7 feet is nearly 100%, which means it's very likely that a randomly selected adult will have a height over 7 feet in this normal distribution.

To find the probability that a randomly selected adult has a height over 7 feet in a normal distribution with a mean of 5.5 feet and a standard deviation of 0.5 feet, you can use the Z-score and the standard normal distribution table.

First, calculate the Z-score for a height of 7 feet using the formula:

$Z = (X - \mu)/(\sigma)$

Where:

- X is the value you're interested in (in this case, 7 feet).

- μ (mu) is the mean (5.5 feet).

- σ (sigma) is the standard deviation (0.5 feet).

$Z = (7 - 5.5)/(0.5)\n = (1.5)/(0.5) \n= 3$

Now, you have the Z-score, which represents how many standard deviations above the mean the height of 7 feet is.

Next, you can use a standard normal distribution table or calculator to find the probability associated with a Z-score of 3. In most standard normal distribution tables, a Z-score of 3 corresponds to a probability close to 1 (or 100%).
