How do you convert 3 1/2 to fraction notation also 9 7/8

Answers

Answer 1

Answer:

To convert 3 1/2 to a fraction, you would multiply the whole number, (3), by the denominator, (2), and add your sum to the numerator, (1). Your total would be 7/2. You would then follow the same steps for 9 7/8. Multiply 9 times 8 and get 72, then add 7 and your total is 79/8.

*The denominator stays the same in your final answer

Game wardens use experiments to help determine the number of deer in the state of North Carolina. Suppose 120 deer are caught, tagged, and released into the wild. A month later, 800 deer are caught with 16 found to have tags. Using this information, estimate the number of deer in North Carolina. A. 50
B. 500
C. 600
D. 6,000

Answers

Given;
120 deer tagged
800 deer caught
16 out of 800 deer caught have tags

This is a proportion problem

a/b = c/d where ac = bd

16/800 = 120/d
16d = 800*120
16d = 96,000
d = 96,000 / 16
d = 6,000

The estimate number of deer in North Carolina is D. 6,000

The weights (to the nearest pound) of some boxes to be shipped are found to be: Weight 65 68 69 70 71 72 90 95 frequency 1 2 5 8 7 3 2 2 Explain why or why not this could be represented by a bell curve (a normal distribution).

Answers

The given weights do not exhibit the characteristics of a bell curve or a normal distribution. The data is skewed, lacks a clear central tendency, and contains outliers. Therefore, it cannot be accurately represented by a normal distribution.

Here, we have,

To determine whether the given weights can be represented by a bell curve (normal distribution), we need to assess if the data exhibits the characteristics of a normal distribution.

Here are a few considerations:

Symmetry: A normal distribution is symmetric, meaning the data is equally distributed around the mean. In the given data, there are more observations on one side of the distribution (higher weights) than the other. This indicates a lack of symmetry, which is not characteristic of a bell curve.

Central tendency: A normal distribution typically has a single peak or mode at the center. In this case, there isn't a clear central tendency as the weights seem to be spread across different ranges without a dominant peak.

Outliers: Normal distributions tend to have minimal outliers or extreme values. The presence of weights like 90 and 95, which are noticeably higher than the other values, suggests the presence of outliers. This goes against the assumption of a bell curve.

Based on these considerations, it appears that the given weights do not exhibit the characteristics of a bell curve or a normal distribution. The data is skewed, lacks a clear central tendency, and contains outliers. Therefore, it cannot be accurately represented by a normal distribution.

because the data is not a normal distribution because the second half of the data is too far away from the first half i think its also called unproportional or something like that feel free to add me as a friend

A faucet leaks 4 oz. of water per minute. How many gallons of water are wasted in a year? (128 oz. = 1 gallon)

Answers

Answer: 16,425 gallons are wasted a year

Step-by-step explanation:

First find out how many minutes there are in a year then multiply it by how much oz the faucet leaks every years then convert it into gallons.

There are 525,600 minutes in a year now multiply it by 4.

525,600 * 4 = 2,102,400 So there are more than 2 million oz wasted in a year so now convert it to gallons.

If there are 128 oz for every gallons the divide 2,102,400 by 128 to find out how many gallons are wasted a year.

2,102,400 / 128 = 16,425

Final answer:

The faucet wastes 16,425 gallons of water in a year by leaking 4 oz. per minute. This is calculated by first determining the total ounces of water wasted in a year, and then converting it into gallons.

Explanation:

The question wants to know how many gallons of water are wasted in a year by a faucet that leaks 4 oz. of water per minute. To solve this, let's first convert everything into consistent units, and then use simple multiplication to find the answer.

First, remember that there are 60 minutes in an hour, 24 hours in a day, and 365 days in a year. Thus, the faucet wastes 4 * 60 * 24 * 365 = 2,102,400 ounces of water in a year.

Now, convert this to gallons. We know that 1 gallon = 128 ounces. Therefore, the faucet wastes 2,102,400 / 128 = 16,425 gallons of water in a year.
