3/8 + 2/8 = 5/8
8/8 - 1/8 = 7/8
7/8 - 5/8 = 2/8 = 1/4
he used 1/4 to paint the bird house.
Answer: 45.03%
To find the answer for this problem, you first need to find the z-score for a value of 19.25.
The z-score is the number of standard deviations from the mean.
Here is the work for our z-score:
19.25 - 20 = -0.75 / 6 = -0.125
Now, you just have to use a standard normal distribution table and look up the probability for a z-score of -0.125. I used the average of the probability for z-scores of -0.12 and -0.13 to get 45.03%.
The place value of the 5 in 6.85 is in the thousandths place. The 8 would be the tenths place. Other than that I'm not quite sure what the question is asking.
The answer is 576. The polygon can be changed to be a huge square, so all you have to do is multiply the width with the length
