<h3>1.</h3>
a. b=45d 45 baskets per day
b. D = 365
So B = 45 x 365 = 16 425
There would be 16,425 baskets produced in 1 non-leap-year.
<h3>2.</h3>
a. d= 23s
b. 1,380 ft.
Hope this helps you!
Have an amazing day :)
There will be 6 bands competing in the finals.
To find 15% for the finals, you need to multiply the total number of bands by 0.15. There are 41 total bands.
41 x 0.15 = 6.15 or about 6 bands
Answer:
1st formula 2n + 3m = 280
2nd formula 2n + 5m = 320
rearrange 1st formula to equal n:
2n = -3m + 280
n = -3/2 m + 140
rearrange 2nd formula to equal n:
2n = -5m + 320
n = -5/2m + 160
so now you have
-3/2m + 140 = -5/2m + 160
Rearrange to become:
-3/2m + 5/2m = 160 - 140
m = 20
Now place 20 into the very 1st equation in place of the letter m
2n + 3(20) = 280
2n + 60 = 280
2n = 220
n = 110
so it costs $110 per night, $20 per meal
Answer:
<u>Question 1: </u>
1. It is 95% certain that the true mean lies in the interval 16-36 years.
- Based on this sample, we are 95% confident that we captured the true mean in our sample. Not sure why the interval is wrong, though--it should be between 21-31 years (26 - 5, 26 + 5).
<u>Question 2: </u>
3. We are 95% confident that the true mean lies somewhere within 168-208 ng/ml.
- Again, the boundaries are wrong. THey should be between 178 and 198 ng/mL, but the rest of the sentence is correct.
<u>Question 3: </u>
2. Measures how far the sample mean is likely to be from the population mean
1. Can be calculated using the standard deviation of the population and the size of the sample
- The standard error is an approximation of the standard deviation that we use when we're not sure of the stdev or all the data values. Its purpose is to figure out how far the means were from each other, and approximate how far off our results were.
