Answer:
36.5 inches
Step-by-step explanation:
Given
See attachment for the given data
Required
Which length is closest to 4.2lb
The given data is a linear dataset.
So, we start by calculating the slope (m)
Pick any two corresponding points from the table
So, we have:
So:
The linear equation is then calculated using:
This gives:
Open bracket
To get the length closest to 4.2lb,
we set 
Then solve for x
So, we have:
Collect like terms
Solve for x
Answer:
Step-by-step explanation:
Let he speed of the boat on the lake is x.
<u>Considering the speed of the current it will take him:</u>
- 22.5/(x + 6) + 22.5/(x - 6) = 9
- 2.5 / (x + 6) + 2.5 / (x - 6) = 1
- 2.5(x - 6 + x + 6) = (x + 6)(x - 6)
- 2.5*2x = x² - 36
- x² - 5x - 36 = 0
- x = (5 ± √(5² + 4*36))/2 = (5 ± 13) / 2
- x = (5 + 13)/2 = 9 mph (negative root is discarded as the speed should be positive)
Answer:
Range = 5, Median = 9, Mode = 7
Step-by-step explanation:
First, we put them in order from least to greatest.
So its 7, 7, 7, 8, 10, 11, 12, 12
The range is the largest number minus the smallest number, so 12-7=5. The range is 5.
The median is the number in the middle, so we cross off numbers from both sides. That leaves us with 8 and 10. The number between them is 9, so the median is 9. (the actual process to find the median if there's 2 numbers in the middle is by adding them together and dividing them by 2)
The mode is just which number appears the most often. So 7 is the mode.
