Point v is graphed on a number line at -6...point u is 8 units away from v....notice that it doesn't say which way....so it can go either way....so we need to find 8 units away from -6 in both directions
-6 + 8 = 2
-6 - 8 = -14
so point u can be either at 2 or at -14...ur answers are A and D
The diameters of the circles given are listed as: 2.5 cm, 3.1 cm, 3.7 cm, and 4.3 cm. It can be observed that there is a common difference between the terms of the progression such that the difference between the first two terms is 0.6 cm. The difference between the third and the second is also 0.6, and so on. Thus, the equation that will be able to represent the given is,
<em> f(n) = 2.5 + 0.6(n - 1)</em>
Answer:
4a. About 54 times NOT INCLUDING THE FIRST TRIAL
4b. About 60 times NOT INCLUDING THE FIRST TRIAL
Step-by-step explanation:
I say about because we don't know if it's ALWAYS going to be the same results.
4a. Also 12*4 because it's 20 times so 20*4=80 then you add half of it to become 90 and you get 54
4b. 12*5 because 100/5=20 for the 20 trials of them
Complete question:
Lizzie measured the length of a trail near her house. She discovered that her measurement had a margin of error of 0.0005 mile. Which of the following could be the measured length of the trail?
A. 9.3 miles
B. 9.2549 miles
C. 9.254 miles
D.9.25 miles
Answer:
- <u><em>B. 9.2549 miles</em></u>
Step-by-step explanation:
Measurements are subject to errors. Hence, when you make a measurement you must report it along with the error.
In this case, <em>Lizzie discovered that her measurement had a margin of error of 0.0005 mile.</em>
That means that the error of the measure is in the fourth decimal digit.
The measurement is supposed to be certain until the third decimal digit and the fourth digit would be uncertain.
The rule is that measures are reported with one uncertain digit.
Therefore, the <em>measured length</em> should contain 4 decimal digits, which means that , from the answer choices the measured length should be 9.2549 miles.
The measure should be reported as 9.2549 miles ± 0.0005 mile, meaning the the fourth decimal is uncertain. The uncertanity of the measure is 0.0005 mile.
