Answer:
(a) 36.36%
(b) 0.36%
(c) 0.06%
Step-by-step explanation:
Given that the time intervals measured with a stopwatch have an uncertainty of about 0.2 s.
We want to know what is the percent uncertainty of a hand-timed measurement of:
(a) 5.5 s
Percentage = (0.2/5.5) × 100
≈ 36.36%
(b) 55 s
Percentage = (0.2/55)×100
≈ 0.36%
(c) 5.5 min
5.5 min = 5.5 × 60 s
= 330 s
Percentage = (0.2/330)×100
≈ 0.06%
The slope is 3x and the y intercept is 2 so it should be written like y=3x+2
Answer:
Column 1 is labeled x with entries negative 3, negative 2, 4, 7. Column 2 is labeled y with entries negative 1, 5, 0, negative 1
Step-by-step explanation:
When a value is repeated for an x-entry, the relation is not a function. The last choice describes a table with unique x values.
Answer:
the answer is 9
Step-by-step explanation:
15/100 ?/60
multiply 60 by 15 to get 900, the divide 900 by 100 to get <em>9</em>
