Step-by-step explanation:
Volume = Length × Width × Height
Volume = 10 × 3 × 2
Volume = 60 cm
<span>73.7 inches is 2 standard deviations above the mean of 68.9 inches. The empirical rule states that 95% of the data for a normal distribution falls within 2 standard deviations of the mean. The tails on both ends account for the remaining 5%. Symmetry of the distribution then suggests that 2.5% of men are taller than 73.7 inches.</span>
Carbon is Carbon so it's just one atom.
Air is mostly O2, N2, H2O and ....
Salt is NaCl and not one atom ;)
Answer: exactly one solution
Explanation: first we have to solve it. so in 2 + 6x = 3x + 3 we have to subtract 2 from both sides and we get 6x = 3x + 1. then, we subtract 3x from both sides and we get 3x = 1. we divide both sides by 3 and get x = 1/3, which is the only solution.
hope this helped!
Answer: Between <u>2</u> and <u>2.5</u> seconds
How am I getting those values? Those values are selected from the 't' column on the left side of the table. These are time values in seconds. Note how t = 2 corresponds to h = 0.4; while t = 2.5 corresponds to h = -10.6
The change in sign for the height, from positive to negative, means that the height h must be zero at some point between t = 2 seconds and t = 2.5 seconds. We don't know where exactly, but we know that h = 0 at least once in this interval. This is because the height is a continuous function. There are no jumps or gaps in the height (the object can't teleport or anything)
