A glacier moves 152 ft a year how many inches a day does it move (hint 356 days in a year)
2 answers:
Have you done dimensional analysis? This is the perfect time to use it. You simply write the problem as a fraction: 152 ft / 1 yr. Then you multiply it by conversion factors until you get the units you want (in/day).
Then you simply multiply across (I hope I added the picture correctly).
You should get 4.997 inches in a day. (You should probably round the answer up to 5, but it depends on what your teacher is asking for.)

Answer:
<h2>Center: (3, 0)</h2><h2>Radius: 2√2</h2>Step-by-step explanation:
The equation of a circle in standard form:
(h, k) - center
r - radius
We have the equation:
Therefore
the center:
the radius:
According to empirical rule, the area under the normal distribution or "bell-shaped curve", when plotted as a function of the z-parameter can be defined in terms of percentages.
The z-parameter (or z-score) is defined as
where
x = value of random variable,
μ = the mean,
σ = standard deviation,
The total area under the curve = 1.
The curve below shows that within 2 standard deviations from the mean, the total area under the curve is 95% of the total area.
Answer: 95%
