2. Mark is having fun with bowling balls and clay. He drops balls from various heights and records their speed just before impact with a clay block. He then measures how
far into the clay the ball went. The table below shows his results.
a. Write an equation relating the speed o, to the depth of
Speed Depth
indentation d of the ball into the clay.
(m/s) (m)
1.30 0.02
5.00 0.30
9.13 1.00
b. If the ball is going 20 meters per second, how far into the
clay should it go?
10.00 1.20
12.91
15.00
2.00
2.70
20.00
7.50
C. How fast was the ball going to make a 7.5 meter impact
into the clay?

It’s kind of out of order but I’m confused! Please help

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
