4. The minute hand of a clock is 10 cm in length and begins by pointing at the
the 7
number 9 on the face of the clock.
a) Draw this clock face and collect data
representing the distance of the tip
of the minute hand above or below
the level of 9 on the face of the clock,
relative to the angle of rotation.
b) Use your data to sketch a graph of the
angle versus the distance above or below
the number 9.
c) How does this graph compare to that of
y = sin e?

step-by-step explanation:

you'll have to attache the image of the bar graph in order for us to answer : )

step-by-step explanation:

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
