60° + (90 - x)° = 180°
Can you take it from here?
Considering the given equation for the time, it is found that the length of the pendulum in this problem is of 38.40 ft.
<h3>What is the equation for the time it takes for the pendulum to swing back and forth?</h3>
The equation is given as follows:

In which l is the length of the pendulum.
In this problem, we have that
, hence:


l = 32 x 1.2
l = 38.4 ft.

Answer:
(b) reduce the variability of the poll result.
Step-by-step explanation:
when the sample size of an opinion poll is increased, more data will be gathered about the population, and when there is enough data present, The estimates that is made afterward base on the gathered data will be more accurate compare with when there is small sample size. It should be noted that when the sample size of an opinion poll is increased, it will reduce the variability of the poll result.
It's 9! or 9*8*7*6*5*4*3*2*1 which is equal to 362,880
