We need to find the direction the ball is moving, so wee have this parametric equation, namely:
The graph of this equation is given in figure below. So, we well substitute some values of t in the equation:
If t = 0x = 4 and y = 3
P0(4, 3)
if t = 1x = 3.08 and y = 5.52
P1(3.08, 5.52)
if t = 2x = 1.16 and y = 5.72
P2(1.16, 5.72)
So, as shown in the figure, the answer is

Answer:
1/4
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
the probability that a randomly chosen radio station in this city is a college radio station = number of college stations / total number of city radio stations
= 5/20
To transform to the simplest form. divide both the numerator and the denominator by 5
= 1/4
Answer: 48
=================================================
Explanation:
The keyword "of" means multiply
150% converts to the decimal form 1.5; you move the decimal point two spots to the left to go from percent form to decimal form
Putting those two facts together lead to...
150% of 32 = 1.5*32 = 48
----------------
Another approach:
x% = x/100
150% = 150/100 = 1.5
150% of 32 = 1.5*32 = 48
The last step is identical as before, but the conversion of 150% is slightly different this time.
------------------
Yet another approach:
100% of anything is itself
So 100% of 32 is 32
The extra 50% means we take half of 32 to get 16. Then we add that onto the 32 to get 16+32 = 48
To obtain the probability of obtaining heads at least 3 times out of 5 times we recall that in her simulation <span>she
assigned odd digits to represent heads and even digits to represent
tails. Thus, we count the simulated numbers to see in how many numbers
do we have 3 or more odd digits.
Below, the simulated numbers with 3 or more odd digits are bolded.
</span> <span>32766 53855 34591 27732
47406 31022 25144 72662
03087 35521 26658 81704
56212 72345 44019 <span>65311
</span>
We have 6 simulated numbers having 3 or more odd digits.
Therefore, </span><span>P("heads" at least 3 out of 5 times) = 6 / 16 = 3 / 8.</span>
