Answer:
The answer is 49.1
Step-by-step explanation:
45.3 + 3.8 = 49.1
20/45 can be reduced to 4/9. That is the simplest form.
Answer:
Therefore the function that models the height of the object after t seconds is given by "H(t) = 15 + 8.5*t + 16.09*t²".
Step-by-step explanation:
Since the object has a initial velocity and it's being accelerated by gravity, than it's height is defined by:
H(t) = H(0) + V(0)*t + 0.5*g*t²
Applying the data from the problem, we have:
H(t) = 15 + 8.5*t + 0.5*32.17405*t²
H(t) = 15 + 8.5*t + 16.09*t²
Therefore the function that models the height of the object after t seconds is given by "H(t) = 15 + 8.5*t + 16.09*t²".
Answer:
The expected number of ducks that escape unhurt is:
5
Step-by-step explanation:
First the process is binomial process. Having said this, we have 10 hunters, and 10 ducks flying overhead while the hunter take their shot at the same time.
By expected value, we mean average or mean. And the mean of a binomial distribution is:
Mean => E(x) = np.
We must also know that there is only two probability possibilities:
1. The hunter hits the duck (p)
2. The hunter misses the duck (1-p) = q.
Hence;
p = 1/2, and (1-p) = 1/2.
Therefore;
E(x) = np; where n is the total number of hunter.
E(x) = 10*(1/2) = 5
The expected number of ducks that escape unhurt is 5
Answer:
<em>1:45 P.M</em>
Step-by-step explanation:
time = 60 + 45 + 60 + 40 + 60 + 5 = 180 + 90 = 270
270/60 = 4 hrs and 30 mins
6:15 - 4 hrs = 2:15
2:15 - 30 mins = 1:45 pm
