Answer:

So, she spends 3 hours more sleeping than doing the activities.

Step-by-step explanation:

Consider the provided information.

According to the graph, Avery spends 33% of time in sleeping and 19% of time in doing "other" activities.

There are 24 h in a day.

According to Sleep category: 33% of 24 is:

33 % of 24=0.33×24=7.92 h ≈8 hours  

We are rounding to 8 hr because the solution should be in hours as per the question requirement.

Other category: 19% of 24 is:

19 % of 24=0.19×24=4.56 h ≈5 hours  

The difference of time is:

8h-5h=3h

So, she spends 3 hours more sleeping than doing the activities.

Grasshoppers are distributed at random in a large field according to a Poisson process with parameter a 5 2 per square yard. How
HACTEHA [7]

In this question, the Poisson distribution is used.

Poisson distribution:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given interval.

Parameter of 5.2 per square yard:

This means that \mu = 5.2r, in which r is the radius.

How large should the radius R of a circular sampling region be taken so that the probability of finding at least one in the region equals 0.99?

We want:

P(X \geq 1) = 1 - P(X = 0) = 0.99

Thus:

P(X = 0) = 1 - 0.99 = 0.01

We have that:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 0) = \frac{e^{-5.2r}*(5.2r)^{0}}{(0)!} = e^{-5.2r}

Then

e^{-5.2r} = 0.01

\ln{e^{-5.2r}} = \ln{0.01}

-5.2r = \ln{0.01}

r = -\frac{\ln{0.01}}{5.2}

r = 0.89

Thus, the radius should be of at least 0.89.
