Answer:

0.53

Step-by-step explanation:

This is a case of joint probability.  The probability that the first person chosen is wearing a belt is 0.73; the prob. that the second person chosen is wearing a belt is 0.73.  The joint probability, that is, the probability that both of the two people chosen at random are wearing their belts, is 0.73^2, or 0.53.  This assumes that the event that a given person is wearing his belt is completely independent of the event that some other person is also.

Answer:

They would have a medium-highish chance of them wearing seat belts

Step-by-step explanation:

This is because 73% is a bit ways above 50%, so there would be a high-ish chance of them wearing it.  Hope this helps.

Maria has baked a cake for Cathy's birthday. The dimensions of the cake are inches by inches. The cake is going to be cut into s
zaharov [31]
5.55% = 1/18

So, cut the cake into 18 equal squares.

The cake is twice as long as it is wide, so that means cut half the cake (6 3/4 x 6 3/4) into 9 pieces, each with a side of 1/3 * 6 3/4 = 2 1/4 inches.

How many terms are in the expression shown? <br><br> 2n + 5 – 3p + 4q<br><br> 1<br> 2<br> 3<br> 4
MA_775_DIABLO [31]

Step-by-step explanation: A term can be a number, a variable, or a number times one or more variables.

So in this expression, the terms are +2n, +5, -3p, and +4q.

This means that there are <u>4</u> terms.

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.
