Situation D: Suppose that, in a one-minute period during an electrical storm, the number of lightning strikes on a radar antenna

Crank

Answer:

21.77% probability that the antenna will be struck exactly once during this time period.

Step-by-step explanation:

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.

In this question:

$\mu = 2.40$

Find the probability that the antenna will be struck exactly once during this time period.

This is P(X = 1).

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

$P(X = 1) = \frac{e^{-2.40}*2.40^{1}}{(1)!} = 0.2177$

21.77% probability that the antenna will be struck exactly once during this time period.

Maria bought a bag of flour so that she can make muffins it has a mass of 2.26 kg Shanice 450 g of flour to make one batch of mu

xenn [34]

Answer:

10 grams or 0.010kg

Step-by-step explanation:

The mass of the bag used to make flour is 2.26 kg = 2260 grams

Now, in order to find out how many badges she made, we would need to divide the weight of the bag by the amount needed to make a badge.

Therefore: $\frac{2260}{450} = 5.02$

We know now that the bag will make 5 batches and will have some left over. In order to find how much we used, we can multiply 5 * 450 = 2250.

Therefore, in order to make 5 batches, Maria used exactly 2250 grams of flour which in result left us with 10 grams of the bag.

Note: 2260 -2250 = 10 grams.

Subtract, in order to find how many you have left.

Hope this helps.

The cheetah traveled 1.75 times faster for the first 8 minutes than it did for the second 8 minutes. Was the distance traveled d

IgorC [24]

Yes,

Step-by Step explaination:

If the cheetah is going at a faster rate of speed the first run it has a farther distance

So it collects more distance. The slower they run in the short period of time, the less distance they rank up.
