Answer it takes away 2 than adds 3 and takes away 2 than instead of adding 3 on the fourth number it adds 6 so maybe it doubles the number it adds every time or it adds three onto the last number it added with and continues like that.

Step-by-step explanation:

Samir is an expert marksman. When he takes aim at a particular target on the shooting range, there is a 0.950.950, point, 95 pro
bearhunter [10]

The question is incomplete. Here is the complete question:

Samir is an expert marksman. When he takes aim at a particular target on the shooting range, there is a 0.95 probability that he will hit it. One day, Samir decides to attempt to hit  10 such targets in a row.

Assuming that Samir is equally likely to hit each of the 10 targets, what is the probability that he will miss at least one of them?

Answer:

40.13%

Step-by-step explanation:

Let 'A' be the event of not missing a target in 10 attempts.

Therefore, the complement of event 'A' is \overline A=\textrm{Missing a target at least once}

Now, Samir is equally likely to hit each of the 10 targets. Therefore, probability of hitting each target each time is same and equal to 0.95.

Now, P(A)=0.95^{10}=0.5987

We know that the sum of probability of an event and its complement is 1.

So, P(A)+P(\overline A)=1\\\\P(\overline A)=1-P(A)\\\\P(\overline A)=1-0.5987\\\\P(\overline A)=0.4013=40.13\%

Therefore, the probability of missing a target at least once in 10 attempts is 40.13%.

The heights of the trees in a forest are normally distributed, with a mean of 25 meters and a standard deviation of 6 meters. Wh
Alla [95]

Answer:

2.3%

Step-by-step explanation:

The formula to convert x into z distribution is

z=\frac{x-\mu}{\sigma}

Where z is the test statistic

x is what we are looking for (in this case 37)

\mu is the mean (in this case, it is 25)

\sigma is the standard deviation (we have 6)

<em>Plugging these into the formula, we get:</em>

z=\frac{x-\mu}{\sigma}\\z=\frac{37-25}{6}\\z=2

Thus we can say we want P(z\geq 2)

<u>Note: </u> P(z\geq a)=1-P(z\leq a)

The table given is for any  z where P(z\leq a)

Thus, now we have:

P(z\geq 2)\\=1-P(z\leq 2)\\=1-0.9772\\=0.0228\\

0.0228 into percentage is 0.0228 * 100 = 2.28%

Rounded, we get 2.3%

Third answer choice is right.

harina [27]
3 rolls of carpet

the square footage of 40ft*60ft=2,400
well then you divide it and you would need 3 rolls because the answer is 2.6 and then you would just round up
