Answer:

Solution given;

AB=16ft

AD=11ft

Area of triangle=½(11*16)=88ft²

Since it is pentagon

it has 5similar triangle

Area of pentagon=5×88ft²=440ft²

Consider rolling a fair die thrice and tossing a fair coin sixteen times. Assume that all the tosses and rolls are independent.
Trava [24]

The probability that the total number of heads in all the coin tosses equals 12 is 0.0273.

Given a fair dice and tossing a fair coin sixteen times.

We have to find the probability that the total number  of heads in all the coin tosses equals 12.

The probability lies between 0 and 1.

Probabiltiy of coming head when the coin is tossed 1 time is 0.5 and probability of coming tails is also 0.5.

Let X shows the sum of heads while tossing.

P(X=12)=?

We can find the probability using binomial theorem.

=16C_{12} (0.5)^{12} (0.5)^{2}

We have to toss sixteen times and out of 16 times we need head 12 times.

=16!/12!4!*0.00024*0.0625

=1820*0.000015

=0.0273

Hence the probability that the total number of heads in all the coin tosses equals 12 is  0.0273.

If there are n ants once a month how many will there be a month la
Elza [17]

Answer: 3<em>n</em> ants

Step-by-step explanation:

         If there are n ants one month, and the ants triple every month, then next month there will be 3<em>n</em> ants.

         We can multiply 3 by <em>n</em> to show it tripling.

      To test this, 3(10,000) = 30,000 and 3(270,000) = 810,000, which corresponds to what you've filled out in the table.

The manager of a warehouse would like to know how many errors are made when a product's serial number is read by
Inessa05 [86]

Answer:

14.625

Step-by-step explanation:

As per the situation the solution of mean and standard deviation change, based on all 12 samples is represented below:-

Mean of all 12 samples is shown below:-

= \dfrac{Sum \ of \ all \ the \ observations}{Total \ number \ of \ observation}

= \dfrac{36+14+21+39+11+2+33+45+34+17+1+29}{12}

So, the Mean = 23.5

and now,

The  Standard deviation of all 12 samples is shown below:-

= \sqrt{\frac{1}{12}} (36-23.5)^2+(14-23.5)^2+(21-23.5)^2+(39-23.5)^2+(11-23.5)^2+(2-23.5)^2+(33-23.5)^2+(45-23.5)^2+(34-23.5)^2+(17-23.5)^2+(1-23.5)^2+(29-23.5)^2}]

\sigma = 14.625

Therefore, we used the above equation to reach  the answer.
