Assume that a procedure yields a binomial distribution with a trial repeated n times. Use the binomial probability formula to fi
gladu [14]

Answer:

0.3032

Step-by-step explanation:

3 parameters [n,x,p] are given. We simply need the formula for binomial distribution and put in the values and solve.

The binomial distribution formula:

P(X=x)=nCx*p^{x}*(1-p)^{n-x}

Where nCx is the combination formula.

Now, we put the numbers and solve:

P(X=x)=nCx*p^{x}*(1-p)^{n-x}\\P(X=3)=6C3*(0.55)^{3}*(1-0.55)^{6-3}\\P(X=3)=\frac{6!}{(6-3)!*3!}(0.55)^3*(0.45)^3\\P(X=3)=20(0.55)^3*(0.45)^3\\P(X=3)=0.3032

julsineya [31]

Given:

The length between points on a map is 6 inches, 8 inches, and 9 inches.

The scale is one inch equals 5 miles.

To find:

The distances in miles.

Solution:

The given scale is:

1 inch = 5 miles

Using this scale, we get

6 inches = 6 × 5 miles

               = 30 miles

8 inches = 8 × 5 miles

               = 40 miles

9 inches = 9 × 5 miles

               = 45 miles

The distance is miles are 30, 40, 45 miles.

Therefore, the correct option is C.

<span>To find my answer, I subtracted 1195 from 2075 to get 880. Then I divided: 880 ÷ 1195 = 0.7364016736401674. Multiply that by 100 to get 73.64016736401674. Lastly, I rounded to the nearest whole percent to get 74.

Hope this helps,
