Surface Area of a cylinder 2(π•r²)+(2π•r)•h
So
If the diameter is 8 then the radius is 4. the height is 5.
so you have, 2(3.14•4²)+(2•3.14•4)•5
solve. PEMDAS
Parentheses & Exponents first.
2(3.14•16)+(2•3.14•4)•5
2(50.24)+(6.28•4)•5
2(50.24)+(25.12)•5
Multiplication & Division second (left to right)
100.48+125.6
Add & Subtract (left to right)
226.08cm
It is not binomial random variable , since the number of red cards is unknown in the deck of cards in the starting of experiment.
As given in the question,
Number of cards are unknown.
Number of red cards are unknown in the starting of experiment.
Number of times process done =10
For binomial random variable number of red cards should be known.
Therefore, it is not binomial random variable , since the number of red cards is unknown in the deck of cards in the starting of experiment.

First you can count multiples of 7 all the way up to 84. 7,14,21,28,35,42,49,56,63,70,77,and 84.
Or you can do 7 x 12 equals 84.
Second write down the long division way 84/7.
7 goes into 8 one time write 7 at the top then write one at the bottom bring down the 4 and make it 14
you know 7 x 2 = 14 so 12 x 7 equals 14.
The answer is 7 3/4 inches.
I noticed the word "train" in the problem and I knew I had to help you! :)
The answer is going to be ((m-6)*-6= -((6 * m-6)).
hope that helped
