Answer:
(1a) 9.54e-07 (1b) 0.9437 (2) 
Step-by-step explanation:
We have n = 10 questions. For each question in the multiple choice exam, we can choose the correct answer with probability p = 0.25 or an incorrect answer with probability q = 0.75 (just by guessing). Besides is reasonable to believe that questions are independent. Let X be the random variable that represents the number of correct answers (just by guessing) observed during the n = 10 questions, so, X have a binomial distribution.
(a) The probability of getting a perfect score just by guessing is
(b) The probability of getting at least one question correct, just by guessing
2. Each RUID is 9-digits long, there are 10 digits, each of the nine positions for a digit of the RUID has 10 posibilities except the 4th and 5th positions which must be both 0. For the multiplication rule there can be 
different RUIDS.
Steps:
"Of" means "x" (times)
For 20% pretend there is an imaginary decimal at the end and move that decimal all the way to the front.
Now what is .20 of (times) $60 = 12
I think that's what you wanted. The discount price
The right answer is: <em>The binomial expression 2w + 6 represents the length of the fish tank.</em>
Dylan has a fish tank, so we assume that this tank is a cube. In this way, the volume of the tank is given by this expression:
Where:
h: height
w: width
l: length
We know the following things:
FIRST.<em> He knows its height, h, is one inch less than twice the width, w.</em>
This can be expressed as the following equation:
SECOND. <em>The length, l, of the fish tank is seven inches longer than the height.</em>
We can express this statement as follows:
By substituting

Answer:
216 cubic meters
Step-by-step explanation:
to find the volume of any prism the equation is bh or base times height
the base is a triangle so you find the triangles area and multiply it by the height
8 * 6 * 1/2 = 24
24 * 9 = 216
216 cubic meters
