Answer: 4
Step-by-step explanation:
For any binomial variable X having parameters n (total number of trials ) and p (probability of getting success in each event), the standard deviation is given by :-

As per given , we have
n= 100 , p= 20%=0.20
Then, the standard deviation of this binomial distribution is :

Hence, the standard deviation of this binomial distribution is <u>4</u>.
d=rt
r = 9 1/2 as an improper fraction (2*9 +1)/2 = 19/2
t = 1 3/4 as an improper fraction (4*1+3)/4 =7/4
d=rt
d = 19/2* 7/4 = 133/8
8 goes into 133 16 times with 5 left over

It is not very likely you would roll one six.
The equation which can determine v, the number of visits Ariana must make to earn a free movie ticket is given by :76=25+8.5v
v=6
What is the total number of points required for a free movie ticket?
The total number of points that Ariana needs to watch a free movie is 76 points, which can be earned by the sum of signing up points plus the number of visits(v) multiplied by the points per visit, 8.5 points
76=25+8.5v
We can make v the subject of the formula
76=25+8.5v
76-25=8.5v
51=8.5v
v=51/8.5
v=6
