Move the constant to the other side, so that you have variable on one side and constant on the other side
Answer:
6
Step-by-step explanation:
scale factor means the amount of times you need to multiply
so,
36/9
=6
Answer:
The probability distribution of X is:
Step-by-step explanation:
"Tossing a coin and getting H" can be modelled as a Bernoulli random variable. The variable X is a sum of 4 of this Bernoulli variables, we can model X as a binomial random variable, with p=0.5 and n=4.
The values X can take are: 0, 1, 2, 3 and 4.
The values of this probability are calculated as:
Where
p: is the probability of tossing a coin and getting a Heads
q: is the probability of tossing a coin and not getting a Heads.
The binomial number is a way to calculate the possible combinations of getting a certain amount of heads.
For example, in 4 tosses, there are 6 ways or combinations of getting 2 heads and 2 tails:
The rule is...
y = 2x + 1
so if x is 8...
y = 2(8) + 1
y = 17
